C Specification
To query memory model features additionally supported call
vkGetPhysicalDeviceFeatures2 with a
VkPhysicalDeviceVulkanMemoryModelFeatures structure included in the
pNext chain of its pFeatures parameter.
The VkPhysicalDeviceVulkanMemoryModelFeatures structure can also be
included in the pNext chain of a VkDeviceCreateInfo structure,
in which case it controls which additional features are enabled in the
device.
The VkPhysicalDeviceVulkanMemoryModelFeatures structure is defined as:
typedef struct VkPhysicalDeviceVulkanMemoryModelFeatures {
VkStructureType sType;
void* pNext;
VkBool32 vulkanMemoryModel;
VkBool32 vulkanMemoryModelDeviceScope;
VkBool32 vulkanMemoryModelAvailabilityVisibilityChains;
} VkPhysicalDeviceVulkanMemoryModelFeatures;
or the equivalent
typedef VkPhysicalDeviceVulkanMemoryModelFeatures VkPhysicalDeviceVulkanMemoryModelFeaturesKHR;
Members
-
sTypeis the type of this structure. -
pNextisNULLor a pointer to an extension-specific structure.
Description
-
vulkanMemoryModelindicates whether the Vulkan Memory Model is supported, as defined in Vulkan Memory Model. This also indicates whether shader modules can declare theVulkanMemoryModelcapability. -
vulkanMemoryModelDeviceScopeindicates whether the Vulkan Memory Model can useDevicescope synchronization. This also indicates whether shader modules can declare theVulkanMemoryModelDeviceScopecapability. -
vulkanMemoryModelAvailabilityVisibilityChainsindicates whether the Vulkan Memory Model can use availability and visibility chains with more than one element.
