16  `VK_KHR_maintenance3` adds a collection of minor features that were
17  intentionally left out or overlooked from the original Vulkan 1.0 release.
18  
19  The new features are as follows:
20  
21    * A limit on the maximum number of descriptors that are supported in a
22      single descriptor set layout.
23      Some implementations have a limit on the total size of descriptors in a
24      set, which cannot be expressed in terms of the limits in Vulkan 1.0.
25    * A limit on the maximum size of a single memory allocation.
26      Some platforms have kernel interfaces that limit the maximum size of an
27      allocation.
28  
29  === New Object Types
30  
31  None.
32  
33  === New Enum Constants
34  
35    * Extending elink:VkStructureType:
36    ** ename:VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_MAINTENANCE_3_PROPERTIES_KHR
37    ** ename:VK_STRUCTURE_TYPE_DESCRIPTOR_SET_LAYOUT_SUPPORT_KHR
38  
39  === New Enums
40  
41  None.
42  
43  === New Structures
44  
45    * slink:VkPhysicalDeviceMaintenance3PropertiesKHR
46    * slink:VkDescriptorSetLayoutSupportKHR
47  
48  === New Functions
49  
50    * flink:vkGetDescriptorSetLayoutSupportKHR
51  
52  === Promotion to Vulkan 1.1
53  
54  All functionality in this extension is included in core Vulkan 1.1, with the
55  KHR suffix omitted.
56  The original type, enum and command names are still available as aliases of
57  the core functionality.
58  
59  === Issues
60  
61  None.
