Merge tag 'perf-tools-for-v5.17-2022-01-16' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

Pull perf tool updates from Arnaldo Carvalho de Melo:
"New features:

- Add 'trace' subcommand for 'perf ftrace', setting the stage for
more 'perf ftrace' subcommands. Not using a subcommand yields the
previous behaviour of 'perf ftrace'.

- Add 'latency' subcommand to 'perf ftrace', that can use the
function graph tracer or a BPF optimized one, via the -b/--use-bpf
option.

E.g.:

$ sudo perf ftrace latency -a -T mutex_lock sleep 1

The original implementation of this command was in the bcc tool.

- Support --cputype option for hybrid events in 'perf stat'.

Improvements:

- Call chain improvements for ARM64.

- No need to do any affinity setup when profiling pids.

- Reduce multiplexing with duration_time in 'perf stat' metrics.

- Improve error message for uncore events, stating that some event
groups are can only be used in system wide (-a) mode.

- perf stat metric group leader fixes/improvements, including arch
specific changes to better support Intel topdown events.

- Probe non-deprecated sysfs path first, i.e. try the path
/sys/devices/system/cpu/cpuN/topology/thread_siblings first, then
the old /sys/devices/system/cpu/cpuN/topology/core_cpus.

- Disable debuginfod by default in 'perf record', to avoid stalls on
distros such as Fedora 35.

- Use unbuffered output in 'perf bench' when pipe/tee'ing to a file.

- Enable ignore_missing_thread in 'perf trace'

Fixes:

- Avoid TUI crash when navigating in the annotation of recursive
functions.

- Fix hex dump character output in 'perf script'.

- Fix JSON indentation to 4 spaces standard in the ARM vendor event
files.

- Fix use after free in metric__new().

- Fix IS_ERR_OR_NULL() usage in the perf BPF loader.

- Fix up cross-arch register support, i.e. when printing register
names take into account the architecture where the perf.data file
was collected.

- Fix SMT fallback with large core counts.

- Don't lower case MetricExpr when parsing JSON files so as not to
lose info such as the ":G" event modifier in metrics.

perf test:

- Add basic stress test for sigtrap handling to 'perf test'.

- Fix 'perf test' failures on s/390

- Enable system wide for metricgroups test in 'perf test´.

- Use 3 digits for test numbering now we can have more tests.

Arch specific:

- Add events for Arm Neoverse N2 in the ARM JSON vendor event files

- Support PERF_MEM_LVLNUM encodings in powerpc, that came from a
single patch series, where I incorrectly merged the kernel bits,
that were then reverted after coordination with Michael Ellerman
and Stephen Rothwell.

- Add ARM SPE total latency as PERF_SAMPLE_WEIGHT.

- Update AMD documentation, with info on raw event encoding.

- Add support for global and local variants of the "p_stage_cyc" sort
key, applicable to perf.data files collected on powerpc.

- Remove duplicate and incorrect aux size checks in the ARM CoreSight
ETM code.

Refactorings:

- Add a perf_cpu abstraction to disambiguate CPUs and CPU map
indexes, fixing problems along the way.

- Document CPU map methods.

UAPI sync:

- Update arch/x86/lib/mem{cpy,set}_64.S copies used in 'perf bench
mem memcpy'

- Sync UAPI files with the kernel sources: drm, msr-index,
cpufeatures.

Build system

- Enable warnings through HOSTCFLAGS.

- Drop requirement for libstdc++.so for libopencsd check

libperf:

- Make libperf adopt perf_counts_values__scale() from tools/perf/util/.

- Add a stat multiplexing test to libperf"

perf vendor events: Rename arm64 arch std event files

perf vendor events: Rename arm64 arch std event files

A previous commit adds pmu events into the files

armv8-common-and-microarch.json
armv8-recommended.json

that are actually specified in an armv9 reference supplement, not armv8.
As such, naming the files with the armv8 prefix seems artificial.

This patch renames the files to reflect that these two files are for
arch std events regardless of whether they are defined in armv8 or
armv9.
