+Moving to the Yocto Project 2.2 Release
+=======================================
+
+This section provides migration information for moving to the Yocto
+Project 2.2 Release from the prior release.
+
+.. _migration-2.2-minimum-kernel-version:
+
+Minimum Kernel Version
+----------------------
+
+The minimum kernel version for the target system and for SDK is now
+3.2.0, due to the upgrade to ``glibc 2.24``. Specifically, for
+AArch64-based targets the version is 3.14. For Nios II-based targets,
+the minimum kernel version is 3.19.
+
+.. note::
+
+ For x86 and x86_64, you can reset
+ OLDEST_KERNEL
+ to anything down to 2.6.32 if desired.
+
+.. _migration-2.2-staging-directories-in-sysroot-simplified:
+
+Staging Directories in Sysroot Has Been Simplified
+--------------------------------------------------
+
+The way directories are staged in sysroot has been simplified and
+introduces the new :term:`SYSROOT_DIRS`,
+:term:`SYSROOT_DIRS_NATIVE`, and
+:term:`SYSROOT_DIRS_BLACKLIST`. See the
+`v2 patch series on the OE-Core Mailing
+List <http://lists.openembedded.org/pipermail/openembedded-core/2016-May/121365.html>`__
+for additional information.
+
+.. _migration-2.2-removal-of-old-images-from-tmp-deploy-now-enabled:
+
+Removal of Old Images and Other Files in ``tmp/deploy`` Now Enabled
+-------------------------------------------------------------------
+
+Removal of old images and other files in ``tmp/deploy/`` is now enabled
+by default due to a new staging method used for those files. As a result
+of this change, the ``RM_OLD_IMAGE`` variable is now redundant.
+
+.. _migration-2.2-python-changes:
+
+Python Changes
+--------------
+
+The following changes for Python occurred:
+
+.. _migration-2.2-bitbake-now-requires-python-3.4:
+
+BitBake Now Requires Python 3.4+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+BitBake requires Python 3.4 or greater.
+
+.. _migration-2.2-utf-8-locale-required-on-build-host:
+
+UTF-8 Locale Required on Build Host
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A UTF-8 locale is required on the build host due to Python 3. Since
+C.UTF-8 is not a standard, the default is en_US.UTF-8.
+
+.. _migration-2.2-metadata-now-must-use-python-3-syntax:
+
+Metadata Must Now Use Python 3 Syntax
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The metadata is now required to use Python 3 syntax. For help preparing
+metadata, see any of the many Python 3 porting guides available.
+Alternatively, you can reference the conversion commits for Bitbake and
+you can use :term:`OpenEmbedded-Core (OE-Core)` as a guide for changes. Following are
+particular areas of interest:
+
+ - subprocess command-line pipes needing locale decoding
+
+ - the syntax for octal values changed
+
+ - the ``iter*()`` functions changed name \* iterators now return views, not lists
+
+ - changed names for Python modules
+
+.. _migration-2.2-target-python-recipes-switched-to-python-3:
+
+Target Python Recipes Switched to Python 3
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Most target Python recipes have now been switched to Python 3.
+Unfortunately, systems using RPM as a package manager and providing
+online package-manager support through SMART still require Python 2.
+
+.. note::
+
+ Python 2 and recipes that use it can still be built for the target as
+ with previous versions.
+
+.. _migration-2.2-buildtools-tarball-includes-python-3:
+
+``buildtools-tarball`` Includes Python 3
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+``buildtools-tarball`` now includes Python 3.
+
+.. _migration-2.2-uclibc-replaced-by-musl:
+
+uClibc Replaced by musl
+-----------------------
+
+uClibc has been removed in favor of musl. Musl has matured, is better
+maintained, and is compatible with a wider range of applications as
+compared to uClibc.
+
+.. _migration-2.2-B-no-longer-default-working-directory-for-tasks:
+
+``${B}`` No Longer Default Working Directory for Tasks
+------------------------------------------------------
+
+``${``\ :term:`B`\ ``}`` is no longer the default working
+directory for tasks. Consequently, any custom tasks you define now need
+to either have the
+``[``\ :ref:`dirs <bitbake:bitbake-user-manual/bitbake-user-manual-metadata:variable flags>`\ ``]`` flag
+set, or the task needs to change into the appropriate working directory
+manually (e.g using ``cd`` for a shell task).
+
+.. note::
+
+ The preferred method is to use the
+ [dirs]
+ flag.
