The VK_KHR_wayland_surface extension is an instance extension. It provides a mechanism to create a VkSurfaceKHR object (defined by the VK_KHR_surface extension) that refers to a Wayland wl_surface, as well as a query to determine support for rendering to a Wayland compositor.

New Enum Constants



  • Extending VkStructureType:



1) Does Wayland need a way to query for compatibility between a particular physical device and a specific Wayland display? This would be a more general query than vkGetPhysicalDeviceSurfaceSupportKHR: if the Wayland-specific query returned VK_TRUE for a (VkPhysicalDevice, struct wl_display*) pair, then the physical device could be assumed to support presentation to any VkSurfaceKHR for surfaces on the display.

RESOLVED: Yes. vkGetPhysicalDeviceWaylandPresentationSupportKHR was added to address this issue.

2) Should we require surfaces created with vkCreateWaylandSurfaceKHR to support the VK_PRESENT_MODE_MAILBOX_KHR present mode?

RESOLVED: Yes. Wayland is an inherently mailbox window system and mailbox support is required for some Wayland compositor interactions to work as expected. While handling these interactions may be possible with VK_PRESENT_MODE_FIFO_KHR, it is much more difficult to do without deadlock and requiring all Wayland applications to be able to support implementations which only support VK_PRESENT_MODE_FIFO_KHR would be an onerous restriction on application developers.

Version History

  • Revision 1, 2015-09-23 (Jesse Hall)

    • Initial draft, based on the previous contents of VK_EXT_KHR_swapchain (later renamed VK_EXT_KHR_surface).

  • Revision 2, 2015-10-02 (James Jones)

    • Added vkGetPhysicalDeviceWaylandPresentationSupportKHR() to resolve issue #1.

    • Adjusted wording of issue #1 to match the agreed-upon solution.

    • Renamed "window" parameters to "surface" to match Wayland conventions.

  • Revision 3, 2015-10-26 (Ian Elliott)

    • Renamed from VK_EXT_KHR_wayland_surface to VK_KHR_wayland_surface.

  • Revision 4, 2015-11-03 (Daniel Rakos)

    • Added allocation callbacks to vkCreateWaylandSurfaceKHR.

  • Revision 5, 2015-11-28 (Daniel Rakos)

    • Updated the surface create function to take a pCreateInfo structure.

  • Revision 6, 2017-02-08 (Jason Ekstrand)

    • Added the requirement that implementations support VK_PRESENT_MODE_MAILBOX_KHR.

    • Added wording about interactions between vkQueuePresentKHR and the Wayland requests sent to the compositor.
