iwlwifi: intel ax210: module fail load firmware: Failed to start RT ucode: -110

[Florian Schmidt]

Hello, I've been trying to use an intel ax210 minipcie board on an arm32 platform. I could use an intel ax200 on the same platform without issues but with the ax210 it always fail.

How can I assist in debugging this issue ?

Below are some system information and the output of dmesg when loading iwlwifi:

The problem here (at least what I can understand from the log) is that the PNVM binary is missing.
Indeed, it's not required for ax200 device, but it's needed for ax210 device.
You can take iwlwifi-ty-a0-gf-a0.pnvm from 
http://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git and place it along with
the frimware file in /lib/firmware.

Re: iwlwifi: intel ax210: module fail load firmware: Failed to start RT ucode: -110

[Florian Schmidt]

Hi Gregory,

Thank you for having a look at this. The .pnvm file was present in my test as shown by my original message:
> md5sum /lib/firmware/*
> 787381c60d907f81a3ddadc5c990a82b ./iwlwifi-ty-a0-gf-a0-71.ucode
> d93cbdcc4bb5be69aac128e2fe291359 ./iwlwifi-ty-a0-gf-a0.pnvm
> 33d13d236512466e71c81257209a356f ./regulatory.db

I just ran the test again, ensuring I have the .pnvm you mention and the result is indeed the same.

Any other ideas to solve this are welcome.

Thanks,
Florian

The driver indicated it wanted to load iwlwifi-ty-a0-gf-a0-72.ucode, 
which you do seem to have based upon the listing above?

Hi Florian,

Indeed, my first log seems to load -72.ucode when my dump show a -71 file, that's strange. I must have mismatched some test, sorry for the confusion. During my tests, I've actually tried with many different firmwares (I think I've done all the compatible firmware I could find), tested both with and without the pnvm file and many kernel versions, it always seems to fail. The suspicious thing to me is that during my tests, I've confirmed several times that the same sets of wifi card, kernel and firmware work well on my intel desktop.

Below are the logs from my latest test today with firmware -71 and the .pnvm from git.

I'd be happy to help debug more, but I have zero visibility on the firmware so those register dumps just mean nothing to me. Let me know how I can assist with this.

Florian

During my tests, I've actually tried with many different firmwares (I think I've done all the compatible firmware I could find), tested both with and without the pnvm file and many kernel versions, it always seems to fail. The suspicious thing to me is that during my tests, I've confirmed several times that the same sets of wifi card, kernel and firmware work well on my intel desktop.

I am not familiar with ax210, but have worked quite a bit with the 7260 
chips (iwlwifi) and errors like those typically occurred when the PCIe 
end-point device, that is the ax210 is not able to do PCIe inbound 
accesses into your system's memory. Now in your case it could be that 
the inaility to load the appropriate ucode results in ... you guessed 
it, the ucode not being loaded which causes the timeout to happen.

Can you tell us more about your ARM32 system here? What PCIe host 
bridge/controller does it use, do you have an IOMMU attached to that 
PCIe host brideg somehow?

Thanks!

During my tests, I've actually tried with many different firmwares (I think I've done all the compatible firmware I could find), tested both with and without the pnvm file and many kernel versions, it always seems to fail. The suspicious thing to me is that during my tests, I've confirmed several times that the same sets of wifi card, kernel and firmware work well on my intel desktop.

We're using a Xilinx FPGA Based PCIe root complex on a custom zynq-700 board. The doc of the PCIe block can be found here: https://www.xilinx.com/content/dam/xilinx/support/documents/ip_documentation/axi_pcie/v2_8/pg055-axi-bridge-pcie.pdf

I'm not really familiar with IOMMU (or PCIexpress) but to my knowledge there is no support of IOMMU on our arm32 platform, at least I couldn't enable it in kernel options, it required some other platform flags.

You can find everything lspci has to say about our device below.

I tried exactly this combination of firmware and PNVM versions on a couple of (Intel based) machines
that I have and the driver loads ok. It can point to some PCIe related issue indeed. I see we already
have a related bug, that probably covers a bunch of different issues with similar behavior. Maybe you can
try the suggestion from the last comment https://bugzilla.kernel.org/show_bug.cgi?id=212371#c34?
If you will be able to enable IOMMU, it'd be possible to get a firmware debug dump that can shed some
light on what's going on there.

Hi Gregory,

Regarding the bugzilla comment, I can't remove "pci=nomsi,noaer" from bootargs. They're were never there (my bootarg are "console=ttyPS0,921600 earlyprintk uio_pdrv_genirq.of_id=generic-uio"). 
Kernel config PCIAER is enabled. The listing above from lspci -v seems to indicate that MSI is working properly, it enabled one vector for the ax210. This all indicate I should be in the suggested configuration.

Unfortunately, this hardware (Xilinx Zynq-7000) has no IOMMU support.

I've also tried the same kernel/firmware/pnvm on x64 and x32 intel computers without issue.

On which level of PCIe do you think the issue would be? I could get access access to a serialtek pcie analyzer if this kind of low level trace could be of any help investigating the issue.

Thank you for taking time to help with this,
Florian
