The RING_INT_SRC_RPT_PTR register points to a cacheline in memory to which an engine must report as source of interrupt prior to generating an interrupt to the host. The RING_INT_STATUS_RPT_PTR register points to the first cacheline of the Interrupt Status Report (ISR) page (4KB) in graphics memory to which all engines report their interrupt status. The RING_IMR register has the interrupt enables and interrupt masks for an engine. We will refer to these registers shortly.

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.
