Date: Fri, 5 May 2017 15:25:12 -0400 From: Bandan Das <bsd@...hat.com> To: kvm@...r.kernel.org Cc: pbonzini@...hat.com, linux-kernel@...r.kernel.org Subject: [PATCH v2 0/3] nVMX: Emulated Page Modification Logging for Nested Virtualization v2: 2/3: Clear out all bits except bit 12 3/3: Slightly modify an existing comment, honor L0's PML setting when clearing it for L1 v1: http://www.spinics.net/lists/kvm/msg149247.html These patches implement PML on top of EPT A/D emulation (ae1e2d1082ae). When dirty bit is being set, we write the gpa to the buffer provided by L1. If the index overflows, we just change the exit reason before running L1.
