-**********************
-Using the Command Line
-**********************
-
-Recall that earlier the manual discussed how to use an existing
-toolchain tarball that had been installed into the default installation
-directory, ``/opt/poky/DISTRO``, which is outside of the :term:`Build Directory`
-(see the section
-"`Using a Cross-Toolchain
-Tarball) <#using-an-existing-toolchain-tarball>`__". And, that sourcing
-your architecture-specific environment setup script initializes a
-suitable cross-toolchain development environment.
-
-During this setup, locations for the compiler, QEMU scripts, QEMU
-binary, a special version of ``pkgconfig`` and other useful utilities
-are added to the ``PATH`` variable. Also, variables to assist
-``pkgconfig`` and ``autotools`` are also defined so that, for example,
-``configure.sh`` can find pre-generated test results for tests that need
-target hardware on which to run. You can see the "`Setting Up the
-Cross-Development
-Environment <#setting-up-the-cross-development-environment>`__" section
-for the list of cross-toolchain environment variables established by the
-script.
-
-Collectively, these conditions allow you to easily use the toolchain
-outside of the OpenEmbedded build environment on both Autotools-based
-projects and Makefile-based projects. This chapter provides information
-for both these types of projects.
-
-Autotools-Based Projects
-========================
-
-Once you have a suitable cross-toolchain installed, it is very easy to
-develop a project outside of the OpenEmbedded build system. This section
-presents a simple "Helloworld" example that shows how to set up,
-compile, and run the project.
-
-Creating and Running a Project Based on GNU Autotools
------------------------------------------------------
-
-Follow these steps to create a simple Autotools-based project:
-
-1.  *Create your directory:* Create a clean directory for your project
-    and then make that directory your working location: $ mkdir
-    $HOME/helloworld $ cd $HOME/helloworld
-
-2.  *Populate the directory:* Create ``hello.c``, ``Makefile.am``, and
-    ``configure.in`` files as follows:
-
-    -  For ``hello.c``, include these lines: #include <stdio.h> main() {
-       printf("Hello World!\n"); }
-
-    -  For ``Makefile.am``, include these lines: bin_PROGRAMS = hello
-       hello_SOURCES = hello.c
-
-    -  For ``configure.in``, include these lines: AC_INIT(hello.c)
-       AM_INIT_AUTOMAKE(hello,0.1) AC_PROG_CC AC_PROG_INSTALL
-       AC_OUTPUT(Makefile)
-
-3.  *Source the cross-toolchain environment setup file:* Installation of
-    the cross-toolchain creates a cross-toolchain environment setup
-    script in the directory that the ADT was installed. Before you can
-    use the tools to develop your project, you must source this setup
-    script. The script begins with the string "environment-setup" and
-    contains the machine architecture, which is followed by the string
-    "poky-linux". Here is an example that sources a script from the
-    default ADT installation directory that uses the 32-bit Intel x86
-    Architecture and the DISTRO_NAME Yocto Project release: $ source
-    /opt/poky/DISTRO/environment-setup-i586-poky-linux
-
-4.  *Generate the local aclocal.m4 files and create the configure
-    script:* The following GNU Autotools generate the local
-    ``aclocal.m4`` files and create the configure script: $ aclocal $
-    autoconf
-
-5.  *Generate files needed by GNU coding standards:* GNU coding
-    standards require certain files in order for the project to be
-    compliant. This command creates those files: $ touch NEWS README
-    AUTHORS ChangeLog
-
-6.  *Generate the configure file:* This command generates the
-    ``configure``: $ automake -a
-
-7.  *Cross-compile the project:* This command compiles the project using
-    the cross-compiler. The
-    :term:`CONFIGURE_FLAGS`
-    environment variable provides the minimal arguments for GNU
-    configure: $ ./configure ${CONFIGURE_FLAGS}
-
-8.  *Make and install the project:* These two commands generate and
-    install the project into the destination directory: $ make $ make
-    install DESTDIR=./tmp
-
-9.  *Verify the installation:* This command is a simple way to verify
-    the installation of your project. Running the command prints the
-    architecture on which the binary file can run. This architecture
-    should be the same architecture that the installed cross-toolchain
-    supports. $ file ./tmp/usr/local/bin/hello
-
-10. *Execute your project:* To execute the project in the shell, simply
-    enter the name. You could also copy the binary to the actual target
-    hardware and run the project there as well: $ ./hello As expected,
-    the project displays the "Hello World!" message.
-
-Passing Host Options
---------------------
-
-For an Autotools-based project, you can use the cross-toolchain by just
-passing the appropriate host option to ``configure.sh``. The host option
-you use is derived from the name of the environment setup script found
-in the directory in which you installed the cross-toolchain. For
-example, the host option for an ARM-based target that uses the GNU EABI
-is ``armv5te-poky-linux-gnueabi``. You will notice that the name of the
-script is ``environment-setup-armv5te-poky-linux-gnueabi``. Thus, the
-following command works to update your project and rebuild it using the
-appropriate cross-toolchain tools: $ ./configure
---host=armv5te-poky-linux-gnueabi \\ --with-libtool-sysroot=sysroot_dir
-
-.. note::
-
-   If the
-   configure
-   script results in problems recognizing the
-   --with-libtool-sysroot=
-   sysroot-dir
-   option, regenerate the script to enable the support by doing the
-   following and then run the script again:
-   ::
-
-           $ libtoolize --automake
-           $ aclocal -I ${OECORE_NATIVE_SYSROOT}/usr/share/aclocal \
-              [-I dir_containing_your_project-specific_m4_macros]
-           $ autoconf
-           $ autoheader
-           $ automake -a
-                      
-
-Makefile-Based Projects
-=======================
-
-For Makefile-based projects, the cross-toolchain environment variables
-established by running the cross-toolchain environment setup script are
-subject to general ``make`` rules.
-
-To illustrate this, consider the following four cross-toolchain
-environment variables:
-:term:`CC`\ =i586-poky-linux-gcc -m32
--march=i586 --sysroot=/opt/poky/1.8/sysroots/i586-poky-linux
-:term:`LD`\ =i586-poky-linux-ld
---sysroot=/opt/poky/1.8/sysroots/i586-poky-linux
-:term:`CFLAGS`\ =-O2 -pipe -g
--feliminate-unused-debug-types
-:term:`CXXFLAGS`\ =-O2 -pipe -g
--feliminate-unused-debug-types Now, consider the following three cases:
-
--  *Case 1 - No Variables Set in the ``Makefile``:* Because these
-   variables are not specifically set in the ``Makefile``, the variables
-   retain their values based on the environment.
