Sensors support

Based on the work done by the pmOS folks at pmaports!4050. As of today, I haven't been able to get sensors to work, then this is my log collection to find out what I'm doing wrong...

As far as I'm able to understand, situation in *bian is:

  • kernel should already be fine, being based on sdm845-mainline repository as pmOS
  • FW files are handled by droid-juicer
  • sensor files are missing in Debian, probably droid-juicer can take care of those as well?
  • libqmi, the version in Debian includes the relevant changes
  • libssc (now in Debian, experimental branch)
  • hexagonrpc, it's not in Debian
  • iio-sensor-proxy, the relevant branch is not yet merged, then it's not released nor officially available

Summarizing the missing points in *bian:

  • sensor files
  • hexagonrpc
  • iio-sensor-proxy

Udev rules and systemd services are inspired by hexagonrpcd packaged in Alpine. After installing this, I've also made sure to add mobian user to the fastrpc group (sudo adduser mobian fastrpc).

iio-sensor-proxy (3.5-1) unstable; urgency=medium

  * New upstream release
    - Install D-Bus policy to /usr instead of /etc/ (Closes: #1041775)

Results

In my understanding, each component can be placed at a different level from the bare metal to user-facing:

  • kernel/FW/sensor files
  • libssc/hexagonrpc
  • iio-sensor-proxy
  • Phosh/Plasma

Let's check at step 2 (libssc), if the underlying components are doing their part.

mobian@mobian:~$

Seems like we already have issues at this level: Service SSC not found (but libssc package in Alpine does not have any service) and unknown sensors.

Another check, hexagonrpc

mobian@mobian:~$ hexagonrpcd 
Usage: hexagonrpcd [options] -f DEVICE

Server for FastRPC remote procedure calls from Qualcomm DSPs

Options:
        -d DSP          DSP name (default: )
        -f DEVICE       FastRPC device node to attach to
        -p PROGRAM      Run client program with shared file descriptor
        -R DIR          Root directory of served files (default: /usr/share/qcom/)
        -s              Attach to sensorspd
mobian@mobian:~$ ls /dev/ | grep fastrp
fastrpc-adsp
fastrpc-cdsp
fastrpc-cdsp-secure
mobian@mobian:~$ sudo hexagonrpcd -f /dev/fastrpc-adsp

the last one does not return, even leaving there for hours.

Last test, iio-sensor-proxy: its README recommends to check sensors being recognized by looking at udevadm info --export-db.

mobian@mobian:~$ udevadm info --export-db | grep iio -A6 -B1

it seems like a couple of devices are recognized. OTOH, the first one seems like a voltage measurement on some power rails, while the second something similar related to the battery.

I will have to check what's the output of udevadm info --export-db under pmOS, but it seems like something is not working at step 1 (kernel/FW/sensor files)...
