The drm/ttm patch modifies TTM to support multiple contexts for the pipelined moves.
Then amdgpu/ttm is updated to express dependencies between jobs explicitely, instead of relying on the ordering of execution guaranteed by the use of a single instance. With all of this in place, we can use multiple entities, with each having access to the available SDMA instances.
This rework also gives the opportunity to merge the clear functions into a single one and to optimize a bit GART usage.
(The first patch of the series has already been merged through drm-misc but I'm including it here to reduce conflicts)
