Merge tag 'perf-tools-for-v6.3-1-2023-02-22' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

Pull perf tools updates from Arnaldo Carvalho de Melo:
"Miscellaneous:

- Add Ian Rogers to MAINTAINERS as a perf tools reviewer.

- Add support for retire latency feature (pipeline stall of a
instruction compared to the previous one, in cycles) present on
some Intel processors.

- Add 'perf c2c' report option to show false sharing with adjacent
cachelines, to be used in machines with cacheline prefetching,
where accesses to a cacheline brings the next one too.

- Skip 'perf test bpf' when the required kernel-debuginfo package
isn't installed.

- Avoid d3-flame-graph package dependency in 'perf script flamegraph',
making this feature more generally available.

- Add JSON metric events to present CPI stall cycles in Power10.

- Assorted improvements/refactorings on the JSON metrics parsing
code.

perf lock contention:

- Add -o/--lock-owner option:

$ sudo ./perf lock contention -abo -- ./perf bench sched pipe
# Running 'sched/pipe' benchmark:
# Executed 1000000 pipe operations between two processes

Total time: 4.766 [sec]

4.766540 usecs/op

contended total wait max wait avg wait pid owner

1 8.25 us 8.25 us 8.25 us 1583144 sched-pipe
1 2.03 us 2.03 us 2.03 us 5068 chrome

The owner is unknown in most cases. Filtering only for the
mutex locks, it will more likely get the owners.

- -S/--callstack-filter is to limit display entries having the given
string in the callstack:

$ sudo ./perf lock contention -abv -S net sleep 1
...

0xffffffffa5c6467d tcp_keepalive_timer+0x2fd

Please note that to have the -b option (BPF) working above one has
to build with BUILD_BPF_SKEL=1.

- Add more 'perf test' entries to test these new features.

perf script:

- Add 'cgroup' field for 'perf script' output:

$ perf record --all-cgroups -- true
$ perf script -F comm,pid,cgroup
true 337112 /user.slice/user-657345.slice/user@657345.service/...
true 337112 /user.slice/user-657345.slice/user@657345.service/...
true 337112 /user.slice/user-657345.slice/user@657345.service/...
true 337112 /user.slice/user-657345.slice/user@657345.service/...

- Add support for showing branch speculation information in 'perf
script' and in the 'perf report' raw dump (-D).

perf record:

- Fix 'perf record' segfault with --overwrite and --max-size.

perf test/bench:

- Switch basic BPF filtering test to use syscall tracepoint to avoid
the variable number of probes inserted when using the previous
probe point (do_epoll_wait) that happens on different CPU
architectures.

- Fix DWARF unwind test by adding non-inline to expected function in
a backtrace.

- Use 'grep -c' where the longer form 'grep | wc -l' was being used.

- Add getpid and execve benchmarks to 'perf bench syscall'.

Intel PT:

- Add support for synthesizing "cycle" events from Intel PT traces as
we support "instruction" events when Intel PT CYC packets are
available. This enables much more accurate profiles than when using
the regular 'perf record -e cycles' (the default) when the workload
lasts for very short periods (<10ms).

- .plt symbol handling improvements, better handling IBT (in the past
MPX) done in the context of decoding Intel PT processor traces,
IFUNC symbols on x86_64, static executables, understanding .plt.got
symbols on x86_64.

- Add a 'perf test' to test symbol resolution, part of the .plt
improvements series, this tests things like symbol size in contexts
where only the symbol start is available (kallsyms), etc.

- Better handle auxtrace/Intel PT data when using pipe mode (perf
record sleep 1|perf report).

- Fix symbol lookup with kcore with multiple segments match stext,
getting the symbol resolution to just show DSOs as unknown.

ARM:

- Timestamp improvements for ARM64 systems with ETMv4 (Embedded Trace
Macrocell v4).

- Ensure ARM64 CoreSight timestamps don't go backwards.

- Document that ARM64 SPE (Statistical Profiling Extension) is used
with 'perf c2c/mem'.

- Add raw decoding for ARM64 SPEv1.2 previous branch address.

- Update neoverse-n2-v2 ARM vendor events (JSON tables): topdown L1,
TLB, cache, branch, PE utilization and instruction mix metrics.

- Update decoder code for OpenCSD version 1.4, on ARM64 systems.

- Fix command line auto-complete of CPU events on aarch64.

Build:

- Fix 'perf probe' and 'perf test' when libtraceevent isn't linked,
as several tests use tracepoints, those should be skipped.

- More fallout fixes for the removal of tools/lib/traceevent/.

- Fix build error when linking with libpfm"

perf script flamegraph: Avoid d3-flame-graph package dependency

Currently flame graph generation requires a d3-flame-graph template to
be installed. Unfortunately this is hard to come by for things like
Debian [1].

If the template isn't installed then ask if it should be downloaded from
jsdelivr CDN. The downloaded HTML file is validated against an md5sum.
If the download fails, generate a minimal flame graph with the
javascript coming from links to jsdelivr CDN.

v3. Adds a warning message and quits before download in live mode.
v2. Change the warning to a prompt about downloading and add the
--allow-download command line flag. Add an md5sum check for the
downloaded HTML.
