DXGK_DSI_CONTROL_TRANSMISSION_MODE enumeration (dispmprt.h)

  • Article

Describes an override for the transmission mode, allowing the OEM panel driver to specify whether low power or high performance mode should be used for write packets in the transmission to mitigate cases where a panel only supports one of the modes.

Syntax

typedef enum _DXGK_DSI_CONTROL_TRANSMISSION_MODE {
  DXGK_DCT_DEFAULT,
  DXGK_DCT_FORCE_LOW_POWER,
  DXGK_DCT_FORCE_HIGH_SPEED
} DXGK_DSI_CONTROL_TRANSMISSION_MODE;

Constants

 
DXGK_DCT_DEFAULT
Graphics driver selects transmission mode based on size of payload, current transmission mode and host capabilities. This allows the driver to use the most optimal mode of transmission so should be used unless the OEM panel driver has hardware limitations which the graphics driver is not expected to be aware of which require one specific transmission mode.
DXGK_DCT_FORCE_LOW_POWER
Write packets should use low-power transmission mode or failed if that is not available.
DXGK_DCT_FORCE_HIGH_SPEED
Write packets should use high-speed transmission mode or failed if that is not available.
