can someone explain this Kernel stuff - myTouch 4G Q&A, Help & Troubleshooting

I rooted my MY4G and installed IG last week...nothing else..i have added some little stuff like setCPU, terminal emulator, etc.
I keep reading about dif Kernels and i have no idea if i need to install one or what they do over the ice glacier i all ready installed.
explain all this too me please.
thanks

Different kernels just have different features. The stock kernel that comes with Iced Glacier is already a custom kernel (Gr8Gorilla's 1.8 GHz v.05). If I remember right, this kernel didn't have UV (Under Volting). There are many different features offered with each kernel choice. Such as:
OC (Over Clocking support): This just allows you to go higher than the factory settings.
UV (Under Volting): This means the kernel's voltage tables have been lowered to attempt to save battery life.
MinMax: This feature keeps the CPU running at the set minimum and maximum settings.
Smartass: Scales the CPU "intelligently." It acts in lieu of SetCPU profiles by scaling the processor down for screen off.
There are also different scaling types enabled in different kernels. Just give them a flash to see if you like them! Make sure you remember to do a nandroid first. Happy flashing!

[Q] faux's kernel or cyanogenmod 7 rc3's stock kernel?

I'm torn between the two kernel's. Through your own experience, which kernel is better for performance and which for battery life? with the cm7 stock kernel i can get around 2700 in quadrant at 1.5ghz but i heard people were getting scores in the 3000's with the faux kernel?
Any help would be greatly appreciated!
P.S. why do i seem to get lower scores on performance governor than ondemand?
Faux is what I use. Don't base your phone on quadrant. Its like cake. Looks delucous.. but the cake is a lie.
Its a general idea of a phones performance.. not the end all be all.
Both work well... but faux has newer wifi drivers that greatly increase range and performance.

as stated above Quadrant Standard is just a starting point. It lead nothing to the true facts of how well a phone preforms.
Couple of things to consider.
1) Zinx has created CM7 around the kernel that is installed with the ROM. If you need help you will get more help directly from the developer using their kernels, This goes for any ROM.
2) If you opt'd into the feedback program you will be doing so with false information. You'll be giving feedback based on "product a" when in all honesty your using "product b"
3) overclocking the phone is not always the best thing to do. Sure it's nice to show off and say "hey looky what i can do" but when the rubber meets the road their is no real benefit other than cooking the battery. And keep in mind what happens to things when they get hot, they expand. And when you are pumping that much extra into and out of a processor they will expand which will wear and tear on the motherboard and solder joints.
Personally i'd just keep the stock kernel @ keep it at most 1017 unless you plan on showing off, then moving back ASAP. and for what it's worth i typically run my MyTouch @ 768Mhz.
neid, 2 questions!
1. I want to underclock to 768 as well (never messed with CPU settings before) on CM7 RC3 using the system built in setting not set cpu, have you seen any performance degradation?
2. when I revert back to stock from my nandroid, would the CPU be throttled back to default settings or will it stay at 768?
Thanks

1) on my phone, i use 768Mhz day in and day out, Fruit Ninja, Angry birds, Browser, dialer, navigating the phone in general everything performs EXTREMELY well. I've not had any complaints. just go to settings > cyanogen > performance > CPU > max > 768. Since Cyanogen is a lightweight ROM it doesn't have to push though all the bloat that MySense brings so we can scale it back and still get good results.
i personally do not care for Quadrant scores. but i know some people live by them so i've attacthed a 768Mhrz and a 1016Mhrz Quad score. The names will be the set speed.
2) the CPU speed will revert back to what ever you have it set as on that ROM. So if you left it 1017 in your Nanadroid it'll be 1017 when you flash the restore.

