2017-10-19drm/amdgpu: allow GTT overcommit during bindChristian König
While binding BOs to GART we need to allow a bit overcommit in the GTT domain. Otherwise we can never use the full GART space when GART size=GTT size.

2017-02-03drm: Improve drm_mm search (and fix topdown allocation) with rbtreesChris Wilson
The drm_mm range manager claimed to support top-down insertion, but it was neither searching for the top-most hole that could fit the allocation request nor fitting the request to the hole correctly. In order to search the range efficiently, we create a secondary index for the holes using either their size or their address. This index allows us to find the smallest hole or the hole at the bottom or top of the range efficiently, whilst keeping the hole stack to rapidly service evictions. v2: Search for holes both high and low. Rename flags to mode. v3: Discover rb_entry_safe() and use it! v4: Kerneldoc for enum drm_mm_insert_mode.

2016-12-30drm/mm: Convert to drm_printerDaniel Vetter
