Is Radeon RX Vega 64 supported by drm-next?

[Grzegorz Junka]

Hello All

According to various sources (including posts to freebsd-x11) 
drm-stable-kmod supports Polaris (RX 4xx/5xx). Does it mean that 
drm-next-kmod supports RX Vega?

According to Wikipedia Radeon RX 580 is GCN 4th gen:
https://en.wikipedia.org/wiki/AMD_Radeon_500_series

Which is the last generation before Vega, which in Wikipedia is marked 
as GCN 5th gen:
https://en.wikipedia.org/wiki/List_of_AMD_graphics_processing_units

So there is no other GPU left between them. There is also nothing else 
beyond Vega, which suggests that the only difference between drm-stable 
and drm-next is the additional support for the latest GPU - Vega. Or I 
am missing something?

Thanks
