kernel.bbclass: Set pkg-config variables for building modules

2024-03-13T13:59:26+00:00

The pkg-config workaround has been applied for kernel image building, but not for module building. So pkg-config variables are different between do_compile and do_compile_kernelmodules tasks. It may unnecessary trigger rebuilding of a few host tools at the later task. Especially when CONFIG_DEBUG_INFO_BTF is enabled in the kernel, it may even trigger rebuilding vmlinux at do_compile_kernelmodules due to the rebuilt host tools such as certs/extract-cert or objtool (on x86). This eventually creates an inconsistent set of kernel binaries. Here is the repro steps: - Check out nanbield on x86 - The unexpected rebuild happens on kirkstone or possibly earlier - Ensure that pahole is available (e.g. via meta-oe) - Set KERNEL_DEBUG to "True" to properly set up PAHOLE e.g. $ export KERNEL_DEBUG="True" $ export BB_ENV_PASSTHROUGH_ADDITIONS="${BB_ENV_PASSTHROUGH_ADDITIONS} KERNEL_DEBUG" - Enable CONFIG_DEBUG_INFO_BTF=y e.g. $ bitbake -c menuconfig virtual/kernel -> Kernel hacking -> Compile-time checks and compiler options -> Generate BTF typeinfo - Build the kernel e.g. $ bitbake virtual/kernel The BTF information in the resulting bzImage and kernel modules are inconsistent, because the module's BTF information is generated using the "second" vmlinux that doesn't have the identical BTF to the "first" vmlinux. These modules can't be loaded at runtime due to the BTF mismatch. This also leads to a build-id mismatch between the installed bzImage and vmlinux since the bzImage is created from the first vmlinux, but the installed vmlinux is the second one. $ eu-readelf -n tmp/work/qemux86_64-poky-linux/linux-yocto/6.5.13+git/image/boot/{bzImage*,vmlinux*} | grep "Build ID" Build ID: 4a0d62ee7fef0244950f0f604253729875bea493 Build ID: fb99b3d91399dbe42bf67ddee59e0f5a0c7f74d9 To avoid the unexpected rebuilding that results in such inconsistency, set the same pkg-config variables when building kernel and modules. For kernel 5.19 and above, simply set the HOSTPKG_CONFIG in the make command line.

allarch: Fix allarch corner case

2024-02-22T14:34:14+00:00

Most of the allarch code is conditional and only set if the recipe remains marked as allarch. The qemu wrapper handling is not handled in the same way however and is unconditional. Move the code to some slightly uglier inline python to allow it to be conditional and match the way the rest of the code works.

qemu.bbclass: fix a python TypeError

2024-02-07T14:00:02+00:00

QEMU_OPTIONS can be empty which will trigger a exception TypeError: | can only concatenate str (not "NoneType") to str. Fix it by setting a empty string. ALso removed two useless blanks.

testimage: Drop target_dumper and most of monitor_dumper

2024-01-04T14:09:44+00:00

The target_dumper code is basically broken. It has been reading binary files over the text base serial communication and runs at every command failure which makes no sense. Each run might overwrite files from the previous run and the output appears corrupted due to confusion from the binary data. For now, remove the commands and the target dumper code as the command and execution point are problematic. Also remove the same pieces of the monitor code but leave the command list since in theory this can be moved to a more useful place in the code.

kernel-arch: use ccache only for compiler

2024-01-04T14:09:43+00:00

Attempting to use it with other tools is not beneficial, only with the compiler. Confirmation from ccache's maintainer [1].

testimage: Exclude wtmp from target-dumper commands

2023-12-22T15:23:26+00:00

wtmp is filled with binary data which the run_serial command can't cope with. Catting this results in confusion of the serial interface and potentially large backlogs of data in the buffers which can hang qemu. Exclude the problematic files from the command.

kernel-yocto: improve metadata patching

2023-12-15T13:54:00+00:00

The ability to patch the kernel-yocto metadata was added to support debug and easier test cycles on kernel-cache provided fragments. As such, it was very simple and has limited functionality. That being said, it is an available feature and can be improved to handle patches that fail to apply. The main kernel patching is already handled by the kern-tools, so we extend the patching of the meta-data to same tools and inherit more functinality from the scripts.