-
--  *Case 2 - Variables Set in the ``Makefile``:* Specifically setting
-   variables in the ``Makefile`` during the build results in the
-   environment settings of the variables being overwritten.
-
--  *Case 3 - Variables Set when the ``Makefile`` is Executed from the
-   Command Line:* Executing the ``Makefile`` from the command line
-   results in the variables being overwritten with command-line content
-   regardless of what is being set in the ``Makefile``. In this case,
-   environment variables are not considered unless you use the "-e" flag
-   during the build: $ make -e file If you use this flag, then the
-   environment values of the variables override any variables
-   specifically set in the ``Makefile``.
-
-.. note::
-
-   For the list of variables set up by the cross-toolchain environment
-   setup script, see the "
-   Setting Up the Cross-Development Environment
-   " section.

-*****************************************
-The Application Development Toolkit (ADT)
-*****************************************
-
-Part of the Yocto Project development solution is an Application
-Development Toolkit (ADT). The ADT provides you with a custom-built,
-cross-development platform suited for developing a user-targeted product
-application.
-
-Fundamentally, the ADT consists of the following:
-
--  An architecture-specific cross-toolchain and matching sysroot both
-   built by the :term:`OpenEmbedded Build System`.
-   The toolchain and
-   sysroot are based on a `Metadata <&YOCTO_DOCS_DEV_URL;#metadata>`__
-   configuration and extensions, which allows you to cross-develop on
-   the host machine for the target hardware.
-
--  The Eclipse IDE Yocto Plug-in.
-
--  The Quick EMUlator (QEMU), which lets you simulate target hardware.
-
--  Various user-space tools that greatly enhance your application
-   development experience.
-
-The Cross-Development Toolchain
-===============================
-
-The `Cross-Development
-Toolchain <&YOCTO_DOCS_DEV_URL;#cross-development-toolchain>`__ consists
-of a cross-compiler, cross-linker, and cross-debugger that are used to
-develop user-space applications for targeted hardware. This toolchain is
-created either by running the ADT Installer script, a toolchain
-installer script, or through a :term:`Build Directory`
-that is based on
-your Metadata configuration or extension for your targeted device. The
-cross-toolchain works with a matching target sysroot.
-
-Sysroot
-=======
-
-The matching target sysroot contains needed headers and libraries for
-generating binaries that run on the target architecture. The sysroot is
-based on the target root filesystem image that is built by the
-OpenEmbedded build system and uses the same Metadata configuration used
-to build the cross-toolchain.
-
-.. _eclipse-overview:
-
-Eclipse Yocto Plug-in
-=====================
-
-The Eclipse IDE is a popular development environment and it fully
-supports development using the Yocto Project. When you install and
-configure the Eclipse Yocto Project Plug-in into the Eclipse IDE, you
-maximize your Yocto Project experience. Installing and configuring the
-Plug-in results in an environment that has extensions specifically
-designed to let you more easily develop software. These extensions allow
-for cross-compilation, deployment, and execution of your output into a
-QEMU emulation session. You can also perform cross-debugging and
-profiling. The environment also supports a suite of tools that allows
-you to perform remote profiling, tracing, collection of power data,
-collection of latency data, and collection of performance data.
-
-For information about the application development workflow that uses the
-Eclipse IDE and for a detailed example of how to install and configure
-the Eclipse Yocto Project Plug-in, see the "`Working Within
-Eclipse <&YOCTO_DOCS_DEV_URL;#adt-eclipse>`__" section of the Yocto
-Project Development Manual.
-
-The QEMU Emulator
-=================
-
-The QEMU emulator allows you to simulate your hardware while running
-your application or image. QEMU is made available a number of ways:
-
--  If you use the ADT Installer script to install ADT, you can specify
-   whether or not to install QEMU.
-
--  If you have cloned the ``poky`` Git repository to create a
-   :term:`Source Directory` and you have
-   sourced the environment setup script, QEMU is installed and
-   automatically available.
-
--  If you have downloaded a Yocto Project release and unpacked it to
-   create a :term:`Source Directory`
-   and you have sourced the environment setup script, QEMU is installed
-   and automatically available.
-
--  If you have installed the cross-toolchain tarball and you have
-   sourced the toolchain's setup environment script, QEMU is also
-   installed and automatically available.
-
-User-Space Tools
-================
-
-User-space tools are included as part of the Yocto Project. You will
-find these tools helpful during development. The tools include
-LatencyTOP, PowerTOP, OProfile, Perf, SystemTap, and Lttng-ust. These
-tools are common development tools for the Linux platform.
-
--  *LatencyTOP:* LatencyTOP focuses on latency that causes skips in
-   audio, stutters in your desktop experience, or situations that
-   overload your server even when you have plenty of CPU power left.
-
--  *PowerTOP:* Helps you determine what software is using the most
-   power. You can find out more about PowerTOP at
-   https://01.org/powertop/.
-
--  *OProfile:* A system-wide profiler for Linux systems that is capable
-   of profiling all running code at low overhead. You can find out more
-   about OProfile at http://oprofile.sourceforge.net/about/. For
-   examples on how to setup and use this tool, see the
-   "`OProfile <&YOCTO_DOCS_PROF_URL;#profile-manual-oprofile>`__"
-   section in the Yocto Project Profiling and Tracing Manual.
-
--  *Perf:* Performance counters for Linux used to keep track of certain
-   types of hardware and software events. For more information on these
-   types of counters see https://perf.wiki.kernel.org/. For
-   examples on how to setup and use this tool, see the
-   "`perf <&YOCTO_DOCS_PROF_URL;#profile-manual-perf>`__" section in the
-   Yocto Project Profiling and Tracing Manual.
-
--  *SystemTap:* A free software infrastructure that simplifies
-   information gathering about a running Linux system. This information
-   helps you diagnose performance or functional problems. SystemTap is
-   not available as a user-space tool through the Eclipse IDE Yocto
-   Plug-in. See http://sourceware.org/systemtap for more
-   information on SystemTap. For examples on how to setup and use this
-   tool, see the
-   "`SystemTap <&YOCTO_DOCS_PROF_URL;#profile-manual-systemtap>`__"
-   section in the Yocto Project Profiling and Tracing Manual.
-
--  *Lttng-ust:* A User-space Tracer designed to provide detailed
-   information on user-space activity. See http://lttng.org/ust
-   for more information on Lttng-ust.

-Introduction
-************
-
-Welcome to the Yocto Project Application Developer's Guide. This manual
-provides information that lets you begin developing applications using
-the Yocto Project.
