This is a minimalistic Galaxy Nexus kernel. Imoseyon philosophy is to keep the kernel as lean and stable as possible, at the same time to keep the kernel as modern and close to latest mainstream linux as possible. You will see that my kernels will lack some of the bells and whistles from other kernels.

DOWNLOAD
  • Terminal Emulator not finding my scripts? Read this post.
FEATURES
  • Patched to latest in Linux 3.0.x branch.
  • All unnecessary kernel components removed to make kernel lean and fast!
  • OC to 1.65ghz. Boot speed is maxed at 1.2ghz within kernel (in addition to ramdisk) for stability.
  • User voltage control
  • InteractiveX V2 (screen-off hotplug of cpu1) added. Select it using setcpu if you want to use it.
  • Ramdisk tweaks (sysctl, vm, filesystem speed, etc.)
  • SWAP & zram (next generation compcache) support. Run "zram enable" in terminal.
  • init.d support in ramdisk.
  • lk.conf for basic kernel configuration.
  • HotplugX governor (Hotplug optimized and modified for screen-off suspend).
  • wakelock tweaks for wlan and lte modem
  • lkflash - script to flash latest versions of leanKernel from Terminal (type "su" without quotes, hit enter, then type "lkflash" without quotes and then hit enter)
  • checkv - voltage checking script (for custom undervolting) - detailed at bottom of this post.
  • checkt - script that displays 1) your current temp, 2) # of times you were throttled due to temp "recently", 3) CPU trim type, and 4) CPU silicon type, etc. (sample output)
  • Fast USB charge (by chad0982) and "ffc" toggle script by me. (Open terminal, and type "ffc" without quotes then enter)
  • ColorControl from both CM9 and Ezekeel (compatible with all ROMs). Helpful posts: 1and 2.
  • TempControl - sysfs interface to control the CPU temp threshold. Read these two posts: 1 and 2.
  • Variable GPU OC - sysfs interface to select GPU max speed between 307MHz (stock), 384MHz and 512Mhz. The changes take effect immediately. Check FAQ for more info and how to use it.
  • Custom SR Tuning - override kernel default minimum voltage for SR calibration. More info here and here. V2
  • SoundControl
  • Gamma Control
  • ROW scheduler v4

CHANGE LOG JB 4.3
CHANGE LOG JB 4.2

DIRECTIONS
Uh.... flash the zip in clockworkmod.

I've been sticking with LeanKernel ever since I tried it out on ICS. Good to see Imo's work being brought to the attention of users outside of Rootz.

Working well for for me on 4.2. No issues/complaints so far.

2 hrs 10 min of screen on time.

I am surprised that this thread is unpopular. Great kernel. Smooth and battery friendly.

Yeah. The main thread is on RootzWiki. It is a very popular kernel there. I have had people tell me to try all the other kernels because they're better. I've tried them all and I keep using this one. Its light,runs smooth,and helps battery life. What more could you want .

The most stable kernel :good: !!

Where is the sysfs interface?

Edit: Found it, but does anyone have a link for the newest lean kernel tweaks script by Jake? His download link is down.

My last two days of using the kernel and its great... I never gave any comments for any thread in favor of it but this is first one :)) even franco or other kernels.. They have some hot stuff to offer but at the cost many things, specially battery..this one is optimized for battery specifically...

5.2 seems even more battery friendly than 5.1.1.
I will report after full depletion.
