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

  22 config ANDROID_BINDER_DEVICES
  23         string "Android Binder devices"

  26         ---help---
  27           Default value for the binder.devices parameter.
  28
  29           The binder.devices parameter is a comma-separated list of strings
  30           that specifies the names of the binder device nodes that will be
  31           created. Each binder device has its own context manager, and is
  32           therefore logically separated from the other devices.

  34 config ANDROID_BINDER_IPC_32BIT

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

  47 config ANDROID_BINDER_IPC_SELFTEST
  48         bool "Android Binder IPC Driver Selftest"
  49         depends on ANDROID_BINDER_IPC
  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.
