2011-01-24drm/i915,agp/intel: Do not clear stolen entriesChris Wilson1-0/+4
We can only utilize the stolen portion of the GTT if we are in sole charge of the hardware. This is only true if using GEM and KMS, otherwise VESA continues to access stolen memory.

2011-01-11drm/i915/gtt: Unmap the PCI pages after unbinding them from the GTTChris Wilson1-7/+3
Dave Airlie spotted that his ILK laptop with DMAR enabled was generating the occasional DMAR warning. "The ordering in the previous code was to rewrite the GTT table before unmapping the pages and that makes sense to me." This is his stable patch ported to d-i-n.

Required for my pineview system to not barf after resuming. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2010-11-23drm/i915: Use drm_i915_gem_object as the preferred typeChris Wilson1-36/+32
A glorified s/obj_priv/obj/ with a net reduction of over a 100 lines and many characters! Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2010-11-23drm/i915: move gtt handling to i915_gem_gtt.cDaniel Vetter1-0/+28
No more drm_*_agp in i915_gem.c! Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2010-11-23drm/i915: restore gtt on resume in the drm instead of in intel-gtt.koDaniel Vetter1-0/+49
This still uses the agp functions to actually reinstate the mappings (with a gross hack to make agp cooperate), but it wires everything up correctly for the switchover. The call to agp_rebind_memory can be dropped because all non-kms drivers do all their rebinding on EnterVT. v2: Be more paranoid and flush the chipset cache after restoring gtt mappings.
