From 52ea0718ea506df0915eacedb439e65c5f214e0e Mon Sep 17 00:00:00 2001 From: Wang Zhenyu Date: Tue, 10 Apr 2007 09:42:48 +0800 Subject: [AGPGART] intel_agp: fix G965 GTT size detect On G965, I810_PGETBL_CTL is a mmio offset, but we wrongly take it as pci config space offset in detecting GTT size. This one line patch fixs this.