-
-The Yocto Project provides an application development environment based
-on an Application Development Toolkit (ADT) and the availability of
-stand-alone cross-development toolchains and other tools. This manual
-describes the ADT and how you can configure and install it, how to
-access and use the cross-development toolchains, how to customize the
-development packages installation, how to use command-line development
-for both Autotools-based and Makefile-based projects, and an
-introduction to the Eclipse IDE Yocto Plug-in.
-
-.. note::
-
-   The ADT is distribution-neutral and does not require the Yocto
-   Project reference distribution, which is called Poky. This manual,
-   however, uses examples that use the Poky distribution.

-************************************************************
-Optionally Customizing the Development Packages Installation
-************************************************************
-
-Because the Yocto Project is suited for embedded Linux development, it
-is likely that you will need to customize your development packages
-installation. For example, if you are developing a minimal image, then
-you might not need certain packages (e.g. graphics support packages).
-Thus, you would like to be able to remove those packages from your
-target sysroot.
-
-Package Management Systems
-==========================
-
-The OpenEmbedded build system supports the generation of sysroot files
-using three different Package Management Systems (PMS):
-
--  *OPKG:* A less well known PMS whose use originated in the
-   OpenEmbedded and OpenWrt embedded Linux projects. This PMS works with
-   files packaged in an ``.ipk`` format. See
-   http://en.wikipedia.org/wiki/Opkg for more information about
-   OPKG.
-
--  *RPM:* A more widely known PMS intended for GNU/Linux distributions.
-   This PMS works with files packaged in an ``.rpm`` format. The build
-   system currently installs through this PMS by default. See
-   http://en.wikipedia.org/wiki/RPM_Package_Manager for more
-   information about RPM.
-
--  *Debian:* The PMS for Debian-based systems is built on many PMS
-   tools. The lower-level PMS tool ``dpkg`` forms the base of the Debian
-   PMS. For information on dpkg see
-   http://en.wikipedia.org/wiki/Dpkg.
-
-Configuring the PMS
-===================
-
-Whichever PMS you are using, you need to be sure that the
-:term:`PACKAGE_CLASSES`
-variable in the ``conf/local.conf`` file is set to reflect that system.
-The first value you choose for the variable specifies the package file
-format for the root filesystem at sysroot. Additional values specify
-additional formats for convenience or testing. See the
-``conf/local.conf`` configuration file for details.
-
-.. note::
-
-   For build performance information related to the PMS, see the "
-   package.bbclass
-   " section in the Yocto Project Reference Manual.
-
-As an example, consider a scenario where you are using OPKG and you want
-to add the ``libglade`` package to the target sysroot.
-
-First, you should generate the IPK file for the ``libglade`` package and
-add it into a working ``opkg`` repository. Use these commands: $ bitbake
-libglade $ bitbake package-index
-
-Next, source the cross-toolchain environment setup script found in the
-:term:`Source Directory`. Follow
-that by setting up the installation destination to point to your sysroot
-as sysroot_dir. Finally, have an OPKG configuration file conf_file that
-corresponds to the ``opkg`` repository you have just created. The
-following command forms should now work: $ opkg-cl –f conf_file -o
-sysroot_dir update $ opkg-cl –f cconf_file -o sysroot_dir \\
---force-overwrite install libglade $ opkg-cl –f cconf_file -o
-sysroot_dir \\ --force-overwrite install libglade-dbg $ opkg-cl –f
-conf_file> -osysroot_dir> \\ --force-overwrite install libglade-dev

-Preparing for Application Development
-*************************************
-
-In order to develop applications, you need set up your host development
-system. Several ways exist that allow you to install cross-development
-tools, QEMU, the Eclipse Yocto Plug-in, and other tools. This chapter
-describes how to prepare for application development.
-
-.. _installing-the-adt:
-
-Installing the ADT and Toolchains
-=================================
-
-The following list describes installation methods that set up varying
-degrees of tool availability on your system. Regardless of the
-installation method you choose, you must ``source`` the cross-toolchain
-environment setup script, which establishes several key environment
-variables, before you use a toolchain. See the "`Setting Up the
-Cross-Development
-Environment <#setting-up-the-cross-development-environment>`__" section
-for more information.
-
-.. note::
-
-   Avoid mixing installation methods when installing toolchains for
-   different architectures. For example, avoid using the ADT Installer
-   to install some toolchains and then hand-installing cross-development
-   toolchains by running the toolchain installer for different
-   architectures. Mixing installation methods can result in situations
-   where the ADT Installer becomes unreliable and might not install the
-   toolchain.
-
-   If you must mix installation methods, you might avoid problems by
-   deleting ``/var/lib/opkg``, thus purging the ``opkg`` package
-   metadata.
-
--  *Use the ADT installer script:* This method is the recommended way to
-   install the ADT because it automates much of the process for you. For
-   example, you can configure the installation to install the QEMU
-   emulator and the user-space NFS, specify which root filesystem
-   profiles to download, and define the target sysroot location.
-
--  *Use an existing toolchain:* Using this method, you select and
-   download an architecture-specific toolchain installer and then run
-   the script to hand-install the toolchain. If you use this method, you
-   just get the cross-toolchain and QEMU - you do not get any of the
-   other mentioned benefits had you run the ADT Installer script.
-
--  *Use the toolchain from within the Build Directory:* If you already
-   have a :term:`Build Directory`,
-   you can build the cross-toolchain within the directory. However, like
-   the previous method mentioned, you only get the cross-toolchain and
-   QEMU - you do not get any of the other benefits without taking
-   separate steps.
-
-Using the ADT Installer
------------------------
-
-To run the ADT Installer, you need to get the ADT Installer tarball, be
-sure you have the necessary host development packages that support the
-ADT Installer, and then run the ADT Installer Script.
-
-For a list of the host packages needed to support ADT installation and
-use, see the "ADT Installer Extras" lists in the "`Required Packages for
-the Host Development
-System <&YOCTO_DOCS_REF_URL;#required-packages-for-the-host-development-system>`__"
-section of the Yocto Project Reference Manual.
-
-Getting the ADT Installer Tarball
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The ADT Installer is contained in the ADT Installer tarball. You can get
-the tarball using either of these methods:
-
--  *Download the Tarball:* You can download the tarball from
-   ` <&YOCTO_ADTINSTALLER_DL_URL;>`__ into any directory.
-
--  *Build the Tarball:* You can use
-   :term:`BitBake` to generate the
-   tarball inside an existing :term:`Build Directory`.
