Power consumption and suspend to ram

[z4v4l]

So it seems that suspend to disk isn't trivial on ARM.

as anything not done. ARM as an architecture brings zero complication to that.

And indeed it seems that suspend to ram / sleep is not putting the cpu to sleep...

then it's not suspend to ram. all S states do put all CPUs off. not idle, not deep sleep, not anything but full off.

and honestly, again, until Rockchip jumps ACPI, this won't change. because all these efforts (manjaro) are mimicking. for STR, a capable firmware is needed, on PCs, this is done by the BIOS,UEFI/ACPI and the OS. manjaro here, hardly would do anything. for hibernation, it could be made by the OS purely, but eh, you do see how it goes.
