iwlwifi fails to load with model ax200-series #5615

raedah · 2020-02-01T06:42:17Z

Qubes OS version
4.0.3 Fresh install, Fedora 30 Template

Affected component(s) or functionality
iwlwifi for AX200 based cards

Brief summary
AX200 is only supported on kernel 5.1+, so kernel-latest-qubes-vm is needed for sys-net. At that point numerous errors repeat in the dmesg.

Appears this may be a problem in Fedora directly.
https://bugzilla.redhat.com/show_bug.cgi?id=1790231

zeroqn · 2020-02-01T11:59:48Z

AX200 doesn't work in debian template.

ejose19 · 2020-02-02T14:07:41Z

Can confirm this is an issue, doesn't work with any template (debian, fedora, archlinux) however if running any of those distros directly the wifi is working properly.

raedah · 2020-02-02T17:48:26Z

Can anyone confirm a vm kernel version that works without these crashes?

fmeef · 2020-02-03T01:28:13Z

Can confirm I have this problem too with an intel wireless-ac 9462 on a thinkpad x1 carbon 7th gen with an intel 10th generation i7. The issue is present both on 4.0.3 stable and 4.1 (built from master branch using qubes-builder).

/var/log/xen/console/hypervisor.log complains about [VT-D]DMAR" reason 06 - PTE Read access is not set when attempting to assign the device

fmeef · 2020-02-03T04:32:55Z

Interestingly, dom0 seems to have the iwlwifi kernel module loaded. Could this mean the wireless card was attached to dom0 before the netvm had a chance to grab it? If this is a problem, is there a way to prevent this from happening?
edit: I tried blacklisting the driver and adding the pci device to the rd.qubes.hide_pci kernel option and the original problem still persists

v6ak · 2020-03-19T22:24:44Z

I have an issue with similar symptoms: https://groups.google.com/forum/#!topic/qubes-users/7VcN8kkKop0

Noteworthy parts:

Bare-metal Fedora 31 Live works, the same image in a HVM with attached Wi-Fi card does not work.
I see some suspicious lines in stubdom log. Maybe it is a stubdom incompatibility.
I don't have iwlwifi loaded in dom0, though.
You need kernel 5.2+ or 5.1+ (sources vary on minimum version). So, you probably need to use HVM for sys-net and configure no kernel in order to use the kernel from VM template.

marmarek · 2020-03-19T23:12:45Z

@pwmarcz is the same as with your new laptop?

pwmarcz · 2020-03-19T23:52:51Z

My card is Intel Wireless-AC 9462. This happens after trying enable the interface (ip link set wls7f0 up):

That's on kernel 5.4.24, but I get the same on 5.5.9.

This is a System76 laptop, and the manufacturer's own PopOS (with stock Ubuntu kernel 5.3.0-7625) loads wifi when booted directly, but fails in a similar manner when run under Qubes as an HVM doman.

Experiencing this as well using an AX200 (rev 1a).

QubesOS: 4.0.3 fresh install
dom0 kernel: 4.19.94-1.pvops.qubes.x86_64
sys-net kernel: 5.5.7-1.qubes.x86_64

I've tried this under a Fedora 30 VM and a Debian 10 VM. With microcodes iwlwifi-cc-a0-46 and iwlwifi-cc-a0-48, both giving the same error.

Also tested a a combination of dom0 with kernel-latest and sys-net on kernel and kernel-latest both with Fedora 30 and Debian 10 with no success.

I previously had NixOS (unstable) installed on this laptop baremetal with wifi working fine on a 5.1+ kernel, which leads me to believe this might have something to do with the firmware and xen.

Following the suggestions from https://groups.google.com/forum/#!topic/qubes-users/7VcN8kkKop0:

1. Some config space access is filtered and driver doesn't cope with it.

For the first hypothesis, I'd try enabling permissive option (AFAIR
didn't helped in itself), but then enable verbose logging in pciback
driver:
echo 1 > /sys/module/xen_pciback/parameters/verbose_request
before starting sys-net.

