The FFA_MSG_SEND2 can be used to transmit a partition message from the Tx buffer of the sender(the driver in this case) endpoint to the Rx buffer of the receiver endpoint. An invocation of the FFA_MSG_SEND2 transfers the ownership of the Tx buffer to the receiver endpoint(or any intermediate consumer). Completion of an FFA_MSG_SEND2 invocation transfers the ownership of the buffer back to the sender endpoint. The framework defines the FFA_MSG_SEND2 interface to transmit a partition message from the Tx buffer of the sender to the Rx buffer of a receiver and inform the scheduler that the receiver must be run.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
