+Poky platform builder is a combined cross build system and development 
+environment. It features support for building X11/Matchbox/GTK based 
+filesystem images for various embedded devices and boards. It also 
+supports cross-architecture application development using QEMU emulation
+and a standalone toolchain and SDK with IDE integration.
 
+Poky has an extensive handbook, the source of which is contained in
+the handbook directory. For compiled HTML or pdf versions of this, 
+see the Poky website http://pokylinux.org.
 
-Required Packages
-===
-
-Running Poky on Debian based distributions requires the following
-extra packages be installed;
-
-build-essential
-diffstat
-texinfo
-texi2html
-cvs
-subversion
-gawk
-bochsbios (to run qemux86 images)
-
-You also need to install the qemu from http://debian.o-hand.com/. A
-poky-depends deb is also available from this source which will install 
-all the dependencies mentioned above for you.
-
-Alternatively poky can build qemu itself, but for this you need the
-following packages installed;
-
-gcc-3.4
-libsdl1.2-dev
-zlib1g-dev
-
-You will also need to comment out ASSUME_PROVIDED += "qemu-native"' in  
-build/conf/local.conf.
-
-Building under other distro's such as Fedora is known to work. Use the above
-package names as a guide for dependencies.
-
-Building An Image
-===
-
-Simply run;
-
-% source poky-init-build-env
-% bitbake oh-image-pda
-
-This will result in an ext2 image and kernel for qemu arm (see scripts dir).
-
-To build for other machine types see MACHINE in build/conf/local.conf

+Poky Boot CD (bootcdx86)
+========================
+
+The Poky boot CD iso images are designed as a demonstration of the Poky 
+environment and to show the versatile image formats Poky can generate. It will
+run on Pentium2 or greater PC style computers. The iso image can be 
+burnt to CD and then booted from.
+
+
+                          Hardware Reference Boards
+                          =========================
+
+Compulab CM-X270 (cm-x270)
+==========================
+
+The bootloader on this board doesn't support writing jffs2 images directly to 
+NAND and normally uses a proprietary kernel flash driver. To allow the use of
+jffs2 images, a two stage updating procedure is needed. Firstly, an initramfs
+is booted which contains mtd utilities and this is then used to write the main
+filesystem. 
+
+It is assumed the board is connected to a network where a TFTP server is 
+available and that a serial terminal is available to communicate with the 
+bootloader (38400, 8N1). If a DHCP server is available the device will use it
+to obtain an IP address. If not, run:
+
+  ARMmon > setip dhcp off
+  ARMmon > setip ip 192.168.1.203
+  ARMmon > setip mask 255.255.255.0
+
+To reflash the kernel:
+
+  ARMmon > download kernel tftp zimage 192.168.1.202
+  ARMmon > flash kernel
+
+where zimage is the name of the kernel on the TFTP server and its IP address is 
+192.168.1.202. The names of the files must be all lowercase.
+
+To reflash the initrd/initramfs:
+
+  ARMmon > download ramdisk tftp diskimage 192.168.1.202
+  ARMmon > flash ramdisk
+
+where diskimage is the name of the initramfs image (a cpio.gz file).
+
+To boot the initramfs:
+
+  ARMmon > ramdisk on
+  ARMmon > bootos "console=ttyS0,38400 rdinit=/sbin/init"
+
+To reflash the main image login to the system as user "root", then run:
+
+  # ifconfig eth0 192.168.1.203
+  # tftp -g -r mainimage 192.168.1.202
+  # flash_eraseall /dev/mtd1
+  # nandwrite /dev/mtd1 mainimage
+
+which configures the network interface with the IP address 192.168.1.203,
+downloads the "mainimage" file from the TFTP server at 192.168.1.202, erases
+the flash and then writes the new image to the flash.
+
+The main image can then be booted with:
+
+  ARMmon > bootos "console=ttyS0,38400 root=/dev/mtdblock1 rootfstype=jffs2"
+
+Note that the initramfs image is built by poky in a slightly different mode to
+normal since it uses uclibc. To generate this use a command like:
+
+IMAGE_FSTYPES=cpio.gz MACHINE=cm-x270 POKYLIBC=uclibc bitbake poky-image-minimal-mtdutils
+
+
+Compulab EM-X270 (em-x270)
+==========================
+
+Fetch the "Linux - kernel and run-time image (Angstrom)" ZIP file from the
+Compulab website. Inside the images directory of this ZIP file is another ZIP
+file called 'LiveDisk.zip'. Extract this over a cleanly formatted vfat USB flash
+drive. Replace the 'em_x270.img' file with the 'updater-em-x270.ext2' file.
+
+Insert this USB disk into the supplied adapter and connect this to the
+board. Whilst holding down the the suspend button press the reset button. The
+board will now boot off the USB key and into a version of Angstrom. On the
+desktop is an icon labelled "Updater". Run this program to launch the updater
+that will flash the Poky kernel and rootfs to the board.
+
+
+FreeScale iMX31ADS (mx31ads)
+===========================
+
+The correct serial port is the top-most female connector to the right of the
+ethernet socket.
+
+For uploading data to RedBoot we are going to use tftp. In this example we
+assume that the tftpserver is on 192.168.9.1 and the board is on192.168.9.2. 
+
+To set the IP address, run:
+
+  ip_address -l 192.168.9.2/24 -h 192.168.9.1
+
+To download a kernel called "zimage" from the TFTP server, run:
+
+  load -r -b 0x100000 zimage
+
+To write the kernel to flash run:
+
+  fis create kernel
+
+To download a rootfs jffs2 image "rootfs" from the TFTP server, run:
+
+  load -r -b 0x100000 rootfs
+
+To write the root filesystem  to flash run:
+
+  fis create root
+
+To load and boot a kernel and rootfs from flash:
+
+  fis load kernel
+  exec -b 0x100000 -l 0x200000 -c "noinitrd console=ttymxc0,115200 root=/dev/mtdblock2 rootfstype=jffs2 init=linuxrc ip=none"
+
+To load and boot a kernel from a TFTP server with the rootfs over NFS:
+
+  load -r -b 0x100000 zimage
+  exec -b 0x100000 -l 0x200000 -c "noinitrd console=ttymxc0,115200 root=/dev/nfs nfsroot=192.168.9.1:/mnt/nfsmx31 rw ip=192.168.9.2::192.168.9.1:255.255.255.0"
+
+The instructions above are for using the (default) NOR flash on the board,
+there is also 128M of NAND flash. It is possible to install Poky to the NAND 
+flash which gives more space for the rootfs and instructions for using this are
+given below. To switch to the NAND flash:
+
+  factive NAND
+
+This will then restart RedBoot using the NAND rather than the NOR. If you
+have not used the NAND before then it is unlikely that there will be a
+partition table yet. You can get the list of partitions with 'fis list'.
+
+If this shows no partitions then you can create them with:
+
+  fis init
+
+The output of 'fis list' should now show:
+
+Name              FLASH addr  Mem addr    Length      Entry point
+RedBoot           0xE0000000  0xE0000000  0x00040000  0x00000000
+FIS directory     0xE7FF4000  0xE7FF4000  0x00003000  0x00000000
+RedBoot config    0xE7FF7000  0xE7FF7000  0x00001000  0x00000000
+
+Partitions for the kernel and rootfs need to be created:
+
+fis create -l 0x1A0000 -e 0x00100000 kernel
+fis create -l 0x5000000 -e 0x00100000 root
+
+You may now use the instructions above for flashing. However it is important
+to note that the erase block size for the NAND is different to the NOR so the
+JFFS erase size will need to be changed to 0x4000. Stardard images are built
+for NOR and you will need to build custom images for NAND.
+
+You will also need to update the kernel command line to use the correct root
+filesystem. This should be '/dev/mtdblock7' if you adhere to the partitioning
+scheme shown above. If this fails then you can doublecheck against the output
+from the kernel when it evaluates the available mtd partitions.
+
+
+Marvell PXA3xx Zylonite (zylonite)
+==================================
+
+These instructions assume the Zylonite is connected to a machine running a TFTP 
+server at address 192.168.123.5 and that a serial link (38400 8N1) is available 
+to access the blob bootloader. The kernel is on the TFTP server as 
+"zylonite-kernel" and the root filesystem jffs2 file is "zylonite-rootfs" and 
+the images are to be saved in NAND flash.
+
+The following commands setup blob:
+
+  blob> setip client 192.168.123.4
+  blob> setip server 192.168.123.5
+
+To flash the kernel:
+
+  blob> tftp zylonite-kernel
+  blob> nandwrite -j 0x80800000 0x60000 0x200000
+
+To flash the rootfs:
+
+  blob> tftp zylonite-rootfs
+  blob> nanderase -j 0x260000 0x5000000
+  blob> nandwrite -j 0x80800000 0x260000 <length>
+
+(where <length> is the rootfs size which will be printed by the tftp step)
+
+To boot the board:
+
+  blob> nkernel
+  blob> boot
+
+
+Logic iMX31 Lite Kit (mx31litekit)
+===============================
+
+The easiest method to boot this board is to take an MMC/SD card and format 
+the first partition as ext2, then extract the poky image onto this as root. 
+Assuming the board is network connected, a TFTP server is available at 
+192.168.1.33 and a serial terminal is available (115200 8N1), the following 
+commands will boot a kernel called "mx31kern" from the TFTP server:
+
+  losh> ifconfig sm0 192.168.1.203 255.255.255.0 192.168.1.33
+  losh> load raw 0x80100000 0x200000 /tftp/192.168.1.33:mx31kern
+  losh> exec 0x80100000 - 
+
+
+Phytec phyCORE-iMX31 (mx31phy)
+==============================
+
+Support for this board is currently being developed. Experimental jffs2 
+images and a suitable kernel are available and are known to work with the
+board.
+
+
+                             Consumer Devices
+                             ================
+
+FIC Neo1973 GTA01 smartphone (fic-gta01)
+========================================
+
+To install Poky on a GTA01 smartphone you will need "dfu-util" tool
+which you can build with "bitbake dfu-util-native" command.
+
+Flashing requires these steps:
+
+  1. Power down the device.
+  2. Connect the device to the host machine via USB.
+  3. Hold AUX key and press Power key. There should be a bootmenu
+     on screen.
+  4. Run "dfu-util -l" to check if the phone is visible on the USB bus. 
+     The output should look like this:
+
+     dfu-util - (C) 2007 by OpenMoko Inc.
+     This program is Free Software and has ABSOLUTELY NO WARRANTY
+
+     Found Runtime: [0x1457:0x5119] devnum=19, cfg=0, intf=2, alt=0, name="USB Device Firmware Upgrade"
+
+  5. Flash the kernel with "dfu-util -a kernel -D uImage-2.6.21.6-moko11-r2-fic-gta01.bin"
+  6. Flash rootfs with "dfu-util -a rootfs -D <image>", where <image> is the
+     jffs2 image file to use as the root filesystem 
+     (e.g. ./tmp/deploy/images/poky-image-sato-fic-gta01.jffs2) 
+
+
+HTC Universal (htcuniversal)
+============================
+
+Note: HTC Universal support is highly experimental.
+
+On the HTC Universal, entirely replacing the Windows installation is not 
+supported, instead Poky is booted from an MMC/SD card from Windows. Once Poky
+has booted, Windows is no longer in memory or active but when power is removed,
+the user will be returned to windows and will need to return to Linux from 
+there.
+
+Once an MMC/SD card is available it is suggested its split into two partitions,
+one for a program called HaRET which lets you boot Linux from within Windows
+and the second for the rootfs. The HaRET partition should be the first partition
+on the card and be vfat formatted. It doesn't need to be large, just enough for
+HaRET and a kernel (say 5MB max). The rootfs should be ext2 and is usually the 
+second partition. The first partition should be vfat so Windows recognises it 
+as if it doesn't, it has been known to reformat cards.
+
+On the first partition you need three files:
+
+  * a HaRET binary (version 0.5.1 works well and a working version 
+    should be part of the last Poky release)
+  * a kernel renamed to "zImage"
+  * a default.txt which contains:
+
+set kernel "zImage"
+set mtype "855"
+set cmdline "root=/dev/mmcblk0p2 rw console=ttyS0,115200n8 console=tty0 rootdelay=5 fbcon=rotate:1"
+boot2
+
+On the second parition the root file system is extracted as root. A different
+partition layout or other kernel options can be changed in the default.txt file.
+
+When inserted into the device, Windows should see the card and let you browse
+its contents using File Explorer. Running the HaRET binary will present a dialog
+box (maybe after messages warning about running unsigned binaries) where you 
+select OK and you should then see Poky boot. Kernel messages can be seen by 
+adding psplash=false to the kernel commandline.
+
+
+Nokia 770/N800/N810 Internet Tablets (nokia770 and nokia800)
+============================================================
+
+Note: Nokia tablet support is highly experimental.
+
+The Nokia internet tablet devices are OMAP based tablet formfactor devices 
+with large screens (800x480), wifi and touchscreen.
+
+To flash images to these devices you need the "flasher" utility which can be 
+downloaded from the http://tablets-dev.nokia.com/d3.php?f=flasher-3.0. This 
+utility needs to be run as root and the usb filesystem needs to be mounted 
+although most distributions will have done this for you. Once you have this 
+follow these steps:
+
+  1. Power down the device.
+  2. Connect the device to the host machine via USB 
+     (connecting power to the device doesn't hurt either).
+  3. Run "flasher -i"
+  4. Power on the device.
+  5. The program should give an indication it's found 
+     a tablet device. If not, recheck the cables, make sure you're 
+     root and usbfs/usbdevfs is mounted.
+  6. Run "flasher -r <image> -k <kernel> -f", where <image> is the
+     jffs2 image file to use as the root filesystem 
+     (e.g. ./tmp/deploy/images/poky-image-sato-nokia800.jffs2) 
+     and <kernel> is the kernel to use 
+     (e.g. ./tmp/deploy/images/zImage-nokia800.bin).
+  7. Run "flasher -R" to reboot the device.
+  8. The device should boot into Poky.
+
+The nokia800 images and kernel will run on both the N800 and N810.
+
+
+Sharp Zaurus SL-C7x0 series (c7x0)
+==================================
+
+The Sharp Zaurus c7x0 series (SL-C700, SL-C750, SL-C760, SL-C860, SL-7500)
+are PXA25x based handheld PDAs with VGA screens. To install Poky images on
+these devices follow these steps:
+
+  1. Obtain an SD/MMC or CF card with a vfat or ext2 filesystem.
+  2. Copy a jffs2 image file (e.g. poky-image-sato-c7x0.jffs2) onto the
+     card as "initrd.bin":
+
+     $ cp ./tmp/deploy/images/poky-image-sato-c7x0.jffs2 /path/to/my-cf-card/initrd.bin
+
+  3. Copy an Linux kernel file (zImage-c7x0.bin) onto the card as 
+     "zImage.bin":
+
+     $ cp ./tmp/deploy/images/zImage-c7x0.bin /path/to/my-cf-card/zImage.bin
+
+  4. Copy an updater script (updater.sh.c7x0) onto the card
+     as "updater.sh":
+
+     $ cp ./tmp/deploy/images/updater.sh.c7x0 /path/to/my-cf-card/updater.sh
+
+  5. Power down the Zaurus.
+  6. Hold "OK" key and power on the device. An update menu should appear 
+     (in Japanese).
+  7. Choose "Update" (item 4).
+  8. The next screen will ask for the source, choose the appropriate 
+     card (CF or SD).
+  9. Make sure AC power is connected.
+  10. The next screen asks for confirmation, choose "Yes" (the left button).
+  11. The update process will start, flash the files on the card onto 
+      the device and the device will then reboot into Poky.
+
+
+Sharp Zaurus SL-C1000 (akita)
+=============================
+
+The Sharp Zaurus SL-C1000 is a PXA270 based device otherwise similar to the 
+c7x0. To install Poky images on this device follow the instructions for 
+the c7x0 but replace "c7x0" with "akita" where appropriate.
+
+
+Sharp Zaurus SL-C3x00 series (spitz)
+====================================
+
+The Sharp Zaurus SL-C3x00 devices are PXA270 based devices similar
+to akita but with an internal microdrive. The installation procedure 
+assumes a standard microdrive based device where the root (first) 
+partition has been enlarged to fit the image (at least 100MB, 
+400MB for the SDK).
+
+The procedure is the same as for the c7x0 and akita models with the 
+following differences:
+
+ 1. Instead of a jffs2 image you need to copy a compressed tarball of the 
+    root fileystem (e.g. poky-image-sato-spitz.tar.gz) onto the
+    card as "hdimage1.tgz":
+
+    $ cp ./tmp/deploy/images/poky-image-sato-spitz.tar.gz /path/to/my-cf-card/hdimage1.tgz
+
+ 2. You additionally need to copy a special tar utility  (gnu-tar) onto 
+    the card as "gnu-tar":
+
+    $ cp ./tmp/deploy/images/gnu-tar /path/to/my-cf-card/gnu-tar
+
+
+

