Subject: [RFC 0/3] perf tool: Add non-architectural event aliases

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
