  • Article

The DXGK_DISPLAYMUX_RUNTIME_STATUS enumeration specifies the runtime status level of automatic display switch (ADS) support that the driver provides.

Syntax

typedef enum _DXGK_DISPLAYMUX_RUNTIME_STATUS {
  DXGK_DISPLAYMUX_RUNTIME_STATUS_UNINITIALIZED = 0,
  DXGK_DISPLAYMUX_RUNTIME_STATUS_OK = 1,
  DXGK_DISPLAYMUX_RUNTIME_STATUS_NO_GPU_SUPPORT = 2,
  DXGK_DISPLAYMUX_RUNTIME_STATUS_NON_CRITICAL_SYSTEM_INFO_MISSING = 3,
  DXGK_DISPLAYMUX_RUNTIME_STATUS_CRITICAL_SYSTEM_INFO_MISSING = 4
} DXGK_DISPLAYMUX_RUNTIME_STATUS, *PDXGK_DISPLAYMUX_RUNTIME_STATUS;

Constants

 
DXGK_DISPLAYMUX_RUNTIME_STATUS_UNINITIALIZED
Value: 0
A variable of this enumeration type hasn't yet been assigned a meaningful value.
DXGK_DISPLAYMUX_RUNTIME_STATUS_OK
Value: 1
The GPU supports ADS and the driver has obtained required information from the system.
DXGK_DISPLAYMUX_RUNTIME_STATUS_NO_GPU_SUPPORT
Value: 2
The GPU doesn't support ADS.
DXGK_DISPLAYMUX_RUNTIME_STATUS_NON_CRITICAL_SYSTEM_INFO_MISSING
Value: 3
The driver couldn't obtain some non-critical information from the system. ADS can still function but the user's experience might be impacted.
DXGK_DISPLAYMUX_RUNTIME_STATUS_CRITICAL_SYSTEM_INFO_MISSING
Value: 4
The driver couldn't obtain some critical information from the system. ADS can still function but the user's experience might be impacted.
