From 1ab2e1059916b917af19e4137a4222988bd7a169 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Michel=20D=C3=A4nzer?= Date: Tue, 28 Jul 2009 12:30:56 +0200 Subject: [PATCH] drm/radeon: Fall back to evicting BOs with memcpy if necessary. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Otherwise if there's no GTT space we would fail the eviction, leading to cascaded failure.
