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

[   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/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.

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.

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

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
