VkPhysicalDeviceMemoryPriorityFeaturesEXT(3)

Name

VkPhysicalDeviceMemoryPriorityFeaturesEXT - Structure describing memory priority features that can be supported by an implementation

C Specification

The VkPhysicalDeviceMemoryPriorityFeaturesEXT structure is defined as:

// Provided by VK_EXT_memory_priority
typedef struct VkPhysicalDeviceMemoryPriorityFeaturesEXT {
    VkStructureType    sType;
    void*              pNext;
    VkBool32           memoryPriority;
} VkPhysicalDeviceMemoryPriorityFeaturesEXT;

Members

This structure describes the following feature:

  • sType is a VkStructureType value identifying this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • memoryPriority indicates that the implementation supports memory priorities specified at memory allocation time via VkMemoryPriorityAllocateInfoEXT.

Description

If the VkPhysicalDeviceMemoryPriorityFeaturesEXT structure is included in the pNext chain of the VkPhysicalDeviceFeatures2 structure passed to vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. If the application wishes to use a VkDevice with any features described by VkPhysicalDeviceMemoryPriorityFeaturesEXT, it must add an instance of the structure, with the desired feature members set to VK_TRUE, to the pNext chain of VkDeviceCreateInfo when creating the VkDevice.

Valid Usage (Implicit)

  • VUID-VkPhysicalDeviceMemoryPriorityFeaturesEXT-sType-sType
    sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_MEMORY_PRIORITY_FEATURES_EXT
