This kernel is the result of a study aimed at achieving a balance between performance, efficiency in resource consumption and stability of use.
In any case I do not have the presumption to say that I reached the goal, for two reasons: it is still a project work - in - progress and secondly keep in mind that I am simply a person with a minimum of experience that attempts to understand how does a linux kernel and above all trying to figure out what are the implications of the introduction of a change compared to another.

CHANGELOG
SpeedWizz kernel 01/22
Changelogs from version 01/17
- More workaround to gain stability and exactly:
- input: evdev: Move wake_lock_destroy call
- ext4: prevent kernel panic in case of uninitialized jinode
- updated toolchain to 4.7.4 (target linux kernel 3.0.101, the actual kernel state)
- Boeffla-Sound: Engine 1.6.5
- mmc: disable crc for better performance
- Added some script to handle GPU threshold (psndna88 for inspiration)
- When flashing zip version from recovery you will get a backup of init.d folder BEFORE this will get erased, directly on your internal sd card.
Changelogs from version 10/8
- ONLY for Samsung 4.3 JB rom
- Based on latest kernel sources from OSRC n7100-update3
- Linux kernel version 3.0.101
- LZMA compression for zImage and initrd.img
- CPU Boost driver
- Gentle Fair Sleepers disabled from kernel code
- SELinux is present but it's disabled at each boot.
WARNING: in case you want to switch to a different kernel that lead to SELinux permissive or enforcing mode you MUST reflash your rom entirely and then flash a different kernel. SELinux needs to boot on a labeled system: until you run a disabled selinux kernel labeling is NOT present and system will refuse to work unless you perform a labeling again.
Be aware.
- Ported almost all the features from old 4.1.2 kernel:
1. Overclock up to 1920 mhz
2. Undervolt
3. GPU control - undervolt and overclock
4. Many optimizations
5. Fade led notification
6. TouchWake with slide2wake feature (timeout 0)
7. zzmoove, pegasusQ, LulzactiveQ and others governors
8. Sio, row, zen, cfq, deadline (tweaked) and noop schedulers
9. Proportional rate reduction for TCP congestion
10. Disabled many logs
11. Android logger as module
12. Frandom built-in
13. Dynamic file system synch
14. Boeffla sound engine
15. Zipallign optional feature
15. Post-init tweaks
16. Init.d full support with busybox run parts
- Rewritten all the scripts to make them working with the new kernel code (due to some changes on GPU Overclock and undervolt). You can use the embedded app to configure almost every feature of the kernel, enjoy!
SpeedWizz kernel 10/08
Changelogs from version 09/30
- Triggered experimental option flags for compiler
Introduced two new flags: Graphite optimization and Link Time Optimization
- Reverted and re-applied (i hope in proper way) the fast charge feature
Beta testers reported as working, after the above correction.
- Enabled sysfs interface for frame buffer early suspend delay
Now we are able to set the delay using proper sysfs interface, with a range of options from 0 milliseconds to 700 milliseconds. To easily configure we can use speedwizz manager.
- Permanent filesystem TRIM
- Totally disabled samsung debug
- Linux kernel 3.0.99
- RAMDISK: Added earlysuspend delay related scripts.
For more details please refer to my github.

