Subject[RFC v1 0/9] PEBS enabling in KVM guest
Date
Intel new hardware introduces some Precise Event-Based Sampling (PEBS)
extensions that output the PEBS record to Intel PT stream instead of
DS area. The PEBS record will be packaged in a specific format when
outputing to Intel PT.

This patch set will enable PEBS functionality in KVM Guest by PEBS
output to Intel PT. The native driver as [1] (still under review).
