Description
PME Support: This field indicates the power states in which the IGD may assert
PME#. Hardwired to 0 to indicate that the IGD does not assert the PME# signal.
D2: The D2 power management state is not supported. This bit is hardwired to 0.
D1: Hardwired to 0 to indicate that the D1 power management state is not
supported.
Reserved
Device Specific Initialization (DSI): Hardwired to 1 to indicate that special
initialization of the IGD is required before generic class device driver is to use it.
Auxiliary Power Source: Hardwired to 0.
PME Clock: Hardwired to 0 to indicate IGD does not support PME# generation.
Version: Hardwired to 010b to indicate that there are 4 bytes of power
management registers implemented and that this device complies with revision
1.1 of the PCI Power Management Interface Specification
