I had CM7-1.0 before with pawitp kernel.
Today, I flashed the latest CM9 nightly and right now am on the stock kernel.
I have the following kernels with me at the moment:
—Semaphore ICS Kernel from here
—Devil3 from here
My questions:
Which one of these Kernel will give me the best battery life and is fast at the same time?
Will I get a bootloop if I flash either of these kernels over the stock kernel which comes with the CM9 nightly?
There are both BLN and CMC kernels on this page. Which one should I be using?

1. Try it yourself, flashing kernel is about 1 minute. Both kernels are great.
2. Try it yourself, bootloop isn't yet diagnosed. Sometimes it happens sometimes not.
3. there are only 2 versions: cmc (cm colours) and vc (voodoo colours).
Also before flashing wipe cache/dalvik and clear init.d and ns tools

Hi, before you flashing a new kernel, flash first the kernel cleaning script from lipol. then you have no problems with the new kernel.
And what you think about midnight Kernel? I use this Kernel and i'm very happy with them. You have with that kernel a very good Battery life. :thumbup:

Used to always use kernel cleaning script lately Kernel cleaning script gives me boot loop nearly everytime.
Wipe cache, wipe dalvick, clear ns tools and clear init.d is fine.
Of the kernels you have mentioned i have found semaphore to have better battery and to be more stable unless you want to over clock. Or that is my experience anyway.

After using stock cm 9 kernel for quite a while I was curious to try out semaphore and regretted it only hours afterwards...
With Antutu Benchmark App I got 400 Points less compared to stock kernel... after some hours my phone hang up (black screen, ne wake up). Some hours later the next black screen... Finally I got back to stock kernel and I am happy again
Its very fluid and responsive, in my opinion there is really no need für a custom kernel in CM9, only if you need USB Host support and the ability to overclock...
I'm using devil3 kernel and I love it, it's just awesome. I think it's more customizable than semaphore, but a bit harder to set. Anyway, you should test by yourself both of them, remember to flash lippol's kernel cleaner before flashing a new kernel

Devil kernel is the best for me. I love all the options and speed. I over clock to 1.4GHz, use lulzactive governor with smooth UI profile and everything is tuned for performance and I still get almost 2 days on battery. Using cm9

I would suggest devil kernel, it has a very good battery live, some great features like swap or zram
And BTW: Just flash your kernels over each other, no use to flash kernel cleaning script neither wipe dalvik cache. it has nothing to do with kernels ;-)

Devil3 for me too. As well as being fast and having decent battery life, it's the only kernel that had voodoo color. Once you've found the best settings for your screen there's no going back.

Devil3 for me too. It works like a charm. :good:
I'm running CM9 stable with Semaphore 1.3 on 1.2GHz and smartassV2 governor.
Never had any problems with semaphore so i keep using it. my battery lasts for 1 day while running games for several hours, and up to 4 days, if i barely use it.
i know many people don't like benchmarks, but i thought i'd attach my quadrant-score anyways.

I too am using Semaphore 1.3 with smartasv2 governor, no problems here either, i recommend it !
I am newbie so please forgive me, Can some one please explain to me what a kernel is and why it matter?
Also say for example I install Werewolf CM10.1 ROM does the kernel also change to WerewolfJB automatically?

Yes because CM Roms run on different kernels and cant be used on stock or stock based kernels. And wise versa. And Kernels are...well not sure how to explain it. Let me try it. Is basically like a transmission. So better the transmission is so better runs and shifts the car. That's basically on a phone the same. Yes the processor is important but the kernel is what makes everything run like it should. I installed a costum kernel because the original one was so bad in battery life and this costum kernel is much better optimized. No more 10 or more % battery drain in standby in an hour. Battery life was pretty terrible on this phone now it is like a fully new phone with ok battery life.

