# 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? |
| --------- | ------ | ------------------------ |
| 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 UFS, but for testing I could work around this) | ✅ |
| 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

  - 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'm currently working here: https://github.com/erebion/linux/commits/pdx213-wip/

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

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
[   63.964594] geni_i2c 988000.i2c: GPI transfer failed: -5
[   63.966484] s6sy761 0-0048: failed to turn off sensing

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

Occasionally stops working after logging in, no idea why.

#### Modem

```

```

Modem crashes. Reason is unknown 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

## 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)
