From mboxrd@z Thu Jan 1 00:00:00 1970 From: Joerg Roedel Subject: [PATCH 0/6] KVM: SVM: Wrap access to intercept masks into functions Date: Tue, 30 Nov 2010 18:03:55 +0100 Message-ID: <1291136641-4874-1-git-send-email-joerg.roedel@amd.com> Mime-Version: 1.0 Content-Type: text/plain Cc: , To: Avi Kivity , Marcelo Tosatti Return-path: Sender: linux-kernel-owner@vger.kernel.org List-Id: kvm.vger.kernel.org Hi Avi, Hi Marcelo, this patchset wraps the access to the intercept vectors in the VMCB into specific functions. There are two reasons for this: 1) In the nested-svm code the effective intercept masks are calculated from the host and the guest intercept masks. Whenever KVM changes the host intercept mask while the VCPU is in guest-mode the effective intercept masks need to be re-calculated. This is nicely wrapped into these functions now and makes the code more robust. 2) These changes make the implementation of the upcoming vmcb-clean-bits feature easier and also more robust (which was the main reason for writing this patchset). These patches were developed on-top of the patch-set I sent yesterday. I tested these patches with various guests (Windows-64, Linux 32,32e and 64 as well as with nested-svm).
