vorkKernel-OC/UV Kernel for CM[20111105]

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

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.

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.

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.

[driver/libs][jelly bean adreno 2.x.x libs from xperia play]

Here are drivers for ICS/JB from the Xperia Play forums.

Can this do any good for games (HD games?) As far now I am on cm10. All is working well . I do not want yo get screwed up now. If this will for sure improve gaming performance I would like to tty. But please advice this will not effect other performance......

I don't think this will work, because as far as i know these are not actually drivers but shared objects *.so (much like dll files in windows). The gpu drivers are actually compiled within the kernel and the version of these *.so files must match with the version of the gpu drivers compiled within the kernel. So unless those match i don't see these working for us. However i may be wrong, devs can throw more light on this.

Actually all version of CM7 / CM9 for Motorola Triumph, and edowar's have not been built from source. All files have been copied over and built with the source code. Here is a few examples of the code copying
CM7 MTDEV
https://github.com/MTDEV-CM7/vendor/blob/cm7/motorola/triumph/triumph-vendor-blobs.mk#L82
CM9 MTDEV
https://github.com/MTDEV-CM9/vendor/blob/ics/motorola/triumph/triumph-vendor-blobs.mk#L206
CM9 edowar
https://github.com/edowar/android_device_fb0/blob/ICS/device_fb0.mk#L230

Yes i understand that. But afaik edowar had built a 0.32 kernel with newer gpu drivers which is used in bumblebee rom ported from whyzor's cm7. If u use the same gpu drivers(*.so) in any other 0.32 based rom then they won't work without using the same edowar kernel. And i think the sources for more recent gpu drivers are taken from code aurora forum.

You are correct there is some changes for those specific drivers based on the kernel (forgot to mention that ) here is the commits needed for the kernel
https://github.com/Whyzor/WX_435_Kernel-CM7/commits/master
Look at all the commits from Mar 01, 2012 and that will get you in business with those specific drivers.

Actually these libs work fine. tested in cm10 and cm9 for our device

If the libs work fine then, i don't expect any differences, cause the versions will be the same.

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

[Kernel] Battery saver kernel

Update
Here is an easier solution that doesn't require flashing.
Please use this for any new ROMs from now on.
Old solution ONLY FOR 5.10.8 and 5.10.16
This is a stock miui kernel from 5.10.8, with modified ramdisk to limit CPU frequency.
This is a test I made for myself to see how much it helps in battery time to limit the CPU. I'm sharing this, because others might be interested in it.
You need to have MIUI 5.10.8 or 5.10.16. Older versions are not fully compatible. (Vibration not working)
So, finally we have custom kernels?
No, the proper kernel source is not available yet, the kernel image is still untouched.
Will there be new versions?
Probably, as there are other possible ramdisk tweaks that can achieve better battery life.
How much this can help?
I didn't have the time for a long test yet, I hope there are some users here who are willing to compare the results with the factory kernel.
But I can make some points:
This won't help much with standby time, as the frequency there is already much more limited.
This will help the most in situations where the CPU is the biggest drainer, like games.
Is this going to slow down my phone?
Theoretically, it will be slower. However in real life usage, I can't tell the difference.
Why wouldn't you just use an app like SetCPU?
None of those apps I tried have worked.
Can this be done without flashing a new kernel?
Yes, you only have to update the frequency in KHz in /proc/cpufreq/cpufreq_limited_max_freq_by_user.
For example (with root privileges):
Code:
echo '1500000' > /proc/cpufreq/cpufreq_limited_max_freq_by_user
However, this will reset after a reboot.
The attached file can be flashed under recoveries. TWRP tested.
Or you can extract the boot.img, and flash it in fastboot.
xm_kernel.zip will limit the CPU at 1.5GHz.
xm_kernel_1200 will do 1.2GHz.
Version 2 will do the trick Ched666 suggested, thus reducing the time spent at maxfreq.
Version 3 will not disable the touch boost, instead it will replace perfservscntbl.txt with boost to 1183MHz and 2 cores.

Reserved

Looking forward results and tests.

Thanks for the heads-up. You probably need 5.10.8 for that to work.

I know. I just a flashagolic

ill be testing this later..nice work buddy

Test on miui 5.10.8, it works!
And later manually change value to 1200000, works without lag. But after reboot maxfreq reset to 1500000.
Can you make the same kernel, but with maxfreq 1200000?

That is just a basic MediaTek source, it's missing drivers and configuration for our device.

I think it is more easy to control the value by implement init.d on our device.

