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

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

su
echo "<put ur own frequency here>" > /sys/kernel/msm_limiter/resume_max_freq

example:-

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

su
echo "<put ur own frequency here>" > /sys/kernel/msm_limiter/suspend_max_freq

Table of our devices frequency

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

su
echo "you choice of logger mode" > /sys/module/logger/parameters/log_mode

Example

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
*/

su
echo "you choice" >/sys/kernel/sched/gentle_fair_sleepers

Example

su
echo "1" >/sys/kernel/sched/gentle_fair_sleepers

i think this is a mistake

 

[hurtsky]

i think this is a mistake

thank you for letting me know

 

[SkyLaci]

Thanks!
where can i find the performance settings in cm12?

 

[gabriel248]

Thanks!
where can i find the performance settings in cm12?

Its not implemented by the cyanogen-team yet.

 

[xSmart007x]

i get fc with performance control after flashing

 

[hurtsky]

i get fc with performance control after flashing

sorry for late reply, i had trouble to open xda for long time.. i will try to solve the problem in next version.. thank you

 

[riyosakura]

Is it working with the latest build?

 

[hurtsky]

Is it working with the latest build?

nope.. wait for next update.. still busy right now to update the kernel

 

[hurtsky]

sorry for late reply, i had trouble to open xda for long time.. i will try to solve the problem in next version.. thank you

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

 

[SGW★Magic]

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