0009 Binder is used in Android for both communication between processes,
0010 and remote method invocation.
0011
0012 This means one Android process can call a method/routine in another
0013 Android process, using Binder to identify, invoke and pass arguments
0014 between said processes.

0021 Binderfs is a pseudo-filesystem for the Android Binder IPC driver
0022 which can be mounted per-ipc namespace allowing to run multiple
0023 instances of Android.
0024 Each binderfs mount initially only contains a binder-control device.
0025 It can be used to dynamically allocate new binder IPC devices via
0026 ioctls.

0033 Default value for the binder.devices parameter.
0034
0035 The binder.devices parameter is a comma-separated list of strings
0036 that specifies the names of the binder device nodes that will be
0037 created. Each binder device has its own context manager, and is
0038 therefore logically separated from the other devices.

0044 This feature allows binder selftest to run.

0046 Binder selftest checks the allocation and free of binder buffers
0047 exhaustively with combinations of various buffer sizes and
0048 alignments.
