[dpdk-dev] Queries on DPDK working with XL710 intel NIC

[dpdk-dev] Queries on DPDK working with XL710 intel NIC

[Nissim Nisimov]

Hi all,

I am trying to work with intel XL710 40GIG NIC but for some reason when trying to load it via dpdk I am getting the following error:


EAL: PCI device 0000:21:00.1 on NUMA socket 1
EAL:   probe driver: 8086:1583 rte_i40e_pmd
EAL:   PCI memory mapped at 0x7fff939f9000
EAL:   PCI memory mapped at 0x7fffd54b8000
EAL: Error - exiting with code: 1
  Cause: Requested device 0000:21:00.1 cannot be used

It seems that the "problematic" functions is i40e_aq_get_firmware_version() in the following line:
status = i40e_asq_send_command(hw, &desc, NULL, 0, cmd_details);
                (gdb) p status
$3 = I40E_ERR_ADMIN_QUEUE_TIMEOUT


I did read in another mail thread (attached below) that this might be a firmware issue so i upgraded my NIC firmware version to latest but still not able to get it work:

root@lagavulin:~# ethtool -i eth24
driver: i40e
version: 1.2.37
firmware-version: f4.33.31377 a1.2 n4.42 e1932
bus-info: 0000:21:00.1
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes


any idea why I still see the issue?

thanks!
Nissim



Hi Yan



Please tell me what version of firmware are you using? If it is too old, please update to at least 4.2.6.

If it is still there, check that if your firmware updating is really successful. You can try to run linux kernel driver to have a double check.



Regards,

Helin

Subject: [dpdk-dev] i40e_aq_get_firmware_version failure



Hi,



I am trying to start DPDK with 40G Intel NIC and get a failure at initialization stage in i40e_aq_get_firmware_version(). For some reason this function reaches TIMEOUT for more than maximum allowed times (10 times). In the note below I understand that several failures may be considerable but not as many as I have.



Should I enlarge the retries number ?

Is it a HW issue ?



Anyone who faced it or may assist please comment.



Thanks,

Yan

Re: [dpdk-dev] Queries on DPDK working with XL710 intel NIC

[Nissim Nisimov]

Seems like the issue related to the following errors I see in dmesg:

[48459.391753] dmar: DRHD: handling fault status reg 302
[48459.392092] dmar: DMAR:[DMA Read] Request device [21:00.1] fault addr fbaddd000 
[48459.392092] DMAR:[fault reason 06] PTE Read access is not set

I am running on HP ProLiant DL380p Gen8. Ubuntu 3.11.0-26-generic



Is anyone encounter this kind of issue with Intel XL710 NICs (Fortville)?

Thx
Nissim

Re: [dpdk-dev] Queries on DPDK working with XL710 intel NIC

[Roberts, Lee A.]

Nissim,

Recent HP ProLiant servers use RMRRs (see https://www.kernel.org/doc/Documentation/Intel-IOMMU.txt)
to communicate management information.  Use of these RMRRs conflicts with IOMMU usage.

On ProLiant Gen8 servers, you have a couple options:

1) If you are doing bare-metal testing and don't require the IOMMU, turn it off.
   Some kernels have "intel_iommu=on" set by default.  You should be able to use
   "intel_iommu=off" if your kernel enables IOMMU by default.

2) If your application requires the IOMMU, there are BIOS parameters that can be
   configured to eliminate the RMRRs on a slot-by-slot basis.  (I will send instructions
   for this separately, since it is not a DPDK issue.)

                                                  - Lee Roberts

[dpdk-dev] calling rte_eth_rx_queue_setup from secondary processes

[Nissim Nisimov]

Hi all,

I wonder if there is a possibility to call rte_eth_rx_queue_setup() from different processes (for different RSS queues off course)

For example, the code will look something like:


>From Process 1:

retval = rte_eth_rx_queue_setup(port_num, 0, rx_ring_size,
                                                            rte_eth_dev_socket_id(port_num), &rx_conf_default, dpdk_mp_handle);


from process 2:

retval = rte_eth_rx_queue_setup(port_num, 1, rx_ring_size,
                                                            rte_eth_dev_socket_id(port_num), &rx_conf_default, dpdk_mp_handle);




I know that rte_eth_rx_queue_setup() is not meant to work on secondary processes but my question is if there is a real reason for it. and if it can be changed so it will indeed work in such case

Thanks!

[dpdk-dev] Intel fortville not working with multi-segment

[Nissim Nisimov]

Hi,



I am trying to work with Intel Fortville (XL710) NICs in Passthrough mode from a VM running dpdk app.


First I didn't have any TX traffic from the VM, I got dpdk patch for this issue and it fixed it. (http://www.dpdk.org/dev/patchwork/patch/4588/)

But now I see that when trying to run multi-segment traffic not all the packets reaching the VM (I tested it on bare metal as well and saw the same issue)

I don't have support for TSO in my application. Do I need to turn the TSO for the NIC?

Is it a known issue? any workaround for it?

Thanks,
Nissim

Re: [dpdk-dev] Intel fortville not working with multi-segment

[Nissim Nisimov]

Hi,

can someone assist regarding this issue?

Is it a known limitation in i40e/dpdk (no support for multi-segment)?

Thx

Re: [dpdk-dev] Intel fortville not working with multi-segment

[Zhang, Helin]

Hi Nissim

Are you using PF pass-through or VF pass-through?
For PF pass-through, you might have already gotten the fix.
For VF pass-through, there is a bug fix which is needed for supporting jumbo frame and multiple mbuf. http://www.dpdk.org/dev/patchwork/patch/4641/

Re: [dpdk-dev] Intel fortville not working with multi-segment

[Nissim Nisimov]

Hi,

I am using PF pass-through and it doesn't work even with 2000 bytes of server response page size.
Looks like the first segment of each session is not received.

When i am changing the server response size to 1000 bytes, all works as expected.

I am working with dpdk 1.8 version.

Any idea why ? Is it related to i40e multi segment support?

Thx
Nissim

Hi Nissim

It seems that our validation guys here can reproduce it in our lab. I will check that soon later, and update you later.

Hi Helin,

Any news regarding this issue? do u know if there is any related patch I can apply on my application in order to work with multi-segment packets?

Re: [dpdk-dev] Intel fortville not working with multi-segment

[Zhang, Helin]

Hi Nissim

Sorry for late reply!
Today I got a ready environment, and tried the latest DPDK code (on master branch) on my environment, it works well.
So could you help to try the latest code (R2.0 +) on your environment again, to see if the issue is still there or not?

Helin

Hi Nissim

Sorry for late reply!
Today I got a ready environment, and tried the latest DPDK code (on master branch) on my environment, it works well.
So could you help to try the latest code (R2.0 +) on your environment again, to see if the issue is still there or not?

Regards,
Helin
