Merge tag 'perf-tools-for-v6.11-2024-07-16' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools
Pull perf tools updates from Namhyung Kim: "Build:
- Build each directory as a library so that depedency check for the python extension module can be automatic
- Use pkg-config to check libtraceevent and libtracefs
perf sched:
- Add --task-name and --fuzzy-name options for `perf sched map`
It focuses on selected tasks only by removing unrelated tasks in the output. It matches the task comm with the given string and the --fuzzy-name option allows the partial matching:
$ sudo perf sched record -a sleep 1
$ sudo perf sched map --task-name kworker --fuzzy-name . . . . - *A0 . . 481065.315131 secs A0 => kworker/5:2-i91:438521 . . . . - *- . . 481065.315160 secs *B0 . . . - . . . 481065.316435 secs B0 => kworker/0:0-i91:437860 *- . . . . . . . 481065.316441 secs . . . . . *A0 . . 481065.318703 secs . . . . . *- . . 481065.318717 secs . . *C0 . . . . . 481065.320544 secs C0 => kworker/u16:30-:430186 . . *- . . . . . 481065.320555 secs . . *D0 . . . . . 481065.328524 secs D0 => kworker/2:0-kdm:429654 *B0 .

- Fix -r/--repeat option of perf sched replay
The documentation said -1 will work as infinity but it didn't accept the value. Update the code and document to use 0 instead
- Fix perf sched timehist to account the delay time for preempted tasks
Perf event filtering:
- perf top gained filtering support on regular events using BPF like perf record. Previously it was able to use it for tracepoints only
- The BPF filter now supports filtering by UID/GID. This should be preferred than -u <UID> option as it's racy to scan /proc to check tasks for the user and fails to open an event for the task if it's already gone
$ sudo perf top -e cycles --filter "uid == $(id -u)"
perf report:
- Skip dummy events in the group output by default. The --skip-empty option controls display of empty events without samples. But perf report can force display all events in a group
In this case, auto-added a dummy event (for a system-wide record) ends up in the output. Now it can skip those empty events even in the group display mode
To preserve the old behavior, run this:
$ perf report --group --no-skip-empty
perf stat:
- Choose the most disaggregate option when multiple aggregation options are given. It used to pick the last option in the command line but it can be confusing and not consistent. Now it'll choose the smallest unit
For example, it'd aggregate the result per-core when the user gave both --per-socket and --per-core options at the same time
Internals:
- Fix `perf bench` when some CPUs are offline
- Fix handling of JIT symbol mappings to accept "/tmp/perf-${PID}.map patterns only so that it can not be confused by other /tmp/perf-* files
- Many improvements and fixes for `perf test`
Others:
- Support some new instructions for Intel-PT
- Fix syscall ID mapping in perf trace
- Document AMD IBS PMU usages
- Change `perf lock info` to show map and thread info by default
Vendor JSON events:
- Update Intel events and metrics
- Add i.MX9[35] DDR metrics"

- Various fixes and cleanups for event metrics including NaN handling
perf script:
- Use libcapstone if available to disassemble the instructions. This enables 'perf script -F disasm' and 'perf script --insn-trace=disasm' (for Intel-PT):
$ perf script -F event,ip,disasm cycles:P: ffffffffa988d428 wrmsr cycles:P: ffffffffa9839d25 movq %rax, %r14 cycles:P: ffffffffa9cdcaf0 endbr64 cycles:P: ffffffffa988d428 wrmsr cycles:P: ffffffffa988d428 wrmsr cycles:P: ffffffffaa401f86 iretq cycles:P: ffffffffa99c4de5 movq 0x30(%rcx), %r8 cycles:P: ffffffffa988d428 wrmsr cycles:P: ffffffffaa401f86 iretq cycles:P: ffffffffa9907983 movl 0x68(%rbx), %eax cycles:P: ffffffffa988d428 wrmsr
- Expose sample ID / stream ID to python scripts
perf test:
- Add more perf test cases from Redhat internal test suites. This time it adds the base infra and a few perf probe tests. More to come. :)
- Add 'perf test -p' for parallel execution and fix some issues found by the parallel test
- Support symbol test to print symbols in given (active) module:
$ perf test -F -v Symbols --dso /lib/modules/$(uname -r)/kernel/fs/ext4/ext4.ko --- start --- Testing /lib/modules/6.5.13-1rodete2-amd64/kernel/fs/ext4/ext4.ko Overlapping symbols: 7a990-7a9a0 l __pfx_ext4_exit_fs 7a990-7a9a0 g __pfx_cleanup_module Overlapping symbols: 7a9a0-7aa1c l ext4_exit_fs 7a9a0-7aa1c g cleanup_module ...
JSON metric updates:
- A new round of Intel metric updates
- Support Power11 PVR (compatible to Power10)
- Fix cache latency events on Zen 4 to set SliceId properly
Internal:
- Fix reference counting for 'map' data structure, tireless work from Ian!
- More memory optimization for struct thread and annotate histogram. Now, 'perf report' (TUI) and 'perf annotate' should be much lighter-weight in terms of memory footprint
- Support cross-arch perf register access. Clean up the build configuration so that it can detect arch-register support at runtime. This can allow to parse register data in sample which was recorded in a different arch
Others:
- Sync task state in 'perf sched' to kernel using trace event fields. The task states have been changed so tools cannot assume a fixed encoding
- Clean up 'perf mem' to generalize the arch-specific events
- Add support for local and global variables to data type profiling. This would increase the success rate of type resolution with DWARF
- Add short option -H for --hierarchy in 'perf report' and 'perf top'"
