Is there any chance this kernel will fix screen flashing/blinking after installing 75 hz mod?
It flashes/blinks after waking from sleep.

Is it possible to include Wireguard in the kernel?
Maybe next time ?

any news about android 10 kernel?:highfive:
Hmmm ? no news yet ?

My guess that it'll come with Deepest 10. Just a guess, no inside info. :)
Looks like someone haxxed my cloud server ?

Just kidding, Idk either about that.
There's still no working Quiche device sources for grus (or even sdm71x in general) that has been published on github/gitlab and works quite well.
So definitely still no upcoming news about derpfest 10 for grus either :rolleyes:

Let's hope that when you are allowed to unlock the bootloader there's a Q version of the kernel. I miss it.

Ms Okita, actually. :p

Hi there ms. Okita, hope you are doing well.
By the way for the last 2 weeks, I've been using 8.4 version on MIUI 10 xiaomi.eu dev. The kernel running good but sometimes after few restart, the sound crash and all apps that produce sound opened (play video on YouTube, etc), the phone hangs and freeze for sometimes and need to force stop the apps.
Also sometimes, the camera crash and cannot opened, but it's rarely happened.
If this problem occurred, I need to restart my phone several times to get normal.

I just want to inform you, maybe you can explain few words or fix the problem for future update.
Thank you so much.

Wow, I just saw that this kernel it's working even on miui weeklys (betas) again. I thought that it only works for GSI ROMs.
Unfortunately, I am on Android 10, guess I have to wait a bit to test.

This would be nice. Stable or Okita conform :) ?
Battery is terrible with Android 10 and Miui11

sorry I've been busy lately, maybe you need to clean dalvik-cache especially after updating os.

my kernel do run on miui but doesn't mean 100% compatible with miui (some codes isn't yet published/updated by xiaomi), so there's some compromise happening here :)

    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) :)
