This extension extends slink:VkSurfaceCapabilities2KHR, providing
|
|
applications a way to query whether swapchains can: be created with the
|
|
ename:VK_SWAPCHAIN_CREATE_PROTECTED_BIT_KHR flag set.
|
|
|
|
Vulkan 1.1 added (optional) support for protect memory and protected
|
|
resources including buffers (ename:VK_BUFFER_CREATE_PROTECTED_BIT), images
|
|
(ename:VK_IMAGE_CREATE_PROTECTED_BIT), and swapchains
|
|
(ename:VK_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 slink:VkSurfaceCapabilities2KHR structure with a new
|
|
slink:VkSurfaceProtectedCapabilitiesKHR structure from which the application
|
|
can: obtain information about support for protected swapchain creation
|
|
through flink:vkGetPhysicalDeviceSurfaceCapabilities2KHR.
