C Specification

The VkPhysicalDevicePageableDeviceLocalMemoryFeaturesEXT structure is defined as:

// Provided by VK_EXT_pageable_device_local_memory
typedef struct VkPhysicalDevicePageableDeviceLocalMemoryFeaturesEXT {
    VkStructureType    sType;
    void*              pNext;
    VkBool32           pageableDeviceLocalMemory;
} VkPhysicalDevicePageableDeviceLocalMemoryFeaturesEXT;

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.

  • pageableDeviceLocalMemory indicates that the implementation supports pageable device-local memory and may transparently move device-local memory allocations to host-local memory to better share device-local memory with other applications.

Description

If the VkPhysicalDevicePageableDeviceLocalMemoryFeaturesEXT 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. VkPhysicalDevicePageableDeviceLocalMemoryFeaturesEXT can also be used in the pNext chain of VkDeviceCreateInfo to selectively enable these features.

Valid Usage (Implicit)

  • VUID-VkPhysicalDevicePageableDeviceLocalMemoryFeaturesEXT-sType-sType
    sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_PAGEABLE_DEVICE_LOCAL_MEMORY_FEATURES_EXT
