(thank you for the picture, Lt.Win)
Before I begin, I'd like to thank:
thachtunganh - for teaching me everything from downloading the source code to compiling the kernel
DJNoXD - for tips on kernel development and support for P505/P506
Turducken - for tips on kernel development
hephappy - the 2.6.35.14 kernel is based off his CM9 kernel
androidarmv6 - the 3.0.8 kernel is based off of this team's kernel
thachtunganh, DJNoXD, franciscofranco, Rashed97, williamcharles, and many other developers - making patches to this kernel possible
WidowCranky and engr_exxi - providing me with very valuable feedback
you - for testing/using this kernel. Thanks again!
Just a quick summary of this kernel (you can find more info in the changelog):
Compiled using CodeSourcery
Updated governors (interactiveX, conservative, ondemandX, powersave, SmartassH3, performance)
Google Snappy Compression for ZRAM
SLQB memory allocator
optimized touchscreen from thachtunganh
BFS/CFS cpu scheduler
If there are any features you would like to see, I'll try my best to include them.

Supported devices:
P500, P505, P506, P509
Supported ROMs:
All kernels are built for ICS. CM9.2 uses the 3.0.x kernel. All other ICS ROMs use the 2.6.35.xx kernel. If you are not sure, find out your current kernel version by looking under Settings > About Phone > Kernel version.
FPChaim and edinrh have tested this on GB and reported that it broke video playback, so don't flash this on GB unless you don't mind losing video playback.
The newer versions of CM10/CM10.1 will not be supported, as they require triple buffering in the kernel. It is too much of a hassle for me to make a separate build just with it enabled. This is not to say that this kernel will not work on JB; it is just your experience may not be as smooth as it could be. Please use androidarmv6's kernel for that.
Why I built this kernel:
I wanted to compile an ICS kernel using a clean base kernel for a little gaming. To do so, I've included franciscofranco's touchscreen driver from his GB kernel and implemented the BFS CPU scheduler. Also included are some performance patches.
Flashing the kernel:
Before flashing, remember to have another kernel to flash or a backup in case anything goes wrong. Flash this kernel like any other kernel. Don't forget to wipe cache and dalvik cache.
Changelog:
You can find the changelog at my Google Code or in the following two posts.
Headers that are in bold refer to new releases.
Downloads:
You can download the latest and previous releases of the kernel at:
http://code.google.com/p/sweetnsour-kernel/downloads/list
Why Google Code? Google Code is free, provides fast downloads, and allows me to keep track of the number of downloads. This is important because it allows me to determine which kernel users prefer (BFS vs CFS, most importantly). As such, I ask that you do not mirror any of the kernels.

Want to Compile Your Own Kernel?
Code:
1. Fork the repo of your choice on github. Now that you have a fork of it on your github, download the source by entering the following in Terminal:
git clone [SSH address of your fork]
2. Set PATH for the toolchain (GCC 4.4.3 will be used as an example)
a) Clone the toolchain repo, and then copy the folder to Home. Open Terminal and enter "sudo cp arm-eabi-4.4.3 /opt/arm-eabi-4.4.3"
b) Enter "gedit .bashrc" and add the following:
# others
PATH=/opt/arm-eabi-4.4.3/bin:$PATH
export PATH
Restart your computer to apply changes.
c) Go to kernel source. Open the Makefile and look for:
ARCH ?= $(SUBARCH)
CROSS_COMPILE ?= arm-eabi-
CROSS_COMPILE ?= $(CONFIG_CROSS_COMPILE:"%"=%)
Make sure the second line is set to arm-eabi-.
3. Make kernel config
a) Look for the appropriate defconfig file under /arch/arm/configs.
In Terminal, enter "make [name-of-defconfig]". This will create a .config file in the root of your kernel source.
b) Use "make menuconfig" to enable/disable kernel features.
c) After "make menuconfig", copy the contents of .config back into the defconfig you used from /arch/arm/configs. A shortcut for this is to create a file called "def" at the root of your kernel source. Paste the following into the "def" file:
#!/bin/bash
# This command will copy your kernel config to the defconfig folder.
# Change "yourkernelname" to what name you like,
# change "androidosversion" to what android os version that you design kernel for.
cp .config arch/arm/configs/cyanogenmod_p500_defconfig
Change the directory to that of the defconfig you used.
In Terminal, cd to your kernel source and make the "def" file executable by entering:
chmod +x def
Run the file by typing "./def"
4. Compiling kernel
a) To clean up the kernel source, use "make clean" to delete any already-compiled files or "make distclean" to clean up more files including .config. At this time, use "make clean".
b) Compile the kernel using "make -jx", where x is the number of CPU cores your computer has plus one.
5. Zipping the kernel
a) Create a directory called "android" and within that folder, create a folder called "releasefolder" by entering the following in Terminal:
cd ~/
mkdir ~/android
cd ~/android
mkdir releasefolder
b) To create a zip of the kernel, you will need the AnyKernel template. Enter the following in Terminal:
git clone [email protected]:austinay/AnyKernel.git -b p500
c) Just like with the "def" file, create a file called "zip" at the root of the kernel source and paste the following into the "zip" file"
#!/bin/bash
clear
now=$(date +"%Y%m%d_%H%M")
# Copy the new modules and new zImage to Anykernel folder.
cp drivers/net/wireless/bcm4325/wireless.ko ~/android/AnyKernel/system/lib/modules
cp arch/arm/boot/zImage ~/android/AnyKernel/kernel
# Creat flashable zip file
cd ~/android/AnyKernel
zip -r name-of-flashable-zip-file-${now}.zip *
# Drop it to release folder
mv ~/android/AnyKernel/name-of-flashable-zip-file-${now}.zip ~/android/releasefolder
Change "name-of-flashable-zip-file" to the name that you want to give to the zip of your kernel.
In Terminal, enter "./zip" to create a flashable zip.
COMMANDS
git clone [ssh address] - clone a repo
git branch [branch name] - create a branch
git add [path] - stage a modified file for committing
git add . - stage all modified file for commiting
git commit -m "your commit here" - commit staged files with your commit name
git commit -a - includes both "git add ." and "git commit -m"
git push - push changes to github
git push --force - force changes to be pushed to github
git push [remote name, which is usually "origin" for a forked repo] [branch name]
git clean -f - remove untracked files
git clean -f -d - remove untracked directories
COMMITS/PATCHES
After making changes to the kernel, push these changes as commits using the appropriate commands above.
To apply a commit (from another repo) as a patch, enter the following in Terminal:
git remote add [remote name] [repo SSH address]
git fetch [remote name]
git cherry-pick [SHA1 of commit]
To roll back to a certain commit, enter the following in Terminal:
git reset --hard [SHA1 of old commit]
git push -f
To patch the 3.0.x kernel to the latest version, look here:
http://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/log/?h=linux-3.0.y
To apply a patch file:
git am [name-of-file].patch
OTHERS
To pull a newly created branch from the original repo, use:
git fetch [remote-name] [remote-branch]:[new-local-branch]

I think because there is nothing original by sweetnsour... when he makes commits or such, he may ask the mod to move to original section
Re: [KERNEL][GPL][ICS] sweetnsour.kernel
If a list of flashable recoveries can belong to original devlopment then why not this?
Anyway its smooth but still a long road to go. Will report about battery and game performance tommorow

I never thought our phone was meant for multi-tasking (and I hardly multi-task on it anyway), which is why I implemented BFS. I like how BFS focuses only on the foreground app :victory:
Re: [KERNEL][GPL][ICS|2.6.35.14] sweetnsour.kernel-version1
Heyy, what a good surprise!
I just want to say that this kernel(both versions) work in gb(tested on cyanmobile), I haven't tested bt and gps but they should work.
Thanks for the kernel, will use it and give more feedback

Kernel Special Features: Customized kernel 3.4.x for JB 4.2.2 rom (CM 10.1 and derivatives) with ION memory allocations
Version Information
Status: Stable
Current Stable Version: v2.0
Stable Release Date: 2015-02-09
Created 2013-12-16
Last Updated 2015-06-08
Special features and sysfs settings (Part 1):
Here you can find some useful scripts that can be used with the following described features:
Scripts
Phantom Key Presses filter
This feature is an attempt to workaround a well known hardware bug of some Samsung devices.
Pratically, the high activity of the radio hardware, in particular the antenna, could cause interference on Melfas chip, which is located very close to the antenna.
This interference could induce bad interrupts that are seen by the chip as possible HOME, MENU or BACK key presses.
These phantom key presses are happening expecially in 2G mode.
The solution includes a new device module (phantom_kp_filter), which also allows the filtering parameters customization, and various changes to cypress-touchkey and pmic8xxx-keypad modules.
The phantom key presses filtering is enabled by default for incoming MENU and BACK touch keys, because for these keys is simpler to recognize a bad interrupt or an invalid key press, instead it's disabled for incoming HOME key (read the next howto infos to enable it).
I also developed a new app to better manage the filtering status and the filtering parameters customization, you can find it on this thread:
Phantom Key Presses Filter Manager
How to enable/disable the feauture and customize the filtering parameters:
The new device module allows to show the number of ignored key presses and to customize the filtering parameters by means of a sysfs interface, at the following system path: /sys/class/misc/phantom_kp_filter
The interface exposes these files:
home_enabled: show/edit the enable status of the phantom HOME key presses filtering (0 = disabled and 1 = enabled, disabled by default)
home_allowed_irqs: show/edit the allowed max number of incoming interrupts to consider a HOME key press as valid (from 1 to 32, default = 4), a lower value allows to have a more aggressive filtering, instead a higher value allows to have a more permissive filtering
home_report_wait: show/edit the wait time in ms before report the collected HOME key presses (from 5 to 25 ms, default = 12 ms), the key presses during this wait time are collected and reported only if the system received a number of interrupts less than or equal to the allowed max number of incoming interrupts (home_allowed_irqs parameter)
home_ignored_kp: show the ignored possible phantom HOME key presses
menuback_enabled: show/edit the enable status of the phantom MENU and BACK key presses filtering (0 = disabled, 1 = enabled, enabled by default)
menuback_interrupt_checks: show/edit the number of interrupt checks to be performed for the incoming MENU and BACK key presses (from 1 to 10, default = 10), a lower value is more permissive, a higher value securely avoids most of the bad interrupts
menuback_first_err_wait: show/edit the time in ms to wait after the first error on MENU or BACK keys if there are many invalid key errors in rapid sequence (from 50 to 1000 ms, default = 500 ms), the default value is optimal and well tested
menuback_last_err_wait: show/edit the time in ms to wait after the last error on MENU or BACK keys if there are many invalid key errors in rapid sequence (from 50 to 1000 ms, default = 100 ms), the default value is optimal and well tested
menuback_ignored_kp: show the ignored possible phantom MENU and BACK key presses
version: show the module version
To change the filtering parameters:

CPU voltage control VDD sys interface
This feature allows to customize the voltage assumed by each cpu scaling frequency.
It could be useful if you'd like to decrease one or more voltages for battery saving purposes (undervolting), or to increase/adjust them to prevent phone freezes (overvolting).
How to customize the voltages:
1) By downloading and using Trickster MOD or IncrediControl and changing the voltages table inside the SVS tab
2) By using customized init.d scripts (the custom values will be always restored after a reboot, if you don't format the system partition)
- Download one of the script named 01vdd_levels*
- If the file has been saved with .txt extension (stock browser), rename it by removing the .txt extension
- Edit the file by setting your customized voltages, where each line has this syntax
Code:
echo "[I][B][COLOR="Blue"]cpu_freq_HZ[/COLOR][/B][/I] [I][COLOR="SeaGreen"][B]mV[/B][/COLOR][/I]" > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels
cpu_freq_HZ is the cpu frequency in Hz you'd like to change
mV is the voltage you want to set
For example, the following line means that when the cpu frequency is 1516800 Hz = 1516 MHz, the voltage used will be 1175 mV
Code:
echo "1516800 1175" > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels
- Copy the new file inside /etc/init.d
- Give the rwxr-xr-x permissions to the file (read, write, execution for owner, read and execution for group users, read and execution for others)
- Reboot
3) By using Terminal Emulator (note that the values you set will be lost after a reboot/shutdown)
- Open Terminal Emulator
- Run these commands
Code:
su
# Run a command for each cpu frequency voltage you'd like to change
echo "[I][B][COLOR="Blue"]cpu_freq_HZ[/COLOR][/B][/I] [I][COLOR="SeaGreen"][B]mV[/B][/COLOR][/I]" > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels
cpu_freq_HZ is the cpu frequency in Hz you'd like to change
mV is the voltage you want to set
For example, the following line means that when the cpu frequency is 1516800 Hz = 1516 MHz, the voltage used will be 1175 mV
Code:
echo "1516800 1175" > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels
Alternative Extreme Undervolted (ExUV) settings
If after overclocking your I9001 you noticed some freezes when on ExUV kernel builds, you may use an alternative extremely undervolted setting with the init.d script you can find here: 01vdd_levels_alt_exuv
- Download the script
- If the file has been saved with .txt extension (stock browser), rename it by removing the .txt extension
- Copy the new file inside /etc/init.d
- Give the rwxr-xr-x permissions to the file (read, write, execution for owner, read and execution for group users, read and execution for others)
- Reboot
Customized vibration intensity
This feature has been developed by CastagnaIT and allows to set a customized vibration intensity (121 is the default stock value).
It could be useful if you don't like the stock vibration intensity and you'd like to have a lower / stronger vibration.
The setting will affect the haptic feedback and the notification vibration intensity.
How to set a customized vibration intensity:
1) By using the related setting inside System->Advanced->Vibration (only on CM 10 Beta 4 and next releases)
2) By using a customized init.d script (the custom value will be always restored after a reboot, if you don't format the system partition)
- Download the script named 10vibetonz
- If the file has been saved with .txt extension (stock browser), rename it by removing the .txt extension
- Edit the file by setting your preferred vibration intensity (the downloaded script will set the vibration intensity to 70)
- Copy the new file inside /etc/init.d
- Give the rwxr-xr-x permissions to the file (read, write, execution for owner, read and execution for group users, read and execution for others)
- Reboot
3) By directly editing the file /sys/class/vibetonz/immDuty/pwmvalue_intensity (the value you set will be lost after a reboot/shutdown)
4) By using Terminal Emulator (note that set values will be lost after a reboot/shutdown)
- Open Terminal Emulator
- Run these commands (changing the intensity value = 70 with the preferred one)
Code:
su
echo 70 > /sys/class/vibetonz/immDuty/pwmvalue_intensity
Backlight Notification V10 (BLNv10)
This feature allows to notify you of missing calls, messages, emails, etc... by lighting up or blinking the Menu and Back buttons.
With BLNv10 enabled you don't need to unlock the screen to see if you have new notifications.
How to configure the BLNv10:
1) By using new AriesParts (Advanced Settings) or by downloading and using BLN Control Free, BLN Control Pro or NsTools
2) By directly editing the file /sys/class/misc/backlightnotification/enabled and setting 1 to enable the feature, 0 to disable it (note that set value will be lost after a reboot/shutdown)
3) By using Terminal Emulator (note that set value will be lost after a reboot/shutdown)
- Open Terminal Emulator
- Run this command to enable the feature
Code:
su
echo 1 > /sys/class/misc/backlightnotification/enabled
- Run, instead, this command to disable the feature
Code:
su
echo 0 > /sys/class/misc/backlightnotification/enabled
Work in progress (init.d, blinking and other settings)...
Force Fast Charge
This feature allows you to force AC charging for any charger that is detected as USB (eg. PC USB ports, USB Car Chargers) and pull the full current the charger can support, in such a way as to speed up the time required for a complete battery recharge.
By enabling this feature, the USB / ADB data transfers will be disabled (security limitation to protect your data).
How to enable/disable the Force Fast Charge:
1) By using the related setting inside System->Advanced->Force Fast Charge (only on CM 10 Beta 3 and next releases)
2) By downloading and using Trickster MOD or IncrediControl or NsTools
2) By directly editing the file /sys/kernel/fast_charge/force_fast_charge and setting 1 to enable the force charge, 0 to disable it (note that set value will be lost after a reboot/shutdown)
3) By using Terminal Emulator (note that set value will be lost after a reboot/shutdown)
- Open Terminal Emulator
- Run this command to enable the force fast charge feature
Code:
su
echo 1 > /sys/kernel/fast_charge/force_fast_charge
- Then, when you want to restore the normal status, run this command to disable the force fast charge feature
Code:
su
echo 0 > /sys/kernel/fast_charge/force_fast_charge
4) By using a customized init.d script, but I don't recommend it because you have to remember to disable the feature every time you want to connect your device to a pc for data transfering after every reboot
Battery life extender (BLX)
This feature has been developed by Ezekeel and allows to set a customized battery charging limit (100% is the default stock value, if you want, you can set a lower value).
As Ezekeel said, it is commonly accepted that both very low and very high charge states accelerate the degradation of the battery capacity (that is why you should store Li-Ion batteries at around 40% charge).
If you set a charging limit equal to 100, this feature will be disabled.
How to activate this feature and set a customized charging limit:
1) By downloading and using Trickster MOD or NsTools by setting the customized battery life extender charging limit
2) By using a customized init.d script (the custom value will be always restored after a reboot, if you don't format the system partition)
- Download the script named 15blx
- If the file has been saved with .txt extension (stock browser), rename it by removing the .txt extension
- Edit the file by setting your preferred charging limit (the downloaded script will set the charging limit to 95%)
- Copy the new file inside /etc/init.d
- Give the rwxr-xr-x permissions to the file (read, write, execution for owner, read and execution for group users, read and execution for others)
- Reboot
3) By directly editing the file /sys/class/misc/batterylifeextender/charging_limit (the value you set will be lost after a reboot/shutdown)
4) By using Terminal Emulator (note that set value will be lost after a reboot/shutdown)
- Open Terminal Emulator
- Run these commands (changing the charging limit = 95 with the preferred one)
Code:
su
echo 95 > /sys/class/misc/batterylifeextender/charging_limit
LowMemoryKiller
The LowMemoryKiller driver is used to kill a selected process and free the memory when it is under one of the defined thresholds.
The tuning of the driver could be achieved by means of two parameters exposed by the kernel module via sysfs interface:
- /sys/module/lowmemorykiller/parameters/minfree
This file includes a comma separated array of the threshold numbers for minfree memory size (in page units).
The parameter value set for K^Kernel is "2048,4096,6656,9216,14336,19456".
- /sys/module/lowmemorykiller/parameters/adj
This file includes the comma separated array of oomadj factors, if the corresponding minfree threshold has been reached, one of the process with an oomadj greater than this number will be killed.
The oomadj factor is a property associated to each process, its value is in a range from -17 to +15, the processes with a higher oomadj factor will be the first to be killed when a specific minfree threshold has been reached.
The parameter value set for K^Kernel is "0,20,50,100,250,500".
Frandom - Fast Random Generator
As Eli Billauer (the creator of this module) said, Frandom is a Linux kernel random number generator, which is 10-50 times faster than what you get from Linux built-in /dev/urandom. And it uses very little (/dev/frandom) or none (/dev/erandom) of the kernel's entropy pool, so it is very useful for applications that require a handy source for lots of random data.
How to test if frandom builtin module is correctly working:
- Download the script named frandom_test.sh
- Using your preferred file explorer, copy the file inside the folder /data/local of your device
- Give the rwxr-xr-x permissions to the file (read, write, execution for owner, read and execution for group users, read and execution for others)
- Open Terminal Emulator
- Run this command
Code:
/data/local/frandom_test.sh
You should see a result similar to this one:
If the urandom tests take more than 1 or 2 seconds and are more different than related frandom tests, then the random number generation is not fully optimized for your currently used kernel...
How to disable / re-enable the redirection to frandom module during boot process:
By using Terminal Emulator:
- Run these commands to create the flag file and disable Frandom redirection:
Code:
su
touch /data/frandom_disabled
- Or run these commands to delete the flag file and re-enable Frandom redirection:
Code:
su
rm /data/frandom_disabled
The change will take effect after a reboot.
RAM Console
This feature is useful expecially for development and debugging purposes, when occurs kernel panic / unexpected shutdowns or reboots. Pratically, the kernel messages are also stored inside a little RAM portion and restored during reboot after a kernel panic, inside the file /proc/last_kmsg.
Dynamic FSync
This feature has been developed by Faux123 and allows to dynamically manage the synchronous writes performed on file system (FSync).
It uses asynchronous writes when the screen is on, instead of synchronous writes, to have better performance and a slightly lower battery drain, while when the screen is off the synchronous writes are re-enabled to flush all the outstanding writes and prevent possible data loss.
How to enable/disable the Dynamic FSync (default enabled):
1) By downloading and using Trickster MOD
2) By directly editing the file /sys/kernel/dyn_fsync/Dyn_fsync_active and setting 1 to enable the dynamic fsync, 0 to disable it (note that set value will be lost after a reboot/shutdown)
3) By using Terminal Emulator (note that set value will be lost after a reboot/shutdown)
- Open Terminal Emulator
- Run this command to disable the dynamic fsync feature
Code:
su
echo 0 > /sys/kernel/dyn_fsync/Dyn_fsync_active
- Or run this command to re-enable the dynamic fsync feature
Code:
su
echo 1 > /sys/kernel/dyn_fsync/Dyn_fsync_active
Dynamic dirty page writebacks
This feature has been developed by me and allows to dynamically manage the dirty page writebacks with two different intervals, one when the screen is on and another when the screen is off.
It is based on a commit of Francisco Franco, but instead of using hard coded values and of disabling at all the dirty page writebacks while the screen is on (possibility of data loss), I preferred to use a customizable higher dirty page writebacks interval (15 seconds) than the default one (5 seconds) while the screen is on and a customizable default interval (5 seconds) when the screen is off.
By using a higher interval we have better performance and less battery consumption, with a very low risk of data loss.
How to customize the dynamic dirty page writebacks feature (default enabled):
Three new procfs parameters are exposed inside /proc/sys/vm path:
- dynamic_dirty_writeback is the activation status of this feature, set 1 to enable it, set 0 to disable it and use the standard behaviour
- dirty_writeback_active_centisecs is the interval for the dirty page writebacks when the system is active (screen on), the default value is 1500 centisecs (15 seconds)
- dirty_writeback_suspend_centisecs is the interval for the dirty page writebacks when the system is suspended (screen off), the default value is 500 centisecs (5 seconds)
In my kernel builds, during boot, I set other customized values:
- an interval of 30 seconds while the screen is on
