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].

kernel-arch: drop CCACHE from KERNEL_STRIP definition

2023-11-24T15:01:37+00:00

Building linux-yocto with ccache enabled results in the 'command not found' error, because kernel-yocto.bbclass passes the KERNEL_STRIP as a single value, whic is then interpreted as a command name.

kernel: make LOCALVERSION consistent between recipes

2023-07-25T14:27:33+00:00

The initial fix for localversion setting in 6.3+ broke older recipes and also broke recipes setting localversion in a kernel recipe, as make-mod-scripts (and other locations) can trigger a regeneration of files and don't have access to the variable. Moving the setting of this variable to the global namespace doesn't make sense, so we follow the example of the kernel-abiversion and save a kernel-localversion to the build artifacts. Recipes that may regenerate scripts/dynamic files, must depend on the do_shared_workedir of the kernel and use the helper function to read the file storing the localversion.

kernel: fix localversion in v6.3+

2023-07-12T15:50:45+00:00

During testing of the v6.4 reference kernel, it was noticed that on-target modules no longer matched the magic value of the running kernel. This was due to a different localversion in the cross built kernel and the scripts / resources created on target. This was due to changes in the setlocalversion script introduced in the v6.3 series. The .scmversion file is no longer used (or packaged) to inhibit the addition of a "+" (through querying of the git status of the kernel) or the setting of a local version. We recently introduced the KERNEL_LOCALVERSION variable to allow recipes to place a value in .scmversion, so we extend the use of that variable to kernel-arch.bbclass and use it to set the exported variable LOCALVERSION. We must do it at the kernel-arch level, as the variable must be exported in any kernel build to ensure that setlocalversion always correctly sets the localversion.

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

classes: make TOOLCHAIN more permissive for kernel

2022-12-05T22:28:13+00:00

Currently TOOLCHAIN is strictly set to gcc in kernel-arch.bbclass. And this prevents any TOOLCHAIN changes for any kernel recipe. This change makes TOOLCHAIN configurable as usual.

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
