| 1099 | * RC6 is a special power stage which allows the GPU to enter an very |
| 1100 | * low-voltage mode when idle, using down to 0V while at this stage. This |
| 1101 | * stage is entered automatically when the GPU is idle when RC6 support is |
| 1102 | * enabled, and as soon as new workload arises GPU wakes up automatically as well. |
| 1103 | * |
| 1104 | * There are different RC6 modes available in Intel GPU, which differentiate |
| 1105 | * among each other with the latency required to enter and leave RC6 and |
| 1106 | * voltage consumed by the GPU in different states. |
| 1107 | * |
| 1108 | * The combination of the following flags define which states GPU is allowed |
| 1109 | * to enter, while RC6 is the normal RC6 state, RC6p is the deep RC6, and |
| 1110 | * RC6pp is deepest RC6. Their support by hardware varies according to the |
| 1111 | * GPU, BIOS, chipset and platform. RC6 is usually the safest one and the one |
| 1112 | * which brings the most power savings; deeper states save more power, but |
| 1113 | * require higher latency to switch to and wake up. |
