From b397c836eff58cd9a43f7bd8b853a51b3ecc3420 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Tue, 26 Jan 2010 09:43:10 -0800 Subject: [PATCH] drm/i915: Don't reserve compatibility fence regs in KMS mode. The fence start is for compatibility with UMS X Servers before fence management. KMS X Servers only started doing tiling after fence management appeared.
