rtwifi.ko: Unknown symbol in module

ZerBea commented 3 years ago

Compiles fine on $ uname -r 5.10.9-arch1-1 except 2 warnings: rtl8xxxu_desc_to_mcsrate defined but not used rtl8xxxu_legacy_ratetable defined but not used

but its not possible to insmod the module $ sudo insmod rtwifi.ko insmod: ERROR: could not insert module rtwifi.ko: Unknown symbol in module

did you try sudo depmod -a after copy rtwiki.ko to

/lib/modules/<<kernel e.g. 5.10.9-arch1-1>>/kernel/drivers/net/wireless/rtwifi.ko

ZerBea commented 3 years ago

I don't run the module from inside the modules directory. Maybe I should run "modprobe mac80211" before insmod. I'll try that. Thanks for pointing me into that direction.

ZerBea commented 3 years ago

That did the trick. rtwifi.ko doesn't load mac80211. It must be done by hand. Thanks.

@kimocoder no longer NETLINK dependencies.

I know, the driver is highly experimental, but I decided to add it "known as working" to hcxdumptool: https://github.com/ZerBea/hcxdumptool/commit/03c3b957e33053b5baa7ca1a6fa0a8e5534acbb3 because it is working much better than the old ones!
