| |
Hello,
The following patch adds to the x86-64 tree a bunch of MSRs related to performance monitoring for the processors based on Intel Core microarchitecture. It also adds some architectural MSRs for PEBS. A similar patch for i386 will follow.
changelog: - add Intel Precise-Event Based sampling (PEBS) related MSR - add Intel Data Save (DS) Area related MSR - add Intel Core microarchitecure performance counter MSRs
