Can anyone explain to me what kernels are what is their function? I noticed that the update did not change my kernel. Is that a bad thing that they did not include a new one in the update? Also I am voinv to be installing xboarxers stock. Rom first to root the phone and I want know if I should chance the kernal and what effect it will have. I am taking small steps because want to understand what I am doing. Thank for any help you guys can give me.

The kernel is the lowest point in the system. It controls how the software communicates with the hardware: how the CPU behaves, how the buttons behave, how the screen functions, etc.
The main use of custom kernels is to Overclock and Undervolt. OC means pushing your CPU to be faster than it was ever intended to be; you get better performance but if overclocked too long, it will be damaged. Worst case scenario, you will literally melt your motherboard. But this is only a danger if you leave it overclocked 24/7 and constantly push the CPU to its limits (playing 3d games for instance)
Faux's kernel can OC to 1.5 GHz and Morfic's can OC to 1.1.
The next common use is Undervolting, which means giving your CPU less electricity than it would like. This again is extremely dangerous if not done properly, but yields noticeably better battery life. Morfic's is the best for UV IMO, though you cannot change the undervolting, he has it locked into what he has found to be the best. And this isn't necessarily a bad thing, as too much UVing will cause potentially serious stability issues with the device. It's not nearly as dangerous as improper OCing (it won't permanently ruin the hardware) but it is a danger. Faux's lets you UV to your heart's content.
Faux's is better if you want performance, because it has higher OC. Morfic's is better if you want battery life, because it has better UV and the CPU clock speeds themselves are better tuned for lower speeds than higher ones.
I absolutely love my faux kernel. its at 1.4 and amazing battery life. The screen sensitivity is awesome. Honestly its all prefrence.... I won't go away from cm7w/ faux

Can you flash faux kernel on top of bionix 2
Sent from my HTC Sensation Z710e using XDA App
When you flash a kernel, you just need to know what the base of it is to pick the proper one. There are really only 3 bases at the moment:
1. Stock 2.2 That'd be faux's .5, and I know morfic has some older 2.2 based kernels in his thread.
2. Stock 2.3 (Which faux is working on now, there are a couple floating around)
3. CM7 Faux and morfic both have kernels that work here. (2.3.4 and 2.3.5 based roms use this, miui, and of course cm7 )
Bionix is based on 2.2 (Which I haven't actually checked, but I'm sure it's in the first post.)
For most of them, just read the first post, or even the title. It'll say what it's based on, and then you can flash whatever you want. Just always do a nandroid backup before, you never know if you might for whatever reason have to flash back. If you don't, you need to reinstall your rom (or manually change the kernel and modules, of course) to get back to what the rom came with.
Happy flashing.
If i am running stock rooted GB OTA, can I flash faux's latest Kernel 006 with ext4?? Or do you have to have an ext4 rom to be able to flash ext4 kernels?
Thanks.
Thanks a lot that shed some light on. The subject
So it appears that the dev will tell you which mernels arw compatible with their rom in the thread for that particilar rom. If I want to use eglesblood which is 2.3.4 or.5 xan I use tbe stock kernel? Also what is the difference between the .3 .4 and .5 in the gingerbread make is that carrier specific or moel specific like the blackbwrry 8520 is for tmo and 8530 is for sprint?
Sent from my LG-P999 using XDA App
2.3.4 and 2.3.5 are based on cm7 code, so you'd use the cm7 based kernel. (LG hasn't given us 2.3.4 or 2.3.5).
As far as ext4, it's a different file system is all. Faux's kernels mount the data and system partitions as ext4, but don't actually convert them. Morfic's do a full convert. Ext3/4 support is in the kernel, not the rom, so as long as the kernel supports it you can do it. (Which every custom kernel I've seen supports ext4)
If you want more information, google is your friend. Here is a pretty simplistic explanation of the ext2,3,and 4.
http://www.thegeekstuff.com/2011/05/ext2-ext3-ext4/
As for the differences, 2.3.3 to 2.3.4 had some major framework changes. 2.3.4 to 2.3.5 seems to be only minor bugfixes. If you want full changelogs, I'd google them.
So if I want to use eglesblood then I have to change the kernel too? Do I have to do it separately or is it included in the rom?
Sent from my LG-P999 using XDA App
You never *need* to change kernels. Using the kernel that comes with the roms works just fine. Only time you need to change kernels is if you want to overclock, (never really saw the point in it, and quadrant benchmarks are useless.) want tun or cifs support, undervolting, ext4, etc.
If you don't need any of those things, or don't know what they are, just stick with the kernel that comes with the rom.
Okay that's cool so all I have to do is put EB on my SD card and flash away I am thinking about starting simple first with either xboarders stock or tweeked

