Subject: [PATCH 0/3] nVMX: Emulated Page Modification Logging for Nested Virtualization
Date: Wed, 3 May 2017 18:14:54 -0400 [thread overview]
Message-ID: <20170503221457.18869-1-bsd@redhat.com> (raw)
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.
