[KERNEL MODULE] Extra modules pack v0.1.3 (feat. overclock) [OMAP4 kernel 3.0.8]

whirleyes · Jul 6, 2012

Some extra kernel modules for you & me.

Modules :

filesystem

ntfs.ko (read/write support)

cifs.ko (with extra attributes)

kernel hacking

symsearch.ko (Unexported symbol finder by Skrilax_CZ)

CPU scaling governor (back ported from other dev)

cpufreq_interactiveX.ko [@] (interactiveX V2 governor by imoseyon)
early suspend support and hotplugging

cpufreq_hotplugX.ko [@] (hotplugX governor by imoseyon)
early suspend support and tweaks

cpufreq_smartass2.ko [@] (SmartassV2 governor by erasmux)

cpufreq_pegasusq.ko [@] (Samsung multi-core governor)
based on modification done by Gokhanmoral

cpufreq_boostedASSv2.ko [@] (a modified smartassv2 governor)
ported from BMc08GT

CPU/GPU frequency control

cpu-control.ko [@] (Tweak CPU frequency & voltage to your like)
my 1st kernel module. based on milestone overclock & opptimizer.

I/O scheduler

sio-iosched.ko (Simple IO scheduler)
based on Noop, Deadline and V(R) IO schedulers. In android world, simple is better

modules with [@] mark requires symsearch.ko to operate

These kernel module will work for most Motorola omap4 device. (kernel 3.0.8 only)

Disclaimer : I don't write all of these modules. Only make a few changes/tweak for it to work on our device. Enjoy!

Easy Install method: (For init.d)

Reboot to recovery

Install extra_kernel_modules_0.1.zip

Install init.d_n_governor_installer.zip (Thanks to core720)

Install guide for adding init.d script via Script Manager - SManager app

Code:
1.Extract all *.ko files from extra_kernel_modules_0.1.2.zip to /system/lib/modules
2.Open Script Manager, Create new script / modify existing script

Code:

#!/system/bin/sh insmod /system/lib/modules/symsearch.ko insmod /system/lib/modules/cpufreq_interactiveX.ko insmod /system/lib/modules/cpufreq_hotplugX.ko insmod /system/lib/modules/cpufreq_smartass2.ko insmod /system/lib/modules/cpufreq_pegasusq.ko insmod /system/lib/modules/sio-iosched.ko

3.Save to /system/etc/init.d/

Q: How to load a cpufreq governor

Code:
1.Load symsearch.ko
2.Load your choice of governor
3.Enable it

Code:

insmod /system/lib/modules/symsearch.ko insmod /system/lib/modules/cpufreq_interactiveX.ko echo interactivex > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

Q: What is the best cpu-freq governor

maybe this will help you choose/tweak

CPU Governors explained

Pegasusq Governor

Q: How to load cpu frequency/voltage (underclock/overclock)

Code:
1.Load symsearch.ko
2.Load cpu_control.ko

Code:

insmod /system/lib/modules/symsearch.ko insmod /system/lib/modules/cpu_control.ko

Q: How to change cpu frequency & voltage

Code:
echo id frequency(Mhz) voltage(mV) > /proc/cpu_control/tweak_cpu
example :

Code:

echo 0 196 980 > /proc/cpu_control/tweak_cpu echo 1 500 1195 > /proc/cpu_control/tweak_cpu echo 2 750 1320 > /proc/cpu_control/tweak_cpu echo 3 1000 1388 > /proc/cpu_control/tweak_cpu echo 4 1350 1410 > /proc/cpu_control/tweak_cpu

ICS kernel default voltage&frequency table

Code:

[B]Id Freq Volt(mV)[/B] 0 300 1025 1 600 1200 2 800 1325 3 1000 1388 4 1200 1398

GB kernel default voltage&frequency table

Code:

[B]Id Freq Volt(mV)[/B] 0 300 1025 1 600 1200 2 800 1313 3 1000 1374 4 1200 1375

** voltage min : 830mV, max : 1410mV

More/Details about cpu_control.ko module

Code:
To view ICS default frequency-voltage table

Code:

cat /proc/cpu_control/opp_table_default

To view current frequency-voltage table

Code:

cat /proc/cpu_control/opp_table_current

To view current CPU & GPU frequency

Code:

cat /proc/cpu_control/frequency_current

Will this survive a reboot Whirleyes?

whirleyes · Jul 6, 2012

NO.. use init.d or custom init to have it persist.

I've upload new version of bootmenu with 2nd-init support today.
Just waiting for Google Play to start distributing it

J.Y.Daddy · Jul 6, 2012

Awesome!
"67.42.17.XT910S.SKT.en.KR" is our Razr(Korea Razr).

is that kernel source has been opened?

Thanks for your work!
I'll try to test on my razr.

see this thread for all link .. ICS source code is now available!

good work

core720 · Jul 6, 2012

I've created an installer that includes support for automatic load init.d modules so they can select with SetCPU or other similar program....

Thanks.. but to be more efficient, I would like to have them separated.

1. User install my module pack. (extra_kernel_modules_*.zip)
2. User install init.d loader. (init.d_n_governor_installer.zip

I tried to use your flashable zip. It doesn't work, but I found that after I chmod 777 the 90module in the init.d folder it works flawlessly. So I think you need to add that set permissions to your script.

*edited for grammar issues. It was bugging me that my You're and Your was wrong.

core720 · Jul 6, 2012

Fix....

robertwhitten87 · Jul 6, 2012

I don't think the ntfs.ko is working right. I just formatted an sd card with ntfs to test it out after loading the module and it pulls it as a blank sdcard.

DJFliX · Jul 6, 2012

Will this work on an XT910? Is the kernel source any different from the 67.42.17.XT910S.SKT.en.KR?

don't blame the ntfs.ko, it's MotoBlur problem.(vold limitation)
You have to mount your NTFS partition manually.

These modules will work on any 3.0.8 kernel

Yeah, I realized that after I commented and was playing around some more. Motoblur is the one throwing the blank sd card issue, not the system itself.

So I think it's time to go back to playing. I'm loving the new governor.

mattfox27 · Jul 7, 2012

does anyone have an init.d script they could throw up to run one of these on boot?

I flashed the zips and have not been able to automatically pick the governor while in setcpu.

I loaded up terminal and did the commands you posted but those didnt work unless i substituted /system/lib for /system/bin. Doing that I can now select interactivex. I'd love for the init.d scripts to work so I dont have to fumble around with this every boot. My rom does have init.d support.

Is there a reason for the difference on my phone? I have a razr maxx and running the newest kernel from build 214 and on Arctic rom.

Thanks.

garywojdan81 · Jul 7, 2012

Thank you for this. I loaded both zips & init.d works perfectly for me on an OG Razr running the stock 211 rom/214 kernel combo. Everything is available to select & it all runs at boot. System Tuner Pro is what I use to select the governor/scheduler settings.

Thanks for the modules! They work perfectly. I was wondering if its possible for you to write a script/module that would support editing vsel values for undervolting the cpu. Would be really helpful in extending battery life.

Try check OPPtimizer Projekt, maybe tekahuna has recompile it for ICS.
