1135 | /** |
1136 | * RC6 is a special power stage which allows the GPU to enter an very | |
1137 | * low-voltage mode when idle, using down to 0V while at this stage. This | |
1138 | * stage is entered automatically when the GPU is idle when RC6 support is | |
1139 | * enabled, and as soon as new workload arises GPU wakes up automatically as well. | |
1140 | * | |
1141 | * There are different RC6 modes available in Intel GPU, which differentiate | |
1142 | * among each other with the latency required to enter and leave RC6 and | |
1143 | * voltage consumed by the GPU in different states. | |
1144 | * | |
1145 | * The combination of the following flags define which states GPU is allowed | |
1146 | * to enter, while RC6 is the normal RC6 state, RC6p is the deep RC6, and | |
1147 | * RC6pp is deepest RC6. Their support by hardware varies according to the | |
1148 | * GPU, BIOS, chipset and platform. RC6 is usually the safest one and the one | |
1149 | * which brings the most power savings; deeper states save more power, but | |
1150 | * require higher latency to switch to and wake up. | |
