While booting the CRD, a series of CMA allocation errors can be seen in the kernel log: cma: cma_alloc: reserved: alloc failed, req-size: 128 pages, ret: -12 Growing the CMA region and querying /proc/meminfo indicates that a newly booted system (currently) uses 64MB CMA. Define a memory region sufficiently large for the current use cases, to avoid forcing users to add this themselves, through command line parameters etc. While fixing the CRD define the same region for the X13s.

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.
