Yes, nRIP is required and it will be hard to find AMD processor with SVM
support that doesn't have it. We used Phenom II for bhyve port on AMD which
is 2+ years old and has RVI and nRIP support. I use
http://instlatx64.atw.hu/ to check SVM CPUID capability and looks like
after Phenom II, all of them have both of SVM features.

CPUID func 8000000A: 00000001-00000040-00000000-0000000F

                                                      ^^

reg[0] LSB = 0x0F indicate that it has NP/RVI(Bit0) and nRIP(bit3) support.

Anish
