documentation/poky-ref-manual/extendpoky.xml: removed pokylinux.org link

There was a link whose URL was http://autobuilder.pokylinux.org:8010. I changed the link to use yoctoproject.org. Note that this URL was not visible to the reader in the manual. However, it was there in the DocBook code.

-		    GNU GENERAL PUBLIC LICENSE
-		       Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
- 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-			    Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.  This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it.  (Some other Free Software Foundation software is covered by
-the GNU Lesser General Public License instead.)  You can apply it to
-your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must show them these terms so they know their
-rights.
-
-  We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
-  Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software.  If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary.  To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-		    GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License.  The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language.  (Hereinafter, translation is included without limitation in
-the term "modification".)  Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
-  1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
-  2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    b) You must cause any work that you distribute or publish, that in
-    whole or in part contains or is derived from the Program or any
-    part thereof, to be licensed as a whole at no charge to all third
-    parties under the terms of this License.
-
-    c) If the modified program normally reads commands interactively
-    when run, you must cause it, when started running for such
-    interactive use in the most ordinary way, to print or display an
-    announcement including an appropriate copyright notice and a
-    notice that there is no warranty (or else, saying that you provide
-    a warranty) and that users may redistribute the program under
-    these conditions, and telling the user how to view a copy of this
-    License.  (Exception: if the Program itself is interactive but
-    does not normally print such an announcement, your work based on
-    the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-    a) Accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of Sections
-    1 and 2 above on a medium customarily used for software interchange; or,
-
-    b) Accompany it with a written offer, valid for at least three
-    years, to give any third party, for a charge no more than your
-    cost of physically performing source distribution, a complete
-    machine-readable copy of the corresponding source code, to be
-    distributed under the terms of Sections 1 and 2 above on a medium
-    customarily used for software interchange; or,
-
-    c) Accompany it with the information you received as to the offer
-    to distribute corresponding source code.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form with such
-    an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it.  For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable.  However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-  5. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Program or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-  6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-  7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded.  In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-  9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation.  If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
-  10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission.  For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this.  Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
-			    NO WARRANTY
-
-  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
-  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.

+                          Poky Hardware README
+                          ====================
+
+This file gives details about using Poky with different hardware reference
+boards and consumer devices. A full list of target machines can be found by
+looking in the meta/conf/machine/ directory. If in doubt about using Poky with
+your hardware, consult the documentation for your board/device.
+
+Support for additional devices is normally added by creating BSP layers - for
+more information please see the Yocto Board Support Package (BSP) Developer's
+Guide - documentation source is in documentation/bspguide or download the PDF
+from:
+
+   http://yoctoproject.org/community/documentation
+
+Support for machines other than QEMU may be moved out to separate BSP layers in
+future versions.
+
+
+QEMU Emulation Targets
+======================
+
+To simplify development Poky supports building images to work with the QEMU
+emulator in system emulation mode. Several architectures are currently
+supported:
+
+  * ARM (qemuarm)
+  * x86 (qemux86)
+  * x86-64 (qemux86-64)
+  * PowerPC (qemuppc)
+  * MIPS (qemumips)
+
+Use of the QEMU images is covered in the Poky Reference Manual. The Poky
+MACHINE setting corresponding to the target is given in brackets.
+
+
+Hardware Reference Boards
+=========================
+
+The following boards are supported by Poky's core layer:
+
+  * Texas Instruments Beagleboard (beagleboard)
+  * Freescale MPC8315E-RDB (mpc8315e-rdb)
+  * Ubiquiti Networks RouterStation Pro (routerstationpro)
+
+For more information see the board's section below. The Poky MACHINE setting
+corresponding to the board is given in brackets.
+
+
+Consumer Devices
+================
+
+The following consumer devices are supported by Poky's core layer:
+
+  * Intel Atom based PCs and devices (atom-pc)
+
+For more information see the device's section below. The Poky MACHINE setting
+corresponding to the device is given in brackets.
+
+
+
+                      Specific Hardware Documentation
+                      ===============================
+
+
+Intel Atom based PCs and devices (atom-pc)
+==========================================
+
+The atom-pc MACHINE is tested on the following platforms:
+
+  o Asus eee901
+  o Acer Aspire One
+  o Toshiba NB305
+  o Intel Embedded Development Board 1-N450 (Black Sand)
+
+and is likely to work on many unlisted atom based devices. The MACHINE type
+supports ethernet, wifi, sound, and i915 graphics by default in addition to
+common PC input devices, busses, and so on.
+
+Depending on the device, it can boot from a traditional hard-disk, a USB device,
+or over the network. Writing poky generated images to physical media is
+straightforward with a caveat for USB devices. The following examples assume the
+target boot device is /dev/sdb, be sure to verify this and use the correct
+device as the following commands are run as root and are not reversable.
+
+Hard Disk:
+  1. Build a directdisk image format. This will generate proper partition tables
+     that will in turn be written to the physical media. For example:
+
+     $ bitbake poky-image-minimal-directdisk
+  
+  2. Use the "dd" utility to write the image to the raw block device. For example:
+
+     # dd if=poky-image-minimal-directdisk-atom-pc.hdddirect of=/dev/sdb
+
+USB Device:
+  1. Build an hddimg image format. This is a simple filesystem without partition
+     tables and is suitable for USB keys. For example:
+
+     $ bitbake poky-image-minimal-live
+
+  2. Use the "dd" utility to write the image to the raw block device. For
+     example:
+
+     # dd if=poky-image-minimal-live-atom-pc.hddimg of=/dev/sdb
+
+  If the device fails to boot with "Boot error" displayed, it is likely the BIOS
+  cannot understand the physical layout of the disk (or rather it expects a
+  particular layout and cannot handle anything else). There are two possible
+  solutions to this problem:
+
+  1. Change the BIOS USB Device setting to HDD mode. The label will vary by
+     device, but the idea is to force BIOS to read the Cylinder/Head/Sector
+     geometry from the device.
+
+  2. Without such an option, the BIOS generally boots the device in USB-ZIP
+     mode.
+
+     a. Configure the USB device for USB-ZIP mode:
+     
+     # mkdiskimage -4 /dev/sdb 0 63 62
+
+     Where 63 and 62 are the head and sector count as reported by fdisk.
+     Remove and reinsert the device to allow the kernel to detect the new
+     partition layout.
+
+     b. Copy the contents of the poky image to the USB-ZIP mode device:
+
+     # mount -o loop poky-image-minimal-live-atom-pc.hddimg  /tmp/image
+     # mount /dev/sdb4 /tmp/usbkey
+     # cp -rf /tmp/image/* /tmp/usbkey
+
+     c. Install the syslinux boot loader:
+

+
+Texas Instruments Beagleboard (beagleboard)
+===========================================
+
+The Beagleboard is an ARM Cortex-A8 development board with USB, DVI-D, S-Video,
+2D/3D accelerated graphics, audio, serial, JTAG, and SD/MMC. The xM adds a
+faster CPU, more RAM, an ethernet port, more USB ports, microSD, and removes
+the NAND flash. The beagleboard MACHINE is tested on the following platforms:
+
+  o Beagleboard C4
+  o Beagleboard xM Rev A
+
+The Beagleboard C4 has NAND, while the xM does not. For the sake of simplicity,
+these instructions assume you have erased the NAND on the C4 so its boot
+behavior matches that of the xM. To do this, issue the following commands from
+the u-boot prompt (note that the unlock may be unecessary depending on the
+version of u-boot installed on your board and only one of the erase commands
+will succeed):
+
+    # nand unlock
+    # nand erase
+    # nand erase.chip
+
+To further tailor these instructions for your board, please refer to the
+documentation at http://www.beagleboard.org.
+
+From a Linux system with access to the image files perform the following steps
+as root, replacing mmcblk0* with the SD card device on your machine (such as sdc
+if used via a usb card reader):
+
+  1. Partition and format an SD card:
+     # fdisk -lu /dev/mmcblk0
+     
+     Disk /dev/mmcblk0: 3951 MB, 3951034368 bytes
+     255 heads, 63 sectors/track, 480 cylinders, total 7716864 sectors
+     Units = sectors of 1 * 512 = 512 bytes
+     
+             Device Boot      Start         End      Blocks  Id System
+     /dev/mmcblk0p1   *          63      144584       72261   c Win95 FAT32 (LBA)
+     /dev/mmcblk0p2          144585      465884      160650  83 Linux
+
+     # mkfs.vfat -F 16 -n "boot" /dev/mmcblk0p1
+     # mke2fs -j -L "root" /dev/mmcblk0p2
+
+  The following assumes the SD card partition 1 and 2 are mounted at
+  /media/boot and /media/root respectively. Removing the card and reinserting
+  it will do just that on most modern Linux desktop environments.
+  
+  The files referenced below are made available after the build in
+  build/tmp/deploy/images.
+
+  2. Install the boot loaders
+     # cp MLO-beagleboard /media/boot/MLO
+     # cp u-boot-beagleboard.bin /media/boot/u-boot.bin
+
+  3. Install the root filesystem
+     # tar x -C /media/root -f poky-image-$IMAGE_TYPE-beagleboard.tar.bz2
+     # tar x -C /media/root -f modules-$KERNEL_VERSION-beagleboard.tgz
+
+  4. Install the kernel uImage
+     # cp uImage-beagleboard.bin /media/boot/uImage
+
+  5. Prepare a u-boot script to simplify the boot process
+     The Beagleboard can be made to boot at this point from the u-boot command
+     shell. To automate this process, generate a user.scr script as follows.
+
+     Install uboot-mkimage (from uboot-mkimage on Ubuntu or uboot-tools on Fedora).
+
+     Prepare a script config:
+
+     # (cat << EOF
+     setenv bootcmd 'mmc init; fatload mmc 0:1 0x80300000 uImage; bootm 0x80300000'
+     setenv bootargs 'console=tty0 console=ttyO2,115200n8 root=/dev/mmcblk0p2 rootwait rootfstype=ext3 ro'
+     boot
+     EOF
+     ) > serial-boot.cmd
+     # mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n "Core Minimal" -d ./serial-boot.cmd ./boot.scr
+     # cp boot.scr /media/boot
+
+   6. Unmount the SD partitions, insert the SD card into the Beagleboard, and
+      boot the Beagleboard
+
+Note: As of the 2.6.37 linux-yocto kernel recipe, the Beagleboard uses the
+      OMAP_SERIAL device (ttyO2). If you are using an older kernel, such as the
+      2.6.34 linux-yocto-stable, be sure to replace ttyO2 with ttyS2 above. You
+      should also override the machine SERIAL_CONSOLE in your local.conf in
+      order to setup the getty on the serial line:
+
+      SERIAL_CONSOLE_beagleboard = "115200 ttyS2"
+
+
+Freescale MPC8315E-RDB (mpc8315e-rdb)
+=====================================
+
+The MPC8315 PowerPC reference platform (MPC8315E-RDB) is aimed at hardware and
+software development of network attached storage (NAS) and digital media server
+applications. The MPC8315E-RDB features the PowerQUICC II Pro processor, which
+includes a built-in security accelerator.
+
+Setup instructions
+------------------
+
+You will need the following:
+* nfs root setup on your workstation
+* tftp server installed on your workstation
+
+Load the kernel and boot it as follows:
+
+ 1. Get the kernel (uImage.mpc8315erdb) and dtb (mpc8315erdb.dtb) files from
+    the Poky build tmp/deploy directory, and make them available on your tftp
+    server.
+
+ 2. Set up the environment in U-Boot:
+
+ =>setenv ipaddr <board ip>
+ =>setenv serverip <tftp server ip>
+ =>setenv bootargs root=/dev/nfs rw nfsroot=<nfsroot ip>:<rootfs path> ip=<board ip>:<server ip>:<gateway ip>:255.255.255.0:mpc8315e:eth0:off console=ttyS0,115200
+
+ 3. Download kernel and dtb to boot kernel.
+
+ =>tftp 800000 uImage.mpc8315erdb
+ =>tftp 780000 mpc8315erdb.dtb
+ =>bootm 800000 - 780000
+
+
+Ubiquiti Networks RouterStation Pro (routerstationpro)
+======================================================
+
+The RouterStation Pro is an Atheros AR7161 MIPS-based board. Geared towards
+networking applications, it has all of the usual features as well as three
+type IIIA mini-PCI slots and an on-board 3-port 10/100/1000 Ethernet switch,
+in addition to the 10/100/1000 Ethernet WAN port which supports
+Power-over-Ethernet.
+
+Setup instructions
+------------------
+
+You will need the following:
+* A serial cable - female to female (or female to male + gender changer)
+  NOTE: cable must be straight through, *not* a null modem cable.
+* USB flash drive or hard disk that is able to be powered from the
+  board's USB port.
+* tftp server installed on your workstation
+
+NOTE: in the following instructions it is assumed that /dev/sdb corresponds
+to the USB disk when it is plugged into your workstation. If this is not the
+case in your setup then please be careful to substitute the correct device
+name in all commands where appropriate.
+
+--- Preparation ---
+
+1) Build an image (e.g. poky-image-minimal) using "routerstationpro" as the
+MACHINE
+
+2) Partition the USB drive so that primary partition 1 is type Linux (83).
+Minimum size depends on your root image size - poky-image-minimal probably
+only needs 8-16MB, other images will need more.
+
+  # fdisk /dev/sdb
+  Command (m for help): p
+
+  Disk /dev/sdb: 4011 MB, 4011491328 bytes
+  124 heads, 62 sectors/track, 1019 cylinders, total 7834944 sectors
+  Units = sectors of 1 * 512 = 512 bytes
+  Sector size (logical/physical): 512 bytes / 512 bytes
+  I/O size (minimum/optimal): 512 bytes / 512 bytes
+  Disk identifier: 0x0009e87d
+
+     Device Boot      Start         End      Blocks   Id  System
+  /dev/sdb1              62     1952751      976345   83  Linux
+
+3) Format partition 1 on the USB as ext3
+
+  # mke2fs -j /dev/sdb1
+
+4) Mount partition 1 and then extract the contents of
+tmp/deploy/images/poky-image-XXXX.tar.bz2 into it (preserving permissions).
+
+  # mount /dev/sdb1 /media/sdb1
+  # cd /media/sdb1
+  # tar -xvjpf tmp/deploy/images/poky-image-XXXX.tar.bz2
+
+5) Unmount the USB drive and then plug it into the board's USB port
+
+6) Connect the board's serial port to your workstation and then start up
+your favourite serial terminal so that you will be able to interact with
+the serial console. If you don't have a favourite, picocom is suggested:
+
+  $ picocom /dev/ttyUSB0 -b 115200
+
+7) Connect the network into eth0 (the one that is NOT the 3 port switch). If
+you are using power-over-ethernet then the board will power up at this point.
+
+8) Start up the board, watch the serial console. Hit Ctrl+C to abort the
+autostart if the board is configured that way (it is by default). The
+bootloader's fconfig command can be used to disable autostart and configure
+the IP settings if you need to change them (default IP is 192.168.1.20).
+
+9) Make the kernel (tmp/deploy/images/vmlinux-routerstationpro.bin) available
+on the tftp server.
+
+10) If you are going to write the kernel to flash (optional - see "Booting a
+kernel directly" below for the alternative), remove the current kernel and
+rootfs flash partitions. You can list the partitions using the following
+bootloader command:
+
+  RedBoot> fis list
+
+You can delete the existing kernel and rootfs with these commands:
+
+  RedBoot> fis delete kernel
+  RedBoot> fis delete rootfs
+
+--- Booting a kernel directly ---
+
+1) Load the kernel using the following bootloader command:
+
+  RedBoot> load -m tftp -h <ip of tftp server> vmlinux-routerstationpro.bin
+
+You should see a message on it being successfully loaded.
+
+2) Execute the kernel:
+
+  RedBoot> exec -c "console=ttyS0,115200 root=/dev/sda1 rw rootdelay=2 board=UBNT-RSPRO"
+
+Note that specifying the command line with -c is important as linux-yocto does
+not provide a default command line.
+
+--- Writing a kernel to flash ---
+
+1) Go to your tftp server and gzip the kernel you want in flash. It should
+halve the size.
+
+2) Load the kernel using the following bootloader command:
+
+  RedBoot> load -r -b 0x80600000 -m tftp -h <ip of tftp server> vmlinux-routerstationpro.bin.gz
+
+This should output something similar to the following:
+
+  Raw file loaded 0x80600000-0x8087c537, assumed entry at 0x80600000
+
+Calculate the length by subtracting the first number from the second number
+and then rounding the result up to the nearest 0x1000.
+
+3) Using the length calculated above, create a flash partition for the kernel:
+
+  RedBoot> fis create -b 0x80600000 -l 0x240000 kernel
+
+(change 0x240000 to your rounded length -- change "kernel" to whatever
+you want to name your kernel)
+
+--- Booting a kernel from flash ---
+
+To boot the flashed kernel perform the following steps.
+
+1) At the bootloader prompt, load the kernel:
+
+  RedBoot> fis load -d -e kernel
+
+(Change the name "kernel" above if you chose something different earlier)
+
+(-e means 'elf', -d 'decompress')
+
+2) Execute the kernel using the exec command as above.
+
+--- Automating the boot process ---
+
+After writing the kernel to flash and testing the load and exec commands
+manually, you can automate the boot process with a boot script.
+
+1) RedBoot> fconfig
+   (Answer the questions not specified here as they pertain to your environment)
+2) Run script at boot: true
+  Boot script: 
+  .. fis load -d -e kernel
+  .. exec
+  Enter script, terminate with empty line
+  >> fis load -d -e kernel
+  >> exec -c "console=ttyS0,115200 root=/dev/sda1 rw rootdelay=2 board=UBNT-RSPRO"
+  >> 
+3) Answer the remaining questions and write the changes to flash:
+  Update RedBoot non-volatile configuration - continue (y/n)? y
+  ... Erase from 0xbfff0000-0xc0000000: .
+  ... Program from 0x87ff0000-0x88000000 at 0xbfff0000: .
+4) Power cycle the board.

