I've confirmed that monitoring the package power usage as well as setting power limits appear to be working as expected. However, I do see in the logs:
[ 5.082632] intel_rapl: RAPL domain core detection failed [ 5.088370] intel_rapl: RAPL domain uncore detection failed So I'm not sure if the h/w simply doesn't support that, or if the driver could be improved here. In any case, adding the 0x3f makes the driver useful for me.
