VkDeviceMemoryOverallocationCreateInfoAMD

To specify whether device memory allocation is allowed beyond the size reported by VkPhysicalDeviceMemoryProperties, add a VkDeviceMemoryOverallocationCreateInfoAMD structure to the pNext chain of the VkDeviceCreateInfo structure. If this structure is not specified, it is as if the VK_MEMORY_OVERALLOCATION_BEHAVIOR_DEFAULT_AMD value is used.

typedef struct VkDeviceMemoryOverallocationCreateInfoAMD {
    VkStructureType sType;
    const void* pNext;
    VkMemoryOverallocationBehaviorAMD overallocationBehavior;
} VkDeviceMemoryOverallocationCreateInfoAMD;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• overallocationBehavior is the desired overallocation behavior.
