ion/
- - Remove ION_IOC_SYNC: Flushing for devices should be purely a kernel internal
- interface on top of dma-buf. flush_for_device needs to be added to dma-buf
- first.
- - Remove ION_IOC_CUSTOM: Atm used for cache flushing for cpu access in some
- vendor trees. Should be replaced with an ioctl on the dma-buf to expose the
- begin/end_cpu_access hooks to userspace.
- - Clarify the tricks ion plays with explicitly managing coherency behind the
- dma api's back (this is absolutely needed for high-perf gpu drivers): Add an
- explicit coherency management mode to flush_for_device to be used by drivers
- which want to manage caches themselves and which indicates whether cpu caches
- need flushing.
- - With those removed there's probably no use for ION_IOC_IMPORT anymore either
- since ion would just be the central allocator for shared buffers.
- - Add dt-binding to expose cma regions as ion heaps, with the rule that any
- such cma regions must already be used by some device for dma. I.e. ion only
- exposes existing cma regions and doesn't reserve unecessarily memory when
- booting a system which doesn't use ion.
+ - Add dt-bindings for remaining heaps (chunk and carveout heaps). This would
+ involve putting appropriate bindings in a memory node for Ion to find.
+ - Split /dev/ion up into multiple nodes (e.g. /dev/ion/heap0)
+ - Better test framework (integration with VGEM was suggested)
