[Richland Kaveri] IddVal returns false value for highest P-state
Hello Kevin,
I just found this small bug, this case the calculated Wattage is inaccurate. You'll find the values returned for Richland:

Unfortunately I couldn't figure out how to convert the "39:32" bits to hex format for reading with rdmsr. I tried to understand the getDec function, but no success...
Best regards
Running the program with the debug flag, shows the registers :)
