From 8adf813f83b9f54e3c9958cc7c7a485e62222e2e Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Wed, 25 Apr 2018 11:40:40 -0700 Subject: st: Choose a 2101010 format for GL_RGB/GL_RGBA with a 2_10_10_10 type. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit GLES's GL_EXT_texture_type_2_10_10_10_REV allows uploading this type to an unsized internalformat, and it should be non-color-renderable. fbobject.c's implementation of the check for color-renderable is checks that the texture has a 2101010 mesa format, so make sure that we have chosen a 2101010 format so that check can do what it meant to. Fixes KHR-GLES3.packed_pixels.pbo_rectangle.rgb on vc5.
