Subject[PATCH 0/4] KVM: x86/pmu: An insightful refactoring of vPMU code
Date
Hi,

This patch set is essentially triggered by Jim's patch set[1]
(especially patch 01 and 04).

The new idea to set up and maintain pmc->eventsel for fixed counters.
This would unify all fixed/gp code logic based on the same semantics
"pmc->eventse". (I demonstrated this in patch 01-03, more can be done)

Please check each commit message for more details
and let me know if there is any room for improvement,

Thanks.
