From: Kan Liang <kan.li...@intel.com>
This patchkit adds the ability to turn off callgraphs and time stamps
per event. This in term can reduce sampling overhead and the size of
the perf.data.
Changes since V1:
- Break up V1 patches into three patches(parse option changes,
partial time support and partial callgrap support).
- Use strings 'fp,dwarf,lbr,no' to identify callchains
- Add test case in parse-events.c
Changes since V2:
- Rebase on 60cd37eb10
Kan Liang (5):
perf,tools: introduce OPT_CALLBACK_SET/OPT_CALLBACK_NOOPT_SET
perf/documentation: Add description for period
perf,tool: partial time support
perf,tool: partial callgrap support
perf,tests: Add tests to callgrap and time parse
