Subject: Re: [PATCH v12 01/11] perf/x86: Fix variable types for LBR registers

Hi Paolo,

As you may know, we have got host perf support in Linus' tree
which provides a clear path for enabling guest LBR,

will we merge the remaining LBR KVM patch set?

[PATCH RESEND v13 00/10] Guest Last Branch Recording Enabling
https://lore.kernel.org/kvm/20201030035220.102403-1-like.xu@linux.intel.com/

Thanks,
Like Xu
