Hi all,
This patch-set changes the algorithm in drm_mm.c to not need additional
allocations to track free space and adds an api to make embedding struct
drm_mm_node possible. Benefits:
- If struct drm_mm_node is provided, no allocations need to be done anymore
in drm_mm. It looks like some decent surgery, but ttm should be able to
drop its preallocation dance.
- void *priv is back, but done right ;)
- Avoids a pointer chase when lru-scanning in i915 and saves a few bytes.
As a proof of concept I've converted i915. Beware though, the drm/i915
patches depend on my direct-gtt patches (which are actually the reason for
this series here).
Tested on my i855gm, i945gme, ironlake and agp rv570.
Comments, flames, reviews highly welcome.
