Subject: [GIT PULL 00/59] perf/core improvements and fixes
Hi Ingo,
Please consider pulling, more to come, bpf, make build-test and
hopefully Stephane's JIT stuff, etc.
Best Regards,
- Arnaldo
The following changes since commit 9cc2617de5b9222abb39cd02e90d57dfea99c6d7:
perf/x86/amd: Remove l1-dcache-stores event for AMD (2016-01-06 11:15:39 +0100)

perf evlist: Add --trace-fields option to show trace fields (2016-01-08 14:23:02 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
New features:
- Allow using trace events fields as sort order keys, making 'perf evlist --trace_fields'
show those, and then the user can select a subset and use like:
perf top -e sched:sched_switch -s prev_comm,next_comm
That works as well in 'perf report' when handling files containing
tracepoints.
The default when just tracepoint events are found in a perf.data file is to
format it like ftrace, using the libtraceevent formatters, plugins, etc (Namhyung Kim)
- Add support in 'perf script' to process 'perf stat record' generated files,
culminating in a python perf script that calculates CPI (Cycles per
Instruction) (Jiri Olsa)
- Show random perf tool tips in the 'perf report' bottom line (Namhyung Kim)
- perf report now defaults to --group if the perf.data file has grouped events, try it with:
# perf record -e '{cycles,instructions}' -a sleep 1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 1.093 MB perf.data (1247 samples) ]
# perf report
# Samples: 1K of event 'anon group { cycles, instructions }'
# Event count (approx.): 1955219195
#
# Overhead Command Shared Object Symbol

User visible fixes:
- Coect data mmaps so that the DWARF unwinder can handle usecases needing them,
like softice (Jiri Olsa)
- Decay callchains in fractal mode, fixing up cases where 'perf top -g' would
show entries with more than 100% (Namhyung Kim)
Infrastructure:
- Sync tools/lib with the lib/ in the kernel sources for find_bit.c and
move bitmap.[ch] from tools/perf/util/ to tools/lib/ (Arnaldo Carvalho de Melo)
- No need to set attr.sample_freq in some 'perf test' entries that only
want to deal with PERF_RECORD_ meta-events, improve a bit error output
for CQM test (Arnaldo Carvalho de Melo)
- Fix python binding build, adding some missing object files now required
due to cpumap using find_bit stuff (Arnaldo Carvalho de Melo)
- tools/build improvemnts (Jiri Olsa)
- Add more files to cscope/ctags databases (Jiri Olsa)
- Do not show 'trace' in 'perf help' if it is not compiled in (Jiri Olsa)
- Make perf_evlist__open() open evsels with their cpus and threads,
like perf record does, making them consistent (Adrian Hunter)
- Fix pmu snapshot initialization bug (Stephane Eranian)
- Add missing headers in perf's MANIFEST (Wang Nan)
