Wymagane pakiety i sterowniki

Do rc.conf

rc.conf

kld_list="amdgpu amdtemp acpi_ibm acpi_call"

Z portów potrzebny będzie utilek do sterowania acpi oraz sterowniki drm do karty graficznej i firmware do GPU i Bluetooth:

pkg install acpi_call drm-61-kmod gpu-firmware-amd-kmod-picasso gpu-firmware-amd-kmod-raven iwmbt-firmware

Akceleracja Video

Dorzucamy:

pkg install graphics/mesa-gallium-va multimedia/libva-utils

W Firefox odpalamy about:config i ustawiamy:

media.hardware-video-decoding.force-enabled=true

Zasilanie
