N900 kernel support

N900 kernel support

[Pali Rohár]

Hi! Yesterday I updated https://elinux.org/N900 page based on data which
I found in linux git repository. So driver status should be up-to-date.

I would like to ask, what is current status of the bluetooth driver? It
is working on N900, or it has a problems?

Also are the any plans for bringing front webcam to work? IIRC there was
problem that it was not possible to describe in DT that back and front
cameras.

And what happened with ramp mode for camera autofocus?

It's not currently in mainline. That mode is more or less useless for any
decent AF algorithm as it does not implement functionality typically needed
from lens drivers.

I guess you could implement support for it by using custom controls but I
don't think it's really good for anything.

I have not tested this personally, but the driver for it is upstream.

Sebastian knows more. Driver is upstream and working for
N950. Unfortunately it does not really work on N900.

See other email.

Front webcam... Few lines of code (or maybe only few lines of dts) and
perhaps quite a lot of debugging would be required there. OTOH... its
quality is not great, so...

BTW main camera only works in 1.3MPix mode. Getting 5MPix there would
be nice...

We don't have userland application using those, so it was easier not
to merge them. It is few lines of code if you have application needing
these.

Best regards,

BTW... do you have any reasonable userland to run on n900?

I'm currently playing with postmarketos --
https://wiki.postmarketos.org/wiki/Nokia_N900_(nokia-rx51)  -- lots of
fun, but still a lot of work to do....

There is devuan jessie N900 image, I guess it is reasonable enough. Just 
google for it.

Maemo 5 with some modifications worked with some 4.x kernels (probably
4.6 or 4.7). I have not tested recent versions.

And Maemo 5 is usable userland, just still closed...
