Finding AMD processors with NPT/RVI virtualization support?

I'm searching for a CPU with the Nested Page tables (NPT) a.k.a. Rapid Virtualization Indexing (RVI) extension.

Reason is to run hardware-enforced memory virtualization using SLAT under the newest hypervisors.

First I checked if my current CPU has NPT:

For windows: http://www.howtogeek.com/73318/how-to-check-if-your-cpu-supports-second-level-address-translation-slat/

For linux: http://www.cyberciti.biz/faq/linux-xen-vmware-kvm-intel-vt-amd-v-support/

Or: http://www.cyberciti.biz/faq/linux-display-cpu-information-number-of-cpus-and-their-speed/

 

Typing the command: # less /proc/cpuinfo did not show a NPT flag. Meaning, my AMD A8-7600 CPU does not support it.

 

Then I tried to find out which CPU's do.

The only thing I found was this list: http://support.amd.com/en-us/kb-articles/Pages/GPU120AMDRVICPUsHyperVWin8.aspx

But this seems a bit outdated as only older processor families are included.

 

Question: How can I find AMD processors with NPT/RVI?

 

Cheers
