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

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

Occasionally stops working after logging in, no idea why.

Modem

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 seems to come from drivers/remoteproc/qcom_q6v5.c, see https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/drivers/remoteproc/qcom_q6v5.c?h=v6.19.12#n126

GPS

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

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)

Building the Kernel .deb

make defconfig pdx213_defconfig usb-gadget-network.config
make -j`nproc` bindeb-pkg

Obtaining firmware files

This should normally happen automatically using droid-juicer on first boot, however, as UFS is not supported yet, we have to boot a working system and obtain the files manually for now.

Easiest way to do that is to use SailfishOS. The licence is not required, the trial image works just fine.

Firmware files can be obtained from the partitions modem, vendor, bluetooth...

Recommendation:

• dump partitions to .img files
• mount .img files and extract files
• use pil-squasher to get the files into the right format the kernel expects

Building the Image

Clone my fork of mobian-recipes (temporary fork, will integrate changes once I get to it...)

git clone https://salsa.debian.org/erebion/mobian-recipes
git checkout wip/erebion/add-pdx213

Place kernel .deb at devices/qcom/packages/

Put firmware files into devices/qcom/firmware/, this currently what I have in there:
