DXGK_I2C_INTERFACE structure

Description

The DXGK_I2C_INTERFACE structure contains pointers to functions in the I2C interface, which is implemented by the display miniport driver.

Members

`Size`

The size, in bytes, of this structure.

`Version`

The version number of the I2C interface. Version number constants are defined in Dispmprt.h (for example, DXGK_I2C_INTERFACE_VERSION_1).

`Context`

A pointer to a private context block.

`InterfaceReference`

A pointer to an interface reference function that is implemented by the display miniport driver.

`InterfaceDereference`

A pointer to an interface dereference function that is implemented by the display miniport driver.

`DxgkDdiI2CTransmitDataToDisplay`

A pointer to the display miniport driver's DxgkDdiI2CTransmitDataToDisplay function.

`DxgkDdiI2CReceiveDataFromDisplay`

A pointer to the display miniport driver's DxgkDdiI2CReceiveDataFromDisplay function.

Remarks

A kernel-mode component that needs to use the I2C interface calls the display miniport driver's DxgkDdiQueryInterface function.
