Introduce a heartbeat-based Timeout Detection and Recovery (TDR) mechanism. The enhancement aims to improve the reliability of device hang detection by monitoring heartbeat updates. Each progressing inference will update heartbeat counter allowing driver to monitor its progression. Limit maximum number of reschedules when heartbeat indicates progression to 30. This increases the maximum running time of single inference to about 60 seconds. The heartbeat mechanism provides a more robust method for detecting device hangs, potentially reducing false positive recoveries due to long running inferences.

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.
