Duplicating info at different places increases needed maintenance. Mabye above should be more about the kernel implementation details and the manpage should more include the bits a typical user wants to know? > What do you think? The POLL state is a bit confusing on X86 cpupower idle-info output. Also on X86 the CPU may decide to use other states than the kernel requested and the cpupower monitor tool should get used to see them. This directly affects the output/usage of the tool and to understand it, it should be documented in the manpage. IMO it's not bad to have a somewhat bigger manpage here. Especially on ARM, also the "ordinary" user wants to know about how/whether the cpu power functionalities work as expected without the need of looking at the kernel sources. For now I could only try out cpupower on an ARM platform with cpufreq support. Would be great if someone could give cpupower idle-info a try on such a machine. Think of a typical user, not a kernel hacker and what he needs to know to interpret and understand the output. Maybe it's self-explanatory already, maybe the one or other arch specific bit should get explained?
