DXGKARG_CONTROLINTERRUPT3 structure (d3dkmddi.h)
The DXGKARG_CONTROLINTERRUPT3 structure is used in DxgkDdi_ControlInterrupt3 calls to describe the state of interrupts.
Syntax
typedef struct _DXGKARG_CONTROLINTERRUPT3 {
DXGK_INTERRUPT_TYPE InterruptType;
union {
DXGK_INTERRUPT_STATE InterruptState;
DXGK_CRTC_VSYNC_STATE CrtcVsyncState;
};
D3DDDI_VIDEO_PRESENT_SOURCE_ID VidPnSourceId;
} DXGKARG_CONTROLINTERRUPT3;
Members
InterruptType
A DXGK_INTERRUPT_TYPE enumeration indicating the type of interrupt.
InterruptState
A DXGK_INTERRUPT_STATE enumeration that indicates whether interrupts are enabled for the driver.
CrtcVsyncState
A DXGK_CRTC_VSYNC_STATE enumeration that indicates whether VSYNCs are enabled if interrupts are also enabled for the driver.
VidPnSourceId
The unique ID of the VidPnSource on which to control the VSync. This member only applies to VSync interrupts. VidPnSourceId can be one of the following values:
| Value | Meaning |
|---|---|
| 0 to (number of actual VidPnSources-1) | Identifies a particular VidPnSource |
| D3DDDI_ID_ALL | VSync is to be controlled on every VidPnSource of the adapter. The OS will set this value in certain scenarios where it cannot determine the particular VidPnSource to control, or in scenarios such as adapter termination where VSync needs to be disabled globally across all VidPnSources. |
Remarks
InterruptState and CrtcVsyncState are members of a union.
