In addition to the already defined REQUEST HXG message format, which is used when sender expects some confirmation or data, HXG protocol includes definition of the FAST REQUEST message, that may be used when sender does not expect any useful data to be returned. Using this instead of GUC_HXG_TYPE_EVENT for non-blocking CTB requests will allow GuC to send back GUC_HXG_TYPE_RESPONSE_FAILURE in case of errors. Note that it is not possible to return such errors to the caller, since this is for non-blocking calls and the related fence is not stored. Instead such messages are treated as unexpected, which will give an indication of potential GuC misprogramming that warrants extra debugging effort.

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.
