Merge tag 'perf-tools-for-v7.1-2026-04-17' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-toolsPull perf tools updates from Namhyung Kim: "perf report: - Add 'comm_nodigit' sort key to combine similar threads that only have different numbers in the comm. In the following example, the 'comm_nodigit' will have samples from all threads starting with "bpfrb/" into an entry "bpfrb/". $ perf report -s comm_nodigit,comm -H ... # # Overhead CommandNoDigit / Command # ........... ........................ # 20.30% swapper 20.30% swapper 13.37% chrome 13.37% chrome 10.07% bpfrb/ 7.47% bpfrb/0 0.70% bpfrb/1 0.47% bpfrb/3 0.46% bpfrb/2 0.25% bpfrb/4 0.23% bpfrb/5 0.20% bpfrb/6 0.14% bpfrb/10 0.07% bpfrb/7 - Support flat layout for symfs. The --symfs option is to specify the location of debugging symbol files. The default 'hierarchy' layout would search the symbol file using the same path of the original file under the symfs root. The new 'flat' layout would search only in the root directory. - Update 'simd' sort key for ARM SIMD flags to cover ASE/SME and more predicate flags. perf stat: - Add --pmu-filter option to select specific PMUs. This would be useful when you measure metrics from multiple instance of uncore PMUs with similar names. # perf stat -M cpa_p0_avg_bw Performance counter stats for 'system wide': 19,417,779,115 hisi_sicl0_cpa0/cpa_cycles/ # 0.00 cpa_p0_avg_bw 0 hisi_sicl0_cpa0/cpa_p0_wr_dat/ 0 hisi_sicl0_cpa0/cpa_p0_rd_dat_64b/ 0 hisi_sicl0_cpa0/cpa_p0_rd_dat_32b/ 19,417,751,103 hisi_sicl10_cpa0/cpa_cycles/ # 0.00 cpa_p0_avg_bw 0 hisi_sicl10_cpa0/cpa_p0_wr_dat/ 0 hisi_sicl10_cpa0/cpa_p0_rd_dat_64b/ 0 hisi_sicl10_cpa0/cpa_p0_rd_dat_32b/ 19,417,730,679 hisi_sicl2_cpa0/cpa_cycles/ # 0.31 cpa_p0_avg_bw 75,635,749 hisi_sicl2_cpa0/cpa_p0_wr_dat/ 18,520,640 hisi_sicl2_cpa0/cpa_p0_rd_dat_64b/ 0 hisi_sicl2_cpa0/cpa_p0_rd_dat_32b/ 19,417,674,227 hisi_sicl8_cpa0/cpa_cycles/ # 0.00 cpa_p0_avg_bw 0 hisi_sicl8_cpa0/cpa_p0_wr_dat/ 0 hisi_sicl8_cpa0/cpa_p0_rd_dat_64b/ 0 hisi_sicl8_cpa0/cpa_p0_rd_dat_32b/ 19.417734480 seconds time elapsed With --pmu-filter, users can select only hisi_sicl2_cpa0 PMU. # perf stat --pmu-filter hisi_sicl2_cpa0 -M cpa_p0_avg_bw Performance counter stats for 'system wide': 6,234,093,559 cpa_cycles # 0.60 cpa_p0_avg_bw 50,548,465 cpa_p0_wr_dat 7,552,182 cpa_p0_rd_dat_64b 0 cpa_p0_rd_dat_32b 6.234139320 seconds time elapsed Data type profiling: - Quality improvements by tracking register state more precisely - Ensure array members to get the type - Handle more cases for global variables Vendor event/metric updates: - Update various Intel events and metrics - Add NVIDIA Tegra 410 Olympus events Internal changes: - Verify perf.data header for maliciously crafted files - Update perf test to cover more usages and make them robust - Move a couple of copied kernel headers not to annoy objtool build - Fix a bug in map sorting in name order - Remove some unused codes Misc: - Fix module symbol resolution with non-zero text address - Add -t/--threads option to `perf bench mem mmap` - Track duration of exit*() syscall by `perf trace -s` - Add core.addr2line-timeout and core.addr2line-disable-warn config items"* tag 'perf-tools-for-v7.1-2026-04-17' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools: (131 commits) perf loongarch: Fix build failure with CONFIG_LIBDW_DWARF_UNWIND perf annotate: Use jump__delete when freeing LoongArch jumps perf test: Fixes for check branch stack sampling perf test: Fix inet_pton probe failure and unroll call graph perf build: fix "argument list too long" in second location perf header: Add sanity checks to HEADER_BPF_BTF processing perf header: Sanity check HEADER_BPF_PROG_INFO perf header: Sanity check HEADER_PMU_CAPS perf header: Sanity check HEADER_HYBRID_TOPOLOGY perf header: Sanity check HEADER_CACHE perf header: Sanity check HEADER_GROUP_DESC perf header: Sanity check HEADER_PMU_MAPPINGS perf header: Sanity check HEADER_MEM_TOPOLOGY perf header: Sanity check HEADER_NUMA_TOPOLOGY perf header: Sanity check HEADER_CPU_TOPOLOGY perf header: Sanity check HEADER_NRCPUS and HEADER_CPU_DOMAIN_INFO perf header: Bump up the max number of command line args allowed perf header: Validate nr_domains when reading HEADER_CPU_DOMAIN_INFO perf sample: Fix documentation typo perf arm_spe: Improve SIMD flags setting ...

Fri, 10 Apr 2026 00:14:17 +0200

perf build: fix "argument list too long" in second locationTurns out that displaying "RM $^" via quiet_cmd_rm can also upset theshell and cause it to display "argument list too long".Trying to quote $^ doesn't help.In the end, *not* displaying the (potentially long) list of files isprobably the right thing to do for a "quiet" message, anyway. Instead,let's display a count of how many files were removed. There is alwaysV=1 if more detail is required. TEST linux/tools/perf/pmu-events/metric_test.log RM ...634 orphan file(s)... LD linux/tools/perf/util/perf-util-in.oAlso move the comment regarding xargs before the rule, so it doesn'tshow up in the build output.Signed-off-by: Markus Mayer Reviewed-by: James Clark Signed-off-by: Namhyung Kim List of files: /linux/tools/perf/pmu-events/Build

regulator: fp9931: Make vin-supply mandatoryRobby Cai says:The FP9931 regulator requires a valid "vin" supply to operate correctly.Therefore, the driver should treat "vin" as a mandatory supply.This patchset updates the binding documentation to mark vin-supply as arequired property, and modifies the driver accordingly. As suggested inthe reviews from Andreas and Mark, v2 switches to usingdevm_regulator_get() since the supply is mandatory. List of files: /linux/tools/perf/pmu-events/Build
