XNACK mode controls the SQ RETRY_DISABLE setting that determines, whether recoverable page faults can be supported on GFXv9 hardware. Only on Aldebaran we can support different processes running with different XNACK modes. On older chips all processes must use the same RETRY_DISABLE setting. However, processes not relying on recoverable page faults can work with RETRY enabled. This means XNACK off is always available as a fallback so we can use the same mode on all GPUs in a process.

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.
