The VK_KHR_xlib_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 Xlib
client-side library, as well as a query to determine support for rendering via
Xlib.
F.11.2. New Enum Constants
1) Does X11 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 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.
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 presention support query for (Display*, VisualID) pair.
-
Removed "root" parameter from CreateXlibSurfaceKHR(), as it is
redundant when a window on the same screen is specified as well.
-
Added appropriate X errors.
-
Adjusted wording of issue #1 and added agreed upon resolution.
Revision 3, 2015-10-14 (Ian Elliott)
-
Renamed this extension from VK_EXT_KHR_x11_surface to
VK_EXT_KHR_xlib_surface.
Revision 4, 2015-10-26 (Ian Elliott)
-
Renamed from VK_EXT_KHR_xlib_surface to VK_KHR_xlib_surface.
Revision 5, 2015-11-03 (Daniel Rakos)
-
Added allocation callbacks to vkCreateXlibSurfaceKHR.
Revision 6, 2015-11-28 (Daniel Rakos)
-
Updated the surface create function to take a pCreateInfo structure.
