Since workqueues are created per CPU, the works scheduled to this workqueues are run on the CPU they were assigned. It may result in overloaded CPU that is not able to handle virtchnl messages in relatively short time. Allocating workqueue with WQ_UNBOUND and WQ_HIGHPRI flags allows scheduler to queue virtchl messages on less loaded CPUs, what eliminates delays.

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.
