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)

INSTALLATION
1. Remove "boot settings" from Pimp My Cpu to reset to default values
2. Reboot into CWM (v5.0.2.7-r2 recommended)
3. Install zip file from SDCARD
4. Reboot
Kernel sources: Github
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.

[KERNEL] [2.6.29.6] [Flashable-.zip] [LAGFIX][BFQ][Oc][Uv] #3 "Patches 'O Klick"
So after countless hours of failure, I finally found my issue. It was an embarrassing one, but O well. What we have here is a fully stable kernel for the Vibrant. I have spent many hours on this and have been running it on my vibrant for some time now. Be sure to read the changelog for full info. At 1.2 Ghz I was getting MFLOPS scores pushing 10 MFLOPS! Performance is surely nice on this one. Another thing to note is the undervolting on my kernel. This will give optimal battery life for users. So, please enjoy, and post and errors with a logcat
This is compiled for the stock ROM. It will work on FrankenTwiz, Bionix, and many ROMs. Let me know what ROMs you try it on, and what ones it works best with.

This would be my first time using an oc/uv kernel. I know to get the oc, I have to go into setcpu and put the scaling to conservative, which I've already done. Ran quadrant, and got a score of 2790!
Great kernel!

ok ima give it a shot and report back
This is gonna sound noob but here it goes. I've never done research on what exactly kernels are and this is all new to me.
This new kernel I can flash like Rom will over clock my device to 1.2ghz or will it give me the option to? Can overclocking hurt my device in the long run?
Does this come with tools to over and underclock when I need to?
Any other info would be great. I'm on Eugene Franklin twis v2, no voodoo or lagfix yet.
Any other info would be awesome.

Works awesome on Frankin-Twiz update 1
buttery smooth
Works with Bionix
Installed, booted fast. Thanks for your hard work.
Good to see you back, King! Do you think this will work ok on Eugene's Hybrid R3? Also, I know some Vibrants (like mine) didn't like jacs OC kernel. Same issues here, or did the undervoltage kernel fix it?
Sent from my SGH-T959 using XDA App
Can we have info on how to revert this kernal back to stock if needed?
Very nice, glad to see another person compiling Vibrant kernels. Have you considered including the voodoo beta4 in one of your future builds?
Working fine on Vibrant 9
Will this work with a lagfix already installed?
What does the bluetooth patch do? I'm hoping improved A2DP quality, please say its so

Kernel builds are currently tested against a stock rom and CM7, while they may work unchanged in other roms, your mileage may vary.
All source code is available on my github (see signature).
Be safe, -ALWAYS- make a backup before flashing!

*Standard Disclaimer: All packaged builds are provided with no guarantees as to their safety. By flashing, you assume any and all potential risks that running a custom kernel might entail.*
*A note to overclockers: If your phone is unstable when running an overclock speed, your particular phone probably can't handle that overclock and you should choose a lower clock.*
All kernel builds mirrored HERE.
*It is generally a good idea to wipe Cache and Dalvik-Cache when flashing a new kernel build to avoid certain problems usually related to Dalvik-Cache*

Changelog:
Revision 1.4.1:
- Updated Ezekeel's Touchkey Dimmer to version 3.0 bugfix 4
- Integrated Ezekeel's Deep Idle mod, current to bugfix 5
- 45,333 rabid naked bunnies were harmed during the making of this kernel
Revision 1.4.0:
- Revert a patch that caused random reboots in certain usage situations
- Added Ezekeel's backlight dimmer sysfs interface (See instructions in second post on how to use)
Revision 1.3.9:
- Return to Deadline as default IO scheduler, using BFQ v2 could cause bugged encounters such as a never ending boot
- Applied kernel tweaks from the recent 2.3.5 OTA (mostly relevant for sprint users)
Revision 1.3.8:
- BFQ updated to BFQv2-r1
- Some build options that may have contributed to random reboots have been modified
Revision 1.3.7:
- Voodoo Sound driver updated to v10
- Testing out tiny rcu
- Touchscreen tweaks are no longer applied by default on boot. Users can still custom tweak touchscreen settings if desired
by editing /system/etc/init.d/98touchscreen and rebooting as before.
Revision 1.3.6:
- Wifi driver changes, rolled back some code that was causing problems
- Added Cyaniris' touchscreen tweaks back in the form of a user customizable sysfs interface (courtesy of work by Cyaniris).
Users can set custom values by editing /system/etc/init.d/98touchscreen , followed by a reboot for the changes to take effect.
Currently the default values are set, users that find the defaults not optimal might want to try some suggested settings by Cyaniris
of 35 for touchthr, and 20 for noisethr.
- Corrected a bug that would have caused reboots and/or other assorted badness when having the phone sleep at a frequency other than 800mhz
(Confession: I was an idiot and forgot to move over this fix from my 2.3.3 kernel trees when making the new kernel trees for 2.3.4, woops!)
Revision 1.3.5:
- Wifi driver updates, bugfixes
- JHash3 Added
- Cpu cache clearing fixes
- New compiler toolchain for builds, using gcc 4.5.2
- Interactive governor adjustments
- IO scheduler set to Deadline, seems to have a nice balance in performance
Revision 1.3.4:
- Remove touchscreen adjustments for now, they were causing problems on some phones.
Touchscreen tweaks will be revisited for a future build
- Add auto group process scheduler for CFS builds
Revision 1.3.3:
- Touchscreen adjustments that may improve touch response
- Update Voodoo Sound driver to version 9
Revision 1.3.2:
- Update BFS builds to BFS404
- Add Simple IO Scheduler and set as default
Revision 1.3.1:
- Smartass screen-off speed adjusted to address unresponsive programs during screen-off
- Smartass adjustments to improve responsiveness
- SLQB slab allocator added to help optimize memory allocation performance
- Some build configuration changes that may improve overall feel
- Ondemand governor up threshold adjusted to improve battery usage while still maintaining responsiveness
Revision 1.3.0.12:
- Adjustments to smartass to improve performance (there is probably still room for improvement)
- Default I/O Scheduler set to CFQ (previously BFQ), this may prove to be more stable in certain situations
- Some adjustments made to the CFS scheduler that may result in a better overall feel to CFS builds
Revision 1.3.0.11:
- Added Smartass Governor
(Not enabled by default, use setcpu or CM's cpu performance
settings to change if you want to try it out)
- Raised voltage cap to 1600mV for crazy people that
want to turn their phone into a reactor ;D
- Set config options in 2.3.4 kernel builds that should enable
NS4G compatibility for our newly arriving sprint friends.
Welcome to club nexus ;D
Revision 1.3.0.10:
- Update kernel base to 2.6.35.13
- Excessive stuttering in apps such as Gun Bros should be resolved
or significantly improved; some problems with memory handling
were introduced in 2.6.35.12 and are resolved in .13
Revision 1.3.0.9:
- The cause of super-lag has been found (Big thanks to twitch153 for helping me test)
- Introducing Universal builds! These universal builds are designed to be flashed on any
non-stock rom of the series marked (ie; Universal 2.3.3)
- Misc other tweaks to the kernel config that may result in an even smoother overall
experience
Revision 1.3.0.8a:
- Fix issue preventing USB debugging (and adb), and sdcard space from working
Revision 1.3.0.8:
- Updated to support the 2.3.4 rom update
- Lots of updates from upstream, including components needed to support
the forthcoming nexus s 4g (yes that means that I will be supporting the ns4g)
- Back to the 2.6.35.12 kernel base, the sdcard tweak has been scaled back
as it appears to have been causing excess lag
- BLN work for i9023 models from akent included (not tested), i9023 users may
find they can now use BLN
Revision 1.3.0.7:
- Revert back to 2.6.35.11 base until I can track down the cause of ridiculous lag in the .12 base
(Not that .11 was a bad performer by any means ;D)
- BFS builds updated to BFS401
- BFS users should find that they have regained their bootanimation
Revision 1.3.0.6:
- Voodoo driver updated to v8
- Custom voltage sysfs interface has changed,
the method used in 1.3.0.4 and 1.3.0.5 is not compatible.
See the guide in the 2nd post for details on the new method.
Revision 1.3.0.5:
- Raised max voltage cap by 50 mV for people who want to try raising the voltage a little bit on 1.4ghz
- More tweaks to try and address instances of "super-lag"
Revision 1.3.0.4:
- Corrected a bug that could cause a slightly higher voltage to be used at certain speeds (resulting in slightly faster battery drain)
- Added a sysfs interface for manipulating voltage levels at various speeds, see 2nd post for details
(read: this allows the possibility of custom under/over volting in realtime)
- Used a different build configuration that may address the occasional "super-lag" that appeared in 1.3.0.3
Revision 1.3.0.3:
- Update kernel base from 2.6.35.11 to 2.6.35.12
- Updated BFS version from BFS 363 to BFS 400 (BFS builds only)
- Raised default read-ahead value from 128 to 2048 (read: sd speed tweak built-in, scripts not necessary)
Revision 1.3.0.2:
- Updated Voodoo Sound driver to version 7
- Fixed a bug that made the sysfs file "scaling_available_freqs" not exist
Programs that must read this file for discovering/controlling available cpu speeds can now do so.
(This also means that CM7 users can set their cpu speeds from the cyanogenmod performance
settings instead of having to use SetCPU)
Revision 1.3.0.1:
- Add initial BLN support (Currently only functional on SAMOLED models [i9020])
Download the BLN control app from the market to use BLN functionality
Revision 1.3.0.0:
- More adjustments to the default colours to try and de-smurf the
previous adjusted defaults while still avoiding "Yellow tint shock"
- Voodoo sound updates (see github commit if you want more details)
- Fixed a bug that caused boot times to take significantly longer than necessary
Revision 1.2.9:
- Voodoo Sound v5 driver update
- Adjust default colours to avoid the initial "Yellow tint shock"
Revision 1.2.8:
- Voodoo Color gamma fix
Revision 1.2.7:
- Voodoo Color driver updates/fixes
Revision 1.2.6:
- Bring panel code up to date with official kernel
- Update Voodoo Color driver to v2
- Release initial cm7 2.3.3 compatible builds
Revision 1.2.5:
- Add 2.3.3 compatible builds
- Incorporate many updates from the newer 2.3.3 kernel sources,
including wifi driver updates, touchscreen updates, drivers for
future SLCD nexus-s variants, and more
(far too many bugfixes and updates to list, review the commit list on my github if you want details)
- Ext4 tweak should be working again in stock builds
Revision 1.2.4:
- Add NFS modules
- Make TUN built-in rather than modular (this may address issues some have had loading the driver)
- Add Voodoo Color
Revision 1.2.3:
- Update kernel base to 2.6.35.11
- Removed the ~56fps cap
- Conservative governor tweaked to perform better for users that choose to use it
- Greater rom compatiblity, particularly with roms that use specialized init scripts
Revision 1.2.2:
- 1.3ghz and 1.4ghz added to the frequency table for overclockers
- Default cpu speed on boot is 1000mhz, use a tool such as SetCPU to overclock
(No doubt I'll get some flack for this, but it's a very bad idea to boot into the max possible overclock when not all phones can tolerate it, so I consider it a necessary evil)
- Interactive Governor added, use a tool such as SetCPU to change to it if you want to try it out (Probably needs a bit of tuning to avoid annihilating battery, we shall see)
- CFS and BFS variants are now available
- Infused with the power of 1000 rabid naked bunnies
Revision 1.2.1:
- Ext4 hack should be working properly now
Revision 1.2:
- Fixed a condition where limiting max speed to 1000 would result in
potential underclocking to 800 (Thanks DebauchedSloth)
- Set hi-res timer to 1000hz
- Gave a little more power to the cpu at 1.2ghz, this may help those
having trouble running at 1.2 be more stable
- Integrated ext4 hack into the ramdisk builds
(ext4 hack is not technically a kernel issue but worth pointing out)
Revision 1.1:
- 1.2ghz overclock *really* works now -Thanks for the help Morfic-
- Cpu policy fix to avoid crashes with SetCPU and screen off profiles
(Courtesy of work by coolbho3000)
Revision 1.0:
- Initial release
- Add BFS scheduler
- Add 1.2ghz overclock
- Add BFQ
- Add Voodoo Sound driver
- Add CIFS support
- Add TUN support
- Update kernel base to 2.6.35.10
Custom Under/Over volting 101:
Code:
**As of 1.3.0.6 the method of custom voltage control has changed, read carefully!**
It is now possible for users to define custom levels of under/over
volting via a new interface in sysfs.
The interface file in sysfs can be found at
/sys/devices/system/cpu/cpu0/cpufreq/UV_mV_table
By default, the custom values are all zeroed out, so a
` cat /sys/devices/system/cpu/cpu0/cpufreq/UV_mV_table `
will show:
1400mhz: 1450 mV
1300mhz: 1400 mV
1200mhz: 1350 mV
1000mhz: 1250 mV
800mhz: 1200 mV
400mhz: 1050 mV
200mhz: 950 mV
100mhz: 950 mV
Modification of voltages is possible by echoing a string of 8 values
to the sysfs interface via the console, where the order of values
goes left to right from highest frequency affected to lowest.
To adjust the mV for a particular higher or lower than the default,
echo values divisible by 5 like in the following example from an adb shell (this is JUST an example, not guaranteed working values ;D):
` echo "1500 1400 1325 1275 1200 1050 900 850" > /sys/devices/system/cpu/cpu0/cpufreq/UV_mV_table `
Which has the following effect when examining UV_mV_table:
1400mhz: 1500 mV
1300mhz: 1400 mV
1200mhz: 1325 mV
1000mhz: 1275 mV
800mhz: 1200 mV
400mhz: 1050 mV
200mhz: 900 mV
100mhz: 850 mV
Rom developers, you can conceivably create custom scripts to
apply various under/over volt settings
For reference, these are the default voltages:
Default Frequency Voltage Table:
1400mhz: 1450 mV
1300mhz: 1400 mV
1200mhz: 1350 mV
1000mhz: 1250 mV
800mhz: 1200 mV
400mhz: 1050 mV
200mhz: 950 mV
100mhz: 950 mV
Additionally, there is currently a safety cap of 1600mV for max voltage,
setting a value higher than 1600mV will currently not have an effect greater than 1600mV.
(Read: You can set a value higher than 1600, but it will get dropped to 1600 behind the scenes)
This can be altered for future builds if I get feedback asking for it.
Backlight Dimmer:
Ezekeel said:
Based on the latest BLN version 9, I made some modifications to implement a backlight dimmer which does not need an external program (like cron) to trigger an off-switch.
To activate the dimmer, just echo the dim interval in ms (this is milliseconds; 1000ms = 1s) into /sys/class/misc/backlightnotification/in-kernel-dimmer. If you pass a value of 0, the dimmer will be deactivated.

FAQ:
Code:
Q: I'm getting a "Device or Kernel version not supported" error in Voodoo Control Plus!
A:The error is referring to the generic modules that voodoo control plus comes with to support
kernels that don't already have voodoo built-in (such as a completely stock kernel).
You can safely ignore this error, as voodoo is already built into the kernel.
Q: I'm getting SOD's (Sleep of Death) when undervolting!
A: You are probably undervolting too far
Q: OMG I'm getting a black screen (no boot animation) when booting a 2.3.3-based rom!
A: This tends to happen mostly on BFS builds, though it *can* occur on cfs builds (and even on the
stock kernel). The exact cause of this glitch is not known at this time, however, it is purely cosmetic.
You will notice that the bottom buttons are lit, and if you were to run adb logcat, you will see that the
phone is active. The phone is actually booting, just be patient.
Q: What are BFS and CFS?
A: They are task schedulers (they determine what processes get cpu time, how much, etc).
CFS (Completely Fair Scheduler) is the default scheduler in the official mainline kernel. It's a tried, tested, stable scheduler.
BFS (Brain **** Scheduler) is a third party scheduler written by Con Kolivas that must be patched into the kernel, and replaces the CFS scheduler. It tends to be faster in certain tasks, and is usually pretty stable, but sometimes there can be performance quirks.

Is using setCPU advised?

SetCPU is not necessary.
You're free to use it of course, just remember that the NS idles at 800mhz, so if you use a screen off profile, take that into account.

Koush's anykernel can serve that purpose. It splits out the ramdisk from the current boot on the phone and combines it with the zImage of the new kernel (meaning no having to manually repack ramdisks to make various rom-compatible builds), then flashes the new boot image.
Once I have it playing nice with the NS I'll be able to post universal builds. One of the many things on my todo list ;D
Nice. Loved your work on my evo and stoked to try it here. More kernel devs means more choice and hopefully a richer collaborative spirit

- 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

After long become a viewer, learning, and debugging. I'm proud introduce :
SwiftExtreme Kernel for MCR/Stock - FROYO - ABANDON
Click to expand...
Click to collapse
Version Dated 06-September-2011 is the latest, no bugfixing, no deployment again, if you find bugs, sorry, I can't help you again, I'm already try to fix all the errors that I find, see you again when LG release new kernel with Gingerbread hopefully
This kernel is heavy with patches and tuning, so it can give better performance with STOCK/MCR ROM with less power drain. It has many patches that included, maybe I'll miss some credits..
But for most of the time this kernel credits to:
Cpasjuste for awesome work OC/UV mechanism
Morfic for awesome patches related with LG star
Faux123 for awesome patches related with LG G2x/Motorola Atrix
Ardatdat for awesome patches with A500
Kernel arm mailing list for awesome patches
[email protected] for cool RAMDISK image
Imperticus for cool kernel, I learn a lot from what his doing
supercurio for voodoo sound patches
[email protected] for screenstate script
Djdroid ROM for led script
This is the latest version of SwiftExtreme-Final:
-Based on Kernel 2.6.32.43
-OC Upto 1.4Ghz
-Redesign cpasjuste OC mechanism, so, now possible to make version upto 1.2Ghz if anyone needed
-ZRAM Builtin SWAP(check for zramscript in init.d, customize if you feel it doesn't work correctly with your need)
-Remove screenstate script in init.d from previous kernel, I don't see benefit of this script
-AVP overclock, smooth audio/video processing
-Remove 3D overclock, it doesn't give 3D performance a lot, only gives battery drain
-Add zipalign script to kernel, to make your stock ROM smooth, better memory consumption and feel faster
-Voodoo V1 sound driver, if you get choppy sound, try removing your voodoo control application, and try again without those voodoo control application, from what I see, this voodoo control application doesn't work very well with voodoo sound driver in this kernel. But sometimes, reinstall voodoo control application can solve choppy sound output.
-Use SLQB as SLAB memory allocator
-Replace BFQ with simple I/O kernel I/O scheduler, really fast...
-Patched with optimized ARM RWSEM to better performance
-Use optimized kernel memcpy
-Patch with sometimes CPU forget second core clock
-Patch with add memory contiguous memory allocator, from information, it should free some memory after kernel loading
-Patch with autogroup
-Patch with tinyJRCU for better performance
-Patch with 50% EXT4 regression, it should gives better performance with EXT4 filesystem
-And other small patch that I don't remember correctly
I'm sorry if I still not perfect for kernel builder, I just want to share what I've done

This kernel only work for FROYO based, not working with Gingerbread, the reason not compatible with Gingerbread because ramdisk incompatible between Gingerbread based, for example I make compatible with modaco kernel GR2, but in other gingerbread, it run, but WIFI doesn't work, so, to prevent problem, I don't consider Gingerbread release until LG release official
I'm included stock lockscreen if anyone from 0725 based stock ROM need it, it can wakeup and fast unlock compared with those sluggish LG lockscreen, replace in /system/framework, don't forget to change the permission like the old one...

1. You use another script that undervolt 1ghz. Or
2. Your P990 doesn't support boot @ 1Ghz with 990mV.

hey fajarep
does your kernel require voodoo control plus to enable voodoo sound driver?
i can't enable it in the app.

I also don't understading what is happening.
i'm using the Modaco FR19 without any modification.
other users doesnt have problem with.
who knows =/
*** THIS KERNEL ONLY SUPPORTS SAMSUNG TW JB 4.1.2 ROMs (STOCK and CUSTOM). DOES NOT WORK IN CM or AOSP!!! ***
*** The Kernel is Safe (MMC_CAP_ERASE disabled) and the included PhilZ Recovery uses delete recursive and avoids brickbug ***
*** Stiil, I take no responsibility if the provided KERNELs causes any problem to your phone, you are warned! ***
Hello Friends,
I am no developer, just an Android lover. I share with you my first custom kernel for Note N7000 JB building from sources. It was made mainly for my hobby and my own needs, but hopefully can be useful to other members.
Forest-HelloWorld-Make-II kernel
As the name suggested, it is essentially a continuity of the C.O.H HelloWorld kernel.
FEATURES:
Features added by me:
- Implement r3p1 GPU driver to JB4.1.2 (from V2.0.0 (Credits and thanks to @GeeckoDev for this excellent work)
- OC OLED panel refresh rate to 60 (from V1.9.1)
- Remake GPU to 4 steps (V_1.9.0) (Very capable for gaming why maintain good battery life)
- Compile using Linaro toolchain 4.7.4.(12.2013) (V1.9.0) (it feels silky smooth)
- Update recovery to PhilZ Touch 5! You have a more beautiful and intuitive GUI. (from V1.8.2)
- Use LZMA compression (from V1.8.2).
- BLN support (only for V1.7.3)
- Enable OC CPU to 1600 (from V1.6.4 for OC CPU versions)
- Exfat native support (Now you can enjoy unlimited file size and fast speed on ext-sdcard)
- Kernel linux version 3.0.31, build using Ubuntu 13.10
- Toolchains: CodeSourcery G++
- Some optimization of the config file
- Su binary is updated to the latest version.
- Made three versions: 1) With OC of both CPU and GPU 2) With stock CPU and OC GPU and 3) With stock CPU and GPU.
Features benefited from C.O.H kernel:
- CPU Hotplug support from Speedmod kernel (only 1 core when not in load, battery friendly)
- Disabled logcat and dmesg and unnecessary Samsung debugging.
- UV capability.
- Increased Touchscreen sensitivity even when charging (Best touch response to date in Note).
- FSYNC Control 1 (from Ezekeel's GLaDOS kernel for Nexus).
- Tweak GPU in GPU OC version: 133, 267, 400 MHz (3 steps),
- Many cpu governors and schedullers: Defaults are Hyper-Row now (You can also tried noop-pegasusq as recommended by C.O.H)
- Fix for wifi drain on standby (disabled all multicast).
- Speedmod K5-3 fixes included
- Other features are the same as in c.o.h’s HelloWorld Kernel.
-------------------------------
HOW TO ENABLE LOGCAT (Only for V1.6.4 and lower!) .Credits to @hardcore:
If you want to re-enable logcat for whatever reason, do this:
adb shell
su
mount -o remount,rw /system
echo ANDROIDLOGGER >> /system/etc/tweaks.conf
mount -o remount,ro /system
exit
Reboot android system. Then can take logcat as you wish!
--------------------------------
The kernel is very smooth, stable and battery friendly.
CHANGELOGS:
HelloWorld-Make-II-V201-P:.
- OC-CPU
- Stock GPU
- Compile using uber toolchain 4.7
Excellent speed and good battery life. This is my current most favorite one.
HelloWorld-Make-II-V2.0.1:.
- Stock GPU and CPU.
- Compile using uber toolchain 4.7
Excellent speed and good battery life. This is one of my favorites.
- Change logs of other versions: see links in download section!
HelloWorld-Make-II-V1.9.0:.
- Remake GPU steps
+ Forest_HelloWorld-Make-II_V1.9.0_AM1 which is more agressive with GPU steps: 133-267-333-400
+ Forest_HelloWorld-Make-II_V1.9.0_GL2 which is more gracious, gentle with GPU steps: 133-200-267-333
- Disable UV interface.
HelloWorld-Make-II-V1.8.2:.
- Update Philz recovery to PhilZ Touch 5.
- Putting back logger module with option to enable it (for those who want to get logcat)
- Use LZMA compression
- Set default Governor to Pegasusq
- Update su and SuperUser to V1.94
- BLN dropped!
Bugs:
- The OC-CPU version has stock video bug the same as V1.6.4. Use MX video play instead!
- Recovery only accept to format internal and external sdcard using default format.
HelloWorld-Make-II-V1.7.3:.
- BLN support added.
HelloWorld-Make-II-V1.6.4:.
- OC CPU to 1600 (you can enable it using Nofrills or SetCPU...)
- UV 25mv for each steps, for balance performance and battery life.
- Include VR I/O scheduler, leave out Deadline
- Tweak thermal threshold (first level from 64 to 70, second level threshold keep the same).
Significant improvement for heavy games: I can play my favorite Let's Golf 3 super smooth now.
Bugs: stock video only play from gallery. Use MX video which is much better, btw.
HelloWorld-Make-II-V1.5.5:.
- Leave out some Governors, keep only 5: Hyper, Performance, Ondemand, Pegasusq, and SmartassV2.
- Leave out I/O Schedulers, keep only 5: Row, Sio, Noop, Cfq and Deadline.
- Padding zImage to the full size of the Kernel partition, 838808 bytes (Thanks to the trick by Chenglu and PhilZ!) this should help make the flash of kernel always clean.
- other minor tweaks
The new version is leaner, lighter. Should help improve performance and battery life!
For those who is on V1.4.5 it is recommended that you move to V1.5.5

Thanks NokiaModeln91!
It is harder than I thought building a custom kernel from source, and unpacking Initramfs from zImage. I am very happy I made it.
Try it our! I find it really good indeed!
Anyone flash this kernel im on sweetrom 10.5 with speedmod k5

Great work I can't try it atm. as I am on a stable OmniROM which I have had for a month but once this breaks I will give it a go
Are there any plans to add more tweaks?

My bad . Thanks for pointing that out. Links are corrected now.
forest1971, quick question. How can i edit mount points ? Example, /system is mounted in /dev/whatevah and i want to change that. Is it possible ?
You can find mount points in the guide in my signature.
Btw, the question is not relevant in this thread.

Great work i flashed last night stock gpu one running smooth now lets see how much screen on time on this kernel i will get
With speedmod k5-5 i m getin 5 hours with wifi on
---------- Post added at 04:30 AM ---------- Previous post was at 04:01 AM ----------
I m getin 30 min screen on time for 15 percent battery level cost
This mean maximum i can get 4 hours screen on time
Please make speed mod k5-5 make 2
With updated recovery and with cpu governers and leave all same as it is
This will be a perfect kernel for those people who wna spend life little bit more with note without charge

Speedmod k5-5 seems to be the benchmark for performance and battery life. I suspect too many governers and schedullers may harm the battery life. I will make a new ones with only few of them.
Still, kernel takes time to settle down with rom. So it is still too early to judge. Cheers.

this kernel support crt animation and boot animation? thanks
via MyOwnName™ device
Boot animation, yes. CTR animation, not tried yes. You may want to try in your rom and lets know. Tks.
