So, who has cajones that clank?

Current things of interest:
- Overclock up to 1.6ghz [Use a tool such as Setcpu to overclock]
- 2.6.36.4 kernel base
- CIFS included
- TUN built-in
- NTFS support
- Voodoo Sound

All sources can be found on my github (see signature)

These are designed to be flashed via clockwork, or you can flash them via Shinzul's Kernel Manager (Available on the android market)

Disclaimer: You flash these at your own risk, and assume any and all potential consequences, including (but not limited to), loss of data, meltdown of your device, world destruction, injury of assorted puppies, spoiling of your glass of milk, revocation of chocolate privileges...etc. In all seriousness, it's an experimental kernel, so treat it as such, and enjoy.

Overclocking disclaimer: Overclocking is never guaranteed to be stable (that's simply common sense). If an overclock speed is not stable, your device may not be able to handle it and you should try a lower speed.

BE SAFE!!! MAKE A NANDROID BEFORE FLASHING SO YOU HAVE SOMETHING TO FALL BACK ON

Current version: Netformer 1.6 (For Honeycomb 3.2) [Also available in Kernel Manager, from the Android Market]
Netformer 1.6

Tested with Prime 1.7

Code:
Changelog:
Revision 1.6:
- Updated for Honeycomb 3.2
- Due to some rather large changes by ASUS in the kernel, the tap-to-click disabler app currently will not function in this latest kernel. If it is possible to bring the functionality back, it shall be done.

Revision 1.5:
- Updated to support android 3.1
- Added Voodoo Sound
*Your quadrant epeen may not be quite so large (though they may be more accurate) due to some bug fixes from upstream, if there is room for improvement, it will be explored*

Revision 1.4r2:
- Fix a bug causing wifi to break when the tablet sleeps

Revision 1.4:
- Add SLQB memory allocator
- Set timer to 1000hz
- Add 1.504 and 1.6ghz frequency steps
- Add preliminary toggle interface to allow tap-to-click to be disabled (See OP for a nice gui front-end for the toggle, courtesy of vividboarder)

Revision 1.3:
- Assorted bugfixes, including a possible fix for a bug that could lead a cpu core to 'forget' it's speed policy and wander out of sync

Revision 1.2:
- Power regulator bug fixes that may address the "SoD" issue experienced even by users on the stock kernel 
   (technically not actually a sleep of death)

Revision 1.1:
- Adjusted voltage levels for stability
- Added NTFS support
- Assorted bugfixes

i see the OP says it is designed to be flashed in cwm, i was under the impression that kernels had to be flashed as a blob through adb. is that no longer the case?

I'll wait a little longer, but I'm glad to see kernel development picking up :p thanks netarchy.

P.S. on stock kernel what is the lowest freq the transformer goes to?

    I'm apparently one of those who doesn't have any issues; just flashed Netformer 1.5 over new Prime 1.6 again, no issues whatsoever.

    Question to netarchy if he ever checks out the thread:

    Do you think we can add some other improvements?

    - ext4 no journal filesystem options
    - noatime, nodiratime (is it already there? not sure)
    - jhash3 instead of jhash2
    - HZ value (what's the current one I wonder? 500Hz was the best for SGS, made things look much smoother)
    - what codesourcery are you using? 2010.09 seems the best
    - new tiny RCU
    - remove debug logging

    Just throwing in some ideas.

    EDIT: noauto_da_alloc is a good idea too for ext4. Also, no journaling at all might be a bit of overkill but data=writeback instead of default data=ordered should speed it up by quite some value.

    The ext4 mount stuff is already a default even in stock.
    Last I looked tinyrcu did not play well with smp
    Debug stuff is already removed
    jhash3 is planned, I just haven't gotten around to adding it
    HZ is currently at default (100), a brief trial at 1000 revealed problems I haven't had a chance to correct before playing with the config option again.
    When I use codesourcery, I use a newer build (based on gcc 4.5.2) than what you reference (which I believe is a gcc 4.5.1 release), but usually I use a toolchain I built on my machine.

    I know there appears to be a lack of attention from me lately in the tf forums, but I assure you that I'm still watching and I have plans for the kernel (I do love my TF after all ;D).

    Hey Netarchy,

    Would it be possible to see a Netformer version with updated Voodoo Sound? Last version of voodoo control app says the kernel module is outdated. Thanks!

    Soon™

    Especially with the 3.2 update hitting now, no doubt there will be some small delay before asus drops updated kernel sources, and then balls to the wall. ;D
