I don't understand the higher-level purpose of this MTRR support, since HVM guests don't currently do direct I/O. 2. MTRR MSRs are architectural -- the big blob of support you've added for those belongs in an hvm-generic file. In general I think we need common msr read/write functions for dealing with non-processor-specific MSRs. There's way too much almost-identical or actually-identical vmx and svm-specific code right now. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
