linux: inherit pkgconfig in kernel.bbclass

2023-03-20T17:20:44+00:00

pkgconfig is being required to find dependencies for building kernel native tools, move "inherit pkgconfig" to kernel.bbclass so BSP kernel recipes can also benefit from it.

kernel/linux-kernel-base: Fix kernel build artefact determinism issues

2023-02-15T21:46:56+00:00

With the 6.1 kernel we've seen reproducibility/determinism issues where the kernel seems to rebuild headers referencing the hostname or local user. kernel-devsrc building after the kernel seemed to trigger it in some cases. Moving the definitions to the bbclass used by all the kernel recipe code including kernel-devsrc seems to be the best way to ensure this doesn't happen.

kernel.bbclass: remove empty module directories to prevent QA issues

2023-01-06T17:33:23+00:00

Currently, allyesconfig test runs for x86_64 fail with: ERROR: linux-yocto-5.19.17+gitAUTOINC+0cba9aa404_aaf4490d18-r0 do_package: QA Issue: linux-yocto: Files/directories were installed but not shipped in any package: /lib/modules/5.19.17/kernel/drivers/nvdimm With CONFIG_NVDIMM_TEST_BUILD=m, an empty nvdimm directory is created during modules_install, which triggers the QA issue. Extend kernel_do_install() to also remove inner empty directories that might get created by modules_install.

kernel.bbclass: make KERNEL_DEBUG_TIMESTAMPS work at rebuild

2022-12-07T15:02:45+00:00

Currently, the KERNEL_DEBUG_TIMESTAMPS is not working as expected at rebuild. That is, even if we set it to "1", the kernel build time is not changed. The problem could be reproduced by the following steps. 1. bitbake core-image-minimal; start image and check `uname -a` output. 2. set in local.conf: KERNEL_DEBUG_TIMESTAMPS = "1" 3. bitbake core-image-minimal; start image and check `uname -a` output. It's expected that after enabling KERNEL_DEBUG_TIMESTAMPS, the kernel build time will be set to current date. But it's not. This is because the compile.h was not re-generated when do_compile task was re-executed. In mkcompile_h, we have: """ # Only replace the real compile.h if the new one is different, # in order to preserve the timestamp and avoid unnecessary # recompilations. # We don't consider the file changed if only the date/time changed, # unless KBUILD_BUILD_TIMESTAMP was explicitly set (e.g. for # reproducible builds with that value referring to a commit timestamp). # A kernel config change will increase the generation number, thus # causing compile.h to be updated (including date/time) due to the # changed comment in the # first line. """ It has made it very clear that it will not be re-generated unless we have KBUILD_BUILD_TIMESTAMP set explicitly. So we set this variable explicitly in do_compile to fix this issue.

kernel.bbclass: Include randstruct seed assets in STAGING_KERNEL_BUILDDIR

2022-11-24T15:30:01+00:00

When building with CONFIG_MODVERSIONS=y and CONFIG_RANDSTRUCT=y we need to copy the build assets generated for the randstrutc seed to STAGING_KERNEL_BUILDDIR, otherwise the out-of-tree modules build will generate those assets which will result in a different RANDSTRUCT_HASHED_SEED.

kernel: Clear SYSROOT_DIRS instead of replacing sysroot_stage_all

2022-11-10T14:39:24+00:00

Replacing sysroot_stage_all by a no-op recipe makes it difficult for bbappends to stage files intentionally. Instead, just clear SYSROOT_DIRS, allowing other bbappends to easily add new directories.

kernel: Use consistent make flags for menuconfig

2022-09-16T16:53:22+00:00

We're currently only passing in a subset of the kernel make flags to menuconfig. Fix this to be consistent with all the other kernel operations since these are becomming increasingly reliant on host compilers and flags and target toolchains as well.

kernel: Always set CC and LD for the kernel build

2022-09-16T16:53:22+00:00

It as been bothering me a bit that we don't set CC and LD consistently for the kernel make calls and this can lead to interesting bugs as the kernel increases in complexity. Add them to EXTRA_OEMAKE so they're always passed in. This makes everything slightly more consistent and less likely to break in future.