The kernel is the core-engine all other software runs on. To make an analogy with a car:
The chassis of the car is the phone, the engine is the kernel and the body is the ROM. This is not a very accurate analogy, but I hope you get the point.
Different kernels focus on different keypoints. Some are very battery-friendly, some favor performance, some offer extra functionality to the system, etc..So there is not a one-size-fits-all perfect kernel.
ROM's are usually based on a certain structure, which the kernel has to support. So for a stock ROM you need a different kernel then for a CM ROM. Most ROM come complete with a kernel, a few don't. So if you flash a ROM which contains it's own kernel you overwrite the kernel that is on your phone. So let's say you've got the Optimus Prime kernel and then install the latest CM build, you overwrite your OP kernel and have to re-flash it after installing the ROM to get it back.In your case the Werewolf CM10.1 ROM comes complete with the Werewolf kernel.
Hope this answers your questions.
Hello everybody,
I have problem with this combination ROM + kernel. I see micro stutters when I scrolling between pages in sence5
and scrolling down in contact list. I tested various value in cpu governor. I set up_threshold 50! and smothnesswas better.
But I have battery drain now... Stock kernel seems smothness definitely!!!
ANY other solution in this cause? Or I must still waiting for new HTC kernel base?
Thank you for answers
For a good experience with custom kernel, is better wait the release based on the source code of htc for the 4.3

Okey, thank you for your answer but some users having good experiences with this combination on same base, same rom and same kernel
I still waiting for official HTC 4.3 based kernel and after this I see
Fluid Kernel
FOR KITKAT AOSP ROMS
This is enhancement over basic CM kernel to attain more fluidity, performance and power saving.
There is no heavy modification like NX-Kernel or Mackay Kernel which causes lag eventually.
Kernel is compiled with Linaro Toolchain 4.7-2013.10 and is bug free.
If any bug found other than one already in CM11 basic kernel, please report.
OCed but default max frequency is 1GHz.
Feature requests are welcome except for BLN feature.
Download Link:
http://www.mediafire.com/?4ba44ymbkcx4m
Kernel Source:
https://github.com/neobuddy89/vibrant_fluid_kernel
Latest version:
v1.0
Any feedback/views/suggestions are welcome.
Regards,
Neo
v1.0:
+ Linaro Toolchain 4.7-2013.10 compiled
+ Entropy Depletion Fixes and Enhancement
+ WiFi wakelocks reduced
+ OC Support upto 1.4 GHz
+ Minor network tweaks
+ Reduction in memory reservation for logging
+ Memory leak fixes
+ Performance tweaks
Thanks a lot Neo. You are amazing.
Will try this out on my ROM 11/20
thanks a bunch...cant believe this phone is still running and running like a beast at that.
outdoing yourself for us :good:
Lovely!
I want to click like 999 times!!!!
Very good! Really - performance gains!

Actually KitKat was/is supposed to be a release which will help memory-challenged phones (like ours), so if anything KitKat *is* something we expect ardently and sure as hell hope that dev support won't end now, now that we finally reached an OS version actually suited for our low-ram phone(s)...
Thanks Neo for making a start in supporting us with 4.4 goodness...
Thanks for this rock kernel using it on captivate
If u can compile this kernel on captivate would be thankful
Just the difference is the volume keys layouts
Great work!!
It will be really great if you can compile this kernel also for the captivate!!

Should learn to compile your self. Or switch the volume key layout to revers it back to normal
@sada23 Is this article helpful to your already awesome kernel? http://source.android.com/devices/low-ram.html
I noticed that we have Linux 3.0.x in use, which probably lacks the "tunable reclaim" feature, but could be cherry-picked from the patch in 3.4 branch, as stated by Google:
Support for a new kernel tunable is added in the android-3.4 kernel branch as patch 92189d47f66c67e5fd92eafaa287e153197a454f ("add extra free kbytes tunable"). Cherry-picking this patch to a device's kernel will allow ActivityManager to tell the kernel to try to keep 3 full-screen 32 bpp buffers of memory free.
For those who are in search for Ramdisk source, get it here:

I reckognize that USB thethering is not working with fluid kernel and sada's unofficial KK 4.4. It ends in a reboot.

I would like to see the kernel upgrade. Just ask to remove overclocking 1.3/1.4 GHz, since it will probably kill the smartphone, and my at those speeds just hangs and you have to remove the battery!

Then don't overclock to 1.3/1.4 GHz. Some peoples devices might be able to handle it. Just because yours can't doesn't mean to nobody's can. Be smart with what you do and know what your phone can handle. Mine does 1.4GHz just fine.

Hi everyone,
What is the most stable ROM for the Vivid as of now. I was on the most recent (downloaded from another source that was more updated) DeSensed Vivid 4.0.3 with a Kozmik kernel, but have had problems with lag and etc.
It's important that the ROM has good call volume that is close to that of the stock.
Thanks for helping
