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)

Haven't been able to figure out what's wrong.

Debugging Touch

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
Bluetooth	debugging
Camera	to do
CDSP	✅
Display Panel	✅	true
Fast Charging	to do, low priority
Fingerprint Reader	to do
Flashlight	✅	true
IPA	✅
Modem	to do, requires UFS
NFC	to do, low priority
PMIC
RTC	to do
Sound	to do
Thermals
Touch	occasionally does not work	was already part of upstream
UFS	broken, need help
USB-C
Wifi	added, but requires modem as well
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
• USB-C
• Camera
• fast charging stuff
• 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
