1TODO: 2 - checkpatch.pl cleanups 3 - sparse fixes 4 - rename files to be not so "generic" 5 - add proper arch dependencies as needed 6 - audit userspace interfaces to make sure they are sane 7 8 9ion/ 10 - Remove ION_IOC_SYNC: Flushing for devices should be purely a kernel internal 11 interface on top of dma-buf. flush_for_device needs to be added to dma-buf 12 first. 13 - Remove ION_IOC_CUSTOM: Atm used for cache flushing for cpu access in some 14 vendor trees. Should be replaced with an ioctl on the dma-buf to expose the 15 begin/end_cpu_access hooks to userspace. 16 - Clarify the tricks ion plays with explicitly managing coherency behind the 17 dma api's back (this is absolutely needed for high-perf gpu drivers): Add an 18 explicit coherency management mode to flush_for_device to be used by drivers 19 which want to manage caches themselves and which indicates whether cpu caches 20 need flushing. 21 - With those removed there's probably no use for ION_IOC_IMPORT anymore either 22 since ion would just be the central allocator for shared buffers. 23 - Add dt-binding to expose cma regions as ion heaps, with the rule that any 24 such cma regions must already be used by some device for dma. I.e. ion only 25 exposes existing cma regions and doesn't reserve unecessarily memory when 26 booting a system which doesn't use ion. 27 28Please send patches to Greg Kroah-Hartman <greg@kroah.com> and Cc: 29Arve Hj��nnev��g <arve@android.com> and Riley Andrews <riandrews@android.com> 30
