X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=79d981cd03f2e2e8f67ab21d52711de989bb9a44;p=mesa.git i965: Don't minify depth when setting up cube map miptrees on Gen4. Prior to Ironlake, cube maps were stored as 3D textures. In recent refactoring, we removed a separate "layers" parameter in favor of using depth. Unfortunately, depth was getting minified, which is only correct for actual 3D textures. Fixes piglit tests: - bugs/crash-cubemap-order - fbo/fbo-cubemap - texturing/cubemap Also changes texturing/cubemap npot from abort to fail. This hasn't seen a full test run since Piglit on Mesa master hangs GM45 a lot.
