DRED GetAutoBreadcrumbsOutput() gives hresult DXGI_ERROR_UNSUPPORTED

Question

Naively copy pasting from https://devblogs.microsoft.com/directx/dred/

winrt::com_ptr<ID3D12DeviceRemovedExtendedDataSettings> pDredSettings;
winrt::check_hresult(D3D12GetDebugInterface(IID_PPV_ARGS(&pDredSettings)));
pDredSettings->SetAutoBreadcrumbsEnablement(D3D12_DRED_ENABLEMENT_FORCED_ON);
pDredSettings->SetPageFaultEnablement(D3D12_DRED_ENABLEMENT_FORCED_ON);

winrt::com_ptr<ID3D12DeviceRemovedExtendedData> pDred;
winrt::check_hresult(device->QueryInterface(IID_PPV_ARGS(&pDred)));

D3D12_DRED_AUTO_BREADCRUMBS_OUTPUT DredAutoBreadcrumbsOutput;
D3D12_DRED_PAGE_FAULT_OUTPUT DredPageFaultOutput;
    
winrt::check_hresult(pDred->GetAutoBreadcrumbsOutput(&DredAutoBreadcrumbsOutput)); // error
//  0x887A0004 : 'The specified device interface or feature level is not supported on this system.'.

Any ideas?

Sigh. Once again I debugged what was causing a non-zero hresult when it was explained in the docs.

I didn't read the fine print

DRED settings must be configure prior to creating a D3D12 Device. Use D3D12GetDebugInterface to get an interface to the ID3D12DeviceRemovedExtendedDataSettings object.

Also GetAutoBreadcrumbsOutput() will error with DXGI_ERROR_NOT_CURRENTLY_AVAILABLE unless ID3D12::GetDeviceRemovedReason() is returning DXGI_ERROR_DEVICE_HUNG so I recommend adding the following line before calling:

_ASSERTE(device->GetDeviceRemovedReason() == DXGI_ERROR_DEVICE_HUNG);
