-Moving to the Yocto Project 2.6 Release (thud)
-==============================================
-
-This section provides migration information for moving to the Yocto
-Project 2.6 Release (codename "thud") from the prior release.
-
-.. _migration-2.6-gcc-changes:
-
-GCC 8.2 is Now Used by Default
-------------------------------
-
-The GNU Compiler Collection version 8.2 is now used by default for
-compilation. For more information on what has changed in the GCC 8.x
-release, see https://gcc.gnu.org/gcc-8/changes.html.
-
-If you still need to compile with version 7.x, GCC 7.3 is also provided.
-You can select this version by setting the and can be selected by
-setting the :term:`GCCVERSION` variable to "7.%" in
-your configuration.
-
-.. _migration-2.6-removed-recipes:
-

-
-.. _migration-2.6-packaging-changes:
-
-Packaging Changes
------------------
-
-The following packaging changes have been made:
-
--  *cmake*: ``cmake.m4`` and ``toolchain`` files have been moved to
-   the main package.
-
--  *iptables*: The ``iptables`` modules have been split into
-   separate packages.
-
--  *alsa-lib*: ``libasound`` is now in the main ``alsa-lib`` package
-   instead of ``libasound``.
-
--  *glibc*: ``libnss-db`` is now in its own package along with a
-   ``/var/db/makedbs.sh`` script to update databases.
-
--  *python and python3*: The main package has been removed from
-   the recipe. You must install specific packages or ``python-modules``
-   / ``python3-modules`` for everything.
-
--  *systemtap*: Moved ``systemtap-exporter`` into its own package.
-
-.. _migration-2.6-xorg-protocol-dependencies:
-
-XOrg Protocol dependencies
---------------------------
-
-The ``*proto`` upstream repositories have been combined into one
-"xorgproto" repository. Thus, the corresponding recipes have also been
-combined into a single ``xorgproto`` recipe. Any recipes that depend
-upon the older ``*proto`` recipes need to be changed to depend on the
-newer ``xorgproto`` recipe instead.
-
-For names of recipes removed because of this repository change, see the
-:ref:`ref-manual/migration-2.6:removed recipes` section.
-
-.. _migration-2.6-distutils-distutils3-fetching-dependencies:
-
-``distutils`` and ``distutils3`` Now Prevent Fetching Dependencies During the ``do_configure`` Task
----------------------------------------------------------------------------------------------------
-
-Previously, it was possible for Python recipes that inherited the
-``distutils`` and
-:ref:`distutils3 <ref-classes-distutils3>` classes to fetch code
-during the :ref:`ref-tasks-configure` task to satisfy
-dependencies mentioned in ``setup.py`` if those dependencies were not
-provided in the sysroot (i.e. recipes providing the dependencies were
-missing from :term:`DEPENDS`).
-
-.. note::
-
-   This change affects classes beyond just the two mentioned (i.e.
-   ``distutils`` and ``distutils3``). Any recipe that inherits ``distutils*``
-   classes are affected. For example, the ``setuptools`` and ``setuptools3``
-   recipes are affected since they inherit the ``distutils*`` classes.
-
-Fetching these types of dependencies that are not provided in the
-sysroot negatively affects the ability to reproduce builds. This type of
-fetching is now explicitly disabled. Consequently, any missing
-dependencies in Python recipes that use these classes now result in an
-error during the ``do_configure`` task.
-
-.. _migration-2.6-linux-yocto-configuration-audit-issues-now-correctly-reported:
-
-``linux-yocto`` Configuration Audit Issues Now Correctly Reported
------------------------------------------------------------------
-
-Due to a bug, the kernel configuration audit functionality was not
-writing out any resulting warnings during the build. This issue is now
-corrected. You might notice these warnings now if you have a custom
-kernel configuration with a ``linux-yocto`` style kernel recipe.
-
-.. _migration-2.6-image-kernel-artifact-naming-changes:
-
-Image/Kernel Artifact Naming Changes
-------------------------------------
-
-The following changes have been made:
-
--  Name variables (e.g. :term:`IMAGE_NAME`) use a new
-   ``IMAGE_VERSION_SUFFIX`` variable instead of
-   :term:`DATETIME`. Using ``IMAGE_VERSION_SUFFIX``
-   allows easier and more direct changes.
-
-   The ``IMAGE_VERSION_SUFFIX`` variable is set in the ``bitbake.conf``
-   configuration file as follows::
-
-      IMAGE_VERSION_SUFFIX = "-${DATETIME}"
-
--  Several variables have changed names for consistency::
-
-      Old Variable Name             New Variable Name
-      ========================================================
-      KERNEL_IMAGE_BASE_NAME        KERNEL_IMAGE_NAME
-      KERNEL_IMAGE_SYMLINK_NAME     KERNEL_IMAGE_LINK_NAME
-      MODULE_TARBALL_BASE_NAME      MODULE_TARBALL_NAME
-      MODULE_TARBALL_SYMLINK_NAME   MODULE_TARBALL_LINK_NAME
-      INITRAMFS_BASE_NAME           INITRAMFS_NAME
-
--  The ``MODULE_IMAGE_BASE_NAME`` variable has been removed. The module
-   tarball name is now controlled directly with the
-   :term:`MODULE_TARBALL_NAME` variable.
-
--  The :term:`KERNEL_DTB_NAME` and
-   :term:`KERNEL_DTB_LINK_NAME` variables
-   have been introduced to control kernel Device Tree Binary (DTB)
-   artifact names instead of mangling ``KERNEL_IMAGE_*`` variables.
-
--  The :term:`KERNEL_FIT_NAME` and
-   :term:`KERNEL_FIT_LINK_NAME` variables
-   have been introduced to specify the name of flattened image tree
-   (FIT) kernel images similar to other deployed artifacts.
-
--  The :term:`MODULE_TARBALL_NAME` and
-   :term:`MODULE_TARBALL_LINK_NAME`
-   variable values no longer include the "module-" prefix or ".tgz"
-   suffix. These parts are now hardcoded so that the values are
-   consistent with other artifact naming variables.
-
--  Added the :term:`INITRAMFS_LINK_NAME`
-   variable so that the symlink can be controlled similarly to other
-   artifact types.
-
--  :term:`INITRAMFS_NAME` now uses
-   "${PKGE}-${PKGV}-${PKGR}-${MACHINE}${IMAGE_VERSION_SUFFIX}" instead
-   of "${PV}-${PR}-${MACHINE}-${DATETIME}", which makes it consistent
-   with other variables.
-
-.. _migration-2.6-serial-console-deprecated:
-
-``SERIAL_CONSOLE`` Deprecated
------------------------------
-
-The :term:`SERIAL_CONSOLE` variable has been
-functionally replaced by the
-:term:`SERIAL_CONSOLES` variable for some time.
-With the Yocto Project 2.6 release, ``SERIAL_CONSOLE`` has been
-officially deprecated.
-
-``SERIAL_CONSOLE`` will continue to work as before for the 2.6 release.
-However, for the sake of future compatibility, it is recommended that
-you replace all instances of ``SERIAL_CONSOLE`` with
-``SERIAL_CONSOLES``.
-
-.. note::
-
-   The only difference in usage is that ``SERIAL_CONSOLES``
-   expects entries to be separated using semicolons as compared to
-   ``SERIAL_CONSOLE``, which expects spaces.
-
-.. _migration-2.6-poky-sets-unknown-configure-option-to-qa-error:
-
-Configure Script Reports Unknown Options as Errors
---------------------------------------------------
-
-If the configure script reports an unknown option, this now triggers a
-QA error instead of a warning. Any recipes that previously got away with
-specifying such unknown options now need to be fixed.

-.. _migration-2.6-override-changes:
-
-Override Changes
-----------------
-
-The following changes have occurred:
-
--  The ``virtclass-native`` and ``virtclass-nativesdk`` Overrides Have
-   Been Removed: The ``virtclass-native`` and ``virtclass-nativesdk``
-   overrides have been deprecated since 2012 in favor of
-   ``class-native`` and ``class-nativesdk``, respectively. Both
-   ``virtclass-native`` and ``virtclass-nativesdk`` are now dropped.
