I got below output on my laptop:

    |Mperf               || Idle_Stats                
CPU | C0   | Cx   | Freq || POLL | C1   | C2   | C3   
   0| 36.00| 64.00|   820||1843411670376227.2|1843411670376692.2|  0.00|  0.00
   1| 44.69| 55.31|   920||  0.00|  0.00|  0.00|  0.00

Seems below patch fix it:

Thanks,
Yong
