"VK_KHR_display" not present!

Vulkan
1

Hello,

I came across a bunch of warnings.

They look like this:

RENDERDOC: [14:18:06] vk_tracelayer.cpp( 310) - Warning - Requested function GetDisplayPlaneSupportedDisplaysKHR but extension VK_KHR_display is not enabled!

The documentation says that the extension “VK_KHR_display” is a extension for the VkInstance. As calling the function “vkEnumerateInstanceExtensionProperties” no VK_KHR_display is returned. Also if I pass in the extension by hand I have no success.
The programm breaks. VkResult is then “VK_ERROR_EXTENSION_NOT_PRESENT”.

Vulkan Version: 1.0.30
Graphics Card: Geforce GTX 1080

Thank’s for help in advance

The documentation says that the extension “VK_KHR_display” is a extension for the VkInstance.

Yes, but that doesn’t mean everyone supports it. Extensions are optional features. If it is not listed via vkEnumerateInstanceExtensionProperties, then it’s not implemented. So you can’t request it, nor can you get pointers to its functions.

In fact, that means I have to live with that warnings?
