Undervolted kernel

[Cozzmy13]

Cozzmy13, of cource. File, that is needed to upgrade is on page 1. But if you want see voltages, there another two files to change. If interesting, tomorrow I'll write that.

I wish I knew kernel programming.
Anyway, I can add a sysfs interface from another similar device, I've seen multiple.

how to compile it with another boot.img?
it seem so interesting, but my knowledge, just rooting

Ok, finally I compile that. Results are impressive. So A53 UV up to 0.97V, A57 up to 0.93V(at max frequencies). Geekbench and GFXbench phone pass. No any stutter. At lower voltages receive boot loop. Sorry if someone want to test, I don't have 10 posts yet to include external links. No more needed underclock CPU.
Also now I have another problem, in some games main overheating come from GPU(own power from GPU=4W). I searching how UV it, but w/o luck. If someone can help links or some other stuff.

Hi this look like a possible solution for our device thermal problem. Could you compile undervolt module for LoS 15.1 by Cozzmy? Or if its too much, may I ask how you implemented in the kernel itself?

I dont know my cpu binning level but hopefully it would be stable at those voltages.

Here is the link with kernel

Well, I couldn't pass a MI logo , tested on Lineage OS 15 and AOSP Extended 4.6

I think that one is for LoS 14.1.

Hi! There is no longer any need to tinker. HnT has laid out the LOS 14.1 with the interface for kernel adiutor. Unfortunately there is no separate kernel. But there are sources for all interested. Firmware on 4pda: https://4pda.ru/forum/index.php?showtopic=697094&st=12240#entry66527898, kernel source https://github.com/LineageOS-eXtended/android_kernel_xiaomi_msm8992.
I apologize for the fact that so long did not write to the forum. I thought this topic is of no interest to anyone.
