EzyICS Kernel v1
for 6800 For Stock XXLQ1 (Austrian) Roms
FEATURES - Version 1 (31/07/12)
1) Built from GT-P6800_ICS_Opensource_Update1.zip
(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:
rsize=130048
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)

Installation:
**Important***
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:
(THIS WILL INCREASE YOUR BINARY DOWNLOAD COUNT OR WHATEVER ITS CALLED)
sudo heimdall flash --kernel zImage
(zImage is in cwm flashable zip file)
or
2) Flash in the CWM
p6800_EzyICSKernel.zip
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)
Cheers,
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.

Yeah!
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
Idem...installation ok with Recovery Custom v6.....I test my machine for The moment......all is ok....nosoftbrick!
+1 for your appli!

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 ?

It will not change the partition structure.
Have you tried heimdall. I would suggest try using one of the first released honeycomb firmwares as it should be a wipe one i am guessing.
Once back on hc then flash ics.
Worth a try.
So by flashing this kernel i can overclock in Setcpu to 1600mhz?
Applied this server over ICS Quckisilver 1 pre. Works perfect. Udervolted by 50 throughout the full spectrum.

Hello
I tried many times to access device using heimdall but i receive error
Initialising connection...
Detecting device...
ERROR: Failed to access device. libusb error: -12
I tried Zadig as well but no luck at all , any suggestions ?
CM9 ?
I'm taking from past experience that this will not work with cm9? am I right? If yes Could you make one for cm9 for my p6800?
Verry much appreciate your work! I love OC UV-ing!!!

Are you in download mode. I use linux for heimdall so if its a driver issue you will need to specific ones for your distro. Besides having a faulty emmc you should be able to get back to working state. you will need to repartition i suspect but try flashing first.

Cm9 is pretty much vanilla android /linux - so different enough to be incompatible but could be done. This version is a long way off before i could do so anytime soon.
thanks for this awesome kernel.
If anyone has found a way to decrease brightness A LOT below factory thresholds, I would be delighted to know.
Thing is way to bright in a plane or in bed.

Fastest kernel I used!
3400 quadrant, without overclock! Very snappy
Hi,
I'm coming from MCR fr17 Fear Kill edition 10.. it is using the 2.6.32.8 kernel.
My questions are as per below (Sorry I'm new to android devices and trying my best to learn):
a) When flashing a new kernel, I just put it in my SD card and flash it in recovery correct? Or do I need to perform a wipe before doing so? Need to clear any cache etc?
b) For those that have tested this kernel, care to upload the stable voltage for 1000 mhz, 1200mhz and 1300mhz?
c) What if I undervolted it so much that it isnt a stable voltage? Will my phone be a brick?
Thanks to all that take the time to guide a noob like me.

In Pimp my CPU, use the stress test to see if its stable. Use the settings without saving it so you dont boot with those settings. But just to make sure, make a backup of the rom if absolute everything f*cks up.

Currently I cant even run a CPU Stress Test. When I do, the application will be forced closed.
Do take note that I havent flashed in this new kernel yet.. Using 2.6.32.8 atm
I flashed this Kernel with Stock ROM, but I found that my existing Pimp my CPU not work anymore. Please suggest use with version is fine, Thanks.
Same, this kernel doesn't support PimpCPU I believe. Nevertheless, it's the most stable kernel that I've tried so far...
What advantages are their of converting to ext4? Looking for a good kernel current running modaco fr17 will this be ok?

I'm actually not looking for an OC, I was looking for a UV.
Sorry if it is a noobish question but wat advantage does this bring over stock kernel?
Sent from my LG-P990 using Tapatalk
This kernel provides ext4 support. And a small fix I believe. So the advantage is a general speed improvement with phone usage.
Guys, my O2X just got updated (via LG PC Suite) to v10d. I already rooted it, but can anyone confirm if this kernel still works with it?

is this working for MoDaCo FR19 Fear Edition 12.2 ROM? because i get stuck at the lg logo.. or maybe can someone list down the exact steps to flash this kernel..
Hi guys!
This kernel is for stock/MCR ROMs only. I've tried to combine all the best bits from existing kernels into this one. This is based on the stock LG kernel.
First of all special thanks to Benee/Cpujuste since a lot the changes are from their kernels.
Features of the kernel:
* OC to 1500 mhz (minimum is 500 mhz but if you don't change it 300 mhz will work)
* GPU/AVP/VDE have been overclocked
* noop I/O scheduler
* Disabled all LG debugging messages
* 64 mb hack
* EXT4/CIFS built into the kernel
Few other misc changes to the kernel config. This is my first kernel so take it easy on me

ok thank
applied at FR18b2, booting ok, did some testing now :
1.) very positive (for me at least) : LG Gallery works fine with this RAM hack kernel !(zooming ok without black bar !)
2.) LG videoplayer plays 1080p fine !
3.) videorecording with camera mod works fine @ highest settings
4.) quadrant @ 1000mhz : 3218, quadrant @ 1500mhz : 4761
5.) Linpack @ 1000mhz : 36.418, Linpack @ 1500mhz : 54.793
overall : phone seems very snappy even @ 1000mhz, vibration o.k.,
If it´s stable the next 10hrs, i think i will stay with this one, thx !
--------------------------------------------
bugs i found yet :
bootanimation is interrupted when starting 2.nd or 3.rd time (not a big problem)
O2X reboot is not working (reboot & reboot recovery) , or is it because of new CWM recovery 4.0.0.2. ?
tethering not working (tried wifi)
somebody tested the tethereing options with this kernel?

