hi,
sending another version of stat scripting.
v5 changes:
- several patches from v4 already taken
- using u16 for cpu number in cpu_map_event
- renamed PERF_RECORD_HEADER_ATTR_UPDATE to PERF_RECORD_EVENT_UPDATE
- moved low hanging fuits patches to the start of the patchset
- patchset tested by Kan Liang, thanks!
v4 changes:
- added attr update event for event's cpumask
- forbig aggregation on task workloads
- some minor reorders and changelog fixes
v3 changes:
- added attr update event to handle unit,scale,name for event
it fixed the uncore_imc_1/cas_count_read/ record/report
- perf report -D now displays stat related events
- some minor and changelog fixes
v2 changes:
- rebased to latest Arnaldo's perf/core
- patches 1 to 11 already merged in
- added --per-core/--per-socket/-A options for perf stat report
command to allow custom aggregation in stat report, please
check new examples below
- couple changelogs changes
The initial attempt defined its own formula lang and allowed
triggering user's script on the end of the stat command:
http://marc.info/?l=linux-kernel&m=136742146322273&w=2
This patchset abandons the idea of new formula language
and rather adds support to:
- store stat data into perf.data file
- add python support to process stat events
Basically it allows to store stat data into perf.data and
post process it with python scripts in a similar way we
do for sampling data.
The stat data are stored in new stat, stat-round, stat-config user events.
stat - stored for each read syscall of the counter
stat round - stored for each interval or end of the command invocation
stat config - stores all the config information needed to process data
so report tool could restore the same output as record
The python script can now define 'stat__<eventname>_<modifier>' functions
to get stat events data and 'stat__interval' to get stat-round data.
See CPI script example in scripts/python/stat-cpi.py.
