From 890ca9aefa78f7831f8f633cab9e4803636dffe4 Mon Sep 17 00:00:00 2001 From: Huang Ying Date: Mon, 11 May 2009 16:48:15 +0800 Subject: KVM: Add MCE support The related MSRs are emulated. MCE capability is exported via extension KVM_CAP_MCE and ioctl KVM_X86_GET_MCE_CAP_SUPPORTED. A new vcpu ioctl command KVM_X86_SETUP_MCE is used to setup MCE emulation such as the mcg_cap. MCE is injected via vcpu ioctl command KVM_X86_SET_MCE. Extended machine-check state (MCG_EXT_P) and CMCI are not implemented.
