Hi, Hackers,

Under Linux, the clock framework defines programming interfaces to support software management of the system clock tree. Is there similar framerwork/server on L4 variants?

No, we don't have a clock / frequency scaling framework. It also has to be divided between kernel and user land, so there is no easy solution.

We have done it before on an ARM-based embedded platform, however this was very specific to the underlying platform. Maybe we can discuss your use case in more detail to come up with a solution?

Best, Matthias.
