[Kernel KH3&KJ3]Red Nebula [sched tweaks, vm tweaks, ondemand tweaks][zipalign added]

[Kernel KH3&KJ3]Red Nebula [sched tweaks, vm tweaks, ondemand tweaks][zipalign added]
This kernel does not support lagfix(ext4) at least not till I finish work on cwm and build in universal lagfix
Added Zipalign version (file ends in ZA)
Here it is Red Nebula v1.2 (kh3 and kj3 versions now). Its modified from boogs kernel (thank you for the use of your kernel as the base boog without it this wouldn't have been possible) with a lot tweaked and added. Quadrant for me runs around 2000 with it. I recommend cf bench by chainfire or antutu for benchmarking instead though as they have a lot more tests that matter in the android world and as we all know Quadrant means jack anyways. UI is extremely smooth and lag free and system is always extremely responsive.
Update:1.2 is released (pulled 1.0 and 1.1 all together) it includes a few more tweaks for responsiveness and helps out cf bench scores overall and lowers quadrant again, wtf quadrant. ;p
Remember this kernel is tweaked to give a highly responsive lag free device it is not built to get crazy high test scores as most of the tweaks I made improve overall i/o performance, disk throughput, java efficiency, and keep as much memory free as possible without going overboard killing everything in the background, a lot of the tweaks also will help battery life to some extent.
Also please don't request a lag fix version, I built one and it really didn't make much, if any, difference and that's with over 150 apps on my phone. Something about GB on the captivate seems to negate the effects lagfix normally has on performance so I left it out to simplify things and cut down on space in the kernel to save for future tweaks.
##List of mods(Updated)##
#tweaks to lmk keeps mem use down without going overboard
#aggressive version should keep mem free around at least 60mb
#swappiness is tweaked for speed when switching between open apps
#vfs_cache_pressure tweaks help improve overall performance but may require
a reboot every other day in the standard version to keep things snappy aggressive version shouldn't suffer as from this side effect as badly
#various other kernel scheduler tweaks
#tweaks to cpu scheduler(designed for on demand governor only)
#tcp/ip modified for speed and security
#other vm property tweaks improve speed and batterylife
#custom boot animation support for sanim.zip (KH3 still has no boot anim, sorry guys this thing is killing me trying to get working.)
#internal memory (SD) tweaks to reduce disk overhead and increase throughput
#added a new zipalign version of the kernel (the ones that have ZA at the end of the name it will zipalign all apks /system and /data that are not already aligned. just gives an extra little boost to performance.
note: I'm having problems getting custom bootanims working still for kh3, it won't show one so dont freak if you don't see anything after the att screen. It also helps boot time slightly if enough request is made I will post another version with the bootanimation re-enabled to the normal galaxy s boot.
##need to fix##
just bootanim support for now
##fixed in kj3 kh3 fix coming once I can figure out kh3's problem with me##
/\/\Thanks to Kyuta/\/\
##Installation Notes##
To begin as always I am not responsible for any damage to your device or loss of data damage.
Make sure you disable lagfix if it is enabled before installation of my kernel it absolutely doesn't support lagfix and I don't want anyone ended up with a soft or hard brick for trying to flash over a lagfixed device.
Installation is straight forward download the Red Nebula zip attached below and flash through cwm as normal. The only thing to keep in mind is this will wipe all you init.d scripts but it does back them up to /sdcard/initd_backups in the new versions just in case you want to try re-adding any later.
I set it to remove them to prevent scripts already in place from messing with those included with the kernel. Also the kernel doesn't work for nandroid backups as with pretty much all gb kernels so far so please don't try unless you are't worried about bricking.
Also the installation does clear caches for you during installation but feel free to do it anyways afterwords if you want.
note about initial boot up lag: After boot when the system is loading your homescreens you will most likely encounter a small lag at first then everything should come up very fast after a second or two. This is due to the read ahead buffer tweaks I made. They are loading up more information initially and this is what is causing it. The reason for me going slightly more aggressive than the norm is after initial boot up overall read/write rates are dramatically improved over other values I've tried and it makes for a much snappier feel overall, especially when opening gallery, accessing large music libraries and opening file managers.
Feel free to ask questions and leave feed back.
##Credits##
Boog-for the use of his kernel as a base
Kyuta-for help with getting bootanims fixed
ddoubt-for pointing out I forgot to fix the symlink in my
updater script for bootanimtion
All the people at IBM making manual pages
All the people who have made pages/manuals about the linux kernel & tweaking it
Without the above none of this would have been possible.
##side note to other devs##
you may include my tweaks and values in your kernels with credit given, I've spent countless hours researching and testing to get this project to where it is now. About 30-40% of the values used have been previously used by many others before but the rest I found researching manual/reference pages and some I found to work best through trial and error. The scripts except 99completed and the bootanimation script are my own work and while most are basic they are mine so please don't include them in tweak packs, kernels, and rom & kernel packages without permission.
##--updated links for fix to init.d backup scritpt and error in updater-scritpt!!--##

Wow, some body use stock please test this kernel. I will try when I back to stock ^^!

Heres a few test screens. Oh and I forgot to mention ram usually runs between 158mb-220mb. It pretty much has the zram tweaks but modified to values I decided on after reading dozens of linux kernel pages. Some values you might find in other scripts but most arent.
Its also optimized for the on demand cpu governor and I recommend overclocking with tegrak to get the most out of my tweaks.

The GB bootanimation binary supports sanim.zip and not bootanimation.zip Not sure if that helps.

smooth.... flashed using SGS Kernal Flasher after turning off Lagfix. So far so good!

Congrats on ur kernel Jsmokey Nice to see more guys step up in the dev, specially when others are leaving due to phone upgrades. I personally don't use ur kernel yet (i9k user so far) but it's great for us cappy users to have more choises to pick from, so I *****slapped ur thxbutton

Tried that too when I was working on it still no luck. Only thing I could get to play them was the script from the old onix froyo kernel but the anim would just keep playing and according to logcat the ui was loaded completely.
And thanks everyone. I'm glad you like it. I spent alot of time researching linux kernel manual pages to find the best combinations of tweaks to put together and spent many late nights debugging,

Thanks and I plan on working with them I just started this project weeks ago as a rom/kernel package but they both were taking up so much time I decided to split the kernel off and get it out there.
As soon as I finish up my rom I'm going to work on something for the newest leaks.

I actually have kj3 decompiled on my pc so if I have time I might go ahead and whip something up tonight if you want to test for me since I haven't started work on a kj3 rom yet and work on my kh3 rom doesn't leave much time for me to test others and let me know how it works.

Of course, I hate to give an eta but i'd say around a week and half and I should have pretty much everything wrapped up. Its been in the works since kh3 came out but I've spent a ton of time testing tweaks on it and the theme.
I posted a couple teasers of custom buttons and my battery gauge in the captivate themes post your homescreen thread if you want to check it out. I've been running it for weeks now and a few close friends have been lucky enough for me to put it on their cappy's for em.
Same as with the kernel ill be moving everything to a kj3 base as soon as the kh3 version is done.
Edit: I wanted to mention that I will be updating the first post to be a little more in depth of what the values and tweaks really do. Only reason I haven't is its alot of typing to really explain things properly and I hopefully should have some more tweaks ready in the coming weeks as I dig more into how the linux kernel handles things. I've came along way in understanding how the kernel works in the past few weeks but I still have mountains of information to go through.

Ok add the following to the end of your init.rc file and see if it helps with the sanim.zip.
Code:
on property:sys.boot_completed=1
stop samsungani

Thanks kyuta I'll give that a try a little later and see what happens. I might just switch back to the old onix script and give it a try since its the only thing i could get to play the animations at all. I'm sure that will work though with a little tweaking to fit with the set up i used with the onix bootanim script.
Also this goes out to everyone I got kj3 all compiled just waiting on xpackage to let me know if its booting or not and I'll post it up for everyone, or if anyone else running kj3 that can flash asap and let me know if it boots or not is interested just let me know and I'll pm you the link to get it.

KH3 gave me fits on getting boot animation to work correctly. Just finally had to give it a timelimit eg: sleep 20 then kill it. The leaks after kh3 work better.
Also, the newer kernels will run on kh3, and vise versa
Makes for easy testing, flash it, not good? flash back.

I kind of figured it was a kh3 problem with the bootanims thanks for the info I'll also give that a try after I get done with all the kernel sched tweaks i'm finishing testing and researching. Next update should be about as responsive as it gets, I don't think there's gonna be much to tweak left after I'm done, and it should greatly improve on i/o rates overall even more than the first release.
Sweet, wasn't sure how things would go flashing the newer kernel leaks over kh3 so i hadn't tried it so I'll go ahead and give it a flash then and see what happens.
Update
flashes and boots fine but it still loops the anim non stop on kj3 and i left it exactly as you set it up for the bootanim boog. I swear this thing is just out to drive me completely insane! I'm gonna try a couple things and see how it goes and I'll post back asap.
update again
OMFG I love you kyuta that worked perfectly!!!! It finally stops when its supposed to lol.
I'll get it uploaded in a few when i get the last few things checked out and make sure all my tweaks are being applied properly.

Check OP for link to KJ3 Kernel! And to Kyuta and Boog I can't thank you guys enough for the help you guys are life savers.

KJ3 Kernel
I backed up the init.d file with root explorer (etc>init.d) and flashed through CWM. No problems. My boot animation worked (sanim.zip).
Quick run through several programs and long press keys working, BT working, GPS working (LOL, at as well as it has at 15ft accuracy).
So far all is good. I will run it tomorrow to see how is does for battery.
I am also running Illuminance 1.1 for the ROM.
CWM version is v4.0.1.5 with the kernel.
Boot scans seem faster.
I know signal is the modem but I am getting -71dBm 20 asu with the KE3 modem and Red Nebula kernel. It is 0130 here in Norfolk but that is the best signal I have gotten.

Glad to hear it and as DDNV pointed out at first things will seem a little laggy at boot and I believe this is mainly due to increased read ahead buffers, which would cause sort of a momentary pause since they take a bit more time to fill then the default but loads very fast after that initial stutter since its loading a lot more info at once, 2048k compared to 128k default. I ran alot of sdcard speed tests with different settings and this seems to be the best balance between high read/write rates and initial system start up lag.
In the tests I ran it was like night and day in read/write speed compared to other values I tried. Also in my gallery I have well over 1000 images icons, photos, screenshots, etc and with the buffer tweaks it loads all of them almost instantly when I open it and it use to take between 10-20 seconds with default buffers. I will add this to op so people arent thinking its just lagging for no good reason at start up.

[Arrows - Guide] Best Aosp GB & ICS Roms [Updated - 1/22/12]

Feel Free to post and give feedback ^_^
Also feel free to Vote the thread ^_^
Q&A is in Post 2
_____________________________________
Hi Everyone, Arrow here and this is my guide to find what is the best aosp setup for your evo or android. It is true when people say "every phone is different." However there is an average of people that get similar results. At the moment people have different interest such as some people want performance and some want to improve their battery life. Of course certain people want both but only some get both.
*Remember what i put here is an average and may be different on your evo*
AOSP GB ROM'S: Ok so to start off, these are aosp roms still being updated as of now.
CyanogenMod 7 (CM7) - The most famous aosp rom out there, all or almost all other aosp roms are based off of this rom. This rom has a stable rom and experimental nightly builds. Anyone will tell you that you can't go wrong by choosing this rom. and believe me you will enjoy it.
CyanogenMod 7 Thread
Miui - This rom has the longest battery life and is very customizable. This rom is based off of CM7 and is an excelent rom. However unlike CM7 this rom does not have 4g so if you are willing to sacrifice 4g then believe me this is your rom.
Miui Thread
Gingerbread Evo Deck - Ok so although CM7 is amazing decks gb rom has said to be the exact same thing but giving off better battery life. other then that it is pretty much the same thing with some minor tweaks and some bloat ware removed.
Gingerbread-Evo-Deck's Thread
Xplod E4G - Team Nocturnal designed this rom and it is pretty much CM7 with the Sony Launcher + their apps. This rom will give your phone a nice cool feel that other people don't have. If you like a lot of eye candy then get this rom because it is CM7 just with a different look and feel.
Team Nocturnals Xplod E4G RLS1.2
teh roxxorz said:
using Xplod: there's a 50/50 chance the new tiamat kernels [4.0.7+] may not boot, in that case, they should use 3.3.7.
Click to expand...
Click to collapse
ICS(mod7) - Team Blaze designed this rom and you can consider this rom like Xplod E4G, a rom just like CM7 with some minor tweaks but with a different look and feel. None the less this rom has something very special this is the closest rom to being like ICS (Ice Cream Sandwich). I 100% support this rom because they are doing the best they can to make this rom look and run as smooth as ICS. so if you want to look like your ahead of the game definitely get this rom.
ICS(mod7) Thread
AOSP GB Kernels: These are three kernels that i know of, if you know of more please let me know and i will add them.
Tiamat 4.1.0 - This is the latest kernel made by Tiamat and this is the only aosp kernel still being updated. This kernel on average gives people great performance but lacks on battery life. The main Governor for this kernel is SmartassV2 which is a balanced governor, good to turn on your phone and good to use on a normal day to day bases. For this kernel i do recommend using this governor. It does have SBC and Non-SBC kernels. *Side Note* (Some people say Tiamat 3.3.7 works better for them and is also known as the LEE Kernel because it was awesome like Bruce Lee and looks like Lee backwards [337])
Tiamat Website I also put the Zips in the Attachment (At The Bottom)
Savaged-Zen - This kernel is no longer being updated, however it is still amazing this kernel seems to be Tiamat's competition. Where Tiamat lacks on battery Savaged-Zen does not. However it's performance is not as good as Tiamat. This Kernel comes in two version BFS (Brain F***ed Scheduler) and CFS (Completely Fair Scheduler). BFS is said to give better performance and CFS is the normal kernel. This kernel only comes with SBC however you may download "SVZ Manager" which will allow you to turn SBC on or off. The main governor for this kernel i believe is on demand However i use smartass and a lot of people us InteractiveX.
Savaged-Zen CFS sbc I also put the Zips in the Attachment (At The Bottom)
Savaged-Zen BFS sbc in attachments (At The Bottom)
SVZ Manager I also put the Zips in the Attachment (At The Bottom)
GoDm0de - This Kernel was made by toastcfh and is no longer being updated. It is non-sbc and in my opinion definitely the best non-sbc kernel. This Kernel has insane battery life and a pretty good performance. If you do not want to use an sbc kernel i recommend for you to 100% use this kernel. The Governor for this kernel is set on on demand (i think) however i got the best battery/performance using Interactive.
GoDm0dE Kernel I also put the Zips in the Attachment (At The Bottom)
AOSP ICS ROM'S:
ICS rom by: the_Plattypus and it is still in Alpha testing. however the development for this rom is moving really fast so hopefully a beta will come soon.
EVO 4g Ice Cream Sandwich from source
ICS-evo-deck: This Rom is by kushdeck, After testing out Decks ICS Pre-Alpha 4 & 7 rom i conclude that although it is a alpha it can easily be used as a day to day rom. extremely fast and very snappy. only thing that i found not working was the camera. (Now on Alpha5)
[ROM][ICS][1-11-12][WIP] ics-deck-evo [alpha5]
All Decks ICS Pre-Alphas
All Decks ICS Gapps
AOSP ICS Kernels:
Jaredthegreat ICS - jared has the most advanced ics rom which is in beta 2 but does not have a working camera to check this rom go here:
[ROM's] -ICS- 4.0.1-4.0.3>[AOSP]<--~B.2.0~
Will post them when they are released!!!
Rom Manager/Kernel Manager:
Rom Manager: This is an app from the android market and is extremely useful for pretty much anything. you can back up your rom, you may go into boot loader and you can check if certain roms such as "CM7 Nightlies" have been updated. However people do prefer Amon Ra for flashing, which is another plus of Rom Manager it allows you to flash alternative recovery, which will flash Amon Ra for you.
Kernel Manager: This app was working before but has stopped now, however if it does start working again what it had was pretty much all the kernels that you needed for any rom. this app would allow you to flash a new kernel immediately by going to the kernel you want to flash.

Reserved
Q&A:
Q: What is SBC?
A: SBC stands for super battery charger. SBC is trickle charging, It stops your battery from dropping from 100% to 90% right when you take it off the charger. Some say that it harms your battery but i haven't seen any harm and plus it only costs $5 to get a new battery on Amazon.
Q: How to set up and flash your roms and kernels?
A: well my friend "Crossrocker" made a guide for this with everything you need. so just click to go to his thread. [GUIDE||Oct/23]Best AOSP(CM7|Decks|MIUI) configuration.
Q: What is the difference between governors?
A: This Thread by "RJackson" explains it all:SetCPU governors (explained)
But if you're too lazy to click it here they are:
As explaind by RJackson:
ondemand - Available in most kernels, and the default governor in most kernels. When the CPU load reaches a certain point (see "up threshold" in Advanced Settings), ondemand will rapidly scale the CPU up to meet demand, then gradually scale the CPU down when it isn't needed. - SetCPU website
conservative - Available in some kernels. It is similar to the ondemand governor, but will scale the CPU up more gradually to better fit demand. Conservative provides a less responsive experience than ondemand, but can save battery. - SetCPU website
performance - Available in most kernels. It will keep the CPU running at the "max" set value at all times. This is a bit more efficient than simply setting "max" and "min" to the same value and using ondemand because the system will not waste resources scanning for the CPU load. This governor is recommended for stable benchmarking. - SetCPU website
powersave - Available in some kernels. It will keep the CPU running at the "min" set value at all times. - SetCPU website
userspace
A method for controlling the CPU speed that isn't currently used by SetCPU. For best results, do not use the userspace governor. - SetCPU website
Interactive - The 'interactive' governor has a different approach. Instead of sampling the cpu
at a specified rate, the governor will scale the cpu frequency up when coming
out of idle. When the cpu comes out of idle, a timer is configured to fire
within 1-2 ticks. If the cpu is 100% busy from exiting idle to when the timer
fires then we assume the cpu is underpowered and ramp to MAX speed.
If the cpu was not 100% busy, then the governor evaluates the cpu load over the
last 'min_sample_rate' (default 50000 uS) to determine the cpu speed to ramp down
to.
As explained by MDJ:
SMARTASS GOVERNOR - is based on the concept of the interactive governor.
I have always agreed that in theory the way interactive works - by taking over the idle loop - is very attractive. I have never managed to tweak it so it would behave decently in real life. Smartass is a complete rewrite of the code plus more. I think its a success. Performance is on par with the "old" minmax and I think smartass is a bit more responsive. Battery life is hard to quantify precisely but it does spend much more time at the lower frequencies.
Smartass will also cap the max frequency when sleeping to 245Mhz (or if your min frequency is higher than 245 - why?! - it will cap it to your min frequency). Lets take for example the 998/245 kernel, it will sleep at 245. No need for sleep profiles any more![/QUOTE]
As explained by teh roxxorz:
Lagfree - like the performance governor. It will scale the cpu to higher frequencies when needed, but not to 100% like performance, so you'll get a lil better battery out of it
SmartassV2 - A smarter smartass governor. Code was re-managed/removed to make it more optimized, and have better scaling performances
InteractiveX - a better interactive governor I believe; low scale cpu settings, for texting, browsing, ect, nothing intensive. I wouldn't use it for emulators, ect.
Q: Do you need PRL/Profile/Radio updates? Do you need to go back to sense based to do these still?
A: No you don't have to go back to sense to do these and you don't have to do these because Rom's will come with what you need. None the less if you would like to update your radios here is a thread by "Calkulin" where he keeps the latest radios updated: [ Radios ][ 9-5 ] All EVO Radio, WiMAX, PRI, NV & HBoot versions
Q: Does HDMI mirroring work on these roms?
A: As of this moment Miui and CM7 both have HDMI mirroring working, and sense all the other ones are cm7 with some tweaks they as well have HDMI working however from what i have read the only one that has not had problems with HDMI is Decks Gingerbread Rom
Q: Are all other major features (4G (except for Miui), bluetooth, front & rear camera, GPS, apps such as Netflix, Skype, Google Voice, Sprint Visual voicemail) all working at least as well as on a Sense or stock ROM?
A: Yes everything is working, however on CM7 and i presume on some others you also have to flash a gps fix which you can get from this thread: [GUIDE||Oct/23]Best AOSP(CM7|Decks|MIUI) configuration. and the Voicemail seems to have some issues for some people but works flawlessly on Decks with it's gapps + Voicemail which you may also get from this thread: [GUIDE||Oct/23]Best AOSP(CM7|Decks|MIUI) configuration.
Q:My wifi is connecting/disconnecting after a second, what should i do?
A: This answer was given to me by "teh roxxorz." This has nothing to do with your rom or kernel, do this:
Back up everything into Titanium Backup
Boot into recovery
wipe cache, Dalvik, and pretty much everything
reflash your rom,kernel and gapps (or if you would like to check out some other roms and kernels just click on the link in my sig)
once you've set up your phone download Titanium Backup from the market
in titanium backup restore all your apps ONLY!!! (don't get apps w/ data - only get apps, and do not get system data)
after this your wifi should be working just fine
Q: I am having wake issues?
A: Here is a Guide made by JBabey[FIX] Wake Issue (Android OS) - Combination of Radio/PRI/NV/Wimax/GPS !Solved!
Q: Can i make my 3g speed faster?
A: Yes, This answer was given to me by teh roxxorz:
You need to flash a sprint sense rom. I emphasize sprint because it won't work on the sense 3.5 roms, as they're all ports of other non sprint roms.
1. Flash sense rom
2. Obtain your msl, download msl reader from market, use it, write it down
3. type in ##3282# , input your msl (you can get this from the app msl reader)
4. Click edit mode > advanced
5. Scroll down to HHTD proxy port and address
6. Change the proxy port to 0 and proxychange the address to 0.0.0.
Q: How can I fix my GPS?
A: This answer was given to me by teh roxxorz:
- flash a sense rom
- open up the dialer
- Type ##GPSCLRX# or ##4772579#
- Your enter your MSL at the prompt
- Your phone will soon reboot > done
Q: Is there a guide like this but for sense roms?
A: Yes if you are looking for a sense guide rather than aosp then check out this thread by tropicalbrit
Q: What is your setup at the moment?
A: Rom - Decks 4.0.3 Pre-Alpha 7 ICS Rom
Kernel - Stock
Governor - Conservative

