One of the obnoxious consequences of the firmware not being open source is that, even though both RADV and AMDVLK support GPUs as far back as the 7xxx series, the AMDGPU driver required to use them can't be enabled by default. The released firmware for the UVD video decode unit doesn't support the framebuffer addresses used by AMDGPU, meaning that it can't support hardware video decode until they release an up-to-date firmware: https://lists.freedesktop.org/archives/amd-gfx/2017-November/015795.html https://lists.freedesktop.org/archives/amd-gfx/2017-November... So far users have been waiting for over a year and heard only silence. I suspect, given their attitude to older hardware, the required firmware will never be released.
