Subject: intel: Make the intel_miptree_match_image format check more specific.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0fac09a87c07d09dcd915c02b831505a53b02153;p=mesa.git

intel: Make the intel_miptree_match_image format check more specific.

We don't care just about the internalFormat/cpp/compressed, but about
the specific format chosen.  We have no support for format
translations as part of texture validation, and furthermore it has
restrictions in the GL specification.  However, we should be making
consistent decisions for this check anyway.
