AMD Navi support coming to OpenPOWER

Most of us (including yours truly) are using Polaris or Vega AMD GPUs, and the BTO WX7100 option Raptor offers is Polaris, but Raptor has issued kernel patches to enable the latest Navi GPUs on OpenPOWER. This issue was traced back to code essentially locking Navi support to x86, and the new patches have been confirmed working on Void Linux's Power ISA port and Fedora 31. To make the most of these changes, you should also upgrade to at least Mesa 19.3 and LLVM 9.0.1 when these become finalized to avoid various other cross-platform issues with Navi. Still, more hardware support is good support, and the changes are straightforward enough that they should get accepted into the kernel relatively soon.
