That will be yet another check in the fast path in the implementation, I think, for more fine-grained wait scheme. Let application configure the device with RTE_EVENT_DEV_CFG_PER_DEQUEUE_WAIT so that the application can have two different function pointer-based implementation for dequeue function if required. With RTE_EVENT_DEV_CFG_PER_DEQUEUE_WAIT configuration, implicitly MAX_U64 becomes infinite weight as the wait is uint64_t. I can add this info in v3 if required. Jerin > > >
