Description Bruno Damour 2022-12-05 17:22:39 UTC

Hello,

I tried to setup VF interfaces using SR-IOV in intel-ix-kmod, it kind of works but as soon as I create the SF interfaces, the connection on the primary interfaces hangs.
Hardware : X520-DA1
OS : FreeBSD-13.1

I have in my iov config file (/etc/iovctl-ix0.conf) :

<pre>
PF {
    device: ix0;
    num_vfs: 3;
}
DEFAULT {
    passthrough: false;
    allow-set-mac: true;
    allow-promisc: true;
}
VF-1 {
    passthrough: true;
}
VF-2 {
    passthrough: true;
}
</pre>

I start creating VFs with :

<pre>
iovctl -C -f /etc/iovctl-ix0.conf
</pre>

and get one ixv0 plus two ppt (which is expected), but the connection i lost on ix0.

No messages in log file except initialization messages :
<pre>

Any ideas (bug in driver, too cheap hardware ?).

NB : I tried with different versions of the intel driver (compiled manually), the last one is 3.3.32, but the symptoms remain the same.

Thanks

Bruno

Comment 1 Bruno Damour 2023-06-17 20:44:39 UTC

Hello,
I tried with the updated port of intel-ix-kmod and there is a progress but still failing for me, maybe misonfiguration on my side ?
If I set SR-iov in rc.conf it starts and I see in the logs of my dhcp server that it requests an ip, and the dhcp sends an offer, but it doesn’t seem to be received (dhclient reports no offers received) so connectivity still seems partial (one way ?), so that is still failing to work properly.

I forgot to say I have upgraded to 13.2 since my first report. Otherwise is the configuration the same.

Comment 3 Bruno Damour 2023-06-21 13:00:55 UTC

Some logs to document :

/etc/rc.conf
#ifconfig_ix0="dhcp up"
#ifconfig_ix0_ipv6="inet6 accept_rtadv"
ifconfig_ixv0="dhcp up"
ifconfig_ixv0_ipv6="inet6 accept_rtadv"
iovctl_files="/etc/iovctl-ix0.conf"

Can you try with https://reviews.freebsd.org/D19279? You will need to adjust paths.

Hello,

I looked at this patch but it seems quite old.

It seems to already have been applied in the current version (ix-3.3.33), and there has been some refactoring since.

In the current source I see :

if_sr_iov.c line 384:

	vf->flags |= IXGBE_VF_CTS;

	resp[0] = IXGBE_VF_RESET | ack;
	bcopy(vf->ether_addr, &resp[1], ETHER_ADDR_LEN);
	resp[3] = hw->mac.mc_filter_type;
	ixgbe_write_mbx(hw, resp, IXGBE_VF_PERMADDR_MSG_LEN, vf->pool);

if_sr_iov.c line 716:

	ixgbe_init_mbx_params_pf(&sc->hw);

	/* set the SRIOV flag now as it's needed
	 * by ixgbe_init_locked() */
	sc->feat_en |= IXGBE_FEATURE_SRIOV;
	ixgbe_init_locked(sc);

Hello,
Tried with the newer updated driver ix-3.3.35, no luck, the symptoms remain the same...