+		    GNU GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

-		    GNU GENERAL PUBLIC LICENSE
-		       Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
- 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-			    Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.  This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it.  (Some other Free Software Foundation software is covered by
-the GNU Lesser General Public License instead.)  You can apply it to
-your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must show them these terms so they know their
-rights.
-
-  We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
-  Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software.  If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary.  To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-		    GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License.  The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language.  (Hereinafter, translation is included without limitation in
-the term "modification".)  Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
-  1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
-  2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    b) You must cause any work that you distribute or publish, that in
-    whole or in part contains or is derived from the Program or any
-    part thereof, to be licensed as a whole at no charge to all third
-    parties under the terms of this License.
-
-    c) If the modified program normally reads commands interactively
-    when run, you must cause it, when started running for such
-    interactive use in the most ordinary way, to print or display an
-    announcement including an appropriate copyright notice and a
-    notice that there is no warranty (or else, saying that you provide
-    a warranty) and that users may redistribute the program under
-    these conditions, and telling the user how to view a copy of this
-    License.  (Exception: if the Program itself is interactive but
-    does not normally print such an announcement, your work based on
-    the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-    a) Accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of Sections
-    1 and 2 above on a medium customarily used for software interchange; or,
-
-    b) Accompany it with a written offer, valid for at least three
-    years, to give any third party, for a charge no more than your
-    cost of physically performing source distribution, a complete
-    machine-readable copy of the corresponding source code, to be
-    distributed under the terms of Sections 1 and 2 above on a medium
-    customarily used for software interchange; or,
-
-    c) Accompany it with the information you received as to the offer
-    to distribute corresponding source code.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form with such
-    an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it.  For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable.  However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-  5. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Program or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-  6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-  7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded.  In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-  9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation.  If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
-  10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission.  For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this.  Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
-			    NO WARRANTY
-
-  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
-  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.

-Documentation
-=============
-
-This is the directory that contains the BitBake documentation. 
-
-Manual Organization
-===================
-
-Folders exist for individual manuals as follows:
-
-* bitbake-user-manual      - The BitBake User Manual 
-
-Each folder is self-contained regarding content and figures.
-
-If you want to find HTML versions of the BitBake manuals on the web,

-
-Sphinx
-======
-
-The BitBake documentation was migrated from the original DocBook
-format to Sphinx based documentation for the Yocto Project 3.2
-release.
-
-Additional information related to the Sphinx migration, and guidelines
-for developers willing to contribute to the BitBake documentation can
-be found in the Yocto Project Documentation README file:
-
-https://git.yoctoproject.org/cgit/cgit.cgi/yocto-docs/tree/documentation/README
-
-How to build the Yocto Project documentation
-============================================
-
-Sphinx is written in Python. While it might work with Python2, for
-obvious reasons, we will only support building the BitBake
-documentation with Python3.
-
-Sphinx might be available in your Linux distro packages repositories,
-however it is not recommend using distro packages, as they might be
-old versions, especially if you are using an LTS version of your
-distro. The recommended method to install Sphinx and all required
-dependencies is to use the Python Package Index (pip).
-
-To install all required packages run:
-
- $ pip3 install sphinx sphinx_rtd_theme pyyaml
-
-To build the documentation locally, run:
-
- $ cd documentation
- $ make html
-
-The resulting HTML index page will be _build/html/index.html, and you
-can browse your own copy of the locally generated documentation with
-your browser.

