Subject: [PATCH 03/12] KVM: SVM: Add clean-bit for IOPM_BASE and MSRPM_BASE
Date: Fri, 3 Dec 2010 11:45:50 +0100	[thread overview]
Message-ID: <1291373159-4822-4-git-send-email-joerg.roedel@amd.com> (raw)
In-Reply-To: <1291373159-4822-1-git-send-email-joerg.roedel@amd.com>

This patch adds the clean bit for the physical addresses of
the MSRPM and the IOPM. It does not need to be set in the
code because the only place where these values are changed
is the nested-svm vmrun and vmexit path. These functions
already mark the complete VMCB as dirty.
