Upon the G2H Notify-Err-Capture event, parse through the GuC Log Buffer (error-capture-subregion) and generate one or more capture-nodes. A single node represents a single "engine- instance-capture-dump" and contains at least 3 register lists: global, engine-class and engine-instance. An internal link list is maintained to store one or more nodes. Because the link-list node generation happen before the call to devcoredump, duplicate global and engine-class register lists for each engine-instance register dump if we find dependent-engine resets in a engine-capture-group. To avoid dynamically allocate the output nodes during gt reset, pre-allocate a fixed number of empty nodes up front (at the time of ADS registration) that we can consume from or return to an internal cached list of nodes.

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.