-Execution
-=========
-
-|
-
-The primary purpose for running BitBake is to produce some kind of
-output such as a single installable package, a kernel, a software
-development kit, or even a full, board-specific bootable Linux image,
-complete with bootloader, kernel, and root filesystem. Of course, you
-can execute the ``bitbake`` command with options that cause it to
-execute single tasks, compile single recipe files, capture or clear
-data, or simply return information about the execution environment.
-
-This chapter describes BitBake's execution process from start to finish
-when you use it to create an image. The execution process is launched
-using the following command form: ::
-
-  $ bitbake target
-
-For information on
-the BitBake command and its options, see ":ref:`The BitBake Command
-<bitbake-user-manual-command>`" section.
-
-.. note::
-
-   Prior to executing BitBake, you should take advantage of available
-   parallel thread execution on your build host by setting the
-   :term:`BB_NUMBER_THREADS` variable in
-   your project's ``local.conf`` configuration file.
-
-   A common method to determine this value for your build host is to run
-   the following: ::
-
-     $ grep processor /proc/cpuinfo
-
-   This command returns
-   the number of processors, which takes into account hyper-threading.
-   Thus, a quad-core build host with hyper-threading most likely shows
-   eight processors, which is the value you would then assign to
-   ``BB_NUMBER_THREADS``.
-
-   A possibly simpler solution is that some Linux distributions (e.g.
-   Debian and Ubuntu) provide the ``ncpus`` command.
-
-Parsing the Base Configuration Metadata
-=======================================
-
-The first thing BitBake does is parse base configuration metadata. Base
-configuration metadata consists of your project's ``bblayers.conf`` file
-to determine what layers BitBake needs to recognize, all necessary
-``layer.conf`` files (one from each layer), and ``bitbake.conf``. The
-data itself is of various types:
-
-  **Recipes:** Details about particular pieces of software.
-
-  **Class Data:** An abstraction of common build information (e.g. how to
-   build a Linux kernel).
-
-  **Configuration Data:** Machine-specific settings, policy decisions,
-   and so forth. Configuration data acts as the glue to bind everything
-   together.
-
-The ``layer.conf`` files are used to construct key variables such as
-:term:`BBPATH` and :term:`BBFILES`.
-``BBPATH`` is used to search for configuration and class files under the
-``conf`` and ``classes`` directories, respectively. ``BBFILES`` is used
-to locate both recipe and recipe append files (``.bb`` and
-``.bbappend``). If there is no ``bblayers.conf`` file, it is assumed the
-user has set the ``BBPATH`` and ``BBFILES`` directly in the environment.
-
-Next, the ``bitbake.conf`` file is located using the ``BBPATH`` variable
-that was just constructed. The ``bitbake.conf`` file may also include
-other configuration files using the ``include`` or ``require``
-directives.
-
-Prior to parsing configuration files, BitBake looks at certain
-variables, including:
-
-  :term:`BB_ENV_WHITELIST`
-  :term:`BB_ENV_EXTRAWHITE`
-  :term:`BB_PRESERVE_ENV`
-  :term:`BB_ORIGENV`
-  :term:`BITBAKE_UI`
-
-The first four variables in this list relate to how BitBake treats shell
-environment variables during task execution. By default, BitBake cleans
-the environment variables and provides tight control over the shell
-execution environment. However, through the use of these first four
-variables, you can apply your control regarding the environment
-variables allowed to be used by BitBake in the shell during execution of
-tasks. See the
-":ref:`bitbake-user-manual/bitbake-user-manual-metadata:Passing Information Into the Build Task Environment`"
-section and the information about these variables in the variable
-glossary for more information on how they work and on how to use them.
-
-The base configuration metadata is global and therefore affects all
-recipes and tasks that are executed.
-
-BitBake first searches the current working directory for an optional
-``conf/bblayers.conf`` configuration file. This file is expected to
-contain a :term:`BBLAYERS` variable that is a
-space-delimited list of 'layer' directories. Recall that if BitBake
-cannot find a ``bblayers.conf`` file, then it is assumed the user has
-set the ``BBPATH`` and ``BBFILES`` variables directly in the
-environment.
-
-For each directory (layer) in this list, a ``conf/layer.conf`` file is
-located and parsed with the :term:`LAYERDIR` variable
-being set to the directory where the layer was found. The idea is these
-files automatically set up :term:`BBPATH` and other
-variables correctly for a given build directory.
-
-BitBake then expects to find the ``conf/bitbake.conf`` file somewhere in
-the user-specified ``BBPATH``. That configuration file generally has
-include directives to pull in any other metadata such as files specific
-to the architecture, the machine, the local environment, and so forth.
-
-Only variable definitions and include directives are allowed in BitBake
-``.conf`` files. Some variables directly influence BitBake's behavior.
-These variables might have been set from the environment depending on
-the environment variables previously mentioned or set in the
-configuration files. The ":ref:`bitbake-user-manual/bitbake-user-manual-ref-variables:Variables Glossary`"
-chapter presents a full list of
-variables.
-
-After parsing configuration files, BitBake uses its rudimentary
-inheritance mechanism, which is through class files, to inherit some
-standard classes. BitBake parses a class when the inherit directive
-responsible for getting that class is encountered.
-
-The ``base.bbclass`` file is always included. Other classes that are
-specified in the configuration using the
-:term:`INHERIT` variable are also included. BitBake
-searches for class files in a ``classes`` subdirectory under the paths
-in ``BBPATH`` in the same way as configuration files.
-
-A good way to get an idea of the configuration files and the class files
-used in your execution environment is to run the following BitBake
-command: ::
-
-  $ bitbake -e > mybb.log
-
-Examining the top of the ``mybb.log``
-shows you the many configuration files and class files used in your
-execution environment.
-
-.. note::
-
-   You need to be aware of how BitBake parses curly braces. If a recipe
-   uses a closing curly brace within the function and the character has
-   no leading spaces, BitBake produces a parsing error. If you use a
-   pair of curly braces in a shell function, the closing curly brace
-   must not be located at the start of the line without leading spaces.
-
-   Here is an example that causes BitBake to produce a parsing error: ::
-
-      fakeroot create_shar() {
-         cat << "EOF" > ${SDK_DEPLOY}/${TOOLCHAIN_OUTPUTNAME}.sh
-      usage()
-      {
-         echo "test"
-         ######  The following "}" at the start of the line causes a parsing error ######
-      }
-      EOF
-      }
-
-      Writing the recipe this way avoids the error:
-      fakeroot create_shar() {
-         cat << "EOF" > ${SDK_DEPLOY}/${TOOLCHAIN_OUTPUTNAME}.sh
-      usage()
-      {
-         echo "test"
-         ###### The following "}" with a leading space at the start of the line avoids the error ######
-       }
-      EOF
-      }
-
-Locating and Parsing Recipes
-============================
-
-During the configuration phase, BitBake will have set
-:term:`BBFILES`. BitBake now uses it to construct a
-list of recipes to parse, along with any append files (``.bbappend``) to
-apply. ``BBFILES`` is a space-separated list of available files and
-supports wildcards. An example would be: ::
-
-  BBFILES = "/path/to/bbfiles/*.bb /path/to/appends/*.bbappend"
-
-BitBake parses each
-recipe and append file located with ``BBFILES`` and stores the values of
-various variables into the datastore.
-
-.. note::
-
-   Append files are applied in the order they are encountered in BBFILES.
-
-For each file, a fresh copy of the base configuration is made, then the
-recipe is parsed line by line. Any inherit statements cause BitBake to
-find and then parse class files (``.bbclass``) using
-:term:`BBPATH` as the search path. Finally, BitBake
-parses in order any append files found in ``BBFILES``.
-
-One common convention is to use the recipe filename to define pieces of
-metadata. For example, in ``bitbake.conf`` the recipe name and version
-are used to set the variables :term:`PN` and
-:term:`PV`: ::
-
-   PN = "${@bb.parse.BBHandler.vars_from_file(d.getVar('FILE', False),d)[0] or 'defaultpkgname'}"
-   PV = "${@bb.parse.BBHandler.vars_from_file(d.getVar('FILE', False),d)[1] or '1.0'}"
-
-In this example, a recipe called "something_1.2.3.bb" would set
-``PN`` to "something" and ``PV`` to "1.2.3".
-
-By the time parsing is complete for a recipe, BitBake has a list of
-tasks that the recipe defines and a set of data consisting of keys and
-values as well as dependency information about the tasks.
-
-BitBake does not need all of this information. It only needs a small
-subset of the information to make decisions about the recipe.
-Consequently, BitBake caches the values in which it is interested and
-does not store the rest of the information. Experience has shown it is
-faster to re-parse the metadata than to try and write it out to the disk
-and then reload it.
-
-Where possible, subsequent BitBake commands reuse this cache of recipe
-information. The validity of this cache is determined by first computing
-a checksum of the base configuration data (see
-:term:`BB_HASHCONFIG_WHITELIST`) and
-then checking if the checksum matches. If that checksum matches what is
-in the cache and the recipe and class files have not changed, BitBake is
-able to use the cache. BitBake then reloads the cached information about
-the recipe instead of reparsing it from scratch.
-
-Recipe file collections exist to allow the user to have multiple
-repositories of ``.bb`` files that contain the same exact package. For
-example, one could easily use them to make one's own local copy of an
-upstream repository, but with custom modifications that one does not
-want upstream. Here is an example: ::
-
-  BBFILES = "/stuff/openembedded/*/*.bb /stuff/openembedded.modified/*/*.bb"
-  BBFILE_COLLECTIONS = "upstream local"
-  BBFILE_PATTERN_upstream = "^/stuff/openembedded/"
-  BBFILE_PATTERN_local = "^/stuff/openembedded.modified/"
-  BBFILE_PRIORITY_upstream = "5" BBFILE_PRIORITY_local = "10"
-
-.. note::
-
-   The layers mechanism is now the preferred method of collecting code.
-   While the collections code remains, its main use is to set layer
-   priorities and to deal with overlap (conflicts) between layers.
-
-.. _bb-bitbake-providers:
-
-Providers
-=========
-
-Assuming BitBake has been instructed to execute a target and that all
-the recipe files have been parsed, BitBake starts to figure out how to
-build the target. BitBake looks through the ``PROVIDES`` list for each
-of the recipes. A ``PROVIDES`` list is the list of names by which the
-recipe can be known. Each recipe's ``PROVIDES`` list is created
-implicitly through the recipe's :term:`PN` variable and
-explicitly through the recipe's :term:`PROVIDES`
-variable, which is optional.
-
-When a recipe uses ``PROVIDES``, that recipe's functionality can be
-found under an alternative name or names other than the implicit ``PN``
-name. As an example, suppose a recipe named ``keyboard_1.0.bb``
-contained the following: ::
-
-  PROVIDES += "fullkeyboard"
-
-The ``PROVIDES``
-list for this recipe becomes "keyboard", which is implicit, and
-"fullkeyboard", which is explicit. Consequently, the functionality found
-in ``keyboard_1.0.bb`` can be found under two different names.
-
-.. _bb-bitbake-preferences:
-
-Preferences
-===========
-
-The ``PROVIDES`` list is only part of the solution for figuring out a
-target's recipes. Because targets might have multiple providers, BitBake
-needs to prioritize providers by determining provider preferences.
-
-A common example in which a target has multiple providers is
-"virtual/kernel", which is on the ``PROVIDES`` list for each kernel
-recipe. Each machine often selects the best kernel provider by using a
-line similar to the following in the machine configuration file: ::
-
-  PREFERRED_PROVIDER_virtual/kernel = "linux-yocto"
-
-The default :term:`PREFERRED_PROVIDER` is the provider
-with the same name as the target. BitBake iterates through each target
-it needs to build and resolves them and their dependencies using this
-process.
-
-Understanding how providers are chosen is made complicated by the fact
-that multiple versions might exist for a given provider. BitBake
-defaults to the highest version of a provider. Version comparisons are
-made using the same method as Debian. You can use the
-:term:`PREFERRED_VERSION` variable to
-specify a particular version. You can influence the order by using the
-:term:`DEFAULT_PREFERENCE` variable.
-
-By default, files have a preference of "0". Setting
-``DEFAULT_PREFERENCE`` to "-1" makes the recipe unlikely to be used
-unless it is explicitly referenced. Setting ``DEFAULT_PREFERENCE`` to
-"1" makes it likely the recipe is used. ``PREFERRED_VERSION`` overrides
-any ``DEFAULT_PREFERENCE`` setting. ``DEFAULT_PREFERENCE`` is often used
-to mark newer and more experimental recipe versions until they have
-undergone sufficient testing to be considered stable.
-
-When there are multiple "versions" of a given recipe, BitBake defaults
-to selecting the most recent version, unless otherwise specified. If the
-recipe in question has a
-:term:`DEFAULT_PREFERENCE` set lower than
-the other recipes (default is 0), then it will not be selected. This
-allows the person or persons maintaining the repository of recipe files
-to specify their preference for the default selected version.
-Additionally, the user can specify their preferred version.
-
-If the first recipe is named ``a_1.1.bb``, then the
-:term:`PN` variable will be set to "a", and the
-:term:`PV` variable will be set to 1.1.
-
-Thus, if a recipe named ``a_1.2.bb`` exists, BitBake will choose 1.2 by
-default. However, if you define the following variable in a ``.conf``
-file that BitBake parses, you can change that preference: ::
-
-  PREFERRED_VERSION_a = "1.1"
-
-.. note::
-
-   It is common for a recipe to provide two versions -- a stable,
-   numbered (and preferred) version, and a version that is automatically
-   checked out from a source code repository that is considered more
-   "bleeding edge" but can be selected only explicitly.
-
-   For example, in the OpenEmbedded codebase, there is a standard,
-   versioned recipe file for BusyBox, ``busybox_1.22.1.bb``, but there
-   is also a Git-based version, ``busybox_git.bb``, which explicitly
-   contains the line ::
-
-     DEFAULT_PREFERENCE = "-1"
-
-   to ensure that the
-   numbered, stable version is always preferred unless the developer
-   selects otherwise.
-
-.. _bb-bitbake-dependencies:
-
-Dependencies
-============
-
-Each target BitBake builds consists of multiple tasks such as ``fetch``,
-``unpack``, ``patch``, ``configure``, and ``compile``. For best
-performance on multi-core systems, BitBake considers each task as an
-independent entity with its own set of dependencies.
-
-Dependencies are defined through several variables. You can find
-information about variables BitBake uses in the
-:doc:`bitbake-user-manual-ref-variables` near the end of this manual. At a
-basic level, it is sufficient to know that BitBake uses the
-:term:`DEPENDS` and
-:term:`RDEPENDS` variables when calculating
-dependencies.
-
-For more information on how BitBake handles dependencies, see the
-:ref:`bitbake-user-manual/bitbake-user-manual-metadata:Dependencies`
-section.
-
-.. _ref-bitbake-tasklist:
-
-The Task List
-=============
-
-Based on the generated list of providers and the dependency information,
-BitBake can now calculate exactly what tasks it needs to run and in what
-order it needs to run them. The
-:ref:`bitbake-user-manual/bitbake-user-manual-execution:executing tasks`
-section has more information on how BitBake chooses which task to
-execute next.
-
-The build now starts with BitBake forking off threads up to the limit
-set in the :term:`BB_NUMBER_THREADS`
-variable. BitBake continues to fork threads as long as there are tasks
-ready to run, those tasks have all their dependencies met, and the
-thread threshold has not been exceeded.
-
-It is worth noting that you can greatly speed up the build time by
-properly setting the ``BB_NUMBER_THREADS`` variable.
-
-As each task completes, a timestamp is written to the directory
-specified by the :term:`STAMP` variable. On subsequent
-runs, BitBake looks in the build directory within ``tmp/stamps`` and
-does not rerun tasks that are already completed unless a timestamp is
-found to be invalid. Currently, invalid timestamps are only considered
-on a per recipe file basis. So, for example, if the configure stamp has
-a timestamp greater than the compile timestamp for a given target, then
-the compile task would rerun. Running the compile task again, however,
-has no effect on other providers that depend on that target.
-
-The exact format of the stamps is partly configurable. In modern
-versions of BitBake, a hash is appended to the stamp so that if the
-configuration changes, the stamp becomes invalid and the task is
-automatically rerun. This hash, or signature used, is governed by the
-signature policy that is configured (see the
-:ref:`bitbake-user-manual/bitbake-user-manual-execution:checksums (signatures)`
-section for information). It is also
-possible to append extra metadata to the stamp using the
-``[stamp-extra-info]`` task flag. For example, OpenEmbedded uses this
-flag to make some tasks machine-specific.
-
-.. note::
-
-   Some tasks are marked as "nostamp" tasks. No timestamp file is
-   created when these tasks are run. Consequently, "nostamp" tasks are
-   always rerun.
-
-For more information on tasks, see the
-:ref:`bitbake-user-manual/bitbake-user-manual-metadata:tasks` section.
-
-Executing Tasks
-===============
-
-Tasks can be either a shell task or a Python task. For shell tasks,
-BitBake writes a shell script to
-``${``\ :term:`T`\ ``}/run.do_taskname.pid`` and then
-executes the script. The generated shell script contains all the
-exported variables, and the shell functions with all variables expanded.
-Output from the shell script goes to the file
-``${T}/log.do_taskname.pid``. Looking at the expanded shell functions in
-the run file and the output in the log files is a useful debugging
-technique.
-
-For Python tasks, BitBake executes the task internally and logs
-information to the controlling terminal. Future versions of BitBake will
-write the functions to files similar to the way shell tasks are handled.
-Logging will be handled in a way similar to shell tasks as well.
-
-The order in which BitBake runs the tasks is controlled by its task
-scheduler. It is possible to configure the scheduler and define custom
-implementations for specific use cases. For more information, see these
-variables that control the behavior:
-
-  :term:`BB_SCHEDULER`
-
-  :term:`BB_SCHEDULERS`
-
-It is possible to have functions run before and after a task's main
-function. This is done using the ``[prefuncs]`` and ``[postfuncs]``
-flags of the task that lists the functions to run.
-
-.. _checksums:
-
-Checksums (Signatures)
-======================
-
-A checksum is a unique signature of a task's inputs. The signature of a
-task can be used to determine if a task needs to be run. Because it is a
-change in a task's inputs that triggers running the task, BitBake needs
-to detect all the inputs to a given task. For shell tasks, this turns
-out to be fairly easy because BitBake generates a "run" shell script for
-each task and it is possible to create a checksum that gives you a good
-idea of when the task's data changes.
-
-To complicate the problem, some things should not be included in the
-checksum. First, there is the actual specific build path of a given task
- the working directory. It does not matter if the working directory
-changes because it should not affect the output for target packages. The
-simplistic approach for excluding the working directory is to set it to
-some fixed value and create the checksum for the "run" script. BitBake
-goes one step better and uses the
-:term:`BB_HASHBASE_WHITELIST` variable
-to define a list of variables that should never be included when
-generating the signatures.
-
-Another problem results from the "run" scripts containing functions that
-might or might not get called. The incremental build solution contains
-code that figures out dependencies between shell functions. This code is
-used to prune the "run" scripts down to the minimum set, thereby
-alleviating this problem and making the "run" scripts much more readable
-as a bonus.
-
-So far we have solutions for shell scripts. What about Python tasks? The
-same approach applies even though these tasks are more difficult. The
-process needs to figure out what variables a Python function accesses
-and what functions it calls. Again, the incremental build solution
-contains code that first figures out the variable and function
-dependencies, and then creates a checksum for the data used as the input
-to the task.
-
-Like the working directory case, situations exist where dependencies
-should be ignored. For these cases, you can instruct the build process
-to ignore a dependency by using a line like the following: ::
-
-  PACKAGE_ARCHS[vardepsexclude] = "MACHINE"
-
-This example ensures that the
-``PACKAGE_ARCHS`` variable does not depend on the value of ``MACHINE``,
-even if it does reference it.
-
-Equally, there are cases where we need to add dependencies BitBake is
-not able to find. You can accomplish this by using a line like the
-following: ::
-
-  PACKAGE_ARCHS[vardeps] = "MACHINE"
-
-This example explicitly
-adds the ``MACHINE`` variable as a dependency for ``PACKAGE_ARCHS``.
-
-Consider a case with in-line Python, for example, where BitBake is not
-able to figure out dependencies. When running in debug mode (i.e. using
-``-DDD``), BitBake produces output when it discovers something for which
-it cannot figure out dependencies.
-
-Thus far, this section has limited discussion to the direct inputs into
-a task. Information based on direct inputs is referred to as the
-"basehash" in the code. However, there is still the question of a task's
-indirect inputs - the things that were already built and present in the
-build directory. The checksum (or signature) for a particular task needs
-to add the hashes of all the tasks on which the particular task depends.
-Choosing which dependencies to add is a policy decision. However, the
-effect is to generate a master checksum that combines the basehash and
-the hashes of the task's dependencies.
-
-At the code level, there are a variety of ways both the basehash and the
-dependent task hashes can be influenced. Within the BitBake
-configuration file, we can give BitBake some extra information to help
-it construct the basehash. The following statement effectively results
-in a list of global variable dependency excludes - variables never
-included in any checksum. This example uses variables from OpenEmbedded
-to help illustrate the concept: ::
-
-   BB_HASHBASE_WHITELIST ?= "TMPDIR FILE PATH PWD BB_TASKHASH BBPATH DL_DIR \
-       SSTATE_DIR THISDIR FILESEXTRAPATHS FILE_DIRNAME HOME LOGNAME SHELL TERM \
-       USER FILESPATH STAGING_DIR_HOST STAGING_DIR_TARGET COREBASE PRSERV_HOST \
-       PRSERV_DUMPDIR PRSERV_DUMPFILE PRSERV_LOCKDOWN PARALLEL_MAKE \
-       CCACHE_DIR EXTERNAL_TOOLCHAIN CCACHE CCACHE_DISABLE LICENSE_PATH SDKPKGSUFFIX"
-
-The previous example excludes the work directory, which is part of
-``TMPDIR``.
-
-The rules for deciding which hashes of dependent tasks to include
-through dependency chains are more complex and are generally
-accomplished with a Python function. The code in
-``meta/lib/oe/sstatesig.py`` shows two examples of this and also
-illustrates how you can insert your own policy into the system if so
-desired. This file defines the two basic signature generators
-OpenEmbedded-Core uses: "OEBasic" and "OEBasicHash". By default, there
-is a dummy "noop" signature handler enabled in BitBake. This means that
-behavior is unchanged from previous versions. ``OE-Core`` uses the
-"OEBasicHash" signature handler by default through this setting in the
-``bitbake.conf`` file: ::
-
-  BB_SIGNATURE_HANDLER ?= "OEBasicHash"
-
-The "OEBasicHash" ``BB_SIGNATURE_HANDLER`` is the same as the "OEBasic"
-version but adds the task hash to the stamp files. This results in any
-metadata change that changes the task hash, automatically causing the
-task to be run again. This removes the need to bump
-:term:`PR` values, and changes to metadata automatically
-ripple across the build.
-
-It is also worth noting that the end result of these signature
-generators is to make some dependency and hash information available to
-the build. This information includes:
-
-  ``BB_BASEHASH_task-``\ *taskname*: The base hashes for each task in the
-   recipe.
-
-  ``BB_BASEHASH_``\ *filename:taskname*: The base hashes for each
-   dependent task.
-
-  ``BBHASHDEPS_``\ *filename:taskname*: The task dependencies for
-   each task.
-
-  ``BB_TASKHASH``: The hash of the currently running task.
-
-It is worth noting that BitBake's "-S" option lets you debug BitBake's
-processing of signatures. The options passed to -S allow different
-debugging modes to be used, either using BitBake's own debug functions
-or possibly those defined in the metadata/signature handler itself. The
-simplest parameter to pass is "none", which causes a set of signature
-information to be written out into ``STAMPS_DIR`` corresponding to the
-targets specified. The other currently available parameter is
-"printdiff", which causes BitBake to try to establish the closest
-signature match it can (e.g. in the sstate cache) and then run
-``bitbake-diffsigs`` over the matches to determine the stamps and delta
-where these two stamp trees diverge.
-
-.. note::
-
-   It is likely that future versions of BitBake will provide other
-   signature handlers triggered through additional "-S" parameters.
-
-You can find more information on checksum metadata in the
-:ref:`bitbake-user-manual/bitbake-user-manual-metadata:task checksums and setscene`
-section.
-
-Setscene
-========
-
-The setscene process enables BitBake to handle "pre-built" artifacts.
-The ability to handle and reuse these artifacts allows BitBake the
-luxury of not having to build something from scratch every time.
-Instead, BitBake can use, when possible, existing build artifacts.
-
-BitBake needs to have reliable data indicating whether or not an
-artifact is compatible. Signatures, described in the previous section,
-provide an ideal way of representing whether an artifact is compatible.
-If a signature is the same, an object can be reused.
-
-If an object can be reused, the problem then becomes how to replace a
-given task or set of tasks with the pre-built artifact. BitBake solves
-the problem with the "setscene" process.
-
-When BitBake is asked to build a given target, before building anything,
-it first asks whether cached information is available for any of the
-targets it's building, or any of the intermediate targets. If cached
-information is available, BitBake uses this information instead of
-running the main tasks.
-
-BitBake first calls the function defined by the
-:term:`BB_HASHCHECK_FUNCTION` variable
-with a list of tasks and corresponding hashes it wants to build. This
-function is designed to be fast and returns a list of the tasks for
-which it believes in can obtain artifacts.
-
-Next, for each of the tasks that were returned as possibilities, BitBake
-executes a setscene version of the task that the possible artifact
-covers. Setscene versions of a task have the string "_setscene" appended
-to the task name. So, for example, the task with the name ``xxx`` has a
-setscene task named ``xxx_setscene``. The setscene version of the task
-executes and provides the necessary artifacts returning either success
-or failure.
-
-As previously mentioned, an artifact can cover more than one task. For
-example, it is pointless to obtain a compiler if you already have the
-compiled binary. To handle this, BitBake calls the
-:term:`BB_SETSCENE_DEPVALID` function for
-each successful setscene task to know whether or not it needs to obtain
-the dependencies of that task.
-
-Finally, after all the setscene tasks have executed, BitBake calls the
-function listed in
-:term:`BB_SETSCENE_VERIFY_FUNCTION2`
-with the list of tasks BitBake thinks has been "covered". The metadata
-can then ensure that this list is correct and can inform BitBake that it
-wants specific tasks to be run regardless of the setscene result.
-
-You can find more information on setscene metadata in the
-:ref:`bitbake-user-manual/bitbake-user-manual-metadata:task checksums and setscene`
-section.
-
-Logging
-=======
-
-In addition to the standard command line option to control how verbose
-builds are when execute, bitbake also supports user defined
-configuration of the `Python
-logging <https://docs.python.org/3/library/logging.html>`__ facilities
-through the :term:`BB_LOGCONFIG` variable. This
-variable defines a json or yaml `logging
-configuration <https://docs.python.org/3/library/logging.config.html>`__
-that will be intelligently merged into the default configuration. The
-logging configuration is merged using the following rules:
-
-  The user defined configuration will completely replace the default
-   configuration if top level key ``bitbake_merge`` is set to the value
-   ``False``. In this case, all other rules are ignored.
-
-  The user configuration must have a top level ``version`` which must
-   match the value of the default configuration.
-
-  Any keys defined in the ``handlers``, ``formatters``, or ``filters``,
-   will be merged into the same section in the default configuration,
-   with the user specified keys taking replacing a default one if there
-   is a conflict. In practice, this means that if both the default
-   configuration and user configuration specify a handler named
-   ``myhandler``, the user defined one will replace the default. To
-   prevent the user from inadvertently replacing a default handler,
-   formatter, or filter, all of the default ones are named with a prefix
-   of "``BitBake.``"
-
-  If a logger is defined by the user with the key ``bitbake_merge`` set
-   to ``False``, that logger will be completely replaced by user
-   configuration. In this case, no other rules will apply to that
-   logger.
-
-  All user defined ``filter`` and ``handlers`` properties for a given
-   logger will be merged with corresponding properties from the default
-   logger. For example, if the user configuration adds a filter called
-   ``myFilter`` to the ``BitBake.SigGen``, and the default configuration
-   adds a filter called ``BitBake.defaultFilter``, both filters will be
-   applied to the logger
-
-As an example, consider the following user logging configuration file
-which logs all Hash Equivalence related messages of VERBOSE or higher to
-a file called ``hashequiv.log`` ::
-
-   {
-       "version": 1,
-       "handlers": {
-           "autobuilderlog": {
-               "class": "logging.FileHandler",
-               "formatter": "logfileFormatter",
-               "level": "DEBUG",
-               "filename": "hashequiv.log",
-               "mode": "w"
-           }
-       },
-       "formatters": {
-               "logfileFormatter": {
-                   "format": "%(name)s: %(levelname)s: %(message)s"
-               }
-       },
-       "loggers": {
-           "BitBake.SigGen.HashEquiv": {
-               "level": "VERBOSE",
-               "handlers": ["autobuilderlog"]
-           },
-           "BitBake.RunQueue.HashEquiv": {
-               "level": "VERBOSE",
-               "handlers": ["autobuilderlog"]
-           }
-       }
-   }

-=====================
-File Download Support
-=====================
-
-|
-
-BitBake's fetch module is a standalone piece of library code that deals
-with the intricacies of downloading source code and files from remote
-systems. Fetching source code is one of the cornerstones of building
-software. As such, this module forms an important part of BitBake.
-
-The current fetch module is called "fetch2" and refers to the fact that
-it is the second major version of the API. The original version is
-obsolete and has been removed from the codebase. Thus, in all cases,
-"fetch" refers to "fetch2" in this manual.
-
-The Download (Fetch)
-====================
-
-BitBake takes several steps when fetching source code or files. The
-fetcher codebase deals with two distinct processes in order: obtaining
-the files from somewhere (cached or otherwise) and then unpacking those
-files into a specific location and perhaps in a specific way. Getting
-and unpacking the files is often optionally followed by patching.
-Patching, however, is not covered by this module.
-
-The code to execute the first part of this process, a fetch, looks
-something like the following: ::
-
-   src_uri = (d.getVar('SRC_URI') or "").split()
-   fetcher = bb.fetch2.Fetch(src_uri, d)
-   fetcher.download()
-
-This code sets up an instance of the fetch class. The instance uses a
-space-separated list of URLs from the :term:`SRC_URI`
-variable and then calls the ``download`` method to download the files.
-
-The instantiation of the fetch class is usually followed by: ::
-
-   rootdir = l.getVar('WORKDIR')
-   fetcher.unpack(rootdir)
-
-This code unpacks the downloaded files to the specified by ``WORKDIR``.
-
-.. note::
-
-   For convenience, the naming in these examples matches the variables
-   used by OpenEmbedded. If you want to see the above code in action,
-   examine the OpenEmbedded class file ``base.bbclass``
-   .
-
-The ``SRC_URI`` and ``WORKDIR`` variables are not hardcoded into the
-fetcher, since those fetcher methods can be (and are) called with
-different variable names. In OpenEmbedded for example, the shared state
-(sstate) code uses the fetch module to fetch the sstate files.
-
-When the ``download()`` method is called, BitBake tries to resolve the
-URLs by looking for source files in a specific search order:
-
-  *Pre-mirror Sites:* BitBake first uses pre-mirrors to try and find
-   source files. These locations are defined using the
-   :term:`PREMIRRORS` variable.
-
-  *Source URI:* If pre-mirrors fail, BitBake uses the original URL (e.g
-   from ``SRC_URI``).
-
-  *Mirror Sites:* If fetch failures occur, BitBake next uses mirror
-   locations as defined by the :term:`MIRRORS` variable.
-
-For each URL passed to the fetcher, the fetcher calls the submodule that
-handles that particular URL type. This behavior can be the source of
-some confusion when you are providing URLs for the ``SRC_URI`` variable.
-Consider the following two URLs: ::
-
-   http://git.yoctoproject.org/git/poky;protocol=git
-   git://git.yoctoproject.org/git/poky;protocol=http
-
-In the former case, the URL is passed to the ``wget`` fetcher, which does not
-understand "git". Therefore, the latter case is the correct form since the Git
-fetcher does know how to use HTTP as a transport.
-
-Here are some examples that show commonly used mirror definitions: ::
-
-   PREMIRRORS ?= "\
-      bzr://.*/.\*  http://somemirror.org/sources/ \\n \
-      cvs://.*/.\*  http://somemirror.org/sources/ \\n \
-      git://.*/.\*  http://somemirror.org/sources/ \\n \
-      hg://.*/.\*   http://somemirror.org/sources/ \\n \
-      osc://.*/.\*  http://somemirror.org/sources/ \\n \
-      p4://.*/.\*   http://somemirror.org/sources/ \\n \
-     svn://.*/.\*   http://somemirror.org/sources/ \\n"
-
-   MIRRORS =+ "\
-      ftp://.*/.\*   http://somemirror.org/sources/ \\n \
-      http://.*/.\*  http://somemirror.org/sources/ \\n \
-      https://.*/.\* http://somemirror.org/sources/ \\n"
-
-It is useful to note that BitBake
-supports cross-URLs. It is possible to mirror a Git repository on an
-HTTP server as a tarball. This is what the ``git://`` mapping in the
-previous example does.
-
-Since network accesses are slow, BitBake maintains a cache of files
-downloaded from the network. Any source files that are not local (i.e.
-downloaded from the Internet) are placed into the download directory,
-which is specified by the :term:`DL_DIR` variable.
-
-File integrity is of key importance for reproducing builds. For
-non-local archive downloads, the fetcher code can verify SHA-256 and MD5
-checksums to ensure the archives have been downloaded correctly. You can
-specify these checksums by using the ``SRC_URI`` variable with the
-appropriate varflags as follows: ::
-
-   SRC_URI[md5sum] = "value"
-   SRC_URI[sha256sum] = "value"
-
-You can also specify the checksums as
-parameters on the ``SRC_URI`` as shown below: ::
-
-  SRC_URI = "http://example.com/foobar.tar.bz2;md5sum=4a8e0f237e961fd7785d19d07fdb994d"
-
-If multiple URIs exist, you can specify the checksums either directly as
-in the previous example, or you can name the URLs. The following syntax
-shows how you name the URIs: ::
-
-   SRC_URI = "http://example.com/foobar.tar.bz2;name=foo"
-   SRC_URI[foo.md5sum] = 4a8e0f237e961fd7785d19d07fdb994d
-
-After a file has been downloaded and
-has had its checksum checked, a ".done" stamp is placed in ``DL_DIR``.
-BitBake uses this stamp during subsequent builds to avoid downloading or
-comparing a checksum for the file again.
-
-.. note::
-
-   It is assumed that local storage is safe from data corruption. If
-   this were not the case, there would be bigger issues to worry about.
-
-If :term:`BB_STRICT_CHECKSUM` is set, any
-download without a checksum triggers an error message. The
-:term:`BB_NO_NETWORK` variable can be used to
-make any attempted network access a fatal error, which is useful for
-checking that mirrors are complete as well as other things.
-
-.. _bb-the-unpack:
-
-The Unpack
-==========
-
-The unpack process usually immediately follows the download. For all
-URLs except Git URLs, BitBake uses the common ``unpack`` method.
-
-A number of parameters exist that you can specify within the URL to
-govern the behavior of the unpack stage:
-
-  *unpack:* Controls whether the URL components are unpacked. If set to
-   "1", which is the default, the components are unpacked. If set to
-   "0", the unpack stage leaves the file alone. This parameter is useful
-   when you want an archive to be copied in and not be unpacked.
-
-  *dos:* Applies to ``.zip`` and ``.jar`` files and specifies whether
-   to use DOS line ending conversion on text files.
-
-  *basepath:* Instructs the unpack stage to strip the specified
-   directories from the source path when unpacking.
-
-  *subdir:* Unpacks the specific URL to the specified subdirectory
-   within the root directory.
-
-The unpack call automatically decompresses and extracts files with ".Z",
-".z", ".gz", ".xz", ".zip", ".jar", ".ipk", ".rpm". ".srpm", ".deb" and
-".bz2" extensions as well as various combinations of tarball extensions.
-
-As mentioned, the Git fetcher has its own unpack method that is
-optimized to work with Git trees. Basically, this method works by
-cloning the tree into the final directory. The process is completed
-using references so that there is only one central copy of the Git
-metadata needed.
-
-.. _bb-fetchers:
-
-Fetchers
-========
-
-As mentioned earlier, the URL prefix determines which fetcher submodule
-BitBake uses. Each submodule can support different URL parameters, which
-are described in the following sections.
-
-.. _local-file-fetcher:
-
-Local file fetcher (``file://``)
--------------------------------
-
-This submodule handles URLs that begin with ``file://``. The filename
-you specify within the URL can be either an absolute or relative path to
-a file. If the filename is relative, the contents of the
-:term:`FILESPATH` variable is used in the same way
-``PATH`` is used to find executables. If the file cannot be found, it is
-assumed that it is available in :term:`DL_DIR` by the
-time the ``download()`` method is called.
-
-If you specify a directory, the entire directory is unpacked.
-
-Here are a couple of example URLs, the first relative and the second
-absolute: ::
-
-   SRC_URI = "file://relativefile.patch"
-   SRC_URI = "file:///Users/ich/very_important_software"
-
-.. _http-ftp-fetcher:
-
-HTTP/FTP wget fetcher (``http://``, ``ftp://``, ``https://``)
-------------------------------------------------------------
-
-This fetcher obtains files from web and FTP servers. Internally, the
-fetcher uses the wget utility.
-
-The executable and parameters used are specified by the
-``FETCHCMD_wget`` variable, which defaults to sensible values. The
-fetcher supports a parameter "downloadfilename" that allows the name of
-the downloaded file to be specified. Specifying the name of the
-downloaded file is useful for avoiding collisions in
-:term:`DL_DIR` when dealing with multiple files that
-have the same name.
-
-Some example URLs are as follows: ::
-
-   SRC_URI = "http://oe.handhelds.org/not_there.aac"
-   SRC_URI = "ftp://oe.handhelds.org/not_there_as_well.aac"
-   SRC_URI = "ftp://you@oe.handhelds.org/home/you/secret.plan"
-
-.. note::
-
-   Because URL parameters are delimited by semi-colons, this can
-   introduce ambiguity when parsing URLs that also contain semi-colons,
-   for example:
-   ::
-
-           SRC_URI = "http://abc123.org/git/?p=gcc/gcc.git;a=snapshot;h=a5dd47"
-
-
-   Such URLs should should be modified by replacing semi-colons with '&'
-   characters:
-   ::
-
-           SRC_URI = "http://abc123.org/git/?p=gcc/gcc.git&a=snapshot&h=a5dd47"
-
-
-   In most cases this should work. Treating semi-colons and '&' in
-   queries identically is recommended by the World Wide Web Consortium
-   (W3C). Note that due to the nature of the URL, you may have to
-   specify the name of the downloaded file as well:
-   ::
-
-           SRC_URI = "http://abc123.org/git/?p=gcc/gcc.git&a=snapshot&h=a5dd47;downloadfilename=myfile.bz2"
-
-
-.. _cvs-fetcher:
-
-CVS fetcher (``(cvs://``)
-------------------------
-
-This submodule handles checking out files from the CVS version control
-system. You can configure it using a number of different variables:
-
-  :term:`FETCHCMD_cvs <FETCHCMD>`: The name of the executable to use when running
-   the ``cvs`` command. This name is usually "cvs".
-
-  :term:`SRCDATE`: The date to use when fetching the CVS source code. A
-   special value of "now" causes the checkout to be updated on every
-   build.
-
-  :term:`CVSDIR`: Specifies where a temporary
-   checkout is saved. The location is often ``DL_DIR/cvs``.
-
-  CVS_PROXY_HOST: The name to use as a "proxy=" parameter to the
-   ``cvs`` command.
-
-  CVS_PROXY_PORT: The port number to use as a "proxyport="
-   parameter to the ``cvs`` command.
-
-As well as the standard username and password URL syntax, you can also
-configure the fetcher with various URL parameters:
-
-The supported parameters are as follows:
-
-  *"method":* The protocol over which to communicate with the CVS
-   server. By default, this protocol is "pserver". If "method" is set to
-   "ext", BitBake examines the "rsh" parameter and sets ``CVS_RSH``. You
-   can use "dir" for local directories.
-
-  *"module":* Specifies the module to check out. You must supply this
-   parameter.
-
-  *"tag":* Describes which CVS TAG should be used for the checkout. By
-   default, the TAG is empty.
-
-  *"date":* Specifies a date. If no "date" is specified, the
-   :term:`SRCDATE` of the configuration is used to
-   checkout a specific date. The special value of "now" causes the
-   checkout to be updated on every build.
-
-  *"localdir":* Used to rename the module. Effectively, you are
-   renaming the output directory to which the module is unpacked. You
-   are forcing the module into a special directory relative to
-   :term:`CVSDIR`.
-
-  *"rsh":* Used in conjunction with the "method" parameter.
-
-  *"scmdata":* Causes the CVS metadata to be maintained in the tarball
-   the fetcher creates when set to "keep". The tarball is expanded into
-   the work directory. By default, the CVS metadata is removed.
-
-  *"fullpath":* Controls whether the resulting checkout is at the
-   module level, which is the default, or is at deeper paths.
-
-  *"norecurse":* Causes the fetcher to only checkout the specified
-   directory with no recurse into any subdirectories.
-
-  *"port":* The port to which the CVS server connects.
-
-Some example URLs are as follows: ::
-
-   SRC_URI = "cvs://CVSROOT;module=mymodule;tag=some-version;method=ext"
-   SRC_URI = "cvs://CVSROOT;module=mymodule;date=20060126;localdir=usethat"
-
-.. _svn-fetcher:
-
-Subversion (SVN) Fetcher (``svn://``)
-------------------------------------
-
-This fetcher submodule fetches code from the Subversion source control
-system. The executable used is specified by ``FETCHCMD_svn``, which
-defaults to "svn". The fetcher's temporary working directory is set by
-:term:`SVNDIR`, which is usually ``DL_DIR/svn``.
-
-The supported parameters are as follows:
-
-  *"module":* The name of the svn module to checkout. You must provide
-   this parameter. You can think of this parameter as the top-level
-   directory of the repository data you want.
-
-  *"path_spec":* A specific directory in which to checkout the
-   specified svn module.
-
-  *"protocol":* The protocol to use, which defaults to "svn". If
-   "protocol" is set to "svn+ssh", the "ssh" parameter is also used.
-
-  *"rev":* The revision of the source code to checkout.
-
-  *"scmdata":* Causes the ".svn" directories to be available during
-   compile-time when set to "keep". By default, these directories are
-   removed.
-
-  *"ssh":* An optional parameter used when "protocol" is set to
-   "svn+ssh". You can use this parameter to specify the ssh program used
-   by svn.
-
-  *"transportuser":* When required, sets the username for the
-   transport. By default, this parameter is empty. The transport
-   username is different than the username used in the main URL, which
-   is passed to the subversion command.
-
-Following are three examples using svn: ::
-
-   SRC_URI = "svn://myrepos/proj1;module=vip;protocol=http;rev=667"
-   SRC_URI = "svn://myrepos/proj1;module=opie;protocol=svn+ssh"
-   SRC_URI = "svn://myrepos/proj1;module=trunk;protocol=http;path_spec=${MY_DIR}/proj1"
-
-.. _git-fetcher:
-
-Git Fetcher (``git://``)
------------------------
-
-This fetcher submodule fetches code from the Git source control system.
-The fetcher works by creating a bare clone of the remote into
-:term:`GITDIR`, which is usually ``DL_DIR/git2``. This
-bare clone is then cloned into the work directory during the unpack
-stage when a specific tree is checked out. This is done using alternates
-and by reference to minimize the amount of duplicate data on the disk
-and make the unpack process fast. The executable used can be set with
-``FETCHCMD_git``.
-
-This fetcher supports the following parameters:
-
-  *"protocol":* The protocol used to fetch the files. The default is
-   "git" when a hostname is set. If a hostname is not set, the Git
-   protocol is "file". You can also use "http", "https", "ssh" and
-   "rsync".
-
-  *"nocheckout":* Tells the fetcher to not checkout source code when
-   unpacking when set to "1". Set this option for the URL where there is
-   a custom routine to checkout code. The default is "0".
-
-  *"rebaseable":* Indicates that the upstream Git repository can be
-   rebased. You should set this parameter to "1" if revisions can become
-   detached from branches. In this case, the source mirror tarball is
-   done per revision, which has a loss of efficiency. Rebasing the
-   upstream Git repository could cause the current revision to disappear
-   from the upstream repository. This option reminds the fetcher to
-   preserve the local cache carefully for future use. The default value
-   for this parameter is "0".
-
-  *"nobranch":* Tells the fetcher to not check the SHA validation for
-   the branch when set to "1". The default is "0". Set this option for
-   the recipe that refers to the commit that is valid for any namespace
-   (branch, tag, ...) instead of the branch.
-
-  *"bareclone":* Tells the fetcher to clone a bare clone into the
-   destination directory without checking out a working tree. Only the
-   raw Git metadata is provided. This parameter implies the "nocheckout"
-   parameter as well.
-
-  *"branch":* The branch(es) of the Git tree to clone. If unset, this
-   is assumed to be "master". The number of branch parameters much match
-   the number of name parameters.
-
-  *"rev":* The revision to use for the checkout. The default is
-   "master".
-
-  *"tag":* Specifies a tag to use for the checkout. To correctly
-   resolve tags, BitBake must access the network. For that reason, tags
-   are often not used. As far as Git is concerned, the "tag" parameter
-   behaves effectively the same as the "rev" parameter.
-
-  *"subpath":* Limits the checkout to a specific subpath of the tree.
-   By default, the whole tree is checked out.
-
-  *"destsuffix":* The name of the path in which to place the checkout.
-   By default, the path is ``git/``.
-
-  *"usehead":* Enables local ``git://`` URLs to use the current branch
-   HEAD as the revision for use with ``AUTOREV``. The "usehead"
-   parameter implies no branch and only works when the transfer protocol
-   is ``file://``.
-
-Here are some example URLs: ::
-
-   SRC_URI = "git://git.oe.handhelds.org/git/vip.git;tag=version-1"
-   SRC_URI = "git://git.oe.handhelds.org/git/vip.git;protocol=http"
-
-.. _gitsm-fetcher:
-
-Git Submodule Fetcher (``gitsm://``)
------------------------------------
-
-This fetcher submodule inherits from the :ref:`Git
-fetcher<bitbake-user-manual/bitbake-user-manual-fetching:git fetcher
-(\`\`git://\`\`)>` and extends that fetcher's behavior by fetching a
-repository's submodules. :term:`SRC_URI` is passed to the Git fetcher as
-described in the :ref:`bitbake-user-manual/bitbake-user-manual-fetching:git
-fetcher (\`\`git://\`\`)` section.
-
-.. note::
-
-   You must clean a recipe when switching between '``git://``' and
-   '``gitsm://``' URLs.
-
-   The Git Submodules fetcher is not a complete fetcher implementation.
-   The fetcher has known issues where it does not use the normal source
-   mirroring infrastructure properly. Further, the submodule sources it
-   fetches are not visible to the licensing and source archiving
-   infrastructures.
-
-.. _clearcase-fetcher:
-
-ClearCase Fetcher (``ccrc://``)
-------------------------------
-
-This fetcher submodule fetches code from a
-`ClearCase <http://en.wikipedia.org/wiki/Rational_ClearCase>`__
-repository.
-
-To use this fetcher, make sure your recipe has proper
-:term:`SRC_URI`, :term:`SRCREV`, and
-:term:`PV` settings. Here is an example: ::
-
-   SRC_URI = "ccrc://cc.example.org/ccrc;vob=/example_vob;module=/example_module"
-   SRCREV = "EXAMPLE_CLEARCASE_TAG"
-   PV = "${@d.getVar("SRCREV", False).replace("/", "+")}"
-
-The fetcher uses the ``rcleartool`` or
-``cleartool`` remote client, depending on which one is available.
-
-Following are options for the ``SRC_URI`` statement:
-
-  *vob*: The name, which must include the prepending "/" character,
-   of the ClearCase VOB. This option is required.
-
-  *module*: The module, which must include the prepending "/"
-   character, in the selected VOB.
-
-   .. note::
-
-      The module and vob options are combined to create the load rule in the
-      view config spec. As an example, consider the vob and module values from
-      the SRC_URI statement at the start of this section. Combining those values
-      results in the following: ::
-
-         load /example_vob/example_module
-
-  *proto*: The protocol, which can be either ``http`` or ``https``.
-
-By default, the fetcher creates a configuration specification. If you
-want this specification written to an area other than the default, use
-the ``CCASE_CUSTOM_CONFIG_SPEC`` variable in your recipe to define where
-the specification is written.
-
-.. note::
-
-   the SRCREV loses its functionality if you specify this variable. However,
-   SRCREV is still used to label the archive after a fetch even though it does
-   not define what is fetched.
-
-Here are a couple of other behaviors worth mentioning:
-
-  When using ``cleartool``, the login of ``cleartool`` is handled by
-   the system. The login require no special steps.
-
-  In order to use ``rcleartool`` with authenticated users, an
-   "rcleartool login" is necessary before using the fetcher.
-
-.. _perforce-fetcher:
-
-Perforce Fetcher (``p4://``)
----------------------------
-
-This fetcher submodule fetches code from the
-`Perforce <https://www.perforce.com/>`__ source control system. The
-executable used is specified by ``FETCHCMD_p4``, which defaults to "p4".
-The fetcher's temporary working directory is set by
-:term:`P4DIR`, which defaults to "DL_DIR/p4".
-The fetcher does not make use of a perforce client, instead it
-relies on ``p4 files`` to retrieve a list of
-files and ``p4 print`` to transfer the content
-of those files locally.
-
-To use this fetcher, make sure your recipe has proper
-:term:`SRC_URI`, :term:`SRCREV`, and
-:term:`PV` values. The p4 executable is able to use the
-config file defined by your system's ``P4CONFIG`` environment variable
-in order to define the Perforce server URL and port, username, and
-password if you do not wish to keep those values in a recipe itself. If
-you choose not to use ``P4CONFIG``, or to explicitly set variables that
-``P4CONFIG`` can contain, you can specify the ``P4PORT`` value, which is
-the server's URL and port number, and you can specify a username and
-password directly in your recipe within ``SRC_URI``.
-
-Here is an example that relies on ``P4CONFIG`` to specify the server URL
-and port, username, and password, and fetches the Head Revision: ::
-
-   SRC_URI = "p4://example-depot/main/source/..."
-   SRCREV = "${AUTOREV}"
-   PV = "p4-${SRCPV}"
-   S = "${WORKDIR}/p4"
-
-Here is an example that specifies the server URL and port, username, and
-password, and fetches a Revision based on a Label: ::
-
-   P4PORT = "tcp:p4server.example.net:1666"
-   SRC_URI = "p4://user:passwd@example-depot/main/source/..."
-   SRCREV = "release-1.0"
-   PV = "p4-${SRCPV}"
-   S = "${WORKDIR}/p4"
-
-.. note::
-
-   You should always set S to "${WORKDIR}/p4" in your recipe.
-
-.. _repo-fetcher:
-
-Repo Fetcher (``repo://``)
--------------------------
-
-This fetcher submodule fetches code from ``google-repo`` source control
-system. The fetcher works by initiating and syncing sources of the
-repository into :term:`REPODIR`, which is usually
-``${DL_DIR}/repo``.
-
-This fetcher supports the following parameters:
-
-  *"protocol":* Protocol to fetch the repository manifest (default:
-   git).
-
-  *"branch":* Branch or tag of repository to get (default: master).
-
-  *"manifest":* Name of the manifest file (default: ``default.xml``).
-
-Here are some example URLs: ::
-
-   SRC_URI = "repo://REPOROOT;protocol=git;branch=some_branch;manifest=my_manifest.xml"
-   SRC_URI = "repo://REPOROOT;protocol=file;branch=some_branch;manifest=my_manifest.xml"
-
-Other Fetchers
--------------
-
-Fetch submodules also exist for the following:
-
-  Bazaar (``bzr://``)
-
-  Mercurial (``hg://``)
-
-  npm (``npm://``)
-
-  OSC (``osc://``)
-
-  Secure FTP (``sftp://``)
-
-  Secure Shell (``ssh://``)
-
-  Trees using Git Annex (``gitannex://``)
-
-No documentation currently exists for these lesser used fetcher
-submodules. However, you might find the code helpful and readable.
-
-Auto Revisions
-==============
-
-We need to document ``AUTOREV`` and ``SRCREV_FORMAT`` here.

-Hello World Example
-===================
-
-BitBake Hello World
-===================
-
-The simplest example commonly used to demonstrate any new programming
-language or tool is the "`Hello
-World <http://en.wikipedia.org/wiki/Hello_world_program>`__" example.
-This appendix demonstrates, in tutorial form, Hello World within the
-context of BitBake. The tutorial describes how to create a new project
-and the applicable metadata files necessary to allow BitBake to build
-it.
-
-Obtaining BitBake
-=================
-
-See the :ref:`bitbake-user-manual/bitbake-user-manual-hello:obtaining bitbake` section for
-information on how to obtain BitBake. Once you have the source code on
-your machine, the BitBake directory appears as follows: ::
-
-   $ ls -al
-   total 100
-   drwxrwxr-x. 9 wmat wmat  4096 Jan 31 13:44 .
-   drwxrwxr-x. 3 wmat wmat  4096 Feb  4 10:45 ..
-   -rw-rw-r--. 1 wmat wmat   365 Nov 26 04:55 AUTHORS
-   drwxrwxr-x. 2 wmat wmat  4096 Nov 26 04:55 bin
-   drwxrwxr-x. 4 wmat wmat  4096 Jan 31 13:44 build
-   -rw-rw-r--. 1 wmat wmat 16501 Nov 26 04:55 ChangeLog

-   -rw-rw-r--. 1 wmat wmat  2887 Nov 26 04:55 TODO
-
-At this point, you should have BitBake cloned to a directory that
-matches the previous listing except for dates and user names.
-
-Setting Up the BitBake Environment
-==================================
-
-First, you need to be sure that you can run BitBake. Set your working
-directory to where your local BitBake files are and run the following
-command: ::
-
-  $ ./bin/bitbake --version
-  BitBake Build Tool Core version 1.23.0, bitbake version 1.23.0
-
-The console output tells you what version
-you are running.
-
-The recommended method to run BitBake is from a directory of your
-choice. To be able to run BitBake from any directory, you need to add
-the executable binary to your binary to your shell's environment
-``PATH`` variable. First, look at your current ``PATH`` variable by
-entering the following: ::
-
-  $ echo $PATH
-
-Next, add the directory location
-for the BitBake binary to the ``PATH``. Here is an example that adds the
-``/home/scott-lenovo/bitbake/bin`` directory to the front of the
-``PATH`` variable: ::
-
-  $ export PATH=/home/scott-lenovo/bitbake/bin:$PATH
-
-You should now be able to enter the ``bitbake`` command from the command
-line while working from any directory.
-
-The Hello World Example
-=======================
-
-The overall goal of this exercise is to build a complete "Hello World"
-example utilizing task and layer concepts. Because this is how modern
-projects such as OpenEmbedded and the Yocto Project utilize BitBake, the
-example provides an excellent starting point for understanding BitBake.
-
-To help you understand how to use BitBake to build targets, the example
-starts with nothing but the ``bitbake`` command, which causes BitBake to
-fail and report problems. The example progresses by adding pieces to the
-build to eventually conclude with a working, minimal "Hello World"
-example.
-
-While every attempt is made to explain what is happening during the
-example, the descriptions cannot cover everything. You can find further
-information throughout this manual. Also, you can actively participate
-in the :oe_lists:`/g/bitbake-devel`
-discussion mailing list about the BitBake build tool.
-
-.. note::
-
-   This example was inspired by and drew heavily from
-   `Mailing List post - The BitBake equivalent of "Hello, World!"
-   <http://www.mail-archive.com/yocto@yoctoproject.org/msg09379.html>`_.
-
-As stated earlier, the goal of this example is to eventually compile
-"Hello World". However, it is unknown what BitBake needs and what you
-have to provide in order to achieve that goal. Recall that BitBake
-utilizes three types of metadata files:
-:ref:`bitbake-user-manual/bitbake-user-manual-intro:configuration files`,
-:ref:`bitbake-user-manual/bitbake-user-manual-intro:classes`, and
-:ref:`bitbake-user-manual/bitbake-user-manual-intro:recipes`.
-But where do they go? How does BitBake find
-them? BitBake's error messaging helps you answer these types of
-questions and helps you better understand exactly what is going on.
-
-Following is the complete "Hello World" example.
-
-#.  **Create a Project Directory:** First, set up a directory for the
-    "Hello World" project. Here is how you can do so in your home
-    directory: ::
-
-      $ mkdir ~/hello
-      $ cd ~/hello
-
-    This is the directory that
-    BitBake will use to do all of its work. You can use this directory
-    to keep all the metafiles needed by BitBake. Having a project
-    directory is a good way to isolate your project.
-
-#.  **Run BitBake:** At this point, you have nothing but a project
-    directory. Run the ``bitbake`` command and see what it does: ::
-
-       $ bitbake
-       The BBPATH variable is not set and bitbake did not
-       find a conf/bblayers.conf file in the expected location.
-       Maybe you accidentally invoked bitbake from the wrong directory?
-       DEBUG: Removed the following variables from the environment:
-       GNOME_DESKTOP_SESSION_ID, XDG_CURRENT_DESKTOP,
-       GNOME_KEYRING_CONTROL, DISPLAY, SSH_AGENT_PID, LANG, no_proxy,
-       XDG_SESSION_PATH, XAUTHORITY, SESSION_MANAGER, SHLVL,
-       MANDATORY_PATH, COMPIZ_CONFIG_PROFILE, WINDOWID, EDITOR,
-       GPG_AGENT_INFO, SSH_AUTH_SOCK, GDMSESSION, GNOME_KEYRING_PID,
-       XDG_SEAT_PATH, XDG_CONFIG_DIRS, LESSOPEN, DBUS_SESSION_BUS_ADDRESS,
-       _, XDG_SESSION_COOKIE, DESKTOP_SESSION, LESSCLOSE, DEFAULTS_PATH,
-       UBUNTU_MENUPROXY, OLDPWD, XDG_DATA_DIRS, COLORTERM, LS_COLORS
-
-    The majority of this output is specific to environment variables that
-    are not directly relevant to BitBake. However, the very first
-    message regarding the ``BBPATH`` variable and the
-    ``conf/bblayers.conf`` file is relevant.
-
-    When you run BitBake, it begins looking for metadata files. The
-    :term:`BBPATH` variable is what tells BitBake where
-    to look for those files. ``BBPATH`` is not set and you need to set
-    it. Without ``BBPATH``, BitBake cannot find any configuration files
-    (``.conf``) or recipe files (``.bb``) at all. BitBake also cannot
-    find the ``bitbake.conf`` file.
-
-#.  **Setting BBPATH:** For this example, you can set ``BBPATH`` in
-    the same manner that you set ``PATH`` earlier in the appendix. You
-    should realize, though, that it is much more flexible to set the
-    ``BBPATH`` variable up in a configuration file for each project.
-
-    From your shell, enter the following commands to set and export the
-    ``BBPATH`` variable: ::
-
-      $ BBPATH="projectdirectory"
-      $ export BBPATH
-
-    Use your actual project directory in the command. BitBake uses that
-    directory to find the metadata it needs for your project.
-
-    .. note::
-
-       When specifying your project directory, do not use the tilde
-       ("~") character as BitBake does not expand that character as the
-       shell would.
-
-#.  **Run BitBake:** Now that you have ``BBPATH`` defined, run the
-    ``bitbake`` command again: ::
-
-       $ bitbake
-       ERROR: Traceback (most recent call last):
-         File "/home/scott-lenovo/bitbake/lib/bb/cookerdata.py", line 163, in wrapped
-           return func(fn, *args)
-         File "/home/scott-lenovo/bitbake/lib/bb/cookerdata.py", line 173, in parse_config_file
-           return bb.parse.handle(fn, data, include)
-         File "/home/scott-lenovo/bitbake/lib/bb/parse/__init__.py", line 99, in handle
-           return h['handle'](fn, data, include)
-         File "/home/scott-lenovo/bitbake/lib/bb/parse/parse_py/ConfHandler.py", line 120, in handle
-           abs_fn = resolve_file(fn, data)
-         File "/home/scott-lenovo/bitbake/lib/bb/parse/__init__.py", line 117, in resolve_file
-           raise IOError("file %s not found in %s" % (fn, bbpath))
-       IOError: file conf/bitbake.conf not found in /home/scott-lenovo/hello
-
-       ERROR: Unable to parse conf/bitbake.conf: file conf/bitbake.conf not found in /home/scott-lenovo/hello
-
-    This sample output shows that BitBake could not find the
-    ``conf/bitbake.conf`` file in the project directory. This file is
-    the first thing BitBake must find in order to build a target. And,
-    since the project directory for this example is empty, you need to
-    provide a ``conf/bitbake.conf`` file.
-
-#.  **Creating conf/bitbake.conf:** The ``conf/bitbake.conf`` includes
-    a number of configuration variables BitBake uses for metadata and
-    recipe files. For this example, you need to create the file in your
-    project directory and define some key BitBake variables. For more
-    information on the ``bitbake.conf`` file, see
-    http://git.openembedded.org/bitbake/tree/conf/bitbake.conf.
-
-    Use the following commands to create the ``conf`` directory in the
-    project directory: ::
-
-      $ mkdir conf
-
-    From within the ``conf`` directory,
-    use some editor to create the ``bitbake.conf`` so that it contains
-    the following: ::
-
-       PN  = "${@bb.parse.BBHandler.vars_from_file(d.getVar('FILE', False),d)[0] or 'defaultpkgname'}"
-
-       TMPDIR  = "${TOPDIR}/tmp"
-       CACHE   = "${TMPDIR}/cache"
-       STAMP   = "${TMPDIR}/${PN}/stamps"
-       T       = "${TMPDIR}/${PN}/work"
-       B       = "${TMPDIR}/${PN}"
-
-    .. note::
-
-       Without a value for PN , the variables STAMP , T , and B , prevent more
-       than one recipe from working. You can fix this by either setting PN to
-       have a value similar to what OpenEmbedded and BitBake use in the default
-       bitbake.conf file (see previous example). Or, by manually updating each
-       recipe to set PN . You will also need to include PN as part of the STAMP
-       , T , and B variable definitions in the local.conf file.
-
-    The ``TMPDIR`` variable establishes a directory that BitBake uses
-    for build output and intermediate files other than the cached
-    information used by the
-    :ref:`bitbake-user-manual/bitbake-user-manual-execution:setscene`
-    process. Here, the ``TMPDIR`` directory is set to ``hello/tmp``.
-
-    .. tip::
-
-       You can always safely delete the tmp directory in order to rebuild a
-       BitBake target. The build process creates the directory for you when you
-       run BitBake.
-
-    For information about each of the other variables defined in this
-    example, check :term:`PN`, :term:`TOPDIR`, :term:`CACHE`, :term:`STAMP`,
-    :term:`T` or :term:`B` to take you to the definitions in the
-    glossary.
-
-#.  **Run BitBake:** After making sure that the ``conf/bitbake.conf`` file
-    exists, you can run the ``bitbake`` command again: ::
-
-       $ bitbake
-       ERROR: Traceback (most recent call last):
-         File "/home/scott-lenovo/bitbake/lib/bb/cookerdata.py", line 163, in wrapped
-           return func(fn, *args)
-         File "/home/scott-lenovo/bitbake/lib/bb/cookerdata.py", line 177, in _inherit
-           bb.parse.BBHandler.inherit(bbclass, "configuration INHERITs", 0, data)
-         File "/home/scott-lenovo/bitbake/lib/bb/parse/parse_py/BBHandler.py", line 92, in inherit
-           include(fn, file, lineno, d, "inherit")
-         File "/home/scott-lenovo/bitbake/lib/bb/parse/parse_py/ConfHandler.py", line 100, in include
-           raise ParseError("Could not %(error_out)s file %(fn)s" % vars(), oldfn, lineno)
-       ParseError: ParseError in configuration INHERITs: Could not inherit file classes/base.bbclass
-
-       ERROR: Unable to parse base: ParseError in configuration INHERITs: Could not inherit file classes/base.bbclass
-
-    In the sample output,
-    BitBake could not find the ``classes/base.bbclass`` file. You need
-    to create that file next.
-
-#.  **Creating classes/base.bbclass:** BitBake uses class files to
-    provide common code and functionality. The minimally required class
-    for BitBake is the ``classes/base.bbclass`` file. The ``base`` class
-    is implicitly inherited by every recipe. BitBake looks for the class
-    in the ``classes`` directory of the project (i.e ``hello/classes``
-    in this example).
-
-    Create the ``classes`` directory as follows: ::
-
-      $ cd $HOME/hello
-      $ mkdir classes
-
-    Move to the ``classes`` directory and then create the
-    ``base.bbclass`` file by inserting this single line: addtask build
-    The minimal task that BitBake runs is the ``do_build`` task. This is
-    all the example needs in order to build the project. Of course, the
-    ``base.bbclass`` can have much more depending on which build
-    environments BitBake is supporting.
-
-#.  **Run BitBake:** After making sure that the ``classes/base.bbclass``
-    file exists, you can run the ``bitbake`` command again: ::
-
-       $ bitbake
-       Nothing to do. Use 'bitbake world' to build everything, or run 'bitbake --help' for usage information.
-
-    BitBake is finally reporting
-    no errors. However, you can see that it really does not have
-    anything to do. You need to create a recipe that gives BitBake
-    something to do.
-
-#.  **Creating a Layer:** While it is not really necessary for such a
-    small example, it is good practice to create a layer in which to
-    keep your code separate from the general metadata used by BitBake.
-    Thus, this example creates and uses a layer called "mylayer".
-
-    .. note::
-
-       You can find additional information on layers in the
-       ":ref:`bitbake-user-manual/bitbake-user-manual-intro:Layers`" section.
-
-    Minimally, you need a recipe file and a layer configuration file in
-    your layer. The configuration file needs to be in the ``conf``
-    directory inside the layer. Use these commands to set up the layer
-    and the ``conf`` directory: ::
-
-       $ cd $HOME
-       $ mkdir mylayer
-       $ cd mylayer
-       $ mkdir conf
-
-    Move to the ``conf`` directory and create a ``layer.conf`` file that has the
-    following: ::
-
-      BBPATH .= ":${LAYERDIR}"
-      BBFILES += "${LAYERDIR}/\*.bb"
-      BBFILE_COLLECTIONS += "mylayer"
-     `BBFILE_PATTERN_mylayer := "^${LAYERDIR_RE}/"
-
-    For information on these variables, click on :term:`BBFILES`,
-    :term:`LAYERDIR`, :term:`BBFILE_COLLECTIONS` or :term:`BBFILE_PATTERN_mylayer <BBFILE_PATTERN>`
-    to go to the definitions in the glossary.
-
-    You need to create the recipe file next. Inside your layer at the
-    top-level, use an editor and create a recipe file named
-    ``printhello.bb`` that has the following: ::
-
-       DESCRIPTION = "Prints Hello World"
-       PN = 'printhello'
-       PV = '1'
-
-       python do_build() {
-          bb.plain("********************");
-          bb.plain("*                  *");
-          bb.plain("*  Hello, World!   *");
-          bb.plain("*                  *");
-          bb.plain("********************");
-       }
-
-    The recipe file simply provides
-    a description of the recipe, the name, version, and the ``do_build``
-    task, which prints out "Hello World" to the console. For more
-    information on :term:`DESCRIPTION`, :term:`PN` or :term:`PV`
-    follow the links to the glossary.

-#. **Run BitBake With a Target:** Now that a BitBake target exists, run
-    the command and provide that target: ::
-
-      $ cd $HOME/hello
-      $ bitbake printhello
-      ERROR: no recipe files to build, check your BBPATH and BBFILES?
-
-      Summary: There was 1 ERROR message shown, returning a non-zero exit code.
-
-    We have created the layer with the recipe and
-    the layer configuration file but it still seems that BitBake cannot
-    find the recipe. BitBake needs a ``conf/bblayers.conf`` that lists
-    the layers for the project. Without this file, BitBake cannot find
-    the recipe.
-
-#. **Creating conf/bblayers.conf:** BitBake uses the
-    ``conf/bblayers.conf`` file to locate layers needed for the project.
-    This file must reside in the ``conf`` directory of the project (i.e.
-    ``hello/conf`` for this example).
-
-    Set your working directory to the ``hello/conf`` directory and then
-    create the ``bblayers.conf`` file so that it contains the following: ::
-
-       BBLAYERS ?= " \
-           /home/<you>/mylayer \
-       "
-
-    You need to provide your own information for ``you`` in the file.
-
-#. **Run BitBake With a Target:** Now that you have supplied the
-    ``bblayers.conf`` file, run the ``bitbake`` command and provide the
-    target: ::

-       does not need to be re-run. If you delete the tmp directory or run

-
-Welcome to the BitBake User Manual. This manual provides information on
-the BitBake tool. The information attempts to be as independent as
-possible regarding systems that use BitBake, such as OpenEmbedded and
-the Yocto Project. In some cases, scenarios or examples within the
-context of a build system are used in the manual to help with
-understanding. For these cases, the manual clearly states the context.
-
-.. _intro:
-
-Introduction
-============
-
-Fundamentally, BitBake is a generic task execution engine that allows
-shell and Python tasks to be run efficiently and in parallel while
-working within complex inter-task dependency constraints. One of
-BitBake's main users, OpenEmbedded, takes this core and builds embedded
-Linux software stacks using a task-oriented approach.
-
-Conceptually, BitBake is similar to GNU Make in some regards but has
-significant differences:
-
-  BitBake executes tasks according to provided metadata that builds up
-   the tasks. Metadata is stored in recipe (``.bb``) and related recipe
-   "append" (``.bbappend``) files, configuration (``.conf``) and
-   underlying include (``.inc``) files, and in class (``.bbclass``)
-   files. The metadata provides BitBake with instructions on what tasks
-   to run and the dependencies between those tasks.
-
-  BitBake includes a fetcher library for obtaining source code from
-   various places such as local files, source control systems, or
-   websites.
-
-  The instructions for each unit to be built (e.g. a piece of software)
-   are known as "recipe" files and contain all the information about the
-   unit (dependencies, source file locations, checksums, description and
-   so on).
-
-  BitBake includes a client/server abstraction and can be used from a
-   command line or used as a service over XML-RPC and has several
-   different user interfaces.
-
-History and Goals
-=================
-
-BitBake was originally a part of the OpenEmbedded project. It was
-inspired by the Portage package management system used by the Gentoo
-Linux distribution. On December 7, 2004, OpenEmbedded project team
-member Chris Larson split the project into two distinct pieces:
-
-  BitBake, a generic task executor
-
-  OpenEmbedded, a metadata set utilized by BitBake
-
-Today, BitBake is the primary basis of the
-`OpenEmbedded <http://www.openembedded.org/>`__ project, which is being
-used to build and maintain Linux distributions such as the `Angstrom
-Distribution <http://www.angstrom-distribution.org/>`__, and which is
-also being used as the build tool for Linux projects such as the `Yocto
-Project <http://www.yoctoproject.org>`__.
-
-Prior to BitBake, no other build tool adequately met the needs of an
-aspiring embedded Linux distribution. All of the build systems used by
-traditional desktop Linux distributions lacked important functionality,
-and none of the ad hoc Buildroot-based systems, prevalent in the
-embedded space, were scalable or maintainable.
-
-Some important original goals for BitBake were:
-
-  Handle cross-compilation.
-
-  Handle inter-package dependencies (build time on target architecture,
-   build time on native architecture, and runtime).
-
-  Support running any number of tasks within a given package,
-   including, but not limited to, fetching upstream sources, unpacking
-   them, patching them, configuring them, and so forth.
-
-  Be Linux distribution agnostic for both build and target systems.
-
-  Be architecture agnostic.
-
-  Support multiple build and target operating systems (e.g. Cygwin, the
-   BSDs, and so forth).
-
-  Be self-contained, rather than tightly integrated into the build
-   machine's root filesystem.
-
-  Handle conditional metadata on the target architecture, operating
-   system, distribution, and machine.
-
-  Be easy to use the tools to supply local metadata and packages
-   against which to operate.
-
-  Be easy to use BitBake to collaborate between multiple projects for
-   their builds.
-
-  Provide an inheritance mechanism to share common metadata between
-   many packages.
-
-Over time it became apparent that some further requirements were
-necessary:
-
-  Handle variants of a base recipe (e.g. native, sdk, and multilib).
-
-  Split metadata into layers and allow layers to enhance or override
-   other layers.
-
-  Allow representation of a given set of input variables to a task as a
-   checksum. Based on that checksum, allow acceleration of builds with
-   prebuilt components.
-
-BitBake satisfies all the original requirements and many more with
-extensions being made to the basic functionality to reflect the
-additional requirements. Flexibility and power have always been the
-priorities. BitBake is highly extensible and supports embedded Python
-code and execution of any arbitrary tasks.
-
-.. _Concepts:
-
-Concepts
-========
-
-BitBake is a program written in the Python language. At the highest
-level, BitBake interprets metadata, decides what tasks are required to
-run, and executes those tasks. Similar to GNU Make, BitBake controls how
-software is built. GNU Make achieves its control through "makefiles",
-while BitBake uses "recipes".
-
-BitBake extends the capabilities of a simple tool like GNU Make by
-allowing for the definition of much more complex tasks, such as
-assembling entire embedded Linux distributions.
-
-The remainder of this section introduces several concepts that should be
-understood in order to better leverage the power of BitBake.
-
-Recipes
-------
-
-BitBake Recipes, which are denoted by the file extension ``.bb``, are
-the most basic metadata files. These recipe files provide BitBake with
-the following:
-
-  Descriptive information about the package (author, homepage, license,
-   and so on)
-
-  The version of the recipe
-
-  Existing dependencies (both build and runtime dependencies)
-
-  Where the source code resides and how to fetch it
-
-  Whether the source code requires any patches, where to find them, and
-   how to apply them
-
-  How to configure and compile the source code
-
-  How to assemble the generated artifacts into one or more installable
-   packages
-
-  Where on the target machine to install the package or packages
-   created
-
-Within the context of BitBake, or any project utilizing BitBake as its
-build system, files with the ``.bb`` extension are referred to as
-recipes.
-
-.. note::
-
-   The term "package" is also commonly used to describe recipes.
-   However, since the same word is used to describe packaged output from
-   a project, it is best to maintain a single descriptive term -
-   "recipes". Put another way, a single "recipe" file is quite capable
-   of generating a number of related but separately installable
-   "packages". In fact, that ability is fairly common.
-
-Configuration Files
-------------------
-
-Configuration files, which are denoted by the ``.conf`` extension,
-define various configuration variables that govern the project's build
-process. These files fall into several areas that define machine
-configuration, distribution configuration, possible compiler tuning,
-general common configuration, and user configuration. The main
-configuration file is the sample ``bitbake.conf`` file, which is located
-within the BitBake source tree ``conf`` directory.
-
-Classes
-------
-
-Class files, which are denoted by the ``.bbclass`` extension, contain
-information that is useful to share between metadata files. The BitBake
-source tree currently comes with one class metadata file called
-``base.bbclass``. You can find this file in the ``classes`` directory.
-The ``base.bbclass`` class files is special since it is always included
-automatically for all recipes and classes. This class contains
-definitions for standard basic tasks such as fetching, unpacking,
-configuring (empty by default), compiling (runs any Makefile present),
-installing (empty by default) and packaging (empty by default). These
-tasks are often overridden or extended by other classes added during the
-project development process.
-
-Layers
------
-
-Layers allow you to isolate different types of customizations from each
-other. While you might find it tempting to keep everything in one layer
-when working on a single project, the more modular your metadata, the
-easier it is to cope with future changes.
-
-To illustrate how you can use layers to keep things modular, consider
-customizations you might make to support a specific target machine.
-These types of customizations typically reside in a special layer,
-rather than a general layer, called a Board Support Package (BSP) layer.
-Furthermore, the machine customizations should be isolated from recipes
-and metadata that support a new GUI environment, for example. This
-situation gives you a couple of layers: one for the machine
-configurations and one for the GUI environment. It is important to
-understand, however, that the BSP layer can still make machine-specific
-additions to recipes within the GUI environment layer without polluting
-the GUI layer itself with those machine-specific changes. You can
-accomplish this through a recipe that is a BitBake append
-(``.bbappend``) file.
-
-.. _append-bbappend-files:
-
-Append Files
------------
-
-Append files, which are files that have the ``.bbappend`` file
-extension, extend or override information in an existing recipe file.
-
-BitBake expects every append file to have a corresponding recipe file.
-Furthermore, the append file and corresponding recipe file must use the
-same root filename. The filenames can differ only in the file type
-suffix used (e.g. ``formfactor_0.0.bb`` and
-``formfactor_0.0.bbappend``).
-
-Information in append files extends or overrides the information in the
-underlying, similarly-named recipe files.
-
-When you name an append file, you can use the "``%``" wildcard character
-to allow for matching recipe names. For example, suppose you have an
-append file named as follows: ::
-
-  busybox_1.21.%.bbappend
-
-That append file
-would match any ``busybox_1.21.``\ x\ ``.bb`` version of the recipe. So,
-the append file would match the following recipe names: ::
-
-  busybox_1.21.1.bb
-  busybox_1.21.2.bb
-  busybox_1.21.3.bb
-
-.. note::
-
-   The use of the " % " character is limited in that it only works directly in
-   front of the .bbappend portion of the append file's name. You cannot use the
-   wildcard character in any other location of the name.
-
-If the ``busybox`` recipe was updated to ``busybox_1.3.0.bb``, the
-append name would not match. However, if you named the append file
-``busybox_1.%.bbappend``, then you would have a match.
-
-In the most general case, you could name the append file something as
-simple as ``busybox_%.bbappend`` to be entirely version independent.
-
-Obtaining BitBake
-=================
-
-You can obtain BitBake several different ways:
-
-  **Cloning BitBake:** Using Git to clone the BitBake source code
-   repository is the recommended method for obtaining BitBake. Cloning
-   the repository makes it easy to get bug fixes and have access to
-   stable branches and the master branch. Once you have cloned BitBake,
-   you should use the latest stable branch for development since the
-   master branch is for BitBake development and might contain less
-   stable changes.
-
-   You usually need a version of BitBake that matches the metadata you
-   are using. The metadata is generally backwards compatible but not
-   forward compatible.
-
-   Here is an example that clones the BitBake repository: ::
-
-     $ git clone git://git.openembedded.org/bitbake
-
-   This command clones the BitBake
-   Git repository into a directory called ``bitbake``. Alternatively,
-   you can designate a directory after the ``git clone`` command if you
-   want to call the new directory something other than ``bitbake``. Here
-   is an example that names the directory ``bbdev``: ::
-
-     $ git clone git://git.openembedded.org/bitbake bbdev
-
-  **Installation using your Distribution Package Management System:**
-   This method is not recommended because the BitBake version that is
-   provided by your distribution, in most cases, is several releases
-   behind a snapshot of the BitBake repository.
-
-  **Taking a snapshot of BitBake:** Downloading a snapshot of BitBake
-   from the source code repository gives you access to a known branch or
-   release of BitBake.
-
-      .. note::
-
-         Cloning the Git repository, as described earlier, is the preferred
-         method for getting BitBake. Cloning the repository makes it easier
-         to update as patches are added to the stable branches.
-
-   The following example downloads a snapshot of BitBake version 1.17.0: ::
-
-     $ wget http://git.openembedded.org/bitbake/snapshot/bitbake-1.17.0.tar.gz
-     $ tar zxpvf bitbake-1.17.0.tar.gz
-
-   After extraction of the tarball using
-   the tar utility, you have a directory entitled ``bitbake-1.17.0``.
-
-  **Using the BitBake that Comes With Your Build Checkout:** A final
-   possibility for getting a copy of BitBake is that it already comes
-   with your checkout of a larger BitBake-based build system, such as
-   Poky. Rather than manually checking out individual layers and gluing
-   them together yourself, you can check out an entire build system. The
-   checkout will already include a version of BitBake that has been
-   thoroughly tested for compatibility with the other components. For
-   information on how to check out a particular BitBake-based build
-   system, consult that build system's supporting documentation.

-
-The BitBake Command
-===================
-
-The ``bitbake`` command is the primary interface to the BitBake tool.
-This section presents the BitBake command syntax and provides several
-execution examples.
-
-Usage and syntax
----------------
-
-Following is the usage and syntax for BitBake: ::
-
-   $ bitbake -h
-   Usage: bitbake [options] [recipename/target recipe:do_task ...]
-
-       Executes the specified task (default is 'build') for a given set of target recipes (.bb files).
-       It is assumed there is a conf/bblayers.conf available in cwd or in BBPATH which
-       will provide the layer, BBFILES and other configuration information.
-
-   Options:
-     --version             show program's version number and exit
-     -h, --help            show this help message and exit
-     -b BUILDFILE, --buildfile=BUILDFILE
-                           Execute tasks from a specific .bb recipe directly.
-                           WARNING: Does not handle any dependencies from other
-                           recipes.
-     -k, --continue        Continue as much as possible after an error. While the
-                           target that failed and anything depending on it cannot
-                           be built, as much as possible will be built before
-                           stopping.
-     -f, --force           Force the specified targets/task to run (invalidating
-                           any existing stamp file).
-     -c CMD, --cmd=CMD     Specify the task to execute. The exact options
-                           available depend on the metadata. Some examples might
-                           be 'compile' or 'populate_sysroot' or 'listtasks' may
-                           give a list of the tasks available.
-     -C INVALIDATE_STAMP, --clear-stamp=INVALIDATE_STAMP
-                           Invalidate the stamp for the specified task such as
-                           'compile' and then run the default task for the
-                           specified target(s).
-     -r PREFILE, --read=PREFILE
-                           Read the specified file before bitbake.conf.
-     -R POSTFILE, --postread=POSTFILE
-                           Read the specified file after bitbake.conf.
-     -v, --verbose         Enable tracing of shell tasks (with 'set -x'). Also
-                           print bb.note(...) messages to stdout (in addition to
-                           writing them to ${T}/log.do_&lt;task&gt;).
-     -D, --debug           Increase the debug level. You can specify this more
-                           than once. -D sets the debug level to 1, where only
-                           bb.debug(1, ...) messages are printed to stdout; -DD
-                           sets the debug level to 2, where both bb.debug(1, ...)
-                           and bb.debug(2, ...) messages are printed; etc.
-                           Without -D, no debug messages are printed. Note that
-                           -D only affects output to stdout. All debug messages
-                           are written to ${T}/log.do_taskname, regardless of the
-                           debug level.
-     -q, --quiet           Output less log message data to the terminal. You can
-                           specify this more than once.
-     -n, --dry-run         Don't execute, just go through the motions.
-     -S SIGNATURE_HANDLER, --dump-signatures=SIGNATURE_HANDLER
-                           Dump out the signature construction information, with
-                           no task execution. The SIGNATURE_HANDLER parameter is
-                           passed to the handler. Two common values are none and
-                           printdiff but the handler may define more/less. none
-                           means only dump the signature, printdiff means compare
-                           the dumped signature with the cached one.
-     -p, --parse-only      Quit after parsing the BB recipes.
-     -s, --show-versions   Show current and preferred versions of all recipes.
-     -e, --environment     Show the global or per-recipe environment complete
-                           with information about where variables were
-                           set/changed.
-     -g, --graphviz        Save dependency tree information for the specified
-                           targets in the dot syntax.
-     -I EXTRA_ASSUME_PROVIDED, --ignore-deps=EXTRA_ASSUME_PROVIDED
-                           Assume these dependencies don't exist and are already
-                           provided (equivalent to ASSUME_PROVIDED). Useful to
-                           make dependency graphs more appealing
-     -l DEBUG_DOMAINS, --log-domains=DEBUG_DOMAINS
-                           Show debug logging for the specified logging domains
-     -P, --profile         Profile the command and save reports.
-     -u UI, --ui=UI        The user interface to use (knotty, ncurses or taskexp
-                           - default knotty).
-     --token=XMLRPCTOKEN   Specify the connection token to be used when
-                           connecting to a remote server.
-     --revisions-changed   Set the exit code depending on whether upstream
-                           floating revisions have changed or not.
-     --server-only         Run bitbake without a UI, only starting a server
-                           (cooker) process.
-     -B BIND, --bind=BIND  The name/address for the bitbake xmlrpc server to bind
-                           to.
-     -T SERVER_TIMEOUT, --idle-timeout=SERVER_TIMEOUT
-                           Set timeout to unload bitbake server due to
-                           inactivity, set to -1 means no unload, default:
-                           Environment variable BB_SERVER_TIMEOUT.
-     --no-setscene         Do not run any setscene tasks. sstate will be ignored
-                           and everything needed, built.
-     --setscene-only       Only run setscene tasks, don't run any real tasks.
-     --remote-server=REMOTE_SERVER
-                           Connect to the specified server.
-     -m, --kill-server     Terminate any running bitbake server.
-     --observe-only        Connect to a server as an observing-only client.
-     --status-only         Check the status of the remote bitbake server.
-     -w WRITEEVENTLOG, --write-log=WRITEEVENTLOG
-                           Writes the event log of the build to a bitbake event
-                           json file. Use '' (empty string) to assign the name
-                           automatically.
-     --runall=RUNALL       Run the specified task for any recipe in the taskgraph
-                           of the specified target (even if it wouldn't otherwise

-Examples
--------
-
-This section presents some examples showing how to use BitBake.
-
-.. _example-executing-a-task-against-a-single-recipe:
-
-Executing a Task Against a Single Recipe
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Executing tasks for a single recipe file is relatively simple. You
-specify the file in question, and BitBake parses it and executes the
-specified task. If you do not specify a task, BitBake executes the
-default task, which is "build". BitBake obeys inter-task dependencies
-when doing so.
-
-The following command runs the build task, which is the default task, on
-the ``foo_1.0.bb`` recipe file: ::
-
-  $ bitbake -b foo_1.0.bb
-
-The following command runs the clean task on the ``foo.bb`` recipe file: ::
-
-  $ bitbake -b foo.bb -c clean
-
-.. note::
-
-   The "-b" option explicitly does not handle recipe dependencies. Other
-   than for debugging purposes, it is instead recommended that you use
-   the syntax presented in the next section.
-
-Executing Tasks Against a Set of Recipe Files
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-There are a number of additional complexities introduced when one wants
-to manage multiple ``.bb`` files. Clearly there needs to be a way to
-tell BitBake what files are available and, of those, which you want to
-execute. There also needs to be a way for each recipe to express its
-dependencies, both for build-time and runtime. There must be a way for
-you to express recipe preferences when multiple recipes provide the same
-functionality, or when there are multiple versions of a recipe.
-
-The ``bitbake`` command, when not using "--buildfile" or "-b" only
-accepts a "PROVIDES". You cannot provide anything else. By default, a
-recipe file generally "PROVIDES" its "packagename" as shown in the
-following example: ::
-
-  $ bitbake foo
-
-This next example "PROVIDES" the
-package name and also uses the "-c" option to tell BitBake to just
-execute the ``do_clean`` task: ::
-
-  $ bitbake -c clean foo
-
-Executing a List of Task and Recipe Combinations
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The BitBake command line supports specifying different tasks for
-individual targets when you specify multiple targets. For example,
-suppose you had two targets (or recipes) ``myfirstrecipe`` and
-``mysecondrecipe`` and you needed BitBake to run ``taskA`` for the first
-recipe and ``taskB`` for the second recipe: ::
-
-  $ bitbake myfirstrecipe:do_taskA mysecondrecipe:do_taskB
-
-Generating Dependency Graphs
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-BitBake is able to generate dependency graphs using the ``dot`` syntax.
-You can convert these graphs into images using the ``dot`` tool from
-`Graphviz <http://www.graphviz.org>`__.
-
-When you generate a dependency graph, BitBake writes two files to the
-current working directory:
-
-  ``task-depends.dot``: Shows dependencies between tasks. These
-   dependencies match BitBake's internal task execution list.
-
-  ``pn-buildlist``: Shows a simple list of targets that are to be
-   built.
-
-To stop depending on common depends, use the "-I" depend option and
-BitBake omits them from the graph. Leaving this information out can
-produce more readable graphs. This way, you can remove from the graph
-``DEPENDS`` from inherited classes such as ``base.bbclass``.
-
-Here are two examples that create dependency graphs. The second example
-omits depends common in OpenEmbedded from the graph: ::
-
-  $ bitbake -g foo
-
-  $ bitbake -g -I virtual/kernel -I eglibc foo
-
-Executing a Multiple Configuration Build
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-BitBake is able to build multiple images or packages using a single
-command where the different targets require different configurations
-(multiple configuration builds). Each target, in this scenario, is
-referred to as a "multiconfig".
-
-To accomplish a multiple configuration build, you must define each
-target's configuration separately using a parallel configuration file in
-the build directory. The location for these multiconfig configuration
-files is specific. They must reside in the current build directory in a
-sub-directory of ``conf`` named ``multiconfig``. Following is an example
-for two separate targets:
-
-.. image:: figures/bb_multiconfig_files.png
-   :align: center
-
-The reason for this required file hierarchy is because the ``BBPATH``
-variable is not constructed until the layers are parsed. Consequently,
-using the configuration file as a pre-configuration file is not possible
-unless it is located in the current working directory.
-
-Minimally, each configuration file must define the machine and the
-temporary directory BitBake uses for the build. Suggested practice
-dictates that you do not overlap the temporary directories used during
-the builds.
-
-Aside from separate configuration files for each target, you must also
-enable BitBake to perform multiple configuration builds. Enabling is
-accomplished by setting the
-:term:`BBMULTICONFIG` variable in the
-``local.conf`` configuration file. As an example, suppose you had
-configuration files for ``target1`` and ``target2`` defined in the build
-directory. The following statement in the ``local.conf`` file both
-enables BitBake to perform multiple configuration builds and specifies
-the two extra multiconfigs: ::
-
-  BBMULTICONFIG = "target1 target2"
-
-Once the target configuration files are in place and BitBake has been
-enabled to perform multiple configuration builds, use the following
-command form to start the builds: ::
-
-  $ bitbake [mc:multiconfigname:]target [[[mc:multiconfigname:]target] ... ]
-
-Here is an example for two extra multiconfigs: ``target1`` and ``target2``: ::
-
-  $ bitbake mc::target mc:target1:target mc:target2:target
-
-.. _bb-enabling-multiple-configuration-build-dependencies:
-
-Enabling Multiple Configuration Build Dependencies
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Sometimes dependencies can exist between targets (multiconfigs) in a
-multiple configuration build. For example, suppose that in order to
-build an image for a particular architecture, the root filesystem of
-another build for a different architecture needs to exist. In other
-words, the image for the first multiconfig depends on the root
-filesystem of the second multiconfig. This dependency is essentially
-that the task in the recipe that builds one multiconfig is dependent on
-the completion of the task in the recipe that builds another
-multiconfig.
-
-To enable dependencies in a multiple configuration build, you must
-declare the dependencies in the recipe using the following statement
-form: ::
-
-  task_or_package[mcdepends] = "mc:from_multiconfig:to_multiconfig:recipe_name:task_on_which_to_depend"
-
-To better show how to use this statement, consider an example with two
-multiconfigs: ``target1`` and ``target2``: ::
-
-  image_task[mcdepends] = "mc:target1:target2:image2:rootfs_task"
-
-In this example, the
-``from_multiconfig`` is "target1" and the ``to_multiconfig`` is "target2". The
-task on which the image whose recipe contains image_task depends on the
-completion of the rootfs_task used to build out image2, which is
-associated with the "target2" multiconfig.
-
-Once you set up this dependency, you can build the "target1" multiconfig
-using a BitBake command as follows: ::
-
-  $ bitbake mc:target1:image1
-
-This command executes all the tasks needed to create ``image1`` for the "target1"
-multiconfig. Because of the dependency, BitBake also executes through
-the ``rootfs_task`` for the "target2" multiconfig build.
-
-Having a recipe depend on the root filesystem of another build might not
-seem that useful. Consider this change to the statement in the image1
-recipe: ::
-
-  image_task[mcdepends] = "mc:target1:target2:image2:image_task"
-
-In this case, BitBake must create ``image2`` for the "target2" build since
-the "target1" build depends on it.
-
-Because "target1" and "target2" are enabled for multiple configuration
-builds and have separate configuration files, BitBake places the
-artifacts for each build in the respective temporary build directories.

