Subject[PATCH v3 0/3] KVM: x86/pmu: Enable guest PEBS for SPR and later models
Date
Hi,

Finally, SPR will go live in early 2023. Virtualization support for SPR
PEBS (kvm.x86.vpmu.pebs_ept) has officially available in the Intel SDM
(June 2022), and this patch set is validated on a late stepping machine.

Let's see if this new revision will satisfy everyone's appetite.

Previous:

V2 -> V3 Changelog:
- Add more commit message about the pdit/pdir stuff; (Sean)
- Refine confusing comments on event precise level and TNT+; (Sean)
- Use pmc_get_pebs_precise_level() instead of need_max_precise(); (Sean)
- Move HYBRID_CPU change in a separate patch; (Sean)
- Land KVM changes before perf core changes; (Sean)
- Aalign code indentation; (Sean) // VScode is quite good for kernel dev.

Like Xu (3):
KVM: x86/pmu: Disable guest PEBS on hybird cpu due to heterogeneity
KVM: x86/pmu: Add PRIR++ and PDist support for SPR and later models
perf/x86/intel: Expose EPT-friendly PEBS for SPR and future models
