ICH7 and System Power States
shows the power states defined for ICH7-based platforms. The state names
Full On: Processor operating. Individual devices may be shut down to save
power. The different processor operating levels are defined by Cx states, as
shown in
processor using the STPCLK# signal to reduce power consumption. The throttling
can be initiated by software or by the operating system or BIOS.
Auto-Halt: Processor has executed an AutoHalt instruction and is not executing
code. The processor snoops the bus and maintains cache coherency.
Stop-Grant: The STPCLK# signal goes active to the processor. The processor
performs a Stop-Grant cycle, halts its instruction stream, and remains in that
state until the STPCLK# signal goes inactive. In the Stop-Grant state, the
processor snoops the bus and maintains cache coherency.
