staging: ion: remove from the tree

2020-10-26T05:53:09+00:00

The ION android code has long been marked to be removed, now that we dma-buf support merged into the real part of the kernel. It was thought that we could wait to remove the ion kernel at a later time, but as the out-of-tree Android fork of the ion code has diverged quite a bit, and any Android device using the ion interface uses that forked version and not this in-tree version, the in-tree copy of the code is abandonded and not used by anyone. Combine this abandoned codebase with the need to make changes to it in order to keep the kernel building properly, which then causes merge issues when merging those changes into the out-of-tree Android code, and you end up with two different groups of people (the in-kernel-tree developers, and the Android kernel developers) who are both annoyed at the current situation. Because of this problem, just drop the in-kernel copy of the ion code now, as it's not used, and is only causing problems for everyone involved.

selftests/android: initialize heap_type to avoid compiling warning

2018-07-11T16:13:17+00:00

Initialize heap_type to ION_HEAP_TYPE_SYSTEM to avoid "used uninitialized" compiler warning. heap_type gets used after initialization, this change is to just keep the compiler happy. root@vm-lkp-nex04-8G-7 ~/linux-v4.18-rc2/tools/testing/selftests/android# make make[1]: warning: jobserver unavailable: using -j1.

android/ion: userspace test utility for ion buffer sharing

2017-11-15T15:07:53+00:00

This is a test utility to verify ION buffer sharing in user space between 2 independent processes. It uses unix domain socket (with SCM_RIGHTS) as IPC to transfer an FD to another process to share the same buffer. This utility demonstrates how ION buffer sharing can be implemented between two user space processes, using various heap types. This utility is made to be run as part of kselftest framework in kernel. The utility is verified on Ubuntu-32 bit system with Linux Kernel 4.14, using ION system heap. For more information about the utility please check the README file. Signed-off-by: Pintu Agarwal Signed-off-by: Shuah Khan
