I have got lenovo carbon X1 Gen8, that works well with 14.0-CURRENT, but
device=0x02f0 subvendor=0x8086 subdevice=0x0070
vendor = 'Intel Corporation'
device = 'Comet Lake PCH-LP CNVi WiFi'
class = network
We have support for iwm9000+ support, but it seems this card has bit
different handling in linux's iwlwifi driver. And just adding new PCI-ID
will not help. Is anyone working on adding support for these cards?

It's an AX201, right? If so, yes. I have no CNVi or AX201 to test
with but assumptions are it will work.

Can I get back to you mid-/end next week?

Hi Bjoern,

is there any news about this driver? I'm ready to test anything that can
allow to disconnect the cable :)

Bjoern, can you share the source code? People can test it, thanks.

+100 from me.

Developers might have seen that I was gone for a while.
I resumed working on this yesterday updating and extracting the iwlwifi
specific bits from my dev repo.

I’ll have a better update for you by Monday evening should life not
interfere again.

It partially did so I am not quite where I wanted to be but here's the promised update:

- I've started an email with core to resolve a licensing policy issue for
importing the driver into HEAD; I was happy about both the feedback I
got and that there was work in progress already on that issue.
This is on-going.

- I've started extracting the driver, firmware, the LinuxKPI and
remaining net80211 changes out of my dev tree into a clean tree that
I can also push somewhere. I've not resolved all LinuxKPI conflicts
yet but hope to finish this all tomorrow.

- LinuxKPI changes are getting extracted into small individual bits
and being reviewed in parallel.

I'll send another update on Thu hopefully with a link to a tree and
some documentation.

Hi

Thanks for the information and also a great job. We are waiting for a link
so we can give it a try.

Sorry, no tree tonight yet.

I have 6 more pci and devres related functions to merge and get through
review and with that the LinuxKPI bits for iwlwifi (modulo wifi which
is self-contained) are in HEAD which simply eases life a lot and will
allow me to focus on the actual work. It'll also make it a lot easier
to get the driver into the hands of people running stable/13 in two
weeks time.

Amongst other things updates comitted this week (thanks to everyone
reviewing!) needed changes for drm-kmod (pull request also submitted
there) and the long-tail story of netdevice (which still is in ofed
and mlx4 which we cannot break) seem to have a possible solution now
(builds finished a few minutes ago).

In addition there's was some other work which need to be addressed and
I hadn't planned for (and more came in an hour ago).

I will continue for another hour or two tonight as I'll not be around
for part of tomorrow.

Next email, with a link.