[Arrows - Guide] Best Aosp GB & ICS Roms [Updated - 1/22/12]

Feel Free to post and give feedback ^_^
Also feel free to Vote the thread ^_^
Q&A is in Post 2
_____________________________________
Hi Everyone, Arrow here and this is my guide to find what is the best aosp setup for your evo or android. It is true when people say "every phone is different." However there is an average of people that get similar results. At the moment people have different interest such as some people want performance and some want to improve their battery life. Of course certain people want both but only some get both.
*Remember what i put here is an average and may be different on your evo*
AOSP GB ROM'S: Ok so to start off, these are aosp roms still being updated as of now.
CyanogenMod 7 (CM7) - The most famous aosp rom out there, all or almost all other aosp roms are based off of this rom. This rom has a stable rom and experimental nightly builds. Anyone will tell you that you can't go wrong by choosing this rom. and believe me you will enjoy it.
CyanogenMod 7 Thread
Miui - This rom has the longest battery life and is very customizable. This rom is based off of CM7 and is an excelent rom. However unlike CM7 this rom does not have 4g so if you are willing to sacrifice 4g then believe me this is your rom.
Miui Thread
Gingerbread Evo Deck - Ok so although CM7 is amazing decks gb rom has said to be the exact same thing but giving off better battery life. other then that it is pretty much the same thing with some minor tweaks and some bloat ware removed.
Gingerbread-Evo-Deck's Thread
Xplod E4G - Team Nocturnal designed this rom and it is pretty much CM7 with the Sony Launcher + their apps. This rom will give your phone a nice cool feel that other people don't have. If you like a lot of eye candy then get this rom because it is CM7 just with a different look and feel.
Team Nocturnals Xplod E4G RLS1.2

using Xplod: there's a 50/50 chance the new tiamat kernels [4.0.7+] may not boot, in that case, they should use 3.3.7.
Click to expand...
Click to collapse
ICS(mod7) - Team Blaze designed this rom and you can consider this rom like Xplod E4G, a rom just like CM7 with some minor tweaks but with a different look and feel. None the less this rom has something very special this is the closest rom to being like ICS (Ice Cream Sandwich). I 100% support this rom because they are doing the best they can to make this rom look and run as smooth as ICS. so if you want to look like your ahead of the game definitely get this rom.
ICS(mod7) Thread
AOSP GB Kernels: These are three kernels that i know of, if you know of more please let me know and i will add them.
Tiamat 4.1.0 - This is the latest kernel made by Tiamat and this is the only aosp kernel still being updated. This kernel on average gives people great performance but lacks on battery life. The main Governor for this kernel is SmartassV2 which is a balanced governor, good to turn on your phone and good to use on a normal day to day bases. For this kernel i do recommend using this governor. It does have SBC and Non-SBC kernels. *Side Note* (Some people say Tiamat 3.3.7 works better for them and is also known as the LEE Kernel because it was awesome like Bruce Lee and looks like Lee backwards [337])
Tiamat Website I also put the Zips in the Attachment (At The Bottom)
Savaged-Zen - This kernel is no longer being updated, however it is still amazing this kernel seems to be Tiamat's competition. Where Tiamat lacks on battery Savaged-Zen does not. However it's performance is not as good as Tiamat. This Kernel comes in two version BFS (Brain F***ed Scheduler) and CFS (Completely Fair Scheduler). BFS is said to give better performance and CFS is the normal kernel. This kernel only comes with SBC however you may download "SVZ Manager" which will allow you to turn SBC on or off. The main governor for this kernel i believe is on demand However i use smartass and a lot of people us InteractiveX.
Savaged-Zen CFS sbc I also put the Zips in the Attachment (At The Bottom)
Savaged-Zen BFS sbc in attachments (At The Bottom)
SVZ Manager I also put the Zips in the Attachment (At The Bottom)
GoDm0de - This Kernel was made by toastcfh and is no longer being updated. It is non-sbc and in my opinion definitely the best non-sbc kernel. This Kernel has insane battery life and a pretty good performance. If you do not want to use an sbc kernel i recommend for you to 100% use this kernel. The Governor for this kernel is set on on demand (i think) however i got the best battery/performance using Interactive.
GoDm0dE Kernel I also put the Zips in the Attachment (At The Bottom)
AOSP ICS ROM'S:
ICS rom by: the_Plattypus and it is still in Alpha testing. however the development for this rom is moving really fast so hopefully a beta will come soon.
EVO 4g Ice Cream Sandwich from source
ICS-evo-deck: This Rom is by kushdeck, After testing out Decks ICS Pre-Alpha 4 & 7 rom i conclude that although it is a alpha it can easily be used as a day to day rom. extremely fast and very snappy. only thing that i found not working was the camera. (Now on Alpha5)
[ROM][ICS][1-11-12][WIP] ics-deck-evo [alpha5]
All Decks ICS Pre-Alphas
All Decks ICS Gapps
AOSP ICS Kernels:
Jaredthegreat ICS - jared has the most advanced ics rom which is in beta 2 but does not have a working camera to check this rom go here:
[ROM's] -ICS- 4.0.1-4.0.3>[AOSP]<--~B.2.0~
Will post them when they are released!!!
Rom Manager/Kernel Manager:
Rom Manager: This is an app from the android market and is extremely useful for pretty much anything. you can back up your rom, you may go into boot loader and you can check if certain roms such as "CM7 Nightlies" have been updated. However people do prefer Amon Ra for flashing, which is another plus of Rom Manager it allows you to flash alternative recovery, which will flash Amon Ra for you.
Kernel Manager: This app was working before but has stopped now, however if it does start working again what it had was pretty much all the kernels that you needed for any rom. this app would allow you to flash a new kernel immediately by going to the kernel you want to flash.
Reserved
Q&A:
Q: What is SBC?
A: SBC stands for super battery charger. SBC is trickle charging, It stops your battery from dropping from 100% to 90% right when you take it off the charger. Some say that it harms your battery but i haven't seen any harm and plus it only costs $5 to get a new battery on Amazon.
Q: How to set up and flash your roms and kernels?
A: well my friend "Crossrocker" made a guide for this with everything you need. so just click to go to his thread. [GUIDE||Oct/23]Best AOSP(CM7|Decks|MIUI) configuration.
Q: What is the difference between governors?
A: This Thread by "RJackson" explains it all:SetCPU governors (explained)
But if you're too lazy to click it here they are:
As explaind by RJackson:
ondemand - Available in most kernels, and the default governor in most kernels. When the CPU load reaches a certain point (see "up threshold" in Advanced Settings), ondemand will rapidly scale the CPU up to meet demand, then gradually scale the CPU down when it isn't needed. - SetCPU website
conservative - Available in some kernels. It is similar to the ondemand governor, but will scale the CPU up more gradually to better fit demand. Conservative provides a less responsive experience than ondemand, but can save battery. - SetCPU website
performance - Available in most kernels. It will keep the CPU running at the "max" set value at all times. This is a bit more efficient than simply setting "max" and "min" to the same value and using ondemand because the system will not waste resources scanning for the CPU load. This governor is recommended for stable benchmarking. - SetCPU website
powersave - Available in some kernels. It will keep the CPU running at the "min" set value at all times. - SetCPU website
userspace
A method for controlling the CPU speed that isn't currently used by SetCPU. For best results, do not use the userspace governor. - SetCPU website
Interactive - The 'interactive' governor has a different approach. Instead of sampling the cpu
at a specified rate, the governor will scale the cpu frequency up when coming
out of idle. When the cpu comes out of idle, a timer is configured to fire
within 1-2 ticks. If the cpu is 100% busy from exiting idle to when the timer
fires then we assume the cpu is underpowered and ramp to MAX speed.
If the cpu was not 100% busy, then the governor evaluates the cpu load over the
last 'min_sample_rate' (default 50000 uS) to determine the cpu speed to ramp down
to.
As explained by MDJ:
SMARTASS GOVERNOR - is based on the concept of the interactive governor.
I have always agreed that in theory the way interactive works - by taking over the idle loop - is very attractive. I have never managed to tweak it so it would behave decently in real life. Smartass is a complete rewrite of the code plus more. I think its a success. Performance is on par with the "old" minmax and I think smartass is a bit more responsive. Battery life is hard to quantify precisely but it does spend much more time at the lower frequencies.
Smartass will also cap the max frequency when sleeping to 245Mhz (or if your min frequency is higher than 245 - why?! - it will cap it to your min frequency). Lets take for example the 998/245 kernel, it will sleep at 245. No need for sleep profiles any more![/QUOTE]
As explained by teh roxxorz:
Lagfree - like the performance governor. It will scale the cpu to higher frequencies when needed, but not to 100% like performance, so you'll get a lil better battery out of it
SmartassV2 - A smarter smartass governor. Code was re-managed/removed to make it more optimized, and have better scaling performances
InteractiveX - a better interactive governor I believe; low scale cpu settings, for texting, browsing, ect, nothing intensive. I wouldn't use it for emulators, ect.
Q: Do you need PRL/Profile/Radio updates? Do you need to go back to sense based to do these still?
A: No you don't have to go back to sense to do these and you don't have to do these because Rom's will come with what you need. None the less if you would like to update your radios here is a thread by "Calkulin" where he keeps the latest radios updated: [ Radios ][ 9-5 ] All EVO Radio, WiMAX, PRI, NV & HBoot versions
Q: Does HDMI mirroring work on these roms?
A: As of this moment Miui and CM7 both have HDMI mirroring working, and sense all the other ones are cm7 with some tweaks they as well have HDMI working however from what i have read the only one that has not had problems with HDMI is Decks Gingerbread Rom
Q: Are all other major features (4G (except for Miui), bluetooth, front & rear camera, GPS, apps such as Netflix, Skype, Google Voice, Sprint Visual voicemail) all working at least as well as on a Sense or stock ROM?
A: Yes everything is working, however on CM7 and i presume on some others you also have to flash a gps fix which you can get from this thread: [GUIDE||Oct/23]Best AOSP(CM7|Decks|MIUI) configuration. and the Voicemail seems to have some issues for some people but works flawlessly on Decks with it's gapps + Voicemail which you may also get from this thread: [GUIDE||Oct/23]Best AOSP(CM7|Decks|MIUI) configuration.
Q:My wifi is connecting/disconnecting after a second, what should i do?
A: This answer was given to me by "teh roxxorz." This has nothing to do with your rom or kernel, do this:
Back up everything into Titanium Backup
Boot into recovery
wipe cache, Dalvik, and pretty much everything
reflash your rom,kernel and gapps (or if you would like to check out some other roms and kernels just click on the link in my sig)
once you've set up your phone download Titanium Backup from the market
in titanium backup restore all your apps ONLY!!! (don't get apps w/ data - only get apps, and do not get system data)
after this your wifi should be working just fine
Q: I am having wake issues?
A: Here is a Guide made by JBabey[FIX] Wake Issue (Android OS) - Combination of Radio/PRI/NV/Wimax/GPS !Solved!
Q: Can i make my 3g speed faster?
A: Yes, This answer was given to me by teh roxxorz:
You need to flash a sprint sense rom. I emphasize sprint because it won't work on the sense 3.5 roms, as they're all ports of other non sprint roms.
1. Flash sense rom
2. Obtain your msl, download msl reader from market, use it, write it down
3. type in ##3282# , input your msl (you can get this from the app msl reader)
4. Click edit mode > advanced
5. Scroll down to HHTD proxy port and address
6. Change the proxy port to 0 and proxychange the address to 0.0.0.
Q: How can I fix my GPS?
A: This answer was given to me by teh roxxorz:
- flash a sense rom
- open up the dialer
- Type ##GPSCLRX# or ##4772579#
- Your enter your MSL at the prompt
- Your phone will soon reboot > done
Q: Is there a guide like this but for sense roms?
A: Yes if you are looking for a sense guide rather than aosp then check out this thread by tropicalbrit
Q: What is your setup at the moment?
A: Rom - Decks 4.0.3 Pre-Alpha 7 ICS Rom
Kernel - Stock
Governor - Conservative
CPU Max/Min Frequency - 729/128
IncrediControl (app) - (-100) [I get to (-100) by first doing (-75) and leaving it there for 3 days and then I do another (-25)]

