Subject: [PATCH v4 RESEND 0/5] x86: The perf/x86 changes to support guest Arch LBR
Date: Mon, 22 Mar 2021 14:06:30 +0800	[thread overview]
Message-ID: <20210322060635.821531-1-like.xu@linux.intel.com> (raw)

Hi Peter,

Please help review these minor perf/x86 changes in this patch set,
and we need some of them to support Guest Architectural LBR in KVM.

If you are interested in the KVM emulation, please check
https://lore.kernel.org/kvm/20210314155225.206661-1-like.xu@linux.intel.com/

Please check more details in each commit and feel free to comment.

Like Xu (5):
  perf/x86/intel: Fix the comment about guest LBR support on KVM
  perf/x86/lbr: Simplify the exposure check for the LBR_INFO registers
  perf/x86/lbr: Move cpuc->lbr_xsave allocation out of sleeping region
  perf/x86/lbr: Skip checking for the existence of LBR_TOS for Arch LBR
  perf/x86: Move ARCH_LBR_CTL_MASK definition to include/asm/msr-index.h
