Hi,
I am using the rte_get_timer_cycles() function for IPv4 packet latency
calculation in dpdk application. I think, it is same on all cores. Can
anyone please correct me if I am wrong?
Note that, I have CONFIG_RTE_LIBEAL_USE_HPET=n in configuration.
Regards,
Chinmaya

it *should* be same but because of invariant-tsc support in latest intel
machines (see if cpuid gives you "0x80000007/edx" which indicates its
presence)
