[Kernel][AOSP][4.3/4.4][Linux 3.0.101][TWRP 2.6.3]aidfarh's kernel (updated 13-12-20)

aidfarh · Oct 4, 2013

WARNING!!
This kernel allows you to set the CPU frequency beyond the stock rated frequencies. Do this at your own risk! I will not be responsible for any damage to your device if you do so!

INTRODUCTION
It seems there's a dearth of kernels for JB 4.3 AOSP-based ROM for the i9100g. So I'm deciding to share my own custom kernel for those who want some alternative to the the built-in kernels on the AOSP/CM10.2-based ROMS.
I can't think of a fancy name for this, so let's just call it aidfarh's kernel for now.
Any feedback is welcome.

FEATURES

Based on Mokee v43 kernel, which is based on CM10.2 kernel
Updated to Linux version 3.0.98
TWRP 2.6.3 recovery
USB fastcharge available (disabled by default)
Governors:
1. Ondemand
2. Hotplug
3. Userspace
4. Interactive V2 by imoseyon
5. InteractiveX by imoseyon
6. Performance
7. Powersave
8. Conservative
9. Lulzactive
10. PegasusQ
11. AbyssPlug
I/O schedulers:
1. cfq
2. noop
3. deadline
4. row
Dynamic management of dirty page writebacks
Some optimisations - hard float, some cache optimisations, disabled tracing

CHANGELOG

20131010:

Added 200 & 1350 MHz CPU frequencies. Overclock/underclock at your own risk!
Updated row scheduler to V4 and tweaked default settings.
Modified power.t1.so and included in kernel zip.

20131013:

Prevent omap4 duty cycle from overriding user selected cpu max_frequency.
Optimize cpufreq transition latency.

20131023:

Update to make it work with new multi-sim feature in CM-10.2.

20131113:

Updated to Linux kernel version 3.0.101.
Added SIO scheduler.

20131220:

Android 4.4 (built on Omnirom 4.4 source tree).

20131222:

Released different versions for Omnirom 4.4 and CM11.
Omnirom 4.4 version - fix max frequency behaviour (power.t1.so)

REQUIREMENTS
Android 4.3
This kernel should work with any CM10.2 based ROM. Tested on CM10.2 and Mokee
It would probably also work with non-CM AOSP 4.3 based ROM, but due to differences in implementation, some features might not work 100%.

Android 4.4
I've produced two versions of this kernel. One is compatible with Omnirom 4.4 and the other is compatible with CM11. Compatibility with other Android 4.4 roms is unknown.

INSTRUCTIONS
Flash the zip in CWM or TWRP recovery.

TO-DO

~~Add more CPU frequencies/overclock/underclock~~
Tweak default governor tuneables - suggestions welcome
~~Update ROW scheduler to V4~~
Further optimisations

P.S. For some reason I can't edit the first post. Is there a problem with the server? (Edit: solved by using Firefox instead of Chrome)

Showing some support here...

...are you editing using Tapatalk? I face that from time to time...

You forgot this: https://github.com/aidfarh/android_kernel_samsung_t1/commit/6faac1345139ea7301dd4c98d7bf200b77167a9a

And just a heads up, the last time when I tired to apply interactiveX, I faced random reboots in recovery...

I was using Chrome. After clicking the Edit/Delete button I just got that cursor spinning on and on. Editing using Firefox was fine.

And yeah, I also had the same problem with interactiveX, but that was back during ICS days. The reason was interactiveX didn't coexist well with interactive, so my solution back then was to use only interactiveX and disable interactive. I'll do some more tests and hopefully the newer versions work well.

If it's based on CM10.2 it should be compatible. How about you try it and see?

Woopsies didn't check that on Slim bro sorry. Now flashing this to that other ROM that shall not be named if you get my whiff. Yeah can't find vibration intensity in settings here either if that helps.

Use TricksterMOD...

Slim still uses old code, so until it updates, newer kernels won't have vibration control in Slim...
