[RFC 0/3] perf tool: Add non-architectural event aliases
From: Jiri Olsa
Date: Mon Dec 17 2012 - 08:37:17 EST
hi,
adding support to use non-architectural events in perf via name.
Attached patches:
1/3 perf tool: Add '.' as part of the event 'name' token
2/3 perf tool: Add support to include non architectural event aliases
3/3 perf tool: Add non arch events for SandyBridge microarchitecture
Basically, the pmu alias code detects the architecture and tries
to find 'events' directory with non-architectural aliases.
For each non-architectural event there needs to be special file
containig the event definition using pmu 'format' style, like:
$ cat arch/x86/events/intel/SandyBridge/DTLB_LOAD_MISSES.MISS_CAUSES_A_WALK
event=0x8,umask=0x1
Patch 3 contains part (not whole!) of aliases for SandyBridge microarch
(Intel naming style is used) and can be used like:
$ perf record -e 'cpu/DTLB_LOAD_MISSES.MISS_CAUSES_A_WALK/' ls
The non-architectural event aliases could be part of the kernel
as well as architectural events, under some other 'events' sysfs
attribute.. I wasn't sure though.. looks like lot of perf data ;-)
any comments are welcome,
jirka
