[Loire] 3 amp chargers doesn't work

[maluus]

Platform: Loire Device: Kugo Kernel version: 4.9 Android version: 9.0

Description: Xperia X Compact doesn't charge with 3.0 amp fast chargers. 2.0, 2.1 amp chargers works. 1 amp chargers works till certain point and after that constantly cuts power after 44-45%. See attached log which includes both 3 amp and 1 amp (after 45%) charging attempts.

Symptoms: When charger connected at first begins to charge like 1 sec. then charging light goes off. Battery stat shows no charging but battery icon shows like charging.

How to reproduce: Connect 3 amp charger. Connect 1 amp charging until 44-45% logcat_12-16-2018_15-41-17.txt

can confirm the same problem on Suzu (loire)

[kholk]

The Loire platform does not support the new QuickCharge standard by hardware, so that's totally normal.

[maluus]

Which standards and what changed? It was working until the time when beta v3 binaries published.

Perhaps I don't understand the issue. Please post a dmesg. The logcat is pretty useless here :P

I can guess, around the v3 release the kernel was updated, maybe something went wrong.

[maluus]

OP updated. You can find dmesg in the first post.

[jerpelea]

this platform should not support the feature!

[harryharryharry]

@jerpelea According to Sony's own website Sony X Compact does support QC3.0: https://support.sonymobile.com/us/xperiaxcompact/faq/battery,-power-&-charging/02310188014550f700148fcce243e002e57/

[maluus]

Sure it supports because my phone came with a qc3 charger out of the box. But I think it's to do with 4.9 kernel. Because it was working with 4.4 kernel even with pie.

Iirc even suzu supports it. At least, in stock 6.0 fw... And in 2016 white papers

[kholk]

Wait a minute. I think we have to reopen this issue.

The QC3.0 - supported or not - is an evolution of QC2.0, so on an unsupported platform it should anyway charge the device, even if it falls back to a lower amperage... but the device is not charging at all.

This is a bug.

I'll look at it whenever I'll get some time to.

[harryharryharry]

Thanks. You're right, on kugo stock and even omnirom 8.1 do indeed work, although at a lower amperage (~1 to 1.5 as I recall). But omnirom 9: crickets chirping (only the led indicator goes on for about 2 seconds)

[maluus]

As I stated in my previous posts if its not something that 4.9 kernel restricts somehow then it should normally fully benefit from qc3. I had just thought over jerpeleas statement that for some reason 4.9 kernel restricts qc3 working on loire. Anyway I had given up builds and tests after jerpeleas comment but although the problem exists for all the loire users, if needed I can start to build, test and provide necessary logs.

[jerpelea]

please provide logs from 8.1 and 9.0 to speedup the investigation

[harryharryharry]

I've saved dmesg-snippets during cable attachment to a qc3 charger from stock and omni8.

dmesg-snippet from stock (F5321 34.4.A.2.118) with genesis kernel (to get root): https://del.dog/ucikonogim

dmesg-snippet from omni8: https://del.dog/uqalaqojus

And this is a full dmesg I just took from omni9: https://del.dog/yagiqonovo

[maluus]

9.0 logs are in first post. You can find attached 8.0 stock rom dmesg log. I plugged in and out a few times before taking the log.

This issue still exists on Suzu, phone can't charge with a QC3.0 charger at all. AOSP build on 2019.2.8 with OEM V5. @jerpelea

[maluus]

Lots of commits and merges lately. Is there a possibility that some of them somehow affects this issue? [Late edit] @kholk

Issue still exists on Android 9, OEM V7, built on 2019.3.23. My charger is UCH10, only support QC2.0. SuzuCharge.log

Log uploaded.

[maluus]

I think devs couldn't have time to look at the problem yet. Fingers crossed.

[harryharryharry]

@maluus, Pavel recently made a commit that fixes this issue: https://github.com/bartcubbins/kernel_loire/commit/2b5fdc84600620e8ae146a7c888f7c9ebfbe397d

My kugo now charges at 2A with a QC3 charger. Thanks @bartcubbins !

[maluus]

Oh at long last. I can start building again.

[bartcubbins]

@jerpelea fixed by https://github.com/sonyxperiadev/kernel/pull/1972

[maluus]

@harryharryharry, Today I synced the source and built but problem persist on my side. Did you cherry picked the commit or compiled directly from the source? I'll check it again soon.

[harryharryharry]

Since it was such a small modification, I dumbly added the line in the commit to the appropriate place in msm8956-loire-common.dtsi in my sources. Only syncing your sources will not be enough, since this is still just a commit from a repo from Pavel's github. So either manually add it or cherry-pick the commit from Pavel's repo.

[maluus]

I checked that the code is there and rebuilt but problem persists for me. Tried with both proprietary and genetic QC3 chargers. @bartcubbins, @jerpelea, @harryharryharry,

[bartcubbins]

just tried and can't reproduce the issue anymore

[bartcubbins]

please, provide me dmesg and I will take a look as soon as possible

[maluus]

Dmesg attached. I hope it helps. I plugged it in different chargers and pc before taking the log. (proprietary qc3 charger, other generic qc3 charger, and ipad charger and pc.)

dmesg.txt

[bartcubbins]

@maluus please update your kernel. you have outdated kernel. (HEAD 96e6d64d2d0c) https://github.com/sonyxperiadev/kernel/commit/96e6d64d2d0cda43e77ef5274bd1118362c1d0c2 [ 0.000000] Linux version 4.9.170-g96e6d64d2d0c-dirty

[bartcubbins]

@maluus looks like you use prebuilt kernel. change this to true and try once again https://github.com/sonyxperiadev/vendor-sony-kernel/blob/aosp/LE.UM.2.3.2.r1.4/KernelConfig.mk#L15

[maluus]

It's ok now. Problem seems solved. But I have a question. What's preventing it benefiting full QC3 charging capability?

[bartcubbins]

@maluus due to SoC HW limitations. @jerpelea I think this issue can be closed after updating prebuilt kernel

[kholk]

@bartcubbins that was great man, thanks :D

[bartcubbins]

@kholk 😉

[maluus]

I forgot to thank for all your valuable efforts @kholk @jerpelea @bartcubbins @harryharryharry
