> The proposed solution focuses on how many times empty polls are executed.
> The less the number of empty polls, means current core is busy with
> processing workload, therefore, the higher frequency is needed. The high
> empty poll number indicates the current core not doing any real work
> therefore, we can lower the frequency to safe power.

> In the current implementation, each core has 1 empty-poll counter which

> future to support multiple queues per core.
Applied with fixes for meson compilation, doxygen and doc.
