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.
