# pdx213-temp

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

## Status

- amending Device Tree
- porting Mobian

### To Do

- getting remaining hardware working (incomplete list)

#### Debugging 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
[   64.599984] gpi 900000.dma-controller: Error in Transaction
[   64.600041] 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.

### Done

- 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)

## Kernel Work

I'm currently working here: https://github.com/sm6350-mainline/linux/pull/1

Current goal is just to get a somewhat usable phone, then tidying everything up and trying to support everything else that I can support 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.   

### Device Tree Status

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

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

I'll need help for:
  - Thermal Sensors / Thermal Zones (no idea what I need to do)
  - PMIC
  - Camera
  - vibration module
  - NFC

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

(highest priority first)

## Mobian Work

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

To Do: Push changes to git