- an interval of 10 seconds when the screen is off
1) By directly editing one of the file written above inside /proc/sys/vm and setting the preferred value (note that set value will be lost after a reboot/shutdown)
2) By using Terminal Emulator (note that set value will be lost after a reboot/shutdown)
- Open Terminal Emulator
- Run this command to disable the dynamic dirty page writebacks feature
Code:
su
echo 0 > /proc/sys/vm/dynamic_dirty_writeback
- Or run this command to re-enable the dynamic dirty page writebacks feature
Code:
su
echo 1 > /proc/sys/vm/dynamic_dirty_writeback
- Run this command to set customize the two intervals (30 seconds while the screen is on, 10 seconds when the screen is off)
Code:
su
echo "3000" > /proc/sys/vm/dirty_writeback_active_centisecs
echo "1000" > /proc/sys/vm/dirty_writeback_suspend_centisecs
Special features and sysfs settings (Part 2):
Timer slack controller and dynamic management of the minimal timer slack value
The timer slack controller is a feature developed by Kirill Shutemov and it allows to set the minimal timer slack value for every process contained within a control group (cgroup).
A timer slack allows the kernel to manage processes wakeup requests at some future time.
Thanks to this feature, the kernel can set a specific timer slack for the involved processes, minimizing the number of wakeups and allowing a lower system's power consumption.
For further info: Timer slack for slacker developers
I also implemented a new feature in addition to the above one that allows the dynamic management of the minimal timer slack value.
So, it's possible to use different minimal timer slack value when the system is active and when has been suspended.
How to customize the dynamic timer slack controller feature:
Three new cgroup parameters are exposed inside each processes hierarchy contained in /dev/cpuctl path:
- timer_slack.min_slack_ns is the timer slack used when the system is active for the current processes hierarchy
- timer_slack.min_slack_suspend_ns is the timer slack used when the system is suspended for the current processes hierarchy
- timer_slack.effective_slack_suspend_ns is the timer slack currently used
At the moment, the values chosen and used by K^Kernel are the following:
- core processes (/dev/cpuctl), 0 ns when the system is active, 50000 ns when the system is suspended
- foreground apps/processes (/dev/cpuctl/apps), 0 ns when the system is active, 250000 ns when the system is suspended
- background non interactive apps/processes (/dev/cpuctl/apps/bg_non_interactive), 100000000 ns when the system is active, 250000000 ns when the system is suspended
1) By directly editing one of the file written above inside /dev/cpuctl and inside each hierarchy subfolder, by setting the preferred value (note that set value will be lost after a reboot/shutdown)
2) By using Terminal Emulator (note that set value will be lost after a reboot/shutdown)
- Open Terminal Emulator
- Run these commands to set the minimal timer slack for generic and core apps/processes
Code:
su
echo 0 > /dev/cpuctl/timer_slack.min_slack_ns
echo 50000 > /dev/cpuctl/timer_slack.min_slack_suspend_ns
- Run these commands to set the minimal timer slack for apps/processes in foreground
Code:
su
echo 0 > /dev/cpuctl/apps/timer_slack.min_slack_ns
echo 100000 > /dev/cpuctl/apps/timer_slack.min_slack_suspend_ns
- Run these commands to set the minimal timer slack for apps/processes in background and non interactive
Code:
su
echo 100000000 > /dev/cpuctl/apps/bg_non_interactive/timer_slack.min_slack_ns
echo 250000000 > /dev/cpuctl/apps/bg_non_interactive/timer_slack.min_slack_suspend_ns
LowMemoryKiller management of not killable processes
This feature allows to define processes and system processes white-lists filled with the preferred process names and to not be killed by lowmemorykiller, unless it is absolutely necessary.
This feature exposes four new lowmemorykiller parameters:
- donotkill_proc, is the flag to enable / disable this feature for the processes chosen by the user
- donotkill_sysproc, is the flag to enable / disable this feature for the system processes chosen by the user
- donotkill_proc_names, is the list of process names (comma separated) chosen by the user to be preserved from killing
- donotkill_sysproc_names, is the list of user system process names (comma separated) chosen by the user to be preserved from killing
When the lowmemorykiller needs to free ram, it will first kill the processes not included inside the two process name lists chosen by the user.
If there are no more standard killable processes, then it will be necessary to kill one of the processes included inside one of the two white-lists, to prevent system hangs, slowdowns, etc.
How to customize the white lists of processes to preserve from killing:
On K^Kernel the feature is enabled by default and the provided processes white lists are the following:
- donotkill_proc_names = "com.cyanogenmod.trebuchet,com.anddoes.launcher,com.teslacoilsw.launcher,org.adwfreak.launcher,gtp.nextlauncher,android.inputmethod.latin,com.touchtype.swiftkey"
this means that Trebuchet Launcher, Apex Launcher, Nova Launcher, ADW Launcher, Next Launcher, stock keyboard and SwiftKey keyboard will be preserved from killing
- donotkill_sysproc_names = "android.process.acore,com.android.phone,com.bel.android.dspmanager"
this means that the system process, the phone process and DSP Manager will be preserved from killing
1) By using a customized init.d script (the custom value will be always restored after a reboot, if you don't format the system partition)
- Download the script named 80dnkp
- If the file has been saved with .txt extension (stock browser), rename it by removing the .txt extension
- Edit the file by setting your preferred status and processes list
- Copy the new file inside /etc/init.d
- Give the rwxr-xr-x permissions to the file (read, write, execution for owner, read and execution for group users, read and execution for others)
- Reboot
2) By directly editing the files inside /sys/module/lowmemorykiller/parameters (note that set values will be lost after a reboot/shutdown)
3) By using Terminal Emulator (note that set values will be lost after a reboot/shutdown)
- Open Terminal Emulator
- Run these commands if you want to enable the feature
Code:
# To enable this feature for the processes chosen by the user
echo 1 > /sys/module/lowmemorykiller/parameters/donotkill_proc
# To enable this feature for the system processes chosen by the user
echo 1 > /sys/module/lowmemorykiller/parameters/donotkill_sysproc
- Run these commands if you want to disable the feature
Code:
# To disable this feature for the processes chosen by the user
echo 0 > /sys/module/lowmemorykiller/parameters/donotkill_proc
# To disable this feature for the system processes chosen by the user
echo 0 > /sys/module/lowmemorykiller/parameters/donotkill_sysproc
- Run this command if you want to add, for example, Trebuchet Launcher (CM default launcher) and the default keyboard to the processes white list
Code:
echo "com.cyanogenmod.trebuchet,android.inputmethod.latin" > /sys/module/lowmemorykiller/parameters/donotkill_proc_names
- Run this command if you want to add, for example, the system process, the phone process and DSP Manager to the system processes white list
Code:
echo "android.process.acore,com.android.phone,com.bel.android.dspmanager" > /sys/module/lowmemorykiller/parameters/donotkill_sysproc_names
ZRAM module
As explained on Wikipedia, this feature, provided in this kernel as a built-in module, increases performance by avoiding paging on disk and instead uses a compressed block device in RAM in which paging takes place until it is necessary to use the swap space on the hard disk drive.
In few words, the memory pages no more used and so to be swapped are sent to zRam device blocks, compressed and stored in memory instead of disk allowing better performance and also lower memory usage, on the other hand, a little higher amount of cpu is needed to perform compression and decompression of memory pages.
Since we have a device with a low amount of free memory, this feature could be useful to have more free ram.
You can enable it inside System Settings -> Performance -> Memory Management -> zRam by choosing your preferred compression option (18% is the default one).
Work in progress...
FAQ - Frequently asked questions:
Q: What are the differences between EXUV and UV kernel versions?
A: The EXUV kernel versions have extremely undervolted settings for the cpu frequencies, they allows to have a very low battery drain, instead the UV kernel versions have undervolted settings a bit higher than EXUV versions, but always lower than stock kernel settings.
The EXUV kernel versions could give some problems (freezes, shutdowns, huge lags) on some devices because the cpu doesn't support too low voltage settings.
For a lower battery consumption, I suggest you to try EXUV versions first and to switch to UV versions only if you encounter one of the above mentioned problems.
Q: For kernel v1.8 and before, what are the differences between 398MB, 406MB and 416MB versions?
A: 398MB, 406MB and 416MB kernel versions have different free ram available for user space, with a higher free ram your device will work better with heavy apps, many concurrently used apps, heavy games, etc.
- 398MB versions have the same amount of free ram than stock kernels, they are more stable, everything is fully working, but you could have some slowdowns with apps that require a high amount of free memory.
- 406MB versions have additional 8 MB of free ram than stock kernels, they are suitable for the users that use the device primarly for calls, messages, simple apps and simple games. The camera, video recording (both 480p and 720p modes) and video playback are fully working.
- 416MB versions have additional 18 MB of free ram than stock kernels, they are suitable for the users that use the device also with heavy apps, various concurrently used apps and games. The camera, video recording (both 480p and 720p modes) and video playback are fully working.
Q: Why should I deactivate KSM (Kernel Samepage Merge)?
A: KSM (Kernel Samepage Merge), let us save a bit of RAM space used by kernel (max 10MB during my analysis) by merging duplicated memory pages used by different processes, but it has also some performance impacts, since it uses CPU time to perform those memory scanning and merging operations.
So, in few words, it could free up a bit of RAM, but sometimes keeps the CPU busy to complete its work.
After introducing the dynamic allocation of MM ION and PMEM ADSP heaps, KSM could cause issues while trying to use camera or camcorder and playing HW/HW+ videos.
This is due to the impossibility to allocate one or more memory pages that have been merged by KSM inside the memory area reserved for dynamic allocations for MM ION or PMEM ADSP heaps through CMA (Contiguous Memory Allocator).
I'm looking for a solution for this "incompatibility", but at the moment the tried changes didn't work.
So, as a workaround, don't activate KSM until we find a fully working solution, since the RAM freed by dynamic allocation is surely higher than KSM freed RAM without any performance impact during normal usage.
The option can be deactivated inside Settings -> Performance -> Memory management -> Kernel samepage merging.
Q: How can I get the Performance and Developer Options entries inside Settings menu?
A: Go inside Settings -> About Phone -> Scroll down and tap 7 times on Build number (it's an Easter Egg).
Q: How can I get the log after an unexpected shutdown / reboot?
A: After an unexpected shutdown / reboot of the device, if the problem may be kernel related, you should have the /proc/last_kmsg, if so, send me that log and I'll check it to find the possible cause of the problem.
Q: How can I get the logs when I encounter strange system issues while it's running?
A: Check first if the problems could be related to an app you're using and if you changed something in the last days before facing those issues.
If the problem started after installing the kernel, then let me have you logcat and dmesg:
- Open Terminal Emulator and execute these commands:
Code:
su
dmesg > /sdcard/dmesg.txt
locat -v time -d > /sdcard/logcat.txt
- Open you preferred file manager and go inside the internal sd card partition /sdcard
- Send me the dmesg.txt and logcat.txt files, if you want zip them first
Q: How can I mount a shared Windows folder with CIFS module?
1) By using Terminal Emulator
Code:
mount -o unc=\\\\[COLOR="DarkGreen"][I]ip[/I][/COLOR]\\[COLOR="Blue"][I]share[/I][/COLOR],noserverino,username=[I][COLOR="DarkOrange"]user[/COLOR][/I],password=[I][COLOR="Lime"]password[/COLOR][/I] -t cifs //[COLOR="DarkGreen"]ip[/COLOR]/[COLOR="Blue"]share[/COLOR] [I][COLOR="DarkSlateGray"]/mnt/cifs[/COLOR][/I]
2) Downloading and using CifsManager and configuring the new share as follow:
- Share Path = ip/share
- Mount Point = /mnt/cifs/share
- Username = username
- Password = password
- Options = unc=\\\\ip\\share,noserverino
Where:
ip is the ip address of your pc where the folder is shared
share is the shared folder name
user is the user name that can access the shared folder
password is the user password
/mnt/cifs is the mount point (must be created if you'd like to use the command approach with Terminal Emulator)
Reserved, just in case...
great - was waiting for this, christopher^^ Just installing 380MB ExUV
Edit: had problems /w 380MB during boot (scratchy bootanimation, stuck at boot) - now starting with 370MB which starts up fine.