-
-   .. note::
-
-      The ``virtclass-multilib-`` overrides for multilib are still valid.
-
--  The ``forcevariable`` Override Now Has a Higher Priority Than
-   ``libc`` Overrides: The ``forcevariable`` override is documented to
-   be the highest priority override. However, due to a long-standing
-   quirk of how :term:`OVERRIDES` is set, the ``libc``
-   overrides (e.g. ``libc-glibc``, ``libc-musl``, and so forth)
-   erroneously had a higher priority. This issue is now corrected.
-
-   It is likely this change will not cause any problems. However, it is
-   possible with some unusual configurations that you might see a change
-   in behavior if you were relying on the previous behavior. Be sure to
-   check how you use ``forcevariable`` and ``libc-*`` overrides in your
-   custom layers and configuration files to ensure they make sense.
-
--  The ``build-${BUILD_OS}`` Override Has Been Removed: The
-   ``build-${BUILD_OS}``, which is typically ``build-linux``, override
-   has been removed because building on a host operating system other
-   than a recent version of Linux is neither supported nor recommended.
-   Dropping the override avoids giving the impression that other host
-   operating systems might be supported.
-
--  The "_remove" operator now preserves whitespace. Consequently, when
-   specifying list items to remove, be aware that leading and trailing
-   whitespace resulting from the removal is retained.
-
-   See the ":ref:`bitbake:bitbake-user-manual/bitbake-user-manual-metadata:removal (override style syntax)`"
-   section in the BitBake User Manual for a detailed example.
-
-.. _migration-2.6-systemd-configuration-now-split-out-to-system-conf:
-
-``systemd`` Configuration is Now Split Into ``systemd-conf``
-------------------------------------------------------------
-
-The configuration for the ``systemd`` recipe has been moved into a
-``system-conf`` recipe. Moving this configuration to a separate recipe
-avoids the ``systemd`` recipe from becoming machine-specific for cases
-where machine-specific configurations need to be applied (e.g. for
-``qemu*`` machines).
-
-Currently, the new recipe packages the following files::
-
-   ${sysconfdir}/machine-id
-   ${sysconfdir}/systemd/coredump.conf
-   ${sysconfdir}/systemd/journald.conf
-   ${sysconfdir}/systemd/logind.conf
-   ${sysconfdir}/systemd/system.conf
-   ${sysconfdir}/systemd/user.conf
-
-If you previously used bbappend files to append the ``systemd`` recipe to
-change any of the listed files, you must do so for the ``systemd-conf``
-recipe instead.
-
-.. _migration-2.6-automatic-testing-changes:
-
-Automatic Testing Changes
--------------------------
-
-This section provides information about automatic testing changes:
-
--  ``TEST_IMAGE`` Variable Removed: Prior to this release, you set the
-   ``TEST_IMAGE`` variable to "1" to enable automatic testing for
-   successfully built images. The ``TEST_IMAGE`` variable no longer
-   exists and has been replaced by the
-   :term:`TESTIMAGE_AUTO` variable.
-
--  Inheriting the ``testimage`` and ``testsdk`` Classes: Best
-   practices now dictate that you use the
-   :term:`IMAGE_CLASSES` variable rather than the
-   :term:`INHERIT` variable when you inherit the
-   :ref:`testimage <ref-classes-testimage*>` and
-   :ref:`testsdk <ref-classes-testsdk>` classes used for automatic
-   testing.
-
-.. _migration-2.6-openssl-changes:
-
-OpenSSL Changes
----------------
-
-`OpenSSL <https://www.openssl.org/>`__ has been upgraded from 1.0 to
-1.1. By default, this upgrade could cause problems for recipes that have
-both versions in their dependency chains. The problem is that both
-versions cannot be installed together at build time.
-
-.. note::
-
-   It is possible to have both versions of the library at runtime.
-
-.. _migration-2.6-bitbake-changes:
-
-BitBake Changes
----------------
-
-The server logfile ``bitbake-cookerdaemon.log`` is now always placed in
-the :term:`Build Directory` instead of the current
-directory.
