8826 | * requirements for runtime PM. When these conditions are met, we manually do | |
8827 | * the other conditions: disable the interrupts, clocks and switch LCPLL refclk | |
8828 | * to Fclk. If we're in PC8+ and we get an non-hotplug interrupt, we can hard | |
8829 | * hang the machine. | |
8830 | * | |
8831 | * When we really reach PC8 or deeper states (not just when we allow it) we lose | |
8832 | * the state of some registers, so when we come back from PC8+ we need to | |
8833 | * restore this state. We don't get into PC8+ if we're not in RC6, so we don't | |
8834 | * need to take care of the registers kept by RC6. Notice that this happens even | |
8835 | * if we don't put the device in PCI D3 state (which is what currently happens | |
8836 | * because of the runtime PM support). | |
8837 | * | |
8838 | * For more, read "Display Sequences for Package C8" on the hardware | |
8839 | * documentation. | |

12429 | * start of vblank, which also occurs at start of hsync (on the | |
12430 | * last active line), the scanline counter will read vblank_start-1. | |

12432 | * On gen2 the scanline counter starts counting from 1 instead | |
12433 | * of vtotal-1, so we have to subtract one (or rather add vtotal-1 | |
12434 | * to keep the value positive), instead of adding one. | |
12435 | * | |
12436 | * On HSW+ the behaviour of the scanline counter depends on the output | |
12437 | * type. For DP ports it behaves like most other platforms, but on HDMI | |
12438 | * there's an extra 1 line difference. So we need to add two instead of | |

12445 | * to 1 so that the vblank timestamps come out correct when we query | |
12446 | * the scanline counter from within the vblank interrupt handler. | |
