Merge tag 'perf-core-2020-06-01' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull perf updates from Ingo Molnar:
"Kernel side changes:

- Add AMD Fam17h RAPL support

- Introduce CAP_PERFMON to kernel and user space

- Add Zhaoxin CPU support

- Misc fixes and cleanups

Tooling changes:

- perf record:

Introduce '--switch-output-event' to use arbitrary events to be
setup and read from a side band thread and, when they take place a
signal be sent to the main 'perf record' thread, reusing the core
for '--switch-output' to take perf.data snapshots from the ring
buffer used for '--overwrite', e.g.:

# perf record --overwrite -e sched:* \
--switch-output-event syscalls:*connect* \
workload

will take perf.data.YYYYMMDDHHMMSS snapshots up to around the
connect syscalls.

Add '--num-synthesize-threads' option to control degree of
parallelism of the synthesize_mmap() code which is scanning
/proc/PID/task/PID/maps and can be time consuming. This mimics
pre-existing behaviour in 'perf top'.

- perf bench:

Add a multi-threaded synthesize benchmark and kallsyms parsing
benchmark.

- Intel PT support:

Stitch LBR records from multiple samples to get deeper backtraces,
there are caveats, see the csets for details.

Allow using Intel PT to synthesize callchains for regular events.

Add support for synthesizing branch stacks for regular events
(cycles, instructions, etc) from Intel PT data.

Misc changes:

- Updated perf vendor events for power9 and Coresight.

- Add flamegraph.py script via 'perf flamegraph'

- Misc other changes, fixes and cleanups - see the Git log for details

Also, since over the last couple of years perf tooling has matured and
decoupled from the kernel perf changes to a large degree, going
forward Arnaldo is going to send perf tooling changes via direct pull
requests"
