CreateSyncStream

Fully qualified name: cupva_utils::CreateSyncStream

Defined in cupva_host_utils.hpp

cupva::Stream cupva_utils::CreateSyncStream(

cupva::EngineType absEngine = cupva::EngineType::PVA0,

cupva::AffinityType vpuAffinity = cupva::AffinityType::VPU_ANY,

)

Construct a new sync Stream object.

A cupva::Stream which is created via this method will implicitly synchronize all submissions with the host-side CPU. Synchronization will occur before returning from the submit() method. This can be useful for debugging purposes.
