H A Dbinderfs.rst6 Android binderfs is a filesystem for the Android binder IPC mechanism. It
7 allows to dynamically add and remove binder devices at runtime. Binder devices
8 located in a new binderfs instance are independent of binder devices located in
10 to get a set of private binder devices.
18 mount -t binder binder /dev/binderfs
21 In a fresh instance of binderfs no binder devices will be present. There will
22 only be a ``binder-control`` device which serves as the request handler for
31 binderfs instances can be mounted with a limit on the number of binder
34 of binder devices can be allocated in this binderfs instance.
37 Using ``stats=global`` enables global binder statistics.
