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
