binder_alloc_selftest tests that alloc_new_buf handles page allocation and deallocation properly when allocate and free buffers. The test allocates 5 buffers of various sizes to cover all possible page alignment cases, and frees the buffers using a list of exhaustive freeing order. Test: boot the device with ANDROID_BINDER_IPC_SELFTEST config option enabled. Allocator selftest passes.

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.

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.

The Binder API has been changed to support both 32 and 64bit

applications in a mixed environment.
|

Enable this to support an old 32-bit Android user-space (v4.4 and

earlier).

Note that enabling this will break newer Android user-space.

Binder selftest checks the allocation and free of binder buffers
