Subject: i965: Hook up the MCS buffers in SURFACE_STATE on Broadwell.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a248b2a4ebb27832d6c8a40ce2b10134f8735b93;p=mesa.git

i965: Hook up the MCS buffers in SURFACE_STATE on Broadwell.

MCS buffers are never allocated on Broadwell, so this does nothing for
now, but puts the infrastructure in place for when they do exist.
