[dpdk-users] 82599ES 10-Gigabit NIC can't use timesync?

[Linyih Teng]

Hello,

I'm trying to capture rx/tx timestamp using *rte_eth_timesync_rx/tx_read()*
functions but it always returns EINVAL. Does the* 82599ES* NIC(with
*igb_uio*) support the timesync function to capture Tx/Rx timestamp?

My system and hardware info are below:
linux-headers-5.4.0-72-generic/bionic-updates,bionic-security,now
5.4.0-72.80~18.04.1 amd64
DPDK-20.08
82599ES NIC bind with igb_uio

Thanks,
Lin

Did you call rte_eth_timesync_enable() and pass a valid timespec ?

I would take testpmd as a reference and check it works with
RTE_LIBRTE_IEEE1588 enabled.
