This patchkit is my take on how the PEBS event lists should be revampled. Plus a fix for the ANY bit.
It is a superset of Stephane's patches and obsoletes them.
I think I discussed nearly everything in there already in some earlier emails. Basic ideas/fixes:
- Don't list every PEBS event as that's not needed - Check the flags as the SDM recommends - Still allow cycles:pp of course - Fix the counters for memory latency events - Fix the DataLA handling on Haswell to support all events. - Allow leaking events with ANY bit.
Also the patchkit removes more code than it adds, so it's a simplification.
