  • Article

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

Specifies the P-states that a GPU node supports.

Syntax

typedef struct _DXGK_POWER_P_COMPONENT {
  ULONG                        StateCount;
  DXGK_POWER_P_STATE           States[DXGK_MAX_P_STATES];
  DXGK_POWER_COMPONENT_P_FLAGS Flags;
} DXGK_POWER_P_COMPONENT;

Members

  • StateCount
    The number of P-states that the GPU node supports, up to a maximum value of DXGK_MAX_P_STATES (a value of 32). Each P-state, specified in the States member, corresponds to a different processor clock rate and voltage.

  • States
    The speed of a GPU node to handle standard graphics workloads, specified by the DXGK_POWER_P_STATE structure.

  • Flags
    Reserved for system use. Do not use in your driver.