+        <title>Introduction</title>
+        <section>
+            <title>Overview</title>
+            <para>BitBake is, at its simplest, a tool for executing
+tasks and managing metadata.  As such, its similarities to GNU make and other
+build tools are readily apparent.  It was inspired by Portage, the package management system used by the Gentoo Linux distribution.  BitBake is the basis of the <ulink url="http://www.openembedded.org/">OpenEmbedded</ulink> project, which is being used to build and maintain a number of embedded Linux distributions, including OpenZaurus and Familiar.</para>
+        </section>
+        <section>
+            <title>Background and Goals</title>
+            <para>Prior to BitBake, no other build tool adequately met
+the needs of an aspiring embedded Linux distribution.  All of the
+buildsystems used by traditional desktop Linux distributions lacked
+important functionality, and none of the ad-hoc
+<emphasis>buildroot</emphasis> systems, prevalent in the
+embedded space, were scalable or maintainable.</para>
+
+      <para>Some important goals for BitBake were:
+            <itemizedlist>
+                <listitem><para>Handle crosscompilation.</para></listitem>
+                <listitem><para>Handle interpackage dependencies (build time on target architecture, build time on native architecture, and runtime).</para></listitem>
+                <listitem><para>Support running any number of tasks within a given package, including, but not limited to, fetching upstream sources, unpacking them, patching them, configuring them, et cetera.</para></listitem>
+                <listitem><para>Must be linux distribution agnostic (both build and target).</para></listitem>
+                <listitem><para>Must be architecture agnostic</para></listitem>
+                <listitem><para>Must support multiple build and target operating systems (including cygwin, the BSDs, etc).</para></listitem>
+                <listitem><para>Must be able to be self contained, rather than tightly integrated into the build machine's root filesystem.</para></listitem>
+                <listitem><para>There must be a way to handle conditional metadata (on target architecture, operating system, distribution, machine).</para></listitem>
+                <listitem><para>It must be easy for the person using the tools to supply their own local metadata and packages to operate against.</para></listitem>
+                <listitem><para>Must make it easy to collaborate
+between multiple projects using BitBake for their
+builds.</para></listitem>
+		<listitem><para>Should provide an inheritance mechanism to
+share common metadata between many packages.</para></listitem>
+                <listitem><para>Et cetera...</para></listitem>
+            </itemizedlist>
+        </para>
+        <para>BitBake satisfies all these and many more.  Flexibility and power have always been the priorities.  It is highly extensible, supporting embedded Python code and execution of any arbitrary tasks.</para>

+        <title>Metadata</title>
+        <section>
+            <title>Description</title>
+            <itemizedlist>
+                <para>BitBake metadata can be classified into 3 major areas:</para>
+                <listitem>
+                    <para>Configuration Files</para>
+                </listitem>
+                <listitem>
+                    <para>.bb Files</para>
+                </listitem>
+                <listitem>
+                    <para>Classes</para>
+                </listitem>
+            </itemizedlist>
+            <para>What follows are a large number of examples of BitBake metadata.  Any syntax which isn't supported in any of the aforementioned areas will be documented as such.</para>
+            <section>
+                <title>Basic variable setting</title>
+                <para><screen><varname>VARIABLE</varname> = "value"</screen></para>
+                <para>In this example, <varname>VARIABLE</varname> is <literal>value</literal>.</para>
+            </section>
+            <section>
+                <title>Variable expansion</title>
+                <para>BitBake supports variables referencing one another's contents using a syntax which is similar to shell scripting</para>
+                <para><screen><varname>A</varname> = "aval"
+<varname>B</varname> = "pre${A}post"</screen></para>
+                <para>This results in <varname>A</varname> containing <literal>aval</literal> and <varname>B</varname> containing <literal>preavalpost</literal>.</para>
+            </section>
+            <section>
+                <title>Setting a default value (?=)</title>
+                <para><screen><varname>A</varname> ?= "aval"</screen></para>
+                <para>If <varname>A</varname> is set before the above is called, it will retain it's previous value. If <varname>A</varname> is unset prior to the above call, <varname>A</varname> will be set to <literal>aval</literal>.  Note that this assignment is immediate, so if there are multiple ?= assignments to a single variable, the first of those will be used.</para>
+            </section>
+            <section>
+                <title>Setting a default value (??=)</title>
+                <para><screen><varname>A</varname> ??= "somevalue"</screen></para>
+                <para><screen><varname>A</varname> ??= "someothervalue"</screen></para>
+                <para>If <varname>A</varname> is set before the above, it will retain that value.  If <varname>A</varname> is unset prior to the above, <varname>A</varname> will be set to <literal>someothervalue</literal>.  This is a lazy version of ?=, in that the assignment does not occur until the end of the parsing process, so that the last, rather than the first, ??= assignment to a given variable will be used.</para>
+            </section>
+            <section>
+                <title>Immediate variable expansion (:=)</title>
+                <para>:= results in a variable's contents being expanded immediately, rather than when the variable is actually used.</para>
+                <para><screen><varname>T</varname> = "123"
+<varname>A</varname> := "${B} ${A} test ${T}"
+<varname>T</varname> = "456"
+<varname>B</varname> = "${T} bval"
+
+<varname>C</varname> = "cval"
+<varname>C</varname> := "${C}append"</screen></para>
+                <para>In that example, <varname>A</varname> would contain <literal> test 123</literal>, <varname>B</varname> would contain <literal>456 bval</literal>, and <varname>C</varname> would be <literal>cvalappend</literal>.</para>
+            </section>
+            <section>
+                <title>Appending (+=) and prepending (=+)</title>
+                <para><screen><varname>B</varname> = "bval"
+<varname>B</varname> += "additionaldata"
+<varname>C</varname> = "cval"
+<varname>C</varname> =+ "test"</screen></para>
+                <para>In this example, <varname>B</varname> is now <literal>bval additionaldata</literal> and <varname>C</varname> is <literal>test cval</literal>.</para>
+            </section>
+            <section>
+                <title>Appending (.=) and prepending (=.) without spaces</title>
+                    <para><screen><varname>B</varname> = "bval"
+<varname>B</varname> .= "additionaldata"
+<varname>C</varname> = "cval"
+<varname>C</varname> =. "test"</screen></para>
+                <para>In this example, <varname>B</varname> is now <literal>bvaladditionaldata</literal> and <varname>C</varname> is <literal>testcval</literal>. In contrast to the above Appending and Prepending operators no additional space
+will be introduced.</para>
+            </section>
+            <section>
+                <title>Conditional metadata set</title>
+                <para>OVERRIDES is a <quote>:</quote> separated variable containing each item you want to satisfy conditions.  So, if you have a variable which is conditional on <quote>arm</quote>, and <quote>arm</quote> is in OVERRIDES, then the <quote>arm</quote> specific version of the variable is used rather than the non-conditional version.  Example:</para>
+                <para><screen><varname>OVERRIDES</varname> = "architecture:os:machine"
+<varname>TEST</varname> = "defaultvalue"
+<varname>TEST_os</varname> = "osspecificvalue"
+<varname>TEST_condnotinoverrides</varname> = "othercondvalue"</screen></para>
+                <para>In this example, <varname>TEST</varname> would be <literal>osspecificvalue</literal>, due to the condition <quote>os</quote> being in <varname>OVERRIDES</varname>.</para>
+            </section>
+            <section>
+                <title>Conditional appending</title>
+                <para>BitBake also supports appending and prepending to variables based on whether something is in OVERRIDES.  Example:</para>
+                <para><screen><varname>DEPENDS</varname> = "glibc ncurses"
+<varname>OVERRIDES</varname> = "machine:local"
+<varname>DEPENDS_append_machine</varname> = " libmad"</screen></para>
+                <para>In this example, <varname>DEPENDS</varname> is set to <literal>glibc ncurses libmad</literal>.</para>
+            </section>
+            <section>
+                <title>Inclusion</title>
+                <para>Next, there is the <literal>include</literal> directive, which causes BitBake to parse in whatever file you specify, and insert it at that location, which is not unlike <command>make</command>.  However, if the path specified on the <literal>include</literal> line is a relative path, BitBake will locate the first one it can find within <envar>BBPATH</envar>.</para>
+            </section>
+            <section>
+                <title>Requiring Inclusion</title>
+                <para>In contrast to the <literal>include</literal> directive, <literal>require</literal> will
+raise an ParseError if the to be included file can not be found. Otherwise it will behave just like the <literal>
+include</literal> directive.</para>

+                <para><emphasis>NOTE:</emphasis> This is only supported in .bb and .bbclass files.</para>
+                <para>The <literal>inherit</literal> directive is a means of specifying what classes of functionality your .bb requires.  It is a rudimentary form of inheritance.  For example, you can easily abstract out the tasks involved in building a package that uses autoconf and automake, and put that into a bbclass for your packages to make use of.  A given bbclass is located by searching for classes/filename.oeclass in <envar>BBPATH</envar>, where filename is what you inherited.</para>

+                <para><emphasis>NOTE:</emphasis> This is only supported in .bb and .bbclass files.</para>
+                <para>In BitBake, each step that needs to be run for a given .bb is known as a task.  There is a command <literal>addtask</literal> to add new tasks (must be a defined python executable metadata and must start with <quote>do_</quote>) and describe intertask dependencies.</para>
+                <para><screen>python do_printdate () {
+    import time
+    print time.strftime('%Y%m%d', time.gmtime())
+}
+
+addtask printdate before do_build</screen></para>
+                <para>This defines the necessary python function and adds it as a task which is now a dependency of do_build (the default task).  If anyone executes the do_build task, that will result in do_printdate being run first.</para>
+            </section>

+                <title>Events</title>
+                <para><emphasis>NOTE:</emphasis> This is only supported in .bb and .bbclass files.</para>
+                <para>BitBake allows to install event handlers.  Events are triggered at certain points during operation, such as, the beginning of operation against a given .bb, the start of a given task, task failure, task success, et cetera.  The intent was to make it easy to do things like email notifications on build failure.</para>
+                <para><screen>addhandler myclass_eventhandler
+python myclass_eventhandler() {
+    from bb.event import getName
+    from bb import data

+    print("The file we run for is %s" % data.getVar('FILE', e.data, True))
+}
+</screen></para><para>
+This event handler gets called every time an event is triggered. A global variable <varname>e</varname> is defined. <varname>e</varname>.data contains an instance of bb.data. With the getName(<varname>e</varname>)
+method one can get the name of the triggered event.</para><para>The above event handler prints the name
+of the event and the content of the <varname>FILE</varname> variable.</para>
+            </section>
+            <section>
+                <title>Variants</title>
+                <para>Two Bitbake features exist to facilitate the creation of multiple buildable incarnations from a single recipe file.</para>
+                <para>The first is <varname>BBCLASSEXTEND</varname>.  This variable is a space separated list of classes to utilize to "extend" the recipe for each variant.  As an example, setting <screen>BBCLASSEXTEND = "native"</screen> results in a second incarnation of the current recipe being available.  This second incarantion will have the "native" class inherited.</para>
+                <para>The second feature is <varname>BBVERSIONS</varname>.  This variable allows a single recipe to be able to build multiple versions of a project from a single recipe file, and allows you to specify conditional metadata (using the <varname>OVERRIDES</varname> mechanism) for a single version, or an optionally named range of versions:</para>
+                <para><screen>BBVERSIONS = "1.0 2.0 git"
+SRC_URI_git = "git://someurl/somepath.git"</screen></para>
+                <para><screen>BBVERSIONS = "1.0.[0-6]:1.0.0+ \
+              1.0.[7-9]:1.0.7+"

+usage: bitbake [options] [package ...]
+
+Executes the specified task (default is 'build') for a given set of BitBake files.
+It expects that BBFILES is defined, which is a space separated list of files to
+be executed.  BBFILES does support wildcards.
+Default BBFILES are the .bb files in the current directory.
+
+options:
+  --version             show program's version number and exit
+  -h, --help            show this help message and exit
+  -b BUILDFILE, --buildfile=BUILDFILE
+                        execute the task against this .bb file, rather than a
+                        package from BBFILES.
+  -k, --continue        continue as much as possible after an error. While the
+                        target that failed, and those that depend on it,
+                        cannot be remade, the other dependencies of these
+                        targets can be processed all the same.
+  -f, --force           force run of specified cmd, regardless of stamp status
+  -i, --interactive     drop into the interactive mode also called the BitBake
+                        shell.
+  -c CMD, --cmd=CMD     Specify task to execute. Note that this only executes
+                        the specified task for the providee and the packages
+                        it depends on, i.e. 'compile' does not implicitly call
+                        stage for the dependencies (IOW: use only if you know
+                        what you are doing). Depending on the base.bbclass a
+                        listtasks task is defined and will show available
+                        tasks
+  -r FILE, --read=FILE  read the specified file before bitbake.conf
+  -v, --verbose         output more chit-chat to the terminal
+  -D, --debug           Increase the debug level. You can specify this more
+                        than once.
+  -n, --dry-run         don't execute, just go through the motions
+  -p, --parse-only      quit after parsing the BB files (developers only)
+  -d, --disable-psyco   disable using the psyco just-in-time compiler (not
+                        recommended)
+  -s, --show-versions   show current and preferred versions of all packages
+  -e, --environment     show the global or per-package environment (this is
+                        what used to be bbread)
+  -g, --graphviz        emit the dependency trees of the specified packages in
+                        the dot syntax
+  -I IGNORED_DOT_DEPS, --ignore-deps=IGNORED_DOT_DEPS
+                        Stop processing at the given list of dependencies when
+                        generating dependency graphs. This can help to make
+                        the graph more appealing
+  -l DEBUG_DOMAINS, --log-domains=DEBUG_DOMAINS
+                        Show debug logging for the specified logging domains
+  -P, --profile         profile the command and print a report

To stop depending on common depends one can use the <prompt>-I depend</prompt> to omit these from the graph. This can lead to more readable graphs.

The <varname>PN</varname> variable is, in general, by default, set to a component of the .bb filename.</para>

+                    <para>As you can see, here there are two different .bb's that provide the same functionality (virtual/package).  Clearly, there needs to be a way for the person running bitbake to control which of those providers gets used.  There is, indeed, such a way.</para>
+                    <para>The following would go into a .conf file, to select package1:
+    <screen>PREFERRED_PROVIDER_virtual/package = "package1"</screen>

+                    <title>Specifying version preference</title>
+                    <para>When there are multiple <quote>versions</quote> of a given package, bitbake defaults to selecting the most recent version, unless otherwise specified.  If the .bb in question has a <varname>DEFAULT_PREFERENCE</varname> set lower than the other .bb's (default is 0), then it will not be selected.  This allows the person or persons maintaining the repository of .bb files to specify their preferences for the default selected version.  In addition, the user can specify their preferences with regard to version.</para>
+                    <para>If the first .bb is named <filename>a_1.1.bb</filename>, then the <varname>PN</varname> variable will be set to <quote>a</quote>, and the <varname>PV</varname> variable will be set to 1.1.</para>
+                    <para>If we then have an <filename>a_1.2.bb</filename>, bitbake will choose 1.2 by default.  However, if we define the following variable in a .conf that bitbake parses, we can change that.
+    <screen>PREFERRED_VERSION_a = "1.1"</screen>

+                    <para>bbfile collections exist to allow the user to have multiple repositories of bbfiles that contain the same exact package.  For example, one could easily use them to make one's own local copy of an upstream repository, but with custom modifications that one does not want upstream.  Usage:</para>
+                    <screen>BBFILES = "/stuff/openembedded/*/*.bb /stuff/openembedded.modified/*/*.bb"
+BBFILE_COLLECTIONS = "upstream local"
+BBFILE_PATTERN_upstream = "^/stuff/openembedded/"
+BBFILE_PATTERN_local = "^/stuff/openembedded.modified/"
+BBFILE_PRIORITY_upstream = "5"
+BBFILE_PRIORITY_local = "10"</screen>

-BitBake code parser
-
-Parses actual code (i.e. python and shell) for functions and in-line
-expressions. Used mainly to determine dependencies on other functions
-and variables within the BitBake metadata. Also provides a cache for
-this information in order to speed up processing.
-
-(Not to be confused with the code that parses the metadata itself,
-see lib/bb/parse/ for that).
-
-NOTE: if you change how the parsers gather information you will almost
-certainly need to increment CodeParserCache.CACHE_VERSION below so that
-any existing codeparser cache gets invalidated. Additionally you'll need
-to increment __cache_version__ in cache.py in order to ensure that old
-recipe caches don't trigger "Taskhash mismatch" errors.

+Python Deamonizing helper

-Originally based on code Copyright (C) 2005 Chad J. Schroeder but now heavily modified
-to allow a function to be daemonized and return for bitbake use by Richard Purdie
+Configurable daemon behaviors:
+
+    1.) The current working directory set to the "/" directory.
+    2.) The current file creation mode mask set to 0.
+    3.) Close all open files (1024). 
+    4.) Redirect standard I/O streams to "/dev/null".
+
+A failed call to fork() now raises an exception.

+        #
+        #    1) When the process that dies is the session leader of a session that
+        #        is attached to a terminal device, SIGHUP is sent to all processes
+        #        in the foreground process group of that terminal device.
