VkPhysicalDeviceMapMemoryPlacedFeaturesEXT

The VkPhysicalDeviceMapMemoryPlacedFeaturesEXT structure is defined as:

typedef struct VkPhysicalDeviceMapMemoryPlacedFeaturesEXT {
    VkStructureType sType;
    void* pNext;
    VkBool32 memoryMapPlaced;
    VkBool32 memoryMapRangePlaced;
    VkBool32 memoryUnmapReserve;
} VkPhysicalDeviceMapMemoryPlacedFeaturesEXT;

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.

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