Hi folks,
I'm not really sure whether this is related to the manual page
itself or the driver, so bear with me please.
Reading the manual page, it's not immediately clear what devices
are supported without going not just to the source but seemingly
outside of the tree completely - so maybe it'd be a good idea to
list the devices; going by src/sys/modules/iwlwifi/ it's a pretty
good collection and I'm sure a lot of people would like an easy way
to know whether theirs are supported or not.
I'll add that to the man page. It's a bit of a silly thing we once
started a long time ago and definitively is needed for other chipset
which are massively reselled by a gazillion vendors.
I'll try and see if I can automatically generate that list as
otherwise every new driver update lately almost added new IDs.
Another thing I noted is that there's it's a bit ambiguous whether
iwlwifi(4) is supposed to replace iwm(4) and perhaps others - but
from the blobs in the before-mentioned folder, I'm assuming that
that is the intention. If it is, then there should probably be some
sort of documentation on how this is to be achieved; I'd assume
it's done via hints, but having to figure out how from first
principles isn't the easiest (I know I'd struggle, although I might
eventually succeed).
If you want to try iwlwifi on a currently supported iwm(4) device,
there is info on the wiki page which I am still editing *sigh*.
The idea is to probably long-term not have both drivers but before we
can get there, iwlwifi needs to improve and have parity on a few
things with iwm(4).
If the only impediment is ENOTIME, I'd be happy to work on making
the mdoc changes, provided I can have a enlightenment in how to
figure out:
1) Exactly which devices are supported
2) The steps to ensuring that iwlwifi(4) gets used over iwm(4) and
others.
My current suggestion is: if you have a working iwm(4) only try
iwlwifi(4) at this time if you have an actual need or do want to try.
This recommendation might change in a month or 4.
There's a lot of people with newer chipsets than iwm(4) supports who
do not have that option currently.
I hope the updated wiki page will clarify some of this.
Happy New Year 2022!