Also, you should also disclose to people using Xplod: there's a 50/50 chance the new tiamat kernels [4.0.7+] may not boot, in that case, they should use 3.3.7.
And any reason you were gona message me?

Some features that you don't mention or summarize
that may help me and others.
PRL/Profile/Radio updates? I believe you need to
go back to sense based to do these still? [yuk]
HDMI mirroring?
Are all other major features (4G (except for Miui),

[Q] KTManta vs. Franco vs. Trinity

Hey guys,
I wanted to get everyone's feedback and experiences between the 3 kernels. I realize that every device behaves differently, but was curious about which ones people have tried, if they found any cool things about specific ones they really liked Or if you wanted to share your experience about the latest build.
Thanks!
Trinity and franco are about the same, but trinity>franco.
KTmanta is in a totally different league, it offers total customization and imo is the best kernel just because of that.
Franco and Trinity are all about performance where ktmanta is about battery optimizations and customizations.
I haven't used Franco or trinity in a while, I know they score higher in benchmarks if that means anything at all.
Sent from my SCH-I535 using xda app-developers app
I think everyone knows my preference, but they are all good kernels. Unfortunately this tablet is not on Franco's priority list and does not see much development. I dont believe it has a 4.3 compatible version yet and the last release has a serious bug that causes SoD for most people.
I like Trinity and KManta for different reasons (those stated above). If I need to squeeze out battery life, I go with KManta and tweak the settings accordingly. But for my day-to-day use, I like Trinity for its smoothness. Just my two cents
Awesome input guys! Real useful information.
How would you guys describe KTManta when just using the stock values? When you guys say "customization", do you guys mean the voltage settings and stuff like that? I've been flashing for years, but have never really understood how that worked. Which is funny, because I am an experienced PC overclocker. People say the concept is very similar. If KTManta's customization options were removed, would it be then comparable to Trinity? Or would it still be better without all the options?
Would you guys say Trinity still has decent battery life? Compared to KTManta at stock values?
Which one does Chrome work the best with?
Thanks!
Stock for stock Trinity is better because Morfic hardcodes overclock and undervolt values into the kernel and sets up all that stuff as his stock settings for the kernel. KTManta allows you to do those things and WAY more, but does not set them up as stock values because Ktoonsez prefers to keep the default settings for his kernel closer to the default settings of the stock AOSP kernel. So while Trinity may have -50mv undervolt to everything and a GPU overclock of 620MHz (I think that is the speed?), KTManta allows you to go +/- 200 mv to any frequency step for CPU or GPU that you feel like and also allows OC to 2.1GHz on CPU and 720MHz on the GPU if you want to, as well as RAM OC if you want to, and control of the scaling of every part of the chipset, again if you *want* to. But it doesnt set any custom stuff as default since everyone's device is unique and people want to do different things with it. That is why we have pre-made settings available from various users so that you can load custom values to try out without having to go through a bunch of experimentation yourself.

[Q] best kernel for performance for Cloudyflex 2.6

Hi,
Is the cloudy kernel the best for pure performance in terms of lag? Not looking for battery or other performance enhancements.
Is cloudy kernel 1.5 the latest ( just to make sure i have a backup kernel to re-install just on case)?
Is the tweak on hidden menu for HIGH TEMPERATURE still relevant with these kernels?
I am running with ondemand governor.
And just to make sure:
- to install a new kernel i just boot to recovery and flash the kernel without any wipes, right?
- i have xposed and some G2 tweaks running, i don't need to disable/reset or anything?
Thanks for your help! I am still learning.
Nico.

