X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=81b036b4d79423c194596461b098a525af0102c2;p=mesa.git i965/gen5+: Fix incorrect miptree layout for non-power-of-two cubemaps. For power-of-two sizes, h0 == mt->height0 since it's already a multiple of two. However, for NPOT, they're different; h1 should be computed based on the original size. Fixes piglit test "cubemap npot" and oglconform test "textureNPOT". NOTE: This is a candidate for stable release branches.
