Subject: [GIT PULL] perf tools changes for v6.2: 1st batch
Hi Linus,
This time there is a trivial resolution of a merge conflict
related to commit c302378bc157f6a7 ("libbpf: Hashmap interface update to
allow both long and void* keys/values"), that touched tools/perf/ files.
Please consider pulling,
Best regards,
- Arnaldo

libperf: Fix install_pkgconfig target (2022-12-16 10:04:06 -0300)
----------------------------------------------------------------
perf tools changes for v6.2: 1st batch
Libraries:
- Drop the old copy of libtraceevent in tools/lib/traceevent/ now that all major distros
ship it from its external repository.
This is now just another feature detection, emitting a warning when the
libtraceevent-dev[el] package isn't installed, disabling the build of perf features
and tools that strictly require parsing things from tracefs while keeping
the core functionality present and working with a subset of the events, the
most used ones like CPU cycles, hardware cache and also vendor events, etc.
This was tested with lots of containers for Fedora, Debian, OpenSUSE, Alpine Linux,
Ubuntu, with cross builds, etc.
Build:
- Update to C standard to gnu11, like was done for the kernel.
- Install the tools/lib/ libraries locally instead of having headers searched
directly from the source code directories, to help the cases where we can
build either from in-kernel source libraries or from the same library shipped
as a distro package, as is the case with libbpf and was the case with
libtraceevent.
perf stat:
- Do not delay the workload with --delay, the delay is just for starting to count
the events, to skip noise at workload startup.
- When we have events for each cgroup, the metric should be printed for each
cgroup separately.
$ perf stat -a --for-each-cgroup system.slice,user.slice --metric-only sleep 1
Performance counter stats for 'system wide':
GHz insn per cycle branch-misses of all branches
system.slice 3.792 0.61 3.24%
user.slice 3.661 2.32 0.37%
- Fix printing field separator in CSV metrics output.
- Fix --metric-only --json output.
- Fix summary output in CSV with --metric-only.
- Update event group check for support of uncore event.
perf test:
- Stop requiring a C toolchain in shell tests, instead add a workload option that has
all the previously C snippets built as part of 'perf test -w' that then get used in
the 'perf test' shell scripts.
- Add event group test for events in multiple PMUs
- The "kernel lock contention analysis" test should not print warnings in quiet mode.
- Add attr tests for ARM64's new VG register.
- Fix record test on KVM guests, as using precise flag with the
br_inst_retired.near_call event causes the test fail on KVM guests, even when
the guests have PMU forwarding enabled and the event itself is supported, so just
remove the precise flag from the event.
- Add mechanism for skipping attr tests on specific kernel versions where it is known that
these checks will fail.
- Skip watchpoint tests if no watchpoints available.
- Add more Intel PT 'perf test' entries: hybrid CPUs, split the packet decoder
into a suite of subtests.
perf script:
- Introduce task analyzer python script, where one first records some events:
Recording can be done in two ways:
$ perf script record tasks-analyzer -- sleep 10
$ perf record -e sched:sched_switch -a -- sleep 10
The script can parse any perf.data files, as long as it has sched:sched_switch events,
other events will be ignored.
The most simple report use case is to just call the script without arguments.
Runtime is the time the task was running on the CPU, Time Out-In is the time
between the process being scheduled *out* and scheduled back *in*. So the last
time span between two executions:
$ perf script report tasks-analyzer
Switched-In Switched-Out CPU PID TID Comm Runtime Time Out-In

[...]
perf lock:
- Allow concurrent record and report to support live monitoring of kernel lock
contention without BPF:
# perf lock record -a -o- sleep 1 | perf lock contention -i-
contended total wait max wait avg wait type caller
2 10.27 us 6.17 us 5.13 us spinlock load_balance+0xc03
1 5.29 us 5.29 us 5.29 us rwlock:W ep_scan_ready_list+0x54

1 3.28 us 3.28 us 3.28 us mutex pipe_read+0x50
- Implement -t/--threads option when using BPF:
$ sudo ./perf lock contention -abt -E 5 sleep 1
contended total wait max wait avg wait pid comm
1 740.66 ms 740.66 ms 740.66 ms 1950 nv_queue
3 305.50 ms 298.19 ms 101.83 ms 1884 nvidia-modeset/

12 23.09 us 9.30 us 1.92 us 0 swapper
1 20.18 us 20.18 us 20.18 us 2725033 EventManager_De
- Add -l/--lock-addr to aggregate per-lock-instance contention:
$ sudo ./perf lock contention -abl sleep 1
contended total wait max wait avg wait address symbol
1 36.28 us 36.28 us 36.28 us ffff92615d6448b8

1 924 ns 924 ns 924 ns ffff926095ba9d20
1 436 ns 436 ns 436 ns ffff9260bfda4f60
perf record:
- Add remaining branch filters: "no_cycles", "no_flags" & "hw_index", to be
used with hardware such as Intel's LBR that allows things like stitching
stacks of two samples to overcome the limits of the number of LBR registers.
Symbol resolution:
- Handle .debug files created with 'objcopy --only-keep-debug', where program
headers are zeroed and thus can't be used for adjustments, use the info in
the runtime_ss (runtime ELF) instead.
perf trace:
- Add BPF based augmenter for the 'perf_event_open's 'struct perf_event_attr' argument.
- Add BPF based augmenter for the 'clock_gettime's 'struct timespec' argument.
- In both cases the syscall tracepoint has just the pointer value, we
need to hook a BPF program to collect the pointer contents, and then,
in userspace, pretty print it in 'perf trace'.
perf list:
- Introduce JSON output of events.
- Streamline how the expression specifying what events should be shown is handled,
fixing several corner cases, such as the metric filter that is specified as a glob
but was using strstr().
perf probe:
- Fix to avoid crashing if DW_AT_decl_file is NULL, coping with clang generating
DWARF5 like that.
- Use dwarf_attr_integrate() as generic DWARF attr accessor as it supersedes dwarf_attr(),
supporting abstact origin DIEs.
perf inject:
- Set PERF_RECORD_MISC_BUILD_ID_SIZE in the PERF_RECORD_HEADER_BUILD_ID so that
perf.data readers can get the real build-id size and avoid trailing zeros.
perf data:
- Add tracepoint fields when converting a perf.data file to JSON.
arm64:
- Fix mksyscalltbl, don't lose syscalls due to sort -nu.
- Add Arm Neoverse V2 PMU events.
riscv:
- Add riscv sbi firmware std event files.
- Add Sifive U74 vendor events (JSON) file.
- Add some more events and metrics for Alderlake/Alderlake-N.
Documentation:
- Add data documentation for the PMU structs in the C source code.
Miscellaneous:
- Periodic sanitization of headers, adding missing includes, removing needless ones,
creating new ones, etc.
- Use sig_atomic_t for signal handlers to avoid undefined behaviour in all perf
tools.
- Fixes for libbpf 1.0+ compatibility (maps, etc) on 'perf trace' BPF examples.
- Remove some old perf bpf examples, leave the best ones that demonstrate how
to associate BPF functions to points in the kernel.
- Make quiet mode consistent between tools.
- Use dedicated non-atomic clear/set bit helpers.
- Use "grep -E" instead of "egrep" as recommended by warning emitted by GNU
grep since at least version 3.8.
- Complete list of supported subcommands in the 'perf daemon' help message.
- Update John Garry's email address for arm64 perf tooling on the MAINTAINERS file,
he moved from Huawei to Oracle.
