Hi,
I have an intel I350-T2 which I use for SR-IOV, however, I am hitting some
rx_dropped on the card when I start increasing traffic. (I have got more
with the same software out of a identical bare metal system)
I am using the Intel igb driver on Centos 7.2 (downloaded from Intel not
the driver installed with Centos), so the RSS parameters amongst others are
availbe to me
This then led me to investigate the interrupts on the tx rx ring buffers
and I noticed that the interface (vfs enabled) only had on tx/rx queue. Its
distributed between This is on the KVM Host
CPU0 CPU1 CPU2 CPU3 CPU4
CPU5 CPU6 CPU7 CPU8
100: 1 33 137 0 0
0 0 0 0 IR-PCI-MSI-edge ens2f1
101: 2224 0 0 6309 178807
0 0 0 0 IR-PCI-MSI-edge ens2f1-TxRx-0
Looking at my standard nic ethernet ports I see 1 rx and 4 rx queues
On the VM I only get one tx one rx queue ( I know all the interrupts are
only using CPU0) but that is defined in our builds.
egrep "CPU|ens11" /proc/interrupts
CPU0 CPU1 CPU2 CPU3 CPU4
CPU5 CPU6 CPU7
34: 715885552 0 0 0 0 0
0 0 0 PCI-MSI-edge ens11-tx-0
35: 559402399 0 0 0 0 0
0 0 0 PCI-MSI-edge ens11-rx-0
I activated RSS in my card, and can set if, however if I use the param
max_vfs=n then it defaults back to to 1 rx 1 tx queue per nic port
[ 392.833410] igb 0000:07:00.0: Using MSI-X interrupts. 1 rx queue(s), 1
tx queue(s)
[ 393.035408] igb 0000:07:00.1: Using MSI-X interrupts. 1 rx queue(s), 1
tx queue(s)
I have been reading some of the dpdk older posts and see that VF RSS is
implemented in some cards, does anybody know if its available in this card
(from reading it only seemed the 10GB cards)
One of my plans aside from trying to create more RSS per VM is to add more
CPUS to the VM that are not isolated so that the rx and tx queues can
distribute their load a bit to see if this helps.
Also is it worth investigating the VMDq options, however I understand this
to be less useful than SR-IOV which works well for me with KVM.
Thanks in advance,
Rolando

It is ignored because people have not read it or are not expert in
this hardware.

Did you consult the datasheet? It says that the VF only supports one queue.

Hi Paul,
No I didn't spot that.
I guess my only option now is 10gb card that supports it.
Thanks.

Hi, sorry the ignored comment was a bit brash.
Its my first time posting, and I didnt see the email I sent come into my
inbox (I guess you don't get them sent to yourself), so I did wonder if it
posted ok. However the list archives showed that it did.
Thanks

Hi,
I have an intel I350-T2 which I use for SR-IOV, however, I am hitting some
rx_dropped on the card when I start increasing traffic. (I have got more
with the same software out of a identical bare metal system)
I am using the Intel igb driver on Centos 7.2 (downloaded from Intel not
the driver installed with Centos), so the RSS parameters amongst others are
availbe to me
This then led me to investigate the interrupts on the tx rx ring buffers
and I noticed that the interface (vfs enabled) only had on tx/rx queue. Its
distributed between This is on the KVM Host
CPU0 CPU1 CPU2 CPU3 CPU4
CPU5 CPU6 CPU7 CPU8
100: 1 33 137 0 0
0 0 0 0 IR-PCI-MSI-edge ens2f1
101: 2224 0 0 6309 178807
0 0 0 0 IR-PCI-MSI-edge ens2f1-TxRx-0
Looking at my standard nic ethernet ports I see 1 rx and 4 rx queues
On the VM I only get one tx one rx queue ( I know all the interrupts are
only using CPU0) but that is defined in our builds.
egrep "CPU|ens11" /proc/interrupts
CPU0 CPU1 CPU2 CPU3 CPU4
CPU5 CPU6 CPU7

0 0 0 PCI-MSI-edge ens11-tx-0
35: 559402399 0 0 0 0 0
0 0 0 PCI-MSI-edge ens11-rx-0
I activated RSS in my card, and can set if, however if I use the param
max_vfs=n then it defaults back to to 1 rx 1 tx queue per nic port
[ 392.833410] igb 0000:07:00.0: Using MSI-X interrupts. 1 rx queue(s), 1
tx queue(s)
[ 393.035408] igb 0000:07:00.1: Using MSI-X interrupts. 1 rx queue(s), 1
tx queue(s)
I have been reading some of the dpdk older posts and see that VF RSS is
implemented in some cards, does anybody know if its available in this card
(from reading it only seemed the 10GB cards)
One of my plans aside from trying to create more RSS per VM is to add more
CPUS to the VM that are not isolated so that the rx and tx queues can
distribute their load a bit to see if this helps.
Also is it worth investigating the VMDq options, however I understand this
to be less useful than SR-IOV which works well for me with KVM.
Thanks in advance,
Rolando
