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 28sync framework: 29 - remove CONFIG_SW_SYNC_USER, it is used only for testing/debugging and 30 should not be upstreamed. 31 - port CONFIG_SW_SYNC_USER tests interfaces to use debugfs somehow 32 - port libsync tests to kselftest 33 - clean up and ABI check for security issues 34 - move it to drivers/base/dma-buf 35 36vsoc.c, uapi/vsoc_shm.h 37 - The current driver uses the same wait queue for all of the futexes in a 38 region. This will cause false wakeups in regions with a large number of 39 waiting threads. We should eventually use multiple queues and select the 40 queue based on the region. 41 - Add debugfs support for examining the permissions of regions. 42 - Use ioremap_wc instead of ioremap_nocache. 43 - Remove VSOC_WAIT_FOR_INCOMING_INTERRUPT ioctl. This functionality has been 44 superseded by the futex and is there for legacy reasons. 45 46Please send patches to Greg Kroah-Hartman <greg@kroah.com> and Cc: 47Arve Hjønnevåg <arve@android.com> and Riley Andrews <riandrews@android.com> 48
