[Kernel][ION][CM11] Just Another... Stage 7.3 (18/12/2014)

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.

Kernels - based on new KK2.7 CAF-Branch provided for samsung msm7x30 devices by Christopher83 & arco68:

Should work with all roms based on arco's latest unofficial CM11 from 20141029 and 20141210:

18/12/2014 JAKStage7.3_UV_416MB_3.4.105+inittweaks

11/11/2014 JAKStage7.2_UV_416MB_3.4.104+inittweaks

Old Kernels, not recommended anymore:

Installation:

flash the kernel
wipe cache partition
wipe dalvik cache
reboot twice and enjoy

Have fun

I guess not. I have to ask madridii if it is possible.

This kernel has trim support?

No trim support yet. Im going to talk to sir mordred first, maybe im going to push one the next days too.

did you plan to make bigmem version too? thank you sir! :good:

Great job mate @tycoo

op updated with trim supported kernel. Thanks to @sir mordred

which kernel use for mokee rom ?

kiul said:

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

dodora3d said:

I guess @theloneseeker has to modify my kernel or to explain me what to do.

theloneseeker · Jun 4, 2014

@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:

tycoo · Jun 11, 2014

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

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
