What is the best kernel for CM7 based ROMs? Opinions welcome...

Subject asks it all...., but please explain reason.

All I know is that I can only hit about [email protected] 1GHz on Quadrant.... CM7 2.3.3 ... not sure if its this EVO or what but my white one always hit 1250 on stock ROM stock stock... It hit 1550 on CM6 final. I'm not sure if its the ROM because I don't have that phone for comparison.. (stolen)...
My 3G speeds are also very slow.. sorry if off topic. Id like to know if a different kernel would help the Quadrant score.

Ok explain to me how your rant about quadrant has anything to do with the op' s question? Besides quadrant means nothing Imho . And the new quadrant will give low numbers.
I have tried just about every kernel around and
SavageZen ranks up there pretty high .
stock cm7 is a close 2nd for me and my phone .
SavageZen has sbc built in just a heads up .
from my phone duh

SavagedZen by FAR is the best kernel. The battery life I had with the SZ kernels on CM7 was unreal.
And SBC dangers are a myth. Stop freaking out about that.

I have to say SavagedZen.
Oh and there's a thread that has no-SBC versions floating around here somewhere.

Savagezen cfs is what my phone agrees with. your options are stock, savagezen, and tiamat. I would try different ones and see what works for you. Remember to give a kernel a day or two to settle in
swyped from my cyanogenized and gingerbreaded EVO

In my opinion the best CM7 kernel is the CM7 kernel

Savaged zen... no question. The SBC thing does make me worry, though (and 0.2.1 doesn't have a no-SBC version).

[KERNEL] [BFS] DrodSpeed-2.6.32.36 (4/12/2011)

Here's the new kernel guys. Just been hackity hacking the hell out of hacks, and got things up and running.
The default speed is 998MHz, to overclock, you must use an app like SetCPU.
Change Log:
Since 0.5: [/U]
Please note, the version number is for my personal tracking. For you guys, you can call this 0.6 if you'd like, but here's 1.6:
Adjusted undervolts
Added one more frequency (1.036)
Finally got Smart Ass governor to where I want it, so battery should improve on that setting
Tiny RCU
SLQB Allocator
Backport of 2.6.39RC2 OnDemand governor (thanks, Imoseyon)
FPS Cap raised (thanks Adrynalyne)
Updated Ashmem driver (Thanks, Cyanogen)
Low memory killer adjustments from CM-Kernel
Death Ray mode for flashlight
Audio and Battery Charging tweaks from Adrynalyne
Wifi PM=Fast in standby
Debugging stuff removed for better performance
GPU+ from CM. This has been in for a while, I just found out it was in place a few hours ago when I tried to implement it
Since 0.4:
Reverted to BFS v357 for better battery life
Since 0.3:
Changed to arm-eabi-4.4.3 GCC instead of 4.4.0
Updated kernel to 2.6.32.36
Undervolted more on the low end, and added undervolts to the mid range
Since 0.2:
Updated BFS patch to v363
Undervolt a little more on the low end, add frequencies up to 1.8GHz
Since 0.1:
Neon/Cortex Optimizations
Bug fixes and WiFi fixes
Tweaks to Smart Ass Governor
Initial Release:
Patched in BFS
BFQ Default I/O Scheduler
Smart Ass Governor added
Interactive Governor added

Sweet.. Thanks for working so hard on the tbolt stuff. Much appreciated..

Man glad to see all your work on the ThunderBolt! Thanks for everything!

This thing flies. Thanks for sharing the kernel.

Your kernels are awesome! I hope you make some AOSP kernels too when AOSP ROMs come! Thanks for your hard work!

[KERNEL][5.10.11][2.6.32.21] Kernels from Adrynalyne (Now on Kernel Manager!)

Well how about that, Adrynalyne, I gots me a new kernel! (4a) Keep this up and I'll have to sport ya some beer!
(I think I already owe you a case)
Sent from my ADR6400L using XDA Premium App

thank you kind sir!

ohh downlaods 4a FAST

Smooth as always, don't bother downloading anyone else's kernels.

Any chance I can get a 4a thats 1228mhz at stock volts like the kernel we spoke about from te.zip?
I will buy you a beer

Ughh, seriously adrynalyne?! So I was all happy with Drod's kernel yesterday, now I think I might just have to flash these kernels (b or c) to test out because they look THAT AMAZING! You developers are just aweomse for the Thunderbolt! So many options! I love it! I don't know who I like most! Thanks again

I'm loving the b kernel. Nice work! thanks!

