For an upcoming patch where we introduce the i915 VMA, it's ideal to have the drm_mm_node as part of the VMA struct (ie. it's pre-allocated). Part of the conversion to VMAs is to kill off obj->gtt_space. Doing this will break a bunch of code, but amongst them are 2 callers of drm_mm_create_block(), both related to stolen memory. It also allows us to embed the drm_mm_node into the object currently which provides a nice transition over to the new code. v2: Reordered to do before ripping out obj->gtt_offset. Some minor cleanups made available because of reordering. v3: s/continue/break on failed stolen node allocation (David) Set obj->gtt_space on failed node allocation (David) Only unref stolen (fix double free) on failed create_stolen (David) Free node, and NULL it in failed create_stolen (David) Add back accidentally removed newline (David) CC: <dri-devel@lists.freedesktop.org> Reviewed-by: David Herrmann <dh.herrmann@gmail.com> Signed-off-by: Ben Widawsky <ben@bwidawsk.net> Acked-by: David Airlie <airlied@linux.ie> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> |

************************************************************
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
http://sourceforge.net/project/showfiles.php?group_id=387
http://dri.sourceforge.net/doc/
