*
* There are different RC6 modes available in Intel GPU, which differentiate
* among each other with the latency required to enter and leave RC6 and
* voltage consumed by the GPU in different states.
*
* The combination of the following flags define which states GPU is allowed
* to enter, while RC6 is the normal RC6 state, RC6p is the deep RC6, and
* RC6pp is deepest RC6. Their support by hardware varies according to the
* GPU, BIOS, chipset and platform. RC6 is usually the safest one and the one
* which brings the most power savings; deeper states save more power, but
* require higher latency to switch to and wake up.
