This is the new stable release for POCO F2 Pro, POCO F3/Mi 11x

Changelog:

• Fixed support for MIUI (Only F2 Pro bug)
• workqueue: queue everything on system's power efficient wq (b3c8b86)
• Remove again minimum frequencies (004b21a) it will not drain more due to energy improvements.
• lib/string general optimization backported from linux-next
• arm64 low level optimizations from linux-next
• char general optimizations

In general, this build should improve performance without the compromise of battery drain.

Benchmark:
Hackbench from 2.323s to 2.192s ( $ hackbench -pTl 4000)

NOTES:

• Flashing the kernel can be done on your favorite recovery or using @xzr467706992 Horizon Kernel Flasher: https://github.com/xzr467706992/HorizonKernelFlasher/releases (POCO F2 Pro only)

Support:

• Through issues tab
• https://t.me/aicplmi
• Respective XDA Thread.

logcat and or dmesg is mandatory for support regardless.

• Much more stuff from previous beta rolled on my tg channel (https://t.me/QuanticKernelLMI)

NOTES:

• This kernel works much better on AOSP ROMs specially the ones built with AIDL libperfmgr such as Descendant 11.5 and PE+
• For alioth users in case kernel don't boot, please flash the dtbo attached by using '$ fastboot flash dtbo_a dtbo.img'
  Flashing the kernel can be done on your favorite recovery or using @xzr467706992 Horizon Kernel Flasher: https://github.com/xzr467706992/HorizonKernelFlasher/releases
