Description
This extension provides new entry points to query device surface
capabilities in a way that can be easily extended by other extensions,
without introducing any further entry points.
This extension can be considered the VK_KHR_surface equivalent of
the VK_KHR_get_physical_device_properties2 extension.
New Enum Constants
-
VK_KHR_GET_SURFACE_CAPABILITIES_2_EXTENSION_NAME -
VK_KHR_GET_SURFACE_CAPABILITIES_2_SPEC_VERSION -
Extending VkStructureType:
-
VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SURFACE_INFO_2_KHR -
VK_STRUCTURE_TYPE_SURFACE_CAPABILITIES_2_KHR -
VK_STRUCTURE_TYPE_SURFACE_FORMAT_2_KHR

Issues
1) What should this extension be named?
RESOLVED: VK_KHR_get_surface_capabilities2.
Other alternatives:
-
VK_KHR_surface2 -
One extension, combining a separate display-specific query extension.
2) Should additional WSI query functions be extended?
RESOLVED:
-
vkGetPhysicalDeviceSurfaceCapabilitiesKHR: Yes. The need for this motivated the extension.
-
vkGetPhysicalDeviceSurfaceSupportKHR: No. Currently only has boolean output. Extensions should instead extend vkGetPhysicalDeviceSurfaceCapabilities2KHR.
-
vkGetPhysicalDeviceSurfacePresentModesKHR: No. Recent discussion concluded this introduced too much variability for applications to deal with. Extensions should instead extend vkGetPhysicalDeviceSurfaceCapabilities2KHR.
-
vkGetPhysicalDeviceXlibPresentationSupportKHR: Not in this extension.
-
vkGetPhysicalDeviceXcbPresentationSupportKHR: Not in this extension.
-
vkGetPhysicalDeviceWaylandPresentationSupportKHR: Not in this extension.
-
vkGetPhysicalDeviceWin32PresentationSupportKHR: Not in this extension.