Awesome! Thanks a ton, Christopher!
I always use the 370 MB version of your kernels so I can't confirm the above problems. No problem installing the 370 MB ExUV kernel though. Feels uber-smooth!
Wow amazing work Christopher! 370MB Ram available, its just the same as I used before. I can feel that performance boost right now. You are doing a great job. Keep working.

Thanks,
I'll better check the memory allocations for 380MB configuration and surely change them.
This could happen after flashing the kernel with 380MB, it happened to me one time, simply shutdown the phone and reboot, it shouldn't happen again...
Uploaded new 378MB memory configuration
At the moment, 378MB is the best maximum amount of ram I can get to prevent screen glitches and issues during boot, without sacrificing camera, camcorder at 480p, video playback + recording, audio.
I uploaded the new builds, let me know how they works.
Thanks again!
Great work Chris You should have thousands of thanks Thank you

A thing that I can't consider it a problem is that Antutu Benchmark isn t launching tried on 378 and 370 exUV verions... Can it be the exUV who is blocking this!? Anyone with a working Antutu Bench'!? Must say that on stock worked before . Is the ADC Team providing stock kernel for v1.0 ION Rom as said!?

Wifi works great with 370 mb ( exUV ) , but yes ...Antuntu don´t work. why so?

Have you tried activating it from quick settings/status bar? Power widget? or straight from WiFi menu?
I would recommend after a restart from WiFi menu in settings.
Antutu doesnt work. It forcly close itself. 370Mb exUv
WiFi Problems
Hi Christopher,
i still haven't tested k^Kernel because i'm testing some other things, but when i read about Wifi problems it remembers be of the problems we encountered when you provide your newest kernel for "older ROMs". Because i'm not that skilled i cite Erik:
So, the thing is that new ROM's are using inline kernel building and not prebuit (like I used for the latest Liquid Smooth build). When prebuilt kernel was used, the libs were pushed to /lib/modules. Now, after we updated to inline kernel building the libs are pushed and read from /system/lib/modules.
So, I compiled a kernel the old way like it would have been prebuilt so it pushes and reads the modules from /lib/modules. This should match the Liquid Smooth ROM.

Could this be a problem with your newest build and the ION Rom too ? Just an assumtion.
Cheers
Rhonin

After flashing the 380 MB exUV variant of this kernel i can confirm that WiFi is working - So everything seems to be fine up to now THX a lot

Kernel Special Features: Customized kernel 3.4.x for KK 4.4 rom (CM 11.0 and derivatives) with ION memory allocations
Version Information
Status: Stable
Current Stable Version: v5.0
Stable Release Date: 2015-02-09
Created 2013-12-22
Last Updated 2015-06-08
Special features and sysfs settings (Part 1):
Here you can find some useful scripts that can be used with the following described features:
Scripts
Phantom Key Presses filter
This feature is an attempt to workaround a well known hardware bug of some Samsung devices.
Pratically, the high activity of the radio hardware, in particular the antenna, could cause interference on Melfas chip, which is located very close to the antenna.
This interference could induce bad interrupts that are seen by the chip as possible HOME, MENU or BACK key presses.
These phantom key presses are happening expecially in 2G mode.
The solution includes a new device module (phantom_kp_filter), which also allows the filtering parameters customization, and various changes to cypress-touchkey and pmic8xxx-keypad modules.
The phantom key presses filtering is enabled by default for incoming MENU and BACK touch keys, because for these keys is simpler to recognize a bad interrupt or an invalid key press, instead it's disabled for incoming HOME key (read the next howto infos to enable it).
I also developed a new app to better manage the filtering status and the filtering parameters customization, you can find it on this thread:
Phantom Key Presses Filter Manager
How to enable/disable the feauture and customize the filtering parameters:
The new device module allows to show the number of ignored key presses and to customize the filtering parameters by means of a sysfs interface, at the following system path: /sys/class/misc/phantom_kp_filter
The interface exposes these files:
home_enabled: show/edit the enable status of the phantom HOME key presses filtering (0 = disabled and 1 = enabled, disabled by default)
home_allowed_irqs: show/edit the allowed max number of incoming interrupts to consider a HOME key press as valid (from 1 to 32, default = 4), a lower value allows to have a more aggressive filtering, instead a higher value allows to have a more permissive filtering
home_report_wait: show/edit the wait time in ms before report the collected HOME key presses (from 5 to 25 ms, default = 12 ms), the key presses during this wait time are collected and reported only if the system received a number of interrupts less than or equal to the allowed max number of incoming interrupts (home_allowed_irqs parameter)
home_ignored_kp: show the ignored possible phantom HOME key presses
menuback_enabled: show/edit the enable status of the phantom MENU and BACK key presses filtering (0 = disabled, 1 = enabled, enabled by default)
menuback_interrupt_checks: show/edit the number of interrupt checks to be performed for the incoming MENU and BACK key presses (from 1 to 10, default = 10), a lower value is more permissive, a higher value securely avoids most of the bad interrupts
menuback_first_err_wait: show/edit the time in ms to wait after the first error on MENU or BACK keys if there are many invalid key errors in rapid sequence (from 50 to 1000 ms, default = 500 ms), the default value is optimal and well tested
menuback_last_err_wait: show/edit the time in ms to wait after the last error on MENU or BACK keys if there are many invalid key errors in rapid sequence (from 50 to 1000 ms, default = 100 ms), the default value is optimal and well tested
menuback_ignored_kp: show the ignored possible phantom MENU and BACK key presses
version: show the module version
To change the filtering parameters:
1) By downloading and using my new app PkfManager
2) By using a customized init.d script (the custom value will be always restored after a reboot, if you don't format the system partition)
- Download the script named 05pkf_alt
- If the file has been saved with .txt extension (stock browser), rename it by removing the .txt extension
- Edit the file by setting your preferred filtering parameters (the downloaded script has the default filtering parameter values and enables the phantom HOME key presses filtering)
- Copy the new file inside /etc/init.d
- Give the rwxr-xr-x permissions to the file (read, write, execution for owner, read and execution for group users, read and execution for others)
- Reboot
3) By directly editing the files inside /sys/class/misc/phantom_kp_filter (the values you set will be lost after a reboot/shutdown)
4) By using Terminal Emulator (note that set values will be lost after a reboot/shutdown)
- Open Terminal Emulator
- Run these commands
Code:
su
echo [COLOR="Blue"][I]value[/I][/COLOR] > /sys/class/misc/phantom_kp_filter/[COLOR="Green"][I]parameter_name[/I][/COLOR]
where value is the value you want to set and parameter_name is one of the previously described editable parameters
For example, these commands will enable phantom HOME key presses filtering:
Code:
su
echo 1 > /sys/class/misc/phantom_kp_filter/home_enabled
To show the number of ignored key presses (possible phantom key presses):
1) By directly opening the files /sys/class/misc/phantom_kp_filter/home_ignored_kp and /sys/class/misc/phantom_kp_filter/menuback_ignored_kp
2) By using Terminal Emulator
- Open Terminal Emulator
- Run these commands
Code:
su
cat /sys/class/misc/phantom_kp_filter/home_ignored_kp
cat /sys/class/misc/phantom_kp_filter/menuback_ignored_kp
Customizable timeout of touchkeys backlight after press
This feature allows to set a customized timeout of touchkeys backlight after a key press or touchscreen press. The default value is 1600 ms.
How to set the timeout of touchkeys backlight:
1) By using the related setting inside System -> Advanced -> Backlight Timeout
2) By using a customized init.d script (the custom value will be always restored after a reboot, if you don't format the system partition)
- Download the script named 20backlight_timeout
- If the file has been saved with .txt extension (stock browser), rename it by removing the .txt extension
- Edit the file by setting your preferred timeout (the downloaded script will set the status to 0 = disabled)
- Copy the new file inside /etc/init.d
- Give the rwxr-xr-x permissions to the file (read, write, execution for owner, read and execution for group users, read and execution for others)
- Reboot
3) By directly editing the file /sys/class/misc/notification/bl_timeout (the value you set will be lost after a reboot/shutdown)
4) By using Terminal Emulator (note that set values will be lost after a reboot/shutdown)
- Open Terminal Emulator
- Run these commands to set the timeout of touchkeys backlight to 1000 ms (1 second)
Code:
su
echo 1000 > /sys/class/misc/notification/bl_timeout
Customizable activation status of touchkeys backlight on touchscreen press
This feature allows to enable/disable the touchkeys backlight after a touchscreen press.
How to set the status of touchkeys backlight on touchscreen press:
1) By using the related setting inside System -> Advanced -> Backlight on Touchscreen Press
2) By using a customized init.d script (the custom value will be always restored after a reboot, if you don't format the system partition)
- Download the script named 25touchlight_status
- If the file has been saved with .txt extension (stock browser), rename it by removing the .txt extension
- Edit the file by setting your preferred status(the downloaded script will set the status to 0 = disabled)
- Copy the new file inside /etc/init.d
- Give the rwxr-xr-x permissions to the file (read, write, execution for owner, read and execution for group users, read and execution for others)
- Reboot
3) By directly editing the file /sys/class/misc/notification/touchlight_enabled (the value you set will be lost after a reboot/shutdown)
4) By using Terminal Emulator (note that set values will be lost after a reboot/shutdown)
- Open Terminal Emulator
- Run these commands to disable the touchkeys backlight on touchscreen press
Code:
su
echo 0 > /sys/class/misc/notification/touchlight_enabled
- Or run these commands to enable the touchkeys backlight on touchscreen press
Code:
su
echo 1 > /sys/class/misc/notification/touchlight_enabled
CPU voltage control VDD sys interface
This feature allows to customize the voltage assumed by each cpu scaling frequency.
It could be useful if you'd like to decrease one or more voltages for battery saving purposes (undervolting), or to increase/adjust them to prevent phone freezes (overvolting).
How to customize the voltages:
1) By downloading and using Trickster MOD or IncrediControl and changing the voltages table inside the SVS tab
2) By using customized init.d scripts (the custom values will be always restored after a reboot, if you don't format the system partition)
- Download one of the script named 01vdd_levels*
- If the file has been saved with .txt extension (stock browser), rename it by removing the .txt extension
- Edit the file by setting your customized voltages, where each line has this syntax
Code:
echo "[I][B][COLOR="Blue"]cpu_freq_HZ[/COLOR][/B][/I] [I][COLOR="SeaGreen"][B]mV[/B][/COLOR][/I]" > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels
cpu_freq_HZ is the cpu frequency in Hz you'd like to change
mV is the voltage you want to set
For example, the following line means that when the cpu frequency is 1516800 Hz = 1516 MHz, the voltage used will be 1175 mV
Code:
echo "1516800 1175" > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels
- Copy the new file inside /etc/init.d
- Give the rwxr-xr-x permissions to the file (read, write, execution for owner, read and execution for group users, read and execution for others)
- Reboot
3) By using Terminal Emulator (note that the values you set will be lost after a reboot/shutdown)
- Open Terminal Emulator
- Run these commands
Code:
su
# Run a command for each cpu frequency voltage you'd like to change
echo "[I][B][COLOR="Blue"]cpu_freq_HZ[/COLOR][/B][/I] [I][COLOR="SeaGreen"][B]mV[/B][/COLOR][/I]" > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels
cpu_freq_HZ is the cpu frequency in Hz you'd like to change
mV is the voltage you want to set
For example, the following line means that when the cpu frequency is 1516800 Hz = 1516 MHz, the voltage used will be 1175 mV
Code:
echo "1516800 1175" > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels
Alternative Extreme Undervolted (ExUV) settings
If after overclocking your I9001 you noticed some freezes when on ExUV kernel builds, you may use an alternative extremely undervolted setting with the init.d script you can find here: 01vdd_levels_alt_exuv
- Download the script
- If the file has been saved with .txt extension (stock browser), rename it by removing the .txt extension
- Copy the new file inside /etc/init.d
- Give the rwxr-xr-x permissions to the file (read, write, execution for owner, read and execution for group users, read and execution for others)
- Reboot
Customized vibration intensity
This feature has been developed by CastagnaIT and allows to set a customized vibration intensity (121 is the default stock value).
It could be useful if you don't like the stock vibration intensity and you'd like to have a lower / stronger vibration.
The setting will affect the haptic feedback and the notification vibration intensity.
How to set a customized vibration intensity:
1) By using the related setting inside System->Advanced->Vibration (only on CM 10 Beta 4 and next releases)
2) By using a customized init.d script (the custom value will be always restored after a reboot, if you don't format the system partition)
- Download the script named 10vibetonz
- If the file has been saved with .txt extension (stock browser), rename it by removing the .txt extension
- Edit the file by setting your preferred vibration intensity (the downloaded script will set the vibration intensity to 70)
- Copy the new file inside /etc/init.d
- Give the rwxr-xr-x permissions to the file (read, write, execution for owner, read and execution for group users, read and execution for others)
- Reboot
3) By directly editing the file /sys/class/vibetonz/immDuty/pwmvalue_intensity (the value you set will be lost after a reboot/shutdown)
4) By using Terminal Emulator (note that set values will be lost after a reboot/shutdown)
- Open Terminal Emulator
- Run these commands (changing the intensity value = 70 with the preferred one)
Code:
su
echo 70 > /sys/class/vibetonz/immDuty/pwmvalue_intensity
Backlight Notification V10 (BLNv10)
This feature allows to notify you of missing calls, messages, emails, etc... by lighting up or blinking the Menu and Back buttons.
With BLNv10 enabled you don't need to unlock the screen to see if you have new notifications.
How to configure the BLNv10:
1) By using new AriesParts (Advanced Settings) or by downloading and using BLN Control Free, BLN Control Pro or NsTools
2) By directly editing the file /sys/class/misc/backlightnotification/enabled and setting 1 to enable the feature, 0 to disable it (note that set value will be lost after a reboot/shutdown)
3) By using Terminal Emulator (note that set value will be lost after a reboot/shutdown)
- Open Terminal Emulator
- Run this command to enable the feature
Code:
su
echo 1 > /sys/class/misc/backlightnotification/enabled
- Run, instead, this command to disable the feature
Code:
su
echo 0 > /sys/class/misc/backlightnotification/enabled
Work in progress (init.d, blinking and other settings)...
Force Fast Charge
This feature allows you to force AC charging for any charger that is detected as USB (eg. PC USB ports, USB Car Chargers) and pull the full current the charger can support, in such a way as to speed up the time required for a complete battery recharge.
By enabling this feature, the USB / ADB data transfers will be disabled (security limitation to protect your data).
How to enable/disable the Force Fast Charge:
1) By using the related setting inside System->Advanced->Force Fast Charge (only on CM 10 Beta 3 and next releases)
2) By downloading and using Trickster MOD or IncrediControl or NsTools
2) By directly editing the file /sys/kernel/fast_charge/force_fast_charge and setting 1 to enable the force charge, 0 to disable it (note that set value will be lost after a reboot/shutdown)
3) By using Terminal Emulator (note that set value will be lost after a reboot/shutdown)
- Open Terminal Emulator
- Run this command to enable the force fast charge feature
Code:
su
echo 1 > /sys/kernel/fast_charge/force_fast_charge
- Then, when you want to restore the normal status, run this command to disable the force fast charge feature
Code:
su
echo 0 > /sys/kernel/fast_charge/force_fast_charge
4) By using a customized init.d script, but I don't recommend it because you have to remember to disable the feature every time you want to connect your device to a pc for data transfering after every reboot
Battery life extender (BLX)
This feature has been developed by Ezekeel and allows to set a customized battery charging limit (100% is the default stock value, if you want, you can set a lower value).
As Ezekeel said, it is commonly accepted that both very low and very high charge states accelerate the degradation of the battery capacity (that is why you should store Li-Ion batteries at around 40% charge).
If you set a charging limit equal to 100, this feature will be disabled.
How to activate this feature and set a customized charging limit:
1) By downloading and using Trickster MOD or NsTools by setting the customized battery life extender charging limit
2) By using a customized init.d script (the custom value will be always restored after a reboot, if you don't format the system partition)

