Re: [perfmon2] No uncore events on Nehalem-EX?

[Vishal G. <vi...@cc...>]

Bump. I've so far found some linux patches to get uncore events  
working with linux perf. Is that my only option? I'm already using  
pfmon for all my work and moving to perf just for this would break  
many other things. pfmon documentation says that it supports uncore  
events for core i7 processors.
http://perfmon2.sourceforge.net/pfmon_intel_corei7.html#uncc

Any help on how to get uncore events working with pfmon?

Thanks,
Vishal
