[kernel] Overclocked ICS 3.0.8 kernel v0.1 (for 4430 only) with tun.ko

---

Hi All,

Here is a first release of my overclocked kernel.

This kernel enables 1.1 - 1.5 Ghz cpu frequencies in cpu governor.

- 1.1 and 1.2 are with Archos stock voltage
- 1.3, 1.4 and 1.5 are with a slight increase of voltage: 1.4V instead of 1.388V

Usual disclaimer: I'm not responsible if you fry your tablet with this kernel, I don't recommend overclocking at all.

I'm personally a bit against it but as many are interested, here it is. My tablet is apparently very stable at 1.2. 1.3 works a little but eventually crashes. Without voltage increase, 1.3 crashes very early.

Instructions:

- Flash this kernel in recovery along with your build initramfs
- Enable overclocked frequency with your favorite tool (setcpu, cpu boost, system tuner).
- If overclock crashes your tablet, power off with a long press (more than 10 seconds) on power button, then you can power on again and try lower overclock.

By default, this kernel boots at 1.0 Ghz to avoid any issue. I don't recommend using it on 4460, it won't bring you anything.

I also enabled tun.ko if anyone needs it.

Let me know how it runs for you!

great, i'll test it
I report if it works

btw. what did you change in the sources, did you just added the frequencies ?

Yes, with voltage, and removed 1.2 ghz soc check. See attached diff of all changes.

Bonjour et Merci

Fonctionne a merveille sur archos 80g9 jusqu'a 1200 mhz.

encore merci

what do you mean with: don't use it on 4460??
i thought all g9's have omap 4460 cpu??

nope there are the omap 4430, which runs at 1,0 GHz
and the omap 4460, which runs at 1,5 GHz
for last mentioned overclock to 1,5 GHz doesn't make any sense

Only Turbo models have Omap4460 which runs @1.5GHz by default. Other models use Omap4430- 1.2GHz max

lol, yes
i just woke up:P
i thought i had a 4460 it is a 4430:P

Edit:

Did you include a autoroot methode in your kernel???

thank you, so in theory it could go even higher ?

what value defines the volt ?
the 1400000

+#define OMAP4430_VDD_MPU_OPPNUCLE_UV		1400000

or the 0x29 ? :

VOLT_DATA_DEFINE(OMAP4430_VDD_MPU_OPPNUCLE_UV, 0, OMAP44XX_CONTROL_FUSE_MPU_OPPNITRO, 0xfa, 0x29, OMAP_ABB_FAST_OPP),

after flashing this i can't enter sde anymore
when i enter sde i just reboot ?

Edit: working now
i need to hold power button and then select developer then release power button and it boots in developer recovery
