Graphics Debugger & Invalid CPU descriptor handle

GMCommand · 2018-10-12T07:25:08

Hi everybody ! I have a problem with the VS Graphics Debugger and a D3D12 desktop application. When I create my depth stencil resource, I create two descriptor heaps, one with HEAP_TYPE_DSV, and one with HEAP_TYPE_CBV_SRV_UAV (to rebuild position from depth map), both calls to CreateDescriptorHeap succeed. Then I create a shader-resource view, and a depth-stencil view. Things go well with and without the debugger, but when I use the graphics debugger, the application crashes stating that the CPU descriptor handles does not refer to a location in a descriptor heap when I call either CreateDepthStencilView or CreateShaderResourceView. Here is my code : { D3D12_DESCRIPTOR_HEAP_DESC heap_desc = {}; heap_desc.NumDescriptors = 1; heap_desc.Type = D3D12_DESCRIPTOR_HEAP_TYPE_CBV_SRV_UAV; heap_desc.Flags = D3D12_DESCRIPTOR_HEAP_FLAG_NONE; ThrowIfFailed(device->CreateDescriptorHeap(&heap_desc, IID_PPV_ARGS(&m_SRVDescriptorHeap))); heap_desc.Type = D3D12_DESCRIPTOR_HEAP_TYPE_DSV; ThrowIfFailed(device->CreateDescriptorHeap(&heap_desc, IID_PPV_ARGS(&m_DSVDescriptorHeap))); } DXGI_FORMAT depth_format = DXGI_FORMAT_D24_UNORM_S8_UINT; DXGI_FORMAT depth_format_SRV = DXGI_FORMAT_R24_UNORM_X8_TYPELESS; D3D12_CLEAR_VALUE depth_clear = {}; depth_clear.Format = depth_format; depth_clear.DepthStencil.Depth = 1.0f; depth_clear.DepthStencil.Stencil = 0; ThrowIfFailed(device->CreateCommittedResource( &CD3DX12_HEAP_PROPERTIES(D3D12_HEAP_TYPE_DEFAULT), D3D12_HEAP_FLAG_NONE, &CD3DX12_RESOURCE_DESC::Tex2D( depth_format, width, height, 1, 0, 1, 0, D3D12_RESOURCE_FLAG_ALLOW_DEPTH_STENCIL), D3D12_RESOURCE_STATE_DEPTH_WRITE, &depth_clear, IID_PPV_ARGS(&m_Resource) )); { D3D12_DEPTH_STENCIL_VIEW_DESC dstencil_desc = {}; dstencil_desc.Format = depth_format; dstencil_desc.ViewDimension = D3D12_DSV_DIMENSION_TEXTURE2D; dstencil_desc.Flags = D3D12_DSV_FLAG_NONE; // this call causes a crash device->CreateDepthStencilView(m_Resource, &dstencil_desc, m_DSVDescriptorHeap->GetCPUDescriptorHandleForHeapStart()); } { D3D12_SHADER_RESOURCE_VIEW_DESC srv_desc = {}; srv_desc.Shader4ComponentMapping = D3D12_DEFAULT_SHADER_4_COMPONENT_MAPPING; srv_desc.Format = depth_format_SRV; srv_desc.ViewDimension = D3D12_SRV_DIMENSION_TEXTURE2D; srv_desc.Texture2D.MipLevels = 1; // this call causes a crash device->CreateShaderResourceView(m_Resource, &srv_desc, m_SRVDescriptorHeap->GetCPUDescriptorHandleForHeapStart()); } This is the message I get from the DebugLayer : D3D12 ERROR: ID3D12Device::CreateShaderResourceView: Specified CPU descriptor handle ptr=0x0000000000008781 does not refer to a location in a descriptor heap. [ EXECUTION ERROR #646: INVALID_DESCRIPTOR_HANDLE] I have no more information with the GPUBasedValidation. The only thing different I noticed with the graphics debugger is that the handle has a much smaller ptr (and always the same) than without it, but I suppose it's only due to the fact that the application is run in some kind of environment with the graphics debugger, right ? PIX gives me the same error (E_PIX_INVALID_DESCRIPTOR_HANDLE). Can anyone help me understand or give me a clue why I have this problem, please :| ? Many Thanks
