4 - DT bindings (Neil, WIP)
5 - MMU page table format and address space setup
6 - Bifrost specific feature and issue handling
9 - Support for 2MB pages. The io-pgtable code already supports this. Finishing
10 support involves either copying or adapting the iommu API to handle passing
11 aligned addresses and sizes to the io-pgtable code.
13 - Per FD address space support. The h/w supports multiple addresses spaces.
14 The hard part is handling when more address spaces are needed than what
17 - Support pinning pages on demand (GPU page faults).
19 - Support userspace controlled GPU virtual addresses. Needed for Vulkan. (Tomeu)
21 - Support for madvise and a shrinker.
23 - Compute job support. So called 'compute only' jobs need to be plumbed up to
26 - Performance counter support. (Boris)
