When double checking, I saw this commit which justify why rte_eal_cpu_init()
is before eal_parse_args():
http://dpdk.org/browse/dpdk/commit/?id=f563a3727b5dba
If the goal is to move debug lines in cpu_init, you should split
rte_eal_log_early_init() in 2 functions: 1 to detect cores and 1 for debug
summary.
By the way, these are debug logs which should be disabled by default.
