8850 | * Package states C8 and deeper are really deep PC states that can only be | |
8851 | * reached when all the devices on the system allow it, so even if the graphics | |
8852 | * device allows PC8+, it doesn't mean the system will actually get to these | |
8853 | * states. Our driver only allows PC8+ when going into runtime PM. | |
8854 | * | |
8855 | * The requirements for PC8+ are that all the outputs are disabled, the power | |
8856 | * well is disabled and most interrupts are disabled, and these are also | |
8857 | * requirements for runtime PM. When these conditions are met, we manually do | |
8858 | * the other conditions: disable the interrupts, clocks and switch LCPLL refclk | |
8859 | * to Fclk. If we're in PC8+ and we get an non-hotplug interrupt, we can hard | |
8860 | * hang the machine. | |
8861 | * | |
8862 | * When we really reach PC8 or deeper states (not just when we allow it) we lose | |
8863 | * the state of some registers, so when we come back from PC8+ we need to | |
8864 | * restore this state. We don't get into PC8+ if we're not in RC6, so we don't | |
8865 | * need to take care of the registers kept by RC6. Notice that this happens even | |
8866 | * if we don't put the device in PCI D3 state (which is what currently happens | |
8867 | * because of the runtime PM support). | |
8868 | * | |
8869 | * For more, read "Display Sequences for Package C8" on the hardware | |
8870 | * documentation. | |
