PEP_COORDINATED_DEPENDENCY_OPTION structure (pepfx.h)

The PEP_COORIDNATED_DEPENDENCY_OPTION structure describes a coordinated idle state's dependency to the OS.

Syntax

typedef struct _PEP_COORDINATED_DEPENDENCY_OPTION {
  UCHAR   ExpectedStateIndex;
  BOOLEAN LooseDependency;
  BOOLEAN InitiatingState;
  BOOLEAN DependentState;
} PEP_COORDINATED_DEPENDENCY_OPTION, *PPEP_COORDINATED_DEPENDENCY_OPTION;

Members

ExpectedStateIndex

Supplies the index of the idle state (coordinated idle state or processor idle state) that must have already been entered/be entered by this idle transition.

LooseDependency

When FALSE, the OS must use synchronization to guarantee that the state referred to by this dependency has already been entered. When TRUE, the OS may perform best-effort coordination that the target state is entered. The PEP must set LooseDependency to TRUE if the ExpectedState is a processor state and has the WakesSpuriously flag set.

InitiatingState

Indicates if the OS may simultaneously enter the state referred to by this dependency. If FALSE, this state is only valid when another processor has previously entered it.

DependentState

Indicates if this state is a valid state for a dependent processor to be in.
