Description

This extension allows controlling whether explicit overallocation beyond the device memory heap sizes (reported by PhysicalDeviceMemoryProperties) is allowed or not. Overallocation may lead to performance loss and is not supported for all platforms.

New Structures

• Extending DeviceCreateInfo:

  • DeviceMemoryOverallocationCreateInfoAMD

New Enums

• MemoryOverallocationBehaviorAMD

New Enum Constants

• AMD_MEMORY_OVERALLOCATION_BEHAVIOR_EXTENSION_NAME

• AMD_MEMORY_OVERALLOCATION_BEHAVIOR_SPEC_VERSION

• Extending StructureType:

  • STRUCTURE_TYPE_DEVICE_MEMORY_OVERALLOCATION_CREATE_INFO_AMD

Version History

• Revision 1, 2018-09-19 (Martin Dinkov)

  • Initial draft.

Bundled Patterns

pattern MEMORY_OVERALLOCATION_BEHAVIOR_DEFAULT_AMD :: MemoryOverallocationBehaviorAMD

MEMORY_OVERALLOCATION_BEHAVIOR_DEFAULT_AMD lets the implementation decide if overallocation is allowed.

pattern MEMORY_OVERALLOCATION_BEHAVIOR_ALLOWED_AMD :: MemoryOverallocationBehaviorAMD

MEMORY_OVERALLOCATION_BEHAVIOR_ALLOWED_AMD specifies overallocation is allowed if platform permits.

pattern MEMORY_OVERALLOCATION_BEHAVIOR_DISALLOWED_AMD :: MemoryOverallocationBehaviorAMD

MEMORY_OVERALLOCATION_BEHAVIOR_DISALLOWED_AMD specifies the application is not allowed to allocate device memory beyond the heap sizes reported by PhysicalDeviceMemoryProperties. Allocations that are not explicitly made by the application within the scope of the Vulkan instance are not accounted for.
