Flags used to configure Direct3D 12 memory heap properties.
◆ Enum
| Enumerator |
|---|
| Shared | Heap can be shared between multiple devices (e.g., for cross-adapter sharing).
|
| DenyBuffers | Heap cannot be used for buffers (e.g., vertex/index buffers).
|
| AllowDisplay | Heap can be used for displayable resources (e.g., swap chain buffers).
|
| SharedCrossAdapter | Heap can be shared across multiple adapters (e.g., for multi-GPU setups).
|
| DenyRenderTargetAndDepthStencilTextures | Heap cannot be used for render target or depth stencil textures.
|
| DenyNonRenderTargetAndDepthStencilTextures | Heap cannot be used for non-render target and non-depth stencil textures (e.g., regular textures).
|
| HardwareProtected | Heap is hardware protected (e.g., for secure video decoding).
|
| AllowWriteWatch | Heap supports write-watch functionality for tracking modified memory pages.
|
| AllowShaderAtomics | Heap supports shader atomic operations (e.g., for UAVs with atomic counters).
|
| CreateNotResident | Heap is created in a non-resident state and must be made resident before use.
|
| CreateNotZeroed | Heap memory is not zero-initialized upon allocation (use with care to avoid uninitialized memory).
|
| ToolsUseManualWriteTracking | Heap is used by tools with manual write tracking; requires explicit synchronization for CPU writes.
|
| AllowOnlyBuffers | Heap can only be used for buffers (combination of DenyBuffers and DenyNonRenderTargetAndDepthStencilTextures).
|
| AllowOnlyNonDisplayableTextures | Heap can only be used for non-displayable textures (combination of DenyBuffers and AllowDisplay).
|
| AllowOnlyDisplayableTextures | Heap can only be used for displayable textures (combination of DenyBuffers and DenyNonRenderTargetAndDepthStencilTextures).
|
| Default | No special flags; heap can be used for any resource type.
