[Kernel] ardatdat kernel v1.5 [CWM] (OC/ROOT/VR/3G/init.d) (2012-02-05 13:00GMT)

Happy New Year of Dragon !!!

The first wonderful kernel for Galaxy R in the year of dragon comes out now!

Change log in v1.5:

- Remove lagfree governor as it seems to cause some laggy behavior
- Put back 608Mhz frequency
- Increase stability & improve smoothness by reverting some commits in v1.4
- No worry, keep the 3G/wifi counter fix!

(v1.5 is a quick fix for v1.4 and if you have already flashed v1.4, please skip it and jump directly to v1.5. Thanks)

Change log in v1.4:

- 3G counter fix: fix the 3G counter problem. Now you can measure the data in/out using your favorite software! (e.g. 3G watchdog)
- Add support to load any scripts located in /system/etc/init.d/ upon booting the device
- Patch up to the newest ZCLA1 kernel source as released by Samsung open source
- Allow more finely control on the brightness level (you will feel it when you slide to control your brightness)
- Add a new frequency: 960Mhz (it is good for daily use)
- Remove the frequency: 608Mhz
- Added new lagfree CPU governor (You can now turn off 'profile' in SetCPU and use the lagfree governor)
- Use the optimized Linaro ARM Cross toolchain for compilation
- Added the VR I/O Scheduler (make default)
- Enable SWAP support
- Cherry picks several commits from CyanogenMod LGE star kernel
- Makefile optimization
- Compatible with almost any android version 2.3.4/2.3.5/2.3.6

*** Noticed that after flashing this version, your screen brightness will go dimmer.
But now, you can fine tune the brightness level in the brightness setting.
Just slide through the brightness control bar and you will feel the different. ***

The introduction of lagfree governor is funny here. It will go up to the max freq. easily, but it will go down very slowly in nearly every 10 seconds. The purpose is to reduce the number of changing in frequencies. To make good use of it, disable any 'profile' in SetCPU. If you don't like the lagfree governor, just use back the 'interactive' one.

Special thanks to: CyanogenMod, intersectRaven, pershoot, faux123 for their kernels and references.

If you have press 'thanks' in the first post, you can say it again in the post #2

Updated at 2012-02-05:
v1.4 have caused some laggy issues on some machines. I am going to take down the v1.4. Please wait for my next version v1.5. Stay tuned!

Finally, flashing any kernels or ROMs have risks! Flash them at your own risk!

Old version:
==============================================================================

Happy New Year 2012 !!!

As the new kernel is flashed using CWM Recovery, I make a new thread here for it.

The new kernel, based from ZSKK5 is compiled. I make it flash-able by CWM recovery. So, you must install CWM in order to flash this kernel. (Guide: http://xdaforums.com/showthread.php?t=1406541 Thanks s4sixty & legion1911.).

Below are the details of the kernel:

Features
=======
- For Samsung Galaxy R (i9103) only
- Based on Samsung open source, ZSKK5 kernel
- Now support auto-rotate in ZSKK5 ROM
- Added new frequencies: 1200 & 1350Mhz
- Setting of max 1350Mhz through SetCPU
- All stock frequencies are untouched: 216-1000Mhz
- Limit the boot up frequencies to be 216-1000 to avoid unstable boot up
- SetCPU voltage adjustments
- Interactive governor patches
- Add autogroup scheduling feature: automated per session task groups
- Simple IO Scheduler (make default)
- 2.6.36.4 patches
- Speed up framebuffer copy
- memory copy macros and functions fine tune
- Misc. kernel fixes
- Rooted (embedded su & Superuser.apk)

*** I will keep updating this kernel to make it better and better ***

*** Finally, flash at your own risk ***

Tell me if you need a Odin3 flash-able package.

My kernal version is 2.6.36.3-I9103XWKI5-CL577705root@DELL86#3.......with baseband I9103DDKH4.....will the above procedure work on my phone

Yes, it should work!
Make sure to backup thru CWM. You can always rollback in case

Thanks for your testing.

I observe that the reason maybe due to the 'autogroup' scheduling being used in this kernel. Maybe it is the reason causing the variations. I may later release a kernel without autogroup patches and see if it will become more stable.

Thanks ardatdat! I'm testing it in a minute ! Good job with .zip version!

EDIT: My first observations (2.3.6 KK5):

1)Benchmarks

Benchmarks' results are (compared to the odin version = 1.35 vs. 1.3 ghz) generally lower, and statistically more spread out. I mean with that:

quadrant: once you get 3100, another time 3990, third time 2700 (even 1900) - (on 1.35)

smart bench: productivity index is slightly lower (but no big difference 4450 vs. 4560), game index is much lower (2600 vs ca. 2900)

Linpack (I think it's the most trustworthy benchmark): this shows really good results and huge progress compared to stock. But even here (single test) you can get over 50 on one and 17 on the other hand.

Antutu: results generally lower, but very close.

Devices react different on OC, so it doesn't mean that anybody else will notice the same. But I think that in my case the older version was slightly more stable. Standard deviation was lower, but maybe it's just the frequency...

I keep testing...

An updated version without autogroup scheduling is updated in post #1.

Also, the ODIN3 flash-able version is also uploaded.


Please test whether v1.3A is more stable.

what is the difference between this two versions and what is autogroup or without autogroup

Only difference is with/without autogroup

autogroup is a kernel patch. You can search more on the internet.
