Merge tag 'perf-tools-for-v6.16-1-2025-06-03' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools
Pull perf tools updates from Arnaldo Carvalho de Melo: "perf report/top/annotate TUI:
- Accept the left arrow key as a Zoom out if done on the first column
- Show if source code toggle status in title, to help spotting bugs with the various disassemblers (capstone, llvm, objdump)
- Provide feedback on unhandled hotkeys
Build:
- Better inform when certain features are not available with warnings in the build process and in 'perf version --build-options' or 'perf -vv'
perf record:
- Improve the --off-cpu code by synthesizing events for switch-out -> switch-in intervals using a BPF program. This can be fine tuned using a --off-cpu-thresh knob
perf report:
- Add 'tgid' sort key
perf mem/c2c:
- Add 'op', 'cache', 'snoop', 'dtlb' output fields
- Add support for 'ldlat' on AMD IBS (Instruction Based Sampling)
perf ftrace:
- Use process/session specific trace settings instead of messing with the global ftrace knobs
perf trace:
- Implement syscall summary in BPF
- Support --summary-mode=cgroup
- Always print return value for syscalls returning a pid
- The rseq and set_robust_list don't return a pid, just -errno
perf lock contention:
- Symbolize zone->lock using BTF
- Add -J/--inject-delay option to estimate impact on application performance by optimization of kernel locking behavior
perf stat:
- Improve hybrid support for the NMI watchdog warning
Symbol resolution:
- Handle 'u' and 'l' symbols in /proc/kallsyms, resolving some Rust symbols
- Improve Rust demangler
Hardware tracing:
Intel PT:
- Fix PEBS-via-PT data_src
- Do not default to recording all switch events
- Fix pattern matching with python3 on the SQL viewer script
arm64:
- Fixups for the hip08 hha PMU
Vendor events:
- Update Intel events/metrics files for alderlake, alderlaken, arrowlake, bonnell, broadwell, broadwellde, broadwellx, cascadelakex, clearwaterforest, elkhartlake, emeraldrapids, grandridge, graniterapids, haswell, haswellx, icelake, icelakex, ivybridge, ivytown, jaketown, lunarlake, meteorlake, nehalemep, nehalemex, rocketlake, sandybridge, sapphirerapids, sierraforest, skylake, skylakex, snowridgex, tigerlake, westmereep-dp, westmereep-sp, westmereep-sx
python support:
- Add support for event counts in the python binding, add a counting.py example
perf list:
- Display the PMU name associated with a perf metric in JSON
perf test:
- Hybrid improvements for metric value validation test
- Fix LBR test by ignoring idle task
- Add AMD IBS sw filter ana d'ldlat' tests
- Add 'perf trace --summary-mode=cgroup' test
- Add tests for the various language symbol demanglers
Miscellaneous:
- Allow specifying the cpu an event will be tied using '-e event/cpu=N/'
- Sync various headers with the kernel sources
- Add annotations to use clang's -Wthread-safety and fix some problems it detected
- Make dump_stack() use perf's symbol resolution to provide better backtraces
- Intel TPEBS support cleanups and fixes. TPEBS stands for Timed PEBS (Precision Event-Based Sampling), that adds timing info, the retirement latency of instructions
- Various memory allocation (some detected by ASAN) and reference counting fixes
- Add a 8-byte aligned PERF_RECORD_COMPRESSED2 to replace PERF_RECORD_COMPRESSED
- Skip unsupported event types in perf.data files, don't stop when finding one
- Improve lookups using hashmaps and binary searches"

perf intel-pt: Do not default to recording all switch events
On systems with many CPUs, recording extra context switch events can be excessive and unnecessary. Add perf config intel-pt.all-switch-events=false to control the behaviour.
Example:

Pull perf tools updates from Namhyung Kim: "perf record:
- Enable leader sampling for inherited task events. It was supported only for system-wide events but the kernel started to support such a setup since v6.12.
This is to reduce the number of PMU interrupts. The samples of the leader event will contain counts of other events and no samples will be generated for the other member events.
$ perf record -e '{cycles,instructions}:S' ${MYPROG}

perf stat:
- Add HWMON PMU support.
The HWMON provides various system information like CPU/GPU temperature, fan speed and so on. Expose them as PMU events so that users can see the values using perf stat commands.
$ perf stat -e temp_cpu,fan1 true
Performance counter stats for 'true':

- Display metric threshold in JSON output.
Some metrics define thresholds to classify value ranges. It used to be in a different color but it won't work for JSON.
Add "metric-threshold" field to the JSON that can be one of "good", "less good", "nearly bad" and "bad".

Build:
- Make libunwind opt-in (LIBUNWIND=1) rather than opt-out.
The perf tools are generally built with libelf and libdw which has unwinder functionality. The libunwind support predates it and no need to have duplicate unwinders by default.
- Rename NO_DWARF=1 build option to NO_LIBDW=1 in order to clarify it's using libdw for handling DWARF information.
Internals:
- Do not set exclude_guest bit in the perf_event_attr by default.
This was causing a trouble in AMD IBS PMU as it doesn't support the bit. The bit will be set when it's needed later by the fallback logic. Also update the missing feature detection logic to make sure not clear supported bits unnecessarily.
- Run perf test in parallel by default and mark flaky tests "exclusive" to run them serially at the end. Some test numbers are changed but the test can complete in less than half the time.
JSON vendor events:
- Add AMD Zen 5 events and metrics.
- Add i.MX91 and i.MX95 DDR metrics
- Fix HiSilicon HIP08 Topdown metric name.
- Support compat events on PowerPC"

perf pmu: Allow hardcoded terms to be applied to attributes
Hard coded terms like "config=10" are skipped by perf_pmu__config assuming they were already applied to a perf_event_attr by parse event's config_attr function. When doing a reverse number to name lookup in perf_pmu__name_from_config, as the hardcoded terms aren't applied the config value is incorrect leading to misses or false matches. Fix this by adding a parameter to have perf_pmu__config apply hardcoded terms too (not just in parse event's config_term_common).
