The SPDK app framework spawns one thread per core for each core in the core mask provided in the initialization options (called reactor_mask). Each thread then sits in a tight loop polling queues for incoming events and executing pollers. The implementation is in lib/event/reactor.c. Our app framework implements its own timers, so you don't need to use the DPDK timers. You can just call /** * \brief Register a poller on the given lcore. */ void spdk_poller_register(struct spdk_poller **ppoller, spdk_poller_fn fn, void *arg, uint32_t lcore, uint64_t period_microseconds); and pass it a non-zero period. If you really do need to use a DPDK timer, just register a poller using the above function with a period of 0 and inside the spdk_poller_fn you provide, call rte_timer_manage. > > Regards, > -- Naoki > > _______________________________________________ > SPDK mailing list > SPDK(a)lists.01.org > https://lists.01.org/mailman/listinfo/spdk _______________________________________________ SPDK mailing list SPDK(a)lists.01.org https://lists.01.org/mailman/listinfo/spdk
