Merge tag 'perf-tools-for-v6.9-2024-03-13' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools Pull perf tools updates from Namhyung Kim: "perf stat: - Support new 'cluster' aggregation mode for shared resources depending on the hardware configuration: $ sudo perf stat -a --per-cluster -e cycles,instructions sleep 1 Performance counter stats for 'system wide': S0-D0-CLS0 2 85,051,822 cycles S0-D0-CLS0 2 73,909,908 instructions # 0.87 insn per cycle S0-D0-CLS2 2 93,365,918 cycles S0-D0-CLS2 2 83,006,158 instructions # 0.89 insn per cycle S0-D0-CLS4 2 104,157,523 cycles S0-D0-CLS4 2 53,234,396 instructions # 0.51 insn per cycle S0-D0-CLS6 2 65,891,079 cycles S0-D0-CLS6 2 41,478,273 instructions # 0.63 insn per cycle 1.002407989 seconds time elapsed - Various fixes and cleanups for event metrics including NaN handling perf script: - Use libcapstone if available to disassemble the instructions. This enables 'perf script -F disasm' and 'perf script --insn-trace=disasm' (for Intel-PT): $ perf script -F event,ip,disasm cycles:P: ffffffffa988d428 wrmsr cycles:P: ffffffffa9839d25 movq %rax, %r14 cycles:P: ffffffffa9cdcaf0 endbr64 cycles:P: ffffffffa988d428 wrmsr cycles:P: ffffffffa988d428 wrmsr cycles:P: ffffffffaa401f86 iretq cycles:P: ffffffffa99c4de5 movq 0x30(%rcx), %r8 cycles:P: ffffffffa988d428 wrmsr cycles:P: ffffffffaa401f86 iretq cycles:P: ffffffffa9907983 movl 0x68(%rbx), %eax cycles:P: ffffffffa988d428 wrmsr - Expose sample ID / stream ID to python scripts perf test: - Add more perf test cases from Redhat internal test suites. This time it adds the base infra and a few perf probe tests. More to come. :) - Add 'perf test -p' for parallel execution and fix some issues found by the parallel test - Support symbol test to print symbols in given (active) module: $ perf test -F -v Symbols --dso /lib/modules/$(uname -r)/kernel/fs/ext4/ext4.ko --- start --- Testing /lib/modules/6.5.13-1rodete2-amd64/kernel/fs/ext4/ext4.ko Overlapping symbols: 7a990-7a9a0 l __pfx_ext4_exit_fs 7a990-7a9a0 g __pfx_cleanup_module Overlapping symbols: 7a9a0-7aa1c l ext4_exit_fs 7a9a0-7aa1c g cleanup_module ... JSON metric updates: - A new round of Intel metric updates - Support Power11 PVR (compatible to Power10) - Fix cache latency events on Zen 4 to set SliceId properly Internal: - Fix reference counting for 'map' data structure, tireless work from Ian! - More memory optimization for struct thread and annotate histogram. Now, 'perf report' (TUI) and 'perf annotate' should be much lighter-weight in terms of memory footprint - Support cross-arch perf register access. Clean up the build configuration so that it can detect arch-register support at runtime. This can allow to parse register data in sample which was recorded in a different arch Others: - Sync task state in 'perf sched' to kernel using trace event fields. The task states have been changed so tools cannot assume a fixed encoding - Clean up 'perf mem' to generalize the arch-specific events - Add support for local and global variables to data type profiling. This would increase the success rate of type resolution with DWARF - Add short option -H for --hierarchy in 'perf report' and 'perf top'" * tag 'perf-tools-for-v6.9-2024-03-13' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools: (154 commits) perf annotate: Add comments in the data structures perf annotate: Remove sym_hist.addr[] array perf annotate: Calculate instruction overhead using hashmap perf annotate: Add a hashmap for symbol histogram perf threads: Reduce table size from 256 to 8 perf threads: Switch from rbtree to hashmap perf threads: Move threads to its own files perf machine: Move machine's threads into its own abstraction perf machine: Move fprintf to for_each loop and a callback perf trace: Ignore thread hashing in summary perf report: Sort child tasks by tid perf vendor events amd: Fix Zen 4 cache latency events perf version: Display availability of OpenCSD support perf vendor events intel: Add umasks/occ_sel to PCU events. perf map: Fix map reference count issues libperf evlist: Avoid out-of-bounds access perf lock contention: Account contending locks too perf metrics: Fix segv for metrics with no events perf metrics: Fix metric matching perf pmu: Fix a potential memory leak in perf_pmu__lookup() ...
