This patchset adds IO mode: instead of process time we record io syscalls
and then draw timechart of writes/reads/tx/rx/polls.
v5:
- converted consistency check errors to warnings so we can tolerate
some perf.data errors
- added more info to 'implement IO mode' changelog
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):
