基本信息

功能说明

标准命令，设置当前设备的 ACPI 状态。 This command is provided to allow system software to tell a controller the present ACPI power state of the system. The Set ACPI Power State command can also be used as a mechanism for setting elements of the platform management subsystem to a particular power state. This is an independent setting that may not necessarily match the actual power state of the system. This command is used to enable the reporting of the power state, it does not control or change the power state.

ACPI System Power State to set.
Power states are mutually exclusive. Only one state can be set at a time.
[7]
1b = set system power state
0b
don’t change system power state
[6:0] System Power State enumeration
00h set S0 / G0 working
01h set S1 hardware context maintained, typically equates to processor/chip set clocks stopped
02h set S2 typically equates to stopped clocks with processor/cache context lost
03h set S3 typically equates to “suspend-to-RAM”
04h set S4 typically equates to “suspend-to-disk”
05h set S5 / G2 soft off
06h set S4/S5 sent when message source cannot differentiate between S4 and S5
07h set G3 mechanical off
08h sleeping sleeping - cannot differentiate between S1-S3.
09h G1 sleeping sleeping - cannot differentiate between S1-S4
0Ah set override S5 entered by override
20h set Legacy On Legacy On (indicates On for system that don’t support ACPI or have ACPI capabilities disabled)
21h set Legacy Off Legacy Soft-Off
2Ah set unknown system power state unknown
7Fh no change Use this value when communicating a change the device power state without indicating a change to the system power state.

ACPI Device Power State to set.
Power states are mutually exclusive. Only one state can be set at a time.
[7]
1 = set device power state
0 = don't change device power state
[6:0] - Device Power State enumeration
00h set D0
01h set D1
02h set D2
03h set D3
2Ah set unknown
7Fh no changeUse this value when communicating a change the system power state without indicating a change to the device power state.
