Re: [PATCH 00/10] Fix documentation warnings at linux-next

[Lukas Bulwahn]

[reduced the recipient list to the main responsible ones and list]

Hi Mauro, hi Jonathan,

We both, Mauro and I, have been submitting patches to address the
documentation warnings on linux-next. If it is okay with you, Mauro, I
would like to take responsibility for the task to send out the patches
to address all warnings on linux-next in make htmldocs and follow up
with all the discussions. I can also provide a short weekly summary
(probably always on Friday) on what is pending where and what I could
not resolve by myself.

Is that okay for you?

If at some point I do not have the time to take care anymore, I will
let you know.


Best regards,

Lukas

Yeah, sure!

Anyway, after applying the patches I sent this week, the warnings
I'm getting are all due to the validation scripts I wrote. So, if 
everything gets merged (either yours or my version), we'll have zero
Sphinx/kernel-doc warnings again.

The script-validation warnings are:

1. Broken cross references

It sounds that part of the above is due to DT patches that weren't
merged yet, but there are a few others that can be solved, but may
require discussions with some Kernel developers/maintainers.

Perhaps you could check with Jonathan Cameron some strategy to address
the IIO warnings.

It is a never ending story... I already have seen two new warnings on
today's linux-next and sent out patches.

I will also try out those two scripts, but I cannot commit to
follow-up on all of those yet. I am also looking into addressing all
kerneldoc warnings, even if not pulled in by make htmldocs.

Yes, I know. After 5.10, it is easier to track new stuff, as
Sphinx/kernel-doc warnings were all shut up there.

Yeah, some of those are not trivial to address.

FYI, those are called by default after make allmodconfig/allyesconfig.

Make sense. There are lots of kerneldoc warnings for files that 
aren't currently part of the docs building system. It makes sense to
fix those and add them to the Sphinx build logic.

Here, I have a local script that checks for those:

	for i in $(git grep -h "\.\.\s*kernel-doc::" Documentation/|cut -d':' -f 3|grep -vE "\bsource$"|sort|uniq); do
		./scripts/kernel-doc --none $i
	done

It reports 101 warnings against next-20210114.

Thanks,
Mauro

In time: those are for the ones that are included, but that
doesn't have all symbols added. I have another one somewhere
that does a more deeply check. I submitted it as a RFC sometime
ago to the docs ML:

	https://git.linuxtv.org/mchehab/experimental.git/tree/scripts/docs_check_exports?h=doc_export_symbol&id=3f7d1e1b0bcdbe1d95eaa4b256259dfaa08faece

Such script checks only exported symbols.

Mauro

I'm being a bit rubbish on those ones. All need a bit of thought...

I'll try to kill off a few of them this weekend as *touch wood* my
review queue is looking fairly short.

I'm certainly not going to complain about warning fixes!  If you want to
take up this work, all I can say is - I'm looking forward to the patches.
Thanks for doing this.

As I mentioned in the cover letter for the series I've just sent out, I ran into
a bit of an understanding gap around the two counter cases.  This isn't helped
by the fact it is at least partly deprecated ABI given the counter subsystem
has much richer ABI for these types of devices.

@Fabrice, Benjamin and William.
What do we do about that one?

I'd consider the IIO counter ABI as entirely deprecated -- the Counter
subsystem supports all the functionality that's provided by the IIO
counter ABI, as well as additional functionality that is missing. 

Regarding the iio:deviceX/in_count_quadrature_mode_available attribute:
superseded by the Counter subsystem counterX/countY/function attribute.
The IIO counter ABI allows users to select between a quadrature counting
mode or a non-quadrature counting mode; unfortunately, it does not
specify what kind of quadrature or what kind of non-quadrature counting
is actually being performed by the device.

Because the 104-quad-8 and stm32-lptimer-cnt drivers were the only ones
to use this attribute, they are luckily in sync -- both define the same
possible modes available: "quadrature" and "non-quadrature". You could
simply consolidate this attribute to the main sys-bus-iio file in order
to resolve this warning.

Given that it has already been superceded by the Counter subsystem, I'd
also be all right with just removing the IIO Counter ABI entirely from
the codebase, or alternatively setting a future date for removal.

I agree that we should look to remove this ABI.  If we can establish no one
is relying on it today then we can drop quickly.  If not it would be good
to establish when we drop it.

Fabrice, Benjami any thoughts on the stm32-lptimer-cnt?

I'm going to hazard a guess that there aren't many 104-quad-8 users
that you don't know about William, so if you think we can immediately drop
the interface from that, lets do so, whether or not we can clean up
the stm32 one at the same time.

Hi Jonathan, William,

I apologize for the late reply, being busy on other topics. I think the
stm32 timer driver need some cleanup to remove this ABI:

- stm32-lptimer-counter indeed is similar to 104-quad-8 driver. It still
registers an IIO device with the "preset" attribute pointed out in the
doc warning. Yes, the counter interface covers the same.
So, I agree this ABI could be removed here. Still, I don't know if there
are users for the IIO counter ABI.
Dummy question... Is it needed to drop driver part and ABI, at the same
time ?

- stm32-timer-trigger driver which resides in iio, also registers preset
attr being pointed out above. I'm more concerned there: I think some
modes may depend on the preset attr, even for the trigger. Partial
removal was done by Benjamin earlier (after stm32-timer-cnt addition).
still I need to double check this.

At least dropping the stm32-lptimer-counter part, should avoid the
Warning here. So it may probably be ok in the short term?

Please advise,
Best Regards,
Fabrice

[PATCH 00/10] Fix documentation warnings at linux-next

[Mauro Carvalho Chehab]

This series fixes the documentation warnings found at next-20210114.

Most of the changes here are trivial. 

While those patches could be merged via the docs tree during
the next merge window, It sounds better to have those patches 
merged directly via each maintainer's tree, where the new
warnings were introduced.

Regards,
Mauro