hey guys.. i guess im kinda new with androids but all i have is a question... now the i learned how to flash a rom.. its very cool but why do we need kernels what does it mean? just flashing a rom thats not all there are kernels and other stuff but i dont know what they are and what for
Kernels are the core system. Sort of like drivers. Custom Kernels affect stuff like Overclocking for speed, Undervolting the processor to save battery, GPS locks, WiFi range, etc.
They can increase stability, speed, and battery.
The big thing, I think, that most people sought after is the Overclocking/Undervolting (OC/UV). This overclocks the processor while lowering the power usage of the chip at the same time. So you get a faster phone while saving battery. Brilliant. It is my understanding that custom kernels come with normal settings by default. They only ALLOW overclocking abilities using programs like SetCPU and the likes. I think the voltage is lowered on all speeds though, so flashing an UV rom will save you battery even if running 1ghz stock speed. I've seen people go up to 1.4ghz.
It is best to test a rom first for a few days. Figure out what bugs you encounter, if any. Get a feel for the rom so when you flash a new kernel you can see if it will work for you. If you do too much at once and you encounter bugs it will be hard to pinpoint.
I've flashed custom kernels but don't do it often. I know CM roms have their own custom kernels that I believe are flashed back when flashing the rom. This is why CM7 differs from stock in a lot of ways. One example is stock G2x won't work with Wii remotes. The bluetooth stack in the kernel is a custom LG one and doesn't work. CM uses a more common bluetooth stack so you not only gain this functionality but also others.
The list goes on and on. I think most of the custom kernels are BASED off CM7 and are only compatible with CM7. I think a custom kernel on top of a stock LG rom will cause bootloops. So the kernel and rom have to work together.
I am not an expert but I think I've touched the bases. Someone correct me if anything is untrue or misinformative. Technicalities aside, this is the gist of it.

Yes, I FINALLY did it!!! I overclocked my G2X. I would appreciate if anyone could share their experiences with o.c. pros and cons... Should I retreat or stay where I am? Please some feed back!
Over 1300 seems to cause trouble on mine.
i dont think oc'ing is really that necessary with a phone this fast but if u must i wouldn't go above 1.3 (just seems unstable above that). I think the "Pros" come from being able to underclock. Setting up profiles for uc'ing when screen is off or as battery level drops etc really prolongs the life of the battery (at least in my case)
On my OG droid that came limited at 550 mhz, ya, oc'ing was def necessary but I cant really think of any "Pros" for oc'ing this phone.
each phone is different though so play around and you'll find a combination that works great for your phone, good luck
Well... you can get some serious bench scores... This thing rocks the Mandelbrot multithread test in smartbench 2011 at 1.5 ghz. Other than that it helps with games.

What about the CPU not having enough cooling and frying the CPU over time. I presume its just like Desktop overclocking but without all the extra cooling you can add to make it safe for the hardware.

But what i really want to know is if oc could damage the phone. After all if there is that danger it's noy worth it...
In all honesty I used to be really into benchmark scores and OCing the heck out of my phone and under volting it in the process but that led to many battery pulls ect. What I've noticed is just keep it at stock and mild uving seems to be the best for me its stable decently fast just 2 cents though
Overclocking a cpu is the same as on a pc, only a bit more dangerous on a phone. (This phone already has overheating problems running at stock speeds ) On a computer, people pay a premium for parts that are easily overclocked, and have either very good fans/heatsinks or a liquid cooling rig.
Overclocking is dangerous, especially because not all chips are going to be made equal, even if they come off the same production line. These chips are designed to run at a certain voltage, and certain clock speed. As far as real world use, (NOT benchmarks. Sure, they look pretty and all, but benchmarks are never very accurate.)
Sure, you might get 2-3 more fps on your games, but is that worth the risk of shortening the life of your chip/phone?
(And just so you know, I've been building/overclocking pc's for years, but I also understand what you need to do to keep it stable, and it's *all about cooling*.)
If you're not convinced, try this. Don't overclock your phone, and use it for a few days. Tell me honestly that you really notice a real-usable difference with the chip overclocked or not. (Games set aside, but like I said, getting a couple extra fps on a game to me isn't worth the risk without a proper cooling setup)
For those of you that really don't understand what you're doing to your chips when you overclock, I'd suggest doing some reading about it. A good place to start would be here: http://en.wikipedia.org/wiki/Overclocking
So you think using fauxs kernel is not safe or reduces the life of the chip? I just flashed it and didnt oc or uv further then fauxs default settings...

