---help---
Binder is used in Android for both communication between processes,
and remote method invocation.
This means one Android process can call a method/routine in another
Android process, using Binder to identify, invoke and pass arguments
between said processes.
config ANDROID_BINDERFS
bool "Android Binderfs filesystem"
depends on ANDROID_BINDER_IPC
default n
---help---
Binderfs is a pseudo-filesystem for the Android Binder IPC driver
which can be mounted per-ipc namespace allowing to run multiple
instances of Android.
Each binderfs mount initially only contains a binder-control device.
It can be used to dynamically allocate new binder IPC devices via
ioctls.
config ANDROID_BINDER_DEVICES
string "Android Binder devices"
depends on ANDROID_BINDER_IPC
default "binder,hwbinder,vndbinder"
---help---
Default value for the binder.devices parameter.
The binder.devices parameter is a comma-separated list of strings
that specifies the names of the binder device nodes that will be
created. Each binder device has its own context manager, and is
therefore logically separated from the other devices.
config ANDROID_BINDER_IPC_SELFTEST
bool "Android Binder IPC Driver Selftest"
depends on ANDROID_BINDER_IPC
---help---
This feature allows binder selftest to run.
Binder selftest checks the allocation and free of binder buffers
exhaustively with combinations of various buffer sizes and
alignments.
