From 595dad76a0d213adc3dbe4f463f7887e905082b9 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Thu, 13 Jan 2011 11:03:48 +0000 Subject: [PATCH] drm/i915/execbuffer: Clear domains before beginning reloc processing After reordering the sequence of relocating objects, commit 6fe4f1404, we can no longer rely on seeing all reloc targets prior to performing the relocation. As a result we were ignoring the need to flush objects from the render cache and invalidate the sampler caches, resulting in rendering glitches. So we need to clear the relocation domains earlier.
