Subject: [PATCH v3 0/5] KVM: VMX: Clean up RTIT MAXPHYADDR usage
Date: Thu, 24 Sep 2020 12:42:45 -0700 [thread overview]
Message-ID: <20200924194250.19137-1-sean.j.christopherson@intel.com> (raw)
Stop using cpuid_query_maxphyaddr() for a random RTIT MSR check, unexport
said function to discourage future use, and do additional related cleanup.
Paolo, feel free to reorder/squash these as you see fit. Five patches
feels more than a bit gratuitous, but every time I tried to squash things
I ended up with changelogs that ran on and on...
v2:
- Rebased to kvm/queue, commit e1ba1a15af73 ("KVM: SVM: Enable INVPCID
feature on AMD").
Sean Christopherson (5):
KVM: VMX: Use precomputed MAXPHYADDR for RTIT base MSR check
KVM: x86: Unexport cpuid_query_maxphyaddr()
KVM: VMX: Replace MSR_IA32_RTIT_OUTPUT_BASE_MASK with helper function
KVM: x86: Move illegal GPA helper out of the MMU code
KVM: VMX: Use "illegal GPA" helper for PT/RTIT output base check
