Ya, I’m back now 🙂

Major features

Fully rebased kernel with cleaned-up OEM changes, built with latest GCC toolchain
Pure PELT implementation with all redundant boosting nuked
BBRv1 + fq_codel as the default TCP network congestion control / queue management
Better memory management brought by simple LMK, optimized zRAM, etc.
Optimized battery draining with smoother UX
mainline exFAT driver, WireGuard kernel module support

Disclaimer

This kramel is expected to work on Xiaomeme-UI 12.0.x stable (Android Q) and TH779’s (un)official builds.

hello man,
kindly asking, is it possible via kernel to raise bluetooth mtu to 512?

dhaern

Hii man, thanks for your project, it’s very appreciated and needed for K30 Pro. I would like to know if you can add support/feature for overclock screen like K30 Ultra or Mi 10.

We are trying do it but no luck atm unpacking dtbo.img and changing clockrate/framerate parameters with an small custom linux unpack tool. Check our thread here please:

Thanks.

Also what do you think about this new “kernel optimizer” KTweak? can you merge the features there with your kernel if it’s worth to do it?? Here you have the KTweak optimizer xda link:

Sorry, but I know little about this.

#6 @dhaern
Screen oc is not a good idea, for the higher clkrate should do harm to the panel.
However I tend to leave the choice to user. This feature will be introduced after several versions.

#7 @dhaern
Well, actually tytydraco has done something impressive,
but that’s not to say that we should always follow his ideas.

The following comment is from Park Ju Hyung (arter97) for reference only.

alk3p Glad to see you will add screen OC refresh rate feature to “TO DO” list, I hope we will see it for android 11 builds. I get it can harm the panel but having the choice is good because many people want test or use it because we have a feeling about this device underperforming vs other top devices like mi 10 or k30 ultra or oneplus devices, same with the mono speaker audio.

Thanks about the Ktweak info, Im using it atm and I will uninstall when your kernel will be ready and stable.

Thank you so much for developing a kernel for the K30 Pro.
I saw on your github page that you are working on a Lineage 17.1 ROM. Is it going to be GSI-based?
Thanks again!

#12 @murilotdb

GSI would be a fallback option if I failed to make it work with proprietary blobs.
btw recently I’m too busy to spend much time on it, so…

#13 @dhaern

Well, it seems a bit difficult to oc refresh rate, for it’s not so easy as I thought previously.
Anyway, I’ll try my best to do it.

#14 @hyperionx7

Could you provide more information (e.g. screenshots, detailed description, etc.) ?
Thanks.

k30pro 908版内核bug 版本稳定版12.0.4 ：播放斗鱼直播无法横屏播放，会出现一种奇怪的画面比例，以至无法使用，复现概率百分百。xda上也有网友说12.0.8上youtube也会出现这样的情况，恢复官方内核后正常。
