rte_eth_dev_configure

[sothy shan]

Hello!

I am trying to use DPDK  ovs (development branch) with DPDK1.7.

There is an error when running ovs_dpdk command.

Error is

PANIC in ovdk_vport_phy_port_init.
Cannot initi NIC port 0 (-22).

Based on my search within code, rte_eth_dev_configure gives an error with
code -22.

My question is that how to debug or print the PMD_DEBUG_TRACE into file or
terminal when running ovs-dpdk?

Second, any clue why rte_eth_dev_configure give an error with code -22?

Thanks for your help.

Best regards
Sothy

Could you try with testpmd?

Which driver are you using?

The default is to print on stdout.

It depends of your driver.
Example: #define IXGBE_ERR_NO_SAN_ADDR_PTR -22

It's more probably -EINVAL without driver dependency.
It means there is a mistake in your configuration.
PMD_DEBUG_TRACE will help you.

I have problem when I try dpdk ovs with DPDK 1.7. DPDK 1.7 alone working
well.

Drive I installed is compiled with T=x86_64-ivshmem-linuxapp-gcc.

I am not sure when I using DPDK ovs, how to debug at DPDK 1.7.0 code. I
guess I need to enable to print PMD_DEBUG_TRACE message. At this point,
DPDK ovs message is only printed.

I too suspect it is problem with port_conf message. Not sure. First I need
to know how to use PMD_DEBUG_TRACE with DPDK_ovs.

You understand my question?

Thanks again

You should enable CONFIG_RTE_LIBRTE_ETHDEV_DEBUG before compiling.

Yes I understand that you should enable debugging and ask for help on the
right mailling list.
If DPDK alone works well, we cannot do anything for you.
