FWIW, noticed another such report, this time about the B2502CVA:

This is not a regression, but given how frequently I notice these issues
please as a bystander allow me to ask: is there maybe some way to
improve the situation so that we do not have to add all these and likely
many other Asus Laptops to that file?

Can you next time maybe also add a bit of text explaining why ?

Often the why is trivial, but in this case I wonder what input you want
from me, see below.

Ok, I wonder did you Cc me so that I can write / submit patches upstream
for these ones?

It seems that there are 3 missing models:
- E1404GA: https://bugzilla.kernel.org/show_bug.cgi?id=219224
- X1704VAP https://lore.kernel.org/all/1226760b-4699-4529-bf57-6423938157a3@wanadoo.fr/
- B2502CV: https://bugzilla.kernel.org/show_bug.cgi?id=217760#c12

Which someone needs to submit upstream, right ?

This has been discussed before and unfortunately there is no other way
to deal with this. There has been some discussion about reading back
the polarity and edge/level from the hardware for the keyboard IRQ
to get the values which the BIOS has setup. But it is uncertain if this
will work and no one is working on this.

Not really. Of course it would be nice if you or someone else took care
of that one and...

...these as well -- and ideally would even be willing to act as go-to
person from now on in case more of these quirk entries are needed, which
I guess will be the case. But given the backstory (see below) I don't
think you or anyone else is obliged to do this, even if the current
situation is parlty caused by regressions and recent fixes for them.

A refresher like this was more what I was fishing for. Thx for this.

Now that you wrote it, it makes me think: given the amount of quirk
entries we apparently need I wonder if it might be wise to revisit this
at some point in the not to distant future, as I suspect otherwise
sooner or later Linus might yell at all of us with something along the
lines of "the kernel is clearly broken, why did we work around this with
lots of quirk entries instead of fixing this for real". Something like
that happened in a somewhat (but not exactly) similar situation a year
ago, and it iirc was not the first time.

Writing this lead to another thought: does anyone have contacts to Asus
and could just ask if there is some generic way to detect which of their
Laptops need a quirk?

Ciao, Thorsten

I have already done a bunch of these patches. So I would be happy to
submit more of these, but someone needs to bring them to my attention first.

Also maybe Paul Menzel (added to the Cc) and Tamim Khan can help with
adding more quirks, when reports come in ?

Either way I have submitted a set of patches to add quirks for the 3 new
known broken models now.

I hear you, but I don't really know anyone who has both the expertise
as well as the bandwidth to deal with this.

I don't have any contacts at Asus.

Great, good to know.

That would be great, but nevertheless allow me to ask:

Does anyone now if kernelnewbies has some place where we could submit
requests for creating quirk entries?

I asked in the fediverse, maybe someone knows somebody that can help.
And if not: no harm done.

Have a nice week everyone!
