The D3DDDI_CREATEHWQUEUEFLAGS structure specifies flags to use when creating a hardware queue.
DisableGpuTimeoutWhen set, indicates to the OS that the hardware queue being created is expected to submit DMA buffers that can take longer than 2 seconds to complete on the GPU, and consequently GPU timeout should be disabled.
NoBroadcastSignalWhen set, indicates to the OS that the hardware queue being created does not have application observable behavior, and it should not participate in D3D12 command queue fence broadcast signal operation. This flag was introduced in Windows 10, version 2004.
NoBroadcastWaitWhen set, indicates to the OS that the hardware queue being created does not have application observable behavior, and it should not be blocked behind in D3D12 command queue fence wait operation. This flag was introduced in Windows 10, version 2004.
NoKmdAccessReserved for system use.
UserModeSubmissionWhen set, indicates to the OS that the hardware queue being created uses the user-mode submission model. Hardware queues created using this flag can't use the regular kernel-mode work submission path and must rely on the doorbell mechanism for work submission on the queue.
NativeProgressFenceWhen set, indicates that the DXGKARG_CREATEHWQUEUE::hHwQueueProgressFence handle points to the driver handle of a native GPU fence object previously created using DxgkDdiCreateNativeFence. For more information, see Native GPU fence objects. Available starting with Windows 11, version 24H2.
TestQueueWhen set, indicates that the hardware queue being created is a test queue for kernel-mode testing. Available starting with Windows 11, version 24H2.
ReservedReserved for system use.
ValueThis value can be used to operate over the structure members collectively.
