radv: Implement ray-tracing for older generations (!12974) · Merge requests · Mesa / mesa · GitLab

Joshua Ashton requested to merge frog/mesa:radv-vega-rt-pullrequest into main Sep 22, 2021

This PR implements ray-tracing for older generations (Navi, Vega, Polaris, etc.)

It does this by emulating the AMD bvh intersection instructions in software.

Right now this passes CTS the same as on RDNA 2 cards.
