Windows Driver Kit DDI reference (nc-d3d10umddi-pfnd3d11ddi_calcprivatedeferredcontextsize)

PFND3D11DDI_CALCPRIVATEDEFERREDCONTEXTSIZE callback function

Description

The CalcPrivateDeferredContextSize function determines the size of the user-mode display driver's private region of memory (that is, the size of internal driver structures, not the size of the resource video memory) for a deferred context.

Parameters

`unnamedParam1`

hDevice [in]

A handle to the display device (graphics context).

`unnamedParam2`

pCalcPrivateDeferredContextSize [in]

A pointer to a D3D11DDIARG_CALCPRIVATEDEFERREDCONTEXTSIZE structure that describes the parameters that the user-mode display driver uses to calculate the size of the memory region.

Return value

CalcPrivateDeferredContextSize returns the size of the memory region that the driver requires to create a deferred context.

Remarks

The driver is only required to implement CalcPrivateDeferredContextSize if the driver supports the D3D11DDICAPS_COMMANDLISTS_BUILD_2 capability that can be returned in the D3D11DDI_THREADING_CAPS structure from a call to the GetCaps(D3D10_2) function.
