Voodoo sound in the last version doesn't need to be put in the kernel.
There's an option to load the voodoo module while rebooting.
That was the main advance. And that was the prime user option (the "commercial version" of voodoo sound called voodoo sound plus)
But voodoo sound plus is now free.

Thanks for reply.

Does the lagfix will transform my SGS in performance?

With Lagfix, cause it a drain battery ?

If I believe what I read, the most significant gain in performance was in the first versions of android (2.1 and 2.2).Some people says that with gingerbread they don't feel the difference with or without the lagfix. Since the lagfix exist I use it and never stopped so I can't say if I feel the difference.

In my opinion I don't think that lagfix can cause a drain battery. It is just converting RFS format into EXT4. It's just like that you change your USB key format from fat32 to NTFS... I don't think it takes more energy to the system to search and use files in EXT4 than in RFS.
I think that if EXT4 is a little faster (that's why it is a lagfix) it probably uses a little less energy.

That's my opinion as a user. Devellopers can have another opinion with good arguments

This mod is really working, just now I flashed my stock JB. Now I can play Eternal Warriors 2 smoothly without any lag whatsoever. Thanks!

Just wanted to ask something.

I am thinking of trying out SpeedMod kernel, but I saw that logger was disabled in kernel. Now, what I would like to know, is logger disabled , or is it build as module ?

EDIT: Found my answer in the patch set.

hello friend, would you encourage you to do an updated kernel for CM7? We are doing several projects in HTCMania on that basis. thanks

Sorry for the late answer. I dont have time with my school work (this is my last, and most important year at school).

Also, I believe the stock CM7 kernel was a prebuilt kernel, which wasnt updated while building the ROM itself (i.e not using Inline Kernel building).

There are these files: "initramfs-s1-k17-2.tar.zip README.txt speedmod-k17-2.patch"

    Hi guys,

    This is the SpeedMod kernel for Gingerbread.

    SpeedMod's core features are:
    - Super stable: No undervolting, overclocking or potentially unstable modifications
    - Fast and smooth: Compiler and code optimizations
    - Excellent battery life: Remove unecessary logging and debugging

    The K16 series works on older Samsung 2.3.x roms.
    The K17 series only works with the latest Samsung "Value Pack" 2.3.6 ROMs like XXJW4 / XWJW8.

    >>> CLICK HERE for more info and DOWNLOAD links.

    >>> CLICK HERE for the Frequently Asked Questions list.

    This kernel is for the International Galaxy S GT-I9000

    This kernel has only EXT4 LAGFIX support. Please UNDO OTHER LAGFIXES before flashing this kernel.

    Current features:
    - Neutral / Cold (+Blue) / Warm (+Yellow) screen color options
    - Bootanimation support (ROM support required)
    - RFS / EXT4 filesystem conversion and unfragmentation support in CWM
    - CPU governor tweaks: increase responsiveness
    - CWM2.5-based recovery
    - MDNIE Sharpness fix for Pentile matrix and color tuning
    - FM Radio sound fixes based on Voodoo Sound
    - TinyRCU
    - Volume level fixes
    - IO and read_ahead tweaks
    - Disabled Android Debug Logger / logcat
    - Disabled kernel debug logs / printk
    - Updated to jhash3
    - 364MB RAM (K17 series)
    - Improvements to sound quality: 128x oversampling, disable DRC and de-emphasis
    - Microphone recording levels using Voodoo Sound "Balanced" preset
    - Compiled with optimizations using Linaro toolchain
    - init.d, CIFS, TUN, IPV6 Privacy support

    Source code and related files are in the 2nd post.

    NOTES about CWM:
    Use POWER to select and BACK for back.

    Wow, it happens that I live in a different timezone, wake up to see about a hundred posts debating about GPL and the thread is locked.

    That was a bit too much politic-ing for comfort, imo.

    Let me just make my points:

    1. It's been less than 24 hours since the first "demand" for source code was posted. I don't check XDA forums all day - I still go out, sleep and generally do other stuff. I think we should not over-react within such a short period of time, taking into account this website has a global audience living in different timezones and people here have a life outside of the forums.

    2. The Gingerbread version of my kernel is still a test release, I've barely been using it for 2 days and there have been bugs. I normally only release the source to a new version when it's out of the testing phase.

    3. The sources for the Froyo version are published, and whenever I have free time I will try to port over the code bit by bit. If other devs really want to know what I am doing the Froyo sources are available. I will be more than happy to explain certain changes I've made, time-willing and if asked politely.

    I'd like to thank the people who understood the situation and tried to explain it. Let's move on and get back to the usual business of kernel hacking. :)

    K16-10:
    - Scheduler patched and tweaks adjusted
    - Cleanup to kernel configs

    This version is much smoother than previous ones. :)
