Hi. I've been wondering should I use a release/acquire memory barrier pair in order to be sure that the other thread will see the fully/corrected initialized object passed to it via a dpdk ring or ring itself is a kind of barrier?
Let's say I have a pseudo code: Thread1: obj = alloc(); ... obj initialization ... ??? fence(memory_order_release); ??? rte_ring_sp_enqueue(ring, obj) Thread2: ??? fence(memory_order_acquire); ??? rte_ring_sc_dequeue(ring, obj) Should I use fences in that code? Thanks. -- Alex
