From 6196259d957cc7c3ea355b74649623ef7e582854 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Mon, 1 Jul 2019 12:39:55 -0700 Subject: [PATCH] gallium: Add defines for FXT1 texture compression. MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This texture compression is exposed by 830 and 915, and to make MESA_FORMAT match PIPE_FORMAT defines I need a corresponding PIPE_FORMAT. v2: Set is_hand_written so we don't try to generate pack/unpack code.
