From ffb57c4b8612c31204b06713770f6df4b8a94e4f Mon Sep 17 00:00:00 2001 From: Jay Estabrook Date: Wed, 6 Jul 2011 23:57:13 +0000 Subject: drm/radeon/alpha: Add Alpha support to Radeon DRM code Alpha needs to have available the system bus address for the Radeon's local memory, so that it can be used in ttm_bo_vm_fault(), when building the PTEs for accessing that VRAM. So, we make bus.addr hold the ioremap() return, and then we can modify bus.base appropriately for use during page fault processing.
