Introduce new API to expose symbols useful for debugging the GKI kernel. Symbols exported from this driver would be difficult to maintain via the traditional EXPORT_SYMBOL_GPL.

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.

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.

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.

Enables export of debug symbols that are useful for offline debugging

|
of a kernel. These symbols would be used in vendor modules to find
|
|
addresses of the core kernel symbols for vendor extensions.

This driver is statically compiled into kernel and maintains all the

required symbol addresses for vendor modules and provides necessary

interface vendor modules.