-
-.. _migration-2.6-security-changes:
-
-Security Changes
-----------------
-
-The Poky distribution now uses security compiler flags by default.
-Inclusion of these flags could cause new failures due to stricter
-checking for various potential security issues in code.
-
-.. _migration-2.6-post-installation-changes:
-
-Post Installation Changes
--------------------------
-
-You must explicitly mark post installs to defer to the target. If you
-want to explicitly defer a postinstall to first boot on the target
-rather than at rootfs creation time, use ``pkg_postinst_ontarget()`` or
-call ``postinst_intercept delay_to_first_boot`` from ``pkg_postinst()``.
-Any failure of a ``pkg_postinst()`` script (including exit 1) triggers
-an error during the :ref:`ref-tasks-rootfs` task.
-
-For more information on post-installation behavior, see the
-":ref:`dev-manual/common-tasks:post-installation scripts`"
-section in the Yocto Project Development Tasks Manual.
-
-.. _migration-2.6-python-3-profile-guided-optimizations:
-
-Python 3 Profile-Guided Optimization
-------------------------------------
-
-The ``python3`` recipe now enables profile-guided optimization. Using
-this optimization requires a little extra build time in exchange for
-improved performance on the target at runtime. Additionally, the
-optimization is only enabled if the current
-:term:`MACHINE` has support for user-mode emulation in
-QEMU (i.e. "qemu-usermode" is in
-:term:`MACHINE_FEATURES`, which it is by
-default).
-
-If you wish to disable Python profile-guided optimization regardless of
-the value of ``MACHINE_FEATURES``, then ensure that
-:term:`PACKAGECONFIG` for the ``python3`` recipe
-does not contain "pgo". You could accomplish the latter using the
-following at the configuration level::
-
-   PACKAGECONFIG_remove_pn-python3 = "pgo"
-
-Alternatively, you can set ``PACKAGECONFIG`` using an append file
-for the ``python3`` recipe.
-
-.. _migration-2.6-miscellaneous-changes:
-
-Miscellaneous Changes
----------------------
-
-The following miscellaneous changes occurred:
-
--  Default to using the Thumb-2 instruction set for armv7a and above. If
-   you have any custom recipes that build software that needs to be
-   built with the ARM instruction set, change the recipe to set the
-   instruction set as follows::
-
-      ARM_INSTRUCTION_SET = "arm"
-
--  ``run-postinsts`` no longer uses ``/etc/*-postinsts`` for
-   ``dpkg/opkg`` in favor of built-in postinst support. RPM behavior
-   remains unchanged.
-
--  The ``NOISO`` and ``NOHDD`` variables are no longer used. You now
-   control building ``*.iso`` and ``*.hddimg`` image types directly by
-   using the :term:`IMAGE_FSTYPES` variable.
-
--  The ``scripts/contrib/mkefidisk.sh`` has been removed in favor of
-   Wic.
-
--  ``kernel-modules`` has been removed from
-   :term:`RRECOMMENDS` for ``qemumips`` and
-   ``qemumips64`` machines. Removal also impacts the ``x86-base.inc``
-   file.
-
-   .. note::
-
-      ``genericx86`` and ``genericx86-64`` retain ``kernel-modules`` as part of
-      the ``RRECOMMENDS`` variable setting.
-
--  The ``LGPLv2_WHITELIST_GPL-3.0`` variable has been removed. If you
-   are setting this variable in your configuration, set or append it to
-   the ``WHITELIST_GPL-3.0`` variable instead.
-
--  ``${ASNEEDED}`` is now included in the
-   :term:`TARGET_LDFLAGS` variable directly. The
-   remaining definitions from ``meta/conf/distro/include/as-needed.inc``
-   have been moved to corresponding recipes.
-
--  Support for DSA host keys has been dropped from the OpenSSH recipes.
-   If you are still using DSA keys, you must switch over to a more
-   secure algorithm as recommended by OpenSSH upstream.
-
--  The ``dhcp`` recipe now uses the ``dhcpd6.conf`` configuration file
-   in ``dhcpd6.service`` for IPv6 DHCP rather than re-using
-   ``dhcpd.conf``, which is now reserved for IPv4.
-
-
