Hi,
this is the second version of the patch-set to support the AMD guest-/host only bits in the performance counter MSRs. Due to lack of time I havn't looked into emulating support for this feature on Intel or other architectures, but the other comments should be worked in. The changes to v1 include:
* Rebased patches to v3.0-rc3 * Allow exclude_guest and exclude_host set at the same time * Reworked event-parse logic for the new exclude-bits * Only count guest-events per default from perf-kvm
Thats it, unless I forgot something. Any feedback appreciated :-)
Thanks,
Joerg
