Afaik there is some "read-only"/monitor code in turbostat, but it is not intended to add any modifying code in there? I would like to avoid yet another (Intel) CPU specific userspace tool, like: tools/power/x86/x86_energy_perf_policy tools/power/x86/turbostat and it would be great if userspace bits could be added to cpupower utility tools/power/cpupower I searched for rapl and powercap in the MAINTAINERS list, but there wasn't any match. Is there a candidate (Jacob?) who might be the right one or who volunteers for this? Thanks for any hints and any discussion input, Thomas
