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.

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, 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 ;-)

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.
is this kernel for a stock rom?

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.

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
Awesome OC in CM7 makes it even better
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?

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.

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.

Here I put together perflock_disable update package for Legend stock kernel 2.6.29-5f084974. It is ment to disable perflock on every boot. This package consists of perflock_disable module (now licensed under GPL) from SetCPU app and boot script that loads this module.
Background:
Stock Legend's kernel has performance lock turned on. This means that (unless you recompiled your own kernel) CPU frequency scaling is somehow limited. Default limits are set from 480 to 600 MHz while screen is on and to 246 MHz while screen is off. Furthermore ondemand CPU scaling governor is limited from 246 to 600 MHz. This means you can not underclock you Legend with SetCPU unless you use perflock disable option which you have to set manually after every reboot. And here this "update" kicks in.
Requirements:
rooted Legend of course
kernel 2.6.29-5f084974
busybox
run-parts integrated in init.rc script (/etc/init.d)
Big thanks goes to coolbho3000 who now offers this module under GPL so we can use it outside his cool app.
Good post Blayo, wish it had come along earlier.
I hope more kernels will be coming along.
Sorry... how to install this ?
from ROM Manager ?

Well this is for stock kernel. If you have your own kernel, you could have disabled perflok while you were compiling it and you wouldn't needed this module...

Install it as any other update.zip via recovery mode. But you need run-parts in your init.rc, otherwise the module won't load.
I also compiled cpufreq governor modules (conservative and powersave) for stock kernel if anyone is interested...

This is beyond the scope of this tread. You can try Chef Central but to be honest, if you don't know what this is or how it is done, then this (Android Development) is perhaps not the right forum for you.

Yes, Blayo. I flashed the 806 kernel by dumfuq a week back. Im quite happy with it so far but would like to experiment with more Legend compatible kernels.
I read around a bit and then decided that underclocking and battery save could be achieved by a overclock kernel designed for 'performance' ....kinda like 'having the cake and eating it too"
Nevertheless, I appreciate the ideas associated with your present and possible future shares.
Thanks

Yes of course. Those custom kernels don't have enabled perflock so you can set speed by using SetCPU without loading perflock_disable module.
Well, if I'm frank I have never been fond of overclocking. My goal is just to extend the battery life of these "hungry" devices as much as possible without affecting user experience.
Right now I'm testing conservative governor and have some problems, because SetCPU can't handle switching between governors as it should.
Cheers,

What other kernel versions? Almost any custom kernel does not use perflock hence no need for perflock disable module...
Just to let you know guys... SetCPU 2.0.3 now supports perflock disable set on boot, so there is actually no need for this script any more...
I downloaded mik kernel from his git repo and I patched it to add BFS Scheduler (0.404 patch works very well) and to set smartass governor to default.
I use it on CM7 Beta 6.5.2 and it works!
DOWNLOAD: http://www.multiupload.com/917W030Y00
EDIT: ZIP file is unsigned!
What is BFS scheduler used for and how does that help CM7 6.5.2 apart from setting default governor, Waiting for the patch, Thanks.
bfs - performance wise
cfs - multi tasking wise
i hope tun.ko from mik' s rom can be on this kernel since the tun.ko on mik's,rom is not updated, openvpn is not working, and i need it badly
Sent from my LG-P500 using Tapatalk
I didn't used BFS because of strange perfomance issues in GB. If this one is ok I maybe try to use it.
About tun.ko: in 6.5.2 it has been built directly in kernel, but I don't have openvpn to test it.

Yeah there was an issue with dynticks and low CONFIG_HZ (phones were affected since they shouldn't really go above 100); it should have been fixed in bfs 404 I've been using it since your 6.5.2 release and no issues have arose (and no groundbreaking performance improvements either).
@cmangalos: actually, CFS is the default kernel scheduler, and is therefore supposed to be very scalable (i.e. works well enough on machines ranging from 1 to thousands of (logical) cpus), while BFS uses a different approach which privileges user interaction and minimizes latency (hence *theorically* improving system responsiveness), at the cost of lower throughput.
for anyone interesting here's an enlightening read: http://www.cs.unm.edu/~eschulte/data/bfs-v-cfs_groves-knockel-schulte.pdf
A.
Indeed! I've tried with higher CONFIG_HZ but nothing good came off it, but in my desktop HZ as 1000 is a good boost.

