Dave Airlie 218c872bf8 Merge tag 'drm-intel-next-2012-05-06-merged' of git://people.freedesktop.org/~danvet/drm-intel into drm-core-next
Daniel says

Highlights:
- sparse fixes from Ben.
- tons of little cleanups from Chris all over: tiling_changed
 clarification, deferred_free list removal, ...
- fix up irq handler on gen2 & gen3 + related cleanups from Chris
- prep work for wait_rendering_timeout from Ben with some nice
 refactorings
- first set of infoframe fixes from Paulo for doubleclocked CEA modes
- improve pch pll handling from Jesse and Chris
- gpu hangman, this also contains the reset fix for gen4
- rps sanity check from Chris - this papers over issues when the gpu fails
 to clock up on snb/ivb, and it is shockingly easy to hit. The code
 prints a big WARN backtrace and restores the hw to a sane state. The
 real fix is still in the works.

Atm I'm aware of 2 regressions in -next:
- One of the gmbus patches (not gmbus itself) regressed lvds detection on
 a MacbookPro. I've analyzed the bug already and I think I know what's
 going on, patch is awaiting test feedback.
- Just today QA reported that DP on ilk regressed. That bug is fresh of
 the press and still awaiting detailed logfiles and the bisect result.
 The only thing that's clear atm is that -fixes works and -next doesn't.

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:
    http://dri.freedesktop.org/wiki/Documentation
