vkGetPhysicalDeviceDisplayPropertiesKHR - Query information about the available displays

Parameters

• PhysicalDevice is a physical device.

• pPropertyCount is a pointer to an integer related to the number of display devices available or queried, as described below.
• pProperties is either NULL or a pointer to an array of DisplayPropertiesKHR structures.

Description

If pProperties is NULL, then the number of display devices available for PhysicalDevice is returned in pPropertyCount. Otherwise, pPropertyCount must point to a variable set by the user to the number of elements in the pProperties array, and on return the variable is overwritten with the number of structures actually written to pProperties. If the value of pPropertyCount is less than the number of display devices for PhysicalDevice, at most pPropertyCount structures will be written. If pPropertyCount is smaller than the number of display devices available for PhysicalDevice, INCOMPLETE will be returned instead of SUCCESS to indicate that not all the available values were returned.

Valid Usage (Implicit)

• PhysicalDevice must be a valid PhysicalDevice handle

• pPropertyCount must be a valid pointer to a uint32_t value
• If the value referenced by pPropertyCount is not 0, and pProperties is not NULL, pProperties must be a valid pointer to an array of pPropertyCount DisplayPropertiesKHR structures

Return Codes

Success

• SUCCESS
• INCOMPLETE

Failure

• ERROR_OUT_OF_HOST_MEMORY
• ERROR_OUT_OF_DEVICE_MEMORY

Parameters

• PhysicalDevice is a physical device.

VkDisplayPropertiesKHR - Structure describing an available display device

Description

Note

For devices which have no natural value to return here, implementations should return the maximum resolution supported.

Note

Persistent presents may have higher latency, and may use less power when the screen content is updated infrequently, or when only a portion of the screen needs to be updated in most frames.

VkDisplayModeParametersKHR - Structure describing display parameters associated with a display mode

Description

Note

For example, a 60Hz display mode would report a refreshRate of 60,000.

Valid Usage

• The width member of visibleRegion must be greater than 0

• The height member of visibleRegion must be greater than 0
• refreshRate must be greater than 0

Valid Usage (Implicit)

VkDisplayPlaneCapabilitiesKHR - Structure describing capabilities of a mode and plane combination

Description

The minimum and maximum position and extent fields describe the implementation limits, if any, as they apply to the specified display mode and plane. Vendors may support displaying a subset of a swapchain’s presentable images on the specified display plane. This is expressed by returning minSrcPosition, maxSrcPosition, minSrcExtent, and maxSrcExtent values that indicate a range of possible positions and sizes may be used to specify the region within the presentable images that source pixels will be read from when creating a swapchain on the specified display mode and plane.

Vendors may also support mapping the presentable images’ content to a subset or superset of the visible region in the specified display mode. This is expressed by returning minDstPosition, maxDstPosition, minDstExtent and maxDstExtent values that indicate a range of possible positions and sizes may be used to describe the region within the display mode that the source pixels will be mapped to.

Other vendors may support only a 1-1 mapping between pixels in the presentable images and the display mode. This may be indicated by returning (0,0) for minSrcPosition, maxSrcPosition, minDstPosition, and maxDstPosition, and (display mode width, display mode height) for minSrcExtent, maxSrcExtent, minDstExtent, and maxDstExtent.

These values indicate the limits of the implementation’s individual fields. Not all combinations of values within the offset and extent ranges returned in DisplayPlaneCapabilitiesKHR are guaranteed to be supported. Presentation requests specifying unsupported combinations may fail.

VkDisplaySurfaceCreateInfoKHR - Structure specifying parameters of a newly created display plane surface object

Description

Note

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

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

• If the planeReorderPossible member of the DisplayPropertiesKHR structure returned by getPhysicalDeviceDisplayPropertiesKHR for the display corresponding to displayMode is TRUE then planeStackIndex must be less than the number of display planes supported by the device as determined by calling getPhysicalDeviceDisplayPlanePropertiesKHR; otherwise planeStackIndex must equal the currentStackIndex member of DisplayPlanePropertiesKHR returned by getPhysicalDeviceDisplayPlanePropertiesKHR for the display plane corresponding to displayMode
• If alphaMode is DISPLAY_PLANE_ALPHA_GLOBAL_BIT_KHR then globalAlpha must be between 0 and 1, inclusive
• alphaMode must be 0 or one of the bits present in the supportedAlpha member of DisplayPlaneCapabilitiesKHR returned by getDisplayPlaneCapabilitiesKHR for the display plane corresponding to displayMode
• The width and height members of imageExtent must be less than the maxImageDimensions2D member of PhysicalDeviceLimits

Valid Usage (Implicit)

• sType must be STRUCTURE_TYPE_DISPLAY_SURFACE_CREATE_INFO_KHR

• pNext must be NULL
• Flags must be 0
• displayMode must be a valid DisplayModeKHR handle

VkSurfaceKHR - Opaque handle to a surface object

Description

The VK_KHR_surface extension declares the SurfaceKHR object, and provides a function for destroying SurfaceKHR objects. Separate platform-specific extensions each provide a function for creating a SurfaceKHR object for the respective platform. From the application’s perspective this is an opaque handle, just like the handles of other Vulkan objects.
