Merge tag 'perf-tools-for-v6.13-2024-11-24' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools
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 report:
- Fix --branch-history option to display more branch-related information like prediction, abort and cycles which is available on Intel machines.
$ perf record -bg -- perf test -w brstack
$ perf report --branch-history ... # # Overhead Source:Line Symbol Shared Object Predicted Abort Cycles IPC [IPC Coverage] # ........ ........................ .............. .................... ......... ..... ...... .................... # 8.17% copy_page_64.S:19 [k] copy_page [kernel.kallsyms] 50.0% 0 5 - - | ---xas_load xarray.h:171 | |--5.68%--xas_load xarray.c:245 (cycles:1) | xas_load xarray.c:242 | xas_load xarray.h:1260 (cycles:1) | xas_descend xarray.c:146 | xas_load xarray.c:244 (cycles:2) | xas_load xarray.c:245 | xas_descend xarray.c:218 (cycles:10) ...
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':
60.00 'C temp_cpu 0 rpm fan1
0.000745382 seconds time elapsed
0.000883000 seconds user 0.000000000 seconds sys
- 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".
# perf stat -a -M TopdownL1 -j true {"counter-value" : "18693525.000000", "unit" : "", "event" : "TOPDOWN.SLOTS", "event-runtime" : 5552708, "pcnt-running" : 100.00, "metric-value" : "43.226002", "metric-unit" : "% tma_backend_bound", "metric-threshold" : "bad"} {"metric-value" : "29.212267", "metric-unit" : "% tma_frontend_bound", "metric-threshold" : "bad"} {"metric-value" : "7.138972", "metric-unit" : "% tma_bad_speculation", "metric-threshold" : "good"} {"metric-value" : "20.422759", "metric-unit" : "% tma_retiring", "metric-threshold" : "good"} {"counter-value" : "3817732.000000", "unit" : "", "event" : "topdown-retiring", "event-runtime" : 5552708, "pcnt-running" : 100.00, } {"counter-value" : "5472824.000000", "unit" : "", "event" : "topdown-fe-bound", "event-runtime" : 5552708, "pcnt-running" : 100.00, } {"counter-value" : "7984780.000000", "unit" : "", "event" : "topdown-be-bound", "event-runtime" : 5552708, "pcnt-running" : 100.00, } {"counter-value" : "1418181.000000", "unit" : "", "event" : "topdown-bad-spec", "event-runtime" : 5552708, "pcnt-running" : 100.00, } ...

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"
