VkDisplaySurfaceCreateInfoKHR

Structure specifying parameters of a newly created display plane surface object

The VkDisplaySurfaceCreateInfoKHR structure is defined as:

typedef struct VkDisplaySurfaceCreateInfoKHR {
    VkStructureType sType;
    const void* pNext;
    VkDisplaySurfaceCreateFlagsKHR flags;
    VkDisplayModeKHR displayMode;
    uint32_t planeIndex;
    uint32_t planeStackIndex;
    VkSurfaceTransformFlagBitsKHR transform;
    float globalAlpha;
    VkDisplayPlaneAlphaFlagBitsKHR alphaMode;
    VkExtent2D imageExtent;
} VkDisplaySurfaceCreateInfoKHR;
  • sType is a VkStructureType value identifying this structure.
  • pNext is NULL or a pointer to a structure extending this structure.
  • flags is reserved for future use, and must be zero.
  • displayMode is a VkDisplayModeKHR handle specifying the mode to use when displaying this surface.
  • planeIndex is the plane on which this surface appears.
  • planeStackIndex is the z-order of the plane.
  • transform is a VkSurfaceTransformFlagBitsKHR value specifying the transformation to apply to images as part of the scanout operation.
  • globalAlpha is the global alpha value. This value is ignored if alphaMode is not VK_DISPLAY_PLANE_ALPHA_GLOBAL_BIT_KHR.
  • alphaMode is a VkDisplayPlaneAlphaFlagBitsKHR value specifying the type of alpha blending to use.
  • imageExtent is the size of the presentable images to use with the surface.

Creating a display surface must not modify the state of the displays, planes, or other resources it names. For example, it must not apply the specified mode to be set on the associated display. Application of display configuration occurs as a side effect of presenting to a display surface.

Valid Usage

VUID-VkDisplaySurfaceCreateInfoKHR-planeIndex-01252

planeIndex must be less than the number of display planes supported by the device as determined by calling vkGetPhysicalDeviceDisplayPlanePropertiesKHR

VUID-VkDisplaySurfaceCreateInfoKHR-planeReorderPossible-01253

If the planeReorderPossible member of the VkDisplayPropertiesKHR structure returned by vkGetPhysicalDeviceDisplayPropertiesKHR for the display corresponding to displayMode is VK_TRUE then planeStackIndex must be less than the number of display planes supported by the device as determined by calling vkGetPhysicalDeviceDisplayPlanePropertiesKHR; otherwise planeStackIndex must equal the currentStackIndex member of VkDisplayPlanePropertiesKHR returned by vkGetPhysicalDeviceDisplayPlanePropertiesKHR for the display plane corresponding to displayMode

VUID-VkDisplaySurfaceCreateInfoKHR-alphaMode-01254

If alphaMode is VK_DISPLAY_PLANE_ALPHA_GLOBAL_BIT_KHR then globalAlpha must be between 0 and 1, inclusive

VUID-VkDisplaySurfaceCreateInfoKHR-alphaMode-01255

alphaMode must be one of the bits present in the supportedAlpha member of VkDisplayPlaneCapabilitiesKHR for the display plane corresponding to displayMode

VUID-VkDisplaySurfaceCreateInfoKHR-transform-06740

transform must be one of the bits present in the supportedTransforms member of VkDisplayPropertiesKHR for the display corresponding to displayMode

VUID-VkDisplaySurfaceCreateInfoKHR-width-01256

The width and height members of imageExtent must be less than or equal to VkPhysicalDeviceLimits::maxImageDimension2D
