From 7907f45bf9f67a1c5e5d4ae05bab428d7c2f43b2 Mon Sep 17 00:00:00 2001 From: Ben Widawsky Date: Wed, 19 Feb 2014 22:05:46 -0800 Subject: [PATCH] Revert "drm/i915/bdw: Limit GTT to 2GB" This reverts commit 3a2ffb65eec6dbda2fd8151894f51c18b42c8d41. Now that the code is fixed to use smaller allocations, it should be safe to let the full GGTT be used on BDW. The testcase for this is anything which uses more than half of the GTT, thus eclipsing the old limit.
