The architecture does not define an upper limit on how long a queue reset (RAPQ/ZAPQ) can take to complete. In order to ensure both the security requirements and prevent resource leakage and corruption in the hypervisor, it is necessary to remove the upper limit (200ms) the vfio_ap driver currently waits for a reset to complete. This, of course, may result in a hang which is a less than desirable user experience, but until a firmware solution is provided, this is a necessary evil.

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.
