Description

This extension allows applications to control whether devices that expose the VK_KHR_portability_subset extension are included in the results of physical device enumeration. Since devices which support the VK_KHR_portability_subset extension are not fully conformant Vulkan implementations, the Vulkan loader does not report those devices unless the application explicitly asks for them. This prevents applications which may not be aware of non-conformant devices from accidentally using them, as any device which supports the VK_KHR_portability_subset extension mandates that the extension must be enabled if that device is used.

This extension is implemented in the loader.
