There has been a lot of interesting, sometimes seemingly-conflicting things happening in the UMM world in the recent past. This includes a bunch of sessions at the recently concluded Linux Plumbers' Conference. This session aims at discussing the directions going forward on some of those:
- fences - dma-buf fences v/s Android sync driver.
- Ways to make ION-like functionality available upstream - constraint-solving for dma-buf, etc
- Other updates
