Merge tag 'perf-core-for-mingo-5.1-20190311' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent
Pull perf/core improvements and fixes from Arnaldo:
kernel:
Stephane Eranian :
- Restore mmap record type correctly when handling PERF_RECORD_MMAP2
events, as the same template is used for all the threads interested
in mmap events, some may want just PERF_RECORD_MMAP, while some
may want the extra info in MMAP2 records.
perf probe:
Adrian Hunter:
- Fix getting the kernel map, because since changes related to x86 PTI
entry trampolines handling, there are more than one kernel map.
perf script:
Andi Kleen:
- Support insn output for normal samples, i.e.:
perf script -F ip,sym,insn --xed
Will fetch the sample IP from the thread address space and feed it
to Intel's XED disassembler, producing lines such as:
ffffffffa4068804 native_write_msr wrmsr
ffffffffa415b95e __hrtimer_next_event_base movq 0x18(%rax), %rdx
That match 'perf annotate's output.
- Make the --cpu filter apply to PERF_RECORD_COMM/FORK/... events, in
addition to PERF_RECORD_SAMPLE.
perf report:
- Add a new --samples option to save a small random number of samples
per hist entry, using a reservoir technique to select a representative
number of samples.
Then allow browsing the samples using 'perf script' as part of the hist
entry context menu. This automatically adds the right filters, so only
the thread or CPU of the sample is displayed. Then we use less' search
functionality to directly jump to the time stamp of the selected sample.
It uses different menus for assembler and source display. Assembler
needs xed installed and source needs debuginfo.
- Fix the UI browser scripts pop up menu when there are many scripts
available.
perf report:
Andi Kleen:
- Add 'time' sort option. E.g.:
% perf report --sort time,overhead,symbol --time-quantum 1ms --stdio

tools headers:
Arnaldo Carvalho de Melo:
- Update x86's syscall_64.tbl, no change in tools/perf behaviour.
- Sync copies asm-generic/unistd.h and linux/in with the kernel sources.
perf data:
Jiri Olsa:
- Prep work to support having perf.data stored as a directory, with one
file per CPU, that ultimately will allow having one ring buffer reading
thread per CPU.
Vendor events:
Martin Liška:
- perf PMU events for AMD Family 17h.
perf script python:
Tony Jones:
- Add python3 support for the remaining Intel PT related scripts, with
these we should have a clean build of perf with python3 while still
supporting the build with python2.
libbpf:
Arnaldo Carvalho de Melo:
- Fix the build on uCLibc, adding the missing stdarg.h since we use
va_list in one typedef.
