This patch updates the blorp engine to properly handle the case where
the surface being textured from uses Gen7's CMS MSAA layout. The
following changes were necessary:
- Before reading color values from the surface, we need to read from
the MCS buffer using the ld_mcs sampler message. This is

When a buffer using Gen7's CMS MSAA layout is bound to a texture or a
render target, the SURFACE_STATE structure needs to point to the MCS
buffer and to indicate its pitch. This patch updates the functions
that emit SURFACE_STATE to handle CMS layout properly.

Previously the DWORD used to control the CMS MSAA layout was just a
pad value, because we didn't use it.

To implement Gen7's CMS MSAA layout, we need an extra buffer, the MCS
(Multisample Control Surface) buffer. This patch introduces code for
allocating and deallocating the buffer, and storing a pointer to it in
the intel_mipmap_tree struct.
No functional change, since the CMS layout is not enabled
>From the Ivy Bridge PRM, Vol 1 Part 1, p112:
There are three types of multisampled surface layouts designated
as follows:
- IMS Interleaved Multisampled Surface
- CMS Compressed Mulitsampled Surface
- UMS Uncompressed Multisampled Surface
Previously, the i965 driver onl
On Gen6, MSAA buffers always use an interleaved layout and non-MSAA
buffers always use a non-interleaved layout, so it is not strictly
necessary to keep track of the layout of the texture and render target
surfaces in the blorp program key. However, it is cleaner to do so,
since (a) it makes the b
This patch series adds support for the "Compressed Multisample
Surface" layout, which should speed up multisample rendering on Gen7
by decreasing memory bandwidth requirements.
Patches 1-2 do preparatory refactoring, including creating a function
to determine which MSAA layout should be used based

While I've not some questions about the other patches, this one is:
