9097 | * When we really reach PC8 or deeper states (not just when we allow it) we lose | |
9098 | * the state of some registers, so when we come back from PC8+ we need to | |
9099 | * restore this state. We don't get into PC8+ if we're not in RC6, so we don't | |
9100 | * need to take care of the registers kept by RC6. Notice that this happens even | |
9101 | * if we don't put the device in PCI D3 state (which is what currently happens | |
9102 | * because of the runtime PM support). | |
9103 | * | |
9104 | * For more, read "Display Sequences for Package C8" on the hardware | |
9105 | * documentation. | |
