Subject: RE: perf, x86: Disable PEBS on SandyBridge chips

Hey Peter,

Why is PEBS disabled? If I look at the intel_clovertown_quirks I can see 
why it's disabled for that cpu, but the sandy bridge one lacks any kind 
of clarification or information on why, or how I can learn more.

Cheers,
Maarten
