| 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. |

| 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. |

| 54 | exhaustively with combinations of various buffer sizes and |
