WARNING :
This kernel is only for Galaxy S3 International (GT-I9300) version,
and running Android 4.3 (Samsung ROM's) !
Click below to read the full story..
Many of you knows already knows me from my older LiteGX kernel series (for Android 4.1.2 & 4.3).
This time for SimpleGX, I would like to be closer of stock than LiteGX by removing a lot of unneeded things which finally were not gaining any battery stat at all. I had to review everything from zero (once again !).
SimpleGX is only looking for simplicity and stability, trying to aim for best battery life, smoothness and performance experience, than a pure stock kernel.
SimpleGX will now abandon all scripts that I created for LiteGX (even if some of them are still compatible but not recommended).
I really would like to create back a kernel which was my main idea, a kernel “flash-and-play”, nothing to configure, no need to be a nerd, every newbies can have directly best battery life and smoothness once flashed. Of course that’s every kernel cookers wants, but I would not qualify mine as a real “custom kernel”, since it’s not offering any app to configure it and having much more opportunities, at the cost of many random instabilities (freezes, lags, reboots, etc).
There is many differences between LiteGX and SimpleGX, you will have to compare threads if you want to know them.
I really would like once again to give a huge thanks to my friendly devs (post #3) who helped me a lot during all kernel building phase, learning me, and making adventure possible. I can tell also that Google is really a good friend, I confirm that ^^
I still don’t qualify myself as of a real developer, but just a basic person with some android/linux knowledge already.
As always, I’am enjoying sharing my contribution here on XDA for free, which taking me a lot of time to release, so if you can offer me a little beer (as I’am still jobless yet), I will really appreciate that and you will be added into post #4 ! LiteGX had more than 10000 total downloads, I let you imagine if everybody gave me at least a single dollar ! ^_^
This kernel must be only flashed over an official Samsung ROM and not AOSP/AOKP !
Feel free to include my kernel to your ROMs / Threads but please don't forget to inform/ask first via PM and credit me in your original thread.​

i will try this one out
by the way, is there any app by which i can configure the settings? like Stweaks or Boeffla Config?

It's a plug and play, but if you want, you can try trickster for setting stuff like zram on or off, but nothing much to do though.

Your Kernel really rocks. I have been always using your Kernel for close to stock. I am still using LiteGX.
I have tried several one but was looking for one which is hassle free. Your is the one.
This one I will not use now due to USB tethering broken, will wait for next version with that fix.

As long as you flash it on android 4.3 and that the automatical script during procedure won't stop you before checking, then you are good to go
When samsung release his (for example 4.3) source, you can be sure that it will be compatible with every 4.3 future coming firmwares :good:
Sometimes a ramdisk upgrade can also help in some case, so if needed I will do it, no worries

As stated in the story part of post #1, and as Mosh Edd said, this is a flash and play kernel :good: but you can still configure governor settings or some options directly via TricksterMod/SetCPU, etc (don't forget to keep settings after rebooting).
Mosh Edd said:
like zram on or off

I intentionally disabled stock ZRAM which was on by default via defconfig so no way to activate it manually :angel:
I decided to always disabled it now on SImpleGX, since zram is eating battery a bit and after some ours of use you will face some random lags.

I informed Lord Boeffla about this bug which affects every kernels, he will take a look as soon as he can :good:
By waiting, I will maybe release a "no_IUPC" (no Ignore Unstable Power Charging) version in parallel for each releases, so each one will choose directly if they prefer fast charging or slow charging but with USB tethering working. I intentionally used IUPC as default because wifi it still working to share (for the few I'am using it..) and that I prefer to not wait hours to charge only 10% of my device

Thanks for the reply mate. I just installed and all seem to be fine so far. will test couple of more days and update here.
BTW do we need to clean init.d folder ? i know boeffla andi frequently recommends cleaning up init.d folder. is this necessary with your kernel. Note, i dont have any issues so far (only used few mins though).
Thanks for the advise.

