Hello,
I know this is not the right forum for this, but i am looking for
the recent specification/documentation of the AMD NPT and SVM
features. All i can find is the old pacifica document dating back to
2005, and only the NPT whitepaper.
The technical SVM documentation is in the AMD64 Architecture
Programmer's Manual (APM) Volume 2:
http://support.amd.com/us/Processor_TechDocs/24593_APM_v2.pdf
SVM is detailed in chapter 15, with appendix B & C containing the needed
bits for the data structures. Other chapters in this document contain
details about paging, though this is mostly not AMD specific.
Regards,
Andre.
The reason i seek this documentation is that i wish to modify some
KVM code. Specifically, i am interested in how the hardware
sets/resets the accessed/dirty bits of the guest/nested tables
[https://lkml.org/lkml/2011/6/22/20]
Any help will be appreciated.
