Release notes for 4.3 (nandbield)
|
|
----------------------------------
|
|
|
|
New Features / Enhancements in 4.3
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
- Linux kernel 6.5 and 6.1, gcc 13, glibc 2.38 and other recipe upgrades
|
|
|
|
- New variables:
|
|
|
|
- :term:`FILE_LAYERNAME`: bitbake now sets this to the name of the layer containing the recipe
|
|
|
|
- :term:`FIT_ADDRESS_CELLS` and :term:`UBOOT_FIT_ADDRESS_CELLS`.
|
|
See details below.
|
|
|
|
- :term:`KERNEL_DTBDEST`: directory where to install DTB files.
|
|
|
|
- :term:`KERNEL_DTBVENDORED`: whether to keep vendor subdirectories.
|
|
|
|
- :term:`LICENSE_FLAGS_DETAILS`: add extra details about a recipe license
|
|
in case it is not allowed by :term:`LICENSE_FLAGS_ACCEPTED`.
|
|
|
|
- :term:`FILE_LAYERNAME`: bitbake now sets this to the name of the layer containing the recipe.
|
|
|
|
- :term:`KERNEL_LOCALVERSION`: to add a string to the kernel version information.
|
|
|
|
- :term:`OEQA_REPRODUCIBLE_TEST_PACKAGE`: to restrict package managers used in reproducibility testing.
|
|
|
|
- :term:`KERNEL_STRIP`: to specify the command to strip the kernel binary.
|
|
|
|
- Layername functionality available through overrides
|
|
|
|
Code can now know which layer a recipe is coming from through the newly added :term:`FILE_LAYERNAME`
|
|
variable. This has been added as an override of the form ``layer-<layername>``. In particular,
|
|
this means QA checks can now be layer specific, for example::
|
|
|
|
ERROR_QA:layer-core:append = " patch-status"
|
|
|
|
which will enable the ``patch-status`` QA check for the core layer.
|
|
|
|
- Architecture-specific enhancements:
|
|
|
|
- RISCV support is now enabled in LLVM 17.
|
|
|
|
- Loongarch support in the :ref:`ref-classes-linuxloader` class and
|
|
``core-image-minimal-initramfs`` image.
|
|
|
|
- Kernel-related enhancements:
|
|
|
|
- New core recipes:
|
|
|
|
- New classes:
|
|
|
|
- A ``ptest-cargo`` class was added to allow Cargo based recipes to easily add ptests
|
|
|
|
- QEMU/runqemu enhancements:
|
|
|
|
- QEMU has been upgraded to version 8.0
|
|
|
|
- Rust improvements:
|
|
|
|
- Rust has been upgraded to version 1.70
|
|
|
|
- Image-related enhancements:
|
|
|
|
- Distribution-related enhancements:
|
|
|
|
- The ``poky-altcfg`` distribution enables the ``usrmerge``
|
|
:ref:`distro feature <ref-manual/features:Distro Features>`.
|
|
|
|
- wic Image Creator enhancements:
|
|
|
|
- FIT image related improvements:
|
|
|
|
- New :term:`FIT_ADDRESS_CELLS` and :term:`UBOOT_FIT_ADDRESS_CELLS` variables allowing
|
|
to specify 64 bit addresses, typically for loading U-Boot.
|
|
|
|
- SDK-related improvements:
|
|
|
|
- Testing:
|
|
|
|
- Utility script changes:
|
|
|
|
- BitBake improvements:
|
|
|
|
- The BitBake Cooker log now contains notes when the caches are
|
|
invalidated which is useful for memory resident bitbake debugging.
|
|
|
|
- Packaging changes:
|
|
|
|
- :term:`SPDX` improvements:
|
|
|
|
- :term:`SPDX` manifests are now generated by default.
|
|
|
|
- Prominent documentation updates:
|
|
|
|
- New :doc:`../contributor-guide/index` document.
|
|
|
|
- Long due documentation for the :ref:`ref-classes-devicetree` class.
|
|
|
|
- New :ref:`summary about available init systems
|
|
<dev-manual/init-manager:summary>`.
|
|
|
|
- New documentation for the :ref:`ref-classes-uboot-sign` class and
|
|
its variables and for the :ref:`ref-classes-kernel-devicetree` class
|
|
variables.
|
|
|
|
- Miscellaneous changes:
|
|
|
|
|
|
- Git based recipes in OE-Core which used the git protocol have been
|
|
changed to use https where possibile. https is now believed to be
|
|
faster and more reliable.
|
|
|
|
- The ``os-release`` recipe added a ``CPE_NAME`` to the fields provided, with the
|
|
default being populated from :term:`DISTRO`.
|
|
|
|
- The ``psplash`` recipe now accepts a PNG format image through :term:`SPLASH_IMAGES`,
|
|
instead of a harder to generate and modify ``.h`` file.
