Code:
Settings of The Available Features
partly been taken from Christopher explanation thread - http://xdaforums.com/showthread.php?t=2172148 all credit go to Christopher83 please thank he for prepare this detail of function

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 HurtSky's Kernel the feature is enabled by default and the provided processes white lists are the following:
- donotkill_proc_names = "com.cyanogenmod.trebuchet,com,android.inputmethod.latin"
this means that Trebuchet Launcher,stock keyboard will be preserved from killing
- donotkill_sysproc_names = "android.process.acore,com.android.phone,com."
this means that the system process, the phone process 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

i did not increase the RAM size.. it is default 351mb

BIGMEM make lag. it just a number, no performances increase at all.

Hello, hurtsky.

Can I know, how you make WIFI working? As I extract your kernel, there are no WIFI modules inside it

the modules is inside /system/lib. you can get it inside the zip mate

Thank you for answering, but I don't see anything inside /system folder or I the one who misunderstand here..

friend.. it is in the zip. not in the ramdisk.. since now the module implemented in the ROM

extract the .zip and you can find the necessary module

Thanks, mate. Now, I understand. I don't realised actually the modules in the zip file.

sorry for my silliness.

BTW, maybe it is OT. But it's a good news for us :good:
