DXGK_DIAG_GETDISPLAYSTATE_SUBSTATUS_FLAGS enumeration (dispmprt.h)

  • Article

DXGK_DIAG_GETDISPLAYSTATE_SUBSTATUS_FLAGS specifies the substatus for per target diagnostic data collection.

Syntax

typedef enum _DXGK_DIAG_GETDISPLAYSTATE_SUBSTATUS_FLAGS {
  DXGK_DIAG_GETDISPLAYSTATE_SUCCESS,
  DXGK_DIAG_GETDISPLAYSTATE_CAUSED_GLITCH,
  DXGK_DIAG_GETDISPLAYSTATE_CHANGED_DISPLAY_STATE,
  DXGK_DIAG_GETDISPLAYSTATE_MONITOR_NOT_CONNECTED,
  DXGK_DIAG_GETDISPLAYSTATE_TIMEOUT,
  DXGK_DIAG_GETDISPLAYSTATE_ERROR_HARDWARE,
  DXGK_DIAG_GETDISPLAYSTATE_ERROR_DRIVER,
  DXGK_DIAG_GETDISPLAYSTATE_VIDPNTARGETID_NOT_FOUND
} DXGK_DIAG_GETDISPLAYSTATE_SUBSTATUS_FLAGS;

Constants

 
DXGK_DIAG_GETDISPLAYSTATE_SUCCESS
No errors occurred on the given vidpntarget while collecting the diagnostic information.
DXGK_DIAG_GETDISPLAYSTATE_CAUSED_GLITCH
A user-visible glitch occurred on a given vidpntarget while collecting the diagnostic information.
DXGK_DIAG_GETDISPLAYSTATE_CHANGED_DISPLAY_STATE
A display state change (hardware or software) was caused while collecting the diagnostic information on the given vidpntarget.
DXGK_DIAG_GETDISPLAYSTATE_MONITOR_NOT_CONNECTED
No monitor was detected as connected on the given vidpntarget.
DXGK_DIAG_GETDISPLAYSTATE_TIMEOUT
The driver hit a timeout while collecting the diagnostic information on a given vidpntarget.
DXGK_DIAG_GETDISPLAYSTATE_ERROR_HARDWARE
The driver hit a hardware error while collecting the diagnostic information on a given vidpntarget.
DXGK_DIAG_GETDISPLAYSTATE_ERROR_DRIVER
The driver hit a software error while collecting the diagnostic information on a given vidpntarget.
DXGK_DIAG_GETDISPLAYSTATE_VIDPNTARGETID_NOT_FOUND
The driver did not find the VidPnTargetId provided by the OS in the DDI call.

Remarks

The DXGK_DIAG_GETDISPLAYSTATE_SUBSTATUS_FLAGS enumeration is a member of the DXGK_DISPLAYSTATE_NONINTRUSIVE structure. It is used while gathering display diagnostic information via calls to DxgkDdiGetDisplayStateNonIntrusive.

In rare cases where a platform-specific implementation requires the driver to carry out intrusive operations during a call to DxgkDdiGetDisplayStateNonIntrusive, the driver should carry out these operations but must set DXGK_DIAG_GETDISPLAYSTATE_SUBSTATUS_FLAGS to DXGK_DIAG_GETDISPLAYSTATE_CAUSED_GLITCH or DXGK_DIAG_GETDISPLAYSTATE_CHANGED_DISPLAY_STATE accordingly. The OS can use this information to decide whether to call the DDI for error scenarios only on a given system.

The substatus information helps the driver succeed the overall DxgkDdiGetDisplayStateNonIntrusive call even if there were failure or errors on some of the targets.