+
+.. _migration-2.2-runqemu-ported-to-python:
+
+``runqemu`` Ported to Python
+----------------------------
+
+``runqemu`` has been ported to Python and has changed behavior in some
+cases. Previous usage patterns continue to be supported.
+
+The new ``runqemu`` is a Python script. Machine knowledge is no longer
+hardcoded into ``runqemu``. You can choose to use the ``qemuboot``
+configuration file to define the BSP's own arguments and to make it
+bootable with ``runqemu``. If you use a configuration file, use the
+following form:
+::
+
+ image-name-machine.qemuboot.conf
+
+The configuration file
+enables fine-grained tuning of options passed to QEMU without the
+``runqemu`` script hard-coding any knowledge about different machines.
+Using a configuration file is particularly convenient when trying to use
+QEMU with machines other than the ``qemu*`` machines in
+:term:`OpenEmbedded-Core (OE-Core)`. The ``qemuboot.conf`` file is generated by the
+``qemuboot`` class when the root filesystem is being build (i.e. build
+rootfs). QEMU boot arguments can be set in BSP's configuration file and
+the ``qemuboot`` class will save them to ``qemuboot.conf``.
+
+If you want to use ``runqemu`` without a configuration file, use the
+following command form:
+::
+
+ $ runqemu machine rootfs kernel [options]
+
+Supported machines are as follows:
+
+ - qemuarm
+ - qemuarm64
+ - qemux86
+ - qemux86-64
+ - qemuppc
+ - qemumips
+ - qemumips64
+ - qemumipsel
+ - qemumips64el
+
+Consider the
+following example, which uses the ``qemux86-64`` machine, provides a
+root filesystem, provides an image, and uses the ``nographic`` option: ::
+
+ $ runqemu qemux86-64 tmp/deploy/images/qemux86-64/core-image-minimal-qemux86-64.ext4 tmp/deploy/images/qemux86-64/bzImage nographic
+
+Following is a list of variables that can be set in configuration files
+such as ``bsp.conf`` to enable the BSP to be booted by ``runqemu``:
+
+.. note::
+
+ "QB" means "QEMU Boot".
+
+::
+
+ QB_SYSTEM_NAME: QEMU name (e.g. "qemu-system-i386")
+ QB_OPT_APPEND: Options to append to QEMU (e.g. "-show-cursor")
+ QB_DEFAULT_KERNEL: Default kernel to boot (e.g. "bzImage")
+ QB_DEFAULT_FSTYPE: Default FSTYPE to boot (e.g. "ext4")
+ QB_MEM: Memory (e.g. "-m 512")
+ QB_MACHINE: QEMU machine (e.g. "-machine virt")
+ QB_CPU: QEMU cpu (e.g. "-cpu qemu32")
+ QB_CPU_KVM: Similar to QB_CPU except used for kvm support (e.g. "-cpu kvm64")
+ QB_KERNEL_CMDLINE_APPEND: Options to append to the kernel's -append
+ option (e.g. "console=ttyS0 console=tty")
+ QB_DTB: QEMU dtb name
+ QB_AUDIO_DRV: QEMU audio driver (e.g. "alsa", set it when support audio)
+ QB_AUDIO_OPT: QEMU audio option (e.g. "-soundhw ac97,es1370"), which is used
+ when QB_AUDIO_DRV is set.
+ QB_KERNEL_ROOT: Kernel's root (e.g. /dev/vda)
+ QB_TAP_OPT: Network option for 'tap' mode (e.g.
+ "-netdev tap,id=net0,ifname=@TAP@,script=no,downscript=no -device virtio-net-device,netdev=net0").
+ runqemu will replace "@TAP@" with the one that is used, such as tap0, tap1 ...
+ QB_SLIRP_OPT: Network option for SLIRP mode (e.g. "-netdev user,id=net0 -device virtio-net-device,netdev=net0")
+ QB_ROOTFS_OPT: Used as rootfs (e.g.
+ "-drive id=disk0,file=@ROOTFS@,if=none,format=raw -device virtio-blk-device,drive=disk0").
+ runqemu will replace "@ROOTFS@" with the one which is used, such as
+ core-image-minimal-qemuarm64.ext4.
+ QB_SERIAL_OPT: Serial port (e.g. "-serial mon:stdio")
+ QB_TCPSERIAL_OPT: tcp serial port option (e.g.
+ " -device virtio-serial-device -chardev socket,id=virtcon,port=@PORT@,host=127.0.0.1 -device virtconsole,chardev=virtcon"
+ runqemu will replace "@PORT@" with the port number which is used.
