Chris Wilson 2ebed176a7 drm/i915: Set framebuffer alignment based upon the fence constraints. 
Set the request alignment to 0, and leave it up to i915_gem_object_pin()
to set the appropriate alignment to match the fence covering the object.

Eric Anholt mentioned that the pinning code is meant to choose the
maximum of the request alignment and that of the fence covering the
object... However currently, the pinning code will only apply the fence
constraints if the supplied alignment is 0.

The Direct Rendering Manager (drm) is a device-independent kernel-level
device driver that provides support for the XFree86 Direct Rendering
Infrastructure (DRI).

The DRM supports the Direct Rendering Infrastructure (DRI) in four major
ways:

    1. The DRM provides synchronized access to the graphics hardware via
       the use of an optimized two-tiered lock.

    2. The DRM enforces the DRI security policy for access to the graphics
       hardware by only allowing authenticated X11 clients access to
       restricted regions of memory.

    3. The DRM provides a generic DMA engine, complete with multiple
       queues and the ability to detect the need for an OpenGL context
       switch.

    4. The DRM is extensible via the use of small device-specific modules
       that rely extensively on the API exported by the DRM module.


Documentation on the DRI is available from:
