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.

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?
I flashed CM 7 a while back and love it, but as always I feel as though I'm not getting the best battery life. With moderate use I'm lucky not to have to plug it in halfway through the day.
Any good kernel recommendations for good battery life? I'm testing SavagedZen's kernel and using it's governor currently. I find it to have excellent life while the phones asleep, but it's a battery hog when I'm using the phone.
GoDm0dE has done wonders for my battery life! Your mileage may vary as all EVO's seem to be slightly different.
Im having a great exp with SZ 2.1.0. Try using the BFS version of the latest savagezen; As to me it seems the savagezen governor works best with their rom versus cm7(if that's what ur using). I personally run conservative or ondemand with a max of 1113 and 245 min. You could also try the new toast godmode kernel! Here's some general info I think you might find helpful.
http://forum.xda-developers.com/showthread.php?t=894880
I've tried a million different kernals and personally I think CM7 just still has some battery issues to work out.
What has become a frustration of mine is that I continually get different results with the same items. In other words. Some days I'll be using the same kernal and ROM release and even the same programs and my battery will disolve right before my eyes while sudden then I'll get great battery life for a day or two.
Personaly I think it has something to do with 3g and wifi issues, because I seem to have random issues with those as well . . . but I don't know enough about all this to back that up with anything more than anecdotal observation.
CM7 + Timat Kernel = EPIC WIN.
If you flash, only use version 3.3.7 or 3.3.8 as 4.0.0 is breaking some cameras.
Toastcfh's GoDm0dE Kernel gets my vote, and that's coming from Tiamat 3.3.8 with the -100mv script from Viperboy. The Godmode kernel is by FAR much smoother and has gotten me better battery life. Toastcfh works on Cyanogenmod so you know it'll run well with CM7

I'm getting the best battery life from this combo, using 3.3.8
I just started using CM7 last week and also love it.
Image give God mode a shot n see how that works out....if not ill go back to tiamat until they fix the issue's wit the 4.0

Sent from my PC36100 using XDA Premium App
Not sure if this helps anyone, but running godmode at 245/1113 vs tiamat at 245/1267, performance governor on both, I benchmark much better on godmode. I know there's a lot more to consider than that but with a lower clock it surprised me how well godmode did. IIRC I got 1333 on quadrant.
Can anyone point me in the direction where I can find the original CM7 kernel to have on hand to switch back to should I so desire? I want to play with some other kernels, but I always like to have the original sitting by just in case, ya know?

I tried kernel manager, but whenever I try to DL a kernel it pauses then drops me back at the kernel selection screen. All I really want is the current CM / CM nightly kernel(s) so that I can try Tiamat or some of the others but still have a fail safe to drop back to without flashing a whole ROM...sighs

Yeah, I have the tiamat kernel...what I cannot seem to find anywhere, XDA, CM forums, way too much google digging, is the CM kernel to fall back to if I do not like the results I get with tiamat.
To sum it up...
What I have:
Tiamat, Savage, godmode, and every other custom kernel...but CM
What I am seeking:
CM kernel in flashable form, and if kernel manager is the magical answer, can someone PM me and you can email it to me since the manager fails to work for me?

Are any end of days users using a custom kernel and it's stable? If so, which one?
Sent from my PC36100 using XDA App
It's going to differ at least a little between you and another user.. You won't find the best kernel for you until you test different kernels.
Look at Tiamat and SavagedZen. Figure out which works best for you.

I agree with this kernel. I use SBC as well, it will stop the 10% drop in battery whenever you unplug it.
Thanks for all the wonderful responses, everyone!! I'm giving mason a shot first, since it seems so popular
I'm trying Mason G - v0.14 sbc uc'd to 729mhz, powersave gov....but I can't find any options to uv/ov. Does set cpu not work properly with this kernel? What app/script should I be using?
for undervolt if it is sysfs HAVS enabled you need to get vipermod. If it just says undervolt then it may have a pre-set undervolt determined by the dev.

On GB is was running this same setup and my battery life was nothing short of amazing. I had a good 15-24 hours depending on use.
best cm7 kernel?
i just recently started using mason. its pretty awesome. before that i used tiamat sbc also no problems. just try which ever ones you think you may like every couple days to see which one works best for you. i also give the kernel about 10 minutes to bake in every time before i unlock it. i dont know if thats been proven to help but it cant hurt and seems to work well for me.
I've been running mason sbc for about a week now. I had to use a combination of vipermod and smurfed out scripts to get the kernel set where I wanted it. I noticed the kernel was set for BFS by default, which I've never been a big fan of, due to its power consumption....so smurfed out let me set the scheduler to CFS, which is much more conservative and doesn't sacrifice any i/o speed, imho. Then I used vipermod to uv -25MHz so it wasn't such a battery-hog. Underclocked, undervolted, and set to CFS seems to be my winning combo!!! I get no less than 3 hours of constant screen time (streaming video, browsing the web, etc.) and enough standby to last me all day so I don't have to carry my charger with me anymore.
With every other android I've ever owned, setcpu does everything I've mentioned changing in this post...so when it wasn't working, I had no idea what to do.
Thanks so much guys!!! I couldn't have done it without all your help....HTC is in a world all its own in the android scene since they use so many different things that no other manufacturers do. It made me want to pull my hair out until you guys came along to help me out
