Thanks okita, love your work!! Accubattery is saying there is a task killer interfering with measurements, but I don't have one. Is this a kernel optimization thing or something to do with crdroid?

v8.3 R3 is up and deep-sleep issues should be fixed in it, umu.

Thanks a lot for your work.
The version 8.3 R2 definitely fixes the only problem I had with bluetooth in previous versions.
It happened that the Bluetooth connection with my car was established successfully but after a few seconds the message "emergency calls only" was shown. Everything worked as expected but the signal was not properly displayed.
Now everything is perfect.

You're welcome.
This kernel uses stock lowmemorykiller from Google, no fancy version.

Glad to hear that, probably it get fixed from the Linux upstream itself.

Anyways, anyone's uses the latest kernel on MIUI 11 android 10 ?
I can't try it yet due to some businesses stuff, so any feedback would be great especially If there's anything wrong with it ?

Hi @okitavera, for long time I've been using v6.1 on miui 10. By now since okita kernel support miui again, I wanna update the kernel, but I have a question. Does the magisk add on still compatible with the new version kernel?
Thanks.

That's why backup boot and dtbo is necessary.

So the only thing is just wait for xiaomi to update the kernel source, which is great since we didn't get a source update from xiaomi since 6-7 months ago [emoji23]
I backuped boot and dbo, after restore that, device was booting into fastboot. Anyway, no problem, some important media gone [emoji14]

I am wondering: You, as dev, cant do anything to set compatibility with Q? No compatibility will be harm and imo better have kernel on P than Q without kernel.

It's already booted on aosp Q, but not with this miui.
And that's pretty common since miui is just too far from aosp.

there is a chance to boot by rebase/merging la.um.8.8-r1 but I still want to play and rank up my games, and chill for a bit of time xd

Haha. That's ok. If you may try to do something to match it up with Miui Q - we will wait patiently and be grateful. Anyway, take some virtual chocolates for your involve to improve this device. Have a good day :highfive:

    Breaking news.

    Xiaomi already publish the Mi A3 (or Mi CC9, CC9 Meitu, whatever you named it, Xiaomi) Kernel source code.
    It basically uses the same base as ours, and after some hours of inspection,
    me and @pengus77 got a few things from Mi A3 and Mi 9 source code that can be ported to fix several issues on this device (like the brightness, fod, etc) :)