-
-   If you use BitBake to generate the ADT Installer tarball, you must
-   ``source`` the environment setup script
-   (````` <&YOCTO_DOCS_REF_URL;#structure-core-script>`__ or
-   ```oe-init-build-env-memres`` <&YOCTO_DOCS_REF_URL;#structure-memres-core-script>`__)
-   located in the Source Directory before running the ``bitbake``
-   command that creates the tarball.
-
-   The following example commands establish the
-   :term:`Source Directory`, check out the
-   current release branch, set up the build environment while also
-   creating the default Build Directory, and run the ``bitbake`` command
-   that results in the tarball
-   ``poky/build/tmp/deploy/sdk/adt_installer.tar.bz2``:
-
-   .. note::
-
-      Before using BitBake to build the ADT tarball, be sure to make
-      sure your
-      local.conf
-      file is properly configured. See the "
-      User Configuration
-      " section in the Yocto Project Reference Manual for general
-      configuration information.
-
-   $ cd ~ $ git clone git://git.yoctoproject.org/poky $ cd poky $ git
-   checkout -b DISTRO_NAME origin/DISTRO_NAME $ source oe-init-build-env $
-   bitbake adt-installer
-
-Configuring and Running the ADT Installer Script
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Before running the ADT Installer script, you need to unpack the tarball.
-You can unpack the tarball in any directory you wish. For example, this
-command copies the ADT Installer tarball from where it was built into
-the home directory and then unpacks the tarball into a top-level
-directory named ``adt-installer``: $ cd ~ $ cp
-poky/build/tmp/deploy/sdk/adt_installer.tar.bz2 $HOME $ tar -xjf
-adt_installer.tar.bz2 Unpacking it creates the directory
-``adt-installer``, which contains the ADT Installer script
-(``adt_installer``) and its configuration file (``adt_installer.conf``).
-
-Before you run the script, however, you should examine the ADT Installer
-configuration file and be sure you are going to get what you want. Your
-configurations determine which kernel and filesystem image are
-downloaded.
-
-The following list describes the configurations you can define for the
-ADT Installer. For configuration values and restrictions, see the
-comments in the ``adt-installer.conf`` file:
-
--  ``YOCTOADT_REPO``: This area includes the IPKG-based packages and the
-   root filesystem upon which the installation is based. If you want to
-   set up your own IPKG repository pointed to by ``YOCTOADT_REPO``, you
-   need to be sure that the directory structure follows the same layout
-   as the reference directory set up at
-   http://adtrepo.yoctoproject.org. Also, your repository needs
-   to be accessible through HTTP.

-variable also in your configuration file.
-
-.. _using-an-existing-toolchain-tarball:
-
-Using a Cross-Toolchain Tarball
--------------------------------
-
-If you want to simply install a cross-toolchain by hand, you can do so
-by running the toolchain installer. The installer includes the pre-built
-cross-toolchain, the ``runqemu`` script, and support files. If you use
-this method to install the cross-toolchain, you might still need to
-install the target sysroot by installing and extracting it separately.
-For information on how to install the sysroot, see the "`Extracting the
-Root Filesystem <#extracting-the-root-filesystem>`__" section.
-
-Follow these steps:
-
-1. *Get your toolchain installer using one of the following methods:*
-
-   -  Go to ` <&YOCTO_TOOLCHAIN_DL_URL;>`__ and find the folder that
-      matches your host development system (i.e. ``i686`` for 32-bit
-      machines or ``x86_64`` for 64-bit machines).
-
-      Go into that folder and download the toolchain installer whose
-      name includes the appropriate target architecture. The toolchains
-      provided by the Yocto Project are based off of the
-      ``core-image-sato`` image and contain libraries appropriate for
-      developing against that image. For example, if your host
-      development system is a 64-bit x86 system and you are going to use
-      your cross-toolchain for a 32-bit x86 target, go into the
-      ``x86_64`` folder and download the following installer:
-      poky-glibc-x86_64-core-image-sato-i586-toolchain-DISTRO.sh
-
-   -  Build your own toolchain installer. For cases where you cannot use
-      an installer from the download area, you can build your own as
-      described in the "`Optionally Building a Toolchain
-      Installer <#optionally-building-a-toolchain-installer>`__"
-      section.
-
-2. *Once you have the installer, run it to install the toolchain:*
-
-   .. note::
-
-      You must change the permissions on the toolchain installer script
-      so that it is executable.
-
-   The following command shows how to run the installer given a
-   toolchain tarball for a 64-bit x86 development host system and a
-   32-bit x86 target architecture. The example assumes the toolchain
-   installer is located in ``~/Downloads/``. $
-   ~/Downloads/poky-glibc-x86_64-core-image-sato-i586-toolchain-DISTRO.sh
-   The first thing the installer prompts you for is the directory into
-   which you want to install the toolchain. The default directory used
-   is ``/opt/poky/DISTRO``. If you do not have write permissions for the
-   directory into which you are installing the toolchain, the toolchain
-   installer notifies you and exits. Be sure you have write permissions
-   in the directory and run the installer again.
-
-   When the script finishes, the cross-toolchain is installed. You will
-   notice environment setup files for the cross-toolchain in the
-   installation directory.
-
-.. _using-the-toolchain-from-within-the-build-tree:
-
-Using BitBake and the Build Directory
--------------------------------------
-
-A final way of making the cross-toolchain available is to use BitBake to
-generate the toolchain within an existing :term:`Build Directory`.
-This method does
-not install the toolchain into the default ``/opt`` directory. As with
-the previous method, if you need to install the target sysroot, you must
-do that separately as well.
-
-Follow these steps to generate the toolchain into the Build Directory:
-
-1. *Set up the Build Environment:* Source the OpenEmbedded build
-   environment setup script (i.e.
-   ````` <&YOCTO_DOCS_REF_URL;#structure-core-script>`__ or
-   ```oe-init-build-env-memres`` <&YOCTO_DOCS_REF_URL;#structure-memres-core-script>`__)
-   located in the :term:`Source Directory`.
-
-2. *Check your Local Configuration File:* At this point, you should be
-   sure that the :term:`MACHINE`
-   variable in the ``local.conf`` file found in the ``conf`` directory
-   of the Build Directory is set for the target architecture. Comments
-   within the ``local.conf`` file list the values you can use for the
-   ``MACHINE`` variable. If you do not change the ``MACHINE`` variable,
-   the OpenEmbedded build system uses ``qemux86`` as the default target
-   machine when building the cross-toolchain.
-
-   .. note::
-
-      You can populate the Build Directory with the cross-toolchains for
-      more than a single architecture. You just need to edit the
-      MACHINE
-      variable in the
-      local.conf
-      file and re-run the
-      bitbake
-      command.
