[linux-nfc] [PATCH 1/2] MAINTAINERS: nfc: add Krzysztof Kozlowski as maintainer

[Krzysztof Kozlowski]

[-- Attachment #1: Type: text/plain, Size: 1160 bytes --]

The NFC subsystem is orphaned.  I am happy to spend some cycles to
review the patches, send pull requests and in general keep the NFC
subsystem running.

Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@canonical.com>

I admit I don't have big experience in NFC part but this will be nice
opportunity to learn something new.  I am already maintainer of few
other parts: memory controller drivers, Samsung ARM/ARM64 SoC and some
drviers.  I have a kernel.org account and my GPG key is:
https://git.kernel.org/pub/scm/docs/kernel/pgpkeys.git/tree/keys/1B93437D3B41629B.asc

Best regards,
Krzysztof

NFC has been lost in the limbos since a while. Good to see someone
volunteering to take care of it.

May I suggest to create a simple nfc reading program in the 'tools'
directory (could be a training exercise ;)

Noted, thanks. I also need to get a simple hardware dongle for this....

Krzysztof, the NFC portion of the kernel has a counterpart in userspace
called neard.  I'm supposed to be maintaining it but I have next to no
time to do so.  If you have spare cycles, any help would be appreciated.

Anyway, in neard, there are some simple test scripts (python2 - I/we need
to update to python3).  The current home of neard is:

git://git.kernel.org/pub/scm/network/nfc/neard.git

I guess none of us have problem of too much spare time :), so it took me
a while before I looked at neard.

With newer Gcc, neard did not even compile (which I am fixing now). I
set up a fork:
https://github.com/krzk/neard
However I can give early disclaimer - playing with GLib userspace code
is not something I am in long term interested. If this was written in
Rust, would be different story. :)

I also configured basic CI (or rather continuous building):
https://github.com/krzk/neard/actions/runs/1014641944

However I still do not have proper testing setup. No hardware. Would be
nice if Samsung. ST, NXP or Intel could spare some development board
with the NFC chip supported by kernel. Till then, I will try the NFC
simulator and virtual NCI drivers.

My next plan for neard is to extend the CI. There is no way I (or anyone
else I believe) can keep good quality of releases without automated
checks. I'll add some more distros, clang and later many some linters or
cppcheck.


Best regards,
Krzysztof

Hi Krzysztof, I see you've been busy.  Thanks for that.

FYI, I made a repo on github some time back but never announced it.  The
only reason I mention it is because the name/link looks more official:

	https://github.com/linux-nfc/neard

Let see what happens with permssion on kernel.org and go from there.

Re: hardware - I don't have much reader hardware either.  I almost
exclusively use BeagleBone[Black] + RF Cape + trf7970atb.  I also have
a USB dongle with a pn533, FWIW. I do have a decent collection of NFC tags,
though.  I'll contact you privately to arrange to send some to you.

For peer-to-peer testing, your smartphone probably has an NFC reader but
you'll have to play around to find the sweet spot where they put the
antenna (older phones were notoriously bad for NFC antenna design; newer
ones are generally better).

I will review your patch sets but the earliest I will get to them will
be Sunday.

Mark

For the kernel.org I think you need an account @kernel.org (which itself
requires your key to be signed by someone), but I am not sure.

I am happy to move entire development to github and keep kernel.org only
for releases till some distro packages notice the change. If Github,
then your linux-nfc looks indeed nicer.

Thanks! I managed to do some testing with nfc-sim modules, although I am
not sure how much is supported.

Yeah, I just ran into this yesterday.  You need a key signed by at least
two people who already have k.o accounts.  With that, and your name
in the MAINTAINERS file, you can get an acct pretty quickly.  I need to
set that up and get some signatures.  That will take a while for me.

Okay, lets do that.  I'm the owner so I can give permissions to whoever
needs them (e.g., you :).

Then please assign some to the account "krzk" on Github. Thanks!
