DXGK_SETVIDPNSOURCEADDRESS_INPUT_FLAGS structure (d3dkmddi.h)

  • Article

The DXGK_SETVIDPNSOURCEADDRESS_INPUT_FLAGS structure contains the set of flags needed to set the VidPN source address.

Syntax

typedef struct _DXGK_SETVIDPNSOURCEADDRESS_INPUT_FLAGS {
  union {
    struct {
      UINT FlipStereo : 1;
      UINT FlipStereoTemporaryMono : 1;
      UINT FlipStereoPreferRight : 1;
      UINT RetryAtLowerIrql : 1;
      UINT Reserved : 28;
    };
    UINT Value;
  };
} DXGK_SETVIDPNSOURCEADDRESS_INPUT_FLAGS;

Members

FlipStereo

Specifies whether the driver flips both the left and right images of a stereo allocation.

If the FlipOnNextVSync member of the DXGK_PLANE_SPECIFIC_INPUT_FLAGS structure is set, the driver completes the flip to the left image on the next VSync and then completes the flip to the right image on the following VSync.

If the FlipImmediate member of DXGK_PLANE_SPECIFIC_INPUT_FLAGS is set, the driver immediately starts to scan out from the new allocation. For example, if the driver was scanning a right image, it starts the new scan from the same relative offset in the right image of the new allocation.

The FlipStereo and FlipStereoTemporaryMono members cannot both be set at the same time.

FlipStereoTemporaryMono

Specifies whether the driver uses the left image of a stereo allocation for the right and left portions of a stereo frame. The driver performs the same present operation as with FlipStereo, except that it scans out only from the left image to produce both images of a stereo frame.

This member should be set only if the driver reports support for this option in the current display mode by setting the Type member of the D3DKMDT_VIDPN_SOURCE_MODE structure to D3DKMDT_RMT_GRAPHICS_STEREO_ADVANCED_SCAN.

FlipStereoPreferRight

Specifies that when the driver clones a stereo primary allocation to a mono monitor, it uses the right image.

The FlipStereoTemporaryMono and FlipStereoPreferRight members cannot both be set at the same time.

RetryAtLowerIrql

The scheduler sets this flag if the call is made at PASSIVE_LEVEL. Hence, the driver can perform hardware changes in this call.

Reserved

This member is reserved and should be set to zero. Setting this member to zero is equivalent to setting the remaining 28 bits (0xFFFFFFF8) of the 32-bit Value member to zeros.

Value

An alternative way to access the bits.
