From mboxrd@z Thu Jan 1 00:00:00 1970 From: Andres Lagar-Cavilla Subject: [PATCH 0 of 3] RFC Paging support for AMD NPT V2 Date: Wed, 29 Feb 2012 22:15:55 -0500 Message-ID: Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Return-path: List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Sender: xen-devel-bounces@lists.xen.org Errors-To: xen-devel-bounces@lists.xen.org To: xen-devel@lists.xensource.com Cc: olaf@aepfle.de, andres@gridcentric.ca, tim@xen.org, wei.wang2@amd.com, hongkaixing@huawei.com, adin@gridcentric.ca List-Id: xen-devel@lists.xenproject.org There has been some progress, but still no joy. Definitely not intended for inclusion at this point. Tim, Wei, I added a Xen command line toggle to disable IOMMU and P2M table sharing. Tim, I verified that changes to p2m-pt.c don't break shadow mode (64bit hypervisor and Win 7 guest). Hongkaixing, I incorporated your suggestion in patch 2, so I should add your Signed-off-by eventually. Please review. Olaf, I do not see errors when mapping pages prior to eviction. Let me know how it goes for you. If I unleash xenpaging on a domain for a non-ambitious target (64 MiBs paged out for one minute), we sail by just fine. But if I kick things up a notch, still dying on an VMEXIT_SHUTDOWN (a.k.a. triple fault). Not sure at all what to do next.
