Tiled buffers have the same alignment requirements regardless of whether the surface is for db, cb, or textures.

2010-11-13drm/i915: Retire any pending operations on the old scanout when switchingChris Wilson
An old and oft reported bug, is that of the GPU hanging on a MI_WAIT_FOR_EVENT following a mode switch. The cause is that the GPU is waiting on a scanline counter on an inactive pipe, and so waits for a very long time until eventually the user reboots his machine. We can prevent this either by moving the WAIT into the kernel and thereby incurring considerable cost on every swapbuffers, or by waiting for the GPU to retire the last batch that accesses the framebuffer before installing a new one. As mode switches are much rarer than swap buffers, this looks like an easy choice.

2010-11-11drm/i915: Remove the definitions for Primary Ring BufferChris Wilson
We only ever used the PRB0, neglecting the secondary ring buffers, and now with the advent of multiple engines with separate ring buffers we need to excise the anachronisms from our code (and be explicit about which ring we mean where). This is doubly important in light of the FORCEWAKE required to read ring buffer registers on SandyBridge. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2010-11-09DRM: ignore invalid EDID extensionsSam Tygier
Currently an invalid EDID extension will cause the whole EDID to be considered invalid. Instead just drop the invalid extensions, and return the valid ones.
