CHANGELOG
CM 10.1 - v2.6 (14 OCT)
Ondemand and dynamic hotplug patches by stratosk
More RAM(790-791MB) (Experimental)
Remove some governors and IO schedulers (lean kernel)
Disable some debugging functions (lean kernel)
Linux 3.0.100
JB - v2.5 (27 JUL)
remove mpdecision
backport stratosk 's nexus 4 ondemand and dynamic hotplug
ondemand: touch_load increased to 1134Mhz for 1.3sec duration
ondemand: touch_load is applied only to CPUs the load is above 35%. So, CPUs with low load (and most probably unused) are not boosted.
These ondemand governor parameters are tunable in TricksterMod
Few patches to improve video overlay
Linux 3.0.87
JB - v2.4 (26 JUN)
"simple" GPU governor by faux123 + patch by franco
"simple" GPU governor set by default ( Currently only fauxclock shows/supports the correct option of simple governor )
Backport ondemand from CAF 3.4 kernel
Set SIO IO Scheduler by default (I did some benchmark tests and found out this is the fastest)
Update latest CM10.1 kernel source
Linux 3.0.83

Logger driver update by stratosk
some misc backport,fixes
Linux 3.0.75
JB - v1.8 (15 APR)
BSODs from v1.7,v1.71 should be fixed
- Sorry for previous instable release and late coming v1.8
IO Scheduler: Add ROW
- As requested
CPU Governor: Set Ondemand(tweaked 2phase) as default
- By my observation, onedemand,badass seem to be more battery friendly due to shorter time in max freq.
Remove UKSM
- Cons>Pros
- if needed, Check stock KSM in Option - > Performance - > Memory Management
Revert CM screen off fix
- It seems disturbing wifi fix
- If you have screen off issue, reboot can fix temporarily. Or disable boot animation for permanently fix

Re: [KERNEL][27 JAN] [P93x|SU640] Wind_Kernel-v3.0 for STOCK/MIUI ICS

Honestly, I dunno how init.d scripts execute automatically.
But you may use Smanager, select the script, click the "su" and "boot" and then "run"

Hi lyfkevin!
Have some question. What utils do you using for repack boot.img?
I tried different mkbootimg, unpackbootimg, mkbootfs, split_bootimg.pl but it not working. Using stock cmdline and base 0x40200000 but it not loading. I never have this problem before on my old phone. P930 have some specific?

I forgot where did i get this mkbootimg pack.
I followed this thread from HO!NO!
http://forum.xda-developers.com/showthread.php?t=1566202
And I use command to make boot.img
Code:
./mkbootimg --kernel zImage --ramdisk boot.img-ramdisk.gz --cmdline "vmalloc=450M,console=ttyDCC0,115200,n8 androidboot.hardware=i_skt" --base 0x40200000 --pagesize 2048 --ramdiskaddr 0x41a00000 -o testboot.img

Oh! Thanks! I never before not using --ramdiskaddr 0x41a00000

Made stuff for easy life. :fingers-crossed:
Just use extract.bat for extract and pack.bat for packing. Everything working automatic. If need change cmdline, edit make_boot

After installing it on last Miui 3.2.1 i have only 768 Mb RAM, why?

Thanks, I'm testing it now

cm10.1 wind kernel v1.0 released
not compatible to cm10, dun mess up
Currently CPU1 status is a bit weird, but defintely wont affect daily use. IT CAUSES LESS BATTERY DRAIN
I guess there is interference between kernel based mutlicore decision(msm_mpdecision) by show-p1984 and governor Intellidemand by faux123.
Test required.
My approaches:
1. switching cpu0 cpu1 governor
2. disable msm_mpdecision by "echo 0 > /sys/kernel/msm_mpdecision/conf/enabled"
3. try different mpdecision/intellidemand configurations by kernel tunner
4. terminal "su" "start mpdecision"
PLX dun hestitate to report ur feedback as it helps me to improve the kernel

hmm, i don't know if it bug or not, but i stay my phone on idle on night, and after 8 hour i have 31 percent of battery. i hope it's not bug

Sounds like classic CM10.x

I want to say that after 8 hours as it remained 31 percent.
classic cm 10.x? (i don't understand)

I assumed you said it drained to 31% after 8 hours idle... if that's the case, classic battery hogging CM10.
If you meant it stayed at or near 31% after being idle for 8 hours, then Wow... That's pretty impressive.

yes, i mean it stayed at 31 for 8 hours (just idle, without wifi or internet connection).

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

1401600
1516800
1555200
1612800
1804800
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

hello sir, i already tested the performance control on stock ROM and kernel, seems the apps also force close so this problem maybe caused by the incompatibility to CM12

Sir..can i flash this kerenel for liquid smooth(5.0.2)

Here's a step by step instruction to install this kernel:
1. download the above file (via phone directly or to a PC)
2. copy the downloaded zip file to /sdcard/download/
3. Open ROM Manager and select "Reboot into Recovery" and select "OK"
3.*Or use any other method to get into recovery.
4. Once in recovery, select "wipe cache partition", select "Yes", then select "advanced", then select "Wipe Dalvik Cache", then select "Yes" again. Once finished, click the back button to go back to the main recovery menu. On that menu, select "Install Zip From SDCad", then select "Choose zip from SDCard", then go to /sdcard/download and select the downloaded zip file and let it run its script.
5. Once the script is done, select "reboot system now"
Note: After FLASHING, the first reboot may take longer than usual, please be patient... After the first reboot, it may lag during initial load (let everything finish loading). Once everything is loaded and phone is ready for use, reboot the phone a 2nd time and the lag will be gone and everything should be silky smooth...

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.

No. I do mean tap2unlock. http://forum.xda-developers.com/showthread.php?t=2965344
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..

Help and FAQ
THREAD RULES & PROTOCOLS FOR THIS DEVELOPMENT THREAD:
I MIGHT NOT HAVE YOUR DEVICE variant and or able to reproduce your "issue". With this in mind, without providing as much information as possible, and resetting your device to a stable unmodified baseline, any potential troubleshooting or logs could be meaningless. So please follow the guidelines set out below. Thanks
BY POSTING YOUR ISSUES IN THIS THREAD, YOU ARE AGREE TO HELP YOURSELF FIRST BY PROVIDING INFO REGARDING:
Code:
1. DEVICE MODEL ?
2. ROM and firmware version (build number, boot-loader etc) ?
3. EXACT steps taken to reproduce YOUR issue
4. Screen-shots (if applicable)
5. Did you read Posts #1-3 completely?
6. Did you search the thread, XDA or GOOGLE?
7. Did you follow the install instructions EXACTLY?
8. What was your previous kernel?
9. Do you have any other known kernel tweaking apps, scripts or mods? ([B]remove them[/B]). [COLOR="Red"]This includes Xposed etc[/COLOR]
10. Try older kernel (if available)
11. Factory reset ?
12. Try latest stock [B]UNMODIFIED[/B] firmware (without custom ROM - if you have installed) and factory reset
13. Delete your ROM BusyBox (kernel uses it's own in /sbin)
ONLY IF YOU HAVE TRIED SUGGESTIONS ABOVE:
Turn on logging in Synapse and save logs AT TIME OF ERROR. AND post together with ALL the above information.
ELSE, DON'T WASTE MY TIME, YOU WILL BE IGNORED AND/OR POST REPORTED !!
THANK YOU :good:
CAN I BUILD A KERNEL FOR YOUR __XX DEVICE ?
I will not build for any device that I can not compile using SAME source, personally test method or debug. Some device variants can compile with same source.
If you have any of the following, please post your LATEST stock boot.img along with the firmware version you extracted it from.
N920R4​
Download the full firmware package from either sammobile.com or samsung updates.com (1.5+ GB )
"NO UCI SUPPORT"
It's a ROM busybox compatibility issue
Three choices:
Device > settings > applications > Synapse > force close & wipe data and REBOOT
OR
Remove your ROM busybox from /system xbin and /system/bin (Synapse will use the kernel busybox in /sbin).
Force stop Synapse and delete app data (device settings > applications)
Re-flash kernel as per Installation Instructions
OR
Try install a different busybox
Force stop Synapse and delete app data (device settings > applications)
Re-flash kernel as per Installation Instructions
STUCK ON SAMSUNG BOOT LOGO AFTER FLASH
Ensure you flashed the correct kernel for your device model
Ensure your download is not corrupted. Check MD5 hash or re-download
Your current base firmware (ROM, boot-loader version etc.) may be incompatible - UPDATE to latest with Odin and try again.

"Unauthorized actions have been detected, reboot to undo changes"
As it's a common warning found with all KNOX enabled android devices, you would have found the answer by Google search and also that it is actually unrelated to kernel and also unrelated to this kernel development..............
It is caused by the process of rooting/modifying your device. Unless you use KNOX, don't worry.
[Q] How to disable
[A] Freeze or delete your KNOX & Security related apps/processes manually (using root explorer or titanium backup (pro) or use Synapse > Security > disable KNOX
CAN I USE OTHER KERNEL CONTROL APPS
No, many features and options won't be available. Remove all other control apps to avoid conflicts !
Synapse is the recommended and has everything you need
BATTERY TIPS
Try enable some of the CPU MULTICORE features in Synapse (slight performance cost):
Power Aware Scheduling
HMP LITTLE Packing
PEWQ (power-efficient workqueue)
Increase the HMP Up threshold a little
PERFORMANCE TIPS
LATER
RANDOM REBOOT
Don't UV or UC CPU or GPU
Use SkyHigh defaults
Use a stock UNMODIFIED ROM for your device variant
No tweaks, Xposed or other CPU control apps installed

CAN I INCLUDE SkyHigh KERNEL IN MY ROM
Although I do appreciate your contribution here, if you could please do not include my kernel in any ROM package etc. This policy goes for anyone.
Having my kernel distributed outside my development thread just removes a lot of credit and more importantly, constructive user feedback that could be helpful to my development or user issue.
DOWNLOAD LINK NOT WORKING
I want to keep this project all in one place - ☆☆ NO MIRRORS ☆☆
Please try again in a few minutes
POOR CPU/GPU BENCHMARK or GRAPHICS PERFORMANCE
Disable any CPU MULTICORE options in Synapse
Allow the device to cool. Repetitive testing will heat the device hardware and invoke thermal throttling and lead to decreased benchmark.
HIGH CPU/GPU OC >> excessive heat >> thermal throttling >> reduced clock frequency >> DECREASE PERFORMANCE
BACKUP & RESTORE
DO NOT restore profiles from different kernel version
If the backup isn't visible, reboot device and ensure for have "synapse boot completed" message. Otherwise synapse won't read the file.
DYNAMIC MANAGEMENT OF DIRTY PAGE WRITEBACKS
* [Christopher83]
This feature allows to have two different intervals for dirty page
writebacks and to dynamically manage them when the system has been
resumed (it's active) or when has been suspended.
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)
- dirty_writeback_suspend_centisecs is the interval for the dirty page
writebacks when the system is suspended (screen off)
This feature is in part inspired on Francisco Franco's patch:

TCP/IP NETWORK SECURITY
* Thanks to zeppelinrox & V6SuperCharger
Hardening the TCP/IP stack to SYN attack
Bump up tw_buckets in case we get DoS'd
Ignore pings
Don't cache connection metrics from previous connection
Don't pass traffic between networks or act as a router
Enable spoofing protection (turn on reverse packet filtering)
Don't accept source routing
Don't accept redirects

CHROMECAST - STREAMING PROBLEMS
* Thanks to @AtLmd Post
Lock screen MUST be enabled (simple screen lock swipe) I don't know why but it breaks the chromecast app's ability to resume smoothly if switched off
Synapse > Network > DTIM (both screen ON & OFF) = 1
Synapse > Network > WIFI Power Mode (screen OFF) = FAST
