Subject: [PATCH v3 0/3] KVM: x86/pmu: Enable guest PEBS for SPR and later models
Date: Wed,  9 Nov 2022 16:27:59 +0800	[thread overview]
Message-ID: <20221109082802.27543-1-likexu@tencent.com> (raw)

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:
https://lore.kernel.org/kvm/20220922051929.89484-1-likexu@tencent.com/
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.
