Intel AX210 doesn't work on PCIe without msi-x support

Hi I have tried to get Intel AX210 up and running on a Xilinx ZCU102 board without any success.

 

I have attached some logs from lspci -vvv and iwlwifi logs both with iwlwifi-ty-a0-gf-a0.pnvm in /lib/firmware and not. This is a suggested solution by many people who has issues to bring up the Intel AX210 on the internet to remove the iwlwifi-ty-a0-gf-a0.pnvm file from /lib/firmware but it doesn't help.

 

I'm pretty sure the problem is related to missing msi-x support in the root pcie on the PS side of the ZCU102 UltraScale+ .

 

See the line of the log iwl_pcie_set_interrupt_capa Failed to enable msi-x mode (ret -524). Moving to msi mode.

 

Question is msi-x support necessary to get AX210 up and running ? Could it be a issue in the ucode firmware uploaded to the the module ?

 

We are running on Linux 6.1.40-xilinx-v2023.1 from Langdale

 

Finally we can easily bring up the same Intel AX210 board on a simple imx6 soloX processor that has msi-x support running Linux 6.1.1 #1 PREEMPT. So we also know that the Intel module is working.

 

On the ZCU102 UltraScale+ we can also bring up the Intel 7265 and Intel AX200 but not the AX210

 

Best regards

Hello @Esben,


We sincerely appreciate your patience.


After conducting thorough research, it has come to our attention that the AX210 wireless module operates on a distinct platform. We recommend reaching out to the system manufacturer, MSI, to validate whether your motherboard is compatible with the AX210 wireless module and to explore the possibility of acquiring MSI-X support from them.


Given that this matter pertains to the motherboard manufacturer, we will proceed to conclude this discussion thread. If you require any additional information or assistance, kindly submit a new inquiry, as this thread will no longer be actively monitored.


Warm regards,

Isaac Q.

Hi
Just to clarify it has nothing to do with MSI as the motherboard manufacturer. MSI is referring to Message Signalled Interrupts (MSI). I still believe there is something wrong in the Intel module. In the mean time I have succeeded to bring up a qualcomm wcn6856 WiFi 6e module. This module supported only MSI (message signal interrupt) and did not need the platform to support MSI-x a vector based signal message interrupt signaling. Please read my first post again with the knowledge that MSI is meaning message signal interrupting.
Best regards
