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.

New Enum Constants

- type KHR_SURFACE_PROTECTED_CAPABILITIES_SPEC_VERSION = 1
- pattern KHR_SURFACE_PROTECTED_CAPABILITIES_SPEC_VERSION :: forall a. Integral a => a
- type KHR_SURFACE_PROTECTED_CAPABILITIES_EXTENSION_NAME = "VK_KHR_surface_protected_capabilities"
- pattern KHR_SURFACE_PROTECTED_CAPABILITIES_EXTENSION_NAME :: forall a. (Eq a, IsString a) => a
Documentation
data SurfaceProtectedCapabilitiesKHR Source #
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 struct chained to it will be undefined.
