Hey guys

Even if this wasn't the way i planned to release my stuff, i'm gonna do it anyways now...
I usually planned not to release my kernel seperately from my rom, but my lappy just crashed hard this afternoon when i was about to push my sources to github... so everything's gone

except for the kernel, i pushed it on saturday... luckily

Now, back to topic

[*]Unlinked GPU from CPU
[*]Overclocked GPU to max 600MHz (Please see 2nd post for instructions)
[*]Overclocked LP to 600MHz by default, up to 700MHz by user
[*]Cpuquiet framework enabled (with balanced as default gov)

The INSTRUCTIONS
Download the latest kernel version from HERE

The easy and fast way:

Copy the zip to your sdcard

Code:

[STRIKE]CPU OC[/STRIKE]
[STRIKE]Unlinking the GPU[/STRIKE]
[STRIKE]New I/O schedulers[/STRIKE]

  - Slightly improved multitasking

[B][04-29-2013][/B] initial release

Additional stuff:

GPU OC more than 520MHz:
For daily use, i set the max GPU rate to 520MHz. This should be enough.
But if you think, you need more heat to cook something for example, you can go up to 600MHz. Therefore you need to set a new max GPU clock limit. You do this using the following commands:

Code:

echo '<GPU_clock>' >/sys/devices/system/cpu/cpu0/cpufreq/gpu_oc

with <GPU_clock> being your new desired max clock rate

Setting LP max rate:
You have now the ability to set the max speed of the low power core (5th core). You can do this using the following command:

Code:

echo '<LP_clock>'  >/sys/devices/system/cpu/cpu0/cpufreq/cpu_lp_max

with <LP_clock> being your new desired max clock rate

Changing the voltage table:
You have the ability to change the voltages for the processor from now on. But just because you can, doesn't mean you should. Changing voltages is dangerous! In the worst case, you can burn your processor!
I am not at all responsible for damage, caused my my kernel/your settings!
You can find the interfaces here:

Code:

/sys/devices/system/cpu/cpu0/cpufreq/UV_mV_table    <--- CPU
/sys/devices/system/cpu/cpu0/cpufreq/avp_UV_mV_table    <--- GPU
/sys/devices/system/cpu/cpu0/cpufreq/emc_UV_mV_table    <--- RAM
/sys/devices/system/cpu/cpu0/cpufreq/lp_UV_mV_table    <--- LP core

For using @arararagi's hardware customizations, i'd suggest you to use his toolbox from this thread

Stock builds of Werewolf JB

Hi all.

I'll be maintaining WerewolfJB kernel for stock. The links will be listed on this post. I may also upload experimental kernels.

All credits go to @laufersteppenwolf for his excellent kernel.

For now, the link for WerewolfJB v005 stock is this: https://www.box.com/s/okea8s7pdqcgf5soppbi

And for WerewolfJB v005 CM (with increased voltages and new modules for mobile data): https://www.box.com/s/4d3vxivlcu9ebsku6r4f

Flash it via CWM/TWRP.

Note: Both stock AND CM versions have increased voltage for the 1.7GHz step to 1300mV because of reported instability. Be careful in undervolting since the voltage table is slightly imbalanced, so perhaps -75mV can work for some frequencies but not for others. Furthermore, I removed quite a lot of wakelock references in baseband_xmm_power but forgot to revert them back to the "fix", so if you have any baseband instability please drop me a PM. Also please do report battery life performance, along with a screenshot of your wakelocks and ideally a dmesg. Thanks.

==============================

Experimental versions (for STOCK):

None for now.

I would have liked to release the ROM tonight, too.... but my lappy somehow didn't agree with me

Please test and report back. Also about gaming performance.

Is to flash the Kernel with Fastboot the only way ?
Our can I flash it with Terminal Emulator?

What about battery life?

On official CM when I use 3G Internet, battery drain is very, very fast.

this kernel (together with my rom) lasts about 2 days with mobile data and wifi always enabled

Those are awesome news

when can we expect your rom to be officially released

???

as soon as i've set up my lappy again and re-made all my tweaks and changes

@non4 · Apr 29, 2013

I thought GPU unlink was already implemented, or was this done through init.d? At least people have something other than kholks unstable alpha to play with

yeah, i unlinked it via init.d in the test roms

i wanted to implement it to the kernel, but... you know

elfen.lied · Apr 29, 2013

are newest tegra drivers in?

not yet, but i will inlude them

laufersteppenwolf · Apr 29, 2013

OP updated with terminal instructions

momothecat · Apr 29, 2013

this is a great news, another custom kernel :beer:
but I'm still with zaiben rom (base on stock rom) cause for me cm 10.1 rom still not ready for my daily use. I hope you will build for stock rom too

surely I will try your kernel when I'm ready to move to cm official or when you release you rom

This kernel seems good so far - feels smoother and more consistently buttery. I'll have a look for bugs - I don't know about the governors, though.

For development sake can you verify if gesture typing works properly? Then we'll know if the kernel broke it or the test rom

Nice. Thank you!!!

BTW, can anyone make a flashable zip? Don't have access to a PC. Mine is down.
