BugLink: http://bugs.launchpad.net/bugs/1591802

MSR_CONFIG_TDP_NOMINAL:
should print all 8 bits of base_ratio (bit 0:7) 0xFF

MSR_CONFIG_TDP_LEVEL_1:
should print all 15 bits of PKG_MIN_PWR_LVL1 (bit 48:62) 0x7FFF
should print all 15 bits of PKG_MAX_PWR_LVL1 (bit 32:46) 0x7FFF
should print all 8 bits of LVL1_RATIO (bit 16:23) 0xFF
should print all 15 bits of PKG_TDP_LVL1 (bit 0:14) 0x7FFF

And the same modification to MSR_CONFIG_TDP_LEVEL_2.

MSR_TURBO_ACTIVATION_RATIO:
should print all 8 bits of MAX_NON_TURBO_RATIO (bit 0:7) 0xFF
