[Xen-devel] [PATCH 0/5] svm: implement new DecodeAssist feature
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.
