Windows Driver Kit DDI reference (ne-d3dkmdt-dxgk_displaymux_runtime_status)

Description

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

Constants

`DXGK_DISPLAYMUX_RUNTIME_STATUS_UNINITIALIZED:0`

A variable of this enumeration type hasn't yet been assigned a meaningful value.

`DXGK_DISPLAYMUX_RUNTIME_STATUS_OK:1`

The GPU supports ADS and the driver has obtained required information from the system.

`DXGK_DISPLAYMUX_RUNTIME_STATUS_NO_GPU_SUPPORT:2`

The GPU doesn't support ADS.

`DXGK_DISPLAYMUX_RUNTIME_STATUS_NON_CRITICAL_SYSTEM_INFO_MISSING: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:4`

The driver couldn't obtain some critical information from the system. ADS can still function but the user's experience might be impacted.
