Jesse Barnes d4270e57ef drm/i915: export a CPT mode set verification function 
At the point where we check, we can't do much about the failure, but it
can aid debugging.  Note that the auto-train override bit will be reset
as part of normal mode setting with this patch if a pipe ever does get
stuck, but that's consistent with the workaround for CPT provided by the
hardware team.  This patch helped catch the fact that the pipe wasn't
running in the !composite sync FDI case on my IVB SDV, so has already
shown to be useful.

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:
