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