With 0.404 there aren't bugs... if you want, you can release a new version with CFS and a version with BFS... or maybe you can release flash zip kernel! Or maybe i can do it for you!

im always using openvpn, and when i started to use cm7 roms, tun.kos are always not compatible with the kernel, if you want mik, i can give you servers, username and pw, and use openvpn setting app found in market

Works great can't test wifi right now but everything else works, good benchmark scores (not very high Oc 245/768 performance kp beyond that ). Testing it further.

blink is an app. "Missed message flasher free"
This is based on l0st.prophet's kernel with added support for Nik's projectX and Virtuous Infinity Sense 4 Roms.
Features:
It's still very much in development and Sense4 versions are not in universal flash as they includes rmdisk changes,
firmware and an init.d script that Rom devs need to add to their releases first.
Test it, try it, rip it apart, fix it, break it, delete it. Pretty much do whatever you like with it.
Tell me what you think and report any issues with as much information as possible.
Includes 15 governors:
Brazilianwax
Conservative
Intellidemand
Interactive
InteractiveX
Lagfree
Lazy
Lionheart
Lulzactive
Ondemand (Default)
OndemandX
Performance
SavagedZen
Scary
SmartassV2
And all the usual goodies.
6 Schedulers:
bfq
cfq

noop
sio (Default)
vr

Install Instructions:
S-off Users:
Those updating from previous versions of my kernel only need to flash the corresponding zip file.
Sense 3.6 (Miui) users only need to flash their desired kernel version (wipe cache and dalvik is also recommended)
[highlight]Sense 4 users who wish to change from another kernel must first install a previous version then the latest.[/highlight]
e.g.
You want to install the latest version of Redux Kernel on Sabsa Prime, replacing stock/another kernel:
Flash Redux_0.8_Sabsa.zip first, then latest Redux Kernel version, wipe cache/dalvik and reboot.
You want to install the latest version of Redux Kernel on Nik's ProjectX, replacing stock/another kernel:
Flash Redux_0.3_ProjectX.zip first, then latest Redux Kernel version, wipe cache/dalvik and reboot.
You want to install the latest version of Redux Kernel on Virtuous Infinity, replacing stock/another kernel:
Flash Redux_0.3_Virt_Infinity.zip first, then latest Redux Kernel version, wipe cache/dalvik and reboot.

*The Sabsa Prime Installer might work for other Roms (ProjectX) but at this point are untested. If you find it's working, let me know!!
**Lower frequencies are experimental and may cause issues (CPU sticking on min frequency) on some governors (interactive based) Do not lower frequency beyond the default if you do not know what you are doing.
***The new wifi drivers are a work in progress and you may notice issues on starting up wifi tethering. Current know workaround is to switch off security temporarily, switch tethering on and off and re-enable security. If someone finds a better workaround let me know. The tradeoff is a much more stable and faster connection from my testing. If this inconveniences you too much, just move to a previous version.

To be updated at a later date
The minimum possible voltage has been dropped to 500mV and the minimum frequency has been dropped to 61MHz for testing purposes. They could cause unpredictable issues with your phone, so if you're not sure what you are doing, it's best to at least leave the voltages alone and only reduce the frequency to 245MHz, possibly 184. If youre comfortable testing these settings feel free to do so and report your findings.

