Hi Yunjian,

                That’s interesting. Is it possible to elaborate the use case or possibly provide the code snippet?

It is possible that it is a synchronization problem due to relaxed memory model that Arm architecture uses. There could be a barrier missing in the code.

Thanks,

Honnappa

Subject: [dpdk-dev][dpdk-users] A problem about memory may not be all-zero allocated by rte_zmalloc_socket()

Hi, all

There's a problem that the memory are allocated by rte_zmalloc_socket()

may not be all-zero on the ARM platform.

However, the x86 platform does not have this problem.

Any ideas ?

Thanks,

Yunjian
