tools headers arm64: Sync arm64's cputype.h with the kernel sources To get the changes in: 924725707d80bc25 ("arm64: cputype: Add Neoverse-N3 definitions") That makes this perf source code to be rebuilt: CC /tmp/build/perf-tools/util/arm-spe.o The changes in the above patch add MIDR_NEOVERSE_N3, that probably need changes in arm-spe.c, so probably we need to add it to that array? Or maybe we need to leave this for later when this is all tested on those machines? static const struct midr_range neoverse_spe[] = { MIDR_ALL_VERSIONS(MIDR_NEOVERSE_N1), MIDR_ALL_VERSIONS(MIDR_NEOVERSE_N2), MIDR_ALL_VERSIONS(MIDR_NEOVERSE_V1), {}, }; Mark Rutland recommended about arm-spe.c in a previous update to this file: "I would not touch this for now -- someone would have to go audit the TRMs to check that those other cores have the same encoding, and I think it'd be better to do that as a follow-up." That addresses this perf build warning: Warning: Kernel ABI header differences: diff -u tools/arch/arm64/include/asm/cputype.h arch/arm64/include/asm/cputype.h Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Catalin Marinas <catalin.marinas@arm.com> Cc: Ian Rogers <irogers@google.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Kan Liang <kan.liang@linux.intel.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Namhyung Kim <namhyung@kernel.org> Link: https://lore.kernel.org/lkml/Zx-dffKdGsgkhG96@x1 Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> | 1 年前 | |
perf build: Ensure sysreg-defs Makefile respects output dir Currently the sysreg-defs are written out to the source tree unconditionally, ignoring the specified output directory. Correct the build rule to emit the header to the output directory. Opportunistically reorganize the rules to avoid interleaving with the set of beauty make rules.
