| 1081 | * This struct tracks the state needed for the Package C8+ feature. |
| 1082 | * |
| 1083 | * Package states C8 and deeper are really deep PC states that can only be |
| 1084 | * reached when all the devices on the system allow it, so even if the graphics |
| 1085 | * device allows PC8+, it doesn't mean the system will actually get to these |
| 1086 | * states. |
| 1087 | * |
| 1088 | * Our driver only allows PC8+ when all the outputs are disabled, the power well |
| 1089 | * is disabled and the GPU is idle. When these conditions are met, we manually |
| 1090 | * do the other conditions: disable the interrupts, clocks and switch LCPLL |
| 1091 | * refclk to Fclk. |
| 1092 | * |
| 1093 | * When we really reach PC8 or deeper states (not just when we allow it) we lose |
| 1094 | * the state of some registers, so when we come back from PC8+ we need to |
| 1095 | * restore this state. We don't get into PC8+ if we're not in RC6, so we don't |
| 1096 | * need to take care of the registers kept by RC6. |
| 1097 | * |
| 1098 | * The interrupt disabling is part of the requirements. We can only leave the |
| 1099 | * PCH HPD interrupts enabled. If we're in PC8+ and we get another interrupt we |
| 1100 | * can lock the machine. |
| 1101 | * |
| 1102 | * Ideally every piece of our code that needs PC8+ disabled would call |
| 1103 | * hsw_disable_package_c8, which would increment disable_count and prevent the |
| 1104 | * system from reaching PC8+. But we don't have a symmetric way to do this for |
| 1105 | * everything, so we have the requirements_met and gpu_idle variables. When we |
| 1106 | * switch requirements_met or gpu_idle to true we decrease disable_count, and |
| 1107 | * increase it in the opposite case. The requirements_met variable is true when |
| 1108 | * all the CRTCs, encoders and the power well are disabled. The gpu_idle |
| 1109 | * variable is true when the GPU is idle. |
| 1110 | * |
| 1111 | * In addition to everything, we only actually enable PC8+ if disable_count |
| 1112 | * stays at zero for at least some seconds. This is implemented with the |
| 1113 | * enable_work variable. We do this so we don't enable/disable PC8 dozens of |
| 1114 | * consecutive times when all screens are disabled and some background app |
| 1115 | * queries the state of our connectors, or we have some application constantly |
| 1116 | * waking up to use the GPU. Only after the enable_work function actually |
| 1117 | * enables PC8+ the "enable" variable will become true, which means that it can |
| 1118 | * be false even if disable_count is 0. |
| 1119 | * |
| 1120 | * The irqs_disabled variable becomes true exactly after we disable the IRQs and |
| 1121 | * goes back to false exactly before we reenable the IRQs. We use this variable |
| 1122 | * to check if someone is trying to enable/disable IRQs while they're supposed |
| 1123 | * to be disabled. This shouldn't happen and we'll print some error messages in |
| 1124 | * case it happens, but if it actually happens we'll also update the variables |
| 1125 | * inside struct regsave so when we restore the IRQs they will contain the |
| 1126 | * latest expected values. |
| 1127 | * |
| 1128 | * For more, read "Display Sequences for Package C8" on our documentation. |

| 1671 | * RC6 is a special power stage which allows the GPU to enter an very |
| 1672 | * low-voltage mode when idle, using down to 0V while at this stage. This |
| 1673 | * stage is entered automatically when the GPU is idle when RC6 support is |
| 1674 | * enabled, and as soon as new workload arises GPU wakes up automatically as well. |
| 1675 | * |
| 1676 | * There are different RC6 modes available in Intel GPU, which differentiate |
| 1677 | * among each other with the latency required to enter and leave RC6 and |
| 1678 | * voltage consumed by the GPU in different states. |
| 1679 | * |
| 1680 | * The combination of the following flags define which states GPU is allowed |
| 1681 | * to enter, while RC6 is the normal RC6 state, RC6p is the deep RC6, and |
| 1682 | * RC6pp is deepest RC6. Their support by hardware varies according to the |
| 1683 | * GPU, BIOS, chipset and platform. RC6 is usually the safest one and the one |
| 1684 | * which brings the most power savings; deeper states save more power, but |
| 1685 | * require higher latency to switch to and wake up. |
