A special buffer type for usage as the source for buffer to image copies with lower alignment requirements than A6XX_TEX_2D, available since A7XX. Allow early z-test and early-lrz (if applicable) Disable early z-test and early-lrz test (if applicable) A special mode that allows early-lrz (if applicable) or early-z tests, but also does late-z tests at which point it writes depth. This mode is used when fragment can be killed (via discard or sample mask) after early-z tests and it writes depth. In such case depth can be written only at late-z stage, but it's ok to use early-z to discard fragments. However this mode is not compatible with: - Lack of D/S attachment - Stencil writes on stencil or depth test failures - Per-sample shading Not a real hw value, used internally by mesa
