we addressed this to some degree already some time ago in an
experimental way (see github issue 813 [0], branches issue_813 and
issue_813_fancy of my Genode repository).

With the commits you can collect on Fiasoc.OC (x86 and ARM) for each
thread and on Nova for each Scheduling Context the elapsed runtime.
Additionally the Cpu idle times can be requested. Based on that you may
calculate Cpu utilization times.

The commits contain an example run script cpu_monitor.run for easy
testing. The issue_813_fancy branch contains and adapted demo.run script
so that in launchpad the Cpu utilization of the started process are shown.

Regards,

Alex.
