Description Blake 2020-04-03 00:50:56 UTC
The current IWM driver won't support Intel Corporation Wireless-AC 9262.
Comment 1 Blake 2020-04-03 00:51:53 UTC
This is the default wireless card of the NUC10i7 and probably other NUC10's as well.
Comment 2 Mark Johnston freebsd_committer 2020-04-03 13:30:22 UTC
Can you show the pciconf -lv entry for this device?

The device is *physically* labelled (on the m2 card in my laptop) as 9560. Adding the 0x02f0 device ID to the `iwm` driver -- and a config struct,

```
?       sys/contrib/dev/iwm/iwm-9462-48.fw.uu
M       sys/dev/iwm/if_iwm.c
?       sys/dev/iwm/if_iwm_9462.c
M       sys/dev/iwm/if_iwm_config.h
M       sys/modules/iwm/Makefile
M       sys/modules/iwmfw/Makefile
?       sys/modules/iwmfw/iwm9462fw
```

got me quickly to iwm trying to load some firmware and failing: `unknown firmware section 55`. The firmware I was trying to load was iwlwifi-QuZ-a0-jf-b0-48.ucode -- based on that **that** file exists in my Linux installation on the laptop, and the errors in dmesg.
Comment 5 Adriaan de Groot freebsd_committer 2020-04-11 21:18:48 UTC
- Shouldn't the bug title be 9462, rather than 9262?
- I went looking at the Intel firmware page, and the one listed for 9462 (for Linux kernels 4.14+ uuencodes to something different from what's in the FreeBSD -current tree)
Comment 6 Blake 2020-04-12 02:08:00 UTC
(In reply to Adriaan de Groot from comment #5)
You are correct.  Sorry about that.
