From 922c0c9fd526ce19b87bc74a3159dec7705c1de1 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Fri, 5 Jun 2015 14:45:18 +0100 Subject: [PATCH] i965: Export format comparison for blitting between miptrees MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Since the introduction of commit 536003c11e4cb1172c540932ce3cce06f03bf44e Author: Boyan Ding Date: Wed Mar 25 19:36:54 2015 +0800 i965: Add XRGB8888 format to intel_screen_make_configs winsys buffers no longer have an alpha channel. This causes _mesa_format_matches_format_and_type() to reject previously working BGRA uploads from using the BLT fast path. Instead of using the generic routine for matching formats exactly, export the slightly more relaxed check from intel_miptree_blit() which importantly allows the blitter routine to apply a small number of format conversions.
