SpeedMod, probably the most popular kernel originally developed for the Samsung Galaxy S, is now available for the AT&T Captivate too. XDA member hardcore, the developer of SpeedMod, decided to create the same kind of kernel for the Captivate.
The developer’s aim is to have a kernel that is fast, compatible, stable, and with good battery life. It contains many custom features:
Originally posted by hardcore
- Based on JPX Android 2.2.1 kernel source
- Works on all stock Froyo 2.2 and 2.2.1 ROMs and popular custom ROMs
- 339MB RAM and all features should work
- Enhanced version of sztupy’s Universal Lagfix
- Includes neldar’s BackLightNotification 2.3 from https://github.com/project-voodoo/ba…ernel_patches/
- Sharpness & color fix for UI, inspired by supercurio’s work on Voodoo
- SpeedMod: Replaced kernel jhash2 with jhash3
- Includes my Startup Tweaks from http://forum.xda-developers.com/showthread.php?t=813309
- Adjusted kernel HZ value to (hopefully) balance battery life & smoothness
- Uses BFQ IO scheduler by default, from http://algo.ing.unimo.it/people/paol…ed/sources.php
- Updated ext4 code in kernel from http://www2.kernel.org/pub/linux/ker…/ext4-patches/
- Properly working Tiny RCU patch for better speed and efficiency from http://android.git.kernel.org/?p=ker…90160a18caf95d
- Optimized compiler flags: -O3 -mcpu=cortex-a8 -mfpu=neon -mfloat-abi=softfp
Don’t worry if you don’t understand most of this – we can tell you now that the kernel is really good.
Yet, be sure that you know how to flash kernels to your phone. Otherwise, it would be a good idea to investigate further before doing things that could brick your phone.
Check out the thread for more information and download the kernel.
