# pdx213-temp

Some notes on my work getting Mobian to run on the Xperia 10 III (codename pdx213).

## Status

### Device Tree Status

| Component | Status | sent to sm6350-mainline? | sent upstream? |
| --------- | ------ | ------------------------ | -------------- |
| ADSP | ✅ | ✅ | |
| Battery (percentage and temperature) | ✅ | ✅ | |
| Bluetooth | ✅ | ✅ | |
| Calls | | | |
| Camera | to do | | |
| CDSP | ✅ | ✅ | |
| Display Panel | ✅ | ✅ | |
| DP via USB-C | low priority | | |
| Fast Charging | to do, low priority | | |
| Fingerprint Reader | low priority, probably not supported by the kernel anyway | | |
| Flashlight | ✅ | ✅ | |
| GPS | | | |
| IPA | ✅ | ✅ | |
| microSD | ✅ | was already part of upstream | |
| Modem | ✅ (requires TA service to run) | ✅ | |
| NFC | to do, low priority | | |
| RTC | added, needs testing | ✅ | |
| Sound | to do | | |
| SMS | | | |
| Thermals | | | |
| Touch | occasionally does not work | was already part of upstream | |
| UFS | broken, need help | | |
| USB-C | ? | | |
| Wifi | ✅ (requires modem) | ✅ | |
| Vibration | to do, low priority | | |

No status means I haven't even had a look at that component.

So far no work has been put in supporting the sensors (accelerometer, magnetometer, ambient light, ...).

#### Where To Help

  - Audio/Calls <-- currently top priority, this would allow me testing the phone as a daily driver
  - Thermal Sensors / Thermal Zones (no idea what I need to do)
  - PMIC
  - Camera
  - vibration module
  - NFC
  - UFS
  - USB-C

And I will also need help with upstreaming the changes to the kernel, can someone else please do that? Thanks.

#### Kernel Work

I'll submit all my patches to https://github.com/sm6350-mainline/linux

Current goal: Making the device usable
Later goal: Trying to add everything else that can be added without writing new drivers and upstreaming

Note: I'm rebasing occasionally to make sure it does not become too chaotic, so pulling from that repo will lead to merge conflicts.   

### Issues To Solve

#### Touch

```
[   63.964541] gpi 900000.dma-controller: Error in Transaction
[   63.964562] geni_i2c 988000.i2c: DMA txn failed:3

[   64.601254] geni_i2c 988000.i2c: GPI transfer failed: -5
```

Occasionally stops working after logging in, no idea why.

#### Modem

```
[   50.440514] qcom_q6v5_pas 4080000.remoteproc: fatal error received: dog_hal_common.c:180:DOG detects stalled initialization, triage with IMAGE OWNER

```

Modem crashes. Reason is missing TA service. Modem works fine with TA service running.

Error message `[   50.440514] qcom_q6v5_pas 4080000.remoteproc: fatal error received: dog_hal_common.c:180:DOG detects stalled initialization, triage with IMAGE OWNER

Error message `[   50.440562] remoteproc remoteproc1: crash detected in modem: type fatal error` seems to come from https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/drivers/remoteproc/remoteproc_core.c?h=v6.19.12#n2707

### GPS

GPS likely also works via the modem. But the modem occasionally crashes:

```
[ 2792.695395] qcom_q6v5_pas 4080000.remoteproc: fatal error received: dog_hb.c:367:Task starvation: mmgsdi_1, ping: 4, triage with owner(d.dump 0x1ecf7180)
```

```
root@mobian:~# mmcli -m any --location-enable-gps-nmea 
error: couldn't setup location gathering: 'GDBus.Error:org.freedesktop.ModemManager1.Error.MobileEquipment.PhoneFailure: QMI protocol error: Couldn't enable location 'gps-nmea' gathering: Couldn't start GPS engine: QMI protocol error (46): 'GeneralError''
```


Needs investigation, lower priority than some other parts for now.

## Unlocked Achievements

- getting a first half broken Mobian build that boots
- getting the display to display stuff
- full graphics support (I can play an episode of Star Trek: Stange New Worlds, although without sound)
- playing a song via Bluetooth for the first time
- Wifi works! :D
- Modem starts

## Mobian Work

Not much that is required in terms of changes, mainly adding the device to Mobian recipes.

To Do:

- Push changes for Mobian recipes to git
- Add droid-juicer config
- Amend qcom-phone-utils package (initramfs hooks, perhaps more)
