   Is VK_KHR_ray_tracing_pipeline supposed to work in #amdgpu in Mesa 23?

   On the RX 9700 XT, it hangs the GPU. The kernel reports dozens of "[gfxhub] page fault" from the rendering process. I tried with kernel 6.1 and drm-tip.

   I'm testing with this demo:

     Ah! finally got it to work! I just had to *downgrade* mesa to 22.3 and set RADV_PERFTEST=rt to enable VK_KHR_ray_tracing_pipeline.