-
-3. *Make Sure Your Layers are Enabled:* Examine the
-   ``conf/bblayers.conf`` file and make sure that you have enabled all
-   the compatible layers for your target machine. The OpenEmbedded build
-   system needs to be aware of each layer you want included when
-   building images and cross-toolchains. For information on how to
-   enable a layer, see the "`Enabling Your
-   Layer <&YOCTO_DOCS_DEV_URL;#enabling-your-layer>`__" section in the
-   Yocto Project Development Manual.
-
-4. *Generate the Cross-Toolchain:* Run ``bitbake meta-ide-support`` to
-   complete the cross-toolchain generation. Once the ``bitbake`` command
-   finishes, the cross-toolchain is generated and populated within the
-   Build Directory. You will notice environment setup files for the
-   cross-toolchain that contain the string "``environment-setup``" in
-   the Build Directory's ``tmp`` folder.
-
-   Be aware that when you use this method to install the toolchain, you
-   still need to separately extract and install the sysroot filesystem.
-   For information on how to do this, see the "`Extracting the Root
-   Filesystem <#extracting-the-root-filesystem>`__" section.
-
-Setting Up the Cross-Development Environment
-============================================
-
-Before you can develop using the cross-toolchain, you need to set up the
-cross-development environment by sourcing the toolchain's environment
-setup script. If you used the ADT Installer or hand-installed
-cross-toolchain, then you can find this script in the directory you
-chose for installation. For this release, the default installation
-directory is ````. If you installed the toolchain in the
-:term:`Build Directory`, you can find the
-environment setup script for the toolchain in the Build Directory's
-``tmp`` directory.
-
-Be sure to run the environment setup script that matches the
-architecture for which you are developing. Environment setup scripts
-begin with the string "``environment-setup``" and include as part of
-their name the architecture. For example, the toolchain environment
-setup script for a 64-bit IA-based architecture installed in the default
-installation directory would be the following:
-YOCTO_ADTPATH_DIR/environment-setup-x86_64-poky-linux When you run the
-setup script, many environment variables are defined:
-:term:`SDKTARGETSYSROOT` -
-The path to the sysroot used for cross-compilation
-:term:`PKG_CONFIG_PATH` - The
-path to the target pkg-config files
-:term:`CONFIG_SITE` - A GNU
-autoconf site file preconfigured for the target
-:term:`CC` - The minimal command and
-arguments to run the C compiler
-:term:`CXX` - The minimal command and
-arguments to run the C++ compiler
-:term:`CPP` - The minimal command and
-arguments to run the C preprocessor
-:term:`AS` - The minimal command and
-arguments to run the assembler :term:`LD`
-- The minimal command and arguments to run the linker
-:term:`GDB` - The minimal command and
-arguments to run the GNU Debugger
-:term:`STRIP` - The minimal command and
-arguments to run 'strip', which strips symbols
-:term:`RANLIB` - The minimal command
-and arguments to run 'ranlib'
-:term:`OBJCOPY` - The minimal command
-and arguments to run 'objcopy'
-:term:`OBJDUMP` - The minimal command
-and arguments to run 'objdump' :term:`AR`
-- The minimal command and arguments to run 'ar'
-:term:`NM` - The minimal command and
-arguments to run 'nm'
-:term:`TARGET_PREFIX` - The
-toolchain binary prefix for the target tools
-:term:`CROSS_COMPILE` - The
-toolchain binary prefix for the target tools
-:term:`CONFIGURE_FLAGS` - The
-minimal arguments for GNU configure
-:term:`CFLAGS` - Suggested C flags
-:term:`CXXFLAGS` - Suggested C++
-flags :term:`LDFLAGS` - Suggested
-linker flags when you use CC to link
-:term:`CPPFLAGS` - Suggested
-preprocessor flags
-
-Securing Kernel and Filesystem Images
-=====================================
-
-You will need to have a kernel and filesystem image to boot using your
-hardware or the QEMU emulator. Furthermore, if you plan on booting your
-image using NFS or you want to use the root filesystem as the target
-sysroot, you need to extract the root filesystem.
-
-Getting the Images
-------------------
-
-To get the kernel and filesystem images, you either have to build them
-or download pre-built versions. For an example of how to build these
-images, see the "`Buiding
-Images <&YOCTO_DOCS_QS_URL;#qs-buiding-images>`__" section of the Yocto
-Project Quick Start. For an example of downloading pre-build versions,
-see the "`Example Using Pre-Built Binaries and
-QEMU <#using-pre-built>`__" section.
-
-The Yocto Project ships basic kernel and filesystem images for several
-architectures (``x86``, ``x86-64``, ``mips``, ``powerpc``, and ``arm``)
-that you can use unaltered in the QEMU emulator. These kernel images
-reside in the release area - ` <&YOCTO_MACHINES_DL_URL;>`__ and are
-ideal for experimentation using Yocto Project. For information on the
-image types you can build using the OpenEmbedded build system, see the
-":ref:`ref-manual/ref-images:Images`" chapter in the Yocto
-Project Reference Manual.
-
-If you are planning on developing against your image and you are not
-building or using one of the Yocto Project development images (e.g.
-``core-image-*-dev``), you must be sure to include the development
-packages as part of your image recipe.
-
-If you plan on remotely deploying and debugging your application from
-within the Eclipse IDE, you must have an image that contains the Yocto
-Target Communication Framework (TCF) agent (``tcf-agent``). You can do
-this by including the ``eclipse-debug`` image feature.
-
-.. note::
-
-   See the "
-   Image Features
-   " section in the Yocto Project Reference Manual for information on
-   image features.
-
-To include the ``eclipse-debug`` image feature, modify your
-``local.conf`` file in the :term:`Build Directory`
-so that the
-:term:`EXTRA_IMAGE_FEATURES`
-variable includes the "eclipse-debug" feature. After modifying the
-configuration file, you can rebuild the image. Once the image is
-rebuilt, the ``tcf-agent`` will be included in the image and is launched
-automatically after the boot.
-
-Extracting the Root Filesystem
-------------------------------
-
-If you install your toolchain by hand or build it using BitBake and you
-need a root filesystem, you need to extract it separately. If you use
-the ADT Installer to install the ADT, the root filesystem is
-automatically extracted and installed.
-
-Here are some cases where you need to extract the root filesystem:
-
--  You want to boot the image using NFS.
-
--  You want to use the root filesystem as the target sysroot. For
-   example, the Eclipse IDE environment with the Eclipse Yocto Plug-in
-   installed allows you to use QEMU to boot under NFS.
