Hi,

I just updated to the new sdk 10.0.14393.33 and if I activate the D3D12 Debug layer D3D12CreateDevice simply fails.

// Enable the D3D12 debug layer
ComPtr< ID3D12Debug > debugController;
if(SUCCEEDED(D3D12GetDebugInterface(IID_PPV_ARGS(&debugController))))
{
	debugController->EnableDebugLayer();
	//ComPtr< ID3D12Debug1 > debugController1;
	//if(FAILED(debugController->QueryInterface(IID_PPV_ARGS(&debugController1))))
	//	throw "Failed to retrieve debug controller";
	//debugController1->SetEnableGPUBasedValidation(true);
}

// Get adapter
ComPtr< IDXGIAdapter1 > dxgiAdapter;
if(FAILED(dxgiFactory->EnumAdapters1(0, &dxgiAdapter)))
	throw "Failed to retrieve default adapter";
if(FAILED(dxgiAdapter.As(&m_adapter)))
	throw "Failed to retrieve adapter";

// Create DirectX12 device
if(FAILED(D3D12CreateDevice(m_adapter.Get(), D3D_FEATURE_LEVEL_12_1, IID_PPV_ARGS(&m_device))))
	if(FAILED(D3D12CreateDevice(m_adapter.Get(), D3D_FEATURE_LEVEL_12_0, IID_PPV_ARGS(&m_device))))
		if(FAILED(D3D12CreateDevice(m_adapter.Get(), D3D_FEATURE_LEVEL_11_1, IID_PPV_ARGS(&m_device))))
			if(FAILED(D3D12CreateDevice(m_adapter.Get(), D3D_FEATURE_LEVEL_11_0, IID_PPV_ARGS(&m_device))))
				throw "Failed to create DirectX12 device";

That used to work with 10.0.10586.0 ...

It's also possible you've got mismatched binaries, between D3D12SDKLayers.dll and D3D12.dll. There was an update (http://forums.directxtech.com/index.php?topic=5775.0) that required changes to the runtime and the debug layer.

In my case it was a missing windows update.

Now, GPU based validation works like a charm on my desktop with an AMD rx480 but crashes on my notebook with a GTX980m.

(The cash happens when I try to create a descriptor heap).

Just a quick question, is it possible that by updating windows it changes the supported level of features and resource binding tiers supported by a given gpu?

I have a gtx980m and since last windows update it reports feature level 11.1 and resource binding tier 1. I am sure this was at least feature level 12 and resource binding tier 2.

My app is not working anymore on my laptop :(

Are you sure you're running on the GTX980m and not an Intel part in your laptop?

Good point. Ill check when I get off work, It tends to revert back to the intel gpu after a driver update.

Yeah, I have been lazy and using the first adapter, I will take some time and enumerate the adapters...

Back to GPU validation, I get this message on my laptop and I am not sure what it means:

(at the "Present" call)

IGIESW ***.exe found in whitelist: NOIGIWHW Game ***.exe found in whitelist: NOD3D12 ERROR: GPU-BASED VALIDATION: Present, Back Buffer state invalid, Incompatible resource state: Resource: 0x0000025FF8FD0A50:'swapchain buffer', Subresource Index: [0], Resource State: D3D12_RESOURCE_STATE_[COMMON|PRESENT](0x0), Required State Bits: D3D12_RESOURCE_STATE_[COMMON|PRESENT](0x0), Draw Count [0], Dispatch Count [0], Command List: <deleted>, Resources used in COPY command lists must start out in the D3D12_RESOURCE_STATE_COMMON state. This includes Resources created in a COPY_SOURCE or COPY_DEST state. [ EXECUTION ERROR #942: GPU_BASED_VALIDATION_INCOMPATIBLE_RESOURCE_STATE]

If I understand correctly, 'swapchain buffer' is in the state "D3D12_RESOURCE_STATE_[COMMON|PRESENT](0x0)" but should be in the "state "D3D12_RESOURCE_STATE_[COMMON|PRESENT](0x0)" o.O ??

Without seeing code it sounds like a Resource Hazard occurred somewhere.Be sure that your states are being recorded by the commandList according to how the corresponding Resources are being used.
