Daniel Vetter 25853a12e4 drm/mm: fix dump table BUG commit `3a359f0b21` upstream. In commit `9e8944ab56` Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Thu Nov 15 11:32:17 2012 +0000 drm: Introduce an iterator over holes in the drm_mm range manager helpers and iterators for hole handling have been introduced with some debug BUG_ONs sprinkled over. Unfortunately this broke the mm dumper which unconditionally tried to compute the size of the very first hole. While at it unify the code a bit with the hole dumping in the loop. v2: Extract a hole dump helper.

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
