For reasons that I'm sure made perfect sense at the time we were opting to defer the iova alloc / pin on the ringbuffer until HW init time so when we moved to iova reference counting we ended up adding a reference count every time the hardware started. Not that it mattered (because the ring is always around) but it did make the debug output look odd. Allocate and pin the iova at create time instead.

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.