-
--  You want to develop your target application using the root filesystem
-   as the target sysroot.
-
-To extract the root filesystem, first ``source`` the cross-development
-environment setup script to establish necessary environment variables.
-If you built the toolchain in the Build Directory, you will find the
-toolchain environment script in the ``tmp`` directory. If you installed
-the toolchain by hand, the environment setup script is located in
-``/opt/poky/DISTRO``.
-
-After sourcing the environment script, use the ``runqemu-extract-sdk``
-command and provide the filesystem image.
-
-Following is an example. The second command sets up the environment. In
-this case, the setup script is located in the ``/opt/poky/DISTRO``
-directory. The third command extracts the root filesystem from a
-previously built filesystem that is located in the ``~/Downloads``
-directory. Furthermore, this command extracts the root filesystem into
-the ``qemux86-sato`` directory: $ cd ~ $ source
-/opt/poky/DISTRO/environment-setup-i586-poky-linux $ runqemu-extract-sdk
-\\ ~/Downloads/core-image-sato-sdk-qemux86-2011091411831.rootfs.tar.bz2
-\\ $HOME/qemux86-sato You could now point to the target sysroot at
-``qemux86-sato``.
-
-Optionally Building a Toolchain Installer
-=========================================
-
-As an alternative to locating and downloading a toolchain installer, you
-can build the toolchain installer if you have a :term:`Build Directory`.
-
-.. note::
-
-   Although not the preferred method, it is also possible to use
-   bitbake meta-toolchain
-   to build the toolchain installer. If you do use this method, you must
-   separately install and extract the target sysroot. For information on
-   how to install the sysroot, see the "
-   Extracting the Root Filesystem
-   " section.
-
-To build the toolchain installer and populate the SDK image, use the
-following command: $ bitbake image -c populate_sdk The command results
-in a toolchain installer that contains the sysroot that matches your
-target root filesystem.
-
-Another powerful feature is that the toolchain is completely
-self-contained. The binaries are linked against their own copy of
-``libc``, which results in no dependencies on the target system. To
-achieve this, the pointer to the dynamic loader is configured at install
-time since that path cannot be dynamically altered. This is the reason
-for a wrapper around the ``populate_sdk`` archive.
-
-Another feature is that only one set of cross-canadian toolchain
-binaries are produced per architecture. This feature takes advantage of
-the fact that the target hardware can be passed to ``gcc`` as a set of
-compiler options. Those options are set up by the environment script and
-contained in variables such as :term:`CC`
-and :term:`LD`. This reduces the space
-needed for the tools. Understand, however, that a sysroot is still
-needed for every target since those binaries are target-specific.
-
-Remember, before using any BitBake command, you must source the build
-environment setup script (i.e.
-````` <&YOCTO_DOCS_REF_URL;#structure-core-script>`__ or
-```oe-init-build-env-memres`` <&YOCTO_DOCS_REF_URL;#structure-memres-core-script>`__)
-located in the Source Directory and you must make sure your
-``conf/local.conf`` variables are correct. In particular, you need to be
-sure the :term:`MACHINE` variable
-matches the architecture for which you are building and that the
-:term:`SDKMACHINE` variable is
-correctly set if you are building a toolchain designed to run on an
-architecture that differs from your current development host machine
-(i.e. the build machine).
-
-When the ``bitbake`` command completes, the toolchain installer will be
-in ``tmp/deploy/sdk`` in the Build Directory.
-
-.. note::
-
-   By default, this toolchain does not build static binaries. If you
-   want to use the toolchain to build these types of libraries, you need
-   to be sure your image has the appropriate static development
-   libraries. Use the
-   IMAGE_INSTALL
-   variable inside your
-   local.conf
-   file to install the appropriate library packages. Following is an
-   example using
-   glibc
-   static development libraries:
-   ::
-
-           IMAGE_INSTALL_append = " glibc-staticdev"
-                  
-
-Optionally Using an External Toolchain
-======================================
-
-You might want to use an external toolchain as part of your development.
-If this is the case, the fundamental steps you need to accomplish are as
-follows:
-
--  Understand where the installed toolchain resides. For cases where you
-   need to build the external toolchain, you would need to take separate
-   steps to build and install the toolchain.
-
--  Make sure you add the layer that contains the toolchain to your
-   ``bblayers.conf`` file through the
-   :term:`BBLAYERS` variable.
-
--  Set the
-   :term:`EXTERNAL_TOOLCHAIN`
-   variable in your ``local.conf`` file to the location in which you
-   installed the toolchain.
-
-A good example of an external toolchain used with the Yocto Project is
-Mentor Graphics Sourcery G++ Toolchain. You can see information on how
-to use that particular layer in the ``README`` file at
-http://github.com/MentorEmbedded/meta-sourcery/. You can find
-further information by reading about the
-:term:`TCMODE` variable in the Yocto
-Project Reference Manual's variable glossary.
-
-.. _using-pre-built:
-
-Example Using Pre-Built Binaries and QEMU
-=========================================
-
-If hardware, libraries and services are stable, you can get started by
-using a pre-built binary of the filesystem image, kernel, and toolchain
-and run it using the QEMU emulator. This scenario is useful for
-developing application software.
-
-|Using a Pre-Built Image|
-
-For this scenario, you need to do several things:
-
--  Install the appropriate stand-alone toolchain tarball.
-
--  Download the pre-built image that will boot with QEMU. You need to be
-   sure to get the QEMU image that matches your target machine's
-   architecture (e.g. x86, ARM, etc.).
-
--  Download the filesystem image for your target machine's architecture.
-
--  Set up the environment to emulate the hardware and then start the
-   QEMU emulator.
-
-Installing the Toolchain
-------------------------
-
-You can download a tarball installer, which includes the pre-built
-toolchain, the ``runqemu`` script, and support files from the
-appropriate directory under ` <&YOCTO_TOOLCHAIN_DL_URL;>`__. Toolchains
-are available for 32-bit and 64-bit x86 development systems from the
-``i686`` and ``x86_64`` directories, respectively. The toolchains the
-Yocto Project provides are based off the ``core-image-sato`` image and
-contain libraries appropriate for developing against that image. Each
-type of development system supports five or more target architectures.
-
-The names of the tarball installer scripts are such that a string
-representing the host system appears first in the filename and then is
-immediately followed by a string representing the target architecture.
-
-::
-
-        poky-glibc-host_system-image_type-arch-toolchain-release_version.sh
-
-        Where:
-            host_system is a string representing your development system:
-
-                       i686 or x86_64.
-
-            image_type is a string representing the image you wish to
-                   develop a Software Development Toolkit (SDK) for use against.
