Subject: [PATCH 09/13] KVM: SVM: Add intercept checks for remaining group7 instructions
Date: Fri, 25 Mar 2011 10:29:12 +0100 [thread overview]
Message-ID: <1301045356-25257-10-git-send-email-joerg.roedel@amd.com> (raw)
In-Reply-To: <1301045356-25257-1-git-send-email-joerg.roedel@amd.com>
This patch implements the emulator intercept checks for the
RDTSCP, MONITOR, and MWAIT instructions.
