removeD3D12Device

test::DeviceRemoval test::removeD3D12Device(QRhi *rhi)

Remove the Direct3D 12 device of rhi on purpose.

Takes the device from QRhiD3D12NativeHandles and passes it to removeD3D12Device(void *). A QRhi on another backend, or a null one, gives a DeviceRemoval that says so.

Returns whether the device was removed, and why not.

removeD3D12Device (2)

test::DeviceRemoval test::removeD3D12Device(void *nativeDevice)

Remove the ID3D12Device at nativeDevice on purpose.

Queries ID3D12Device5 and calls RemoveDevice(). The runtime then signals every fence of the device and every later call on it fails with DXGI_ERROR_DEVICE_REMOVED, as after a GPU timeout, but without a reset of the GPU for the whole machine (§GTR-T1). Needs Windows 10 build 20348 or later; on an older build, another OS or a runtime without ID3D12Device5, nothing happens and why says which.

Returns whether the device was removed, and why not.
