If the panel supports VRR it must be capable of accepting timings with arbitrary vblank length, within the valid VRR range. Use that fact to allow the user to request any refresh rate they like. We simply pick the next highest fixed mode from our list, and adjust the vblank to get the desired refresh rate in the end. Of course currently everything to do with the vrefresh is using 1Hz precision, so might not be exact. But we can improve that in the future by just upping our vrefresh precision.

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.
