Description

VK_KHR_maintenance3 adds a collection of minor features that were intentionally left out or overlooked from the original Vulkan 1.0 release.

The new features are as follows:

• A limit on the maximum number of descriptors that are supported in a single descriptor set layout. Some implementations have a limit on the total size of descriptors in a set, which cannot be expressed in terms of the limits in Vulkan 1.0.
• A limit on the maximum size of a single memory allocation. Some platforms have kernel interfaces that limit the maximum size of an allocation.

Promotion to Vulkan 1.1

All functionality in this extension is included in core Vulkan 1.1, with the KHR suffix omitted. The original type, enum and command names are still available as aliases of the core functionality.

New Commands

• getDescriptorSetLayoutSupportKHR

New Structures

• DescriptorSetLayoutSupportKHR

• Extending PhysicalDeviceProperties2:

  • PhysicalDeviceMaintenance3PropertiesKHR

New Enum Constants

• KHR_MAINTENANCE3_EXTENSION_NAME

• KHR_MAINTENANCE3_SPEC_VERSION
• KHR_MAINTENANCE_3_EXTENSION_NAME
• KHR_MAINTENANCE_3_SPEC_VERSION

• Extending StructureType:

  • STRUCTURE_TYPE_DESCRIPTOR_SET_LAYOUT_SUPPORT_KHR
  • STRUCTURE_TYPE_PHYSICAL_DEVICE_MAINTENANCE_3_PROPERTIES_KHR

Version History

• Revision 1, 2017-08-22
