Someone already posted on this, but they marked it at solved. graphics/gpu-firmware-amd-kmod lists "sienna_cichlid" which is code for the Navi 21 cards. Has anyone gotten this to work? I compiled drm-510-kmod and gpu-firmware-kmod. Loading the amdgpu module is successful. I also built xf86-video-amdgpu from ports, x still fails and there's no /dev/dri/card0. Tried to go without xf86-video-amdgpu too since it isn't listed as a step in the wiki.
The error I get right now:
(EE) Cannot run in framebuffer mode. Please specify busIDs for all framebuffer devices
