- Extended 'perf annotate' with DWARF type information (--code-with-type) integration in the TUI, including a 'T' hotkey to toggle it
- Enhanced 'perf bench mem' with new mmap() workloads and control over page/chunk sizes
- Fix 'perf stat' error handling to correctly display unsupported events
- Improved support for Clang cross-compilation
- Refactored LLVM and Capstone disasm for modularity
- Introduced the :X modifier to exclude an event from automatic regrouping
- Adjusted KVM sampling defaults to use the "cycles" event to prevent failures
- Added comprehensive support for decoding PowerPC Dispatch Trace Log (DTL)
- Updated Arm SPE tracing logic for better analysis of memory and snoop details
- Synchronized Intel PMU events and metrics with TMA 5.1 across multiple processor generations
- Converted dependencies like libperl and libtracefs to be opt-in
- Handle more Rust symbols in kallsyms ('N', debugging)
- Improve the python binding to allow for python based tools to use more of the libraries, add a 'ilist' utility to test those new bindings
- Various 'perf test' fixes
- Kan Liang no longer a perf tools reviewer

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 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

- 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.

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"