+	- Add support for "-e target" (#3432)
+	- Fix shell showdata command (#3259)
+	- Fix shell data updating problems (#1880)
+	- Properly raise errors for invalid source URI protocols
+	- Change the wget fetcher failure handling to avoid lockfile problems
+	- Add git branch support
+	- Add support for branches in git fetcher (Otavio Salvador, Michael Lauer)
+	- Make taskdata and runqueue errors more user friendly
+	- Add norecurse and fullpath options to cvs fetcher
+
+Changes in Bitbake 1.8.8:
+	- Rewrite svn fetcher to make adding extra operations easier 
+	  as part of future SRCDATE="now" fixes
+	  (requires new FETCHCMD_svn definition in bitbake.conf)
+	- Change SVNDIR layout to be more unique (fixes #2644 and #2624)
+	- Import persistent data store from trunk
+	- Sync fetcher code with that in trunk, adding SRCREV support for svn
+	- Add ConfigParsed Event after configuration parsing is complete
+	- data.emit_var() - only call getVar if we need the variable
+	- Stop generating the A variable (seems to be legacy code)
+	- Make sure intertask depends get processed correcting in recursive depends
+	- Add pn-PN to overrides when evaluating PREFERRED_VERSION
+	- Improve the progress indicator by skipping tasks that have 
+	  already run before starting the build rather than during it
+	- Add profiling option (-P)
+	- Add BB_SRCREV_POLICY variable (clear or cache) to control SRCREV cache
+	- Add SRCREV_FORMAT support
+	- Fix local fetcher's localpath return values
+	- Apply OVERRIDES before performing immediate expansions
+	- Allow the -b -e option combination to take regular expressions
+	- Add plain message function to bb.msg
+	- Sort the list of providers before processing so dependency problems are 
+	  reproducible rather than effectively random
+	- Add locking for fetchers so only one tries to fetch a given file at a given time
+	- Fix int(0)/None confusion in runqueue.py which causes random gaps in dependency chains
+	- Fix handling of variables with expansion in the name using _append/_prepend
+	  e.g. RRECOMMENDS_${PN}_append_xyz = "abc"
+	- Expand data in addtasks
+ 	- Print the list of missing DEPENDS,RDEPENDS for the "No buildable providers available for required...."
+ 	  error message.
+	- Rework add_task to be more efficient (6% speedup, 7% number of function calls reduction)
+	- Sort digraph output to make builds more reproducible
+	- Split expandKeys into two for loops to benefit from the expand_cache (12% speedup)
+	- runqueue.py: Fix idepends handling to avoid dependency errors
+	- Clear the terminal TOSTOP flag if set (and warn the user)
+	- Fix regression from r653 and make SRCDATE/CVSDATE work for packages again
+
+Changes in Bitbake 1.8.6:
+	- Correctly redirect stdin when forking
+	- If parsing errors are found, exit, too many users miss the errors
+	- Remove supriours PREFERRED_PROVIDER warnings
+
+Changes in Bitbake 1.8.4:
+	- Make sure __inherit_cache is updated before calling include() (from Michael Krelin)
+	- Fix bug when target was in ASSUME_PROVIDED (#2236)
+	- Raise ParseError for filenames with multiple underscores instead of infinitely looping (#2062)
+	- Fix invalid regexp in BBMASK error handling (missing import) (#1124)
+	- Don't run build sanity checks on incomplete builds
+	- Promote certain warnings from debug to note 2 level
+	- Update manual
+
+Changes in Bitbake 1.8.2:

+	- Allow operations other than assignment on flag variables
+	- Fix cache errors when generation dotGraphs
+
+Changes in Bitbake 1.8.0:
+	- Release 1.7.x as a stable series
+
+Changes in BitBake 1.7.x:
+	- Major updates of the dependency handling and execution
+	  of tasks. Code from bin/bitbake replaced with runqueue.py
+	  and taskdata.py
+	- New task execution code supports multithreading with a simplistic
+	  threading algorithm controlled by BB_NUMBER_THREADS
+	- Change of the SVN Fetcher to keep the checkout around
+	  courtsey of Paul Sokolovsky (#1367)
+	- PATH fix to bbimage (#1108)
+	- Allow debug domains to be specified on the commandline (-l)
+	- Allow 'interactive' tasks
+	- Logging message improvements
+	- Drop now uneeded BUILD_ALL_DEPS variable
+	- Add support for wildcards to -b option
+	- Major overhaul of the fetchers making a large amount of code common
+	  including mirroring code
+	- Fetchers now touch md5 stamps upon access (to show activity)
+	- Fix -f force option when used without -b (long standing bug)
+	- Add expand_cache to data_cache.py, caching expanded data (speedup)
+	- Allow version field in DEPENDS (ignored for now)
+	- Add abort flag support to the shell
+	- Make inherit fail if the class doesn't exist (#1478)
+	- Fix data.emit_env() to expand keynames as well as values
+	- Add ssh fetcher
+	- Add perforce fetcher
+	- Make PREFERRED_PROVIDER_foobar defaults to foobar if available
+	- Share the parser's mtime_cache, reducing the number of stat syscalls
+	- Compile all anonfuncs at once! 
+	  *** Anonfuncs must now use common spacing format ***
+	- Memorise the list of handlers in __BBHANDLERS and tasks in __BBTASKS
+	  This removes 2 million function calls resulting in a 5-10% speedup
+	- Add manpage
+	- Update generateDotGraph to use taskData/runQueue improving accuracy
+	  and also adding a task dependency graph
+	- Fix/standardise on GPLv2 licence

-To ease portability (lemon, flex, etc) we keep the
-result of flex and lemon in the source code. We agree
-to not manually change the scanner and parser.
-
-
-
-How we create the files:
-   flex -t bitbakescanner.l > bitbakescanner.cc
-   lemon bitbakeparser.y
-   mv bitbakeparser.c bitbakeparser.cc
-
-Now manually create two files

-   DESCRIPTION
-   -----------
-
-   lemon parser specification file for a BitBake input file parser.
-
-   Most of the interesting shenanigans are done in the lexer.  The
-   BitBake grammar is not regular.  In order to emit tokens that
-   the parser can properly interpret in LALR fashion, the lexer
-   manages the interpretation state.  This is why there are ISYMBOLs,
-   SYMBOLS, and TSYMBOLS.
-
-   This parser was developed by reading the limited available
-   documentation for BitBake and by analyzing the available BB files.
-   There is no assertion of correctness to be made about this parser.

-   DESCRIPTION
-   -----------
-
-   flex lexer specification for a BitBake input file parser.
-
-   Unfortunately, flex doesn't welcome comments within the rule sets.
-   I say unfortunately because this lexer is unreasonably complex and
-   comments would make the code much easier to comprehend.
-
-   The BitBake grammar is not regular.  In order to interpret all
-   of the available input files, the lexer maintains much state as it
-   parses.  There are places where this lexer will emit tokens that
-   are invalid.  The parser will tend to catch these. 
-
-   The lexer requires C++ at the moment.  The only reason for this has
-   to do with a very small amount of managed state.  Producing a C
-   lexer should be a reasonably easy task as long as the %reentrant
-   option is used.
-
-
-   NOTES
-   -----
-
-   o RVALUES.  There are three kinds of RVALUES.  There are unquoted
-     values, double quote enclosed strings, and single quote 
-     strings.  Quoted strings may contain unescaped quotes (of either
-     type), *and* any type may span more than one line by using a
-     continuation '\' at the end of the line.  This requires us to
-     recognize all types of values with a single expression.
-     Moreover, the only reason to quote a value is to include
-     trailing or leading whitespace.  Whitespace within a value is
-     preserved, ugh.
-
-   o CLASSES.  C_ patterns define classes.  Classes ought not include
-     a repitition operator, instead letting the reference to the class
-     define the repitition count.
-
-     C_SS - symbol start
-     C_SB - symbol body
-     C_SP - whitespace

+            The meta-toolchain and meta-toolchain-sdk targets (<link linkend='ref-images'>see
+            the images section</link>) build tarballs which contain toolchains and 
+            libraries suitable for application development outside Poky. These unpack into the 
+            <filename class="directory">/usr/local/poky</filename> directory and contain
+            a setup script, e.g. 
+            <filename>/usr/local/poky/eabi-glibc/arm/environment-setup</filename> which
+            can be sourced to initialise a suitable environment. After sourcing this, the 
+            compiler, QEMU scripts, QEMU binary, a special version of pkgconfig and other 
+            useful utilities are added to the PATH. Variables to assist pkgconfig and 
+            autotools are also set so that, for example, configure can find pre-generated test 
+            results for tests which need target hardware to run.
+        </para>
+
+        <para>
+            Using the toolchain with autotool enabled packages is straightforward, just pass the 
+            appropriate host option to configure e.g. "./configure --host=arm-poky-linux-gnueabi".
+            For other projects it is usually a case of ensuring the cross tools are used e.g.
+            CC=arm-poky-linux-gnueabi-gcc and LD=arm-poky-linux-gnueabi-ld.

+            (<command>export CC="distcc"</command> can be set in the enviroment).
+            Alterntatively, if a suitable SDK/toolchain is present in

+            configure will be able to find the Poky site files etc. Within this

+

+        <ulink url="http://sourceware.org/gdb/">GDB</ulink> (The GNU Project Debugger)
+        allows you to examine running programs to understand and fix problems and
+        also to perform postmortem style analsys of program crashes. It is available
+        as a package within poky and installed by default in sdk images. It works best
+        when -dbg packages for the application being debugged are installed as the 
+        extra symbols give more meaningful output from GDB. 
+    </para>
+
+    <para>
+        Sometimes, due to memory or disk space constraints, it is not possible
+        to use GDB directly on the remote target to debug applications. This is 
+        due to the fact that
+        GDB needs to load the debugging information and the binaries of the
+        process being debugged. GDB then needs to perform many
+        computations to locate information such as function names, variable
+        names and values, stack traces, etc. even before starting the debugging
+        process. This places load on the target system and can alter the
+        characteristics of the program being debugged.
+    </para>
+    <para>
+        This is where GDBSERVER comes into play as it runs on the remote target
+        and does not load any debugging information from the debugged process.
+        Instead, the debugging information processing is done by a GDB instance
+        running on a distant computer - the host GDB. The host GDB then sends 
+        control commands to GDBSERVER to make it stop or start the debugged 
+        program, as well as read or write some memory regions of that debugged
+        program. All the debugging information loading and processing as well
+        as the heavy debugging duty is done by the host GDB, giving the 
+        GDBSERVER running on the target a chance to remain small and fast.
+    </para>
+    <para>
+        As the host GDB is responsible for loading the debugging information and 
+        doing the necessary processing to make actual debugging happen, the 
+        user has to make sure it can access the unstripped binaries complete
+        with their debugging information and compiled with no optimisations. The
+        host GDB must also have local access to all the libraries used by the 
+        debugged program. On the remote target the binaries can remain stripped
+        as GDBSERVER does not need any debugging information there. However they 
+        must also be compiled without optimisation matching the host's binaries.
+    </para>
+
+    <para>
+        The binary being debugged on the remote target machine is hence referred

