kernel-yocto: improve metadata patching

2023-11-09T16:57:26+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.

kernel: Commit without running hooks

2023-10-30T08:50:46+00:00

The hooks are pulled from the impure environment and are often broken in our environments. There is no reason to add extra metadata or verify the commit message as its arbitrary to turn the tarball into a git repo.

kernel: Add kernel specific STRIP variable

strip can be coming from binutils or from llvm in some cases llvm-strip can fail on kernel Subprocess output:aarch64-yoe-linux-llvm-strip: error: Link field value 28 in section .rela.dyn is not a symbol table This helps in selecting which strip is used when building kernel (From OE-Core rev: 03973c8c1c93ddb1c8e05b773bfcc45aed73a99f) Signed-off-by: Khem Raj Cc: Bruce Ashfield Signed-off-by: Richard Purdie

kernel: Add kernel specific OBJDUMP

2023-03-01T21:29:31+00:00

This helps in switching toolchains cleanly for kernel build between gcc and clang Currently, some kernels allow building with clang but not all the distro might use clang as default system compiler but kernel may demand gcc which is provided via KERNEL_* variables, however kernel does use OBJCOPY at places during build and it maybe set to use llvm objcopy when using clang. That should be a deliberate setting when clang is used for kernel as well, otherwise it should use binutils provided objcopy (From OE-Core rev: 17b409f2fd97894e0943d13c2cb0d52abde647e3) Signed-off-by: Khem Raj Cc: Bruce Ashfield Signed-off-by: Alexandre Belloni Signed-off-by: Richard Purdie

kernel-yocto: improve fatal error messages of symbol_why.py

classes: Update classes to match new bitbake class scope functionality

2022-08-12T14:27:17+00:00

Move classes to classes-global or classes-recipe as appropriate to take advantage of new bitbake functionality to check class scope/usage. (From OE-Core rev: f5c128008365e141082c129417eb72d2751e8045) Signed-off-by: Richard Purdie