Lagfree - like the performance governor. It will scale the cpu to higher frequencies when needed, but not to 100% like performance, so you'll get a lil better battery out of it
SmartassV2 - A smarter smartass governor. Code was re-managed/removed to make it more optimized, and have better scaling performances
InteractiveX - a better interactive governor I believe; low scale cpu settings, for texting, browsing, ect, nothing intensive. I wouldn't use it for emulators, ect.
Also, you should also disclose to people using Xplod: there's a 50/50 chance the new tiamat kernels [4.0.7+] may not boot, in that case, they should use 3.3.7.
And any reason you were gona message me?

Hi,
Thanks for guide... I am considering changing from
my stock rooted ROM, so very timely for me!
Some features that you don't mention or summarize
that may help me and others.
PRL/Profile/Radio updates? I believe you need to
go back to sense based to do these still? [yuk]
HDMI mirroring?
Are all other major features (4G (except for Miui),
bluetooth, front & rear camera, GPS, apps such as
Netflix, Skype, Google Voice, Sprint Visual voicemail)
all working at least as well as on a Sense or stock ROM?
Thanks in Advance,

My S3 ideal setup: ROM, Kernel, Mods, Apps & Games

In 2015, Galaxy S3 is a quite old device. It was introduced in 2012, with a lot of supporters around the world. I think it is the best smartphone of Samsung ever. And in 2015, it is still a good phone with latest software update from other developers
These are my combinations of roms, kernels, mods and tweaks of my Galaxy S3 (i9300). I think it is the best combination ever, with good performance and experience. Remember that this is my own opinion, so maybe it won't appropriate with somebody. Anyway, let's get start!!!
ROM
Cyanogenmod is undoubtedly the most popular and best-performance rom ever. It is based on Stock Android, so it runs very smooth and has brilliant performance, especially in Benchmark Test. Android 5.0 Lollipop is released, then our S3 has a very good CM12 rom with latest software version. I have used this rom for 4 months, and I do not expect anything more about my phone because it runs PERFECTLY.

​ KERNEL
Since Siyah kernel is end-of-development, Boeffla Kernel is a perfect alternative. This kernel brings us a lot of things : change CPU governers, overclock CPU (up to 1600 Mhz) and GPU (640 Mhz), sound tweaks, undervolt CPU and GPU, etc. It lets us to control our devices freely and effectively. It also gives us brilliant battery performance.

MODS
When I bought my Galaxy S3, I soon realized that is had a poor sound experience. So I looked for a sound mods that it improves my phone speaker. And fortunately, I have found a thread that had an amazing work: ACID Audio Engine. It gives me many positive improvements with i9300 sounds, and I have the best sound experience ever.

sorry for this,but,either u are not informed on whats going on these days,or just lack of knowledge.
this version you chose as your rom is EOL state,and its much worse than any rom IMO (memory leaks,stagefright not patched etc). the best rom right now is AD latest or B19 from archi as well.
kernel-wise,boeffla is EOL state again,he only update ramdisk,so this is just for campatibility still active.while things starting to end for this phone,archi wow us every single time,and archikernel latest is the most "optimized" for this phone along with his roms...
I/O sheduler-wise, deadline and noop is known to low speeds and performance crippling..best shedulers for our phone are BFQ latest,and CFQ.
ROW is better generally but not for I9300.it sucks.
You should never undervolt processor especially -75!! GPU as well. games will lag.
But this guide is,from my point of view,battery life driven.
but i would not get crazy for battery life anymore because anyways battery is fcked up so many years,especially stock.the only thing u will achieve is at best half an hour screen on time.not worth it for me
as for build prop tweaks,dont even touch it anymore,its not worth it,plus archi have better build prop tweaks and generally well made Roms.
*flies away*

My best setup is Archidroid + ArchiKernel
Cpu voltages table:
1400 1.1375V
1300 1.1V
1200 1.075V
1100 1.025V

600 0.85V
500 0.825V
400 0.8V

GPU:
700 - 1.175V
600 - 1.0625V
440 - 0.9375V
300 - 0.8375V
150 - 0.7375V
CPU Governor: lulzactiveQ
CPU States: IDLE + LPA + AFTR
eMMC/SD Governor row/cfq
I think, that we can undervolt our SoC much lower, but not by setting same '-xx mV' value for all profiles, i spend about 2 hours for testing voltages on every profile. I descended to 0.8V on CPU, lower values were giving me a lot of freezes and lags. On GPU i set 0.7V (Boeffla kernel) and image went away. My ASV level is 3. I also tried it on other i9300 @ 2LVL ASV, GPU was working with same voltages. But CPU wanted extra 25mV for every profile from my table.
I also saw one more thing, ArchiKernel requies higher voltages, but it's harder to freeze phone (especially GPU) than on Boeffla.
Sorry for my bad english, i'll improve that - i promise

i wish i didnt sold my s3 :/

[Benchmark][osprey] Testing custom kernels - performance & battery life

As a CM13 osprey user I found myself a little confused about the usefulness of custom kernels compared to the kernel bundled with cyanogenmod releases. There are many custom kernels available for the osprey, compatible with CM13. They mainly boast better performance & battery life and usually a lot of other features.
The purpose of this test is to measure the performance benefits and battery life benefits of the most popular custom kernels, if any. I want to find out if I should bother to use them myself, since the bundled kernel comes with the natural advantages of an easier install, better testing by the cyanogenmod devs and is updated, or has the potential to be updated, in line with the nightly releases. Perhaps some others will find the results interesting.
Setup
I'm testing on my 1 year old well used osprey running cyanogenmod 13.0-20160901-NIGHTLY-osprey.
All tests are single runs unless stated otherwise, phone in airplane mode. No special configuration is done to any kernel, so we're looking at their default settings.
Kernels
CM Bundled kernel
Squid r17
AGNi pureMOTO 3.2
FireKernel 5.6
Optimus R14
Shield r4
Explosion Reborn R24
Features
Custom kernels invariably come with many new features, sometimes a dizzying amount of stated improvements. I've highlighted some of the interesting differences that could affect performance, and a count of the bullet point features the kernels advertise.

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Only Squid & Explosion (based on Squid) deviate from the linux base version of 3.10.49. All custom kernels except Squid & Shield provide higher max CPU clock states. AGNi pureMOTO, Explosion and FireKernel provide a higher GPU max clock.
FireKernel boasts an impressive 91 feature worth bullet pointing, while AGNi pureMOTO doesn't feel the need to advertise any feature or even a mission objective. Well I'm assuming better performance, battery life and stability is at least a concern of all kernels.
Tests
PCMark emulates real phone usage, and is the performance test I'm most interested in to indicate general performance.
AGNi pureMOTO, FireKernel and Shield perform noticably worse than the bundled kernel. The other kernels are roughly in-line or a little lower than the bundled kernel, with only Explosion providing a hint of better performance.
It seems the kernels are providing higher max CPU clocks don't appear to be using them by default.
I didn't expect much difference in internel nand performance, but wanted to check for regressions. No kernels provide real storage i/o performance benefit. AGNi pureMOTO and Optimus have small performance regressions on sequential writes.
With 2D graphics mostly covered by PCMark, I'm simply checking 3D performance with a test provided by PassMark. Running at around 20fps on the bundled kernel, it seemed a good performance to spot any differences.
I was surprised to see poor performance from AGNi pureMOTO, FireKernel & Explosion. The other kernels are in-line with the bundled kernel. Kernel GPU clock differences seem to have no effect, certainly no good one.
To isolate processing performance I used a blend of multicore tests provided by Vellamo. All custom kernels performed worse than the bundled kernel, although Squid, Optimus and Explosion are very close. It's a disappointing showing from AGNi pureMOTO, FireKernel and Shield. As before higher CPU clock states do not seem to be used.
Looking at the figures I can't help but conclude that no custom kernel provides a worthwhile performance improvement over the bundled cyanogenmod kernel at their default settings. While this is somewhat disappointing, performance stats have little meaning without looking at battery life. This brings me to the most important and time consuming test, do custom kernels improve battery life?
Update: Battery tests completed 6-Sep-2016
Finally, after many hours of testing I have the battery test results. I used PCMark's battery test which runs the work usage test continuously until the battery reaches 20%. The test includes lots of emulated real world usage & lots of idle time. It also provides a geometric mean score for the entire run.
From the results we can see all kernels performing roughly similarly, but no custom kernel convincingly surpasses the bundled kernel for performance and battery life. Only Squid actually ends up with better average performance over the run, and at a small battery life cost.
Interestingly on viewing the CPU clock stats I saw the bundled, Squid, Optimus & Shield clocked between 800-1363MHz, whilst AGNi pureMOTO, FireKernel & Explosion clocked between 400-1363Mhz, and made more use of intermediate clock states. However, the lower clocks just haven't translated into battery life increases.
Concluding thoughts
All the kernels have performed decently, and without any stability issues during my testing. But it's the CyanogenMod bundled kernel that has surprised me by being front runner in speed & battery life.
For those of you enjoying unique features offered by custom kernels, you can take heart that the custom kernels aren't that much worse. But for me, considering the natural advantages of using the CyanogenMod's kernel, I'll be switching back to the bundled.

