Subject: [PATCH v7 00/12] KVM: x86: Add AMD Guest PerfMonV2 PMU support
Date: Fri, 2 Jun 2023 18:10:46 -0700 [thread overview]
Message-ID: <20230603011058.1038821-1-seanjc@google.com> (raw)
v7 of AMD PMU v2 support. This includes the global_ovf_ctrl_mask =>
global_status_mask rename that I *just* posted. I really wanted to apply
v6 and be done with this series, and so sent it out separately, but the
code movement from pmu_intel.c to common x86 was too buggy to do in fixup.
Lightly tested (it's late, it's Friday).
v7:
- Massage/rewrite changelogs to use preferred style.
- Actually move PERF_GLOBAL_CTRL and friends out of pmu_intel.c.
- Move intel_pmu_has_perf_global_ctrl() to common code instead of open
coding it.
- Split moving pmc_is_enabled() out to a separate patch.
- Rebase on the s/global_ovf_ctrl_mask/global_status_mask rename

v5: https://lore.kernel.org/all/20230410105056.60973-1-likexu@tencent.com
v4: https://lore.kernel.org/kvm/20230214050757.9623-1-likexu@tencent.com
