From 54aec44ab02b1fa216706671ae12d64af74443c5 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Mon, 25 Jan 2016 13:52:41 -0800 Subject: [PATCH] drm/vc4: Fix the clear color for the first tile rendered. Apparently in hardware (as opposed to simulation), the clear colors need to be uploaded before the render config, otherwise they won't take effect. Fixes igt's vc4_wait_bo/used-bo-* subtests.
