Every completion will update last_seen value in the unit of jiffies. last_seen field will be used to know if firmware is alive and is useful to detect firmware stall. Non blocking interface __wait_for_resp will have logic to detect firmware stall. After every 10 second interval if __wait_for_resp has not received completion for a given command it will check for firmware stall condition. If current jiffies is greater than last_seen jiffies + RCFW_FW_STALL_TIMEOUT_SEC * HZ, it is a firmware stall.

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.
