From 1a029b768f9d4a001501bd18d6ba08297ae912fd Mon Sep 17 00:00:00 2001 From: Jerome Glisse Date: Tue, 6 Oct 2009 19:04:30 +0200 Subject: drm/radeon/kms: Fix AGP support for R600/RV770 family (v2) For AGP to work unmapped access must cover VRAM & AGP as AGP is treated like VRAM by the GPU (ie physical address). This patch properly setup the virtual memory system aperture to cover AGP if AGP is enabled. It seems that there is memory corruption after resume when using AGP (RV770 seems unaffected thought). Version 2 just fix merge issue with updated AGP fallback patch.
