From c845f9c646e646e6a5fe416c2e835342984249f7 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Fri, 21 Feb 2014 10:55:44 +0100 Subject: KVM: vmx: we do rely on loading DR7 on entry Currently, this works even if the bit is not in "min", because the bit is always set in MSR_IA32_VMX_ENTRY_CTLS. Mention it for the sake of documentation, and to avoid surprises if we later switch to MSR_IA32_VMX_TRUE_ENTRY_CTLS.
