staging: android: ion: Fix license identifier comment format

2018-05-08T11:34:39Z

checkpatch.pl complains these are invalid because the rules in Documentation/process/license-rules.rst state that C headers should have "/* */" style comments. Signed-off-by: Nathan Chancellor Acked-by: Laura Abbott Signed-off-by: Greg Kroah-Hartman

staging: android: Clean up license identifiers

2018-05-08T11:24:15Z

Add the identifiers when missing and fix the ones already present according to checkpatch.pl. Signed-off-by: Nathan Chancellor Signed-off-by: Greg Kroah-Hartman

staging: Android: Add 'vsoc' driver for cuttlefish.

2018-04-23T12:51:37Z

The cuttlefish system is a virtual SoC architecture based on QEMU. It uses the QEMU ivshmem feature to share memory regions between guest and host with a custom protocol.

staging: android: Remove redundant license text

2017-11-28T12:20:48Z

Now that the SPDX tag is in all android files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording can be removed as it is no longer needed at all. This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed. No copyright headers or other non-license-description text was removed.

staging: android: add SPDX identifiers to all android driver files

2017-11-28T12:20:47Z

It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the android driver files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

staging: android: ion: Remove ion_handle and ion_client

2017-04-18T18:43:14Z

ion_handle was introduced as an abstraction to represent a reference to a buffer via an ion_client. As frameworks outside of Ion evolved, the dmabuf emerged as the preferred standard for use in the kernel. This has made the ion_handle an unnecessary abstraction and prone to race conditions. ion_client is also now only used internally. We have enough mechanisms for race conditions and leaks already so just drop ion_handle and ion_client. This also includes ripping out most of the debugfs infrastructure since much of that was tied to clients and handles. The debugfs infrastructure was prone to give confusing data (orphaned allocations) so it can be replaced with something better if people actually want it.

staging: android: ion: Break the ABI in the name of forward progress

2017-04-18T18:43:14Z

Several of the Ion ioctls were designed in such a way that they necessitate compat ioctls. We're breaking a bunch of other ABIs and cleaning stuff up anyway so let's follow the ioctl guidelines and clean things up while everyone is busy converting things over anyway. As part of this, also remove the useless alignment field from the allocation structure. Signed-off-by: Laura Abbott Signed-off-by: Greg Kroah-Hartman

staging: android: ion: Remove old platform support

2017-04-08T10:36:11Z

Device specific platform support has been haphazard for Ion. There have been several independent attempts and there are still objections to what bindings exist right now. Just remove everything for a fresh start. Signed-off-by: Laura Abbott Signed-off-by: Greg Kroah-Hartman
