Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf updates from Ingo Molnar:
"Kernel side changes:
- Add branch type profiling/tracing support. (Jin Yao)
- Add the PERF_SAMPLE_PHYS_ADDR ABI to allow the tracing/profiling of
physical memory addresses, where the PMU supports it. (Kan Liang)
- Export some PMU capability details in the new
/sys/bus/event_source/devices/cpu/caps/ sysfs directory. (Andi
Kleen)
- Aux data fixes and updates (Will Deacon)
- kprobes fixes and updates (Masami Hiramatsu)
- AMD uncore PMU driver fixes and updates (Janakarajan Natarajan)
On the tooling side, here's a (limited!) list of highlights - there
were many other changes that I could not list, see the shortlog and
git history for details:
UI improvements:
- Implement a visual marker for fused x86 instructions in the
annotate TUI browser, available now in 'perf report', more work
needed to have it available as well in 'perf top' (Jin Yao)
Further explanation from one of Jin's patches:
│ ┌──cmpl $0x0,argp_program_version_hook
81.93 │ ├──je 20
│ │ lock cmpxchg %esi,0x38a9a4(%rip)
│ │↓ jne 29
│ │↓ jmp 43
11.47 │20:└─→cmpxch %esi,0x38a999(%rip)
That means the cmpl+je is a fused instruction pair and they should
be considered together.
- Record the branch type and then show statistics and info about in
callchain entries (Jin Yao)
Example from one of Jin's patches:
# perf record -g -j any,save_type
# perf report --branch-history --stdio --no-children

namespaces support:
- Add initial support for namespaces, using setns to access files in
namespaces, grabbing their build-ids, etc. (Krister Johansen)
perf trace enhancements:
- Beautify pkey_{alloc,free,mprotect} arguments in 'perf trace'
(Arnaldo Carvalho de Melo)
- Add initial 'clone' syscall args beautifier in 'perf trace'
(Arnaldo Carvalho de Melo)
- Ignore 'fd' and 'offset' args for MAP_ANONYMOUS in 'perf trace'
(Arnaldo Carvalho de Melo)
- Beautifiers for the 'cmd' arg of several ioctl types, including:
sound, DRM, KVM, vhost virtio and perf_events. (Arnaldo Carvalho de
Melo)
- Add PERF_SAMPLE_CALLCHAIN and PERF_RECORD_MMAP[2] to 'perf data'
CTF conversion, allowing CTF trace visualization tools to show
callchains and to resolve symbols (Geneviève Bastien)
- Beautify the fcntl syscall, which is an interesting one in the
sense that infrastructure had to be put in place to change the
formatters of some arguments according to the value in a previous
one, i.e. cmd dictates how arg and the syscall return will be
formatted. (Arnaldo Carvalho de Melo
perf stat enhancements:
- Use group read for event groups in 'perf stat', reducing overhead
when groups are defined in the event specification, i.e. when using
{} to enclose a list of events, asking them to be read at the same
time, e.g.: "perf stat -e '{cycles,instructions}'" (Jiri Olsa)
pipe mode improvements:
- Process tracing data in 'perf annotate' pipe mode (David
Carrillo-Cisneros)
- Add header record types to pipe-mode, now this command:
$ perf record -o - -e cycles sleep 1 | perf report --stdio --header
Will show the same as in non-pipe mode, i.e. involving a perf.data
file (David Carrillo-Cisneros)
Vendor specific hardware event support updates/enhancements:
- Update POWER9 vendor events tables (Sukadev Bhattiprolu)
- Add POWER9 PMU events Sukadev (Bhattiprolu)
- Support additional POWER8+ PVR in PMU mapfile (Shriya)
- Add Skylake server uncore JSON vendor events (Andi Kleen)
- Support exporting Intel PT data to sqlite3 with python perf
scripts, this is in addition to the postgresql support that was
already there (Adrian Hunter)"
