Answering my own question, looks like preliminary Radeon RX Vega support landed in Linux 4.12 with full support in 4.14/15. So it seems there is no additional Radeon GPU supported in drm-next-kmod (Linux 4.11) that isn't already supported in drm-stable-kmod (Linux 4.9). The differences seem to be down to improvements in VM drivers and power management. Please let me know if you have other information. Another question, is it possible to estimate work/time before Wayland/drm-kmod on FreeBSD supports Linux 4.12/14/15 or NVidia cards? GrzegorzJ