just do a nandroid backup first, when you choose advanced restore, you can only restore kernel if you want, but i would advise you to make full restore if you need to, cause one module (wireless.ko) seems also different ...
not working on stock rom. cant boot
just had some freeze when playing aroung with pimpmycpu, selecting different scheduler & undervolting,next reboot ended in bootloop -> reverted to MCK r14 ...
seems to be more stable at the moment ...

Information about kernel, really, this contains everything (almost)
This is based on the newly released LG v10e kernel sources. Now works on both Froyo and Gingerbread stock and MoDaCo based ROMs. Will not work with CyanogenMod based ROMs.
There are 2 versions now, ext3, and a separate ext4 version. Make a backup before flashing especially the ext4 version, in case if it goes wrong.
Features:
- EXT4 built in (finally)
- OC/UV support, overclocking upto 1400 mhz - use pimp-my-cpu (other apps may not work)
- SDRAM, VDE and GPU overclock
- Voodoo Sound
- BFQ I/O scheduler
- SLQB Memory Allocator
- CIFS, TUN
- few other little tweaks inc some designed to improve battery life
- new wireless.ko module
Credits
- Cpasjuste for work on oc/uv, and learnt a lot from his posts etc.
- Beene for some of the tweaks to improve battery life
INSTALLATION
- Be sure to REMOVE "boot settings" from Pimp My Cpu before installing the kernel to reset default values.
1. reboot to CWM
2. Clear cache
3. Advanced, clear Dalvik
4. install zip from SDcard
5. Reboot

fps kernel by dr4go
This kernel is based on the newly released LG v20Q sources, but also includes every (still) needed fix from imperticus' NeoBlaze kernel. It should work on both Froyo and Gingerbread stock and MoDaCo based ROMs. It won't work with CyanogenMod based ROMs.
Prerequisites:
For the SWAP Enabler you need at least 384MB of free disk space on your /data/ partition. And because the swap enabler just triggers the creation of a swapfile it would be best if the data partition wouldn't be too full when executing it (fragmentation will decrease the swap performance by a whole lot!)
Features:
- EXT2/3/4 built in
- NTFS R/W built in
- OC/UV support, overclocking up to 1552MHz [based on cpasjuste] - I recommend SetCPU (http://forum.xda-developers.com/showthread.php?t=505419)
- SDRAM, VDE and GPU overclock [morfic]
- Voodoo Sound [supercurio]
- VR I/O scheduler
- BFQ I/O scheduler (default)
- SLQB memory allocator
- CIFS, TUN
- SWAP support (including swap notify patch for people who want to play around with compcache)

Personal note: Although I've already been built a lot of kernels (for the HTC Desire HD and also the LG Optimus 2X) I've never released them to public. And I mainly decided to do it, because I'm really really unsatisfied by the performance of this device. Imho it could and should perform a lot better. Join me if you would like to be part of this adventure.
And to conclude with imperticus words: Please also don't forget the 'Thanks button'.

FAQ
1. Does fps stand for frames per second?
No, it doesn't. And I will never ever release this information to anyone here. Sorry folks.
2. What is the difference between the normal and the safe version?
Only the installer. If you're stuck when booting, please try the _safe version. Otherwise it is the same kernel.
3. ...more to follow...
It's a great news to have a new kernel to try!
Edit:
ROM:Gueste2x_v2.1(base on v20e&v20m)
1.After 3 times test, quadrant score is about 2800 at 1Ghz.(HP SR1 is about 3300)
2.Andrev OC can work. I really like Myrt's apps to set UV&OC.
installed kernel on stock gingerbread rom.
got a quadrant score of 5700+ at OC 1.2 ghz (VR I/O scheduler)
changed I/O scheduler to BFQ and my score jumped to 6000+
dr4go,
Will you add swap support to your kernel? Because this is really great feature for our low memory device )
Fast. Smooth. Thanks!

How come these kernels doesn't work with both CM7 and stock (like MCR) based ROMs? Isn't it possible to fix it? Modles? Kernel version? Too much patches provided by LG?
Remember HTC Hero development back in the days; almost all kernels worked independent on ROM. It was an exception (more or less) if the kernel didn't work with a specific ROM.
Looks like a great kernel, but won't flash a stock based ROM over CM.
What about battery life?

Thanks, that is exactly the information I need to improve the kernel. During HTC Desire HD days, there was no better scheduler than the VR I/O scheduler.
Could you also share your results you get with the Anticipatory-, NoOp- and Deadline-I/O scheduler? That way I could select the best one of those.
Thank you in advance.

