The hardware only supports timeouts slightly below 3mins, but by using max_hw_heartbeat_ms we can let the kernel take care of supporting larger timeouts than that requested from userspace. Switching to max_hw_heartbeat_ms also means our set_timeout function now needs to configure the hardware to the minimum of either the requested timeout (in seconds) or the maximum supported by the user (in seconds).

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.
