Thomas Hellstrom e1efc9b6ac drm/ttm: Optimize delayed buffer destruction This commit replaces the ttm_bo_cleanup_ref function with two new functions. One for the case where the bo is not yet on the delayed destroy list, and one for the case where the bo was on the delayed destroy list, at least at the time of call. This makes it possible to optimize the two cases somewhat. It also enables the possibility to directly destroy buffers on the delayed delete list when they are about to be evicted or swapped out. Currently they were only evicted / swapped and destruction was left for the delayed buffer destruction thread.

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:
