marc1706's 2.6.35.14 ICS & JB Kernel
This kernel is based on the HTC Desire 2.6.35.10 kernel source code ported by warrenb213 and me with help from Markinus' CyanogenMod kernel source.
This kernel is only for ICS/JB ROMs and shouldn't be used on any older ROMs. Only use the ICS kernel on ICS ROMs and the JB Kernel on JB ROMs!
Features:
Default CPU governor: ondemand
Default CPU speed: 245 MHz - 998 MHz
Available CPU speeds: 96 MHz - 1536 MHz (if speeds above 1190 MHz are not stable for you, stick to lower frequencies)
Available CPU governors: interactive, conservative, userspace, powersave, ondemand, performance, smartassV2, Lagfree, Lazy, SavagedZen, scary, smartass, smoothass, superbad, virtuous, interactiveX, ondemandX
Default IO Scheduler: BFQ
Available I/O schedulers: no-op, deadline, CFQ, BFQ, simple IO, VR
G-Sensor freeze fix (Credits: mdebeljuh and jdivic)
Wakeup lag fix for AUO panels (Credits: mdebeljuh and jdivic)
cLK support
Extended battery support (still needs some testing, I don't have an EB)
BFS CPU scheduler (disabled in JB Kernel 0.1.2+)
ALSA sound drivers
Simple IO Scheduler
HTC Auto-White Balance
Two-way call recording (Credit to avs333, snq-, tytung)
add proc file interface /proc/mic_level and fix mic gain (Credits to mdebeljuh and jdivic, tytung)
zRam (Credits: me, faux123): Activation script can be found here
xt_qtaguid: Monitor network traffic
ICS HWA (credits to Rick_1995, SecureCRT, Xylograph, tytung)
KGSL v3.8 (credits to Rick_1995, small parts by me)
Real MAC address (credits to Franck78, Rick_1995, me)
HTC HD2 off-mode alarm (credits to kokotas, Rick_1995; cleaner implementation by me)
Working:
Data
Wifi
Bluetooth

FAQs:
My phone sometimes lags when I unlook it. After 1-2 seconds the lag is gone. Is there a way to fix this?
Yes, just set the minimum cpu speed to 245 MHz. The snapdragon cpu is not able to scale from 128 MHz to any given frequency. From 128 MHz it can only scale to 245 MHz and then it'll scale to higher frequencies.
Can we have ZSL (= zero shutter lag) on the HD2?
No. ZSL was created for newer smartphones that have camera sensors that support ZSL.
My phone suddenly can't connect to my Wifi router after updating to this kernel.
Your phone will have a new wifi mac with this kernel. You will need to allow this new mac address if you have mac address filtering enabled on your router.
Have fun with the ICS kernel.

Thanks a million for all that you do with our Hd2. Cheers

@marc1706
So I installed the 0.1.1 kernel it was very very smooth. So I rebooted the phone but when it restarted my apps were gone. My free space is now at 0 see attached 1st. pic. Running Smokin's MIUI-US-2.5.11-HWA. Is this a kernel problem? Cheers
Edit: My setup also included Setcpu with lagfree governor no profiles 245 min 1036 max I have also installed a2sd. I booted to recovery flashed tytungs-HWA-r2.3-uniMAC and my apps kinda returned. They are all there but not in same order as I had them set to display. Any ideas ?
Edit2:
After being satisfied that my data was ok. I re flashed your kernel and again after reboot same problem. So I'm thinking there is an issue with a2sd and your kernel. Cheers

As someone said Marc for president
I think that XDA have to enlarge number of thanks per day since I have gave only 8 thanks today and Marc, Rick, Securecrt, Rapmv78, SBbryan, Xylo, Tytung and others deserve million thanks
Brilliant kernel overall...everything is working and feels quite snappy, maybe faster than .32 kernel
One issue - I,m using amarullz a2sd script and kernel causes low sound bug ( I reflashed tytung .32 kernel and the sound bug was gone). Fix permissions does not solve the issue.
Cheers

Really? How am I supposed to put Sense into a kernel?
If you are asking if this is an ICS Sense kernel:
I think HTC stopped messing kernels up for sense. If we need something special for sense 4.0 I think I'll soon found out.
If you have issues with A2SD reboot into recovery and make sure to fix permissions and wipe the dalvik cache.
Using the kernel on Xylo's AOKP milestone 5 HWA.
Very good so far, except an FC on Settings ... Wireless & Network ... More
(i.e. APN settings, etc.)
Not a problem as my data/APNs are fine.
Email is FCing too - just re-creating my accounts now to see if that fixes it.
Cheers
EDIT: think I have tytung's 2.3-uM initrd as that was my previous kernel.
doesn't boot ics1.1 on tostidroid 1.1 magldr

You can try,go in recovery clear cache & wipe dalvik cache.
Kernel is amazing,running on IceCreamTosti v1.0 PE B35 smoot & fast,no fc's at all,data,wifi,calls ok,battery 2-6mA on standby.....so far so good...

Cheers Marc. Did a couple of dalvik wipes and re-created the accounts. Seems to have settled down now. APN settings page no longer FC's now too.
Will continue testing and report back.
On ICS kernel in CM9 nightly (13th May) with app and app-private symlinked to SD EXT. Just flashed the kernel- no issues, no FC, all apps area there and work fine, email accounts work. I didn't clear dalvik cache or fix permissions...

Hi Marc,
Just to confirm a little more testing.
Bluetooth is working perfectly in this kernel. In fact, it's the best I've tried yet for ICS. I have a Nokia BH-505 BT headset, which on tytung's and securecrt's kernels, have always "fed-back" the microphone audio into the headphones, so I can hear myself speaking and get lots of background noise in calls. Yours does not seem to do that. AVRCP stuff is working fine too, so, all in all, very very pleased with your kernel.
Thanks very much for your hard work. Fantastic.

sorry, but I meant sd/magldr boot I understand, that the kernel was not designed for the sd builds.
just for the dev info. that would be great it would be possible to use marc's kernel with sd ics builds.
at least, sense kernel we can use
I'm not sure how the whole SD boot is handled but could try going to services -> Dump dmesg to sd in Magldr after the reboot?

Special Features
MSM_LIMITER
This function will limit the cpu in certain condition such as frequency during suspend, resume and min frequency. This features enabled in default and the frequency already been set for suspend freq to 900Mhz (screen off), min freq 245Mhz, resume freq 1.4Ghz. This feature may can reduce power consumption as it limit our cpu frequency after the screen off. If this features enabled, OC frequency will be override automatically after the screen off = 900Mhz and resume back to 1.4Ghz. Thus, you need to disable it if you like to make OC frequency stays,
so here the step to disable it: -
1. By using Terminal Emulator (note that set value will be lost after a reboot/shutdown)
- Open Terminal Emulator
- Run this command to disable msm_limiter feature
Code:
su
echo "0" > /sys/kernel/msm_limiter/limiter_enabled
echo "0" for disable or echo "1" for enable it back
2. Download the msm_limiter_switch.sh.pdf
- after download the script please rename the file by removing .pdf and the name of the file should be like this msm_limiter_switch.sh
- by using Script Manager application open the msm_limiter_switch as script and tick the the "boot"
- by doing this, the msm_limiter will stick disable after the boot
in advance step, you can adjust the frequency of suspend, resume and min frequency to suit your taste here the command
1. For resume frequency
Code:
su
echo "<put ur own frequency here>" > /sys/kernel/msm_limiter/resume_max_freq
example:-
Code:
su
echo "1824000" > /sys/kernel/msm_limiter/resume_max_freq
this will make your CPU freq up to 1.8Ghz when screen on.. it just an example.
2. For suspend frequency
Code:
su
echo "<put ur own frequency here>" > /sys/kernel/msm_limiter/suspend_max_freq
Table of our devices frequency
Code:
122880
245760
368640
768000
806400
902400
1017600
1024000
1113600
1209600
1305600
1401600
1516800

1824000
Android Logger ON/OFF mode
Android logger can be turn off/on when you need or did not need it in this kernel, this function was introduced to reduce A BIT cpu usage or ram consumption that be used by the logger. The android logger was set OFF in default for this kernel :-
Here the step to change the logger mode:-
-the option of the mode-
/*
* 0 - Enabled
* 1 - Auto Suspend
* 2 - Disabled
*/
1. By using Terminal Emulator (note that set value will be lost after a reboot/shutdown)
- Open Terminal Emulator
- Run this command to disable the logger
Code:
su
echo "you choice of logger mode" > /sys/module/logger/parameters/log_mode
Example
Code:
su
echo "2" > /sys/module/logger/parameters/log_mode
Gentle fair sleepers
Disable gentel fair sleepers will give you better UI performance.. disabling it will make your phone consume more power due to several reason (i forgot the source of this statement), btw you can change it to suit your taste
-the option of the mode-
/*
* 0 - Disabled
* 1 - Enabled
*/
Code:
su
echo "you choice" >/sys/kernel/sched/gentle_fair_sleepers
Example
Code:
su
echo "1" >/sys/kernel/sched/gentle_fair_sleepers

do you have a plan for make this kernel swapped sir?

You can swap memories with lagactorial ketnel if you want. As far as i know Hurtsky is not supporting this feature.
I keep reading it every where about swapping memories people are going crazy...but what are the benefits of this. I think it cant make any changes on performance. Maybe im wrong...

JUST ANOTHER KERNEL for Cyanogenmod 11.0 (unofficial)
Hi friends,
i had some fun the last weeks succesfully compiling a kernel on my own.
But because of my lack of knowledge how to improve the kernel further and the things are getting more and more complicated, i decided to stop my efforts for now.
Nevertheless i like to share my work with you and you are free to test the kernel and comment, if it is working fine for you as well. All kernel developers are free to have a look into my github and watch for maybe something useful to pick up for their work too:
GitHub
Credits & thanks goes to:
arco68, christopher83, AriesVE-DevCon-TEAM, hurtsky, madridii, lafactorial, arsradu, leroviten, sir mordred, all other authors you can see in the commits in my kernel branch, all friendly guys in the community who continuously delivering a lot of useful tools and tutorials for kernel development, and last but not least all participating users who keep this forum for the GALAXY Wonder alive!
-------
Main and common features, seen in the other kernels already:
- compiled with Linaro GCC 4.8.4-2014.11 Toolchains optimized for Cortex-A8 - by Christopher83
- O3 Optimization & NEON VFP compilation flag
- Governors: interactive default, conservative, lulzactive, interactiveX, ondemand, ondemandX, powersave, smartassV2, performance
- I/O schedulers: cfq default, noop, vr, sio, row, bfq, fiops, deadline
- Lowered display panel voltage
- Lowered wifi voltage
- Lowered vibetonz voltage
- Increased audio loudness
- Battery Life eXtender support
- Fast Charge support
- CPU voltage control VDD sys interface / Overclockable up to 1.8 GHz
- Increased cpu freq. on boot
- Fast Random generator (frandom)
- Dynamic management of the minimal timer slack value
- Dynamic management of dirty page writebacks
- Dynamic FSync v1.2
- msm: memutils: memcpy, memove optimization
- Disabled Gentle Fair Sleepers for better UI performance
- Optimized AES and SHA1 routines for ARM cpu architecture
- exFAT support
- LowMemoryKiller management of not killable processes
Additionally i experimented with some new stuff, hopefully trying to improve the memory management:
- MM patch bomb, regarding vmscan, compaction, page_writeback, oom_kill, slub,...
- new small and naive hashtable implementation
- red-black tree implementation & changed lowmemorykiller behaviour
- some miscellaneous updates
Highlight feature:
- fast lz4 compressed zram
Attention:
Zram will be set to a high size via init script provided by @ktulu84. Thank you.
Some do not kill processes for the 'LowMemoryKiller management of not killable processes' will be set via init script too. Credits to Christopher83 again.
To disable the zram script and use the default rom value again, just remove the file 'zram_high' placed in the folder '/system/etc/init.d/'.
Or just install latest Performance Control 2.2.4 by h0rn3t for easy control of the values. Recommended.
Disabling zram via performance control will delete the max_comp_streams setting. Before restart i recommend to open terminal emulator and enter the following commands:
su
echo 8 > /sys/block/zram0/max_comp_streams
Explanation for these changes:
In my experience the new lz4 compressed zram does a good job for very high memory demanding system configurations.
The i/o speed will possibly decrease, but in my understanding you will benefit due to the fact, that most processes can be swapped now faster and are not forced to be closed & have to restart later again.

I guess not. I have to ask madridii if it is possible.
thanks tycoo for the new kernel compiled with latest linaro.
This kernel has trim support?

which kernel use for mokee rom ?

I dont think so, stability has my priority. I suggest to increase the zram value & swappiness, should be faster than before.

I guess @theloneseeker has to modify my kernel or to explain me what to do.
@dodora3d,this kernel does not support mokee rom yet because mokee R5 base is CM11 build date 21/05/14.I believe this kernel is compatible only with CM11 dated 28/05/14.
@tycoo,the kernel needs only a small addition because of the additional framework files,but i will do it in my next release.I just dont need you to make kernels for every Rom seperately.
Continue the good work buddy:good::fingers-crossed:
Hey mates,
no posts = no complains i guess.
However, i am interested in some feedbacks if you don't mind.
For example, how is the performance in gaming, did you made some good experiences with the updated & faster (i believe) running zram,..?
cheers

I've had random locks and hot reboots with anything above 1.6GHz before on other kernels, and 1.8 works with this one without errors. Occassional graphical flicker or boot logo appearance after PIN entry but nothing majorly setting back. Could be because of other mods used by me.

You're right, i remember this too.
I am actually testing a new kernel and going to upload it soon. Lets see if the graphical flickers will disappear.
op updated with JAKStage5.3
op updated with
JAKStage6_UV_HM407MB - 3.4.94 - for ROMS since and based on Cyanogenmod 11.0 (20140616-UNOFFICIAL)
New build based on new KK2.7 CAF-Branch provided for samsung msm7x30 devices by Christopher83 & arco68!
Credits & thanks again to @Christopher83 @arco68 @hurtsky @sir mordred for their fantastic work and kernel sources, my build is up to 95% or more based on! I just reorganized most things for my needs and merged them together again.
Attention:
With installing the kernel, vm swappiness will be set to 85.
Zram will be set to a default size of 230MB via init script provided by @ktulu84 Thank you.
Some do not kill processes for the 'LowMemoryKiller management of not killable processes' will be set via init script too. Credits to Christopher83 again.
To disable the zram script and use the default rom value again, just remove the file 'zram_high' placed in the folder '/system/etc/init.d/'.
Explanation for these changes:
In my experience the new lz4 compressed zram does a good job for very high memory demanding system configurations.
The i/o speed will possibly decrease, but in my understanding we will benefit due to the fact, that most processes can be swapped now faster and are not forced to be closed & have to restart later again. So at the end the overall performance will be better, hopefully.
What else:
undervolted highmem version
disabled KSM on kernel side
enabled QuickWakeup Driver again
some minor zram & lmk updates and changes

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: v3.0
Stable Release Date: 2015-04-05
Created 2014-06-17
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
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 I8150 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
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 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: What are the differences between 396MB, 406MB and 416MB versions?
A: 396MB, 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.
- 396MB versions 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 10 MB of free ram, 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 20 MB of free ram, 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...

Well for now, I'll stick around with skernel since it is more optimized and stabilized with the ROM I am using now.
Moreover, the one with BLN and tap2unlock support is far more convincing. And I'll definitely stick to the one whichever adds it.

Is it possible for you to add this patch bro? that'd be awesome.
Double tap to wake would be interesting as well @aidasaidas75 is it possible? And, can u update Carbon ROM? Its awesome but outdated..
