Subject: [RFCv2 0/8] perf tools: Add non-architectural event aliases

hi,
adding support to use non-architectural events in perf via name,
to be able to use them like:

$ perf stat -e 'cpu/IDQ.ALL_DSB_CYCLES/' ...
$ perf stat -e 'cpu/L2_STORE_LOCK_RQSTS.MISS/' ...
...

The perf list command displays current non-arch. events available:

$ perf list
...
  cpu/AGU_BYPASS_CANCEL.COUNT/                       [Kernel PMU event]
  cpu/ARITH.FPU_DIV/                                 [Kernel PMU event]
  cpu/ARITH.FPU_DIV_ACTIVE/                          [Kernel PMU event]
  cpu/BACLEARS.ANY/                                  [Kernel PMU event]
...

This version is dependent on precise changes:
http://marc.info/?l=linux-kernel&m=135922143117888&w=2

First version of this RFC is here:
http://marc.info/?l=linux-kernel&m=135575146128720&w=2

This version provides support for non-architectural events
aliasses being defined in sigle files, like for SandyBridge:

$ cat arch/x86/events/intel/snb | head -5
name=AGU_BYPASS_CANCEL.COUNT,event=0xb6,umask=0x1
name=ARITH.FPU_DIV_ACTIVE,event=0x14,umask=0x1
name=ARITH.FPU_DIV,event=0x14,umask=0x10401
name=BACLEARS.ANY,event=0xe6,umask=0x1f
...

So far this is still under testing and only SandyBridge and IvyBridge
events were added. I have no problem to add the rest of the archs.
when the shape of this is agreed.

any comments are welcome,
