VkPhysicalDeviceMapMemoryPlacedFeaturesEXT(3)

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
