10564 | * system Power Management (PM) to device with SLI-3 interface spec. When PM | |
10565 | * invokes this method, it restores the device's PCI config space state and | |
10566 | * fully reinitializes the device and brings it online. Note that as the | |
10567 | * driver implements the minimum PM requirements to a power-aware driver's | |
10568 | * PM for suspend/resume -- all the possible PM messages (SUSPEND, HIBERNATE, | |
10569 | * FREEZE) to the suspend() method call will be treated as SUSPEND and the | |
10570 | * driver will fully reinitialize its device during resume() method call, | |
10571 | * the device will be set to PCI_D0 directly in PCI config space before | |
10572 | * restoring the state. | |
10573 | * | |
10574 | * Return code | |
