[SRU][F/raspi][G/raspi][H/raspi][PATCH 0/1] No iwilwifi driver in Linux 5.4.0-1034-raspi (LP: #1925209)

[Juerg Haefliger]

[Impact]

The Raspberry Pi CM4 exposes a PCIe bus and the AX200 Wifi plugin card should therefore be supported.

[Test Plan]

$ modinfo iwlwifi
modinfo: ERROR: Module iwlwifi not found.

[Where Problems Could Occur]

It's a new module which might need firmware. If that blob is not available, users might ee dmesg errors. And obviously if the module is buggy all hell could break loose.

[Original description]

Hello,

I have installed Ubuntu Core 20 edge built on 19.04.2021(https://cdimage.ubuntu.com/ubuntu-core/20/edge/) in Raspberry Pi CM4.

Operating System: Ubuntu Core 20
Kernel: Linux 5.4.0-1034-raspi
Architecture: arm64

I have inserted a Intel AX200 Wifi Adapter in PCIe slot in Raspberry Pi CM4. The device is recognised

$pciutils-snap.lspci
00:00.0 PCI bridge: Broadcom Inc. and subsidiaries Device 2711 (rev 20)
01:00.0 Network controller: Intel Corporation Wi-Fi 6 AX200 (rev 1a)

But the iwlwifi driver is not available.

$lsmod | grep iwl
$

iwlwifi is the driver needed for intel wireless chips(https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi).

Is there a possibility to enable the iwlwifi driver?

Thanks
Hema
