C Specification

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.

// Provided by VK_AMD_memory_overallocation_behavior
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.


Valid Usage (Implicit)
  • VUID-VkDeviceMemoryOverallocationCreateInfoAMD-sType-sType

  • VUID-VkDeviceMemoryOverallocationCreateInfoAMD-overallocationBehavior-parameter
    overallocationBehavior must be a valid VkMemoryOverallocationBehaviorAMD value
