From 1f96e9a98245b18c99cc6a7e66372a076b9abf6b Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Mon, 17 Mar 2008 07:05:46 +1000 Subject: drm/pcigart: fix the pci gart to use the drm_pci wrapper. This is the correct fix for the RS690 and hopefully the dma coherent work. For now we limit everybody to a 32-bit DMA mask but it is possible for RS690 to use a 40-bit DMA mask for the GART table itself, and the PCIE cards can use 40-bits for the table entries.
