Power/Energy counter access

Ali Saidi

Has anyone read the power/energy counters on Juno from Linux? If I remember right on tc2 they were exposed via hwmon, but the the devices aren't listed in the Juno DTS file.

Thanks,

Ali

    What exactly are you planning to use them for ?

    These are memory mapped registers and can be easily read via simple tool

    like devmem. The main reason we don't have hwmon interface like TC2 yet is

    we don't have CPU PM feature enabled.
