As soon as Bas Nieuwenhuizen mentioned that he was working on support for Vulkan Raytracing in RADV, my curiosity as to whether this feature could be brought to older generations of AMD hardware was peaked.

Yesteryesterday and yesterday I decided to implement some of the missing pieces for exposing Vulkan Raytracing on older generations of AMD hardware, such as Vega, Polaris and the original Navi.

The work is currently available here if you wish to try it at your own risk.
