[Q] About kernels

Hi, I'm kind of new to this rooting thing and I have a few questions! My maguro GNex is running CM 10.1 with the latest nightly at the moment, and I wanted to know what are the so called kernels, and what can I do with it, where can I get a good one and so on.
Thank you in advance!

Kernel is somekind like the brain of the ROM. There is a lot of nice kernel for maguro such as trinity, franco, lean, etc. Read it in the development section and try it to find the best for you. For me, the best is Trinity kernel.

Not all the info in that post is correct. The stock kernel *does* adapt voltages and frequencies based on demand. To understand what a kernel does, I find it helpful to view the architectural design:

that really cleared up a lot of questions i had about kernals, do the dev's in charge of certain roms pick the kernel that works best?

they usually compile their own, use a friends, use the aosp kernel, or use their favorite

I usually check for features I'm looking for when selecting a kernel. I always try to find one that has fast charge option cause I'm impatient when it comes to charging. Available governor's and color change options are important too.

use an AC charger? ....

Culprit possibly found for 4.2.x lag ? "Lagfix" inside

I thought this was maybe worth making a topic for so we could report together what experiences are on this..

I'm surprised that this actually works! The speed all around has improved and the lag that I used to have when updating apps is gone! That lag made the phone unusable for me. Glad its not happening anymore.

Somebody should make a flashable "lagfix" zipfile for this. That would be practical.
Anyways I'm testing the new heapsizes out too, will report later. I'd like to hear what a dev thinks about this too.

Only changed the values via build prop editor a few minutes ago so need some time to determine wether it does something or not.
Do any of you know more about this ? Tried it ? Maybe a dev can give us some more insight ?

Yawn, this was posted in the other thread already.

Not at all, it's just annoying to see 3 threads with moaning about 4.2.2 and every new magic buttery fix that comes weekly.

I'm trying that "fix" from some days, and do you want a true and honest opinion?
It doesn't produce any difference at all.
Probably and theoretically with that fix you should have more free ram when you opened a lots of heavy apps during a day, but it is not cause any real benefits
How people can say that with the fix you don't notice lags when installing apps? That's impossible to solve by changing heap grow limit.
On android right after the app is installed, the system generate the dex "executable" file in the dalvik cache..that is a particular "heavy" operations, as today mobile hardware, and always caused the system to lags on that occasion
Every Operating System "lags" in certain conditions, more or less. The more you use it, the more you see its limits.

** Reddcoin | The Social Currency **

Hi there,
Let me introduce myself for starters. I'm a devoted Nexus & Android user and I'm using XDA for a couple of years now. One of the moderators (/u/rwest05 on Reddit) from this thread gave me permission to post this, so do not consider this as spam
Recently I started to develop my interest for crypto currency. Nowadays I'm involved in the Reddcoin team. Reddcoin is a coin (like bitcoin) mainly focussed on tipping. Reddcoin can be bought or mined using CPU, GPU or the more recent ASIC. Soon Reddcoin will switch to a new self developed system called PosV*. For all technical questions I want to refer to our FAQ* and if I got you attention be sure to also take a look at our website*.
What I'm trying to find out if the XDA community would like to implement (or for starters use) Reddcoin as their main crypto currency. We already have tip bots on Twitch*, Twitter, Reddit and soon IRC (#reddcoin on freenode). Reddcoin also has it's own API*.
So now you guys are wondering. What are the benefits for me in all of this. For starters Reddcoin has it’s own Broadcast* platform. So for instance if any of the XDA devs wants to announce something, they can use our platform for free to have maximum social reach. Second is that people can tip each other Reddcoins as appreciation for their work. And last but not least we have a light Reddcoin Android wallet (also available in the Play Store) that can be included in any custom rom.
Please let me know what you guys think. You can also PM me if you want to get either involved with Reddcoin, mining or both.
Cheers,
Lowww

No problem. Everyone is free to choose

I love the ReddCoin. I also hold many other coins, including Doge.
I created ReddAPI. If you have any questions, you can contact me about the API.
The API has an app competition going on right now.
The Reddit community will be voting on the winner. 1st place gets 5 million coins, that's [130.00] (now its 155 but when the value hits 7 sat, its 180.00) USD today, and hopefully much more later this year.
Big things are coming to ReddCoin. Keep a weather eye on the horizon.

yu yureka support [KERENEL] THE GREEN MACHINE

Please, don't be intimidated by any techy lingo, the second paragraph will have a quick rundown for non devs!
Hey all! @YoshiShaPow and I need a little help selecting the toolchain to use for official releases! Currently, we are using a GNUEABI Linaro toolchain optimized for Cortex A15 processors. But, as shown in a recent test (similar to this one) conducted by Chet Kener (@Cl3Kener), GNUEABI toolchains have worse performance and battery life in comparison to their ARM-EABI counterparts. The tree toolchains that I have compiled are Linaro, and (what I refer to as LinaroMod and SaberNaro) 2 hybrid SM and Linaro toolchains.
What does this mean for you?
I have compiled three toolchains to use for the kernel. We need you to help test the kernels to find what is best for the official releases of the kernel. Below are the requirements for the test (Copied from Chet's toolchain war)
1. You must flash both kernels on the SAME ROM and should spend at least a day on each
(but 2 or 3 days would be best if you can, this is not a quick fight this is all out toolchain war!)
2. You must keep track of battery life as best as possible.
Take screenshots of you SOT, Stand by, voice calls, other apps you think are significant. I will be posting a short questionnaire/survey where I expect you to have some details on battery life. I don't need to see all of your screenshots but you are welcome to post them all here in this community for us to all see.
3. Try and to keep track of performance the best you can
Obviously I don't want you to shy away from benchmarks. By all means run as many of them as you like. I also understand that benchmarks don't always give the whole picture on performance so I'm also looking for you to describe any differences you see between these three kernels. Comparison and contrast are the preferred method. (ie. This one opens camera app faster than that one. This one has smoother scrolling than that one. This one has a more fluid UI than that one. etc.)
4. Look for anything else that is measurable that you can test
Test boot times, test app opening times on large apps like Facebook. Look for operations that cause lag on the kernel and try to reproduce the lag doing the same thing on the other etc.
5 Most importantly have fun and keep track of your observations!
If this isn't going to help make your week more enjoyable don't participate. I'm not trying to ruin your week.

Joe Maples Answer for me .
Porting a kernel isnt like porting a rom, it doesnt work that way. If you can get more people to request it though, Ill make a green machine version for it.

Question best oneplus 9 pro module for battery saving

With this module ru one plus I will be better without spending so much battery and not getting hot The latest version is DEV version 21.07.25 but I use DEV 21.05.23 it saves my battery and in games it does not heat up, try to see which one you have left better and post it if it worked for you.

Why do you use a module that is intended for certain SoC's with one that is not even supported? The OnePlus 9 Pro has a Snapdragon 888. The highest version according to the GitHub site is 865.
Or what am I missing here?
