We're taking into account both HW memory-accesses + CPU activity based on current CPU's frequency. For memory-accesses there is a kind of hysteresis in a form of "boosting" which is managed by the tegra30-devfreq driver. If current HW memory activity is higher than activity judged based of the CPU's frequency, then there is no need to schedule cpufreq_update_work because the result of the work will be a NO-OP. And thus, tegra_actmon_cpufreq_contribution() should return 0, meaning that at the moment CPU frequency doesn't contribute anything to the final decision about required memory clock rate.

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.
