  16           Binder is used in Android for both communication between processes,
  17           and remote method invocation.
  18
  19           This means one Android process can call a method/routine in another
  20           Android process, using Binder to identify, invoke and pass arguments
  21           between said processes.

  28           Binderfs is a pseudo-filesystem for the Android Binder IPC driver
  29           which can be mounted per-ipc namespace allowing to run multiple
  30           instances of Android.
  31           Each binderfs mount initially only contains a binder-control device.
  32           It can be used to dynamically allocate new binder IPC devices via
  33           ioctls.

  40           Default value for the binder.devices parameter.
  41
  42           The binder.devices parameter is a comma-separated list of strings
  43           that specifies the names of the binder device nodes that will be
  44           created. Each binder device has its own context manager, and is
  45           therefore logically separated from the other devices.

  50         ---help---
  51           This feature allows binder selftest to run.
  52
  53           Binder selftest checks the allocation and free of binder buffers
  54           exhaustively with combinations of various buffer sizes and
  55           alignments.
