Description
This message is informational in nature. It simply lists the precise frequencies for the runtime controllable kernel clock(s) and scalable system clock(s) in MHz.
Explanation
Kernel clocks (and system clocks for some platforms) are scalable. They can preserve functionality at the cost of performance by running at a lower frequency than requested. To be scalable, a clock must be driven by an MMCM where the control registers for the MMCM can be set by the runtime over AXI4-Lite. This item shows the final runtime controlled frequencies for all scalable clocks.
Recommendation
This message is of informational nature. It lists all scalable clocks and their achieved frequencies. If any of the achieved clock frequencies divert from the specified frequency, additional frequency scaling related messages will provide more detail.
