- add proper arch dependencies as needed
- audit userspace interfaces to make sure they are sane
+
+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.
