Class KHRSurfaceProtectedCapabilities
VkSurfaceCapabilities2KHR
, 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 VkSurfaceCapabilities2KHR
structure with a new VkSurfaceProtectedCapabilitiesKHR
structure from which the application can obtain information about support for protected swapchain creation through GetPhysicalDeviceSurfaceCapabilities2KHR
.
