X-Git-Url: https://git.libre-soc.org/?p=mesa.git;a=commitdiff_plain;h=befbda56a246f77797bdf13fc005353441db2879 i965: Validate (and resolve) all the bound textures. BRW_MAX_TEX_UNIT is the static limit on the number of textures we support per-stage, not in total. Core's `Unit` array is sized by MAX_COMBINED_TEXTURE_IMAGE_UNITS, which is significantly larger, and across the various shader stages, up to ctx->Const.MaxCombinedTextureImageUnits elements of it may be actually used. Fixes invisible bad behavior in piglit's max-samplers test (although this escalated to an assertion failure on HSW with texture_view, since non-immutable textures only have _Format set by validation.)
