Author: Samuel Pitoiset <samuel.pitoi...@gmail.com> Date: Fri Nov 17 16:40:56 2023 +0100 ac/surface: change tile mode for 3D PRT surfaces with bpp < 64 on GFX6-8 This is loosely based on PAL. This seems to fix 3D PRT support with RADV on Polaris10. THIN means the tile is a 2D slice. THICK means the tile is a 3D box.
