[PATCH v3 0/3] perf timechart io mode

From: Stanislav Fomichev
Date: Thu Jun 19 2014 - 08:23:47 EST


This patchset adds IO mode: instead of process time we record io syscalls
and then draw timechart of writes/reads/tx/rx/polls.

v3:
- fixed segfault when skipping invalid tracepoints
- added ms/us units support for --io-xyz time options
- fixed missing boxes on Firefox

v2:
- separated start_time fix into distinct commit
- separated --io-xyz options into distinct commit
- fixed 'error' shadowing
- initialized variables in declaration when possible
- removed assert usage
- fprintf -> pr_err
- removed wrongly placed __maybe_unused

Stanislav Fomichev (3):
perf timechart: implement IO mode
perf timechart: conditionally update start_time on fork
perf timechart: add more options to IO mode
