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->eventsel". (I demonstrated this in patch 01-03, more can be done) v1 -> v2 Changelog: - Rename find_perf_hw_id() to pmc_perf_hw_id(); [Paolo] - Add WARN_ON for amd_pmc_perf_hw_id(); [Paolo] - Add pmc->intr to drop dummy need_overflow_intr(pmc); [Paolo] Previous: https://lore.kernel.org/kvm/20211116122030.4698-1-likexu@xxxxxxxxxxx/T/#t [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.