Hello Nico.
I'm hoping that I can assist you with this topic.
First off, regarding the kernel you have plenty of choices. There are two, however, that I'd recommend.
1. Dorimanx Kernel. That kernel is absolutely amazing with LOTS of tweaks, thermal protection, ad-blocker, allows overclocking to 2.8Ghz and much much more. I can't list all the features because they are so many. But there's one thing in particular - it's fast. Dorimanx has created a hybrid kernel from 3.4.xxx and 3.10.y source codes. This is my go-to kernel.
2. Bruce Kernel. It's a modified stock kernel with Bruce's own tweaks. It's fast, very battery friendly but lacks customisation. It also doesn't have thermal protection or any thermal throttling.
Now to your other questions:
Yes, Cloudy 1.5 should be the latest.
I wouldn't mess with the ROM thermal protection found in hidden menu. The gain in speed is most likely negligible but you make your phone more prone to heat damage.
Ondemand governor is great for smoothness, but you'll have a ton of options if you decide to use dorimanx. I use alucard because it's the sweet spot between amazing battery performance and smoothness.
You can install a new kernel without any wipes. Kernel doesn't interfere with ROM as such and you don't have to disable anything. A Kernel is basically what makes software and hardware work together.
I hope this helps!

Thanks a lot for your answers, these are exactly what I was looking for.
I just flashed Dorimanx, and without knowing too much on how to tweak it (more on that later), it is really smooth. I am keeping it!

Thanks. Flashed perfectly, twice (I had trickster mod on and wasn't sure what it reset at boot, so uninstalled it and re-installed Dorimanx.)
Got 1040/2900 on geekbench even if that is not really what I care about. I had 950/2750 before, not that much noticeable difference in %.

Ondemand governor is great for smoothness, but you'll have a ton of options if you decide to use dorimanx. I use alucard because it's the sweet spot between amazing battery performance and smoothness.

OK, we're onto kernel tweaks , I have a few questions:
I discovered that I had STweaks installed, so let's use that.
1) Apart from governor alucard, what other settings should I apply? You mention thermal controls. I expect the defaults of STweaks are OK? If not, what should I do?
2) I found a GPU governor, should I do something there to have better performance?
3) my real goal is to achieve super smoothness when interacting with the phone, I don't play high CPU 3D games or anything like that. I want the phone to react instantly when I press somewhere or open something or press home or recent apps. Any advice? I modified touch boost frequency...
4) if I "reset settings to default" in STweaks, will it reset to Dorimanx' installed default as I just installed the kernel?
5) so that I don't bother anyone anymore, is there a manual about all these tweaks in Dorimanx/STweaks?
Thanks again so much!
Hey bud, I dont know if u found out the answers to these questions but I can share my information with u as I see nobody answered it
1)
2)
3) I'll tell u the best settings for smoothness but also with great battery life All questions ll be answered in one answer :
Make governers Alucard
Touchboost:1.9
Powesave Switch: Performance mode
Power Efficent Worqueues : Unticked
Cpu Tweaks:ticked
Max Cpu 0,1,2,3 freq:2572800
MAx screen off freq :Max Allowed

And from developer settings of ur ROM, make window animation, transition animation and animation duration scale 0.5x
If u re not dependant on xposed module, then use ARTruntime(faster)
4) Yes, all settings ll be restored to original Dorimanx settings.
5) I havent seen any yet
This is all I can say, let me know about results

Hey there. Thanks a lot for your answers, despite the thread being so old.
I actually learned a lot since i posted that
I use 2x intelliactive, 2x alucard, alicard HP, max freq 2.3, 2.3, 1.9, 1.9, gpu 100-533, i/0 read 1024, dirty tatios 5%/10%
Your settings look interesting, you sure you get great battery life? With 2 cores min? I am going to try
No mate, I said that's settings for u, u said u don't care about battery, so I tried to give u the best settings I can come up with for performance, I myself use 3 cores max, all 2,3 ghz 1 core boost, Alucard on-demand Alucard. 1024. 100 320 GPU. It's pretty smooth with art. But if I wouldn't care about battery, I would do the settings I told u. Hehe

no worries!
I learned to care more about battery I realized that it is really smooth anyway. I have a lot of SOT daily (movies, etc) and realized that using performance settings just drains too quickly and is not needed.
I do put animations to x0.5 (transition animation to OFF).
What I am really struggling with is home redraws... A bit better now, but they used to be 1000x times a day.
I would run with ART but it takes a lot more memory, and with my 16 GB I don't have enough memory left when running ART.
Buddy, I am on 16 too. I had 8.5 hours sot with art and cloudy 2.1!! I use nova launcher and I am happier with it can give it a try