+
+To use ``runqemu``, set :term:`IMAGE_CLASSES` as
+follows and run ``runqemu``:
+
+.. note::
+
+ For command-line syntax, use
+ runqemu help
+ .
+
+::
+
+ IMAGE_CLASSES += "qemuboot"
+
+.. _migration-2.2-default-linker-hash-style-changed:
+
+Default Linker Hash Style Changed
+---------------------------------
+
+The default linker hash style for ``gcc-cross`` is now "sysv" in order
+to catch recipes that are building software without using the
+OpenEmbedded :term:`LDFLAGS`. This change could result in
+seeing some "No GNU_HASH in the elf binary" QA issues when building such
+recipes. You need to fix these recipes so that they use the expected
+``LDFLAGS``. Depending on how the software is built, the build system
+used by the software (e.g. a Makefile) might need to be patched.
+However, sometimes making this fix is as simple as adding the following
+to the recipe:
+::
+
+ TARGET_CC_ARCH += "${LDFLAGS}"
+
+.. _migration-2.2-kernel-image-base-name-no-longer-uses-kernel-imagetype:
+
+``KERNEL_IMAGE_BASE_NAME`` no Longer Uses ``KERNEL_IMAGETYPE``
+--------------------------------------------------------------
+
+The ``KERNEL_IMAGE_BASE_NAME`` variable no longer uses the
+:term:`KERNEL_IMAGETYPE` variable to create the
+image's base name. Because the OpenEmbedded build system can now build
+multiple kernel image types, this part of the kernel image base name as
+been removed leaving only the following:
+::
+
+ KERNEL_IMAGE_BASE_NAME ?= "${PKGE}-${PKGV}-${PKGR}-${MACHINE}-${DATETIME}"
+
+If you have recipes or
+classes that use ``KERNEL_IMAGE_BASE_NAME`` directly, you might need to
+update the references to ensure they continue to work.
+
+.. _migration-2.2-bitbake-changes:
+
+BitBake Changes
+---------------
+
+The following changes took place for BitBake:
+
+- The "goggle" UI and standalone image-writer tool have been removed as
+ they both require GTK+ 2.0 and were not being maintained.
+
+- The Perforce fetcher now supports :term:`SRCREV` for
+ specifying the source revision to use, be it
+ ``${``\ :term:`AUTOREV`\ ``}``, changelist number,
+ p4date, or label, in preference to separate
+ :term:`SRC_URI` parameters to specify these. This
+ change is more in-line with how the other fetchers work for source
+ control systems. Recipes that fetch from Perforce will need to be
+ updated to use ``SRCREV`` in place of specifying the source revision
+ within ``SRC_URI``.
+
+- Some of BitBake's internal code structures for accessing the recipe
+ cache needed to be changed to support the new multi-configuration
+ functionality. These changes will affect external tools that use
+ BitBake's tinfoil module. For information on these changes, see the
+ changes made to the scripts supplied with OpenEmbedded-Core:
+ `1 <http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=189371f8393971d00bca0fceffd67cc07784f6ee>`__
+ and
+ `2 <http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=4a5aa7ea4d07c2c90a1654b174873abb018acc67>`__.
+
+- The task management code has been rewritten to avoid using ID
+ indirection in order to improve performance. This change is unlikely
+ to cause any problems for most users. However, the setscene
+ verification function as pointed to by
+ ``BB_SETSCENE_VERIFY_FUNCTION`` needed to change signature.
+ Consequently, a new variable named ``BB_SETSCENE_VERIFY_FUNCTION2``
+ has been added allowing multiple versions of BitBake to work with
+ suitably written metadata, which includes OpenEmbedded-Core and Poky.
+ Anyone with custom BitBake task scheduler code might also need to
+ update the code to handle the new structure.
+
+.. _migration-2.2-swabber-has-been-removed:
+
+Swabber has Been Removed
+------------------------
+
+Swabber, a tool that was intended to detect host contamination in the
+build process, has been removed, as it has been unmaintained and unused
+for some time and was never particularly effective. The OpenEmbedded
+build system has since incorporated a number of mechanisms including
+enhanced QA checks that mean that there is less of a need for such a
+tool.
+
+.. _migration-2.2-removed-recipes:
+
+Removed Recipes
+---------------
+
+The following recipes have been removed:
+
+- ``augeas``: No longer needed and has been moved to ``meta-oe``.
