The amdgpu driver, equivalent to Linux 4.19, has been committed along with supporting changes in ttm. Credit goes to Sergey Zigachev, Francois Tigeot, and Matthew Dillon for the work. The module is now built by default in bleeding edge DragonFly. Note the amdgpu commit message lists some options that need to be set.

Does this have any support for ROCm?
I have seen no mention of it. ROCm sounds like an application suite, not a hardware driver exactly, so very different.
Does this means my Radeon Vega 64 would now work with DragonFly? After I ditched my Radeon HD69xx card and bought Vega, I haven’t been able to use it with DragonFly.
I think so, going by the list here:

But the only way to be sure is to try.