I'm not saying it's for sure, I'm saying there's a chance.
Plus keep in mind that these kernels have other really nice additions besides overclocking and undervolting. I'm using faux's stock voltage kernel ext4, and leaving it at stock settings, and it really works great.
I just posted this up because I see a lot of people more interested in quadrant scores (which to me are pretty useless) than stability of their phones. If you do overclock, and it works for you, more power to you. I just want to inform people. I'd HIGHLY suggest if you aren't sure, read that wiki article, it's a great place to start. (not all information is there, but it gives a very good general idea on how and what overclocking is.)
Thanks! i always like reading knowledgeable and informative posts!

OK, you definitely convinced me.... I have also faux (let me tell you exactly - Kernel Version 2.6.32.9 FR Faux 123-v0.03) on EagleBlood 1.05. Could you please tell me what I need to do set up in order to be safe? Thanks!
I'd just go to faux's thread in the development section (his froyo thread, not the cm7 one, since you're using eagleblood), and download his stock voltage kernel. (It's in the first post.) He's on .04 now, by the way.
Then reboot into recovery, and flash the file you downloaded. It'll overwrite your current kernel and modules with the new one, then reboot.

And a lot of times the kernel will be credited to the developer. So if you see "faux's kernel" people are referring to kernels by faux123. Trinity kernels were developed by morfic. If you are having a hard time finding a specific one, look at the top left to see who started the thread and sometimes that will help find it. Does that make sense?

Can anyone tell me the benefits of using a kernel like Trinity or netarchy or matr1x?
I've been searching and basically I want the stability of the stock kernel, but with better battery life. I was eyeing the trinity undervolted kernel but wasn't sure if it would affect anything in terms of FC or performance?
Oh, I'm using MIUI and was reading around and some people have experienced different negative things when using this ROM?
Well other kernels have a lot of features, like oc'ing, uv'ing, bln, voodoo, etc haha
Ohh okay. The only thing I see of benefit for me right now is the undervolting to increase battery life. I mean I haven't met an app that I can't run yet so no point in over clocking.

Sent from my Google Nexus S using XDA App
I'm kinda new to all this, but what is the difference between changing a kernel versus changing a ROM? or is that the same thing?
for example, i understand backlight notification works on some kernels on the nexus s...does this require changing the ROM? any help would be appreciated
A ROM is basically the custom image (think of it as an os) for your android phone. ROMS are usually based off of stock android or cm7. ROMS allow for differen gui's, etc.
The kernel is basically the piece of software that allows the rom (os) to communicate with the hardware of the phone. You always see things in kernels called "voltages" or cpu speeds...that is set in the kernel, and allows the phone to run at a different cpu speed. Also, you see bln. That communicates with the hardware and allows the back lights to light up when you receive a notification.
That was a simple explanation, but it gets the point across
thank you for that...makes perfect sense... so if I want to just get BLN working, is there a kernel that would work with my stock ROM? or do I have to use the kernel with a specific ROM? I'm still unsure of the steps required to make this happen
Bln is baked into a kernel. Just flash a kernel and u will get bln

