[PATCH 0/2] KVM: SVM: Add fast MMIO bus writes
From: Sean Christopherson
Date: Thu Nov 13 2025 - 17:16:45 EST
Add support for expediting fast MMIO bus writes in SVM's npt_interception()
to match VMX's support in handle_ept_misconfig().
I don't recall what prompted me to write the patches; I suspect it was a
"well, why not?" situation. They've been sitting in one of my bajillion
branches since May, and I rediscovered them while looking for something
else.

KVM: SVM: Rename "fault_address" to "gpa" in npf_interception()
KVM: SVM: Add support for expedited writes to the fast MMIO bus
