DXGK_DIAG_DISPLAY_MODE_SET enumeration (dispmprt.h)

DXGK_DIAG_DISPLAY_MODE_SET provides a driver's last mode set state to the operating system (OS) when it is gathering nonintrusive display diagnostic information.

Syntax

typedef enum _DXGK_DIAG_DISPLAY_MODE_SET {
  DXGK_DIAG_DISPLAY_MODE_SET_UNINITIALIZED,
  DXGK_DIAG_DISPLAY_MODE_SET_NO,
  DXGK_DIAG_DISPLAY_MODE_SET_YES
} DXGK_DIAG_DISPLAY_MODE_SET;

Constants

DXGK_DIAG_DISPLAY_MODE_SET_UNINITIALIZED Reserved for OS use during diagnostic initialization.
DXGK_DIAG_DISPLAY_MODE_SET_NO The driver did not complete the last mode set successfully.
DXGK_DIAG_DISPLAY_MODE_SET_YES The driver completed the last mode set successfully.

Remarks

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

While the OS tracks whether the last Set mode call succeeded, DXGK_DIAG_DISPLAY_MODE_SET provides the driver's state regarding mode set on a given target to compare against the OS state. For the OS, a mode set operation mainly consists of a SetTimings DDI call. However, for drivers, a mode set usually means multiple internal operations to set the hardware timings correctly. The OS can use DXGK_DIAG_DISPLAY_MODE_SET to determine the overall driver state for mode set and if it is considered successful.
