Subject: [RFC PATCH 0/3] kvm: x86: Cleanup and optimazation of switch_db_regs
Date: Thu, 16 Apr 2020 18:15:06 +0800	[thread overview]
Message-ID: <20200416101509.73526-1-xiaoyao.li@intel.com> (raw)

Through reading debug related codes in kvm/x86, I found the flags of
switch_db_regs is a little confusing (at least for me) and there is
something to improve. So this patchset comes. But it only go througg
compilation.

Xiaoyao Li (3):
  kvm: x86: Rename KVM_DEBUGREG_RELOAD to KVM_DEBUGREG_NEED_RELOAD
  kvm: x86: Use KVM_DEBUGREG_NEED_RELOAD instead of
    KVM_DEBUGREG_BP_ENABLED
  kvm: x86: skip DRn reload if previous VM exit is DR access VM exit
