CmdBarrier

Fully qualified name: cupva::CmdBarrier

Defined in src/host/cpp_api/include/cupva_host.hpp

class CmdBarrier : public cupva::BaseCmd

Barrier is the command barrier of the Commands in a Stream.

Any Command submitted after the Barrier can begin execution only after all Command instances submitted before the Barrier complete the execution.

Public Functions

CmdBarrier() noexcept

Construct a new Barrier object.

Usage considerations

• Allowed context for the API call

  • Thread-safe: No

• API group

  • Init: No

  • Runtime: Yes

  • De-Init: No

~CmdBarrier() noexcept

Destroy the Barrier object.

Usage considerations

  • Thread-safe: No

• API group

  • Init: No

  • Runtime: Yes

  • De-Init: No

CmdBarrier(CmdBarrier &&obj) noexcept

Move constructor.

Usage considerations

  • Thread-safe: No

• API group

  • Init: No

  • Runtime: Yes

  • De-Init: No

CmdBarrier &operator=(CmdBarrier &&obj) & noexcept

Move assignment.

Usage considerations

  • Thread-safe: No

• API group

  • Init: No

  • Runtime: Yes

  • De-Init: No

CmdBarrier(CmdBarrier const&) = delete

CmdBarrier &operator=(CmdBarrier const&) & = delete

void finalize()

Destroy the resources created by a BaseCmd object.

This method is exposed to allow fine-grained control over error handling.

During destruction of the object, this method will be called but the destructor must not propagate exceptions. To handle exceptions, manually invoke this method prior to object destruction.

Usage considerations

• Allowed context for the API call

  • Thread-safe: No

• API group

  • Init: No

  • Runtime: No

  • De-Init: Yes

Throws:

• cupva::Exception(DriverAPIError) – if driver returns error during de-initialization of mapped/pinned memory

• cupva::Exception(NotAllowedInOperationalState) – if called when NVIDIA DRIVE OS VM state is “Operational”
