Subject: [PATCH 0/2] KVM: x86/mmu: Fast CR3 switch improvements
Date: Fri, 28 Feb 2020 14:52:38 -0800 [thread overview]
Message-ID: <20200228225240.8646-1-sean.j.christopherson@intel.com> (raw)
Two improvements for fast CR3 switch, implemented with nested VMX in mind,
but they should be helpful in general.
Sean Christopherson (2):
KVM: x86/mmu: Ignore guest CR3 on fast root switch for direct MMU
KVM: x86/mmu: Reuse the current root if possible for fast switch
