Integrated Graphics Device (D2:F1) Registers (Intel® 82945G/82945GC/82945GZ GMCH Only) 8.1.21 BSM—Base of Stolen Memory Register (D2:F1) PCI Device: 2 Address Offset: 5Ch Default Value: 07800000h Access: RO Size: 32 bits This register is a copy of Device 2, Function 0. It has the same read, write attributes as Function 0. It is implemented as common hardware with two access addresses. 8.1.22 PMCAPID—Power Management Capabilities ID (D2:F1) PCI Device: 2 Address Offset: D0h Default Value: 0001h Access: RO Size: 16 bits This register is a copy of Device 2, Function 0. It has the same read, write attributes as Function 0. It is implemented as common hardware with two access addresses. 8.1.23 PMCAP—Power Management Capabilities (D2:F1) PCI Device: 2 Address Offset: D2h Default Value: 0022h Access: RO Size: 16 bits This register is a copy of Device 2, Function 0. It has the same read, write attributes as Function 0. It is implemented as common hardware with two access addresses. 200 Intel ® 82945G/82945GZ/82945GC GMCH and 82945P/82945PL MCH Datasheet
Integrated Graphics Device (D2:F1) Registers (Intel® 82945G/82945GC/82945GZ GMCH Only) 8.1.24 PMCS—Power Management Control/Status (D2:F1) PCI Device: 2 Address Offset: D4h Default Value: 0000h Access: RO, R/W Size: 16 bits Bit Access & Default 15 RO 0b 14:9 Reserved 8 RO 0b 7:2 Reserved 1:0 R/W 00b Description PME_Status: This bit is 0 to indicate that IGD does not support PME# generation from D3 (cold). PME_En: This bit is 0 to indicate that PME# assertion from D3 (cold) is disabled. Power State: This field indicates the current power state of the IGD and can be used to set the IGD into a new power state. If software attempts to write an unsupported state to this field, the write operation must complete normally on the bus, but the data is discarded and no state change occurs. On a transition from D3 to D0 the graphics controller is optionally reset to initial values. Behavior of the graphics controller in supported states is detailed in the power management section. 00 = D0 (Default) 01 = D1 (Not Supported) 10 = D2 (Not Supported) 11 = D3 8.1.25 SWSMI—Software SMI (D2:F1) PCI Device: 2 Address Offset: E0h Default Value: 0000h Access: R/W Size: 16 bits This register is a copy of Device 2, Function 0. It has the same read, write attributes as Function 0. It is implemented as common hardware with two access addresses. Intel ® 82945G/82945G/82945GC GMCH and 82945P/82945PL MCH Datasheet 201
