vorkKernel-OC/UV Kernel for CM[20111105]

Benee · May 2, 2011

Hi. The following kernel is presented to you by

vorkKernel Team:

- kiljacken
- Benee

This kernel is for Cyanogenmod and Miui. *Could* be incompatible with latest kangs or nightlies (after a kernel update from CM team). No support for stock or mcr...

It's incompatible with MIUI and CM Builds before #177

New vorkKernel Twitter Bot: Here

First I want to make clear that all credit goes to aremcee/arcee/rmcc (man so many nicks

). He did an awesome job with the kernel.
I just tweaked it a little bit to my needs.

Features:

uv/oc support. OC up to 1,5GHz (With E-Peen version)

AVP/System/RAM/GPU OC with E-Peen version

1,2 Ghz for batt safe version.

Special tweaked (working!) Performance and Powersave Govenors which don't lock the freq to one level (they choose between 3-4 Freq steps)

It's even possible to set max/min clock via setcpu or CMSettings!

Voodoo sound. Thanks supercurio! So awesome

Default IO-Sched is Deadline with a special flash storage tweak

Slub allocator

tweaked CFS cpu sched (Low latency)

compiled with a tweaked toolchain (base linaro gcc - optimized for tegra2)

VFP optimizations (vfpv3-d16) and overall compiler optimizations

flags! (more below in the flag section)

A App for easy downloading and configuring. Credits to kiljacken!

The standard part:
I'm not responsible for melted phones or something like that...

The camera is unstable with E-Peen mode (due to AVP OC). After a reboot it needs to stabilize a few minutes (so you break it with every reboot again). Same for Bluetooth. Please don't report a problem regarding this. It's known and can't be fixed.

And the source code here.

Download (Market)
Credits to kiljacken for this awesome app! You need OI File Manager for the app (Comes with CM)!

(and if you refuse to use the app - or the app is refusing to work with you: here)

Only change something, if you want to enable OC - No need to touch anything else (like govenors, schedulers)

What are flags and how can I use them?
I recommend to use the App kiljacken made, because it's super easy for you guys. If you not want to use the app *sadpanda* then you can click this link. This is the file the app is fetching to generate the UI.

The layout is following:
Available for following device/Element style (more below)/the flag you need to add/Flag name in App/Description for general Flag/Choice name in app/actual value you need to add after flag name

If the last two points are added you first enter the flag name and than the value. For example: density230

You connect the flags with a: -
Example: -camera-ring ...

The script is configured to detect flags after vorkKernel-VERSIONNUMBER. So you can add some flags after this.

Element style
c = Checkbox
l = List you can choose things from
e = you can enter your own value

Error Reporting Guide

Start with rebooting, if that doesn't help, reflash CM and then the kernel, and check again. If you're using the updater app (make sure you have the latest version), use the error report function (and describe what you're problem is). If you're not using the app, then post what flags you are using, along with what your problem is.

Additionally I just want to point out that I'm not doing this as a fulltime job, so don't expect daily updates or something like that. I will try to fix a problem as fast as possible but in some cases it can take a while.

If you want to support me you can sign up on dropbox via my referral link or just push this nice thanks button .. If you want to donate you can donate to aremcee/arcee/rmcc something. I'm learning C and linux and vorkKernel is my learning project and it is a hobby for me. Anyway if you still want to support a poor student, I have a link in my signature

Thanks to:
arcee + the whole CM Team
morfic for all the avp oc tweaks and other stuff
thalamus (for saving me going crazy with the toolchain

)
Erasmux
All guys that made pull request and contributed in any possible way

Donators to our project (app or kiljacken's donate link)
the android community

and a very big thanks to b3ndech0 for his buildbox.

Thanks, this is very much appreciated

This kernel is amazing! Nice work with the filename flags. It's brilliant! This way we don't have to have the same setup, but can enjoy both CM7 and the kernel.

I'll try this kernel later. Will wait for CM7 getting more optimized for our devices first. 2000 Quadrant scores out of the box just don't cut it - I don't want to overclock to 1.4 GHz just to reach speeds of MCR FR14 ;-)

Planning on including any changes from kholk?

More things will be in it soon. And Quadrant doesn't matter. CM feels better in normal use (except a few problems but it is a really good starting point).

Yes I know it doesn't really matter. Although, generally speaking, higher scores means the software is more optimized to the hardware; framework, kernel and/or drivers.

CM7 should be able to smash the performance out of the LG stock ROM without problem...

Thanks for you kernel additions! Subscribed to this thread now so I can follow your progress.

vekkio · May 2, 2011

is this kernel for a stock rom?
thanks

Nah. You can boost quadrant to oblivion via data2ext for example on desire/nexus but it didn't helped in real life performance. The sql sync disable doesn't help with real usage, but boost quadrant etc. So many things which doesn't improve real usage, boost quadrant. Like deleting your /system

(pro move...).
But yeah in some parts you are right and optimizing drivers boost it too + help real use performance, so I will do this too.

Really? Just read the title: vorkKernel-OC/UV Kernel for CM. For Cyanogenmod. Not stock...

seems the IO from quadrant score still low, is it same sqlite hack with paul that one?

yup. patched cm, then compiled this and added it to update.zip.

Haaahaa yeah u flash away hahahahha

EDIT:- No only joking

DONT PEOPLE READ

emprize · May 2, 2011

ok, flash this kernal and using cm7 oc to 1.4, quadrant get 31xx

edit : fail to exec smartbench

svceon · May 2, 2011

Benee any chance you could add the OC support to the CM settings?

Sent from my LG O2X CM7 Nightly

Yep but this would break pimp my cpu support and I think pimp my cpu is the better deal. A easy user interface with undervolting support. Awesome! .. so no I won't add it to cm settings

Renegade_Rulez · May 2, 2011

Awesome OC in CM7 makes it even better

spences10 · May 2, 2011

I know I'm going to get flamed for this but how do you o/c once you have flashed the kernel? when i open setCPU its already at the max 1g when i go to the CM settings there's no frequencies to select in the cpu management option

is it different on the tegra chips as opposed to qualacom?

Benee · May 2, 2011

Ok if I understand the changelog from kholk correct, most of the changes are already included (don't know exactly because he didn't copied the commit names and sums the function up). One commit isn't in it because it introduced the graphic glitches. vfp3-d16 support and compiler optimization will be added with next update. Then most things are in it.

Is stated in the OP:

So I compiled it with uv/oc support via pimp my cpu.

Pimp My CPU can be downloaded from here: http://xdaforums.com/showthread.php?t=1018411

Nah no flaming

. You need pimp my cpu for it. Cpasjute did some kernel hacks to enable oc and add a uv function. That means you can undervolt without compiling the kernel again. Unfortunatly it isn't compatible with setcpu..

The kernel seems ok; I tried OC till 1200 with 50-100 UV (depending on OC).
What's very good with CM7 (and this kernel) is battery life, 30-40% more compared with Modaco ROM (till FR14).

Anybody have tried higher frequencies (1300-1400)?

Thanks a lot.

Thanks a lot.

I have been using this all day running 1300Mhz @ 1200mV - normal use with wifi on - 84% battery left after ap. 12 hours