SpeedWizz kernel 09/30
Changelogs from version 09/24
- tmpfs: fix mempolicy object leaks
Patched mm/shmem.c to avoid several memory leaks caused by mpol allocated memory, errors parsing remount options will leaked mpol and multiple mpol per mount leak mpol. Credits as per related commit. Follow the link on description.
- mach-exynos: cpuidle-exynos4: set logging default to disabled
Trying a proper way to optimize kernel resources usage. From gokhan moral source tree.
- power: reduce regulator initializations to regulator minima
With this modification we now use more undervolt (less voltage level) for Gpu and running stable.
Before applying this patch, I can't use even -25 Mv. Now i can reach a stable -75 Mv without crash neither graphics glitches.
Anyway, at the moment, the undervolt scripts in ramdisk are the same of the previous release.
- cpupower: update the cpu_power according to cpu load
When the lowest frequencies are used, we are in a light load use case and we increase the cpu capacity to keep these light tasks on CPU0. This patch was originally used by AndreiLux in his Perseus, and i think it could be implemented to reach a better balance between performances and battery life.
- Correctly applied the screen sharpness to our hardware
- Moving boot partitions to probe
This should grant Triangle Away support, need to be tested by others than me.
- Added fast charge - thanks Yank555-lu
With this modification we now should, i repeat SHOULD, be able to use the same power output for both A/C and USB charging case. And also we should be able to set our custom power level for both.
Default is disabled, you can use speedwizz manager to set things as desired.
PLEASE IGNORE THE OUTPUT PRINTED BY TRICKSTERMOD, i will investigate why it show an ENABLED message despite the real state of the sysfs interface.
Also you should know that for your safety i deliberately omitted the option to enable FAILSAFE: It can be used to allow anything up to 2.1A to be used as AC / USB custom current. The sysfs interface is there but there isn't a script to manage this option because i think it's too dangerous for your data. Use it at your own risk.
- Linux 3.0.74
- RAMDISK: Corrected almost all scripts to let show the coerent increasing order as per choice.
- RAMDISK: fixed the scripts for sched_mc_pwersavings, now will echoes the correct values.
- RAMDISK: simplified the GPU overclock scripts removing the frequencies steps from description choiche menu (i noticed overlapp between values). Now you will see only Low, Medium, High, High+, High++.
- RAMDISK: Added the related scripts for all the new features.
- RAMDISK: Made the Zipallign feature as optional. Use the speedwizz manager to manage the feature.
- RAMDISK: removed the option for manage the gentle_fair_sleepers, as this debug feature is totally removed since 24/09 release, sorry for the inconvenience.
DOWNLOADS
Can find kernel zips and tar on the top of the page linked below
INSTALLATION
Download kernel as zip archive and put in recovery. Reboot in recovery and wipe your cache. If you are switching trough kernel compiled with different toolchain a wipe dalvik-cache is also suggested. Flash kernel and reboot.
If you are using Odin (mobile or desktop) than download kernel as TAR archive. Reboot in recovery once time to wipe cache and (optional) dalvik-cache. Turn yor phone off and rebbot in download mode. Attach usb port to a PC (make sure you have installed proper drivers) and open Odin program as administrator: connect phone to usb cable and wait for communication port initializing. Now select from PDA tab the TAR file with the kernel and click on start. Wait for the process until it ends and when your phone reboot de-tach usb cable. Enjoy!
HOW TO USE
To configure kernel parameters you can use SpeedWizz Manager inlcuded application. This app is based on the original script manager written by HMCarbide (thanks for let me use).
After flashing the kernel in /res/scripts (on the root of the ramdisk) will be stored many scripts that, when selected using the app, will be loaded in init.d folder and will be executed instantly. For each option selected corresponds a script. This is a work in progress, and in future will be added many more option to let configure the kernel for almost all the supported features.

NOTE1: The options selected will be operational ALSO at each reboot. If you accidentally have enabled some weird option (too many low voltages for example) to make your device boot properly you may need to reset the init.d folder and remove all scripts from here. JUST reflash the kernel using RECOVERY: in updater-script there is a command that will remove totally init.d folder and his contents.
At next boot, kernel will create a new folder.
At next boot, kernel will create a new folder.
NOTE2: To enable logcat just run speedwizz manager application and hit the check box related. Reboot and use logcat normally. To disable open application and deselect that option: at next boot logcat is disabled (this is the default setting).
NOTE3: Kernel comes with autoroot. So if you don't care of counter increments you can flash this on top of a stock rom to obtain root and busybox. On the other side, if your phone is already rooted or have busybox or both, the root process is bypassed leaving untouched the situation.
To disable root (for example to use SkyGo application or similar) just create an empty file called
Code:
noroot
in your sdcard and reboot. At next boot kernel will remove root feature TOTALLY. To re-enable root just delete this file (of course you can use stock file manager to do this, no root needed
) and reboot again.CREDITS
