OK so i think I've messed up the settings on my kernel. Its lagging bad. I was trying to use kernel tuner but there are way too many tweaks that I just don't understand. Does anyone have a tut on how to use it or a thought on an app that works easier?

Just hit the Thanks on that post because I ran this Kernel for a long time on my OG EVO. It was awesome. Great Battery life, good performance, excellent :thumbup::thumbup::thumbup:

This will be my last post in here unless I decide to pull out my OG Evo to make it strictly a wifi and MP3 player...Thanks for all the amazing work ca1ne it was a pleasure using this for so long!

Instructions
Apply with your preferred custom recovery.
For Kernel Install
Make sure to wipe Dalvik Cache and Cache.
For SBC
And make sure the phone is fully booted before plugging it in.
For HAVS with sysfs interface
You will be able to use Vipermod to change the voltages. To be able to save changes you will need a rom with init.d support baked in. The kernel has already been undervolted, but since everyone results vary depending on their devices, this interface will allow you to drop it lower, just like you have been able to in the AOSP roms.
For Audio Boost to turn on and off
For USB Fast Charge to turn on and offCode:Audio Boost On echo 1 > /sys/kernel/audio_boost/aboost Audio Boost Off echo 0 > /sys/kernel/audio_boost/aboost Query Audio Boost Status cat /sys/kernel/audio_boost/aboost
The below code will toggle it in the terminal, but a cool way to turn it on and off would be to support the original dev who put this mod together, chad0989 by purchasing his widget that controls this version of usb fast charge as well as the patch version. LINK TO WIDGET
Thanks to Capt_Throwback for finding out a reason for some of the lag complaints. It appears that the Vipermod script installs an older copy of busybox onto the phone. I have attached a copy of the vipermod install script that does not install any busybox.Code:USB Fast Charge On echo 1 > /sys/kernel/fast_charge/fast_charge_usb USB Fast Charge Off echo 0 > /sys/kernel/fast_charge/fast_charge_usb Query USB Fast Charge Status cat /sys/kernel/fast_charge/fast_charge_usb

Github19Updated OP to v08.
Please note specifically the addition of EXT4. if you use a2sd you can type: a2sd check
in the terminal app, and if it says EXT4 yes, then your rom and kernel now can run EXT4.
I have also compiled some No HAVS versions for those who have difficulty running underworld
please try these out, their voltages can not be modified, hopefully this will allow others who have
been running classic/nitrous due to their phone's restrictions to have some fun on underworld.
Please let me know how this version runs for you, thanks.18I think I found a flaw in many of the implementations of init.d support in sense roms..
It almost appears that init.d only runs on first boot and then is disabled..
Example. If I format all partitions except sdcard, flash a fresh ROM, flash my test kernel that includes a script, then boot, the script makes the changes.. If I then make changes in the script and reboot, I get no further changes..
Example 2. I format all partitions except sdcard, flash a fresh ROM, do a first time boot, go back to recovery, flash test kernel with the script, upon next boot, no modifications are made.
When I get time I'm going to play with the ram disk of a ROM, repackage it with the setup I found in CM7, and see if it works... If it does then we have a solution to get rid of needing to use script manager and other apks.
though if that is true, would need the ROM devs to update their roms... Though I could make some boot.imgs for popular roms...
So I am excited to see if this theory works..especially since the test kernel has a configurable file that let's you turn on and off audio boost, usb fast charge, governor, scheduler, etc18Updated to v0.3
I was trying to figure out how to get the front facing camera to work before releasing, but i haven't cracked it yet, and with the updated source up to possibly a month or so out I figured I should update what I have done already... please let me know if smartassv2 behaves better now
list of changes.

Tweaked Smartassv2
Fixed SIO to be default scheduler (again, lol)
Added Interactive Governor16Lets use this post finally
Tips and Tricks
1. If you are usinig V6 SuperCharger with kernel I/O tweaks. Please uninstall the I/O Scheduler tweak. Failure to do so may casue random reboots. (Thanks Kelldane)
2. Please navigate to the system/etc folder and scroll down until you find the init.post_boot.sh file and either delete it or move it to a safe place on your sd card. More Info (Thanks Leeboy)
3. When using smurf, do not use the battery saving settings for Smartass V2 otherwise in most cases it will generate lag on that governor. If you open the 45smurf file in etc/init.d and remove the section with the governer tweaks the lag will go away after reboot. (Thanks Pennie77)
4. Ensure that your busybox binary is up to date. (Thanks Capt_Throwback)
