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) [1] https://lore.kernel.org/kvm/96170437-1e00-7841-260e-39d181e7886d@xxxxxxxxx/T/#t Please check each commit message for more details and let me know if there is any room for improvement, Thanks.
