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

|
====
|
|
Version 3 of the spec added a member
|
|
(pname:vulkanMemoryModelAvailabilityVisibilityChains) to
|
|
slink:VkPhysicalDeviceVulkanMemoryModelFeaturesKHR, which is an incompatible
|
|
change from version 2.