LowMemoryKiller
The LowMemoryKiller driver is used to kill a selected process and free the memory when it is under one of the defined thresholds.
The tuning of the driver could be achieved by means of two parameters exposed by the kernel module via sysfs interface:
- /sys/module/lowmemorykiller/parameters/minfree
This file includes a comma separated array of the threshold numbers for minfree memory size (in page units).
The parameter value set for K^Kernel is "2048,4096,6656,9216,14336,19456".
- /sys/module/lowmemorykiller/parameters/adj
This file includes the comma separated array of oomadj factors, if the corresponding minfree threshold has been reached, one of the process with an oomadj greater than this number will be killed.
The oomadj factor is a property associated to each process, its value is in a range from -17 to +15, the processes with a higher oomadj factor will be the first to be killed when a specific minfree threshold has been reached.
The parameter value set for K^Kernel is "0,20,50,100,250,500".
Frandom - Fast Random Generator
As Eli Billauer (the creator of this module) said, Frandom is a Linux kernel random number generator, which is 10-50 times faster than what you get from Linux built-in /dev/urandom. And it uses very little (/dev/frandom) or none (/dev/erandom) of the kernel's entropy pool, so it is very useful for applications that require a handy source for lots of random data.
How to test if frandom builtin module is correctly working:
- Download the script named frandom_test.sh
- Using your preferred file explorer, copy the file inside the folder /data/local of your device
- Give the rwxr-xr-x permissions to the file (read, write, execution for owner, read and execution for group users, read and execution for others)
- Open Terminal Emulator
- Run this command
Code:
/data/local/frandom_test.sh
You should see a result similar to this one:
If the urandom tests take more than 1 or 2 seconds and are more different than related frandom tests, then the random number generation is not fully optimized for your currently used kernel...
How to disable / re-enable the redirection to frandom module during boot process:
By using Terminal Emulator:
- Run these commands to create the flag file and disable Frandom redirection:
Code:
su
touch /data/frandom_disabled
- Or run these commands to delete the flag file and re-enable Frandom redirection:
Code:
su
rm /data/frandom_disabled
The change will take effect after a reboot.
RAM Console
This feature is useful expecially for development and debugging purposes, when occurs kernel panic / unexpected shutdowns or reboots. Pratically, the kernel messages are also stored inside a little RAM portion and restored during reboot after a kernel panic, inside the file /proc/last_kmsg.
Dynamic FSync
This feature has been developed by Faux123 and allows to dynamically manage the synchronous writes performed on file system (FSync).
It uses asynchronous writes when the screen is on, instead of synchronous writes, to have better performance and a slightly lower battery drain, while when the screen is off the synchronous writes are re-enabled to flush all the outstanding writes and prevent possible data loss.
How to enable/disable the Dynamic FSync (default enabled):
1) By downloading and using Trickster MOD
2) By directly editing the file /sys/kernel/dyn_fsync/Dyn_fsync_active and setting 1 to enable the dynamic fsync, 0 to disable it (note that set value will be lost after a reboot/shutdown)
3) By using Terminal Emulator (note that set value will be lost after a reboot/shutdown)
- Open Terminal Emulator
- Run this command to disable the dynamic fsync feature
Code:
su
echo 0 > /sys/kernel/dyn_fsync/Dyn_fsync_active
- Or run this command to re-enable the dynamic fsync feature
Code:
su
echo 1 > /sys/kernel/dyn_fsync/Dyn_fsync_active
Dynamic dirty page writebacks
This feature has been developed by me and allows to dynamically manage the dirty page writebacks with two different intervals, one when the screen is on and another when the screen is off.
It is based on a commit of Francisco Franco, but instead of using hard coded values and of disabling at all the dirty page writebacks while the screen is on (possibility of data loss), I preferred to use a customizable higher dirty page writebacks interval (15 seconds) than the default one (5 seconds) while the screen is on and a customizable default interval (5 seconds) when the screen is off.
By using a higher interval we have better performance and less battery consumption, with a very low risk of data loss.
How to customize the dynamic dirty page writebacks feature (default enabled):
Three new procfs parameters are exposed inside /proc/sys/vm path:
- dynamic_dirty_writeback is the activation status of this feature, set 1 to enable it, set 0 to disable it and use the standard behaviour
- dirty_writeback_active_centisecs is the interval for the dirty page writebacks when the system is active (screen on), the default value is 1500 centisecs (15 seconds)
- dirty_writeback_suspend_centisecs is the interval for the dirty page writebacks when the system is suspended (screen off), the default value is 500 centisecs (5 seconds)
In my kernel builds, during boot, I set other customized values:
- an interval of 30 seconds while the screen is on
- an interval of 10 seconds when the screen is off
1) By directly editing one of the file written above inside /proc/sys/vm and setting the preferred value (note that set value will be lost after a reboot/shutdown)
2) By using Terminal Emulator (note that set value will be lost after a reboot/shutdown)
- Open Terminal Emulator
- Run this command to disable the dynamic dirty page writebacks feature
Code:
su
echo 0 > /proc/sys/vm/dynamic_dirty_writeback
- Or run this command to re-enable the dynamic dirty page writebacks feature
Code:
su
echo 1 > /proc/sys/vm/dynamic_dirty_writeback
- Run this command to set customize the two intervals (30 seconds while the screen is on, 10 seconds when the screen is off)
Code:
su
echo "3000" > /proc/sys/vm/dirty_writeback_active_centisecs
echo "1000" > /proc/sys/vm/dirty_writeback_suspend_centisecs
Special features and sysfs settings (Part 2):
Timer slack controller and dynamic management of the minimal timer slack value
The timer slack controller is a feature developed by Kirill Shutemov and it allows to set the minimal timer slack value for every process contained within a control group (cgroup).
A timer slack allows the kernel to manage processes wakeup requests at some future time.
Thanks to this feature, the kernel can set a specific timer slack for the involved processes, minimizing the number of wakeups and allowing a lower system's power consumption.
For further info: Timer slack for slacker developers
I also implemented a new feature in addition to the above one that allows the dynamic management of the minimal timer slack value.
So, it's possible to use different minimal timer slack value when the system is active and when has been suspended.
How to customize the dynamic timer slack controller feature:
Three new cgroup parameters are exposed inside each processes hierarchy contained in /dev/cpuctl path:
- timer_slack.min_slack_ns is the timer slack used when the system is active for the current processes hierarchy
- timer_slack.min_slack_suspend_ns is the timer slack used when the system is suspended for the current processes hierarchy
- timer_slack.effective_slack_suspend_ns is the timer slack currently used
At the moment, the values chosen and used by K^Kernel are the following:
- core processes (/dev/cpuctl), 0 ns when the system is active, 50000 ns when the system is suspended
- foreground apps/processes (/dev/cpuctl/apps), 0 ns when the system is active, 250000 ns when the system is suspended
- background non interactive apps/processes (/dev/cpuctl/apps/bg_non_interactive), 100000000 ns when the system is active, 250000000 ns when the system is suspended
1) By directly editing one of the file written above inside /dev/cpuctl and inside each hierarchy subfolder, by setting the preferred value (note that set value will be lost after a reboot/shutdown)
2) By using Terminal Emulator (note that set value will be lost after a reboot/shutdown)
- Open Terminal Emulator
- Run these commands to set the minimal timer slack for generic and core apps/processes
Code:
su
echo 0 > /dev/cpuctl/timer_slack.min_slack_ns
echo 50000 > /dev/cpuctl/timer_slack.min_slack_suspend_ns
- Run these commands to set the minimal timer slack for apps/processes in foreground
Code:
su
echo 0 > /dev/cpuctl/apps/timer_slack.min_slack_ns
echo 100000 > /dev/cpuctl/apps/timer_slack.min_slack_suspend_ns
- Run these commands to set the minimal timer slack for apps/processes in background and non interactive
Code:
su
echo 100000000 > /dev/cpuctl/apps/bg_non_interactive/timer_slack.min_slack_ns
echo 250000000 > /dev/cpuctl/apps/bg_non_interactive/timer_slack.min_slack_suspend_ns
LowMemoryKiller management of not killable processes
This feature allows to define processes and system processes white-lists filled with the preferred process names and to not be killed by lowmemorykiller, unless it is absolutely necessary.
This feature exposes four new lowmemorykiller parameters:
- donotkill_proc, is the flag to enable / disable this feature for the processes chosen by the user
- donotkill_sysproc, is the flag to enable / disable this feature for the system processes chosen by the user
- donotkill_proc_names, is the list of process names (comma separated) chosen by the user to be preserved from killing
- donotkill_sysproc_names, is the list of user system process names (comma separated) chosen by the user to be preserved from killing
When the lowmemorykiller needs to free ram, it will first kill the processes not included inside the two process name lists chosen by the user.
If there are no more standard killable processes, then it will be necessary to kill one of the processes included inside one of the two white-lists, to prevent system hangs, slowdowns, etc.
How to customize the white lists of processes to preserve from killing:
On K^Kernel the feature is enabled by default and the provided processes white lists are the following:
- donotkill_proc_names = "com.cyanogenmod.trebuchet,com.anddoes.launcher,com.teslacoilsw.launcher,org.adwfreak.launcher,gtp.nextlauncher,android.inputmethod.latin,com.touchtype.swiftkey"
this means that Trebuchet Launcher, Apex Launcher, Nova Launcher, ADW Launcher, Next Launcher, stock keyboard and SwiftKey keyboard will be preserved from killing
- donotkill_sysproc_names = "android.process.acore,com.android.phone,com.bel.android.dspmanager"
this means that the system process, the phone process and DSP Manager will be preserved from killing
1) By using a customized init.d script (the custom value will be always restored after a reboot, if you don't format the system partition)
- Download the script named 80dnkp
- If the file has been saved with .txt extension (stock browser), rename it by removing the .txt extension
- Edit the file by setting your preferred status and processes list
- Copy the new file inside /etc/init.d
- Give the rwxr-xr-x permissions to the file (read, write, execution for owner, read and execution for group users, read and execution for others)
- Reboot
2) By directly editing the files inside /sys/module/lowmemorykiller/parameters (note that set values will be lost after a reboot/shutdown)
3) By using Terminal Emulator (note that set values will be lost after a reboot/shutdown)
- Open Terminal Emulator
- Run these commands if you want to enable the feature
Code:
# To enable this feature for the processes chosen by the user
echo 1 > /sys/module/lowmemorykiller/parameters/donotkill_proc
# To enable this feature for the system processes chosen by the user
echo 1 > /sys/module/lowmemorykiller/parameters/donotkill_sysproc
- Run these commands if you want to disable the feature
Code:
# To disable this feature for the processes chosen by the user
echo 0 > /sys/module/lowmemorykiller/parameters/donotkill_proc
# To disable this feature for the system processes chosen by the user
echo 0 > /sys/module/lowmemorykiller/parameters/donotkill_sysproc
- Run this command if you want to add, for example, Trebuchet Launcher (CM default launcher) and the default keyboard to the processes white list
Code:
echo "com.cyanogenmod.trebuchet,android.inputmethod.latin" > /sys/module/lowmemorykiller/parameters/donotkill_proc_names
- Run this command if you want to add, for example, the system process, the phone process and DSP Manager to the system processes white list
Code:
echo "android.process.acore,com.android.phone,com.bel.android.dspmanager" > /sys/module/lowmemorykiller/parameters/donotkill_sysproc_names
ZRAM module
As explained on Wikipedia, this feature, provided in this kernel as a standalone loadable module, increases performance by avoiding paging on disk and instead uses a compressed block device in RAM in which paging takes place until it is necessary to use the swap space on the hard disk drive.
In few words, the memory pages no more used and so to be swapped are sent to zRam device blocks, compressed and stored in memory instead of disk allowing better performance and also lower memory usage, on the other hand, a little higher amount of cpu is needed to perform compression and decompression of memory pages.
Since we have a device with a low amount of free memory, this feature could be useful to have more free ram.
How to change the size of zRam or to disable it (thanks to @ktulu84 for sharing these scripts):
To change the size of zRam (the custom value will be always restored after a reboot, if you don't format the system partition):
- Download the script named 60zram
- If the file has been saved with .txt extension (stock browser), rename it by removing the .txt extension
- Edit the file by setting your preferred zRam size (change SIZE value, default is 100 MB)
- Copy the new file inside /etc/init.d
- Give the rwxr-xr-x permissions to the file (read, write, execution for owner, read and execution for group users, read and execution for others)
- Reboot
If you want to use default zRam size, simply remove the file placed inside /etc/init.d and reboot.
To disable zRam (the custom value will be always restored after a reboot, if you don't format the system partition):
- Download the script named 60disable_zram
- If the file has been saved with .txt extension (stock browser), rename it by removing the .txt extension
- Copy the new file inside /etc/init.d
- Give the rwxr-xr-x permissions to the file (read, write, execution for owner, read and execution for group users, read and execution for others)
- Reboot
If you want to re-enable zRam, simply remove the file placed inside /etc/init.d and reboot.
FAQ - Frequently asked questions:
Q: What are the differences between EXUV and UV kernel versions?
A: The EXUV kernel versions have extremely undervolted settings for the cpu frequencies, they allows to have a very low battery drain, instead the UV kernel versions have undervolted settings a bit higher than EXUV versions, but always lower than stock kernel settings.
The EXUV kernel versions could give some problems (freezes, shutdowns, huge lags) on some devices because the cpu doesn't support too low voltage settings.
For a lower battery consumption, I suggest you to try EXUV versions first and to switch to UV versions only if you encounter one of the above mentioned problems.
Q: For kernel v4.0 and before, what are the differences between 398MB, 406MB and 416MB versions?
A: 398MB, 406MB and 416MB kernel versions have different free ram available for user space, with a higher free ram your device will work better with heavy apps, many concurrently used apps, heavy games, etc.
- 398MB versions have the same amount of free ram than stock kernels, they are more stable, everything is fully working, but you could have some slowdowns with apps that require a high amount of free memory.
- 406MB versions have additional 8 MB of free ram than stock kernels (that memory has been taken from SurfaceFlinger reservation), they are suitable for the users that use the device primarly for calls, messages, simple apps and simple games. The camera, video recording (both 480p and 720p modes) and video playback are fully working.
- 416MB versions have additional 18 MB of free ram than stock kernels (that memory has been taken from SurfaceFlinger reservation), they are suitable for the users that use the device also with heavy apps, various concurrently used apps and games. The camera, video recording (both 480p and 720p modes) and video playback are fully working.
Q: Why should I deactivate KSM (Kernel Samepage Merge)?
A: KSM (Kernel Samepage Merge), let us save a bit of RAM space used by kernel (max 10MB during my analysis) by merging duplicated memory pages used by different processes, but it has also some performance impacts, since it uses CPU time to perform those memory scanning and merging operations.
So, in few words, it could free up a bit of RAM, but sometimes keeps the CPU busy to complete its work.
After introducing the dynamic allocation of MM ION and PMEM ADSP heaps, KSM could cause issues while trying to use camera or camcorder and playing HW/HW+ videos.
This is due to the impossibility to allocate one or more memory pages that have been merged by KSM inside the memory area reserved for dynamic allocations for MM ION or PMEM ADSP heaps through CMA (Contiguous Memory Allocator).
I'm looking for a solution for this "incompatibility", but at the moment the tried changes didn't work.
So, as a workaround, don't activate KSM until we find a fully working solution, since the RAM freed by dynamic allocation is surely higher than KSM freed RAM without any performance impact during normal usage.
The option can be deactivated inside Settings -> Performance -> Memory management -> Kernel samepage merging.
Q: How can I get the Performance and Developer Options entries inside Settings menu?
A: Go inside Settings -> About Phone -> Scroll down and tap 7 times on Build number (it's an Easter Egg).
Q: How can I get the log after an unexpected shutdown / reboot?
A: After an unexpected shutdown / reboot of the device, if the problem may be kernel related, you should have the /proc/last_kmsg, if so, send me that log and I'll check it to find the possible cause of the problem.
Q: How can I get the logs when I encounter strange system issues while it's running?
A: Check first if the problems could be related to an app you're using and if you changed something in the last days before facing those issues.
If the problem started after installing the kernel, then let me have you logcat and dmesg:
- Open Terminal Emulator and execute these commands:
Code:
su
dmesg > /sdcard/dmesg.txt
locat -v time -d > /sdcard/logcat.txt
- Open you preferred file manager and go inside the internal sd card partition /sdcard
- Send me the dmesg.txt and logcat.txt files, if you want zip them first
Q: How can I mount a shared Windows folder with CIFS module?
1) By using Terminal Emulator
Code:
mount -o unc=\\\\[COLOR="DarkGreen"][I]ip[/I][/COLOR]\\[COLOR="Blue"][I]share[/I][/COLOR],noserverino,username=[I][COLOR="DarkOrange"]user[/COLOR][/I],password=[I][COLOR="Lime"]password[/COLOR][/I] -t cifs //[COLOR="DarkGreen"]ip[/COLOR]/[COLOR="Blue"]share[/COLOR] [I][COLOR="DarkSlateGray"]/mnt/cifs[/COLOR][/I]
2) Downloading and using CifsManager and configuring the new share as follow:
- Share Path = ip/share
- Mount Point = /mnt/cifs/share
- Username = username
- Password = password
- Options = unc=\\\\ip\\share,noserverino
Where:
ip is the ip address of your pc where the folder is shared
share is the shared folder name
user is the user name that can access the shared folder
password is the user password
/mnt/cifs is the mount point (must be created if you'd like to use the command approach with Terminal Emulator)

