From: Jia He <[email protected]> We watched a rte panic of mbuf_autotest in our qualcomm arm64 server (Amberwing) due to a possible race condition. To fix this race condition, rmb() is needed to add between the 2 loads.
Already fuctionally tested on the machines as follows: - on X86 - on arm64 --- Changelog V6: improve the text description and fix the checkpatch warnings V5: split it into 2 patchset due to the milestone concerns, this is the 1st one V4: split into small patches V3: arch specific implementation for enqueue/dequeue barrier V2: let users choose whether using load_acquire/store_release V1: rte_smp_rmb() between 2 loads Jia He (1): ring: guarantee load/load order in enqueue and dequeue lib/librte_ring/rte_ring.h | 12 ++++++++++++ 1 file changed, 12 insertions(+) -- 2.7.4
