[KERNEL] 7 June 2011 - Froyo OC/UV Kernel

Hi there !
Got my Optimus 2x yesterday, and played with it today
So here is a modified kernel compatible with MoDaCo roms. This kernel will boot with stock values (1000mhz max, default voltage). You can then enable higher states (1200, 1300mhz) with "Pimp My Cpu"! But you can also lower the voltage to get the best of your device Be sure to read the "Pimp My Cpu" post to understand how it work.
Try at your own risk ! May be unstable, i'm not responsable for any damage ... etc
Kernel developpers, you can find some informations on how all this work here.

Same as "2x-kernel-2.6.32.9-fakeShmoo-cpasjuste.5" but with higher overclocking (not recommended), see below.

I did successfully add 216 Mhz frequency to the kernel, but there's a bad news. I did found a hardware limit on the max8907 controller : voltages cant be lower than 770mV. It's why the stock LG kernel runs at 300 Mhz for it's minimal frequency, it run fine at 770mV. So this means that any undervolting lower then 770mV wont do anything, it will still run at 770mV...
Taking the previous discover in account, i didn't add the 216 Mhz state but replaced the (really) too hot 1300 Mhz state by a 1100 Mhz one, so you can probably use that without overvolting (unlike the 1200 Mhz state).
I probably fixed the non booting problem on some roms by adding the required "init.d" script in the zip update package.

Be sure to REMOVE "boot settings" from "Pimp My Cpu" AND uninstall "Pimp My Cpu" before installing the kernel to reset default values.
12 Apr 2011 : 2x-kernel-2.6.32.9-fakeShmoo-cpasjuste.4.zip
A few fix on the oc/uv code which could improve stability
Now use an "unified" cpufreq sysfs devices name. I mean it use the same sysfs names than other oc/uv kernels (at least Galaxy i9000 ones). You HAVE to update "Pimp My Cpu" to version 2.1 at least for it to work.
Cpu sensor is now "/sys/devices/system/cpu/cpu0/cpufreq/cpu_temp"
Freq/voltage table is now "/sys/devices/system/cpu/cpu0/cpufreq/frequency_voltage_table" like other kernels. See this post for more informations.
Uv/mV table is now "/sys/devices/system/cpu/cpu0/cpufreq/UV_mV_table". See this post for more information.
Need Pimp My Cpu version 2.1 at least.
11 Apr 2011 : 2x-kernel-2.6.32.9-fakeShmoo-cpasjuste.3.zip
Back to "normal" releases (with more frequency steps added)
Lower 1200/1300 Mhz voltages, as nvidia recommand 100mV max voltage change between two steps. May not be stable for all.
Maybe fixed some bugs added by the OC/UV modification (some references to old freq/voltage table was still around)
Probably last kernel from me, dev's now have the necessary resources on my github to play around
Be sure to REMOVE "boot settings" from "Pimp My Cpu" AND uninstall "Pimp My Cpu" before installing the kernel to reset default values.
10 Apr 2011 : 2x-kernel-2.6.32.9-fakeShmoo-cpasjuste.2.zip
Test release, try to be as close as possible to the default LG kernel
Now based on new kernel sources released by LG instead paul sources
Only 6 available frequency like LG stock kernel (could prevent some problems)
Maybe fixed some bugs added by the OC/UV modification (some references to old freq/voltage table was still around)
Be sure to REMOVE "boot settings" from "Pimp My Cpu" AND uninstall "Pimp My Cpu" before installing the kernel to reset default values.
9 Apr 2011 : 2x-kernel-2.6.32.9-fakeShmoo-cpasjuste.1.zip
Added cpu sensor ( "/sys/devices/system/cpu/cpu0/cpufreq/FakeShmoo_cpu_temp" )
Added freq/voltage table ( "/sys/devices/system/cpu/cpu0/cpufreq/FakeShmoo_freq_voltage_table" ), see this post for more information.
Added uv/mv table ( "/sys/devices/system/cpu/cpu0/cpufreq/FakeShmoo_UV_mV_table" ), see this post for more information.
Changed unstable 1400Mhz frequency to 1300Mhz (we can't have more than 8 freqency)
Added "init.d" support to be 100% compatible with "Pimp My Cpu"
Be sure read the "Pimp My Cpu" changes which may interest you
Installation :
Copy the zip to external SDCARD
Boot to ClockWorkMod Recovery (power button + volum down)
Choose install zip from sdcard
Select the zip
Recommendations
Nvidia tegra 2 (AP20) drivers as set the maximum allowed temperature to 60°, you should maybe not go further.
Nvidia tegra 2 (AP20) drivers recommend maximum voltages step of +-100mV (+-100mV between two frequency)
Cpu temperatures are already high without OC. After a lot of testing, i would not recommend to OC this device, but for sure undervolt it.

Very nice, looking forward to try it

Great, with some overvoltage it should run 1,5GHz possible you could make a update.zip?

Very nice indeed should get my optimus 2x this week OC-ed to 1.5 would be nice

That sounds good.

does it work to flash through recovery with the 2 zip files you attached?
edit: seems that I have to push them but I'll wait for a update.zip

Nope you have to follow the step here :/
Does someone have a update.zip template ?
For overvolting, i would need to find a way or know default voltage values, i'll take a look this week.

Yes it seems that 1200mhz is not stable enough without overvolting, i just got two games to crash. I'll look at voltages value this week.

Yeahh, i did update the install procedure ... did forget to put all the "shell" command after adb .. sorry

I did found the original voltages so i would be able to change them without doing a mistake

then give us 1,5GHz... LOL

It also seems that MoDaCo kernel do NOT have the 2 cores enabled (not sure of that), cpuinfo report only 1 processor while "my" kernel reports two.
Click to expand...

Negative, CPU-Info seems not to be able to detect two CPU-Cores. At my Device it shows 1998 MHz ... So it seems that with the Modaco Kernel both CPU-Cores are working
BTW. Great Work

I tried, but i stuck at boot too.

SetCPU shows 1998 BogoMips on Stock-ROM, so i guess it works there too.

I think this one is good without an update.zip at the moment.
As it rightly says in the OP this is for advanced users only, an update.zip will simply tempt everybody to have a go. In my opinion, until it's been tested a bit more it's best kept amongst the few.
Having said that, top shelf... 3105!

Hehe thanks for the support
Actually i'm unable to get a stable 1200mhz even with overvolting so maybe something else is happening. I'll try to have a stable 1200mhz before releasing a new update. I also got 1400hz but unstable too :

undervolt and overclock performance and save battery

You can save battery and have great performance by undervolting/overclocking cpu and underclocking gpu, the best way i found is a script in rom toolbox.
i run on maverick 4.5 and try this day on 4.0
and this link :
http://rootzwiki.com/topic/14511-opptimizer-projekt-milestone-overclock-for-omap4-devices/
for me my values are:
for cpu
mpu_opps[3] rate=1200000000 opp_id=3 vsel=61 u_volt=1345000
mpu_opps[2] rate=800000000 opp_id=2 vsel=55 u_volt=1200000
mpu_opps[1] rate=600000000 opp_id=1 vsel=43 u_volt=1100000
mpu_opps[0] rate=300000000 opp_id=0 vsel=26 u_volt=1005000
for gpu
gpu_opps[1] rate=307200000 opp_id=1 u_volt=1125000
I started all the values with romtoolbox and create a script at boot
open rom toolbox / open tools / open scripter / then create new script
script name:
overclock
commands:
#su
echo 3 1200000000 1345000 > /proc/overclock/mpu_opps
save, and click on your new script and select "at boot"
re create a new script for the other values, for me a total of 5 script, 4 for the cpu and one for the gpu
The governor is mot_hotplug or boostedassV2.
I tried a lot of voltage values, the more stable are here for me.
I think this run on many rom, not only on maverick
The dev can implement this in rom ?

Can you export your scripts and upload it here?

Thank you, i imported scripts, set it at boot, rebooted but its not working for me.
In set cpu my max freq is still 1000.
im on ICS Gummy rom, i will try on another ROM

Try in terminal emulator (on rom toolbox or other)
To verify your value or your script after boot
#su
cat /proc/overclock/mpu_opps
To validate one value (for example)
#su
echo 3 1100000000 1360000 > /proc/overclock/mpu_opps
Then press enter
Then re verify (cat /proc/overclock/mpu_opps)

[Q] Change Governor Before Flashing

Is there a possible method to change default governor like "ondemand" to "conservative" before flashing the ROM ??? What I mean is can any user change any ROM value in any file to achieve the same so that ROMS which does not have CPU Control ( Like AOSP ) can boot up with conservative governor ???

AFAIR,in kernel config u need to change this while compiling:
# CONFIG_CPU_FREQ_DEFAULT_
GOV_PERFORMANCE is not set
CONFIG_CPU_FREQ_DEFAULT_
GOV_USERSPACE=y
Or use an init.d script,copy paste this and set permissions
echo "governor-name" > /sys/devices/system/cpu/cpu0/
cpufreq /scaling_governor

Does it have the overclock module and does it load properly? As far as I know if you have stock kernel the only way to overclock is via module.
Check system/lib/modules if you have x8oc.ko. I suppose that's the file you're going to use to overclock the phone. If you don't then download it and put it there.
If you have it, open Terminal Emulator and write:
su
dmesg | grep x8oc
You should receive the output that it loaded successfully. If you get no output, the module isn't running.
If you have it and it isn't running, then open Terminal Emulator and write:
su
insmod system/lib/modules/x8oc.ko
This should run the module and allow you to switch frequencies. Start testing the frequencies with whatever CPU app you use.
When you're satisfied with the performance, add the insmod command to hw_config in system/etc and echo the clock value that suits you. You can find more information about this in the x8oc thread. Don't worry about reboots, make a backup before trying, and make sure you don't edit the hw_config file until you're sure the clock is stable.

Thank you it helped. I can now overclock

I think the question above is to be asked in the ROM's specific thread. There are several guys in that thread that are more than willing to help you.
