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

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 sched:

- Add -P/--pre-migrations option for 'timehist' sub-command to track
time a task waited on a run-queue before migrating to a different
CPU.

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"

 SYNOPSIS
 --------
 [verse]
-'perf list' [--no-desc] [--long-desc]
+'perf list' [<options>]
             [hw|sw|cache|tracepoint|pmu|sdt|metric|metricgroup|event_glob]
 
 DESCRIPTION
···
 For accessing trace point events perf needs to have read access to
 /sys/kernel/tracing, even when perf_event_paranoid is in a relaxed
 setting.
+
+TOOL/HWMON EVENTS
+-----------------
+
+Some events don't have an associated PMU instead reading values
+available to software without perf_event_open. As these events don't
+support sampling they can only really be read by tools like perf stat.
+
+Tool events provide times and certain system parameters. Examples
+include duration_time, user_time, system_time and num_cpus_online.
+
+Hwmon events provide easy access to hwmon sysfs data typically in
+/sys/class/hwmon. This information includes temperatures, fan speeds
+and energy usage.
+
 
 TRACING
 -------

tools/perf/Documentation/perf-report.txt

···
 	This allows to examine the path the program took to each sample.
 	The data collection must have used -b (or -j) and -g.
 
+	Also show with some branch flags that can be:
+	- Predicted: display the average percentage of predicated branches.
+		     (predicated number / total number)
+	- Abort: display the number of tsx aborted branches.
+	- Cycles: cycles in basic block.
+
+	- iterations: display the average number of iterations in callchain list.
+
 --addr2line=<path>::
         Path to addr2line binary.
 

tools/perf/Documentation/perf-sched.txt

···
 	priorities are specified with -: 120-129. A combination of both can also be
 	provided: 0,120-129.
 
+-P::
+--pre-migrations::
+	Show pre-migration wait time. pre-migration wait time is the time spent
+	by a task waiting on a runqueue but not getting the chance to run there
+	and is migrated to a different runqueue where it is finally run. This
+	time between sched_wakeup and migrate_task is the pre-migration wait
+	time.

-The struct perf_event_attr test (attr tests) support
-====================================================
-This testing support is embedded into perf directly and is governed
-by the PERF_TEST_ATTR environment variable and hook inside the
-sys_perf_event_open function.
-
-The general idea is to store 'struct perf_event_attr' details for
-each event created within single perf command. Each event details
-are stored into separate text file. Once perf command is finished
-these files are checked for values we expect for command.
-
-The attr tests consist of following parts:
-
-tests/attr.c
-------------
-This is the sys_perf_event_open hook implementation. The hook
-is triggered when the PERF_TEST_ATTR environment variable is
-defined. It must contain name of existing directory with access
-and write permissions.
-
-For each sys_perf_event_open call event details are stored in

-tests/attr.py
--------------
-This is the python script that does all the hard work. It reads
-the test definition, executes it and checks results.
-
-tests/attr/
------------
-Directory containing all attr test definitions.
-Following tests are defined (with perf commands):

···
+The struct perf_event_attr test (attr tests) support
+====================================================
+This testing support is embedded into perf directly and is governed
+by the PERF_TEST_ATTR environment variable and hook inside the
+sys_perf_event_open function.
+
+The general idea is to store 'struct perf_event_attr' details for
+each event created within single perf command. Each event details
+are stored into separate text file. Once perf command is finished
+these files are checked for values we expect for command.
+
+The attr tests consist of following parts:
+
+tests/attr.c
+------------
+This is the sys_perf_event_open hook implementation. The hook
+is triggered when the PERF_TEST_ATTR environment variable is
+defined. It must contain name of existing directory with access
+and write permissions.
+
+For each sys_perf_event_open call event details are stored in
+separate file. Besides 'struct perf_event_attr' values we also
+store 'fd' and 'group_fd' values to allow checking for groups.

+tests/attr.py
+-------------
+This is the python script that does all the hard work. It reads
+the test definition, executes it and checks results.
+
+tests/attr/
+-----------
+Directory containing all attr test definitions.
+Following tests are defined (with perf commands):
