[PATCH RFC V2 0/5] partial callgrap and time support

From: kan . liang
Date: Tue Jul 07 2015 - 13:33:27 EST


From: Kan Liang <kan.liang@xxxxxxxxx>

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

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
