EzyICS Kernel v1

for 6800 For Stock XXLQ1 (Austrian) Roms

FEATURES - Version 1 (31/07/12)

1) Built from
(Thanks Samsung for broken config settings. / Took me ages to figure out some kernel issues!!!)

2) Various compiler optimizations (neon etc.) ( Debug stuff remains for now but will be taken after some more mods are added )
So should get smoother / more optimised in time

3)Mali state tracking disabled

4) Removed MMC_CAP_ERASE (BrickBug)

5) /etc/init.d/S* script support

Add your various tweak / ramscripts from custom roms etc. here

6) Added Pegasusq Governor - (recommend as it deals better with multi-cpu devices like our tabs but may require some tweaking)

7) Overclocking Support upto - 1600 mhz

(ICS changes how frequency control is implemented so not as easily overclockable as honeycomb.)

Fixed CPU Boot Up frequencies to default values / not overclocked settings

8) Undervolting Support:

Some of my settings - (ALL DEVICES will be different)

I have only tried undervolting at these frequencies so far 200 / 500 / 16000 hz (As these are the most used)

So far running pretty stable on:

1600 mhz -------------------> 1300mv
1400 mhz -------------------> 1250mv
1200 mhz -------------------> 1175mv
1000 mhz -------------------> 1075mv
800 mhz ---------------------> 1000mv
500 mhz ---------------------> 875mv
200 mhz ---------------------> 875mv

Use SetCpu to change voltages or cpu overclocks.

9) Slightly undervolted GPU voltages

(As ICS is not as overclockable as honeycomb - needed to reduce heat)

Reduced by 50mv for default GPU levels

10) Bootanimation support

place in /system/media

11) in built CIFS support

Changed Max_BUFFER Size to max 130084

Thanks to Pinkowl for first supporting this.

In cifs options put:


12) NFS share mounting.

13) UDF & ISO support - i.e native bluray disk support.

Other optimizations & stuff - to be added.

Believe me this stuff takes a whole lot of time to do & test - with high risk etc.

Please support my works and further development on 7.7 tabs by purchasing my apps (only 1 for now on google play. Latest version adds MTP/UMS switching for 7.7 tabs)



Make sure backup your device first in CWM.

As this is a kernel only - it does not flash over your data/apps/system etc you should be able to simply restore boot.img from advanced restore settings in CWM if things go wrong. I have done this myself.

I am still using my previous cwm (honeycomb based kernel) and it is working fine for me. So should any other honeycomb based kernel cwm recoveries should be ok too)

1) You can either simply flash zImage using heimdall:


sudo heimdall flash --kernel zImage

(zImage is in cwm flashable zip file)


2) Flash in the CWM

No need to wipe data cache

( I need someone to confirm that CWM flashing works, as I use heimdall)

Usual disclaimer - flash at your own risk.

(Souces code changes added below)


List of Reported Issues - to be addressed in next version hopefully.

Although there is no reason to wipe data / cache etc when using this kernel or restoring stock kernel.

1) Wiping from within Android ICS may cause boot loops.

If you insist of wiping within Android ICS - please go back to stock kernel- first restore (stock kernel) boot.img from andvanced restore / in cwm. then do a wipe

Alternatively - just wipe in data/cache in CWM and you should be fine.

Cwm works fine. Noticeable perfomance increase.

Good to know.

This just a base kernel really (some unnecessary things left in) - should get better and smoother in time

Hello ezynow

Does this Kernel solve issue with internal memory partitions ? , I have my Tablet issue with custom ROM and I had to move DATAFS and FACTORYS Partitions in order to make Tablet work , it doesn't accept flashing by ODIN but it can work with Aroma ROM , so can this Kernel help my problem to restore lost partition are ?
