All these software depend on proprietary interfaces (Intel RAPL (oldest), Nvidia, Android..) Wondering how to do the same for RPi’s?

Wondering how to do the same for RPi’s?
- wmf 5y agoThere are no standard interfaces for power measurement. Given the cost-cutting philosophy behind RPi I assume the relevant sensors simply aren't there.
- zekrioca 5y agoMaybe we could use software for emulating such sensors.
- eric__cartman 5y agoFor starters you could always measure the power consumption that the Pi pulls from the USB power supply. As long as you don't change many variables when comparing software (like plugging in additional peripherals) it should be a decent way to get an idea of the power draw of the whole system under different circumstances. Or just measure the CPU usage and naively assume that lower CPU usage always means lower power draw.
