I've added that to the current diff:
"The OpteronG[345] CPU models require KVM support for RDTSCP, which was added with Linux 4.5."
In the meantime, I tried executing RDTSCP on a K8 laptop and it gave SIGILL so I'd say the AMD docs have a typo and family 0xf - at least the A-E revisions of which model 6 is a part of - doesn't have RDTSCP.
But let's see...
Thx.
