From 09854a4596019ddb3bb315b8836b5c88e718cdc7 Mon Sep 17 00:00:00 2001 From: Ellie Hermaszewska Date: Tue, 12 Sep 2023 11:13:11 +0800 Subject: Add Mesh and Task shader support to GFX (#3190) * Bump vulkan headers Also just use vulkan-headers as a submodule * Add drawMeshTasks to gfx graphics pipelines * Add DispatchMesh overload with no payload, with GLSL intrinsic * Require spirv 1.4 for mesh shaders * Add vulkan mesh shader feature discovery * Add mesh shader stage bits to vk-util * Add mesh and task shader support to render-test * Add mesh and task tests * Preserve "payload" specifier in task shaders * Add mesh shader pipeline support to gfx * Add TODO * Add numThreads attribute for amplification stage * Add payload to task shader test * Drop dependency on d3dx12 * Allow passing payloads from task to mesh shaders * regenerate vs projects * check DispatchMesh name correctly * Add mesh shader tests to failing tests * Detect wave-ops feature on vulkan * Add fuse-product to expected failures This fails because the global varaible `count` is not initialized * Add required extension to WaveMaskMatch SPIR-V impl * Remove meshShader member from pipeline desc * Identify mesh shader support on d3d12 --- tools/gfx/d3d12/d3d12-device.cpp | 12 ++++++++++++ 1 file changed, 12 insertions(+) (limited to 'tools/gfx/d3d12/d3d12-device.cpp') diff --git a/tools/gfx/d3d12/d3d12-device.cpp b/tools/gfx/d3d12/d3d12-device.cpp index 3f62c2d5c..ca624b99f 100644 --- a/tools/gfx/d3d12/d3d12-device.cpp +++ b/tools/gfx/d3d12/d3d12-device.cpp @@ -783,6 +783,18 @@ Result DeviceImpl::initialize(const Desc& desc) } } } + // Check mesh shader support + { + D3D12_FEATURE_DATA_D3D12_OPTIONS7 options; + if (SLANG_SUCCEEDED(m_device->CheckFeatureSupport( + D3D12_FEATURE_D3D12_OPTIONS7, &options, sizeof(options)))) + { + if (options.MeshShaderTier >= D3D12_MESH_SHADER_TIER_1) + { + m_features.add("mesh-shader"); + } + } + } } m_desc = desc; -- cgit v1.2.3