-                   The Yocto Project builds toolchain installers using the
-                   following BitBake command:
-
-                       bitbake core-image-sato -c populate_sdk
-
-            arch is a string representing the tuned target architecture:
-
-                       i586, x86_64, powerpc, mips, armv7a or armv5te
-
-            release_version is a string representing the release number of the
-                   Yocto Project:
-
-                       DISTRO, DISTRO+snapshot
-               
-
-For example, the following toolchain installer is for a 64-bit
-development host system and a i586-tuned target architecture based off
-the SDK for ``core-image-sato``:
-poky-glibc-x86_64-core-image-sato-i586-toolchain-DISTRO.sh
-
-Toolchains are self-contained and by default are installed into
-``/opt/poky``. However, when you run the toolchain installer, you can
-choose an installation directory.
-
-The following command shows how to run the installer given a toolchain
-tarball for a 64-bit x86 development host system and a 32-bit x86 target
-architecture. You must change the permissions on the toolchain installer
-script so that it is executable.
-
-The example assumes the toolchain installer is located in
-``~/Downloads/``.
-
-.. note::
-
-   If you do not have write permissions for the directory into which you
-   are installing the toolchain, the toolchain installer notifies you
-   and exits. Be sure you have write permissions in the directory and
-   run the installer again.
-
-$ ~/Downloads/poky-glibc-x86_64-core-image-sato-i586-toolchain-DISTRO.sh

-Tarball <&YOCTO_DOCS_ADT_URL;#using-an-existing-toolchain-tarball>`__"
-and "`Using BitBake and the Build
-Directory <&YOCTO_DOCS_ADT_URL;#using-the-toolchain-from-within-the-build-tree>`__"
-sections in the Yocto Project Application Developer's Guide.
-
-Downloading the Pre-Built Linux Kernel
---------------------------------------
-
-You can download the pre-built Linux kernel suitable for running in the
-QEMU emulator from ` <&YOCTO_QEMU_DL_URL;>`__. Be sure to use the kernel
-that matches the architecture you want to simulate. Download areas exist
-for the five supported machine architectures: ``qemuarm``, ``qemumips``,
-``qemuppc``, ``qemux86``, and ``qemux86-64``.
-
-Most kernel files have one of the following forms: \*zImage-qemuarch.bin
-vmlinux-qemuarch.bin Where: arch is a string representing the target
-architecture: x86, x86-64, ppc, mips, or arm.
-
-You can learn more about downloading a Yocto Project kernel in the
-"`Yocto Project Kernel <&YOCTO_DOCS_DEV_URL;#local-kernel-files>`__"
-bulleted item in the Yocto Project Development Manual.
-
-Downloading the Filesystem
---------------------------
-
-You can also download the filesystem image suitable for your target
-architecture from ` <&YOCTO_QEMU_DL_URL;>`__. Again, be sure to use the
-filesystem that matches the architecture you want to simulate.
-
-The filesystem image has two tarball forms: ``ext3`` and ``tar``. You
-must use the ``ext3`` form when booting an image using the QEMU
-emulator. The ``tar`` form can be flattened out in your host development
-system and used for build purposes with the Yocto Project.
-core-image-profile-qemuarch.ext3 core-image-profile-qemuarch.tar.bz2
-Where: profile is the filesystem image's profile: lsb, lsb-dev, lsb-sdk,
-lsb-qt3, minimal, minimal-dev, sato, sato-dev, or sato-sdk. For
-information on these types of image profiles, see the
-":ref:`ref-manual/ref-images:Images`" chapter in the Yocto
-Project Reference Manual. arch is a string representing the target
-architecture: x86, x86-64, ppc, mips, or arm.
-
-Setting Up the Environment and Starting the QEMU Emulator
----------------------------------------------------------
-
-Before you start the QEMU emulator, you need to set up the emulation
-environment. The following command form sets up the emulation
-environment. $ source
-YOCTO_ADTPATH_DIR/environment-setup-arch-poky-linux-if Where: arch is a
-string representing the target architecture: i586, x86_64, ppc603e,
-mips, or armv5te. if is a string representing an embedded application
-binary interface. Not all setup scripts include this string.
-
-Finally, this command form invokes the QEMU emulator $ runqemu qemuarch
-kernel-image filesystem-image Where: qemuarch is a string representing
-the target architecture: qemux86, qemux86-64, qemuppc, qemumips, or
-qemuarm. kernel-image is the architecture-specific kernel image.
-filesystem-image is the .ext3 filesystem image.
-
-Continuing with the example, the following two commands setup the
-emulation environment and launch QEMU. This example assumes the root
-filesystem (``.ext3`` file) and the pre-built kernel image file both
-reside in your home directory. The kernel and filesystem are for a
-32-bit target architecture. $ cd $HOME $ source
-YOCTO_ADTPATH_DIR/environment-setup-i586-poky-linux $ runqemu qemux86
-bzImage-qemux86.bin \\ core-image-sato-qemux86.ext3
-
-The environment in which QEMU launches varies depending on the
-filesystem image and on the target architecture. For example, if you
-source the environment for the ARM target architecture and then boot the
-minimal QEMU image, the emulator comes up in a new shell in command-line
-mode. However, if you boot the SDK image, QEMU comes up with a GUI.
-
-.. note::
-
-   Booting the PPC image results in QEMU launching in the same shell in
-   command-line mode.

+
+The fix in 7e05773767820b441b23a16628b55c98cb1aef46 introduced a PLT
+for conditional jumps when the target symbol is undefined.  This is
+incorrect because conditional branch relocations are not allowed to
+clobber IP0/IP1 and hence, should not result in a dynamic relocation.
+
+Revert that change and in its place, issue an error when the target
+symbol is undefined.

+Fixed bug 5146 - SDL_RenderFillRect doesn't work in DirectFB
+
+Lacky
+
+It looks like refactoring of SDL2 internal API has broken SDL_RenderFillRect for DirectFB. In new version function SDL_RenderFillRect returns 0, but rectangle is not visible.
+
+Replacing "count" with "len" in the argument list for SDL_memcpy in DirectFB_QueueFillRects fixes problem.

