perf coresight: Removing miscellaneous debug output (2016-10-24 11:07:47 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
New features:
- Dynamicly change verbosity level by pressing 'V' in the 'perf top/report'
hists TUI browser (Alexis Berlemont)
- Implement 'perf trace --delay' in the same fashion as in 'perf record --delay',
to skip sampling workload initialization events (Alexis Berlemont)
- Make vendor named events case insensitive in 'perf list', i.e.
'perf list LONGEST_LAT' works just the same as 'perf list longest_lat' (Andi Kleen)
- Show instruction bytes and lenght in 'perf script' for Intel PT and BTS (Andi Kleen, Adrian Hunter)
E.g:
% perf record -e intel_pt// foo
% perf script --itrace=i0ns -F ip,insn,insnlen
ffffffff8101232f ilen: 5 insn: 0f 1f 44 00 00
ffffffff81012334 ilen: 1 insn: 5b
ffffffff81012335 ilen: 1 insn: 5d
ffffffff81012336 ilen: 1 insn: c3
ffffffff810123e3 ilen: 1 insn: 5b
ffffffff810123e4 ilen: 2 insn: 41 5c
ffffffff810123e6 ilen: 1 insn: 5d
ffffffff810123e7 ilen: 1 insn: c3
ffffffff810124a6 ilen: 2 insn: 31 c0
ffffffff810124a8 ilen: 9 insn: 41 83 bc 24 a8 01 00 00 01
ffffffff810124b1 ilen: 2 insn: 75 87
- Allow enabling the perf_event_attr.branch_type attribute member: (Andi Kleen)
perf record -e sched:sched_switch,cpu/cpu-cycles,branch_type=any/ ...
- Add unwinding support for jitdump (Stefano Sanfilippo)
Fixes:
- Use raw_syscall:sys_enter timestamp in 'perf trace' (Arnaldo Carvalho de Melo)
Infrastructure:
- Allow jitdump to be built without libdwarf (Maciej Debski)
- Sync x86's syscall table tools/ copy (Arnaldo Carvalho de Melo)
- Fixes to avoid calling die() in library fuctions already propagating other
errors (Arnaldo Carvalho de Melo)
- Improvements to allow libtraceevent to be properly installed in distro
packages (Jiri Olsa)
- Removing coresight miscellaneous debug output (Mathieu Poirier)
- Cache align the 'perf bench futex' worker struct (Sebastian Andrzej Siewior)
Documentation:
- Minor improvements on the documentation of event parameters (Andi Kleen)
- Add jitdump format specification document (Stephane Eranian)
Spelling fixes:
- Fix typo "No enough" to "Not enough" (Alexander Alemayhu)
