Presenting Directly to Display Devices.

Vulkan

How i understood , Vulkan API have exclusive mode.
In docs say create instance with extension “VK_KHR_display” or “VK_EXT_KHR_display”.
But in all cases my instance not created.

If i created instance with extension “VK_KHR_swapchain” or “VK_KHR_surface” or “VK_KHR_win32_surface” or “VK_EXT_debug_report”.
Instance created.
But vkGetInstanceProcAddr(engine.instance, “vkGetDisplayModePropertiesKHR”); get me NULL
vkGetInstanceProcAddr(engine.instance, “vkGetPhysicalDeviceDisplayPlanePropertiesKHR”); get me NULL
vkGetInstanceProcAddr(engine.instance, “vkGetPhysicalDeviceDisplayPropertiesKHR”); get me NULL
vkGetInstanceProcAddr(engine.instance, “vkGetDisplayPlaneSupportedDisplaysKHR”); get me NULL
vkGetInstanceProcAddr(engine.instance, “vkCreateDisplayPlaneSurfaceKHR”); get me NULL

If you implementation does not support VK_KHR_display, then you obviously can’t get the pointers to the functions from that extension. Because your implementation doesn’t support it.

Implementations are not required to support VK_KHR_display. And there is no VK_EXT_KHR_display extension at all.

That being said, VK_KHR_display has a dependency on VK_KHR_surface. So if you asked for the display extension and didn’t ask for the surface one, your instance won’t be able to be created even if the implementation allows both.

And how i must do ?
Create instance with two extensions ? VK_KHR_surface and VK_KHR_display.
I try , not created instance. But create instance with one extension VK_KHR_surface

And my device created only with “VK_KHR_swapchain”

All other extensions give me createDevice error.