Congrats on your 1000th thanks. What I mean by It's not possible, is starting the ramdisk init services using init.d scripts. So creating a zImage universal flash at this stage is off the table and each sense 4 Rom needs it's own seperately created boot.img to implementthe fixes. But you're right about it being possible to have the kernel running on all the sense based roms of course. I have already studied your downloads
I have got a lot of work to do before "my" kernel has the same/similar amount of features that yours does.
2wc not work for me. Nik x

One question, does this include a 122MHz step? I like it for some reason, and l0st.prophet's didn't have it
Thanks mate
Sweet, thanks
If you can, it'd be great to see a fix for reboots when switching cell tower during a phone call
And I'd also like to see the inclusion of BadAss governor

One question, does this include a 122MHz step? I like it for some reason, and l0st.prophet's didn't have it
Thanks mate

I'm actually testing a 61MHz step right now and also added more frequencies and underclocked stock voltages slightly. Looking very promising. Also planning to drop minimum voltages.

Sweet, thanks
If you can, it'd be great to see a fix for reboots when switching cell tower during a phone call
And I'd also like to see the inclusion of BadAss governor

I'll try to reproduce the error, but if you could provide a logcat it could be helpful. I can't promise too much but will try research the issue. I'm planning to add more governors soon so stay tuned

Sounds good Never heard of such a low step for our device, hope it goes well because I am interested

Awesome (ran out of thanks for the day sorry lol)
It happens to me pretty much every time on the train with all sense4 roms
So it's difficult for me to provide a logcat

You can have a test drive if you like. Just the lower step, more steps and 500mV possible min voltage. No more governors yet.
I'll test tomorrow, its 1am here thanks

We're waiting from a year.I want oc supported kernel.Will it be happen ?

no, because our device is not OC capable..... some developers said, its too dangerous with our CPU.

you seem very knowledgeable on the topic perhaps you should try getting into making an OC kernel
there is a thread that one of the guys started working on an OC kernel
have a search through it and see what you can do

i've changed the values in the frequency table (the highest frequency i tried to compile was CPU @ 1.1GHz and GPU @ 350mhz or 400Mhz i can remember it was around +50MHz then the stock frequency , go slow, too high values can be very dangerous) on the kernel sources but i had some truble compiling the kernel and even if i compiled the kernel the network drivers wouldnt work...(see the instructions on how to compile and how to fix the drivers in the kernel sources From SAMSUNG).
anyway i discontinued my work due to a certain "comment" i didnt like and i have no intention of start developing a public release.
Good Luck

Sad to see you stop developing but really just ignore them, just because someone says you suck or whatever and you stop doing it, its really not worth it
[GT-i9195][cm11] - [ROM](Feb.2016)&[kernel](ECOACTIVE & ECOPLUG)(OC/UV)(20151210)
This is a GT-I9195 CM11 kernel highly optimized to best possible performance and energy efficiency.
It may work on Slim (confirmed), AICP (confirmed) and Carbon Rom (confirmed) as well.
It will not work on any Samsung Stock based ROM.
- built from latest avalable CM sources
- CPU OC: 1998 Mhz (light: 1782 MHz) (default and max.)
- reworked freq- tables (unique 108 MHz-steps) for fast scaling
- CPU UV: -50mv (light: -25mv) (default, adjustable)
- GPU OC: freq steps changed to 192-400-608 MHz (light: 192-400-554 MHz)
- L2 OC/UV for extra performance (stock setting is a bottleneck, especially with OC)
- improved bus scaling
- RAM UV
- adjusted msm_thermal to prevent too much thermal throttling under heavy load
- added new "ECOACTIVE" governor and set as default
- added new "ECOPLUG" hotplug driver and set as default
- added FIOPS IO Scheduler and set as default
- added some more commonly used IO schedulers
- added fast random (and enabled via init.d)
- built with official gcc 4.8 with -O3 flags
"ECOACTIVE" is the ultimate governor for lag free performance and good battery life at the same time. It's based on interactive governor. It has a special input gain including the menu, home and back buttons. Separate input gain, fullspeed and eco/screen off phases minimize the use of high frequencys whithout slowing down the device noticably. The upscaling is more agressive during the input phase (default 1s). In the following fullspeed phase (default 10s, set to 0 for unlimited) full performance is allowed. The third phase is configured for battery saving usage while reading, watching videos, music listening or when the screen is off. This ensures maximum responsiveness and best gamig experience along with best possible battery life when reading, listening to music etc.
"ECOPLUG" is an alternative hotplug driver based on AutoSMP. It works much snappier on our device than the stock msm-mpdecision. On default setting second core is down when screen is off.
Everything is fully "pretweaked".
Flash from recovery, enyoy... no need to adjust anything via init.d or app.
Dont flash this kernel if you don't know how to fix problems after flashing !
Make a backup before flashing this kernel !
The hardware parameters are adapted near to the limits of my phone. This means this kernel will not work if your devices hardware cannot handle the OC/UV.
If you are lucky you run the fastest kernel available for your phone
If your phone doesn't run with the "lombartz kernel" you may try the "lombartz light kernel" with less agressive OC/UV.
My latest pure CM11 ROM build (Feb. 2016):
https://drive.google.com/open?id=0B-1RyGtdRvCwWEVfc0ZhTTRzdXc
If you use Xposed framework you need to flash XposedFix after ROM.

