2012-04-02drm/i915: disable ppgtt on snb when dmar is enabledDaniel Vetter1-0/+4
Totally unexpected that this regressed. Luckily it sounds like we just need to have dmar disable on the igfx, not the entire system. At least that's what a few days of testing between Tony Vroon and me indicates.

2012-02-09agp/intel-gtt: export the gtt pagetable iomappingDaniel Vetter1-0/+2
We need this because ppgtt page directory entries need to be in the global gtt pagetable.

2012-02-09agp/intel-gtt: export the scratch page dma addressDaniel Vetter1-0/+2
To implement a PPGTT for drm/i915 that fully aliases the GTT, we also need to properly alias the scratch page.

2011-10-20drm/i915: ILK + VT-d workaroundBen Widawsky1-0/+2
Idle the GPU before doing any unmaps. We know if VT-d is in use through an exported variable from iommu code. This should avoid a known HW issue. Signed-off-by: Ben Widawsky <ben@bwidawsk.net> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Keith Packard <keithp@keithp.com>

2010-09-08drm/i915: die, i915_probe_agp, dieDaniel Vetter1-0/+2
Use the detection from intel-gtt.ko instead. Hooray! Also move the stolen mem allocator to the other gtt stuff in dev_prv->mem. v2: Chris Wilson noted that my error handling was crap. Fix it. He also said that this fixes a problem on his i845. Indeed, i915_probe_agp misses a special case for i830/i845 stolen mem detection.

Add a few definitions to it that are already shared and that will be shared in the future (like the number of stolen entries). No functional changes in here. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
