You can do phone calls (with audio) and you can use mobile data, if you
have the patches for that. :) I'm trying to find time to finish up the
drivers needed for that, but I've been a bit short on time lately.

Actually we have come pretty far with MSM8916-based smartphones.
Most functionality is (somewhat) working at this point, the primary
open task is optimizing suspend/power consumption. Battery/charging
and camera is also tricky but works somewhat on some of the devices.

Most of the functionality is packaged in postmarketOS [1] and you can
find a list of the devices in the postmarketOS wiki [2]. Especially
the ones in the "community" category are quite similar in terms of
working functionality.

Yes, power consumption is a lot of fun :-(.

I know about postmarketOS (I even contributed a bit some time ago),
and watch it from time to time. Currently I'm using old Nokia 6151 for
phone calls, but would not mind switching. Work is ongoing in Droid 4
land -- phone calls are also "almost there". But the almost seems to
be a lot of work :-(.

Best regards,

It's fairly simple on Qualcomm SoCs once audio DSP and modem are working
(which is not that simple). I basically just tell the audio DSP to
stream voice call audio to the audio ports and then it does that without
involving the kernel.

It seems to work quite well, so far no one complained about quality or
something like that. Not sure if anyone is actively using it already
though :)

The work left is mainly making the driver more generic so it can work on
other Qualcomm SoCs as well (right now I have some things hardcoded).
Also, I still haven't fully figured out what is the best way to
integrate it into ASoC/UCM/..., so that it can be easily activated when
starting a voice call.

Ok, thanks for info :-).

On droid 4, we use mixer settings to configure audio system for a
call. Maemo Leste has some kind of component to automatically adjust
mixers when call is started. We use ofonod.