lombartz
...updated.
this kernel is amazing but i have a problem when i connect the smartphone at bluetooth radio. In this case my smartphone freeze and always reboot.
sorry for my english
Hi, thanks for yor feedback Have you already checked if you have the same problem with the last official CM11 kernel from 20150105 ?
regards,
lombartz
edit: tested with my laptop as bluetooth- speaker with no problems. My actual Version is heavily tweaked at the Moment but nothing changed with audio or bluetooth.
Anyone else with bluetooth- playback issues out there ?
edit: found a possible reason for the problem. hope it's fixed in new version (see OP)
Thank you for this. Any chance to include f2fs into the kernel?

It's already included, I tested it just now with my actual Version via USB OTG a d could read and write. It should also work with the 20150212 Version.

Strange. My data and cache partition are f2fs and with the f4ktion cm11 kernel all is working well, but after installation of your kernel I'm stuck at the boot logo.

Here is a Version without OC/UV or other tweaks but with all CM Updates. Its about 20% slower than the tweaked Version but more actual than the V20150212.
If this one boots your phone doesn't like my OC/UV settings...

Thank you very much! I will test it and report back! If I understand it right, f2fs support is also in stock cm11 kernel?
I never tried it...

No luck. I also tried flashing the latest cm11 nightly with no luck.
If I remember right I've tried the stock kernel some time ago only formatting the cache partition and this didn't work either.
20150212 working nice with latest Carbon 4.4.4
can you please add option to underclock min CPU to 162/270 MHz?

This is a technically useless placebo feature and doesn' t save any energy.
The HFPLL has to be used to get the lower frequencys and this will eat the saved energy.

Hmm, the reason is the fstab.qcom, /cache and /data is expexted to be ext4.
Can be changed but I dont know how to allow both fs at the moment.

hi, I dont know what HFPLL is (some high frequency PLL), but I trust you
but still, is more battery efficient to hold wakelock with 162MHz than with 384, no? (see my previous post)
But on theother hand, 50mW diference between 162 and 384 MHz isnt realy so large...

I suppose you mean 50 mV ? The lower UV limit is reached at about 384 MHz anyway.
Youre right with hfpll. Only at 384 MHz the CPU runs with pll8.
If you undervolt @ 384 manually as much as possible you will find that you cannot go noticeably lower if you clock down further.
At the Moment I am testing other tweaks that should be more effective an give some extra performance.

If you like to you can test this. But please make a full backup before because i did not test it myself. I don't want to reformat my phone for f2fs at the moment.
If it boots you are a tester for all the new changes ...
This Version will not run with ext4 /cache and /data partitions.

Thank you very much!
After app optimisation the phone reboots and after the reboot it hangs at the Samsung logo. Only recovering the old boot image helps. Don't know if the oc is the reason.
Update:
I've tried oc with f4ction kernel and had also a reboot. I guess my CPU is not the best.

I am sorry. Should not publish something I did not test myself...
What OC Values did you use with f4ction ?

No problem. I'm aware of the issues that can happen.
Normally I use f4ction as it is with 50uv. For the test I oc'ed to 1998mhz.