He is right because some init.d scripts can affects stock settings from governors for example or try to enable/disable things that is not from my kernel, etc :good:
For exemple, I'am using NeatROM 6.5 and I can see that there is a lot of scripts in init.d already by default bur they don't affect any of kernel part so it's ok
There's no other solution that checking manually each of them, sadly.

Hi,
Thanks for the new kernel!
I come from the latest LiteGX kernel, so I run the cleaner script before flashing this one. My phone hangs when I reboot. I restarted my phone to get it to boot, but then I now have SwiftKey not loading. What could be the problem?
I reverted back you LiteGX for now.
Sent from my GT-I9300 using Tapatalk

I flashed kernel last night and waited until phone settled. Checked if all works fine, and it does, and then put the phone in flight mode.
This morning I checked battery stats and it looks like battery was charging a bit while in flight mode (phone was not connected to any power source).
Funny
All is super smooth. Thank you :thumbup:

Strange, as I'am using SwiftKey also and no problem here. If phone hangs at boot this it not normal, did you tried to re-download the kernel from first post ? (maybe a bad download).
If problem still here, maybe try to Try to wipe cache + dalvik from your recovery :good:

By waiting, I advice you also to try a wipe cache and dalvik before reaching another 100% and disconnect again to verify :good:
I will try this night aswell to confirm or not if I have the same bug

3.0.31? Why no update to 3.0.101?

[ROM] [6.0.1] [Build 4] [03/04] Unofficial CyanogenMod 13.0

Introduction
This ROM is inspired by JustArchi's build optimizations that provide up to 6x performance boost .​
I am not a developer by any means, I did my homework and I figured out how to compile and cherry-pick cool things. I am open to advice and guides that can help me make this ROM even better, you can also always ask for features and I'll do my best to bring them in.
As this is my rom for daily use, it contains many, many tweaks and endless hours of work of the best devs of XDA. In these features you can find Faux's Intelliplug, Yank555 powersuspend driver and many other stuff. At this point if you use any other kernel with my ROM you will lose about 80% of the features and the experience I want to provide will be lost. If you like other custom kernels such as Pink please kindly use official Nightlys.
If you are still here and haven't ran away you must know that you can always ask me for new features you see in other fine roms (Such as Temasek, CrDroid, etc) and if everybody like that feature (Including me) I will gladly bring it into the ROM. Don't forget that if you want a full featured ROM there's plenty of fine choices. The main idea with this is the same as with my old CM11 builds; "To stay as close to Stable CM as possible while adding on a little somethin' somethin' to make things better."
DISCLAIMER: I am not responsible for any damages to your device, always have a nandroid on hand if anything happens​

Build 15.1
-Finished bringing features of old kernel to the new one
-Implemented misc build.prop tweaks (Commit)
-Introduced Opti-Charger (To improve RAM use, more info in the spoiler)
Custom ROMs in the beginning had limited space to work with which is why Cyanogen introduced opticharging to the custom release tool in order to shrink apks to fit more apps on system partitions of the original android devices. The opticharger script pulls apart apks near the end of the build and optimizes all pngs drawables found in them. Originally this script used optipng which is great and there is absolutely no quality loss involved in the png compressions but more recently I’ve begun using pngquant because it compresses pngs even smaller 30-70% with usually an average of about 50%. Pngquant does result in a slight loss of quality but nobody has noticed yet (See more on pngquant here: http://pngquant.org/) (If you are worried about quality you can always use optipng which compresses without any quality loss themers usually use this option instead)
Currently, CyanogenMod has abandoned the use of the opticharger but many ROMs still use it such as SLIM, AOKP, LiquidSmooth, Dirty Unicorns, Carbon, Validus, and many others. Themers and app developers alike use these techniques as well to make their apps/themes run more smoothly. Making pngs 70% smaller actually makes the loading time 3 times faster for these pngs and also saves you RAM. I understand apks aren't all pngs but you'd be surprised how many junk pngs google has left behind since froyo that serve no purpose but are loaded into your ram with SystemUI anyways. Thankfully opticharging shrinks all of those undesirables by usually 50-70% and saves you several MB worth of space and speeds up your SystemUI. Since you can't unload the system UI this is well worth the effort! My motto always is every little bit counts
Many still argue that high end device don’t need opticharging anymore because they are fast enough to handle these full-sized pngs. While this is true it still doesn’t change the fact that opticharing IS still slightly faster and opticharged apks do use less ram

Important changes:
- Optimized for speed yet more all instructions - ARM and THUMB (-O3)
- Optimized for speed also parts which are compiled with Clang (-O3)
- Turned off all debugging code (lack of -g)
- Eliminated redundant loads that come after stores to the same memory location, both partial and full redundancies (-fgcse-las)
- Ran a store motion pass after global common subexpression elimination. This pass attempts to move stores out of loops (-fgcse-sm)
- Performed interprocedural pointer analysis and interprocedural modification and reference analysis (-fipa-pta)
- Performed induction variable optimizations (strength reduction, induction variable merging and induction variable elimination) on trees (-fivopts)
- Didn't keep the frame pointer in a register for functions that don't need one. This avoids the instructions to save, set up and restore frame pointers; it also makes an extra register available in many functions (-fomit-frame-pointer)
- Attempted to avoid false dependencies in scheduled code by making use of registers left over after register allocation. This optimization most benefits processors with lots of registers (-frename-registers)
- Tried to reduce the number of symbolic address calculations by using shared “anchor” symbols to address nearby objects. This transformation can help to reduce the number of GOT entries and GOT accesses on some targets (-fsection-anchors)
- Performed tail duplication to enlarge superblock size. This transformation simplifies the control flow of the function allowing other optimizations to do a better job (-ftracer)
- Performed loop invariant motion on trees. It also moved operands of conditions that are invariant out of the loop, so that we can use just trivial invariantness analysis in loop unswitching. The pass also includes store motion (-ftree-loop-im)
- Created a canonical counter for number of iterations in loops for which determining number of iterations requires complicated analysis. Later optimizations then may determine the number easily (-ftree-loop-ivcanon)
- Assumed that loop indices do not overflow, and that loops with nontrivial exit condition are not infinite. This enables a wider range of loop optimizations even if the loop optimizer itself cannot prove that these assumptions are valid (-funsafe-loop-optimizations)
- Moved branches with loop invariant conditions out of the loop (-funswitch-loops)
- Constructed webs as commonly used for register allocation purposes and assigned each web individual pseudo register. This allows the register allocation pass to operate on pseudos directly, but also strengthens several other optimization passes, such as CSE, loop optimizer and trivial dead code remover (-fweb)
- Sorted the common symbols by alignment in descending order. This is to prevent gaps between symbols due to alignment constraints (-Wl,--sort-common)

FAQ
Thanks a lot @Travisholt92 for writing this guide, please give him a big thanks here!
Question 1: I am coming from (Stock or CM11), how can i install this?
Answer 1:
1. Back up all of your files, text messages, and everything else that you dont want to lose (try Easy Backup in the Google Play Store). You will lose everything stored on your phones internal storage and applications , your SD card will be safe.
2. Download the latest build posted in OP and Download GAPPS and move the .zip files onto your SD card (Remember where you put these files).
3. Shut down your phone.
4. Reboot into recovery mode by holding down the volume down button and the power button, then releasing the power button. This will come up with the Fastboot interface. Press volume down to highlight Recovery and then press volume up to boot into recovery mode.
(through TWRP)
5. Press Wipe
6. Press Advanced Wipe
7. Select Dalvik Cache, Data, Internal Storage, Cache, and System.
(Do not select microSD card or USB OTG)
8. Swipe to wipe.
9. Press Install. At the top of the screen make sure it says "Storage: microSD card". Navigate to the ROM .zip file and press it.
10. Press Add More Zips and select the GAPPS .zip file.
11. Swipe to confirm flash, reboot system, enjoy SaberMod!
(If none of these answers fix your issue read the comments for others having similar issues to see if anybody has found a fix for the issue. If the issue hasn't been meantioned previously please report the issue, leave a comment. Make sure to state what build you are running and what kernel you are using if you installed a custom kernel. If its something that happens when you perform a certain action such as after sending a text your phone reboots, try and be as detailed as possible when reporting the bug)
Question 2: I just installed (insert build name here and issue below). How do i fix this?
A. and my device is stuck at boot animation, device boots but spams with system application errors (meaning installed by your ROM not from GAPPS) , or anything else that prevents you from using your phone.
Answer: Backup your device and follow the directions for answer 1. (install the last ROM you were running if you are coming from an AOSP build if needed to back up your data)
B. and my device boots but spams with my downloaded application errors.
Answer: Uninstall the application and redownload it from the Google Play Store.