I have a few very large apps (navigon, games,...) they take 2-3 GB.
I al so have movies, remaining is only 1.3 GB.
If i want to backup ROM i need to delete obb files, etc. With ART i will have nothing left!
Tried niva but didn't like it. Will try apex again maybe, but i really like the look of G3 home.
Hmm, I see. I didnt know that internal memory and has a thing to do ART, I just made it ART and everything was ok. Launcher is a matter of taste I guess. For lg launcher, I read that there are some hidden settings to lock it in RAM, so that it doesnt redraw that often, maybe u can take a look for that. Hope to share more information for better experience with our phones
@bloof I forgot to tell, I also like how g3 theme looks, and I use a g3 theme with my nova launcher. If pm me ur gmail, can send u my screenshots

Kernel questions.

Hello XDA members,
I have looked around on the internet and XDA and I couldn't find a satisfactory answer to my question so here I am.
1. What is the function of Kernel?
2. What is the advantage of custom kernel over stock?
3. Is Kernel something that I just install and forget? or do I have to make edits. If edits then what sorts?
I am using latest TWRP, Pixel Exp with magisk. About to try the xposed beta. Thought get more in depth to get max out of my device.
Thank you all in advance.
1. A kernel is the "core" of the OS, a piece of code that acts as a mediator between the hardware and software in your phone. It decides how your apps can use the hardware, it manages your CPU's and GPU's clock speeds (lowering them in low usage and raising for resource - intensive apps) and manages the voltages your components operate on. It also reserves RAM space for apps, decides on which CPU cores an app will run, etc. Everything you do, all input sensors, everything your apps do, and all your phone's output information goes through the kernel.
2. Custom kernels are customised kernels, tweaked to the liking of whoever created them. The benefit of custom kernels is that they are usually better optimised, they handle and distribute your phone's resources better than the stock kernel, which can give you better battery life and performance. It can also be changed to allow overclocking, meaning higher CPU or GPU clock speeds. Paranoid Android roms use a kernel that is extremely well-optimised for Qualcomm's chipsets, probably the best kernel for our device.
3. As for edits, some kernels are made to be better optimised for your device, providing a performance/battery life improvements out-of-the-box. Most kernels come with an app, giving the user control over how their kernel behaves by allowing manual tweaks, where you can raise/lower CPU and GPU clock speeds yourself. They also add some functions, things you couldn't change on a stock kernel, and some add extra CPU governors to choose from. Governors are behaviour models for your phone's CPU, they define how your CPU acts, how fast it raises clock speed under load, and how fast it lowers it back when high processing power is no longer needed. For example "performance" governor will always keep all cores at a maximum clock speed (which draws loads of energy), while "powersave" will reduce clock speeds to a minimum. Custom kernels usually add custom made governors that aim for performance, battery life, or balance of the two.
There are many more tweaks to the kernel, like memory-management, which tells the kernel when to kill bacground apps, and how many apps can remain open in background (in RAM) before getting killed.
As for if you need to change stuff in the kernel, most of the time they come preset to the values the kernel creator thinks is best, so probably no, but you sure can benefit from researching the tweaks and creating custom profiles if you need to squeeze maximum battery life from your phone when your battery is almost dead, or you want to play some intensive games and need every bit of power your phone can give you.
In my opinion, Moto G5 plus has a pretty decently tweaked kernel, but since it heats up very little and has great battery life it has some overclocking potential. It should probably be able to handle a boost to 2.2GHz like on Snapdragon 626, which seems exactly the same as 625 just with a higher clock speed.

Wow.
Thanks for such a detailed reply.
I will download alize and see where it takes me
Thanks again.
