Kernals

Sorry guys if this is a bumped thread.. Couldn't find one that helped me at all.
Alright, I would like to know, What is a kernal. Ive flashed almost every rom possible but i havn't done anything with kernals.
Thanks

I've heard it stated as "a bridge between hardware and software." They control your processor speed for certain circumstances (screen off) and what voltage your processor gets at certain speeds. It can also come with different things like audio boost and enhanced multitouch capabilities (3+ finger input). Just remember to flash a sense kernel if you're on a sense or senseless ROM, or an aosp kernel for an aosp ROM. I always wipe dalvik cache and cache partition before installing a kernel, just to make sure theres going to be no problems.

So what your saying is , different kernals do different things twords performance ? And what is cm 7 rc2?

Correct, there are some overclocked kernels and some that are stock speeds, plus all of the different tweaks that can be applied. And CM7 RC2 is a ROM. CyanogenMod (ROM name) 7 (version) RC2 (release candidate). Its a pretty popular ROM.

Lmao no man, im running cm7, love it to death. What is CM7, aosp ? I know its senseless.

So not to jack your thread but its highly related to the question I've been asking today. I understand the description of a kernel above but then what would be the main differences between the kernel and the Rom of a device? Are kernels simply used to modify aspects of the phone such as processor speeds or do they also have something to do with the UI?
Sent from my ADR6300 using XDA App

I dont think they have any effect on the UI

So besides just processor speed,what else could a different kernel affect?
Sent from my ADR6300 using XDA App

CM7 is AOSP.
Kernels don't affect the UI, they control processor speed mainly, but they can also come with patches that boost audio levels and enable fast charging or trickle-charge (SBC [when you charge your phone normally, it gets to 100% then stops charging regardless of being plugged in and runs off of the battery power til about 90% ish resulting in the infamous dropping 10% battery in like 5 minutes scenario. This mod enables the phone to drop its charging current once it hits 100% instead of turning off completely, maintaining the battery at 100%.]). Pretty nifty stuff

I'm not exactly sure about the BEST, cause different things happen to people when using the same kernel, but I've been using chads incredikernel from 3/18/11. No problems with it so far.
Sent from my Droid Incredible running CM7 RC2.

I heard that kernel had smartsss governor ? What's that do .
Sent from my ADR6300 using XDA Premium App

Yep, it does. I'm not too familiar with what it does, but I've heard it basically favors lower CPU speeds, saving you some extra battery life. I've yet to notice any lag or slowness from running that governor. I get pretty good battery life with this kernel too, so I figured I'd stick with it.

Would calling a phone a car chassis, a ROM the motor and a kernal the driver be a good analogy?

Kernel/Sense ROM question.

Hey guys, sorry if this has been asked before, I usually don't hang around the Evo 4G forums since I have a 3D. However, my wife has and Evo 4G and uses it quite a bit. Is there a kernel and or Sense ROM out that significantly increases battery life over stock? It doesn't need overclock or anything. Just stable with better battery life.
Thanks in advance!

There are many different roms and great kernels that fits great for some. I use (an example) EVOlvedroms. With that I use either more freedom kernel or chopsuey 9. Both work great for me and had excellent battery life plus stability. Check those out. Hope that helps.

How do you have yours set up? I have CM7 with Savaged Zen and it runs faster than any other ROM/kernel combo I've tried.

Im not running setcpu so its not overclocked or underclocked

Good luck with that kind of find...
If you're looking for a sense-like feel, why not just go with a sense ROM? I personally use Synergy ROM and everything works super fast, no issues, and service seems to be better than when I had CM7 on it. That and sense ROMs also make full use of the phone's hardware, such as the camera...
The support and extras are a pretty sweet deal, as well.

Signal strength is not universal. You can have the same signal strength on your phone but it will display as a different number of bars based purely on your ROM. CM seems to be one of those ROMs where I have a really good signal yet I'm only showing about 2 or 3 bars. Its just the way the ROM displays it. Flashing another ROM and getting more bars doesnt mean your signal strength is any stronger or weaker at all.
Also, if you're looking for a sense feel then just get a sense ROM. There are a lot out there to choose from. I'm actually thinking of running Boot Manager on my phone and flashing a sense ROM alongside CM7 so that I can make use of the abilities of the sense ROMs when I need to.

I switch between Fresh 4.22 and CM7 pretty regularly and love battery life/performance of both. I use Tiamats 4.1 SBC on CM7 and the stock kernel on Fresh, although it would be choice if there were a Sense SBC kernel.

Any chance u got the link for that frsh 4.22?
Sent from my PC36100 using xda premium

I keep coming back to Mik's roms. On MikG now and love it. Battery life is great too but then I use all the app tricks I can find. App2SD / DroidWall / SetCPU / StartUp Auditor. If your signal strength is bad just call Sprint and ask for an Airvanna. Once it's hooked up you should be up to 4/5 bars constantly. That's been my experience.

Have you tried team nocturnals merge Rom its sense based with an soap feel its pretty nice if you are trying to have your cake and eat it too

Why is finding a decent Rom for the Evo4G with 4G so darn hard!!!!!
What makes the Evo/Android OS so hard to incorporate into Roms?
If their are any 2.3.5 + 4.67 +4 G Roms that are worth trying let me know!!!!!!!!!!

This behavior happens due to the way in which batteries are charged. It happens on many ROMs and kernels for the 1st 10%. What is important is what happens after that. If you want to avoid it entirely the only sure-fire is to use an SBC kernel.

That makes you completely ignorant for making that statement. Yes it is harmful in the long run, and they don't include it because of that and the things that can happen to that battery that cam cause the user harm.

try swagstr SOS X, it is my daily driver and doesn't eat the battery up on mine.. You may also want to download a battery calibrator after flashing a new rom

Read up on and try each one and see what other people are saying till you find the one that your phone likes

I agree with penny. You have to try them out yourself.
I'd recommend sticking with the default MikG 3.1 kernel (which is the latest HTC kernel) for a couple weeks so you get used to it. Then jump to lionfish and see if you notice a difference in battery life and responsiveness. Personally I don't notice a difference in those areas, but others have been wowed by the latest HTC kernel. Some people say it takes a couple days for a ROM / kernel combo to "settle in." Your phone will have to rebuild the cache and dalvik, and it does that over time as you do different things on your phone.
Lionfish is not based on the latest HTC kernel since they haven't released the open source yet, but it has other features of course, like HDMI mirroring.

Thanks guy ill check them out