Hi Christopher!
I like your products but I have a problem. When I listen to music on stock kernel, I almost don't hear the noise. When I use your kernel, the noise on the headphones is several times louder. I listen music on the SoundMagic e10 headphones and I don't hear the noise on other phones (for example Nokia E52).
Could you do anything with that?
I would be thankful!

#you can set the max cores
maxcoreslimit by default use the 4 cores
maxcoreslimit_sleep by default use 1 core
min_cpus_online by default 1
Code:
echo "numofthemaxcore" /sys/kernel/klozz_hotplug/maxcoreslimit
ejem: echo "2" /sys/kernel/klozz_hotplug/maxcoreslimit
echo " 2" /sys/kernel/klozz_hotplug/maxcoreslimit_sleep
echo "2" /sys/kernel/klozz_hotplug/min_cpus_online
New governor: detailed info in spoiler
-- Adaptive
This driver adds a dynamic cpufreq policy governor designed for latency-sensitive workloads and also for demanding
performance.
This governor attempts to reduce the latency of clock increases so that the system is more responsive to
interactive workloads in loweset steady-state but to to reduce power consumption in middle operation level level up
will be done in step by step to prohibit system from going to max operation level.
-- AbyssPlug
'abyssplug' - this driver mimics the frequency scaling behavior in 'ondemand', but with several key differences. First is
that frequency transitions use the CPUFreq table directly, instead of incrementing in a percentage of the maximum
available frequency. Second 'abyssplug' will offline auxillary CPUs when the system is idle, and online those CPUs once the
system becomes busy again. This last feature is needed for architectures which transition to low power states when only
the "master" CPU is online, or for thermally constrained devices.
-- Alessa (My own gobernor Bugged for now :/)
#Dedicated to Stephanny Cooper :#
Based on ondemand less aggressive and more stable. A good compromise between performance and battery.
and ussable with my own hotplug

Note: what is VFP?
Floating-point (VFP)
VFP (Vector Floating Point) technology is an FPU coprocessor extension to the ARM architecture. It provides low-cost single-precision and double-precision floating-point computation fully compliant with the ANSI/IEEE Std 754-1985 Standard for Binary Floating-Point Arithmetic. VFP provides floating-point computation suitable for a wide spectrum of applications such as PDAs, smartphones, voice compression and decompression, three-dimensional graphics and digital audio, printers, set-top boxes, and automotive applications. The VFP architecture was intended to support execution of short "vector mode" instructions but these operated on each vector element sequentially and thus did not offer the performance of true single instruction, multiple data (SIMD) vector parallelism. This vector mode was therefore removed shortly after its introduction, to be replaced with the much more powerful NEON Advanced SIMD unit.
Some devices such as the ARM Cortex-A8 have a cut-down VFPLite module instead of a full VFP module, and require roughly ten times more clock cycles per float operation. Other floating-point and/or SIMD coprocessors found in ARM-based processors include FPA, FPE, iwMMXt. They provide some of the same functionality as VFP but are not opcode-compatible with it.
VFPv1
Obsolete
VFPv2
An optional extension to the ARM instruction set in the ARMv5TE, ARMv5TEJ and ARMv6 architectures. VFPv2 has 16 64-bit FPU registers.
VFPv3 or VFPv3-D32
Implemented on the Cortex-A8 and A9 ARMv7 processors. It is backwards compatible with VFPv2, except that it cannot trap floating-point exceptions. VFPv3 has 32 64-bit FPU registers as standard, adds VCVT instructions to convert between scalar, float and double, adds immediate mode to VMOV such that constants can be loaded into FPU registers.
VFPv3-D16
As above, but with only 16 64-bit FPU registers. Implemented on Cortex-R4 and R5 processors.
VFPv3-F16
Uncommon; it supports IEEE754-2008 half-precision (16-bit) floating point.
VFPv4 or VFPv4-D32
Implemented on the Cortex-A12 and A15 ARMv7 processors. VFPv4 has 32 64-bit FPU registers as standard, adds both half-precision extensions and fused multiply-accumulate instructions to the features of VFPv3.
VFPv4-D16
As above, but it has only 16 64-bit FPU registers. Implemented on Cortex-A5 and A7 processors.
What is NEON?
Advanced SIMD (NEON)
The Advanced SIMD extension (aka NEON or "MPE" Media Processing Engine) is a combined 64- and 128-bit SIMD instruction set that provides standardized acceleration for media and signal processing applications. NEON is included in all Cortex-A8 devices but is optional in Cortex-A9 devices. NEON can execute MP3 audio decoding on CPUs running at 10 MHz and can run the GSM adaptive multi-rate (AMR) speech codec at no more than 13 MHz. It features a comprehensive instruction set, separate register files and independent execution hardware. NEON supports 8-, 16-, 32- and 64-bit integer and single-precision (32-bit) floating-point data and SIMD operations for handling audio and video processing as well as graphics and gaming processing. In NEON, the SIMD supports up to 16 operations at the same time. The NEON hardware shares the same floating-point registers as used in VFP. Devices such as the ARM Cortex-A8 and Cortex-A9 support 128-bit vectors but will execute with 64 bits at a time, whereas newer Cortex-A15 devices can execute 128 bits at a time.

Explanation of XPerience Gobernor:
XPerience gob - based on SmartassV2 Optimized parameters for proper scaling on frequency,
gradually scale frequencies up to the highest depending on the needs of processing.
Getting a little boost when necessary according to MPDecision
Such as adjustable parameters were added:
Code:
awake_ideal_freq; 780mhz by default
sleep_ideal_freq; */ 600mhz by default and are good./*
ramp_up_step; */356mhz so scaleable by 356mhz up to the maximum frequency*/
ramp_down_step; */the same like up but are for max to min*/
max_cpu_load; */ CPU freq will be increased if measured load > max_cpu_load*/
min_cpu_load; */ CPU freq will be decreased if measured load < min_cpu_load;*/
sleep_wakeup_freq; */The frequency to set when waking up from sleep. set to máx posible by procesor*/

Hello, friend.
Inspired by @wrongway213's original custom kernel for Pixel 4/XL, I decided to make my own project once I grab my hand on a Google device myself. The naming is a tribute to both his ideas and Mr. Robot. fsociety tribute's goal is to give the device a set of useful features while ensuring its stability for a daily life usage. Those features and changes are pulled from different places like blu.spark, Sultan kernel, Kirisakura and many more.
Features
General features
Built with Google Clang version 14.0.2 + LLD linker
Full -O3 build with chipset's flags included (thanks to @eng.stk and @Sultanxda)
AnyKernel3 powered installation to stay OTA and flashers (EXKM, FKM...) friendly
ARM64 architecture optimization and performance patches
Merged security and code fixes from Google and Qualcomm - CAF
Filesystem (ext4/f2fs) optimizations
Scheduler code improvements for better CPU tasks assigning
Disabled several debugging cruft
WireGuard support
Memory related features
Merge zRAM and zRAM's compression algorithm code updates
Increase zRAM's disksize to 4GB (from the stock 2GB). Apps can be easily memory intensive nowadays...
Swap 1 page at a time instead of the default's 8, so that it may help in case "the device is under extreme memory pressure"
(source: https://source.android.com/devices/tech/perf/low-ram)
Reduce memory and CPU time usage by avoiding dynamic memory allocations in different kernel components (thanks to @arter97 and @Sultanxda)
Network related features
Set BBR as the default TCP network congestion control and switch to fq_codel queue discipline
(this combination improves network speed and reliability - thanks to @kdrag0n)
Enable support for TTL spoofing
Update Wireguard to its latest release
Power-saving related features
The processor uses freq-energy-model with calculated capacities for power efficiency
Some of the main kernel parts (such as the audio drivers and the WLAN driver's delayed work/tasks) now use power-efficient workqueues (thanks to @Freak07)
Display "power-saving tweaks" merged-in (from Proton kernel - Pixel 4a 5G/Pixel 5)
Reduce the GPU idle timeout set to 58 ms and implement GPU power-saving changes from Sultan kernel
battery: Tweak QG SOC to be more linear/monotonic (from Proton kernel)
That fixes the stock kernel's unlinear battery level curve, especially between 100% and 90%. The device will need a few charge-discharge cycles to take it into consideration
Performance related features
Implement LRNG for better performance
Disable the GPU memory usage tracing (which was enabled for debugging purposes)
Return before thermal trip evaluates (it is a workaround for the lag occurring when the device is low on battery and automatically switches to battery saving mode)
Other under the hood changes
Extra features
KCAL Color Control with KLAPSE v5.0 support (thanks to @savoca, @tbalden, @flar2 and @eng.stk)
Backlight min. brightness and HBM option (thanks to @flar2)
Boeffla Wakelock Blocker (to use with caution, and only if it is necessary)

Based on bluespark kernel? imagine it doesn't have support for usb dacs right?

It has got major blu.spark's elements in it, yes. It also uses @eng.stk's excellent soucedrops from Google. The latest update from blu.spark and fsociety tribute has got a change related to your issue. You should try and let us know if the problem got fixed!

I can give it a try tomm, just flashed the new release bluspark put out yesterday and my DAC unit seems to work with the changes he made.Just testing it for stability for now.Good to see more developers making kernels for this device.

Hello friend,
I will try to compile a version containing those specific changes when I have some free time and send you the zip file. However, they will not be incorporated to the main version. If you have a Linux powered computer/laptop, I will be glad to show you how I did it and how you could compile it yourself, so that you may add them for each new version.
Will I run into any issues if I try and flash this when I'm running the newest lineage build?
Hello everyone, new promising update!
Changelog
fsociety tribute alpha#1.02
A bunch of optimization commits used in Kirisakura included. Huge respect to @Freak07.
These changes mainly concern the GPU and the CPU architecture.
In addition to this, normal grace periods are now preferred to reduce power usage (Thanks a lot to @kdrag0n for his approach).
Finally, boeffla wakelock blocker doesn't block any wakelock by default for now, but you can add your own ones to the blocklist.

It should work fine! The kernel is still is its testing phase, so I would like to know if it does run with LineageOS. However, my priority is its usage on stock ROM.

Thanks a bunch man I have tried and failed several times to get it working.
Great job!
As promised I tried it,so far it works ok.My USB DAC works fine and everything inc mqa,dsd play no issues.Noticed with 1.01 it was running bit warmer my device with normal use like surfing when it usually never did,however 1.02 seems fine? Possible it is nothing.
If I may ask,what is the changes/differences between this and bluespark? Looking at the description for both kernels they look about the same.OC is not enabled by default right?

I am glad it is working as it should be.
I would say that fsociety tribute is on its way to become more and more distinct.
It is true that it is based on @eng.stk's excellent initial building setup and his Google sourcedrops, as I was not knowledgeable enough to do it by myself (they have my gratitude). Some features to me were appealing, like its incorporation of KLAPSE and KCAL or its choice for Zen v2 as the default I/O scheduler. However, according to my own preferences, I did not pick up the USB Fast Charge and the FS fsync's tweaking support features for example or compile the kernel with the -O2 optimization flag.
The next build will use BBR v2 instead of Westwood as the default TCP congestion control.
I am still at the beginning of my journey to explore and learn what would be appealing to my vision for fsociety tribute, hence the alpha stage it is under right now. Feel free to choose whatever suits you!
Hello everyone, another update! It is temporarily uploaded on GIthub until Sourceforge stops being buggy.
Changelog
fsociety tribute alpha#1.03
BBR v2 set as the default TCP network congestion control instead of Westwood (thanks to @Freak07).
Thanks to @LazerL0rd for having these changes imported :
- Imported upstream Bluetooth fixes.
- fs: ext4: fsync: optimize double-fsync() a bunch.
- Initialize ata before graphics.
- Re-enabled BPF JIT compiler to improve gaming and overall system performance
(thanks to @Sultanxda).
- arm64: lib: memory utilities optimization.
