C Specification
Possible values for VkDeviceMemoryOverallocationCreateInfoAMD::overallocationBehavior include:
typedef enum VkMemoryOverallocationBehaviorAMD {
VK_MEMORY_OVERALLOCATION_BEHAVIOR_DEFAULT_AMD = 0,
VK_MEMORY_OVERALLOCATION_BEHAVIOR_ALLOWED_AMD = 1,
VK_MEMORY_OVERALLOCATION_BEHAVIOR_DISALLOWED_AMD = 2,
VK_MEMORY_OVERALLOCATION_BEHAVIOR_MAX_ENUM_AMD = 0x7FFFFFFF
} VkMemoryOverallocationBehaviorAMD;
Description
-
VK_MEMORY_OVERALLOCATION_BEHAVIOR_DEFAULT_AMD
lets the implementation decide if overallocation should be allowed. -
VK_MEMORY_OVERALLOCATION_BEHAVIOR_ALLOWED_AMD
specifies overallocation is allowed if platform permits. -
VK_MEMORY_OVERALLOCATION_BEHAVIOR_DISALLOWED_AMD
specifies the application is not allowed to allocate device memory beyond the heap sizes reported by VkPhysicalDeviceMemoryProperties. Allocations that are not explicitly made by the application within the scope of the Vulkan instance are not accounted for.
