_AMPIMP accelerator_view __cdecl Concurrency::direct3d::create_accelerator_view | ( | _In_ IUnknown * | _D3D_device, |
queuing_mode | _Qmode = queuing_mode_automatic |
||
) |
Create a accelerator_view from a D3D device interface pointer.
_D3D_device | The D3D device interface pointer to create the accelerator_view from. |
_Qmode | The queuing_mode to be used for the newly created accelerator_view. This parameter has a default value of queuing_mode_automatic. |
_AMPIMP accelerator_view __cdecl Concurrency::direct3d::create_accelerator_view | ( | accelerator & | _Accelerator, |
bool | _Disable_timeout, | ||
queuing_mode | _Qmode = queuing_mode_automatic |
||
) |
Create and return a new accelerator view on the specified accelerator.
_Accelerator | The accelerator on which the new accelerator_view is to be created. |
_Disable_timeout | A boolean parameter that specifies whether timeout should be disabled for the newly created accelerator_view. This corresponds to the D3D11_CREATE_DEVICE_DISABLE_GPU_TIMEOUT flag for Direct3D device creation and is used to indicate if the operating system should allow workloads that take more than 2 seconds to execute, without resetting the device per the Windows timeout detection and recovery mechanism. Use of this flag is recommended if you need to perform time consuming tasks on the accelerator_view. |
_Qmode | The queuing_mode to be used for the newly created accelerator_view. This parameter has a default value of queuing_mode_automatic. |
Acquire a lock on an accelerator_view for the purpose of safely performing D3D operations on resources shared with the accelerator_view. The accelerator_view and all C++ AMP resources associated with this accelerator_view internally take this lock when performing operations and will block while another thread holds the D3D access lock.
This lock is non-recursive: It is undefined behavior to call this function from a thread that already holds the lock. It is undefined behavior to perform operations on the accelerator_view or any data container associated with the accelerator_view from the thread that holds the D3D access lock.
See also scoped_d3d_access_lock, a RAII-style class for a scope-based D3D access lock.
_Av | The accelerator_view to lock. |
Attempt to acquire the D3D access lock on an accelerator_view without blocking.
_Av | The accelerator_view to lock. |
