To support FastRPC Context Banks which aren't mapped via the SMMU, make the whole reserved memory region available to the DSP to allow access to coherent buffers. This is performed by assigning the memory to the DSP via a hypervisor call to set the correct permissions for the Virtual Machines on the DSP. This is only necessary when a memory region is provided for SLPI DSPs so guard this with a domain ID check.

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.