A couple questions before I make my decisions. Is 4a the follow up for Kernel2.0 from the previous thread that was posted (i am currently using adryn kernel 2.0 and wasnt sure if this was based on that). Second. If i wanted to install the oc kernel just for the heck of having it, if I didnt overclock it and left it at the regular 1ghz, would it still run at a higher voltage and affect battery life or would it be the same volatage as 4a until you actually overclocked it? Please let me know. Thanks.

Any chance we can get a pure stock kernel as either a zip for clockwork or a bootloader install so we can revert if needed? I think the one in rom manager still breaks wifi. Thanks,

There is a boot.img file in the original basic debloat thread which I believe is stock also the stock kernel on rm is stock and wifi did work for me with np.
Just reread what you asked for obviously the boot.img has to be applied in fastboot with adb. But again rm does work.

Just flashed the 4a kernel and everything is smooth as always.. thanks man

You can clock it with setcpu to 1228 and get the same result here. Is that ok?

Yes, it continues from 2.0.
If you use an of kernel and choose not to overclock, you will not run at the higher voltage.

Hey does the stock kernel wake at 768 using smartass? It feels like there's some wake lag

Good work.
Good job as always. I have a quick question. This new awesome kernel runs undervolt and only overvolts at speeds greater than 1.3GHz?

if i just install 4.0a, I do not need to install set cpu correct?
This phone at 1ghz is plenty fast

Possible bug, when screen is on and using smart ass clock never drops below 768. When using on demand it does. I was running protekk's battery sipper before this and smartass would indeed dip below 768. Is this by design? Is that how smartass is indeed supposed to work?
edit: I see that you metion smartass is not working completely correctly

Great work
Great work.

Best rom for battery life and speed?

I started out with cm7 but the battery life was so-so. I tried a few other roms and kernel variations but nothing really stood out. My last rom was oxygen 2.1.4 using the netarchy kernel, but I was only getting about 1200ish in quadrant and oxygen seemed a little unstable.
I went back to using the new cm7 RC and the trinity UV kernel and the battery seems OK and i am getting around 2700 in quadrant.
Are there any other rom/kernel combinations that i should give a shot?

Don't base the ROMs speed on Quadrant alone, Oxygen is really fast.
Don't let an outdated benchmark test decieve you.

Correction: Dont let benchmarks deceive you.
Benchmarks regardless of what it is is pointless.

It was more that oxygen seemed unstable on my phone. I might give it another go if the new cm7 battery life sucks.

You might want to check that out. CM7 battery is fine for me. Like I said, Netarchy's 1.3.6 kernel (or 1.3.4) is a NECESSITY. use that and undervolt it using proton voltage control or setcpu and use the suggested volts suggested by proton (-20 across the board)

My nexus is coming to me with infinity ill test between that and others

+1 for matr1x. Most stable kernel Ive ran on my Nexus so far.

really? is it the best kernel matched with stock rom? but i already flash other custom kernel, what am i supposed to do? just flash matr1x over it or need to wipe cache/dalvik first? thanks!

Guys i just wanted to know which kernel is great for battery on ics ?? And till when can we see custom kernels on jb??
Sent from my GT-I9300 using xda app-developers app

You won't see any custom kernels for JB until we get kernel source.. as far as a good kernel for battery..? They all are mate. Every single kernel has at least 1 happy user that gets great battery life. Of coarse mileage is gonna vary. My suggestion is to try em all. Spend a day or two with em and see how they do with your setup. It should be noted that any kernel/ROM combo is gonna need a good day of battery drain and a full charge to really see how she does!

Love it how you use "she" for kernel. :good:
Anyway, I love kernels optimized for battery so I'll share my experience:
phenomenal - One of the best out there, this was built solely for battery. I've been using this in my early ICS days. I could ask nothing more.
siyah - This one is a complete package. You can under/overclock or undervolt CPU and GPU. Has a lot of tweaks, my favorite one is what they called EARGASM. Awesome
galaxsih - I'm currently using this kernel. Aside from battery optimization, there are also some tweaks integrated. Build is almost daily, the developer always update the kernel,
These are just the kernels that I tried so far and these are based from my experience.
