Summary: POWER8 and POWER9 use a single CPU register, per core, to change clock speed. Everything else is handled by the on-chip controller. This change necessitates a change to the cpufreq global kernel driver to bump supported levels, as the device tree for these systems can have theoretically 256 different options. On my POWER9 Talos, the list consists of 100 items. At 16.67MHz intervals, that allows for a change of roughly 1.67GHz between lowest and highest. This has only been tested on the POWER9. However, since they're similar, this should work on POWER8 as well. Reviewed By: nwhitehorn Differential Revision: https://reviews.freebsd.org/D15932 |

FreeBSD
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
