From: Daniel Gomez <da.gomez@xxxxxxxxxxx> program_invocation_short_name() may not be available in other systems. Instead, replace it with the argv[0] to pass the executable name.

Suggested-by: Masahiro Yamada <masahiroy@xxxxxxxxxx> Signed-off-by: Daniel Gomez <da.gomez@xxxxxxxxxxx> --- This last patch allows for building the Linux kernel allyesconfig target for arm64 in macOS hosts with Clang/LLVM. Summary of previous feedback and work: Other Makefile targets, such as defconfig, can already be built successfully if the necessary headers are provided and the Linux kernel build system is configured appropriately. To facilitate this process, the Bee Headers [1] project was created not only to serve as reference but also to document [2] the process and supply the missing headers. To get started: 1. Setup: diskutil apfs addVolume /dev/disk<N> "Case-sensitive APFS" linux brew install coreutils findutils gnu-sed gnu-tar grep llvm make \ pkg-config brew tap bee-headers/bee-headers brew install bee-headers/bee-headers/bee-headers 2. Build: source bee-init make LLVM=1 defconfig make LLVM=1 -j$(nproc) [1] Project: https://github.com/bee-headers [2] Documentation: https://github.com/bee-headers/homebrew-bee-headers/blob/main/README.md The changelog below has been refined to focus only on feedback related to the xe driver. Version 3 was submitted some time ago, and although some errors occurred in CI, they appear to be unrelated to the changes.
Is this the approach taken for other similar issues you had? Note that argv[0] and program_invocation_short_name are not the same thing. For this particular binary I don't really care and if it's the approach taken in other places, I'm ok using it. I was expecting you'd take the acks and merge it all through a single tree since you received push back on the need to build the kernel in macOS. Is this the only thing missing and you'd want it to go through drm? Lucas De Marchi
