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) Please send patches to Greg Kroah-Hartman <greg@xxxxxxxxx> and Cc: Arve Hjønnevåg <arve@xxxxxxxxxxx> and Riley Andrews <riandrews@xxxxxxxxxxx> -- 2.7.4
