Merge tag 'perf-tools-for-v6.5-1-2023-06-28' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools-next
Pull perf tools updates from Namhyung Kim: "Internal cleanup:
- Refactor PMU data management to handle hybrid systems in a generic way.
Do more work in the lexer so that legacy event types parse more easily. A side-effect of this is that if a PMU is specified, scanning sysfs is avoided improving start-up time.
- Fix hybrid metrics, for example, the TopdownL1 works for both performance and efficiency cores on Intel machines. To support this, sort and regroup events after parsing.
- Add reference count checking for the 'thread' data structure.
- Lots of fixes for memory leaks in various places thanks to the ASAN and Ian's refcount checker.
- Reduce the binary size by replacing static variables with local or dynamically allocated memory.
- Introduce shared_mutex for annotate data to reduce memory footprint.
- Make filesystem access library functions more thread safe.
Test:
- Organize cpu_map tests into a single suite.
- Add metric value validation test to check if the values are within correct value ranges.
- Add perf stat stdio output test to check if event and metric names match.
- Add perf data converter JSON output test.
- Fix a lot of issues reported by shellcheck(1). This is a preparation to enable shellcheck by default.
- Make the large x86 new instructions test optional at build time using EXTRA_TESTS=1.
- Add a test for libpfm4 events.
perf script:
- Add 'dsoff' outpuf field to display offset from the DSO.
$ perf script -F comm,pid,event,ip,dsoff ls 2695501 cycles: 152cc73ef4b5 (/usr/lib/x86_64-linux-gnu/ld-2.31.so+0x1c4b5) ls 2695501 cycles: ffffffff99045b3e ([kernel.kallsyms]) ls 2695501 cycles: ffffffff9968e107 ([kernel.kallsyms]) ls 2695501 cycles: ffffffffc1f54afb ([kernel.kallsyms]) ls 2695501 cycles: ffffffff9968382f ([kernel.kallsyms]) ls 2695501 cycles: ffffffff99e00094 ([kernel.kallsyms]) ls 2695501 cycles: 152cc718a8d0 (/usr/lib/x86_64-linux-gnu/libselinux.so.1+0x68d0) ls 2695501 cycles: ffffffff992a6db0 ([kernel.kallsyms])
- Adjust width for large PID/TID values.
perf report:
- Robustify reading addr2line output for srcline by checking sentinel output before the actual data and by using timeout of 1 second.
- Allow config terms (like 'name=ABC') with breakpoint events.
$ perf record -e mem:0x55feb98dd169:x/name=breakpoint/ -p 19646 -- sleep 1
perf annotate:
- Handle x86 instruction suffix like 'l' in 'movl' generally.
- Parse instruction operands properly even with a whitespace. This is needed for llvm-objdump output.
- Support RISC-V binutils lookup using the triplet prefixes.
- Add '<' and '>' key to navigate to prev/next symbols in TUI.
- Fix instruction association and parsing for LoongArch.
perf stat:
- Add --per-cache aggregation option, optionally specify a cache level like `--per-cache=L2`.
$ sudo perf stat --per-cache -a -e ls_dmnd_fills_from_sys.ext_cache_remote --\ taskset -c 0-15,64-79,128-143,192-207\ perf bench sched messaging -p -t -l 100000 -g 8

- Allow --cputype option to have any PMU name (not just hybrid).
- Fix output value not to added when it runs multiple times with -r option.
perf list:
- Show metricgroup description from JSON file called metricgroups.json.
- Allow 'pfm' argument to list only libpfm4 events and check each event is supported before showing it.
JSON vendor events:
- Avoid event grouping using "NO_GROUP_EVENTS" constraints. The topdown events are correctly grouped even if no group exists.
- Add "Default" metric group to print it in the default output. And use "DefaultMetricgroupName" to indicate the real metric group name.
- Add AmpereOne core PMU events.
Misc:
- Define man page date correctly.
- Track exception level properly on ARM CoreSight ETM.
- Allow anonymous struct, union or enum when retrieving type names from DWARF.
- Fix incorrect filename when calling `perf inject --jit`.
- Handle PLT size correctly on LoongArch"

perf pmus: Remove perf_pmus__has_hybrid
perf_pmus__has_hybrid was used to detect when there was >1 core PMU, this can be achieved with perf_pmus__num_core_pmus that doesn't depend upon is_pmu_hybrid and PMU name comparisons. When modifying the function calls take the opportunity to improve comments, enable/simplify tests that were previously failing for hybrid but now pass and to simplify generic code.

Pull perf tool updates from Arnaldo Carvalho de Melo: "New features:
- Add 'trace' subcommand for 'perf ftrace', setting the stage for more 'perf ftrace' subcommands. Not using a subcommand yields the previous behaviour of 'perf ftrace'.
- Add 'latency' subcommand to 'perf ftrace', that can use the function graph tracer or a BPF optimized one, via the -b/--use-bpf option.
E.g.:
$ sudo perf ftrace latency -a -T mutex_lock sleep 1 # DURATION | COUNT | GRAPH | 0 - 1 us | 4596 | ######################## | 1 - 2 us | 1680 | ######### | 2 - 4 us | 1106 | ##### | 4 - 8 us | 546 | ## | 8 - 16 us | 562 | ### | 16 - 32 us | 1 | | 32 - 64 us | 0 | | 64 - 128 us | 0 | | 128 - 256 us | 0 | | 256 - 512 us | 0 | | 512 - 1024 us | 0 | | 1 - 2 ms | 0 | | 2 - 4 ms | 0 | | 4 - 8 ms | 0 | | 8 - 16 ms | 0 | | 16 - 32 ms | 0 | | 32 - 64 ms | 0 | | 64 - 128 ms | 0 | | 128 - 256 ms | 0 | | 256 - 512 ms | 0 | | 512 - 1024 ms | 0 | | 1 - ... s | 0 | |
The original implementation of this command was in the bcc tool.
- Support --cputype option for hybrid events in 'perf stat'.
Improvements:
- Call chain improvements for ARM64.
- No need to do any affinity setup when profiling pids.
- Reduce multiplexing with duration_time in 'perf stat' metrics.
- Improve error message for uncore events, stating that some event groups are can only be used in system wide (-a) mode.
- perf stat metric group leader fixes/improvements, including arch specific changes to better support Intel topdown events.
- Probe non-deprecated sysfs path first, i.e. try the path /sys/devices/system/cpu/cpuN/topology/thread_siblings first, then the old /sys/devices/system/cpu/cpuN/topology/core_cpus.
- Disable debuginfod by default in 'perf record', to avoid stalls on distros such as Fedora 35.
- Use unbuffered output in 'perf bench' when pipe/tee'ing to a file.
- Enable ignore_missing_thread in 'perf trace'
Fixes:
- Avoid TUI crash when navigating in the annotation of recursive functions.
- Fix hex dump character output in 'perf script'.
- Fix JSON indentation to 4 spaces standard in the ARM vendor event files.
- Fix use after free in metric__new().
- Fix IS_ERR_OR_NULL() usage in the perf BPF loader.
- Fix up cross-arch register support, i.e. when printing register names take into account the architecture where the perf.data file was collected.
- Fix SMT fallback with large core counts.
- Don't lower case MetricExpr when parsing JSON files so as not to lose info such as the ":G" event modifier in metrics.
perf test:
- Add basic stress test for sigtrap handling to 'perf test'.
- Fix 'perf test' failures on s/390
- Enable system wide for metricgroups test in 'perf test´.
- Use 3 digits for test numbering now we can have more tests.
Arch specific:
- Add events for Arm Neoverse N2 in the ARM JSON vendor event files
- Support PERF_MEM_LVLNUM encodings in powerpc, that came from a single patch series, where I incorrectly merged the kernel bits, that were then reverted after coordination with Michael Ellerman and Stephen Rothwell.
- Add ARM SPE total latency as PERF_SAMPLE_WEIGHT.
- Update AMD documentation, with info on raw event encoding.
- Add support for global and local variants of the "p_stage_cyc" sort key, applicable to perf.data files collected on powerpc.
- Remove duplicate and incorrect aux size checks in the ARM CoreSight ETM code.
Refactorings:
- Add a perf_cpu abstraction to disambiguate CPUs and CPU map indexes, fixing problems along the way.
- Document CPU map methods.
UAPI sync:
- Update arch/x86/lib/mem{cpy,set}_64.S copies used in 'perf bench mem memcpy'
- Sync UAPI files with the kernel sources: drm, msr-index, cpufeatures.
Build system
- Enable warnings through HOSTCFLAGS.
- Drop requirement for libstdc++.so for libopencsd check
libperf:
- Make libperf adopt perf_counts_values__scale() from tools/perf/util/.
- Add a stat multiplexing test to libperf"

perf cpumap: Give CPUs their own type
A common problem is confusing CPU map indices with the CPU, by wrapping the CPU with a struct then this is avoided. This approach is similar to atomic_t.

perf cpumap: Give CPUs their own type
A common problem is confusing CPU map indices with the CPU, by wrapping the CPU with a struct then this is avoided. This approach is similar to atomic_t.
Committer notes:
To make it build with BUILD_BPF_SKEL=1 these files needed the conversions to 'struct perf_cpu' usage:
tools/perf/util/bpf_counter.c tools/perf/util/bpf_counter_cgroup.c tools/perf/util/bpf_ftrace.c
Also perf_env__get_cpu() was removed back in "perf cpumap: Switch cpu_map__build_map to cpu function".
Additionally these needed to be fixed for the ARM builds to complete:
tools/perf/arch/arm/util/cs-etm.c tools/perf/arch/arm64/util/pmu.c
