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

---

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!

Source code :

• https://github.com/ProjectLense/kernel_omap4_spyder
  - branch extra_kernel_module

Download link :

• extra_kernel_modules_0.1.3.zip - contains all the modules
• init.d_n_governor_installer_0.1.3.zip - optional. init.d installer (load all modules to memory on startup).

Update : Add a preview of Tweakerz app.
- Include all kernel module. Module are loaded from app storage.(no install /alter system partition.)
- Load/unload kernel module on-the-fly (No save setting or set on boot option)
- Set CPU voltage/freq via GUI (No persist option yet)[/LIST]

Easy Install method: (For init.d)

1. Reboot to recovery
2. Install extra_kernel_modules_0.1.zip
3. Install init.d_n_governor_installer.zip (Thanks to core720)

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

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

#!/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

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

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)

1.Load symsearch.ko
2.Load cpu_control.ko

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

Q: How to change cpu frequency & voltage

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

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

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

GB kernel default voltage&frequency table

Id      Freq    Volt(mV)
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

• To view ICS default frequency-voltage table
  

  cat /proc/cpu_control/opp_table_default

• To view current frequency-voltage table
  

  cat /proc/cpu_control/opp_table_current

• To view current CPU & GPU frequency
  

  cat /proc/cpu_control/frequency_current

Will this survive a reboot Whirleyes?

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

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

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.
