Description

VK_EXT_surface_maintenance1 adds a collection of window system integration features that were intentionally left out or overlooked in the original VK_KHR_surface extension.

The new features are as follows:

  • Allow querying number of min/max images from a surface for a particular presentation mode.

  • Allow querying a surface’s scaled presentation capabilities.

  • Allow querying a surface for the set of presentation modes which can be easily switched between without requiring swapchain recreation.

Promotion to VK_KHR_surface_maintenance1

All functionality in this extension is included in VK_KHR_surface_maintenance1, with the suffix changed to KHR. The original type, enum and command names are still available as aliases of the KHR functionality.
