From 93e4b86b3e74e19c95b762cfeb42baa0a94f212f Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Mon, 28 Oct 2024 11:13:57 -0300 Subject: 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 Cc: Catalin Marinas Cc: Ian Rogers Cc: Jiri Olsa Cc: Kan Liang Cc: Mark Rutland Cc: Namhyung Kim Link: https://lore.kernel.org/lkml/Zx-dffKdGsgkhG96@x1 Signed-off-by: Arnaldo Carvalho de Melo --- tools/arch/arm64/include/asm/cputype.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'tools') diff --git a/tools/arch/arm64/include/asm/cputype.h b/tools/arch/arm64/include/asm/cputype.h index 5a7dfeb8e8eb..488f8e751349 100644 --- a/tools/arch/arm64/include/asm/cputype.h +++ b/tools/arch/arm64/include/asm/cputype.h @@ -94,6 +94,7 @@ #define ARM_CPU_PART_NEOVERSE_V3 0xD84 #define ARM_CPU_PART_CORTEX_X925 0xD85 #define ARM_CPU_PART_CORTEX_A725 0xD87 +#define ARM_CPU_PART_NEOVERSE_N3 0xD8E #define APM_CPU_PART_XGENE 0x000 #define APM_CPU_VAR_POTENZA 0x00 @@ -176,6 +177,7 @@ #define MIDR_NEOVERSE_V3 MIDR_CPU_MODEL(ARM_CPU_IMP_ARM, ARM_CPU_PART_NEOVERSE_V3) #define MIDR_CORTEX_X925 MIDR_CPU_MODEL(ARM_CPU_IMP_ARM, ARM_CPU_PART_CORTEX_X925) #define MIDR_CORTEX_A725 MIDR_CPU_MODEL(ARM_CPU_IMP_ARM, ARM_CPU_PART_CORTEX_A725) +#define MIDR_NEOVERSE_N3 MIDR_CPU_MODEL(ARM_CPU_IMP_ARM, ARM_CPU_PART_NEOVERSE_N3) #define MIDR_THUNDERX MIDR_CPU_MODEL(ARM_CPU_IMP_CAVIUM, CAVIUM_CPU_PART_THUNDERX) #define MIDR_THUNDERX_81XX MIDR_CPU_MODEL(ARM_CPU_IMP_CAVIUM, CAVIUM_CPU_PART_THUNDERX_81XX) #define MIDR_THUNDERX_83XX MIDR_CPU_MODEL(ARM_CPU_IMP_CAVIUM, CAVIUM_CPU_PART_THUNDERX_83XX) -- cgit