+    <title>Profiling with OProfile</title>
+
+    <para>
+        <ulink url="http://oprofile.sourceforge.net/">OProfile</ulink> is a 
+        statistical profiler well suited to finding performance 
+        bottlenecks in both userspace software and the kernel. It provides 
+        answers to questions like "Which functions does my application spend 
+        the most time in when doing X?". Poky is well integrated with OProfile
+        to make profiling applications on target hardware straightforward.
+    </para>
+
+    <para>
+        To use OProfile you need an image with OProfile installed. The easiest 
+        way to do this is with "tools-profile" in <glossterm><link 
+        linkend='var-IMAGE_FEATURES'>IMAGE_FEATURES</link></glossterm>. You also
+        need debugging symbols to be available on the system where the analysis 
+        will take place. This can be achieved with "dbg-pkgs" in <glossterm><link 
+        linkend='var-IMAGE_FEATURES'>IMAGE_FEATURES</link></glossterm> or by
+        installing the appropriate -dbg packages. For 
+        successful call graph analysis the binaries must preserve the frame 
+        pointer register and hence should be compiled with the 
+        "-fno-omit-framepointer" flag. In Poky this can be achieved with 
+        <glossterm><link linkend='var-SELECTED_OPTIMIZATION'>SELECTED_OPTIMIZATION
+        </link></glossterm> = "-fexpensive-optimizations -fno-omit-framepointer 
+        -frename-registers -O2" or by setting <glossterm><link 
+        linkend='var-DEBUG_BUILD'>DEBUG_BUILD</link></glossterm> = "1" in 
+        local.conf (the latter will also add extra debug information making the
+        debug packages large).

+
+        <para>
+            All the profiling work can be performed on the target device. A 
+            simple OProfile session might look like:
+        </para>
+
+        <para>
+            <literallayout class='monospaced'>
+# opcontrol --reset
+# opcontrol --start --separate=lib --no-vmlinux -c 5
+[do whatever is being profiled]
+# opcontrol --stop
+$ opreport -cl
+</literallayout>
+        </para>
+
+        <para>
+            Here, the reset command clears any previously profiled data, 
+            OProfile is then started. The options used to start OProfile mean
+            dynamic library data is kept separately per application, kernel 
+            profiling is disabled and callgraphing is enabled up to 5 levels 
+            deep. To profile the kernel, you would specify the 
+            <parameter>--vmlinux=/path/to/vmlinux</parameter> option (the vmlinux file is usually in 
+            <filename class="directory">/boot/</filename> in Poky and must match the running kernel). The profile is 
+            then stopped and the results viewed with opreport with options
+            to see the separate library symbols and callgraph information.
+        </para>
+        <para>
+            Callgraphing means OProfile not only logs infomation about which 
+            functions time is being spent in but also which functions
+            called those functions (their parents) and which functions that 
+            function calls (its children). The higher the callgraphing depth, 
+            the more accurate the results but this also increased the loging 
+            overhead so it should be used with caution. On ARM, binaries need 
+            to have the frame pointer enabled for callgraphing to work (compile
+            with the gcc option -fno-omit-framepointer).

+                the sample data, the object files and the debug information for said object
+                files. This archive is then converted using a script included in this
+                distribution ('oparchconv') that uses 'opimport' to convert the archive from
+                the target to something that can be processed on the host.

+                If you wish to profile into the kernel, this is possible, you just need to ensure
+                a vmlinux file matching the running kernel is available. In Poky this is usually 
+                located in /boot/vmlinux-KERNELVERSION, where KERNEL-version is the version of 
+                the kernel e.g. 2.6.23. Poky generates separate vmlinux packages for each kernel
+                it builds so it should be a question of just ensuring a matching package is 
+                installed (<command> ipkg install kernel-vmlinux</command>. These are automatically 
+                installed into development and profiling images alongside OProfile. There is a 
+                configuration option within the OProfileUI settings page where the location of

+            We recognise that people will want to extend/configure/optimise Poky for
+            their specific uses, especially due to the extreme configurability and 
+            flexibility Poky offers. To ensure ease of keeping pace with future

+            Poky supports the idea of <link

+            properly can massively ease future upgrades and allow segregation

+            <para>
+                Often, people want to extend Poky either through adding packages
+                or overriding files contained within Poky to add their own
+                functionality. Bitbake has a powerful mechanism called
+                collections which provide a way to handle this which is fully
+                supported and actively encouraged within Poky.
+            </para>
+            <para>
+                In the standard tree, meta-extras is an example of how you can
+                do this. As standard the data in meta-extras is not used on a
+                Poky build but local.conf.sample shows how to enable it:
+            </para>

+            <para>
+                As can be seen, the extra recipes are added to BBFILES. The
+                BBFILE_COLLECTIONS variable is then set to contain a list of
+                collection names. The BBFILE_PATTERN variables are regular
+                expressions used to match files from BBFILES into a particular
+                collection in this case by using the base pathname. 
+                The BBFILE_PRIORITY variable then assigns the different
+                priorities to the files in different collections. This is useful
+                in situations where the same package might appear in both
+                repositories and allows you to choose which collection should
+                'win'.
+            </para>
+            <para>
+                This works well for recipes. For bbclasses and configuration
+                files, you can use the BBPATH environment variable. In this
+                case, the first file with the matching name found in BBPATH is
+                the one that is used, just like the PATH variable for binaries.

+                Modifications to Poky are often managed under some kind of source
+                revision control system. The policy for committing to such systems
+                is important as some simple policy can significantly improve 
+                usability. The tips below are based on the policy that OpenedHand

+                It helps to use a consistent style for commit messages when committing 
+                changes. We've found a style where the first line of a commit message 
+                summarises the change and starts with the name of any package affected
+                work well. Not all changes are to specific packages so the prefix could 
+                also be a machine name or class name instead. If a change needs a longer

+
+            <para>
+                Any commit should be self contained in that it should leave the

+                commit. This helps ensure the autobuilder test results are valid

+                The second is to ensure that target users are able to upgrade their
+                devices via their package manager such as with the <command>
+                ipkg update;ipkg upgrade</command> commands (or similar for

+            Poky is usually used to build software rather than modifying

+            Where exactly this is depends on the type of package and the

+            After building a package, a user can modify the package source code

+                By default Poky uses <ulink

+                to manage patches in <function>do_patch</function> task.

+            </para>
+
+            <para>
+                Before modifying source code it is important to
+                notify quilt so it will track changes into new patch
+                file:
+                <programlisting>
+quilt new NAME-OF-PATCH.patch
+                </programlisting>
+
+                Then add all files which will be modified into that

+quilt add file1 file2 file3
+                </programlisting>
+
+                Now start editing. At the end quilt needs to be used
+                to generate final patch which will contain all
+                modifications:
+                <programlisting>
+quilt refresh
+                </programlisting>
+

+                (<glossterm><link linkend='var-S'>S</link></glossterm>) directory. For future builds it

+                This also requires a bump of <glossterm><link
+                        linkend='var-PR'>PR</link></glossterm> value in the same recipe as we changed resulting packages.

