From f3739810e337d0f03514b9b967594c8dc010dfa4 Mon Sep 17 00:00:00 2001 From: Chad Versace Date: Thu, 22 Dec 2016 14:39:44 -0800 Subject: [PATCH] mesa/texformat: Handle GL_RGBA + GL_UNSIGNED_SHORT_5_5_5_1 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit _mesa_choose_tex_format() already handles GL_RGBA + GL_UNSIGNED_SHORT_1_5_5_5_REV by converting it to MESA_FORMAT_B5G5R5A1_UNORM. Teach it do the same for the non-reversed type. Otherwise, the switch's fallthrough converts it to an 8888 format, which has incompatible precision in the alpha channel. Patch 2/2 to fix dEQP-EGL.functional.image.modify.tex_rgb5_a1_tex_subimage_rgba8 on Intel.
