Hi Cheng,
I am working on a system which uses fm10k driver.
In my system, I am hitting an error in eth_fm10k_dev_init().
We are waiting for VF to get GLoRT update message once
update_lport_state(hw, hw->mac.dglort_map, 1, 1); is done.
Check goes something like this.
if (hw->mac.type == fm10k_mac_vf) {
int glort_valid = 0;
int i;
for (i = 0; i < MAX_QUERY_GLORT_STATE_TIMES; i++) {
glort_valid = fm10k_glort_valid(hw);
if (glort_valid) {
PMD_INIT_LOG(INFO, "GloRT update took ~%u ms!",
(i * WAIT_GLORT_MSG_US/1000));
break;
}
But we are at times failing to get an update and so initialising fails.
Could you kindly give pointers on what could be possible reasons why
is there no update from PF ?

Krishna Sharma

DPDK doesn't support DPDK PF + DPDK VF case, only kernel PF + DPDK/kernel VF driver case.

fm10k doesn't support DPDK fm10k PF + DPDK fm10k VF case, only kernel fm10k PF + DPDK/kernel
fm10k VF driver case.

We are having kernel fm10k PF + fm10k VF driver. We are getting the
update(glort updated) in all the cases in most of the times.
But randomly, we are seeing this issue in one of VF initialisation.
The frequency of issue is, say 1 in 20 times.

This is DPDK community, kernel driver is not in the scope.
Please turn to kernel community or ask local technical support from Intel.
