drm/i915: call intel_enable_gtt

2012-06-12T20:21:07+00:00

When drm/i915 is in control of the gtt, we need to call the enable function at all the relevant places ourselves. Reviewed-by: Jani Nikula Signed-off-by: Daniel Vetter

drm/i915 + agp/intel-gtt: prep work for direct setup

2012-06-12T20:19:49+00:00

To be able to directly set up the intel-gtt code from drm/i915 and avoid setting up the fake-agp driver we need to prepare a few things: - pass both the bridge and gpu pci_dev to the probe function and add code to handle the gpu pdev both being present (for drm/i915) and not present (fake agp). - add refcounting to the remove function so that unloading drm/i915 doesn't kill the fake agp driver v2: Fix up the cleanup and refcount, noticed by Jani Nikula.

drm/i915: stop using dev->agp->base

2012-06-12T20:18:06+00:00

For that to work we need to export the base address of the gtt mmio window from intel-gtt. Also replace all other uses of dev->agp by values we already have at hand. Reviewed-by: Jani Nikula Signed-off-by: Daniel Vetter

drm/i915: disable ppgtt on snb when dmar is enabled

2012-04-02T13:59:07+00:00

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.

agp/intel-gtt: export the gtt pagetable iomapping

2012-02-09T20:24:18+00:00

We need this because ppgtt page directory entries need to be in the global gtt pagetable. Reviewed-by: Ben Widawsky Tested-by: Chris Wilson Tested-by: Eugeni Dodonov Reviewed-by: Eugeni Dodonov Signed-Off-by: Daniel Vetter

agp/intel-gtt: export the scratch page dma address

2012-02-09T20:23:18+00:00

To implement a PPGTT for drm/i915 that fully aliases the GTT, we also need to properly alias the scratch page. Reviewed-by: Ben Widawsky Tested-by: Chris Wilson Tested-by: Eugeni Dodonov Reviewed-by: Eugeni Dodonov Signed-Off-by: Daniel Vetter

drm/i915: ILK + VT-d workaround

2011-10-20T22:26:39+00:00

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 Reviewed-by: Daniel Vetter Signed-off-by: Keith Packard
