[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] knzo:
Mugetsu is mainly a custom kernel based on FXP's source up until 3/11. The credit of every work prior to this date, as well as providing the wlan source needed to compile wireless modules, belongs to FXP team. I've just tweaked and messed a bit in order to optimize performance, internet speed, battery and memory management, while keeping it as light as possible.

Currently working for:

CyanogenMOD 7 (lastly tested with FXP045)

SEMC 4.0.2.A.0.42 *

MIUI (lastly tested with MIUI 1.10.21)

* wifi is broken since I'm unable to compile wlan modules for stock

Features\Changelog:

[I]version two[/I]:
- Increased OC support up to 2.0 Ghz.
- [URL="https://market.android.com/details?id=com.skvalex.callrecorder"]Added support for voice calls recording[/URL]. (experimental)
- Further optimizations to Deadline I/O Scheduler.
- Lowmemorykiller.c parameters tuned.
[I]version one[/I]:
- Bumped version to 2.6.32.18
- Overclock support up to 1.6 Ghz
- Tiny RCU (+ optimizations)
- SLQB memory allocator
- Many new CPU freq governors (+ optimizations)
- Many new I/O schedulers (+ optimizations)
- Bumped BFQ to last version
- Support for CPU unaligned access
- Veno TCP Congestion control *
- Stochastic Fair Blue network scheduler *
- Bumped jHash to last version *
- Improved RWSEM algorithm
- Improved CRC32 algorithm
- Disabled swappiness
- Increased Config_HZ
- Increased data transfer rate
- Sysctl and lmk tweaking
- Stripped of unnecessary crap. So you have an idea, stock kernel has 3.2 MB, FXP has 3.0 and this one has 2.6 MB.

* huge internet/market page loading boost

CM version is updated to the latest build so it has wifi, haptic feedback and vibration working.

SEMC has an insecure boot.img so it can be rooted with SuperOneClick and I've also added CWM recovery.

Available modules:

- TUN
- CIFS
- Powersave governor *
- Performance governor *
- Logcat

* since powersave lowers cpu max frequency to same value as the min frequency and performance the other way around, these just seem kind of irrelevant when you have cpu sliders; however, I've included them as a module for advanced users

For activating a module, run this command on terminal: insmod /system/lib/<module.ko>

You may want to add afterwards a line to a init.d for automatic insmod.

Available governors:

- Ondemand
- Conservative
- Interactive
- InteractiveX
- Smartass2 *
- Smoothass
- BrazillianWax
- SavagedZen
- MinMax
- Scary

* default

For choosing the governor use CM settings > performance, SetCPU, ROM Toolbox or any other app.

Available I/O schedulers:

- Noop
- BFQ
- CFQ
- Deadline *
- Simple
- VR
- Anticipatory

* default

For choosing the I/O scheduler use No-Frills app or the following command:

echo "scheduler-name" > /sys/block/mmcblk0/queue/scheduler (cat this path for the names)

Download (SE Ray only):

v1: SEMC 4.2.0.A.0.42 - 414c02bb24712eec04e92d1ec858c9f0 || CM/FXP - c058878d24f90871ee808e18c3f6b8f1 || MIUI - (check in MIUI thread)

v2: removed for giving wifi problems to some people.

Instructions:

Download the package.

[CM7] Copy the package to your microSD card.

Extract boot.img from it.

Boot your phone into fastboot mode: turn off, plug USB cable while holding vol+ (blue light).

Use fastboot tools to flash the kernel: fastboot -i 0xfce flash boot boot.img

Unplug cable, turn on phone.

[CM7] Keep hitting vol- while the phone is booting to get into CWM.

[CM7] Flash the package in CWM (flash zip from sdcard).

[CM7] Reboot.

[CM7-Optional] Read about /sd-ext tools.

I'll try to update it as frequently as I'm able to but don't be expecting much, I don't have much spare time and this is only a hobby for me; I'm not a computer engineer, I do this mainly for myself and to keep the brain sharp and always learning.

If you go back to another kernel (boot.img) you may find yourself without wireless if you're using CM.

In this case, just flash this in CWM, no wipe required: http://www.multiupload.com/LIX7E96BGX