+
+- ``directfb``: Unmaintained and has been moved to ``meta-oe``.
+
+- ``gcc``: Removed 4.9 version. Versions 5.4 and 6.2 are still present.
+
+- ``gnome-doc-utils``: No longer needed.
+
+- ``gtk-doc-stub``: Replaced by ``gtk-doc``.
+
+- ``gtk-engines``: No longer needed and has been moved to
+ ``meta-gnome``.
+
+- ``gtk-sato-engine``: Became obsolete.
+
+- ``libglade``: No longer needed and has been moved to ``meta-oe``.
+
+- ``libmad``: Unmaintained and functionally replaced by ``libmpg123``.
+ ``libmad`` has been moved to ``meta-oe``.
+
+- ``libowl``: Became obsolete.
+
+- ``libxsettings-client``: No longer needed.
+
+- ``oh-puzzles``: Functionally replaced by ``puzzles``.
+
+- ``oprofileui``: Became obsolete. OProfile has been largely supplanted
+ by perf.
+
+- ``packagegroup-core-directfb.bb``: Removed.
+
+- ``core-image-directfb.bb``: Removed.
+
+- ``pointercal``: No longer needed and has been moved to ``meta-oe``.
+
+- ``python-imaging``: No longer needed and moved to ``meta-python``
+
+- ``python-pyrex``: No longer needed and moved to ``meta-python``.
+
+- ``sato-icon-theme``: Became obsolete.
+
+- ``swabber-native``: Swabber has been removed. See the `entry on
+ Swabber <#migration-2.2-swabber-has-been-removed>`__.
+
+- ``tslib``: No longer needed and has been moved to ``meta-oe``.
+
+- ``uclibc``: Removed in favor of musl.
+
+- ``xtscal``: No longer needed and moved to ``meta-oe``
+
+.. _migration-2.2-removed-classes:
+
+Removed Classes
+---------------
+
+The following classes have been removed:
+
+- ``distutils-native-base``: No longer needed.
+
+- ``distutils3-native-base``: No longer needed.
+
+- ``sdl``: Only set :term:`DEPENDS` and
+ :term:`SECTION`, which are better set within the
+ recipe instead.
+
+- ``sip``: Mostly unused.
+
+- ``swabber``: See the `entry on
+ Swabber <#migration-2.2-swabber-has-been-removed>`__.
+
+.. _migration-2.2-minor-packaging-changes:
+
+Minor Packaging Changes
+-----------------------
+
+The following minor packaging changes have occurred:
+
+- ``grub``: Split ``grub-editenv`` into its own package.
+
+- ``systemd``: Split container and vm related units into a new package,
+ systemd-container.
+
+- ``util-linux``: Moved ``prlimit`` to a separate
+ ``util-linux-prlimit`` package.
+
+.. _migration-2.2-miscellaneous-changes:
+
+Miscellaneous Changes
+---------------------
+
+The following miscellaneous changes have occurred:
+
+- ``package_regex.inc``: Removed because the definitions
+ ``package_regex.inc`` previously contained have been moved to their
+ respective recipes.
+
+- Both ``devtool add`` and ``recipetool create`` now use a fixed
+ :term:`SRCREV` by default when fetching from a Git
+ repository. You can override this in either case to use
+ ``${``\ :term:`AUTOREV`\ ``}`` instead by using the
+ ``-a`` or ``DASHDASHautorev`` command-line option
+
+- ``distcc``: GTK+ UI is now disabled by default.
+
+- ``packagegroup-core-tools-testapps``: Removed Piglit.
+
+- ``image.bbclass``: Renamed COMPRESS(ION) to CONVERSION. This change
+ means that ``COMPRESSIONTYPES``, ``COMPRESS_DEPENDS`` and
+ ``COMPRESS_CMD`` are deprecated in favor of ``CONVERSIONTYPES``,
+ ``CONVERSION_DEPENDS`` and ``CONVERSION_CMD``. The ``COMPRESS*``
+ variable names will still work in the 2.2 release but metadata that
+ does not need to be backwards-compatible should be changed to use the
+ new names as the ``COMPRESS*`` ones will be removed in a future
+ release.
+
+- ``gtk-doc``: A full version of ``gtk-doc`` is now made available.
+ However, some old software might not be capable of using the current
+ version of ``gtk-doc`` to build documentation. You need to change
+ recipes that build such software so that they explicitly disable
+ building documentation with ``gtk-doc``.
+
+
