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