+
+    <para>
+
+        Poky is an open source platform build tool. It is a complete
+        software development environment for the creation of Linux
+        devices. It aids the design, development, building, debugging,
+        simulation and testing of complete modern software stacks
+        using Linux, the X Window System and GNOME Mobile
+        based application frameworks. It is based on <ulink
+        url='http://openembedded.org/'>OpenEmbedded</ulink> but has
+        been customised with a particular focus.

+
+    <para>
+        Poky is primarily a platform builder which generates filesystem images
+        based on open source software such as the Kdrive X server, the Matchbox
+        window manager, the GTK+ toolkit and the D-Bus message bus system. Images
+        for many kinds of devices can be generated, however the standard example
+        machines target QEMU full system emulation (both x86 and ARM) and the ARM based
+        Sharp Zaurus series of devices. Poky's ability to boot inside a QEMU
+        emulator makes it particularly suitable as a test platform for development
+        of embedded software.
+    </para>
+
+    <para>
+        An important component integrated within Poky is Sato, a GNOME Mobile 
+        based user interface environment.
+        It is designed to work well with screens at very high DPI and restricted
+        size, such as those often found on smartphones and PDAs. It is coded with
+        focus on efficiency and speed so that it works smoothly on hand-held and
+        other embedded hardware. It will sit neatly on top of any device
+        using the GNOME Mobile stack, providing a well defined user experience.

+        of the components that make up Poky followed by information about using and
+        debugging the Poky build system. The <link linkend='extendpoky'>'Extending Poky' section</link> 
+        gives information about how to extend and customise Poky along with advice

+        hardware for common platform development tasks such as software development, 
+        debugging and profiling. The rest of the manual

+        We recommend Debian-based distributions, in particular a recent Ubuntu

+        distribution specific and
+        other distributions will most likely work as long as the appropriate
+        prerequisites are installed - we know of Poky being used successfully on Redhat,
+        SUSE, Gentoo and Slackware host systems.

+Installation Instructions
+*************************
+
+Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005 Free
+Software Foundation, Inc.
+
+This file is free documentation; the Free Software Foundation gives
+unlimited permission to copy, distribute and modify it.
+
+Basic Installation
+==================
+
+These are generic installation instructions.
+
+   The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions.  Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+   It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring.  (Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.)
+
+   If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release.  If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+   The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'.  You only need
+`configure.ac' if you want to change it or regenerate `configure' using
+a newer version of `autoconf'.
+
+The simplest way to compile this package is:
+
+  1. `cd' to the directory containing the package's source code and type
+     `./configure' to configure the package for your system.  If you're
+     using `csh' on an old version of System V, you might need to type
+     `sh ./configure' instead to prevent `csh' from trying to execute
+     `configure' itself.
+
+     Running `configure' takes awhile.  While running, it prints some
+     messages telling which features it is checking for.
+
+  2. Type `make' to compile the package.
+
+  3. Optionally, type `make check' to run any self-tests that come with
+     the package.
+
+  4. Type `make install' to install the programs and any data files and
+     documentation.
+
+  5. You can remove the program binaries and object files from the
+     source code directory by typing `make clean'.  To also remove the
+     files that `configure' created (so you can compile the package for
+     a different kind of computer), type `make distclean'.  There is
+     also a `make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+Compilers and Options
+=====================
+
+Some systems require unusual options for compilation or linking that the
+`configure' script does not know about.  Run `./configure --help' for
+details on some of the pertinent environment variables.
+
+   You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment.  Here
+is an example:
+
+     ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
+
+   *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'.  `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script.  `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+   If you have to use a `make' that does not support the `VPATH'
+variable, you have to compile the package for one architecture at a
+time in the source code directory.  After you have installed the
+package for one architecture, use `make distclean' before reconfiguring
+for another architecture.
+
+Installation Names
+==================
+
+By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc.  You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX'.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files.  Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System).  The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+There may be some features `configure' cannot figure out automatically,
+but needs to determine by the type of machine the package will run on.
+Usually, assuming the package is built to be run on the _same_
+architectures, `configure' can figure that out, but if it prints a
+message saying it cannot guess the machine type, give it the
+`--build=TYPE' option.  TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+     CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+     OS KERNEL-OS
+
+   See the file `config.sub' for the possible values of each field.  If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+   If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+   If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+If you want to set default values for `configure' scripts to share, you
+can create a site shell script called `config.site' that gives default
+values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists.  Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+Variables not defined in a site shell script can be set in the
+environment passed to `configure'.  However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost.  In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'.  For example:
+
+     ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).  Here is a another example:
+
+     /bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+Here the `CONFIG_SHELL=/bin/bash' operand causes subsequent
+configuration-related scripts to be executed by `/bin/bash'.
+
+`configure' Invocation
+======================
+
+`configure' recognizes the following options to control how it operates.
+
+`--help'
+`-h'
+     Print a summary of the options to `configure', and exit.
+
+`--version'
+`-V'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`--cache-file=FILE'
+     Enable the cache: use and save the results of the tests in FILE,
+     traditionally `config.cache'.  FILE defaults to `/dev/null' to
+     disable caching.
+
+`--config-cache'
+`-C'
+     Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.  To
+     suppress all normal output, redirect it to `/dev/null' (any error
+     messages will still be shown).
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`configure' also accepts some other, not widely useful, options.  Run
+`configure --help' for more details.

