# VkPhysicalDevicePageableDeviceLocalMemoryFeaturesEXT(3) Manual Page

## Name

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

Loading… please wait.

## 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`
