Subjectmeasure uncore events
From
Hello all,

I'm trying to measure uncore events. After reading [1], I tried "perf
stat -a -e "uncore_imc_0/event=0xff,umask=0x00/" /bin/ls", it says
"invalid or unsupported event".

The machine is Intel Ivy Bridge i5-3320M with ArchLinux 3.11.2-1-ARCH.
'perf --version' is 'perf version 3.11.0'
In '/sys/bus/event_source/devices/uncore_cbox_0/events', there is only
one event 'clockticks'.

Did I miss something?

thanks,
yuanfang