+    <title>Reference: Bitbake</title>
+
+    <para>
+        Bitbake a program written in Python which interprets the metadata
+        that makes up Poky. At some point, people wonder what actually happens 
+        when you type <command>bitbake poky-image-sato</command>. This section 
+        aims to give an overview of what happens behind the scenes from a
+        BitBake perspective.
+    </para>
+
+    <para>
+        It is worth noting that bitbake aims to be a generic "task" executor 
+        capable of handling complex dependency relationships. As such it has no 
+        real knowledge of what the tasks its executing actually do. It just 
+        considers a list of tasks with dependencies and handles metadata 
+        consisting of variables in a certain format which get passed to the 
+        tasks.
+    </para>
+
+    <section id='ref-bitbake-parsing'>
+        <title>Parsing</title>
+
+        <para>
+            The first thing BitBake does is work out its configuration by 
+            looking for a file called <filename>bitbake.conf</filename>.
+            Bitbake searches through the <varname>BBPATH</varname> environment 
+            variable looking for a <filename class="directory">conf/</filename> 
+            directory containing a <filename>bitbake.conf</filename> file and 
+            adds the first <filename>bitbake.conf</filename> file found in
+            <varname>BBPATH</varname> (similar to the PATH environment variable). 
+            For Poky, <filename>bitbake.conf</filename> is found in <filename 
+            class="directory">meta/conf/</filename>. 
+        </para>
+
+        <para>
+            In Poky, <filename>bitbake.conf</filename> lists other configuration 
+            files to include from a <filename class="directory">conf/</filename> 
+            directory below the directories listed in <varname>BBPATH</varname>. 
+            In general the most important configuration file from a user's perspective 
+            is <filename>local.conf</filename>, which contains a users customized 
+            settings for Poky. Other notable configuration files are the distribution 
+            configuration file (set by the <glossterm><link linkend='var-DISTRO'>
+            DISTRO</link></glossterm> variable) and the machine configuration file 
+            (set by the <glossterm><link linkend='var-MACHINE'>MACHINE</link>
+            </glossterm> variable).  The <glossterm><link linkend='var-DISTRO'>
+            DISTRO</link></glossterm> and <glossterm><link linkend='var-MACHINE'>
+            MACHINE</link></glossterm> environment variables are both usually set in 
+            the <filename>local.conf</filename> file. Valid distribution 
+            configuration files are available in the <filename class="directory">
+            meta/conf/distro/</filename> directory and valid machine configuration 
+            files in the <filename class="directory">meta/conf/machine/</filename> 
+            directory. Within the <filename class="directory">
+            meta/conf/machine/include/</filename> directory are various <filename>
+            tune-*.inc</filename> configuration files which provide common 
+            "tuning" settings specific to and shared between particular 
+            architectures and machines.
+        </para>
+
+        <para>
+            After the parsing of the configuration files some standard classes 
+            are included. In particular, <filename>base.bbclass</filename> is 
+            always included, as will any other classes 
+            specified in the configuration using the <glossterm><link
+                    linkend='var-INHERIT'>INHERIT</link></glossterm>
+            variable. Class files are searched for in a classes subdirectory 
+            under the paths in <varname>BBPATH</varname> in the same way as
+            configuration files.
+        </para>
+
+        <para>
+            After the parsing of the configuration files is complete, the 
+            variable <glossterm><link linkend='var-BBFILES'>BBFILES</link></glossterm> 
+            is set, usually in
+            <filename>local.conf</filename>, and defines the list of places to search for 
+            <filename class="extension">.bb</filename> files. By 
+            default this specifies the <filename class="directory">meta/packages/
+            </filename> directory within Poky, but other directories such as
+            <filename class="directory">meta-extras/</filename> can be included 
+            too. If multiple directories are specified a system referred to as 
+            <link linkend='usingpoky-changes-collections'>"collections"</link> is used to 
+            determine which files have priority.
+        </para>
+
+        <para>
+            Bitbake parses each <filename class="extension">.bb</filename> file in 
+            <glossterm><link linkend='var-BBFILES'>BBFILES</link></glossterm> and 
+            stores the values of various variables.  In summary, for each 
+            <filename class="extension">.bb</filename> 
+            file the configuration + base class of variables are set, followed 
+            by the data in the <filename class="extension">.bb</filename> file 
+            itself, followed by any inherit commands that
+            <filename class="extension">.bb</filename> file might contain.
+        </para>
+
+        <para>
+            Parsing <filename class="extension">.bb</filename> files is a time 
+            consuming process, so a cache is kept to speed up subsequent parsing. 
+            This cache is invalid if the timestamp of the <filename class="extension">.bb</filename> 
+            file itself has changed, or if the timestamps of any of the include, 
+            configuration or class files the <filename class="extension">.bb</filename>
+            file depends on have changed.
+        </para>
+    </section>
+
+    <section id='ref-bitbake-providers'>
+        <title>Preferences and Providers</title>
+
+        <para>
+            Once all the <filename class="extension">.bb</filename> files have been 
+            parsed, BitBake will proceed to build "poky-image-sato" (or whatever was
+            specified on the commandline) and looks for providers of that target.
+            Once a provider is selected, BitBake resolves all the dependencies for  
+            the target. In the case of "poky-image-sato", it would lead to 
+            <filename>task-oh.bb</filename> and <filename>task-base.bb</filename>  
+            which in turn would lead to packages like <application>Contacts</application>, 
+            <application>Dates</application>, <application>BusyBox</application>
+            and these in turn depend on glibc and the toolchain.
+        </para>
+
+        <para>
+            Sometimes a target might have multiple providers and a common example 
+            is "virtual/kernel" that is provided by each kernel package. Each machine
+            will often elect the best provider of its kernel with a line like the 
+            following in the machine configuration file:
+        </para>
+        <programlisting><glossterm><link linkend='var-PREFERRED_PROVIDER'>PREFERRED_PROVIDER</link></glossterm>_virtual/kernel = "linux-rp"</programlisting>
+        <para>
+            The default <glossterm><link linkend='var-PREFERRED_PROVIDER'>
+            PREFERRED_PROVIDER</link></glossterm> is the provider with the same name as
+            the target.
+        </para>
+
+        <para>
+            Understanding how providers are chosen is complicated by the fact
+            multiple versions might be present. Bitbake defaults to the highest 
+            version of a provider by default. Version comparisons are made using 
+            the same method as Debian. The <glossterm><link 
+            linkend='var-PREFERRED_VERSION'>PREFERRED_VERSION</link></glossterm>
+            variable can be used to specify a particular version 
+            (usually in the distro configuration) but the order can 
+            also be influenced by the <glossterm><link
+                    linkend='var-DEFAULT_PREFERENCE'>DEFAULT_PREFERENCE</link></glossterm> 
+            variable. By default files 
+            have a preference of "0". Setting the
+            <glossterm><link
+                    linkend='var-DEFAULT_PREFERENCE'>DEFAULT_PREFERENCE</link></glossterm> to "-1" will 
+            make a package unlikely to be used unless it was explicitly referenced and
+            "1" makes it likely the package will be used. 
+            <glossterm><link
+                    linkend='var-PREFERRED_VERSION'>PREFERRED_VERSION</link></glossterm> overrides 
+            any default preference. <glossterm><link
+                    linkend='var-DEFAULT_PREFERENCE'>DEFAULT_PREFERENCE</link></glossterm> 
+            is often used to mark more 
+            experimental new versions of packages until they've undergone sufficient 
+            testing to be considered stable.
+        </para>
+
+        <para>
+            The end result is that internally, BitBake has now built a list of 
+            providers for each target it needs in order of priority.
+        </para>

+        <title>Dependencies</title>
+
+        <para>
+            Each target BitBake builds consists of multiple tasks (e.g. fetch, 
+            unpack, patch, configure, compile etc.). For best performance on 
+            multi-core systems, BitBake considers each task as an independent 
+            entity with a set of dependencies. There are many variables that 
+            are used to signify these dependencies and more information can be found 
+            found about these in the <ulink url='http://bitbake.berlios.de/manual/'>

+
+        <para>
+            Based on the generated list of providers and the dependency information, 
+            BitBake can now calculate exactly which tasks it needs to run and in what 
+            order. The build now starts with BitBake forking off threads up to
+            the limit set in the <glossterm><link
+                    linkend='var-BB_NUMBER_THREADS'>BB_NUMBER_THREADS</link></glossterm> variable
+            as long there are tasks ready to run, i.e. tasks with all their
+            dependencies met.
+        </para>
+
+        <para>
+            As each task completes, a timestamp is written to the directory 
+            specified by the <glossterm><link
+                    linkend='var-STAMPS'>STAMPS</link></glossterm> variable (usually 
+            <filename class="directory">build/tmp/stamps/*/</filename>). On