So this really does mean that going from 465 MHz to 720 MHz makes 0 difference, when it should considering it's supposed to be delivering a 50% performance boost.

That is the case for me yes. The higher clocks are stated as features, and max gpu clock is observable as a setting using Kernel Adiutor. However, looking at the results I'd guess the gpu & cpu just aren't actually being clocked to max.

great work.. waiting for battery life...i think some other roms gives good battery life other than cm13

Cm 13 kernel 28000 score
Firekernel 31000 score

Maybe the new version of firekernel 5.6 is beter.

Very interesting. Overall it seems stock cm kernel is a better choice. Would be interesting to see how stock Moto stacks against stock cm on these tests.

I'm onto the 3rd kernel battery test. The good news is PCMark provides a nice geometic mean performance score of the entire run, so I should end up with pretty good figures for performance vs battery life.

so whats the best kernel right now

Great reply, no not just great, stunningly epic reply mate backed with nothing. Nice, you totally dismissed all evidence here, great job.

here the backing on my statement.
it's just some simple benchmark etiquette
don't benchmark kernels using their max oc frequency as not everyones device Will be able to perform well on the specific custom kernels defaults
(due to minor cpu/gpu quality inconsistency)
also custom kernels usually have different io,
cpu, hotplugging and zram settings and parameters set by default.
it's better practice to set the cpu and gpu to the same frequency and governor, Same Io scheduler
and readahead etc. same zram settings.
then test these settings across the kernels to see which kernel has more efficient system management+ Performance
otherwise it's just a case of which kernel has the best default parameters and settings.

and then what do you mean exactly by laggy, what s the situation in which this happens

it will be great if u add the best rom too. like performance and battery life withits stock kernal

[REQUEST] Stock Kernel with KCAL?

Hi, this is a friendly request for the senior devs on this forum. I am actually a noob when it comes to kernel compilation. So I wanted to ask if anyone here has already compiled or is willing to compile the latest stock kernel (from 3.6.1) with no other features except kcal controls. Because me and other OP2 users feel that battery life is best on stock kernel but the washed out display is absolutely disgusting. Also if it's not possible just us know, thanks in advance!

Did you try boeffla's kernel? gives much better battery life than stock for me (1/3 longer, in any scenario i tested it).
If you still want to have stock kernel here are the kcal commits. just set up Virtualbox Ubuntu, set up build environment , download official op kernel source (the 6.0.0 version!) and cherry-pick the commits (google it).
If the effort is not worth it, use boeffla's or stock without Kcal.
I can try to help you if you're stuck, but mind that i'm just starting with compiling stuff myself.

Yeah man I have tried boeffla. Performance is okay but battery isn't as good as stock imho. Maybe my settings affected it. Can you tell me which version of boeffla you use and what settings so maybe I can replicate your results. Thanks man.

Sure, i use boeffla 2.4-beta5, interactive battery extreme governor (u can tweak max frequency on little to 1200mhz), set little cores (i use 2, you can set it to 3-4 for more performance) set big cores to min0, max0 (if you need power to play games etc. set to min0 max 1-2) GPU underclocked to 27mhz, boost disabled, governor adreno (or powersave, might gives lags)
Further i installed xposed, greenify, amplify (there is a free version, but u have to compile it by yourself--> easiest with android studio).
And i followed this thread to maximize my battery life.
Tried several rom and kernel combinations, with this setup i get a sot of 5-6h with 48h of not charging or 7-8h in less than 24h. But on Lineage 13 its even better... (trying to compile a custom oxygenos, debloated, without playstore, F2FS capable right now but not able to activate F2FS)
If you're interested in the ext4 image, tell me (its untested though).

Damn dude these settings sound a bit extreme doesn't your phone lag like hell lol. And oh hey that sounds really interesting! Is it based off 3.6.1? And what kernel have you implemented it with. Right now I'm testing HalogenOS (loving it so far) but when I feel like switching again I would love to try your build. Link me!

I don't even have microlags (with other kernels and this settings it lags like hell, idk why boeffla doesn't)
However, app opening speed and switching between apps is a bit slower than usual).
Idk what the official source's base is (i guess 3.5.8) as i could'nt boot it up yet. Kernel is original kernel (with F2FS activated by me), i'll change this when it boots with f2fs.
I'll send you the link when i have time
