From 0e85188049afacdfce9c026144142264981bbabb Mon Sep 17 00:00:00 2001 From: Sheng Yang Date: Fri, 18 Dec 2009 16:48:46 +0800 Subject: KVM: Add cpuid_update() callback to kvm_x86_ops Sometime, we need to adjust some state in order to reflect guest CPUID setting, e.g. if we don't expose rdtscp to guest, we won't want to enable it on hardware. cpuid_update() is introduced for this purpose. Also export kvm_find_cpuid_entry() for later use.
