Hello,

After upgrading the firmware on the bnxt NIC, the NIC is correctly detected by a DPDK application with both DPDK-v20.11 and DPDK-v21.11.

        Regards

        Thierry

Hello Ajit

The card is not correctly probed by the kernel, and so the FW version is
not visible.
Thanks Thierry.
I thought it was just the PMD running into trouble.

Can you give details of the ARM server?
Make, Vendor, etc..?

This a Huawei server:
TaiShan 200 Server (Model 2180) aarch64, 48 cores, 2.6GHz, 64GB RAM

Ok. I tried this on a HUAWEI Kunpeng 920 running 4.18.0-
348.2.1.el8_5.aarch64.
I can load the bnxt_en kernel driver and the DPDK PMD without issues.
And I did load vfio with enable_unsafe_noiommu_mode=1 .

While we are pursuing this further internally,
I have added Honnappa to see if he can provide any insight.
There is not much information on the error.
Just wondering if it is possible to move the card to x86 machine and check the 
firmware version and upgrade the firmware version there.

I see this in the kernel dmesg:
bnxt_en 0000:03:00.0 (unnamed net_device) (uninitialized): Error
(timeout: 500015) msg {0x0 0x0} len:0
bnxt_en 0000:03:00.0 (unnamed net_device) (uninitialized): Firmware not
responding, status: 0x8ffff

And then there are no bnxt_en netdevices.

          Best regards

          Thierry

Hello Ajit

Thanks for the quick response.

Please keep me posted when you check on your side.
Can you tell what is the firmware version on the card?


           Best regards

Is this a know issue ?
No.
We have tried the Broadcom PMD on ARM server(s) and have been
able to use it without any issues.
But we can try it again and get back to you.



            Thanks

PS: a similar error is seen for the Ethernet ports, when handled by the
kernel:
dmesg|grep bnxt