I forgot to set the device to permissive. This device is set for no strict reset though. After enabling verbosity, I ran dmesg -w | tee -a out in dom0, then modprobe -a iwlwifi in sys-net. Output:

Ran rmmod iwlmvm && rmmod iwlwifi which outputted the last line.

2. Some extended PCIe feature that driver/firmware assumes present is not implemented in PCI passthrough.

For the second hypothesis, I'd take lspci -vv of the device from both
sys-net and dom0 (preferably in exact the same time, during enabling the
interface, but that's unrealistic). And compare.

In dom0:

Thanks for the logs @boundless-thread !

@pwmarcz recently did some debugging here and identified a workaround. Mail to linux-wireless mailing list is here: https://lore.kernel.org/linux-wireless/[email protected]/T/#u

v6ak · 2020-04-14T19:31:59Z

Thank you, it works for me. I have succeeded with compiling Fedora kernel with that patch. Probably just iwlmvm.ko is needed to be replaced, but I am not sure if it is easy to build just that. Note that Fedora kernel compilation takes fair amount of space. I have seen up to about 36GiB space used, so I recommend giving the VM at least 40 GiB private volume.

process0 · 2020-04-20T16:40:14Z

@marmarek & @pwmarcz : Have you tried testing it against https://lore.kernel.org/linux-wireless/[email protected]/ to see if it resolves this issue?

It might be useful to CC them.

Edit: I've tried the latest mainline (5.7.0 rc2) on fedora 30 and still get the same errors, so the link above hasn't fixed anything.

I confirm this work around makes the AX200 WiFi operational on a Lenovo P53 with kernel 5.6.13-1. Bluetooth is not working as not initialized AFAIU.

The code bypassed seems to be used to initialize each (but the default?) queues:
{q_num, DMA address of free BD cyclic buffer, DMA address of urbd_stts_wrptr, DMA address of used BD cyclic buffer, Initial write index of the free BD cyclic buffer} if it helps someone who investigates on the Xen side.

prdn · 2020-08-25T10:21:36Z

I'm having the same issue.
Did any new kernel solve the issue?
Otherwise would it be ok to create a branch (ie. stable-5.4-ax200) in the qubes-linux-kernel project that patches the kernel automatically?

See QubesOS/qubes-issues#5615. To enable, add `iwlwifi.disable_rxq=1` to kernel options: opt=$(qvm-prefs --get sys-net kernelopts) qvm-prefs --set sys-net kernelopts "$opt iwlwifi.disable_rxq=1"

pwmarcz · 2020-10-01T10:08:33Z

There is a workaround in the newest Qubes kernel (see QubesOS/qubes-linux-kernel#275) that basically enables the bypass mentioned above. To enable:

install kernel-latest-qubes-vm version 5.8.11-3 in dom0 (available via the current-testing repository)
shut down sys-net
go to qube settings for sys-net, use 5.8.11-3 kernel
add iwlwifi.disable_rxq=1 to kernel options for sys-net:

opt=$(qvm-prefs --get sys-net kernelopts)
qvm-prefs --set sys-net kernelopts "$opt iwlwifi.disable_rxq=1"

start sys-net again

ejose19 · 2020-10-01T11:49:40Z

@pwmarcz Thanks for making such a simple and practical solution, as WiFi 6 is becoming more common in newer mobos I'm sure new users will appreciate it as well. Confirmed it works following those steps.

aslfv · 2022-09-03T04:33:43Z

I am happy to confirm that my wifi (AX211) is now working after performing the patch as described by @scsich. I am happy not only because I can get rid of my usb adaptors, but also because of the joyful/interesting experience and gained ability to patch my system :) @marmarek I still look forward to the new kernel. Many thanks to all again, including @jandryuk !

1. Some config space access is filtered and driver doesn't cope with it.

2. Some extended PCIe feature that driver/firmware assumes present is not implemented in PCI passthrough.
