For verifying reciving the EI interrupts, we need to hold the GPU in very precise conditions (in terms of C0 cycles during the EI). If we preempt the busy load to handle the heartbeat, this may perturb the busy load causing us to miss the interrupt. The other tests, while not as time sensitive, may also be slightly perturbed, so apply the heartbeat protection across all the measurements.

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.
