  • Renamed DispatchMesh launch nodes to simply [Mesh launch nod v0.52|2/9/2024|
  • If [GetWorkGraphMemoryRequirements](#getworkgraphmemoryrequirements) and [D3D12_WORK_GRAPH_MEMORY_REQUIREMENTS](#d3d12_work_graph_memory_requirements) noted that zero is a possible valid size (including zero as the min but nonzero as the max), in which case it is valid for the app to pass null to [SetProgram](#setprogram).
  • In [D3D12_DISPATCH_GRAPH_DESC](#d3d12_dispatch_graph_desc) clarified the resource state required for `[MULTI]_NODE_GPU_INPUT` graph input description that is in GPU memory (basically the same state requirement as the actual record data that the description points to which was already documented).
  • In [Node output limits](#node-output-limits) added constraint that a node can't declare more than 1024 outputs. Not records, but outputs. Fortunately node arrays just count as 1 output, so it is exceedingly unlikely that any application would ever run into the limit.
  • In [D3D12_SET_WORK_GRAPH_DESC](#d3d12_set_work_graph_desc) reduced backing memory alignment from 64KB minimum to 8 byte minimum.
  • In [D3D12_NODE_CPU_INPUT](#d3d12_node_cpu_input) and [D3D12_NODE_GPU_INPUT](#d3d12_node_gpu_input) updated the record address and stride requirement to `max(4,largest scalar member size)` bytes. Stride can also be `0`. The change here is that previously alignments that weren't multiple of 4 were valid. e.g. a uint16 record,2 bytes, requires 4 byte alignment. [GetEntrypointRecordSizeInBytes()](#getentrypointrecordsizeinbytes) reflects this padding on reported record sizes.
  • For generic programs, in the section describing defaults for missing subobjects, under [Missing primitive topology](#missing-primitive_topology), clarified that if it is a mesh shader program, the topology is declared in the shader itself, so a primitive topology subobject isn't needed. If a primitive topology subobject happens to be present, the runtime enforces it matches what the mesh shader declared. This simply matches existing PSO behavior.
  • [Barrier](#barrier) fixes: Uniform control flow only required for `GROUP_SYNC`. `DeviceMemoryBarrier*()` excludes `GROUP_SHARED_MEMORY`. `MemoryTypeFlags` masked for shader stage when `ALL_MEMORY`. Added detailed rules for valid Barrier() use. Fix [DXIL ops](#lowering-barrier) for UAV Handle vs. NodeRecordHandle. Old intrinsics should produce the new DXIL op on SM 6.8, and uses of the new HLSL intrinsic equivalent to the old HLSL intrinsics will map to the existing barrier DXIL op on prior shader models.
    • v0.53|2/22/2024|
  • Cleared out mentions of June 2023 preview ahead of official release.
  • Noted that [Draw nodes](#draw-nodes), [DrawIndexed nodes](#drawindexed-nodes) and related supporting APIs are cut in favor of experimenting with [mesh nodes](#mesh-nodes) only.
    • v0.54|3/1/2024|
  • Now that DXC reports record alignment to the runtime based on the member sizes, added a [GetEntrypointRecordAlignmentInBytes()](#getentrypointrecordalignmentinbytes) method to help apps understand the record alignment rules, as applied to a given entry point's struct definition. No driver impact from this new API. This is a complement to the exisiting [GetEntrypointRecordSizeInBytes()](#getentrypointrecordsizeinbytes) API.
  • Cleaned up the entry record size and alignemnt requirements in [D3D12_NODE_CPU_INPUT](#d3d12_node_cpu_input) and [D3D12_NODE_GPU_INPUT](#d3d12_node_gpu_input) such that they are aligned to largest scalar member size and must be a multiple of 4. The previous definition would have allowed a struct of size 6 bytes to have a stride of 6. To be safe, bumping that to 8. This is reflected in the above mentioned APIs.
  • In [D3D12_STATE_SUBOBJECT_TYPE](#d3d12_state_object_type), the contents of the subobject `D3D12_SATE_SUBOBJECT_TYPE_RASTERIZER` were incorrectly stated as `D3D12_RASTERIZER_DESC`. Corrected this to be the latest version of this desc, `D3D12_RASTERIZER_DESC2`, which is what the runtime was already assuming and passing to the driver. Correspondingly updated the section describing defaults for missing subobjects to define the correct struct type in [Missing RASTERIZER](#missing-rasterizer), where `MultisampleEnable` isn't a member, it is `LineRasterizationMode` instead, defaulting to `D3D12_LINE_RASTERIZATION_MODE_ALIASED`.

  • Added [Helping mesh nodes work better on some hardware](#helping-mesh-nodes-work-better-on-some-hardware). Plus a few related sections linked from there. This is relevant to experimental mesh nodes prototyping, not yet exposed.
  • Minor fixup: Under [Supported shader targets](#supported-shader-targets) for generic programs, there was a TBD on what DXC version would be required to compile non-lib shaders such as vs_* / ps_* targets and have the runtime be able to know the name of the function (so the app isn't forced to give it a name to use it in a generic program). Updated the TBD to DXC version 1.8, the compiler launched alongside the runtime with generic programs support.

    • v1.000|3/11/2023|
  • Bumping version to 1.000 for official release.
    • v1.001|3/13/2024|
  • Fixed broken wording in experimental [Mesh nodes](#mesh-nodes) section. Made it more clear that a shader of node launch "mesh" is basically a hybrid of a broadcasting launch shader and a mesh shader. One point in particular that needed cleaning up is that dispatch grid (fixed or dynamic) works just like with broadcasting launch wrt `SV_DispatchGrid` in record, `[NodeMaxDispatchGrid()]` vs `[NodeDispatchGrid()]` options.
  • Missing const on pointer members of [D3D12_NODE_CPU_INPUT](#d3d12_node_cpu_input) and [D3D12_MULTI_NODE_CPU_INPUT](#d3d12_multi_node_cpu_input). Released headers don't have this fixed yet - will be include at next chance for an update.
    • v1.002|3/21/2024|
  • In [D3D12_STATE_OBJECT_TYPE](#d3d12_state_object_type) clarified what can be in the various state object types. For instance, `COLLECTION` state objects can have shaders but not program definitions like generic pipelines or work graphs. The latter are confined to `EXECUTABLE` state objects, at least for now.
  • Claraified that experimental [D3D12_WORK_GRAPHS_TIER_1_1](#d3d12_work_graphs_tier) implies the device supports `D3D12_MESH_SHADER_TIER_1`.
    • v1.003|3/25/2024|
  • In [shader function attributes](#shader-function-attributes), for `[NodeShareInputOf(nodeID)]`, corrected the semantics around node renaming to match shipped behavior. The text used to say that the specified nodeID is before any node renames, so if the target gets renamed, the sharing connection based on old name stays intact. This was incorrect. Instead, if the node to share from gets renamed, the `[NodeShareInputOf(nodeID)]` attribute can be overridden at the API to point to the new nodeID.
    • v1.004|4/22/2024|
  • In [Barrier](#barrier) and [Lowering Barrier](#lowering-barrier), clarify that barrier translation between old/new DXIL ops depending on shader model is not implemented.
    • +v1.005|4/30/2024|
  • Fixed minor typos in various mesh node DDIs names where version was 0108 but meant to be 0110.