I recently rooted my P999/G2x and installed CM7.1.0.1, and am extremely happy with it. Am looking to tinker just a *little* bit more, but have some questions... I have LOTS of answers on the forums, but am somewhat skeptical about the currency of some of the information out there (let's face it, stuff changes fast!). So, down to it:
Kernels:
- Did CM7 overwrite the stock kernel?
- I understand the benefits to changing the kernel; what about drawbacks?
- Does CWM back up your kernel with Backup and Restore? If not, how do you do this?
- Recommendations on a good, reliable kernel to use w/ CM7? I am looking at faux123's CM and morific's Trinity. Thoughts?
OC/UV:
- Can you OC on stock/CM7 kernel?
- What is the best app to manage OC/UV? I have my eye on setCPU, cpu Master, and Android Overclock (JRummy16)
- Any recommended settings for the G2x? Any settings to avoid? My plan is to incrementally adjust, but don't really have an idea as to where to start.
Thx in advance!
- Did CM7 overwrite the stock kernel?
Yes
- I understand the benefits to changing the kernel; what about drawbacks?
Since not all the chips are made in the same way, you could soft brick your phone if you try to flash an undervolted kernel. This is the way mine is, and it's somewhat irritating but not all that bad using the stock voltage and overclocking to around 1.4ghz rather than 1.5ghz+. Also, battery life should be expected to be less with an overclocked CPU. It's up to you to decide how you want to run your device.
- Does CWM back up your kernel with Backup and Restore? If not, how do you do this?
Yes, backup creates an image of the entire thing. Before you start making changes, always make a backup so you can revert to previous settings should you soft brick your device. Make a backup, clear cache/dalvik, flash the kernel and reboot the phone. First boot times will always be a little longer when flashing a kernel, so be patient and don't pull your battery right away. For me personally, if it hasn't done anything noticeable after about ten minutes, I pull my battery. Reboot into recovery and restore from the backup you made. If you started off trying an undervolted kernel, time to try the standard voltage now!
- Can you OC on stock/CM7 kernel?
No, and you'll be able to tell once you flash CM7 and use SetCPU (or whatever you use) and see the max is still at 1ghz.
- What is the best app to manage OC/UV? I have my eye on setCPU, cpu Master, and Android Overclock (JRummy16)
Personal preference. I think probably SetCPU is used by most people including myself.
- Any recommended settings for the G2x? Any settings to avoid? My plan is to incrementally adjust, but don't really have an idea as to where to start.
If you want to be safe just start out at 1ghz. If you have no random reboots with your kernel then move it up to 1.1 or 1.2 and see if it's stable there. Personally, I just went ahead and overclocked to 1.4ghz. For the most part people don't really have problems with this I guess. The problems usually lie in whether or not you are undervolted and by how much. If you find your device can run an undervolted kernel, I would just leave the undervolt settings the way they are. As I said, I can't run OC/UV and have to use SV, so I never touch any of the voltage settings.
Hope this helps!
Using eagle blood (cm7 based) with faux kernel.
I heard trinity kernels may have random reboot but don't quote me on that.
Try faux kernel with oc/uv. Its very good, latest is 0.48. But if you go with the ds version (debaouch?) The battery percentages are all over the place... Lol one minute its 50% the next it may be 34%...
Use set cpu. I've uv additional 25mv across the board with no I'll effects. Screen off profile at 503 mhz max and some other profiles will have you getting 24hours easily with normal usage.
Make sure test it out before you "set on boot"...

+1 to everything you said
just to add if you want to over clock then go with faux or trinity. the cm7 kernel is faster then both @1000mhz, if speed is what your looking for without the dangers of oc. The stock cm7 kernel also lacks the ability to under volt soo battery life might not be as good though

I honestly do not have the time to read hundreds of pages of forums to see if someone has allready had this issue.
Of course i tried searches.
It happens on any cm9 nightly, not just the latest one.
I want to be back at 1.2ghz. being stuck at 1ghz. is rediculous to me after being so spoiled. (lots of google earth, gaming and other stuff that a higher clock speed helps with)
If I have to I will just go back to 2.3.7 and a swift 1.3ghz. MAX
BUT it seems like I should be able to overclock using CM9 on my captivate.
Please do not explain the system settings and performance yadda yadda yadda, anymore, i am obviously familiar enough with an android device to know how to use system settings etc. if i can root and install custom roms i can read and point and click as well.

Were you using Glitch before, or some other custom kernel? I didn't think cyanogen's stock kernel supported overclock. If you install a new nightly you have to reinstall your overclocking kernel.
I have been using cyanogenmod only. I never purposefully installed a custom kernel then the rom. Just used Odin to root/clockwork and so forth. Never heard of Glitch. Through out all of my custom rom experiences with the captivate I have been able to use the sys. settings or osmonitor to overclock to a max of 1.3ghz. I have tried miui or whatever its called for about five minutes. other than that just cm6/7, then updated to cm9. in the past whatever kernel i had, stayed in effect, i guess.
I will do a search for custom kernels for cm9 on captivate.
I havent seen any yet, but who knows. I am used to simply stunning roms and the moto droid one. That was great! SS/chevy~ would always have links to the latest kernels avail. for the current builds etc. Good job too.
SO... the search continues.
*Mystery: If I cant even change cpu settings in osmonitor (up or down), yet it lets me enable root mode, what does that mean? The greyed out overclocking area in perfomance settings (up or down)???
I need to learn more"!"
As mentioned, glitch kernel b6 is a great ics kernel. Flash over CM9 and install nstools from the market to control all the kernel settings such as oc/uv, voltages etc etc.

The options are greyed out because the stock kernel currently doesn't support overclocking. Glitch is awesome, and Semaphore kernel is pretty nice too.
Sent from my CM9 ICS i897 Captivate
IcyGlitch for OC, and Semaphore for 400MB mem.
Well Glitch has 387 MB of free RAM
both kernels are good
I want my 13 MB! They are unused so occupying them is unforgivable. IcyGlitch is solid kernel, and I hope 400MB will be added.
