Subject: Updated PEBS simplification/fixup patchkit
Date: Fri, 27 Jun 2014 16:10:10 -0700 [thread overview]
Message-ID: <1403910612-8754-1-git-send-email-andi@firstfloor.org> (raw)
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.
-Andi
