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:
