VkPhysicalDevicePageableDeviceLocalMemoryFeaturesEXT(3)

Name

VkPhysicalDevicePageableDeviceLocalMemoryFeaturesEXT - Structure describing whether the implementation supports pageable device-local memory

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. If the application wishes to use a VkDevice with any features described by VkPhysicalDevicePageableDeviceLocalMemoryFeaturesEXT, 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-VkPhysicalDevicePageableDeviceLocalMemoryFeaturesEXT-sType-sType
sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_PAGEABLE_DEVICE_LOCAL_MEMORY_FEATURES_EXT
