+- 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)
