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)

In the beginning was the lambda, and the lambda was with Emacs, and Emacs
was the lambda.
