4 - For discrete memory manager, merge enough dg1 to be able to refactor it to
8 - Come up with a plan what to do with drm/scheduler and how to get there.
10 - Roll out dma_fence critical section annotations.
12 - There's a lot of complexity added past few years to make relocations faster.
15 1. Land a modern pre-bound uapi like VM_BIND
19 refcounts, caching, ... on everything.
23 - i915_sw_fence seems to be the main structure for the i915-gem dma_fence model.
24 How-to-dma_fence is core and drivers really shouldn't build their own world
