[PROJECT][EXPERIMENTAL] Linux kernel 3.18.31 for Xiaomi Mi A1 (tissot)

cute_prince · Dec 2, 2017

Since Xiaomi has not released the kernel sources yet, I'm currently trying to port Redmi Note 4 (mido) kernel sources for Mi A1. The porting process may succeed because both these devices are based on same architecture and comes from the same manufacturer. I have shared my kernel sources and those who wanna contribute may send pull request to the same. I'm currently looking for testers and those who wants to volunteer please reply in this thread.

You can test with stock rom or TWRP recovery.
Steps for testing:
1. Download TWRP recovery / boot image of stock rom.
2. Unpack it and replace the prebuilt kernel with our testing kernel.
3. Repack it and reboot phone to fastboot mode.
4. Type fastboot boot <repacked_image_name.img>
5. If it boots, post here the dmesg and other helpful logs

Nah... doesn't boot.. while it's true that we share the same SD625 with many other xiaomi devices, there are other things to consider here... different display, camera, etc... not a kernel expert but just what i think...
anyway thanks for the attempt... i'm sure Xiaomi will release the sources soon, they might be waiting for Oreo since there are some specific commits that only apply to oreo, if so, they are actually kinda doing us a favor, since they always release the kernel once and never bother updating the sources since...

Yes I think it works. I've done it and boot on system, in system I have different kernel.
The stock is from 17/11/2017 and yours is 02/12/2017.
edit: fingerprint doesnt work
camera doesnt work (it opens but see only black screen)
led doesn't work

edit2: link dmesg https://mega.nz/#!JcBjjCSA!_xzviwYuyRBfOmmpx8eDPa9Q8Uvwn_uRu0Usx-w8Y1g
I dont know how to put it here so I've used my mega account, if have problem I can use google driver or dropbox

Odd... Didn't boot for me.. maybe I missed something

I see why the FP failed... the selinux is denied it, OP needs to set it to permissive

SevenSlevin · Dec 2, 2017

Normally with this kernel Can I boot in Miui rom from redmi note 4??

sooti · Dec 2, 2017

OK, got it to boot, great work OP! this could give us some lead until Xiaomi releases kernel source.

EDIT: so as I said earlier, selinux needs to be disabled for now... otherwise wifi, fingerprint, audio and LED don't work...

Wouldn't it make more sense to Port from Mi5X?

They are porting kernel source, Mi 5X kernel source isn't available either.

Great

. So it booted the stock rom. Did you tried disabling Selinux ? What about wifi, vibration, audio, bt, ir etc ? Are they working ?

Thanks for testing. Are they working (wifi, bt, ir, led etc) after disabling selinux ?

Oh wow Xioami is really slacking huh.

This is very good progress..thank u OP.i will try this out but could you tell me how much it will affect the performance?? If there any noticeable difference? Cause as it's a Redmi note 4 kernel the battery in rn4 is 4000mah.

They r slacking very badly..they have too many products rolled out & developer team size might not be that big it seems due to which many things r not happening in the right manner.

Send a screenshot..

Ya, no change. Selinux needs to be disabled on your end, add it to the defconfig.
WiFi, bt, it, led not working.
Vibrate and ril work

Ok. I'll push another build. B/w if you have Cpu-z installed can you check whether sensors are working ?

No problem. This kernel is using device tree file of Mi A1. So device specific configurations like battery, display etc are of Mi A1 itself.

SevenSlevin · Dec 3, 2017

don't work:
wifi, audio, camera, fingerprint, led notification, audio in jack earphones

work:
ril, ir, bluetooth, vibrate, audio in bluetooth earphones

I havent done nothing on Twrp recovery, I've just changed kernel like on description.

Hi, you have to symlink arch/arm/boot/dts/msm8953-qrd-sku3-d2.dtb file to arch/arm64/boot/dts/msm8953-qrd-sku3-d2.dtb
While pushing my sources, git ignored that symlink thats why build is failing for you.

As @sooti suggested I'll build another image with selinux disabled. Lets see if selinux is causing the issue. Also can you test whether sensors are working using cpu-z app ?
