The PCI_PMCSR_BSE structure is used to report the contents of the power management control status register for PCI bridge support extensions.
Syntax
typedef struct _PCI_PMCSR_BSE {
UCHAR Rsvd1;
UCHAR D3HotSupportsStopClock;
UCHAR BusPowerClockControlEnabled;
} PCI_PMCSR_BSE, *PPCI_PMCSR_BSE;
Members
Rsvd1
Reserved.
D3HotSupportsStopClock
Indicates how the power state of a secondary bus is affected when the primary bus transitions to a D3 power state. For a detailed explanation of the values in this member and how they affect the relationship between the primary and secondary buses, see the PCI Power Management Specification.
BusPowerClockControlEnabled
Indicates, when 1, that the bus's power clock control mechanism is enabled. A value of 0 indicates that the bus power clock control mechanism is disabled. For a detailed explanation of the meaning of this member, see the PCI Power Management Specification.
