Konstantin Seurer	d140f2a6a2	radv: Implement watertightness for emulated RT ... Instead of using fp64 (Which is broken in some cases) the new approach only uses fp32 and implements tiebreaking for edge/vertex hits. Using fp32 is also much faster, improving performance of q2rtx by around 40%.

Konstantin Seurer	df44b353ad	radv: Optimize ray tracing position fetch ... Gets rid of a lot of indirection when fetching triangle positions. Storing the primitive address increases register pressure by a bit but the traversal shader which should have the highest register demand should not be affected when position fetch is not used.

Ivan Avdeev	14e3231b56	radv: add a flag to indicate ray tracing support ... Determine whether the device has hardware raytracing support early, and then use this result where needed, instead of checking for `gfx_level` every time. This is a prerequisite for CYAN_SKILLFISH chip enablement. This chip is still GFX10, not GFX10_3, but has hardware support for accelerated `image_bvh{,64}_intersect_ray` instructions. Just checking for `gfx_level` is insufficient for it. Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/33109>	2025-01-20 08:27:11 +00:00
Arseny Kapoulkine	6a3944a195	radv: On GFX11, use box sorting heuristic based on ray flags ... Use box with largest ray interval for shadow rays (terminate on first hit) as it maximizes the probability of finding some object in that box; for reflection (closest hit) rays, use midpoint instead, which defers processing of larger boxes the ray origin is in in favor of smaller boxes closer to origin. Since the sorting mode must be uniform, when terminate_on_first_hit flag is divergent, we leave it as closest.
