I haven't been able to use Gentoo directly, but I have used Linux on Power on GCC's servers. There's nothing terribly abnormal, though there's a lot of interesting FPU modes. > I noticed that gentoo only has big endian isos instead of little endian and > I am also wondering what this means for software availability as I have > never heard of endianness before a few months ago. > You should use ppc64le. This complicates things when compiling, and is a minor issue for some other compilers, who do not support multilib in a way that makes it possible to build a ppc64le toolchain from a ppc64 toolchain. You may need to set up tools on a computer of another architecture, or get prebuilt tools from GCC. > Info: > https://en.wikipedia.org/wiki/POWER9 (POWER is now the only high performance > arch that is owner controlled now that AMD has its ME analog PSP) > http://raptorcs.com/ (The T2 is a modified "romulus" reference board made > available to the general public with libre firmware) > They are expensive, but one day, if the Lord decides to bless me, I may own one.
