  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           Default value for the binder.devices parameter.
  29
  30           The binder.devices parameter is a comma-separated list of strings
  31           that specifies the names of the binder device nodes that will be
  32           created. Each binder device has its own context manager, and is
  33           therefore logically separated from the other devices.

  39         ---help---
  40           The Binder API has been changed to support both 32 and 64bit
  41           applications in a mixed environment.
  42
  43           Enable this to support an old 32-bit Android user-space (v4.4 and
  44           earlier).
  45
  46           Note that enabling this will break newer Android user-space.

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