VkPhysicalDeviceMapMemoryPlacedFeaturesEXT(3)

# VkPhysicalDeviceMapMemoryPlacedFeaturesEXT(3) Manual Page

## Name

VkPhysicalDeviceMapMemoryPlacedFeaturesEXT - Structure describing placed memory map features that can be supported by an implementation

## C Specification

The `VkPhysicalDeviceMapMemoryPlacedFeaturesEXT` structure is defined as:

    // Provided by VK_EXT_map_memory_placed
    typedef struct VkPhysicalDeviceMapMemoryPlacedFeaturesEXT {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           memoryMapPlaced;
        VkBool32           memoryMapRangePlaced;
        VkBool32           memoryUnmapReserve;
    } VkPhysicalDeviceMapMemoryPlacedFeaturesEXT;

## Members

This structure describes the following features:

- `memoryMapPlaced` indicates that the implementation supports placing memory maps at application-specified virtual addresses.

- `memoryMapRangePlaced` indicates that the implementation supports placing memory maps of a subrange of a memory object at application-specified virtual addresses.

- `memoryUnmapReserve` indicates that the implementation supports leaving the memory range reserved when unmapping a memory object.

## Description

If the `VkPhysicalDeviceMapMemoryPlacedFeaturesEXT` 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 `VkPhysicalDeviceMapMemoryPlacedFeaturesEXT`, 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-VkPhysicalDeviceMapMemoryPlacedFeaturesEXT-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_MAP_MEMORY_PLACED_FEATURES_EXT
