VkPhysicalDeviceZeroInitializeDeviceMemoryFeaturesEXT(3)

Name

VkPhysicalDeviceZeroInitializeDeviceMemoryFeaturesEXT - Structure describing whether the implementation supports cleared allocation functionality

C Specification

The VkPhysicalDeviceZeroInitializeDeviceMemoryFeaturesEXT structure is defined as:

// Provided by VK_EXT_zero_initialize_device_memory
typedef struct VkPhysicalDeviceZeroInitializeDeviceMemoryFeaturesEXT {
    VkStructureType    sType;
    void*              pNext;
    VkBool32           zeroInitializeDeviceMemory;
} VkPhysicalDeviceZeroInitializeDeviceMemoryFeaturesEXT;

Members

This structure describes the following features:

  • sType is a VkStructureType value identifying this structure.

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

  • zeroInitializeDeviceMemory indicates that the implementation supports zeroing memory allocations using a user-specified flag.

Description

If the VkPhysicalDeviceZeroInitializeDeviceMemoryFeaturesEXT 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 VkPhysicalDeviceZeroInitializeDeviceMemoryFeaturesEXT, 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-VkPhysicalDeviceZeroInitializeDeviceMemoryFeaturesEXT-sType-sType
    sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_ZERO_INITIALIZE_DEVICE_MEMORY_FEATURES_EXT
