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 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".

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"
