The VK_KHR_xcb_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 an X11 Window, using the XCB client-side library, as well as a query to determine support for rendering via XCB.

  • Extending VkStructureType:



1) Does XCB need a way to query for compatibility between a particular physical device and a specific screen? This would be a more general query than vkGetPhysicalDeviceSurfaceSupportKHR: If it returned VK_TRUE, then the physical device could be assumed to support presentation to any window on that screen.

RESOLVED: Yes, this is needed for toolkits that want to create a VkDevice before creating a window. To ensure the query is reliable, it must be made against a particular X visual rather than the screen in general.

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 presentation support query for an (xcb_connection_t*, xcb_visualid_t) pair.

    • Removed “root” parameter from CreateXcbSurfaceKHR(), as it is redundant when a window on the same screen is specified as well.

    • Adjusted wording of issue #1 and added agreed upon resolution.

  • Revision 3, 2015-10-14 (Ian Elliott)

    • Removed “root” parameter from CreateXcbSurfaceKHR() in one more place.

  • Revision 4, 2015-10-26 (Ian Elliott)

    • Renamed from VK_EXT_KHR_xcb_surface to VK_KHR_xcb_surface.

  • Revision 5, 2015-10-23 (Daniel Rakos)

    • Added allocation callbacks to vkCreateXcbSurfaceKHR.

  • Revision 6, 2015-11-28 (Daniel Rakos)

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