+            directory and will not rerun 
+            tasks its already completed unless a timestamp is found to be invalid. 
+            Currently, invalid timestamps are only considered on a per <filename 
+            class="extension">.bb</filename> file basis so if for example the configure stamp has a timestamp greater than the 
+            compile timestamp for a given target the compile task would rerun but this 
+            has no effect on other providers depending on that target. This could 
+            change or become configurable in future versions of BitBake. Some tasks 
+            are marked as "nostamp" tasks which means no timestamp file will be written

+        <title>Running a Task</title>
+
+        <para>
+            It's worth noting what BitBake does to run a task. A task can either
+            be a shell task or a python task. For shell tasks, BitBake writes a
+            shell script to <filename>${WORKDIR}/temp/run.do_taskname.pid</filename>
+            and then executes the script. The generated
+            shell script contains all the exported variables, and the shell functions 
+            with all variables expanded. Output from the shell script is 
+            sent to the file <filename>${WORKDIR}/temp/log.do_taskname.pid</filename>.
+            Looking at the
+            expanded shell functions in the run file and the output in the log files 
+            is a useful debugging technique.
+        </para>
+
+        <para>
+            Python functions are executed internally to BitBake itself and 
+            logging goes to the controlling terminal. Future versions of BitBake will 
+            write the functions to files in a similar way to shell functions and 
+            logging will also go to the log files in a similar way.

+            As well as the containing the parsing and task/dependency handling

+
+    <para>
+        The packaging classes add support for generating packages from the output
+        from builds. The core generic functionality is in 
+        <filename>package.bbclass</filename>, code specific to particular package 
+        types is contained in various sub classes such as 
+        <filename>package_deb.bbclass</filename> and <filename>package_ipk.bbclass</filename>. 
+        Most users will 
+        want one or more of these classes and this is controlled by the <glossterm>
+        <link linkend='var-PACKAGE_CLASSES'>PACKAGE_CLASSES</link></glossterm> 
+        variable. The first class listed in this  variable will be used for image

+<title>Reference: Directory Structure</title>
+
+<para>
+    Poky consists of several components and understanding what these are

+
+        <para>
+            A copy of BitBake is included within Poky for ease of use, and should 
+            usually match the current BitBake stable release from the BitBake project. 
+            Bitbake, a metadata interpreter, reads the Poky metadata and runs the tasks 
+            defined in the Poky metadata. Failures are usually from the metadata, not 
+            BitBake itself, so most users don't need to worry about BitBake. The 
+            <filename class="directory">bitbake/bin/</filename> directory is placed 
+            into the PATH environment variable by the <link

+        <title><filename class="directory">scripts/</filename></title>
+

+            This directory contains various integration scripts which implement 
+            extra functionality in the Poky environment, such as the QEMU 
+            scripts. This directory is appended to the PATH environment variable by the 
+            <link linkend="structure-core-script">poky-init-build-env</link> script.

+
+        <para>
+            While not part of a checkout, Poky will create this directory as 
+            part of any build. Any downloads are placed in this directory (as 
+            specified by the <glossterm><link linkend='var-DL_DIR'>DL_DIR</link>
+            </glossterm> variable). This directory can be shared between Poky 
+            builds to save downloading files multiple times. SCM checkouts are 
+            also stored here as e.g. <filename class="directory">sources/svn/
+            </filename>, <filename class="directory">sources/cvs/</filename> or 
+            <filename class="directory">sources/git/</filename> and the 
+            sources directory may contain archives of checkouts for various 
+            revisions or dates.
+        </para>
+
+        <para>
+            It's worth noting that BitBake creates <filename class="extension">.md5 
+            </filename> stamp files for downloads. It uses these to mark downloads as 
+            complete as well as for checksum and access accounting purposes. If you add 
+            a file manually to the directory, you need to touch the corresponding 
+            <filename class="extension">.md5</filename> file too.
+        </para>
+
+        <para>
+            This location can be overridden by setting <glossterm><link

+            </filename>. This directory can be shared between builds and even between 
+            machines via NFS, so downloads are only made once, speeding up builds.

+            current working directory. You need to use this before running Poky commands.
+            Internally it uses scripts within the <filename class="directory">scripts/

+            that variable is hardcoded within Poky (e.g. by using '=' instead of '?=').

+
+        <para>
+            This directory contains various subdirectories for each architecture, and each package built by BitBake has its own work directory under the appropriate architecture subdirectory.  All tasks are executed from this work directory.  As an example, the source for a particular package will be unpacked, patched, configured and compiled all within its own work directory.
+        </para>
+
+        <para>
+            It is worth considering the structure of a typical work directory. An 
+            example is the linux-rp kernel, version 2.6.20 r7 on the machine spitz 
+            built within Poky.  For this package a work directory of <filename

+            </link></glossterm>, is created.  Within this directory, the source is 
+            unpacked to linux-2.6.20 and then patched by quilt (see <link 
+            linkend="usingpoky-modifying-packages-quilt">Section 3.5.1</link>).

+            There are other directories generated within <glossterm><link

+            package. Examples of other important classes are 
+            <filename>autotools.bbclass</filename> that in theory allows any 
+            Autotool-enabled package to work with Poky with minimal effort, or 
+            <filename>kernel.bbclass</filename> that contains common code and functions 
+            for working with the linux kernel. Functions like image generation or 
+            packaging also have their specific class files (<filename>image.bbclass
+            </filename>, <filename>rootfs_*.bbclass</filename> and 
+            <filename>package*.bbclass</filename>).

+            This is the core set of configuration files which start from 
+            <filename>bitbake.conf</filename> and from which all other configuration 
+            files are included (see the includes at the end of the file, even 
+            <filename>local.conf</filename> is loaded from there!). While 
+            <filename>bitbake.conf</filename> sets up the defaults, these can often be 
+            overridden by user (<filename>local.conf</filename>), machine or

+            end result is Poky looking for a <filename>spitz.conf</filename> file in this directory. The includes
+            directory contains various data common to multiple machines. If you want to add

+            Any distribution specific configuration is controlled from here. OpenEmbedded 
+            supports multiple distributions of which Poky is one. Poky only contains the 
+            Poky distribution so poky.conf is the main file here.  This includes the 
+            versions and SRCDATES for applications which are configured here. An example of 
+            an alternative configuration is poky-bleeding.conf although this mainly inherits
+            its configuration from Poky itself.

+            Each application (package) Poky can build has an associated .bb file which are 
+            all stored under this directory. Poky finds them through the BBFILES variable 
+            which defaults to packages/*/*.bb. Adding a new piece of software to Poky 
+            consists of adding the appropriate .bb file. The .bb files from OpenEmbedded
+            upstream are usually compatible although they are not supported.

+            can't run tests on a live system. This directory therefore contains a list of 
+            cached results for various architectures which is passed to autoconf.
