As new capabilities are added to support POWER9 specific features, they will be added to this.

Created attachment 188836 [details] Patch with the fix I currently booted FreeBSD on a POWER9 machine (on top of KVM), and I got the following message: cpu0: Unknown PowerPC CPU revision 0x1201, 2550.00 MHz This is because of POWER9 is not listed as a valid CPU model on FreeBSD code. This patch simply adds it with the same feature set as POWER8 for now, so, new features could be added as they are implemented.
