NOOB ALERT!!! What are kernels?

What are kernels and how can they enhance my EVO? My evo is rooted and I'm running Myn's Warm Twopointwo. Bash me if you have to just throw in some answers too ^_^

Kernels control the CPU/gpu
They allow you to overclock or underclock.

It's the central-most part of your phone that controls communication between software and hardware. if anything happens on your phone, the kernel is involved.
the reason this is beneficial to you is you can tweak it to suite your needs. For instance, over in the dev section, they have kernels for balls-to-the-wall speed and power, or kernels for better battery life with slightly less performance and of course, middle-of the road all-around good kernels.
Just keep in mind, as you're flashing and experimenting with kernels, go SLOWLY. if you screw this up, you'll be very unhappy. I've been told that doing a full nandroid backup will backup the kernel as well and save you heartache if you screw something up.
good luck!

Rofl!! This made my day!

Simply put, kernels are drivers, much like your PC's video card, audio, keyboard drivers. It's the coding that translates software commands into hardware actions.

Lol @ KFC reference. So what will replacing them do for performance?

Kernel talk should be directed to the Pop Secret thread. Mods?

Kernels, well, it seems you kinda got your question answered, but ultimately they control the phone. How much battery is consumed, how fast the CPU is running, etc. And that guide that was posted was actually what I was going to link you to. It's some great information.

From my understanding kernels are very tasty with butter.

Just add butter & salt.
As stated, it's a layer of software between the rom (OS) and hardware. Some kernels are tastier than others.

Made the jump

Well guys it has been fun I made the jump tongue 3vo and have to say it is an amazing device. I have been sceptical about everything worrying if the 3d was a gimmick or worth it. I compared both phones side by side and the colors were way better and looked sharper. You could tell it had some power under the hood as the phone easily handled everything i threw at it . I have enjoyed flashing custom roms and look toward doing the same as you all know one flash and your hooked. Today I will test its legs fully with the battery and gaming. See you on the other side.

It's in my nature. Starting a thread in the EVO 4G General Forums to announce that you got the EVO 3D is a cool story, that is why I posted it.

OP is douche for this thread

You fail at fail, it's meant not ment, what's your excuse? Also, he was using his phone which tends to auto correct horribly at times.

Feed the trolls people.. I thought about going to the new evo, but I think there will be something better this christmas my sources say.

Awesome looking forward to flashing tonight just waiting to see qbkings review video

It actually is working very well. Includes a new CWM 5.5.something...lol.
Messaging app sucks...no dark option.

I so want to flash this, but I need my phone to work and the bug list is long and distinguished.
I can only imagine the progress they can make in a few weeks, then when all you die hards get all the problems worked out, then I pounce!

Face unlock is working pretty well. Got to be in a well-lit room though. But from m experience, it's working. It might not recognize your face sometimes. Try it for yourself. qbking77 also had a video on YouTube showing the face unlock feature on the Epic 4G.
http://www.youtube.com/watch?v=iM4upoE1CtQ&feature=mfu_in_order&list=UL

I flashed it and face unlock is there. cant comment on how well it works because im in a darker room but i love it. I dont really want to go back to CM7. ahh why do i have to choose. :-(

Update: I've noticed it gets used to the charger and the heat goes away once the battery is at a higher percentage

Same experience. I was playing around while it was charging and it was hot. Checked the battery temp it was 102.5 or something. Put it down for about a half hour and checked the temp again and it was right around 90. And the battery was about 80%.

Why did the thread get temporarily closed?
Edit: Nvm, I worry too much.

Over 1000 hr uptime on JB

This is my nexus s up time record. 1000 hr (over 1 month). increíble :laugh:

Nice. some more info about rom, kernel and usage would be nice. Thanks!

Yes some info about ROM and other stuffs , though am pretty sure I will end up formatting and trying a new ROM in a month but with my ZTE Blade I found my stable ROM a long time back so this kind of uptime was normal in that still not so on Nexus.

i use stock rom and kernel on 2g and auto brigteness. (screen shot update on first post)

GG man GG! I havent seen this since some awesome bloke did it with oxygen 2.3.2

Stock rom's are actually stable. I'm sorry to tell you guys, but that's nothing impressive. Two of my coworkers have their running since they got updated to JB, and they're i9020a. Admittedly they are used as work phones but the point still stands. What is impressive is finding a custom ROM or a ROM with tweaks that can do this.

Many times custom roms are unstable, but there also stable roms..
Perhaps people who uses custom roms, like to flash and try new roms, change kernels and so on. So it's obvious that uptimes are lower than a user that doesn't change anything for 41 days (1000 hours)...

What's your RealPi score?

Anyone done a Pi bench on their S6? I imagine several others Pi scores will beat my 6. 30 seconds.
Use AGM + FFT Formula, test 1000000 digits, and post your fastest time.

Bah! I'll have to run mine again, see if it'll improve.
Nice score!

Aha! Power off device and cool down seemed to help (maybe?)

Sorry guys
First run after download, no special settings, only power saving mode is disabled.

Nice one kurczak94! However...
I just did another run. I believe this is going to be the fastest that the test will do on my phone.
edit: oh, nope, I'm wrong! I just did another faster test which I'll post in a bit. How are you guys getting the full length of the result screen showing in your screenshots? I have to scroll down to show the time and that cuts off the top saying 'Intitialising... '

Wow, nice! I can't beat it ;(

One more. I wonder if THIS is my limit. Who's going to be the first to 1. 18 I wonder. :fingers-crossed:

You probably will, I'm getting nothing faster than 6. 19 at the moment. Good score, you've matched me.

Not sure if this is considered cheating, but I'm running the Sac23 ROM and Ktoonsez kernel on my Sprint S6. I didn't expect to get a higher score cause I haven't adjusted kernel at all. I might try some over clocking and run it again later.

Let's see what others say about it, but imo, it's legit because you've simply managed to get the phone tweaked to run faster. Excellent time! :good:
Pro tip for everyone: Power off the phone and let it cool right down before running the bench to obtain the best scores. Example, when I ran Pi just a moment ago after just finishing running antutu, my Pi was over 8 seconds.

After many attempts yesterday and today of running the test consecutively, I just this moment got a freak 6. 17 seconds.
Edit: skip that, just improved again. 6. 16 secs. Blimey.

First go 5.61 got 5.57 second try
