This sounds like it should be a hwmon driver. > The DCM collects and tallies data over a period of time in the background, > without utilizing any resources on the host (CPU, memory, etc).

Though this is a bit odd for the subsystem I don't think it's too far out of what other hwmon chips can do, some of them do have longer term stats than just instantaneous readings. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
