From edcafe3c5a06f46407c3f60145a36f269e56ff7f Mon Sep 17 00:00:00 2001 From: Avi Kivity Date: Wed, 30 Dec 2009 18:07:40 +0200 Subject: [PATCH] KVM: VMX: Give the guest ownership of cr0.ts when the fpu is active If the guest fpu is loaded, there is nothing interesing about cr0.ts; let the guest play with it as it will. This makes context switches between fpu intensive guest processes faster, as we won't trap the clts and cr0 write instructions.
