[kernel][TW][ML1 v4.0, 1/11/14] Leankernel: Minimalistic Kernel by Imoseyon

TokedUp · Nov 26, 2012

Imoseyon gave me permission to link his kernel here on XDA. Please thank Imo on here or RootzWiki, and please donate to him if u can.

ICS and JB kernels are available.

v 4.0 is the newest version for TW JB 4.3 ML1 only.

Older versions are available (4.1.2)

Experimental builds are also posted on RW. I personally dont want to link them here since I cannot help if something goes wrong. So keep an eye on the RW thread if you can help in testing.

Link to OP/ICS kernel http://rootzwiki.com/topic/31329-ke...el-minimalistic-kernel-ics-v13-jb-v03-112512/

All credit goes to Imoseyon

Please feel free to post results from Roms.

OK so running this on jelly beans b 4 and it is super fast. Works like a champ! Great work imoseyon. I tried ktoonsez and this way smoother on touchwiz. Like butter baby!

Are there any custom governors with this kernel?

No just three. Not as many options but already set out of the box so to speak. Changed my io scheduler to deadline and let her rip.

I hope to have interactiveX running on it before the 1.0 release.

Running fine on clean Rom 5

does not work with Taste of Beans 3.5k at all..

color flux
removed boot animation
reboots
battery gets SUPER HOT!

had to do a batt pull, boot into recovery, and go from there.

Ran fine when it first booted...benmark scores were very high...running very smooth...

Then after a reboot things got kinda wonky...

Seemed to be running rather hot...and I seemed to lose the ability to control clock speeds with system tuner...

I could sit in the app and watch the max/min speed change without any input from me...and setting it to 1512/384 manually would only last a matter of seconds...

...after the first reboot...i would set clock speeds...do something like run a quadrant test...go look at clock speeds and max would be at 1900 even though i set it at 1512...if i ran antutu at the end of the test it would come back as 1134mhz inn the system info even though I set it to 1512...

Based on my observations...it seems like the moment you put the CPU under any sort of stress...the clock speeds wig out and you lose the ability to control them...

Edit: I can repeat it every time I run a benchmark...quadrant, antutu, smart bench, whatever...the kernel completely loses the ability to control clock speeds..I noticed a similar problem with the Ziggy kernel that synergy uses...

The only non stock kernel that has worked right is 747...and in its ktweaker app there is a setting to "lock" clock speeds so that other apps can't change them...it specifically says "like benchmark apps." It may be something to look into...

Its a shame because on the initial boot up of this kernel my phone had never felt as smooth or performed as well...

This is due to thermald and is normal behavior. I include a tweaked thermald in my ICS kernel but I don't really like the way i implemented it. I'm going to think of a different way to handle this for my JB kernel.

So it would be "stress" related sorta...but more heat related specifically?...its a bummer because my phone does not like 1900mhz at all...and really starts to heat up/lag at that clock speed...

So if the kernel is going to "reset" all the time I'm gonna have to stick with 747 because its the only one (except stock vzw jb) that sticks no matter what I throw at it

Edit: I will however say...the kernel is completely compatible with Synergy 118...and like I said before...when it initially booted the phone was screaming...and performing better than ever...

So keep up the good work and I'll keep my eye on things...

I didn't run your kernel on ICS...wishing I had tried it out now lol

Despite what a previous user said I'm running this on tasteofbeans 3.5 with no issues. I've ran both 0.2 and now 0.3

Has anyone ran this kernel over CM10 nigthlies?

Sorry to hear Met. My phone has never run so well. I'm not experiencing any heat ups or problems set at 1700mzh. When I I run Vellamo it lists the kernel max at 1900mhz but when I check setCPU its locked at 1700mzh. I ran LK on ICS and it was simply amazing. It was the only thing I missed moving to JB. Plz remember that this kernel is just days old and it will continue to get better with updates from Imo. Keep the reports coming guys, it's the best thing to do to help.

jdub251 · Nov 26, 2012

What I've noticed is that neither this kernel or ktoonsez like Android tuner or system tuner. They make the kernel go haywire if using either one. I don't know why. That will b why ur min max doesn't match in k tweaker when u open after reboot. I use set CPU for imoseyons kernel and it works great on EVERY tw new base rom and so far has been the best I've tried and i test extensively. Lol.

Any chance of Call Recorder kernel support Imo? I only ask becaues several of your kernels for other phones I have owned did support it.

I would not use KTweaker with this kernel. I remember reading some where its specific for KT kernel. I have had issues using Android Tuner and system tuner on previoulsy used Rom/Kernels as well. I use SetCPU and it works great, I know its a paid app but its so worth it especially if you plan on using custom kernels. Theres a free setCPU version floating around but that app isnt supported anymore.

droidstyle · Nov 26, 2012

V.3 locks my cpu to 1900mhz...so i reverted back to v.2 and all is well. 11180 antutu bench mark @ 1520mhz, 10080 @1900mhz

TokedUp · Nov 26, 2012

For the ppl not needing to OC try v.2, u might have better results.
