VkMemoryOverallocationBehaviorAMD(3)
C Specification
Possible values for
VkDeviceMemoryOverallocationCreateInfoAMD::overallocationBehavior
include:
// Provided by VK_AMD_memory_overallocation_behavior
typedef enum VkMemoryOverallocationBehaviorAMD {
VK_MEMORY_OVERALLOCATION_BEHAVIOR_DEFAULT_AMD = 0,
VK_MEMORY_OVERALLOCATION_BEHAVIOR_ALLOWED_AMD = 1,
VK_MEMORY_OVERALLOCATION_BEHAVIOR_DISALLOWED_AMD = 2,
} VkMemoryOverallocationBehaviorAMD;Description
-
VK_MEMORY_OVERALLOCATION_BEHAVIOR_DEFAULT_AMD lets the implementation decide if overallocation is 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.
