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. Fixes build error when program_invocation_short_name is not available: drivers/gpu/drm/xe/xe_gen_wa_oob.c:34:3: error: use of undeclared identifier 'program_invocation_short_name' 34 | program_invocation_short_name); | ^ 1 error generated. 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. --- Changes in v3 (RESEND): - Update cover letter and To/Cc list. - Rebase patch onto next-20250221. - Link to v3: https://lore.kernel.org/all/20240925-macos-build-support-v3-1-233dda880e60@xxxxxxxxxxx/ Changes in v3: - Update drm/xe patch to replace program_invocation_short_name with argv[0] instead of using getprogname + ifdef as suggested by Masahiro. - Link to v2: https://lore.kernel.org/r/20240906-macos-build-support-v2-0-06beff418848@xxxxxxxxxxx Changes in v2: - Adapt xe_gen_wa_oob to solve getprogname()/ program_invocation_short_name in runtime. as suggested by Lucas De Marchi. - Link to v1: https://lore.kernel.org/r/20240807-macos-build-support-v1-0-4cd1ded85694@xxxxxxxxxxx --- drivers/gpu/drm/xe/xe_gen_wa_oob.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/drivers/gpu/drm/xe/xe_gen_wa_oob.c b/drivers/gpu/drm/xe/xe_gen_wa_oob.c index 904cf47925aa1d5bc37983af83232d5e4697c49e..ed9183599e31cc9d76da3f22c9fb3884384a49bc 100644 --- a/drivers/gpu/drm/xe/xe_gen_wa_oob.c +++ b/drivers/gpu/drm/xe/xe_gen_wa_oob.c @@ -28,10 +28,10 @@ "\n" \ "#endif\n" -static void print_usage(FILE *f) +static void print_usage(FILE *f, const char *progname) { fprintf(f, "usage: %s <input-rule-file> <generated-c-source-file> <generated-c-header-file>\n", - program_invocation_short_name); + progname); } static void print_parse_error(const char *err_msg, const char *line, @@ -144,7 +144,7 @@ int main(int argc, const char *argv[]) if (argc < 3) { fprintf(stderr, "ERROR: wrong arguments\n"); - print_usage(stderr); + print_usage(stderr, argv[0]); return 1; } --- base-commit: d4b0fd87ff0d4338b259dc79b2b3c6f7e70e8afa change-id: 20250224-macos-build-support-xe-f017c84113b6 Best regards, -- Daniel Gomez <da.gomez@xxxxxxxxxxx>