Gonna test
Que buena ver un chileno por estos lares, y más aun desarrollando roms, bastante bueno; voy a probar la ROM y ver como anda

Only CM11 bugs, wich at this stage of develeopment are almost zero. That's the idea of applying only minimal stuff, the result is a enhanced CM11 experience with the same stability.
Next build will inlude GPU and RAM OC.
.

I also prefer CM 11 for now. Better stability and performance. And your ROM is great! No bugs so far. Thanks!

BUG
I Got Alll cores running on 1190hz all time and i can't change the frequencies

It is not a bug, MPdecision shows all cores at full freq, but if you check them at real time (I.E using CoolTool) you'll see they work normally.
Anyway, I DK if add more features on the next build (Halo maybe?) or keep things simple with Linaro and Archi's optimizations. What do you guys think?

keep it simple, there are other ROMs for those who want more.
or you can make it modular and give additional functions in flashable zips

I Think that modular add ons wolud be great , btw i would like more perfomance improvements too:good:

Wonderful job, hermano trasandino'. One thing I'm missing is the Tap2Wake feature. How can I add it to this ROM ?
Thanks

I'm guessing there's still this mystical memory leak problem as in CM11?
Sent from my XT1039 using XDA Free mobile app

New build is up. Currently I'm adding general tweaks before fetching more advanced stuff. (I'm having a lot of fun on Blechdose's AeroKernel and Faux github )

Yes. That's the way I've done it. Just simply erase everything EXCEPT sdcard and usbotg. Then, as usual, flash this ROM and then Gapps

I've been using it since yesterday and the perfomance is amazing! I will keep this as a daily driver, just one problem: sometimes the camera doesn't take the photo, it freezes just after I push the botton (I had the same problem on CM12).

Glad to see there's actually someone using and enjoying it. I'm having pretty good battery life and performance too, I guess Linaro and JustArchi's optimizations are just magical.
Regarding the camera, I don't use stock CM11 app but "A Better Camera" from the PlayStore. GIve it a shot and tell me if the issue persists.
Regards!

Great, I will try it. By the way, there isn't block screen notifications on the rom? That would be a nice feature if you can add it and keep up the good work, I'm staying with this.

After a successful boot again reboot your device! you will feel the speed!
Requirements:
1.A kernel with init.d support!
If your kernel doesn't feature init.d,you can emulate init.d by kernel adiutor/universal init.d
2.A custom recovery(clockworkmod or TWRP)
Caution--->Do a nandroid backup! Before doing anything if something goes wrong you can restore your rom using that backup!
This mod is stable and safe.There are extremely extremely less chances that the mod will brick your phone!
But you must take precautions !

Seems to work pretty well on my old gt-s5300, so thanks! Will you also port your v4 from s5360 over?

I will stay tuned

v5 released

The phone sometimes turns off if idling to long, could this be related to your performance mod?

Would be great if it worked on stock but otherwise great job.
