Ah - I see your concern. Yes - it might well be different. Is this information passed in an HVM save record? It does not appear to be associated with the MTRR HVM save record.No , this is the internal state not the save record but Razvan is implementing the same logic in libxc which must necessarily be based on the hvm saved state only and not the internal emulation state. Exactly, and all I need extra an extra variable in the save record (or simply a single bit in a safe place in one of the existing ones), telling me if the MTRRs are overlapped or not. The CPUID code is just a part of the logic that finds this out in the hypervisor; and specifically it is a part that's better _left_in_ the hypervisor. That is in fact what I was trying to say a few messages ago, when I called the cpuid_eax() function the tricky part. :) Do we agree that a bool_t overlapped should be added to struct hvm_hw_mtrr for this case?
