Hi,newer AMD SVM implementations (starting with Bulldozer) have some additions to SVM called DecodeAssist. These bits improve and simplify the handling of some intercepts, now more information is provided in the VMCB already and saves us from decoding this information "manually". These new features are described in recent editions of the APM Vol.2 manual, chapter 15.33. The first patch moves some code from VMX into HVM to be later used by SVM. The second patch adds the newly defined bits to VMCB and CPUID. Patch 3 to 5 implement three parts of the feature set, more details in the specific emails. Please comment. All patches: Signed-off-by: Andre Przywara <andre.przywara@xxxxxxx> Regards, Andre. -- Andre Przywara AMD-Operating System Research Center (OSRC), Dresden, Germany _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
