Remove anv_color_attachment_view and anv_depth_stencil_view, merging
them into anv_attachment_view. This prepares for merging
VkAttachmentView into VkImageView.
Rename all anv_*_view variables to follow this convention:
- sview -> anv_surface_view
- bview -> anv_buffer_view
- iview -> anv_image_view
- aview -> anv_attachment_view
- cview -> anv_color_attachment_view
- ds_view -> anv_depth_stencil_attachment_view
This clarifies existing code. And it will reduce noise in the upcoming
commits that merge VkAttachmentView into VkImageView.
Stencil buffers have strange pitch. The PRM says:
The pitch must be set to 2x the value computed based on width,
as the stencil buffer is stored with two rows interleaved.
In anv_depth_stencil_view, replace the members
bo
depth_offset
depth_stride
depth_format
depth_qpitch
stencil_offset
stencil_stride
stencil_qpitch
with the single member
const struct anv_image *image
The removed members duplicated data in anv_image::depth_surface and
anv_image::stencil_surface.
The format of the view itself and of the view's image may differ.
Moreover, if the view's format has no depth aspect but the image's
format does, we must not program the depth buffer. Ditto for stencil.
With all the previous commits in place, we can now drop in support for
multiple platforms. First up is gen7 (Ivybridge).
