[PATCH v4 0/4] perf timechart io mode

[Stanislav Fomichev]

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

v4:
  - another attempt for fix segfault when skipping invalid tracepoints
  - added new patch to fix rendering in Firefox

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 (4):
  perf timechart: fix rendering in Firefox
  perf timechart: implement IO mode
  perf timechart: conditionally update start_time on fork
  perf timechart: add more options to IO mode
