Subject: Replace usage of DRM_BO_FLAG_MEM_TT in intel_regions.c with local/cached.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=fd776e10b327b6a49b76c5082e4cc48059c6ad2e;p=mesa.git

Replace usage of DRM_BO_FLAG_MEM_TT in intel_regions.c with local/cached.

In addition to potentially binding when it was about to be mapped anyway,
failure to use CACHED_MAPPED means eating a full wbinvd on validate.  Thanks to
airlied for catching this.
