Windows Driver Kit DDI reference (nc-d3d12umddi-pfnd3d12ddi_set_background_processing_mode_0063)

PFND3D12DDI_SET_BACKGROUND_PROCESSING_MODE_0063 callback function

Description

When an application changes background processing mode, PFND3D12DDI_SET_BACKGROUND_PROCESSING_MODE_0063 is called to inform the UMD of the new settings.

Parameters

hRTDevice [in]

The handle of the device for the driver to use when it calls back into the runtime.

Mode

A D3D12DDI_BACKGROUND_PROCESSING_MODE_0062 enumeration that represents the background processing mode.

MeasurementsAction

A D3D12DDI_MEASUREMENTS_ACTION_0062 enumeration that represents the measurement action.

pbFurtherMeasurementsDesired

Pointer to a BOOL, indicating whether further measurements are desired.

Prototype

//Declaration

PFND3D12DDI_SET_BACKGROUND_PROCESSING_MODE_0063 Pfnd3d12ddiSetBackgroundProcessingMode0063;

// Definition

void Pfnd3d12ddiSetBackgroundProcessingMode0063
(
    D3D12DDI_HDEVICE hRTDevice
    D3D12DDI_BACKGROUND_PROCESSING_MODE_0062 Mode
    D3D12DDI_MEASUREMENTS_ACTION_0062 MeasurementsAction
    BOOL *pbFurtherMeasurementsDesired
)
{...}

Remarks

Background processing work must only ever be used for optimization purposes. These work items must not affect functional correctness of the implementation.
