DXGK_POWER_P_STATE structure

  • Article

[This documentation is preliminary and is subject to change.]

Used in calls to the DxgkDdiQueryAdapterInfo function to specify the effective speed of a GPU node to handle standard graphics workloads.

Syntax

typedef struct _DXGK_POWER_P_STATE {
  ULONG     NominalPower;
  ULONG     OperatingFrequency;
  ULONGLONG TransitionLatencies[DXGK_MAX_P_STATES];
  ULONGLONG ResidencyRequirement;
} DXGK_POWER_P_STATE, *PDXGK_POWER_P_STATE;

Members

  • NominalPower
    TBD

  • OperatingFrequency
    The operating frequency, in MHz, for this P-state.

    This value reflects the effective performance of the GPU node to handle standard workloads. So twice the value means that the node handles a standard workload in roughly half the time.

  • TransitionLatencies
    TBD

  • ResidencyRequirement
    TBD

Remarks

For more info on how to manage P-states, see Power management using P-states.
