First of all thank you Bjoern and anyone that has contributed to iwlwifi and all the work that you have done. I've been following this list semi-closely since November, but I haven't had the possibility to test rtw88 until now. Yesterday I updated my system to latest STABLE, having read that iwlwifi had already been MFC'd to upstream. But I have no clue where did rtw88 go, as only if_iwlwifi.ko is appearing in /boot/kernel. Has rtw88 support been dropped, am I missing the kernel file, or should I do any other procedure to build it? I am willing to test.
It's missing one or two linuxkpi changes which will come with the next batch to build out of main (not stable/13). To my surprise it did attach without error on my amd64 machines now (where previously firmware loading was a hit-and-miss). On arm64 there's still issues. I assume some of them are there on x86 but "hidden" by other things. I can create wireless interfaces as well and trigger scanning but I am currently not receiving frames (which is a common thing between rtw88 and rtw89) and I simply had no time to look into this yet. Likely a LinuxKPI compat bit is missing. I'll try to find a few hours once changes for iwlwifi are out. After basic packet passing works as it does for iwlwifi I'll make sure to get it into the tree altogether. If you want to try earlier I can provide an updated tarball again (including firmware) and the 6-line diff to attach them to the build once the LinuxKPI bits are in. I'll be very keen to hear from testing on non-developers systems. /bz PS: as we have just discovered there is a secondary issue with rtw88 in that it'll overflow an mbuf size when used with IPv6 in a few places [1]. I am currently testing a temporary work-around for that which should hold the next few weeks.
