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. 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.
