Hi
I am trying to initialize the environment for 3 processes and 2 ports. Currently I fail in vmxnet3_dev_start (0).
The exact place is as follows:
/* Activate device by register write */
VMXNET3_WRITE_BAR1_REG(hw, VMXNET3_REG_CMD, VMXNET3_CMD_ACTIVATE_DEV);
status = VMXNET3_READ_BAR1_REG(hw, VMXNET3_REG_CMD);
if (status != 0) { <<<<<<<<<< status == 1 in my case
PMD_INIT_LOG(ERR, "Device activation in %s(): UNSUCCESSFUL", __func__);
return -1;
}
Do you have any idea what might it be ? BTW when I used the same configuration with 2 processes all worked fine.
Thanks,
Yan

Yan,
Do you mean 2/3 processes or 2/3 cores? Can you post the exact cmd you
used? In particular, how many tx/rx queues you used to configure the dev?
vmxnet3 device has some requirement on the number of rx queues (needs to
be a power-of-two) and not sure if that¹s related.