Noted. Imo you are right, that it would be a great feature for the LG Optimus P990.
Still a lot on my todo list... I already wanted to release it a few days back (as you may have noted I made the last commit on December 12th - since then I'm using it on my device.
Lastly... regarding the todo list: it's done when it's done - and as always: No information released to public before a new kernel it's out.
Stay tuned folks.

Don't get me wrong: I never had CM installed on any of my previous Android devices. My kernel may work on CM, but honestly... I have no clue.
Yes I've also wanted to try CM once, but as you know... you don't have time for everything.
If you are willing to test it, just flash my kernel (but leave also any other working CM kernel on your SDCARD just in case it doesn't boot anymore) and if you do so... please report back... also what works or what doesn't work...
Thanks in advance,
dr4go
I dealt want to try this kernel buy I do not want to f**k up my phone because it is very good with v20o and rock stable.
is it possible to post a stock kernel so I can return without a flash?
thanks

You can find your current kernel inside your zip file of your current ROM. And I doubt that it's the stock kernel you've currently have...

This is your current kernel you have.
To restore it, there are two possibilities:
1) Copy it to your sdcard and flash it inside a root terminal using the commands:
Code:
dd if=/dev/zero of=/dev/block/mmcblk0p5
dd if=/sdcard/boot.img of=/dev/block/mmcblk0p5
2) Copy the boot.img file inside your nvflash folder, and execute:
Code:
nvflash --bl fastboot.bin --download 10 boot.img

tnx ..i made a nandbackup with CWM from my current rom and now a have flashed your kernel so if anything goes wrong I can go back
I will test this kernel for a couple of days for stability and battery use.
what's with the "windowsmgr.max_events_per_sec 120 " ??
LG 2X lcd screen has a refreshrate of 72hz so anything higher than 72 fps (120) could cause tearing in animations (?)
thanks for your effort and time

Max_events_per_sec sets OS(software opengl related params) related frames. While actual hw fps is setted in tegra frame buffer kernel driver. Increasing refresh rate at HW level(at kernel level) gives fake higher 2d (as benchmarking software read hw refresh rate to judge 2D),Infact worsen performance and in a long run it damages LCD Controllers and can be dangerous Actual supported refresh rate is 60hz for mobile QVGA and HVGA and you may find 60-62 with other company except LG.

Before you do anything: This is purely at your own risk and I will not be responsible for anything that happens to your tablet. I flashed it on mine at my own risk.
Compatibility Information: There are 2 different versions. 1 for stock and 1 for Cyanogenmod. Even though the kernels are intended for the 3G tablet it will work just fine on a WiFi only tablet (like mine). This makes the build process less messy.
**Sources Fully documented v1.9 beginner friendly sources now available including the build script. If more explanations are required, please say so. However, remember that the explanations are not intended to be a blind step by step instructions of going from samsung source to A1.
TWRP V2.6.0.0: Please read: do not worry about any kind of "E:A: Render Error". This is a side effect of removing some image files to save place on the recovery image so it will fit on the 5MB. The error simply means it failed to show (render) and image file that it is looking for. This is not harmful at all. If you can't flash the recovery please try the dd method.
V2.6.0.0 3G Download
V2.6.0.0 Wifi Download
V2.5.0.0 3G Download
V2.5.0.0 Wifi Download
TWRP V2.6.3.0: There are no more E:A Render errors. All graphics that were removed are there. Also, the recovery will install supersu if no root is detected. That feature has also been restored. The kernel has been stripped of anything not recovery related to shrink it down. It also has selinux support which allows the "set_metadata" zip installation to work. The download is in the attachments below.

Great to see someone else kernel developing, could be the start of something here... Lol, I wanna give this a try but I think It'll stop 3G working if I flash the 7510 kernel.

Care to try the 3G version I just uploaded? I don't own the 3G version but I followed the same idea for compiling the 3G kernel.
Welcome, nice of you to come to the party
Is there really no one that can test and leave test reports? If i would have been on sammy rom i`d been all over this.
Good luck dev
Flashed, wifi,3g and voodoo working,
well done.... Will test more for you and report back

Awesome. After flashing kernel, my useless wall chargers work. It is very smooth too. Great job.

Finally, the modified kernel!
Voodoo works perfectly.
It can even overclock the CPU to make and perfect kernel.
Maybe 1.6GHz.: D

Overclocking abilities is quite a tall order for my current "skills". After looking at the instructions on how you would do it, the process looks much much more involving than just a manual patch job. Weird thing is that after an initial read through of the instructions it looks like a 1.2Ghz overclock code is in the kernel source but I'm not sure why it's not turned on.

I was quite surprised to discover that the charger that comes in the box of the galaxy tab 10.1 actually sends some kind of "green light" to the tablet to begin charging. If the tablet gets the box charger it actually records "samsung charge !!!r" before activating the charging. If any other charger is connected the tablet records "invalid charger !!!" and disables charging in the next line of code. I just changed it so that it will record "other charger" in stead of invalid and enable charging after recording. (yes, the original code had those exclamation marks after charger).

From the nandroid backup you make before flashing anything.
I don't think a package has been made yet for ICS boot.img.
