PEP_COMPONENT_PERF_STATE_REQUEST structure (pepfx.h)

  • Article

The PEP_COMPONENT_PERF_STATE_REQUEST structure specifies a performance state (P-state) set and a new performance level to assign to this set.

Syntax

typedef struct _PEP_COMPONENT_PERF_STATE_REQUEST {
  ULONG Set;
  union {
    ULONG     StateIndex;
    ULONGLONG StateValue;
  };
} PEP_COMPONENT_PERF_STATE_REQUEST, *PPEP_COMPONENT_PERF_STATE_REQUEST;

Members

Set

The index of the P-state set to which to assign the new performance level. If N is the number of P-state sets specified for this component, P-state set indexes range from 0 to N–1. The PEP previously specified the number of P-state sets in response to a PEP_DPM_QUERY_COMPONENT_PERF_CAPABILITIES notification.

StateIndex

The index of the discrete value to use as the new performance level. This member is used if the performance level for this P-state set is expressed as an index into an array of discrete values. The PEP previously supplied this array of discrete values in response to a PEP_DPM_QUERY_COMPONENT_PERF_STATES notification.

StateValue

The value to use as the new performance level. This member is used if the performance level for this P-state set is expressed as a value in a continuous range of possible values. The PEP previously supplied this range in response to a PEP_DPM_QUERY_COMPONENT_PERF_SET notification.

Remarks

The unnamed union contains a value that indicates the new performance level that has been selected for this P-state set.

The PerfRequests member of the PEP_REQUEST_COMPONENT_PERF_STATE structure is a pointer to an array of PEP_COMPONENT_PERF_STATE_REQUEST structures.
