I agree. VK_IMAGE_ASPECT_DEPTH_BIT makes more sense.
Also, that's what the documentation for anv_image says, quoted below:
struct anv_image {
...
/**
* Image subsurfaces
*
* For each foo, anv_image::foo_surface is valid if and only if
* anv_image::aspects has a foo aspect.
*
* ...
*/
union {
struct anv_surface color_surface;
struct {
struct anv_surface depth_surface;
struct anv_surface stencil_surface;
};
};
};
