STeVEs Custom Kernel and ROM for YP-G1 (Galaxy S WiFi 4.0 EU + USA Version)

[susanggongjja]

Can anyone confirm if using this kernel drains battery faster than the factory one?

I use the custom kernel, but I don't experience any more battery drain than the stock. I don't think that Voodoo sound patch uses up more battery because it's a software tweak that unlocks the potential of the wm8994 DAC, but does not make the CPU work harder. Clockworkmod is also just a tweaked recovery with more features, which does not use more CPU.

generally no noticeable increase in battery usage unless your like me and use voodoo sound to increase the max volume (I run at max to the aux input on my car stereo) then you will see an increase in battery drain.

Version 3.0 released. Enjoy!

Thank you SteveS!!!

Your work is very much appreciated.

I just installed your 3.0 kernel on my EU device.

BTW, I found much easier to install through SGS Kernel Flasher:

Awesome work.

USA version successfully installed. Seems stable etc. so far. I can also confirm that we can now reset to the Recovery menu and it will NOT cause a bootloop! Very nice.

Did that really work? Wonder if it would work on the U.S.

It does. That's how I've always done it.

When I ran Zepplinrox's kick ass kernelizer script, I noticed all the schedulers are set to sio except for mmcblk0, mmcblk1, stl10, stl11, which are set to deadline. Did you find deadline to be better for those?

STeVE's Kernel 3.0
-Based on STeVE's kernel 2.1
-Added all major cpu governors (interactive, interactivex, smartassv2, lazy). Interactive is now the default one for good responsivity
-Added all major I/O schedulers (sio,v(r),bfq,...). SIO is the default one
-Maximized SD card read speed with read ahead
-Init.d script support (Klin's patch)
-Overclock and undervoltage support
At default, no overclock is applied. Kernel is tweaked for good battery/performance ratio. If you want you can tune your parameters using SetCPU (available on market) or similar programs.

Steve,

May I ask, what were the cpu governors on your 2.1 kernel?

I'm curious because with 3.0 I'm getting noticeably worse performance on 3D games (hiccups, stalls etc.). I wonder what settings to use in SetCPU to make things smoother with 3.0. Thanks.

I'm pretty sure by default they are cfq. You can use tegrak to pick which one you want (there are other programs that do it, too)

In 2.1 the default governor was on demand. On 3.0 is interactive but you can choose what you want, there are many available. Just install one of the many apps available

What is the likelihood that this could be adapted to the new 4.2?

I know it's probably too soon to ask, but ... just thought I'd try I understand completely that any & all answers are completely non-binding! I'm mostly just curious if anyone is even thinking about it right now.

Yes it's definitly possible but we would need the source and the initramfs of the actual device.

Understood. Thanks for the reply!

hi thanks for your efforts!

Does flashing this require root?

if so, how do you root the SGP 4.0?

Flashing does not require root but it is better when your device is rooted. (for voodoo sound for example.)

EDIT: NVM, got it.

Sry if this was asked already. I'm a total android-noob.

Is a ROM = OS like Android 2.3.7 etc?

Is this the right order if I want Voodoo Sound and the latest possible Android OS for the YP-G1?:
-rooting with easy rooting toolkit
-flashing kernel, for instance steve's or TerraSilent
-flashing ROM, for instance Rennaissance or Klassik's
