DXGKDDI_CONTROLINTERRUPT2 callback function (d3dkmddi.h)

The DxgkDdi_ControlInterrupt2 function enables or disables the given interrupt type on the graphics hardware.

Syntax

DXGKDDI_CONTROLINTERRUPT2 DxgkddiControlinterrupt2;

NTSTATUS DxgkddiControlinterrupt2(
  IN_CONST_HANDLE hAdapter,
  IN_CONST_DXGKARG_CONTROLINTERRUPT2 InterruptControl
)
{...}

Parameters

hAdapter

[in] A handle to the adapter object for the graphics processing unit (GPU). The driver returned this handle in the MiniportDeviceContext parameter from a call to its DxgkDdiAddDevice function.

InterruptControl

[in] A DXGKARG_CONTROLINTERRUPT2 structure that supplies the interrupt type, as well as the VSYNC state.

Return value

DxgkDdi_ControlInterrupt2 returns one of the following values:

Return code Description
STATUS_SUCCESS The interrupt type was successfully enabled or disabled on the graphics hardware.
STATUS_NOT_IMPLEMENTED DxgkDdi_ControlInterrupt2 does not support enabling or disabling the specified interrupt type.

Remarks

Only one of DxgkDdiControlInterrupt2 or DxgkDdi_ControlInterrupt3 will be used by the OS during the lifetime of an adapter.

WDDM 2.7 drivers that do not implement DxgkDdi_ControlInterrupt3 are opting out of independent VidPn VSync control, and the OS will only call DxgkDdi_ControlInterrupt2. The DXGK_DRIVERCAPS->IndependentVidPnVSync capability must be 0 in drivers that do not support DxgkDdi_ControlInterrupt3; otherwise, the OS will fail adapter initialization. If driver does implement DxgkDdi_ControlInterrupt3, then the capability can be set to 0 or 1 to indicate Per-VidPn support.

Requirements

   
Minimum supported client Available in Windows 10 and later versions of the Windows operating systems.
Target Platform Desktop
Header d3dkmddi.h (include D3dkmddi.h)
