Hi,

Hi,

Here is what I am proposing, in reply to all your comments:

1) rename the events to match Thomas's proposal:
    power:power_cpu_cstate
    power:power_cpu_pstate
    power:power_cpu_sstate

If that sstate thing is going to mean "suspend", then please drop it.
"Suspend" is not a state, let alone a CPU state.  It is a procedure by which
the (entire) system is put into a sleep state (that is not confined to CPUs).

there are also non-suspend S states, like S0i1 and S0i3 (supported in 

the current Intel "Moorestown" platform)

so it's slightly more complex than "just" suspend :)
