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:
// Provided by VK_VERSION_1_2
typedef struct VkPhysicalDeviceVulkanMemoryModelFeatures {
VkStructureType sType;
void* pNext;
VkBool32 vulkanMemoryModel;
VkBool32 vulkanMemoryModelDeviceScope;
VkBool32 vulkanMemoryModelAvailabilityVisibilityChains;
} VkPhysicalDeviceVulkanMemoryModelFeatures;
or the equivalent
// Provided by VK_KHR_vulkan_memory_model
typedef VkPhysicalDeviceVulkanMemoryModelFeatures VkPhysicalDeviceVulkanMemoryModelFeaturesKHR;
Members
-
sType
is the type of this structure. -
pNext
isNULL
or a pointer to a structure extending this structure.
Description
-
vulkanMemoryModel
indicates whether the Vulkan Memory Model is supported, as defined in Vulkan Memory Model. This also indicates whether shader modules can declare theVulkanMemoryModel
capability. -
vulkanMemoryModelDeviceScope
indicates whether the Vulkan Memory Model can useDevice
scope synchronization. This also indicates whether shader modules can declare theVulkanMemoryModelDeviceScope
capability. -
vulkanMemoryModelAvailabilityVisibilityChains
indicates whether the Vulkan Memory Model can use availability and visibility chains with more than one element.
