NXP devices with QBMan version 5 and above can enable software portals that are memory backed. This allows the portal to be mapped as cacheable/sharable (same as all normal memory) so that portals can freely migrate between cores and clusters in the SoC. The driver will enable this mode by default when appropriate HW support is detected.

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 Restructured Text 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.
