From 323c3d809b8bd42d6d557c734d4bdfdefa110445 Mon Sep 17 00:00:00 2001 From: Joerg Roedel Date: Mon, 1 Mar 2010 15:34:37 +0100 Subject: [PATCH] KVM: SVM: Optimize nested svm msrpm merging This patch optimizes the way the msrpm of the host and the guest are merged. The old code merged the 2 msrpm pages completly. This code needed to touch 24kb of memory for that operation. The optimized variant this patch introduces merges only the parts where the host msrpm may contain zero bits. This reduces the amount of memory which is touched to 48 bytes.
