Detailed Description

Copyright (c) Theophilus Eriata. All Rights Reserved.

Flags used to configure Direct3D 12 memory allocation behavior.

These flags guide the D3D12 Memory Allocator (D3D12MA) or custom allocation logic in selecting memory types, strategies, and mapping behavior for D3D12 resources.

Member Enumeration Documentation

◆ Enum

enum xiiD3D12AllocationFlags::Enum : StorageType
Enumerator
Committed 

Allocate dedicated memory for the resource (committed resource with implicit heap).

NeverAllocate 

Fail allocation if no suitable memory is available; do not create new blocks.

WithinBudget 

Create allocation only if additional memory required for it, if any, won't exceed memory budget.

UpperAddress 

Allocation will be created from upper stack in a double stack pool.

CanAlias 

Allocation can alias other allocations. Use with care and proper synchronization.

StrategyMinMemory 

Allocation strategy that chooses smallest possible free range for the allocation to minimize memory usage and fragmentation, possibly at the expense of allocation time.

StrategyMinTime 

Allocation strategy that chooses first suitable free range for the allocation - not necessarily in terms of the smallest offset but the one that is easiest and fastest to find to minimize allocation time, possibly at the expense of allocation quality.

StrategyMinOffset 

Allocation strategy that chooses always the lowest offset in available space.

Default 

No special flags; use default allocation behavior.
