*
|
|
* Gfx12+ allows to set RENDER_SURFACE_STATE::SurfaceArray to 1 only if
|
|
* array_len > 1. Setting RENDER_SURFACE_STATE::SurfaceArray to 0 results in
|
|
* the HW RESINFO message to report an array size of 0 which breaks texture
|
|
* array size queries.
|
|
*
|
|
* This NIR pass works around this by patching the array size with a
|
|
* MAX(array_size, 1) for array textures.
