I have installed RR v2.6 and when choosing customized installation there are FLUXI / CM9/ siyah kernel option.
Since I am new to the ROM world my question is which kernel is to preferred when it comes to stability and battery drain for this ROM ...
I have Samsung S2
I've been using siyah kernel for the last few weeks on different versions of resurrection, however for this one I'm using the fluxi kernel to see how it goes. Remember that you can't accurately judge how good the battery life is until a few charging cycles have passed.
I'm using cm9 and not had any problems so far. Not quite as smooth and lag free as siyah or fluxi but battery a bit better, plus music on power amp seems to sound a lot better/bassier. Might be placebo but I like it lol

First off questions go in Q&A but this thread should not exist see this. Locked

I have read enough threads on diverse topics to gather that flashing a custom kernel carries with it some benefit.
I read about faux123's kernel and found the original thread from February. I was going to flash that, but thought I would ask if that version (in that thread) is the latest.
Currently running CM7.02 (last update, no nightlies right now). So obviously, ny current kernel is whatever CM current kernel.
Also, if anyone has opinions on other kernel's (GB at least) besides the one which faux123 has compiled, and which they had a positive experience using, I'd be interested to hear about it.
Faux is basically the kernel God here lol but which version is it? The latest is 2.5.3 if I remember correctly

EDIT: I found v. 2.5.2 and flashed 2.4.8 and then 2.5.2.. Using CFS SV. AWESOME... so far!
OK... well this is where I am having difficulty. I found the OC kernel thread but the link in the post is for a RC3 (version is <1). Also, in this thread re the OC kernel, it did not state it would apply to CM7, but since I know faux is using parts of CM7 for his kernel, I can only guess this would be fine. Can someone confirm this?
Another thread re faux's kernel had both the CFS and BFS kernels, and here the version was 2.5.2. And with regard to this non OC kernel, is the speed on the CFS good pretty good with good battery life... provided, I gather, I set the speed to "interactive"???
There are just a lot of different threads re what seems like a lot of different kernels, so I am trying to get just a little better idea at what version (and where the thread for it is) would be best.
I pretty much use my phone 45 minutes out of an hour. But, I have only had it unplugged for 2 hours a day on average since I got it. I expect to be using it off the AC or USB charger for more like 6 hours/day though... I just want to make sure the battery isn't 25% after 3 hours.
I didn't want to start a new thread so I hope someone sees this....
But its been about 12 hours with faux's 2.5.2 kernel, and it is great except its really hot by the battery. Anyone else notice this? I have it set to interactive, and an OC stop at around 1600 MHz...could this nd too high?

How many .35 kernels are available? I'm only aware of Umaro's and the stock CM kernel. I'm trying to achieve better battery life, so what kernel are you guys using?
So far, using Umaro's, I'm getting regular battery life, nothing special. Haven't tried the stock CM kernel.
Are they any other undervolted kernels available?

There aren't any others so far. Umaro's kernel is really good for battery life, however it's not up to date with the latest kanged nightly from yesterday.
Ahh, I see. Thanks for the info.
What cpu settings are you running?

Right now I'm using a kanged nightly with the "stock" cpu settings of 245MHz min and 1024MHz max, but with the interactive governor. With Umaro's kernel I had at 245 min, 1017 max and the Smartass governor. The smartass is pretty good on battery.
u made all the right moves all i would do is dim screen and keep runnimg apps low.
pimped out g2
btw pyromod 2.0 345 ghz min 1405ghz max on smartass. i fully charge bout 1 a day
pimped out g2
Pershoot released his kernel the other day pretty nice and smooth

Alright I'm sleepy so this will be in rambling form but...
I've tried Umaro's and I'm not sure if it was the undervolting (which I haven't looked into tweaking) but my phone kept stuttering no matter which governor I used. I was using Htcclay's Super CM7 1.8 with cpu set to 245/1113
I also used the stock kernel that's been on CM7 with no problems and average to good battery life (10-15 hours of active use: texting, browsing, few calls, and playing the occasional game)
Most recently I've used Pershoots which I had heard worked great. I myself love it. Almost same battery life as stock kernel but everything felt just a little bit smoother performance wise.
Here's a link to Pershoot's thread:http://forum.xda-developers.com/showthread.php?t=847672
The stock cm kernel in my opinion is finally good enough that it doesn't need changed. I have always flashed pershoots and occassionally others, but it truly does not need supplemented IMHO.

Using Pershoots latest kernel, have nothing but good things to say about his kernels. Always my go to kernel.

You're running that on Vision? I can't seem to find it for our device.
Stock CM7 kernel here. I run 245/806 Interactive with automatic brightness. I've found that when wifi is on, keeping the cell radio @ 2G only works wonders. Wifi is set to sleep on screen off, but not when plugged in. 1 day 7 hours on this charge so far with 23% left. I would consider my use light to moderate.

I'm wondering where can I download the Umaro's kernel. I check out his github (https://github.com/umaro/htc-kernel-msm7x30) only to find out that the source is available.
I'm currently running turl1's v8 with the kernel that comes with it. I've read about people having this issue with faux'd kernel and that they fixed it by using the one is turl's build. I've attached a pic of the Time in State screen from SetCPU.

I am using jokersax 0.3.1. Same issue.
do you guys have profiles set?
Only based on temperature. Do you?
I have profiles set when the screen turns off and such.
I still have idle problems, but its masked a little if you underclock to 912. and with hardware acceleration you can hardly notice it.
I I did have the idling problem with previous builds so I switched to turls1's. When the new 0.3.1 came out I switched back. I also changed from setcpu to antutu cpu master pro, and now it idles correctly.
I'm using turl1's V8 Kang with faux123 025 beta kernel (1.0Ghz), and here is my CPU freq for something like a week.
I use a profile for screen off- 216-608.
Now mine looks a lot better. But I didn't change anything..??
I'm not using a profile on mine either. I think I'm going to try faux's kernel and see if it improves any. I think I would get fairly great battery life if I could resolve this issue. I got down to only 84% after moderate screen time and video and music playback today with over 8 hours off of the charger. Most time was spent in 312Mhz with 608Mhz being the next highest and 216Mhz as the third.

My cpu seems to be working great on turl's v8 with the default kernel. I was getting pretty poor battery life on joker's ROM, but on Turls v8 I'm getting the best I've ever had; stock or not.
Sent from my MB860 using XDA
Running Jocker's latest with the latest Faux 1.3GHz kernel.
Idles mostly at 456MHz.
Something wrong there.
After flashing faux's 1Ghz kernel and setting a profile for screen off @216Mhz it has greatly improved. Although it seems any time the screen is on it never hits 216. My battery life didn't seem to get any better either which I find odd.

another vote for turl fixing batt life.
No idea why some people are so good on faux's but a large proportion have these massive problems.
I switched to turls v8 with the kernel it comes with and now my battery life and cpu usages are great!
told ya, mine looks around the same
tried to feed it back in jokersax forum, not sure if he's picked up on it or not, theres plenty of people saying 'great batt life' but theres enough of us out there who aren't getting that (and whom get decent results with turl). Maybe there are subtle hw differences in certain batches or revisions of the SoC or something like that.

I've never seen my atrix idle like that.
are you sure? Mine idled similar to that in CM7, now CM9 turl build.
In jokersax build (stock kernel) 0.2 I never got below 456Mhz consequently heat and battery died in ~10% an hour increments even if I didn't touch it
What Kernel shoud i use for best Performance/Battery on PA Beta 6 JB 4.2?
Franco Kernel vs Trinity Kernel?

I've not tried trinity but I found that the Franco Kernel seemed to pull off the rather surprising trick of improving performance & battery life.
One huge improvement was to the time it takes to charge the device.
I found that Trickstermod on the play store is rather useful for tweaking the clock speeds for 3rd party kernels.
Hey guys.
Looking for a good kernel for my G2(info in sig) ... Looking for a good overclocking kernel, What do you use?
Any recommendations?
Dorimanx allows you to overclock to 2.8 ghz but what are you gonna use that for? The phone gets extremely hot in very short time. What is it that 2.8 ghz can do and 2.26 ghz can't?
Sent from my LG-D802 using XDA Premium 4 mobile app
Dorimanx is very good if you want to overclock it and keeping battery drain at good level.
Best for me is from bruce.Is absolutely amazing and very snappy...
Thanks guys, Is Dorimanx good for everyday usage too?(without overclocking)
iam using dorimanx 5.8 for 2 days now and its stable until now. no issues at all.
but there is one thing to know about this kernel. it offers alot of options via stweaks but its recommend to use the profile settings that are comming with the rom. they are most stable.
I've used Dorimanx for months now , but switched to Bruce2728 kernel ,and i stay with it.
Very fast , smooth , no lags and very good battery life.
I would recommend bruce's kernel that can be found here.
Fast and reliable, good battery life.

Can't beat dorimanx for jb or kitkat. He's a very hard working guy. He never stops improving things.
Simple Kernel v6 overclocks to 2.5GHz. Simple means only Interactive governor included. Works well. 1%/3hr standby. Testing Vellamo bruce2728's kernel rules in multithreading even without overclocking.
