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"

perf parser: Add support to specify rXXX event with pmu

The current rXXXX event specification creates event under PERF_TYPE_RAW
pmu type. This change allows to use rXXXX within pmu syntax, so it's
type is used via the following syntax:

-e 'cpu/r3c/'
-e 'cpum_cf/r0/'

The XXXX number goes directly to perf_event_attr::config the same way as
in '-e rXXXX' event. The perf_event_attr::type is filled with pmu type.

Committer testing:

So, lets see what goes in perf_event_attr::config for, say, the
'instructions' PERF_TYPE_HARDWARE (0) event, first we should look at how
to encode this event as a PERF_TYPE_RAW event for this specific CPU, an
AMD Ryzen 5:

# cat /sys/devices/cpu/events/instructions
event=0xc0
#

Then try with it _and_ the instruction, just to see that they are close
enough:

# perf stat -e rc0,instructions sleep 1

Performance counter stats for 'sleep 1':

919,794 rc0
919,898 instructions

1.000754579 seconds time elapsed

0.000715000 seconds user
0.000000000 seconds sys
#

Now we should try, before this patch, the PMU event encoding:

# perf stat -e cpu/rc0/ sleep 1
event syntax error: 'cpu/rc0/'
\___ unknown term

valid terms: event,edge,inv,umask,cmask,config,config1,config2,name,period,percore
#

Now with this patch, the three ways of specifying the 'instructions' CPU
counter are accepted:

# perf stat -e cpu/rc0/,rc0,instructions sleep 1

Performance counter stats for 'sleep 1':

892,948 cpu/rc0/
893,052 rc0
893,156 instructions

1.000931819 seconds time elapsed

0.000916000 seconds user
0.000000000 seconds sys

cldemote, encls, enclu, enclv, enqcmd, enqcmds, movdir64b,
movdiri, pconfig, tpause, umonitor, umwait, wbnoinvd.

- The instruction decoding can be tested using the perf tools'

callchains:

Adrian Hunter:

- Fix segfault in thread__resolve_callchain_sample().

perf probe:

- Line fixes to show only lines where probes can be used with 'perf probe -L',
and when reporting them via 'perf probe -l'.

- Support multiprobe events.

perf scripts python:

Adrian Hunter:

- Fix use of TRUE with SQLite < 3.23 in exported-sql-viewer.py.

perf maps:

- Trim 'struct map' by removing the rb_node member for sorting
by map name, as that is only needed for processing kernel maps,
and only when classifying symbols by section at load time.
Sort them by name using qsort() and do lookups using bsearch()
when map_groups__find_by_name() is used.

perf parse:

Ian Rogers:

- Report initial event parsing error, providing a less cryptic message
to state that a PMU wasn't found in the system.

perf vendor events:

James Clark:

- Fix commas so that PMU event files for arm64, power8 and power nine
become valid JSON.

libtraceevent:

- Fix parsing of event %o and %X argument types.
