Does freebsd current and freebsd stable 12 fully support all features of AMD Radeon RX 5700, Vega and RX 500 series including the hardware video decoding features? 2. From website, https://wiki.freebsd.org/Graphics#AMD_Graphics, it says "Update drm-stable to Linux 4.16 for FreeBSD 12.0". Does it mean freebsd hardware support or drivers are copied or translated from linux kernel codes? 3. How are freebsd hardware support really developed? In linux kernel mailing list, there are over 2,000 emails per day from hardware vendors such as Intel, AMD, Huawei, Samsung, Sony submitting patches or hardware drivers. What about BSD? I did not find any such equivalence in freebsd after googling. Mark
