Hello,

I started making kernel builds again.

CHECK BELOW FOR IMPORTANT INFORMATION!

YOU MUST USE MIUI Q FIRMWARE PACKAGE FOR THIS KERNEL TO WORK. OTHERWISE YOU'LL END UP IN FASTBOOT MODE FOREVER.
Camera won't work on a lot of ROMs due to imcompatible camera drivers in the kernel. This kernel uses a patch for MIUI Stable 11.0.4 release, which introduced updated camera blobs back in Android Pie. Double check, whether your ROM uses these blobs. MIUI Q uses different blobs too, thus won't work until Xiaomi releases it's kernel source code.

FLASH THIS BEFORE FLASHING MY KERNEL. I UPLOADED FIRMWARE PACKAGE FOR YOUR CONVENIECE!

DOWNLOAD LINK FOR MIUI Q FIRMWARE PACKAGE

Flashing procedure is standard - through recovery. Magisk is optional, only if you want root.

*big thanks to rama982 for possible insights and some help from his side*
*nathanchance for android-linux stable and helping upstream our kernels*
*franciscofranco for commits that made our phone happier and snappier*
*sultanxda for his beastly development in Android scene and ridiculous understandment in kernels in general*
*also thanks to osm0sis for Anykernel3. Without this, flashing kernels would be a harder process to do*

DOWNLOAD LINK FOR GITHUB RELEASES

Due to different kernel base, older releases are irrelevant from now on.

UPDATE: I added a link for MIUI Q firmware package in the OP. Check it out and remember to flash it first before flashing my kernel. Thanks.

-------------------------------CHANGELOG------------------------------

Jelly Kernel Alpha 1.1.1 Hotfix

ALSA: pcm: Add missing copy ops check before clearing buffer (bootloop after voip videocall should be gone now)


-----------------------------------------------------------------------------------------

Jelly Kernel Alpha 1.1 beta release

IMPORTANT INFO! Camera won't work on a lot of ROMs due to imcompatible camera drivers in the kernel. This kernel uses a patch for MIUI Stable 11.0.4 release, which introduced updated camera blobs back in Android Pie. Double check, whether your ROM uses these blobs. MIUI Q uses different blobs, thus won't work until Xiaomi releases it's kernel source code.
If this kernel is not booting for you (going straight to fastboot mode), you need to use MIUI Q firmware package.

Changelog:
*Bringup for Clang 10 and it's now compiled with Clang 10
*Using LZ4 compression for zRAM
*Forcefully load modules (this should fix Wi-Fi problems on various ROMs)
*Rapid GC for F2FS filesystem
*Added fsync and crc check switches
*kgsl fixes and optimizations included
*Introduce additional NEON accelerated arm64 routines
*cfq io scheduler fixes and optimizations
*Tick rate increased to 300HZ for improved responsiveness
*CPU mask affinity set to 4 cores for improved efficiency
*Enabled F2FS filesystem support with encryption
*F2FS fixes
*Increased slmk's aggression rate to 192MB per app kill
*Enabled Dolby DS2 audio standard
*And more I don't really remember, check commit history for more detailed changes


-----------------------------------------------------------------------------------------

Jelly Kernel Alpha 1.0 beta release (don't use this release, it's deprecated)

*Complete rebase on jasmine's Q tag.
*Linux 4.4.211
*Adrenoboost enabled and set on low parameter
*Workqueques reworked for better responsiveness and lower power consumption
*Small UV for both CPU and GPU
*CPU Bitmasking
*DTB debloat (reduced kernel's footprint)
*LA.UM.8.2.r2-00600-sdm660.0 CAF tag
*Using older Wi-Fi CAF tag for better down/up speeds
And more stuff I don't remember.


-----------------------------------------------------------------------------------------

DISCLAIMER:
-There will be 1-3 kernel builds per week, unless there's nothing I can improve, then builds will be as is.
-Anyone, who has tested it already, give me some feedback in the comments.
-If you get freezes, crashes, restarts, write me up with a attached dmesg, log, anything, that can give me a clue what's wrong. Thanks. Happy JellyKernel'ing ^^

Use the browser - there's a section DOWNLOADS above the thread. There you will find my kernel build. Cheers.

Yes it does. Look up using kernel manager.

Is the any chance to get the turbo frequencies on the GPU?
I read that on some other page I can't remember where, can you please why that supposed frequency is not on the stock kernels, does it take to much energy?

I believe Qcom left off this frequency just because CPU is already close to some of their flagship SOCs in terms of CPU performance.
Everything in the source code is left done, you just need to modify a code a bit and you have higher frequency. If you want to go any higher, you would need to modify the code a lot more. Tried it and gave up on that.
It could be anything, really.
Moreover, you don't see too many phones using this exact SOC.

P.S. Funny thing though, this OC feels like placebo effect, like CPU is running faster but it's really not.

Think about it, when sdm660 came out, it was between SD821 and SD835 in terms of CPU performance. GPU is more or less the same as Adreno 430.