OP updated with 1.2GHz kernel

Xmister you really do a great job. I renember I used your kernel when my phone was still HTC one x and then I changed to use iPhone 5s ,6, and dropped few weeks ago. And then I am back to android envirnoment and still flashing your modded kernel. Many thanks for your contribution.
And BTW, I think the 1200 kHz really help in get away from the battery draining problems.

4pda users found interesting thing... When touch a screen, frequency increases to maximum.
But if write 0 to the /proc/cpufreq/cpufreq_limited_by_hevc and set read only permissions, this bug disappears. And no maximum freq when touch a screen.
I tried it, and phone is much less heat, and works at a reduced freqs.
ADD: make mod to xm_kernel 1,5 GHz with this tweak

Also made modification ))

No need to touch cpufreq_limited_by_hevc.
If you want to control the touch_boost, try this way.
Find the file in system/etc/perfservscntbl.txt
CMD_SET_CPU_CORE, SCN_APP_TOUCH is to control how many cores when touch boost.
CMD_SET_CPU_FREQ, SCN_APP_TOUCH is to set the value when touch boost.
Save after modify and reboot your device.
By @Ched6666 's way is totally disable touch_boost

v2 is compatible with 5.10.16 release?

Testing helium in temasek, for now all working right and cpu freq. goes to 1728Mhz. Very similar to last stock cm kernel but with usb fast charging :good:
I have a question @tommons (or sombody): Why do you include KSM? In Tangerine kernel it made the device laggy, increasing the power consumption due to the continous work of cpu cores and soon many of us saw that this feature wasn't good to our Xperia Sp. I always leave it off and better overall performance is achieved.
In init.d options of Kernel adiutor we can see the entry 01tangerine. Delete this entry is the same that going to /system/etc/init.d? I suppose that is.
BTW, great work and thanks for your dev time.

KSM (in v2, UKSM) is there as an option. Nobody forces you to use it It uses more power but the result is a better RAM management.
Yes you can delete 01tangerine from Kernel Adiutor too.

Trying v2 with carbon 5.1.1 seems everything OK..good work man ;D

Overclocking?
Can you build a overclocking option from this Kernel, In Tangerine Kernel my Cellphone is stucked on 1444 MHz on all gorvenors, Can you do it? A Overclocking to 1.94 GHz or more ?

Flash the stock boot.img of your CM build (if you have CM+Addons, it would be better if you flashed the boot.img of the Addons you have installed on your device), enter TWRP, install Helium.
Or, in an easier way, next time you update your CM nightly flash Helium instead of Tangerine!

Overclock needs some work and I'm very busy at the moment. Frequency fixes will come very very soon. In the mean time you can flash v2.1, which hasn't got any issues with frequencies.

@Tomoms I am not able to install v2.2 on cm 12.1 using twrp it says unpacking kernel and nothing happens I have to hard reboot.anyone know how to solve this?

Good! Well, actually that's bad, but I expected it. Will fix ASAP (that is, unfortunately for you, on Sunday/Monday).
Use v2.1, it doesn't have problems.
For the others: I remind you that this doesn't mean v3 is buggy. This bug appears only on certain devices confused and mine is one of the "lucky" ones. So the best thing to do is to try v3 and see if you're lucky or unlucky. Hopefully, the bug will be fixed with v3.1.

Good! Well, actually that's bad, but I expected it. Will fix ASAP (that is, unfortunately for you, on Sunday/Monday).
Use v2.1, it doesn't have problems.

CPU frequency table finally fixed? Needs testing.
Test: Yes, All gorvernors and I/O Schedulers is working with 1944 MHz, Tested!
Thank you, Tomoms

Is TRIM support planned? I think that it is essential for device with such slow flash memory.
As for now I'm using heavily customized Tangerine 9.2 + last Xenon HD which gives great performance, but has issues (inaccurate GPS, big lag after locking the screen, touchscreen not working couple times a week and a few more). Tested latest CM12.1 + Helium 3.1 for few hours and it looks promising, but feels slower than much more bloated Xenon HD + Tk9.2 (used since September) possibly due lack of TRIM support.

You can use the command line utility called fstrim or mount the partitions with the "discard" option. The latter way is more difficult because it requires unpacking the kernel, the ramdisk, and then repacking everything.

Swap crashing problem is resolved in v3.2?

I think that it was my mistake - I cannot remember if I enabled root before issuing TRIM - shame on me
I am using Trimmer utility and running it resulted in instant execution without returning trimmed size in gigabytes pointing that either root was not enabled or TRIM was not supported. Judging by your reply I can assume that TRIM is supported so I think that I'll make second attempt to CM12.1 when touchscreen issue is fixed* or CM13 when camera will be working.
* I just read that @Adrian DC fixes has been merged in 3.2! I will check that kernel as soon as I can! :angel:
