Just a statement regarding kernel source: The Kernel Source is of course covered under GPL version 2. Free software does NOT mean no work or time was spent working on it. I have donated a large sum of my free time to hack this kernel. If you use my modified kernel source in parts or in its entirety, I kindly ask you mention its origins and to send me a github pull request or PM whenever you find bugs or think you can help improve my kernel hack further. This way the entire community will truly benefit from the spirit of open source. Thank you !

Hi RootzWiki members and fellow Samsung users:

This is my fourteenth kernel hack. I want to thank b16, and the entire RootzWiki Staff, and several others I cannot recall for inspiring me to venture into this unfamiliar territory for me.

What is a Kernel? The Kernel is the Foundation in which everything else builds upon in any software system.
[Car Analogy]: Kernel is like the Engine, Electrical system and the Transmission to a car. The Library, Framework and the Apps [AKA ROM] are the body frame and the rest of the Car.

THIS KERNEL is BASED ON Google Source Code. So it is COMPATIBLE WITH ALL AOSP ICS 4.0.1, 4.0.2 or 4.0.3 Builds.

DO NOT use any task killers, they DO NOT improve performance nor battery life. They INTERFERE with your phone's stability (more crashes) and App compatibilities (Forced Close).

Kernel Features:

So what type of kernel is this? Well, this kernel is based on Linux 3.0.y (says so from the version string) but it's really a hybrid between Linux 3.0.y and Linux 3.3+ due to many features introduced from Linux 3.3+ (for specific details on technologies, see 2nd post below!)

Here's a step by step instruction to install this kernel:

1. download the above file (via phone directly or to a PC)
2. copy the downloaded zip file to /sdcard/download/
3. Open ROM Manager and select "Reboot into Recovery" and select "OK"
4. Once in recovery, select "wipe cache partition", select "Yes", then select "advanced", then select "Wipe Dalvik Cache", then select "Yes" again. Once finished, click the back button to go back to the main recovery menu. On that menu, select "Install Zip From SDCad", then select "Choose zip from SDCard", then go to /sdcard/download and select the downloaded zip file and let it run its script.
5. Once the script is done, select "reboot system now"

Note: After FLASHING, the first reboot may take longer than usual, please be patient... After the first reboot, it may lag during initial load (let everything finish loading). Once everything is loaded and phone is ready for use, reboot the phone a 2nd time and the lag will be gone and everything should be silky smooth...

[ Advanced Users: ]

[ Optional: ]

If you encountered any funny / weird / strange issues coming from other than 100% pure stock ROMs or my kernels, the following "Reset Kernel" will restore the kernel to its Original Stock Settings.

Version 022 (JB)

revert 1 mainline patch for better I/O performance
add GPU governor select:

default GPU governor: "ondemand" the other is "performance" (full CLOCK no scaling)

to change GPU governor behavior:

echo 0 > /sys/kernel/pvr_simple_gov/pvr_simple_governor (for performance)
echo 1 > /sys/kernel/pvr_simple_gov/pvr_simple_governor (for ondemand, default setting)

Tweaked Intellidemand for better UI performance
Updated PowerHAL from 30k/300k to 50k/500k sampling rates (screen on/off)
Tweaked Intellidemand for better battery performance

Added Intellidemand PowerHAL (Courtesy of Termleech. Thank you very much man!)
(no kernel changes, simply a lib update for the ROM)
patched Intellidemand to 3.2 with bug fixes
Introducing Intellidemand 3.1

(See below for Intellidemand logic)

cpufreq/cpufreq_intellidemand: intellidemand cpufreq governor (version 3.1)

Intellidemand is inspired by ondemand governor. Its main features are:

- auto cpu hotplugging based on runnable thread average calculations
- detection of browsing mode (long screen on activities with moderate run
queue depth =< 38 )
- limit max frequencies when in browsing mode to conserve battery for long
duration tasks

Browsing State Determination:
1- Browsing state is enabled as power-on default. Browsing state is disabled
when run queue depth is > 38 for 2 consecutive samples
(very high instantaneous spikes)

Browsing State Limit Max Freq Logic (sliding window algorithm):
1- While Screen is ON > 3 min, and average load of the CPU is < 35%, then
CPU Max frequencies will remain power-on default
2- While Screen is On, if average CPU load > 35%, both CPUs max frequencies
will be limited to a lower user configurable max value
3- While Screen is On, After both CPUs' Max is limited to lowered max, when
the average CPU load has dropped down to less than < 25%, then both CPUs
Max freq will be restored to back to power-on default

Runnable Thread Auto-hotplug (fast hotplug / slow unplug algorithm):
1- When average number of running thread is < threshold, 2nd cpu will be
unplugged.
2- When > threshold, 2nd cpu will be hotplugged.
3- The logic applies a fast hotplug and slow unplug algorithm so 2nd core
will stay enabled longer to help deal with performance spikes

changes from Ver 3.0 -> Ver 3.1:
- add run queue persistence to better determine browsing state
changes from Ver 2.0 -> Ver 3.0:
- remove GPU Busy dependency for browsing state detection (this will make
the governor more portable to other platforms without specific GPU
architecture knowledge)

dependencies:
-- Qualcomm's run queue average logic (SOC independent logic)
-- TI's runnable thread average logic (SOC independent logic)

adapted for OMAP2 platform

DUE TO MY EXTREMELY BUSY SCHEDULE BOTH @ WORK AND @ HOME, I WILL ONLY MAKE MAJOR ANNOUNCEMENTS ONCE PER WEEK
Open Beta may not be stable and may cause issues with your phone!

By loading open beta you have agreed to:

1. To report all random reboots with associated /proc/last_kmsg
2. To provide feedback on errors or bugs with detail phone information such as ROM, kernel version, and apps
3. Participate in Forum discussions for the beta software with others without FLAMING each other or post useless information such as:
a) Phone doesn't boot (without providing any additional information, ROM versions etc)

phone is too hot (without providing any additional information, ie OC freq, UV etc)

The Open Beta system is designed to have the community help each other and the developers. This way, all potential bugs are flushed out so the final released version will be stable and error free. The more actively you participate in Beta Testing the better the final product will be (you are really helping yourself to create a better community software).

If you do NOT agree with the statements above, DO NOT load my Open Beta software.

Amazing mate! You can do the same thread in LTE section, because both devices use the same kernel.

Glad to have you on board the GN dev't. faux123! The more devs we have, the more options for the community! I used to rock your ROM on the G2x.

You might want to clear out your OP.

Cleancache -> don't need that shit and causes extra CPU/IO overhead

jRCU -> Sorry there is no jRCU for 3.x as of yet, me and Joe Korty are working on it
Fast NO HZ RCU - > Can't use that because in order to compile this kernel you need to have CONFIG_PREEMPTION activated
Smartassv2 -> I'm sorry, but it sucks
Interactive -> Same thing
BFS -> Doesn't boot. On the Nexus S caused a lot of issues to stock rom users because sdcard wasn't mounted etc etc
BFQ -> Seriously? Comon...

Have fun.

Perhaps you need to go back to XDA with that attitude. That post was useless and did nothing for the developer community. Or at least give a little better explanation that "it sucks."

franciscofranco · Dec 10, 2011

I told him my opinions about his OP items, I don't see a problem with it, it was constructive criticism.

b16 · Dec 10, 2011

Back on topic please, thanks! Keep up good work Faux!

Ezekeel · Dec 11, 2011

Franco often uses a quite colloquial language style when discussion kernel tweaks. I am pretty sure he does not mean to insult anyone. And while the form of his feedback might be lacking, I have to agree with the central statement that some of the listed features do not make much sense for the GN or are in general not worth adding.

Faux has a professional attitude and I am pretty sure he values any feedback including criticism from other devs since this helps him improving his kernel(s).

franciscofranco · Dec 11, 2011

Thank you Eze.

I don't mean to insult anyone, this is how I talk and I wanted to help Faux with a little of my knowledge as I'm pretty sure he values other peoples feedback.

I can provide a full feedback on all of those items if Faux desires, but I really didn't like seeing an OP full of supposed "features" that either can't be implemented, or that simply have been proven to completely suck. Like I said I'll be more than happy to provide my feedback and knowledge if Faux so desires.

faux123 · Dec 11, 2011

Version 002 is out! History in 2nd post!

Stea1thmode · Dec 11, 2011

Running this on RHD, performance is very consistent with this kernel, decent benchmark results, everything is smooth and lag free even after 5 hours of sleep.Well done mate, my favorite kernel so far. Nothing else to report.

faux123 · Dec 11, 2011

Updated yet again... 003 is out! Undervolt and GPU OC now added.

inffy · Dec 11, 2011

Damn, you're fast

Thank you, will test this tonight or tomorrow =)

Stea1thmode · Dec 11, 2011

Oh my gosh, you're killing me

Thanks.

skyhigh2004 · Dec 11, 2011

Is the gpu overclock implemented by default? Also is this UV at all by default?

faux123 · Dec 11, 2011

GPU OC is on by default. UV capability is there but all the voltages are stock values.

termleech · Dec 11, 2011

I know its still early but can anyone comment on battery life? Also not being a kernel dev myself can someone comment on the difference between this kernel and Franco? I'm trying to figure out which to use for best performance and battery life.

Sent from my Galaxy Nexus using Tapatalk

Stea1thmode · Dec 11, 2011

I've not had the kernels on long enough to monitor overnight discharge since Faux is churning them out rapidly. LOL
On a serous note, IMO Franco's previous kernel gave me stutter and some lag( I can't comment one his current one though), this one seems to be fast, very stable and buttery smooth. Performance wise, for me this one hits the sweet spot.

I've not noticed any glitches yet.

Best thing is to try them both, I like stability some prefer performance.

edit: Oh my, GPU OC is noticeable!

balenax · Dec 11, 2011

downloading it now! thanks.

sim_jim · Dec 11, 2011

Thanks for the kernel and ur hard work ..

testing it now for 3 hours so far everything is running fast and smooth .. GREAT JOB

joackie27 · Dec 11, 2011

Has anyone tested the problem wherein when you power off your phone while charging, the phone locks up (power button doesn't work and the battery charging icon on the screen gets stuck) and only a battery pull resolves it?

faux123 · Dec 11, 2011

Yeah, this is a known issue. I am not sure what's the cause of this. Will look into this.

kara mustafa · Dec 11, 2011

Hi,
are you able to add USB HOST in kernel?

BTW, great kernel. thanks.

skyhigh2004 · Dec 12, 2011

Just an update, been testing this kernel all day and I must say its very fast and smooth. I also have to say my chip must love the UV because I've been testing it out and have been successfully running at

1200mhz:1175mv
920mhz:1050mv
700mhz:950mv
350mhz: 825mv

So far battery has been stellar. I'm gonna keep pressing the limits of my cpu and see where I get

. Also faux, is there a recommended volt you don't go under for a certain clock? Like does the chip have a minimum voltage?

Edit: this is the lowest I will go as I'm assuming this is approaching what would be considered safe limits. Runs great. Hopefully setcpu is reporting and controlling this correctly. Will report back with battery findings tomorrow night.

tried to undervolt, using :

did a couple of tests, cf bench, some quadrant, linpack, setcpu stress test, all went fine, played fiendrunners hd for about 30 minutes, no problem. but when i try to power of the phone it gets stuck displaying : powenring off and i need to remove the battery. upped the 350 voltage to 900, same story... where do you think i should up the voltage more so i don't have to remove the battery everytime i need to reboot?

thanks.

inffy · Dec 12, 2011

The problem with the phone stucking on reboot / shutdown, when it's connected to charger seems to be a CWM recovery issue.

balenax · Dec 12, 2011

if you were talking to me : i don't have the phone hooked to the charger or pc. will keep trying some more settings though

, would love a bit of uv

kfjunky · Dec 12, 2011

Running 3.0.3 since this morning for a couple of hours.

UV at,

1200:1175
920:1100
700:950
350:850

Don't want to push too hard for now on the voltages.
Smooth UI and no other issues with the above settings so far.

Battery life is awsome, with the other 2 popular custom kernels, I used to lose 2% per hour on standby
with no auto syncs, but after flashing this kernel, I have only lost 1% in 2 hours!
No battery calibration whatsoever done.

My Rom is Revolution 3.1.2, and I love this combination since my Sensation days.

Cheers.
