The `VK_KHR_vulkan_memory_model` extension allows use of the
<<memory-model,Vulkan Memory Model>>, which formally defines how to
synchronize memory accesses to the same memory locations performed by
multiple shader invocations.
=== New Enum Constants
* Extending elink:VkStructureType:
** ename:VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_VULKAN_MEMORY_MODEL_FEATURES_KHR
=== New Structures
* slink:VkPhysicalDeviceVulkanMemoryModelFeaturesKHR
[NOTE]
.Note
====
Version 3 of the spec added a member
(pname:vulkanMemoryModelAvailabilityVisibilityChains) to
slink:VkPhysicalDeviceVulkanMemoryModelFeaturesKHR, which is an incompatible
change from version 2.
