Description

This extension extends SurfaceCapabilities2KHR, providing applications a way to query whether swapchains can be created with the SWAPCHAIN_CREATE_PROTECTED_BIT_KHR flag set.

Vulkan 1.1 added (optional) support for protect memory and protected resources including buffers (BUFFER_CREATE_PROTECTED_BIT), images (IMAGE_CREATE_PROTECTED_BIT), and swapchains (SWAPCHAIN_CREATE_PROTECTED_BIT_KHR). However, on implementations which support multiple windowing systems, not all window systems may be able to provide a protected display path.

This extension provides a way to query if a protected swapchain created for a surface (and thus a specific windowing system) can be displayed on screen. It extends the existing SurfaceCapabilities2KHR structure with a new SurfaceProtectedCapabilitiesKHR structure from which the application can obtain information about support for protected swapchain creation through getPhysicalDeviceSurfaceCapabilities2KHR.

VkSurfaceProtectedCapabilitiesKHR - Structure describing capability of a surface to be protected

Description

If the VK_GOOGLE_surfaceless_query extension is enabled, the value returned in supportsProtected will be identical for every valid surface created on this physical device, and so in the getPhysicalDeviceSurfaceCapabilities2KHR call, PhysicalDeviceSurfaceInfo2KHR::surface can be NULL_HANDLE. In that case, the contents of SurfaceCapabilities2KHR::surfaceCapabilities as well as any other structure chained to it will be undefined.
