The patchset implements per-heap devices which can be opened directly and then an ioctl is used to allocate a dmabuf from the heap. The interface is similar, but much simpler then IONs, only providing an ALLOC ioctl. Also, I've provided relatively simple system and cma heaps. I've booted and tested these patches with AOSP on the HiKey960 using the kernel tree here: https://git.linaro.org/people/john.stultz/android-dev.git/log/?h=dev/dma-buf-heap And the userspace changes here: https://android-review.googlesource.com/c/device/linaro/hikey/+/909436 Compared to ION, this patchset is missing the system-contig, carveout and chunk heaps, as I don't have a device that uses those, so I'm unable to do much useful validation there. Additionally we have no upstream users of chunk or carveout, and the system-contig has been deprecated in the common/andoid-* kernels, so this should be ok. I've also removed the stats accounting, since any such accounting should be implemented by dma-buf core or the heaps themselves.