-Subject: [PATCH 01/10] Kconfig: fix dependency issue when building in-tree
- without CONFIG_FTRACE
-
-When building in-tree, one could disable CONFIG_FTRACE from kernel
-config which will leave CONFIG_TRACEPOINTS selected by LTTNG modules,
-but generate a lot of linker errors like below because it leaves out
-other stuff, e.g.:
-
-trace.c:(.text+0xd86b): undefined reference to `trace_event_buffer_reserve'
-ld: trace.c:(.text+0xd8de): undefined reference to `trace_event_buffer_commit'
-ld: trace.c:(.text+0xd926): undefined reference to `event_triggers_call'
-ld: trace.c:(.text+0xd942): undefined reference to `trace_event_ignore_this_pid'
-ld: net/mac80211/trace.o: in function `trace_event_raw_event_drv_tdls_cancel_channel_switch':
-
-It appears to be caused by the fact that TRACE_EVENT macros in the Linux
-kernel depend on the Ftrace ring buffer as soon as CONFIG_TRACEPOINTS is
-enabled.
-
-Steps to reproduce:
-
-- Get a clone of an upstream stable kernel and use scripts/built-in.sh on it
-
-- Configure a standard x86-64 build, enable built-in LTTNG but disable
-  CONFIG_FTRACE from Kernel Hacking-->Tracers using menuconfig
-
-- Build will fail at linking stage

+Subject: [PATCH 04/11] fix: btrfs: tracepoints: output proper root owner for
+ trace_find_free_extent() (v5.10)
+
+See upstream commit :
+
+  commit 437490fed3b0c9ae21af8f70e0f338d34560842b
+  Author: Qu Wenruo <wqu@suse.com>
+  Date:   Tue Jul 28 09:42:49 2020 +0800
+
+    btrfs: tracepoints: output proper root owner for trace_find_free_extent()
+
+    The current trace event always output result like this:
+
+     find_free_extent: root=2(EXTENT_TREE) len=16384 empty_size=0 flags=4(METADATA)
+     find_free_extent: root=2(EXTENT_TREE) len=16384 empty_size=0 flags=4(METADATA)
+     find_free_extent: root=2(EXTENT_TREE) len=8192 empty_size=0 flags=1(DATA)
+     find_free_extent: root=2(EXTENT_TREE) len=8192 empty_size=0 flags=1(DATA)
+     find_free_extent: root=2(EXTENT_TREE) len=4096 empty_size=0 flags=1(DATA)
+     find_free_extent: root=2(EXTENT_TREE) len=4096 empty_size=0 flags=1(DATA)
+
+    T's saying we're allocating data extent for EXTENT tree, which is not
+    even possible.
+
+    It's because we always use EXTENT tree as the owner for
+    trace_find_free_extent() without using the @root from
+    btrfs_reserve_extent().
+
+    This patch will change the parameter to use proper @root for
+    trace_find_free_extent():
+
+    Now it looks much better:
+
+     find_free_extent: root=5(FS_TREE) len=16384 empty_size=0 flags=36(METADATA|DUP)
+     find_free_extent: root=5(FS_TREE) len=8192 empty_size=0 flags=1(DATA)
+     find_free_extent: root=5(FS_TREE) len=16384 empty_size=0 flags=1(DATA)
+     find_free_extent: root=5(FS_TREE) len=4096 empty_size=0 flags=1(DATA)
+     find_free_extent: root=5(FS_TREE) len=8192 empty_size=0 flags=1(DATA)
+     find_free_extent: root=5(FS_TREE) len=16384 empty_size=0 flags=36(METADATA|DUP)
+     find_free_extent: root=7(CSUM_TREE) len=16384 empty_size=0 flags=36(METADATA|DUP)
+     find_free_extent: root=2(EXTENT_TREE) len=16384 empty_size=0 flags=36(METADATA|DUP)
+     find_free_extent: root=1(ROOT_TREE) len=16384 empty_size=0 flags=36(METADATA|DUP)

-    ext4: limit the length of per-inode prealloc list
-
-    In the scenario of writing sparse files, the per-inode prealloc list may
-    be very long, resulting in high overhead for ext4_mb_use_preallocated().
-    To circumvent this problem, we limit the maximum length of per-inode
-    prealloc list to 512 and allow users to modify it.
-
-    After patching, we observed that the sys ratio of cpu has dropped, and
-    the system throughput has increased significantly. We created a process
-    to write the sparse file, and the running time of the process on the
-    fixed kernel was significantly reduced, as follows:
-
-    Running time on unfixed kernel：
-    [root@TENCENT64 ~]# time taskset 0x01 ./sparse /data1/sparce.dat
-    real    0m2.051s
-    user    0m0.008s
-    sys     0m2.026s
-
-    Running time on fixed kernel：
-    [root@TENCENT64 ~]# time taskset 0x01 ./sparse /data1/sparce.dat
-    real    0m0.471s
-    user    0m0.004s
-    sys     0m0.395s

-    The only use of I_DIRTY_TIME_EXPIRE is to detect in

-    decided it's time to writeback the dirty inode time stamps (either

-    writeback: Fix sync livelock due to b_dirty_time processing
-
-    When we are processing writeback for sync(2), move_expired_inodes()
-    didn't set any inode expiry value (older_than_this). This can result in
-    writeback never completing if there's steady stream of inodes added to
-    b_dirty_time list as writeback rechecks dirty lists after each writeback
-    round whether there's more work to be done. Fix the problem by using
-    sync(2) start time is inode expiry value when processing b_dirty_time
-    list similarly as for ordinarily dirtied inodes. This requires some
-    refactoring of older_than_this handling which simplifies the code
-    noticeably as a bonus.

-Subject: [PATCH 10/10] Fix: system call filter table
-
-The system call filter table has effectively been unused for a long
-time due to system call name prefix mismatch. This means the overhead of
-selective system call tracing was larger than it should have been because
-the event payload preparation would be done for all system calls as soon
-as a single system call is traced.
-
-However, fixing this underlying issue unearths several issues that crept
-unnoticed when the "enabler" concept was introduced (after the original
-implementation of the system call filter table).
-
-Here is a list of the issues which are resolved here:
-
-- Split lttng_syscalls_unregister into an unregister and destroy
-  function, thus awaiting for a grace period (and therefore quiescence
-  of the users) after unregistering the system call tracepoints before
-  freeing the system call filter data structures. This effectively fixes
-  a use-after-free.
-
-- The state for enabling "all" system calls vs enabling specific system
-  calls (and sequences of enable-disable) was incorrect with respect to
-  the "enablers" semantic. This is solved by always tracking the
-  bitmap of enabled system calls, and keeping this bitmap even when
-  enabling all system calls. The sc_filter is now always allocated
-  before system call tracing is registered to tracepoints, which means
-  it does not need to be RCU dereferenced anymore.
-
-Padding fields in the ABI are reserved to select whether to:
-
-- Trace either native or compat system call (or both, which is the
-  behavior currently implemented),
