Mugetsu is a package for Anzu (SE Arc) ported from Urushi (SE Ray) comprised of:
  1. Custom kernel
  2. Patched libsqlite.so
  3. /sd-ext tools
Given the similarity of hardware between Urushi and Anzu I've decided to test drive a release package for the latter; however, given I don't have a device I'm releasing this without knowing if it will work but I'm very confident it will which has now been confirmed it does by cezarL.

Currently working for:
  • CyanogenMOD 7 (lastly tested with FXP045)

Quick kernel features snapshot:
Code:
version two:
- Increased OC support up to 2.0 Ghz.
- Added support for voice calls recording. (experimental)
- Further optimizations to Deadline I/O Scheduler.
- Lowmemorykiller.c parameters tuned.
version one:
- 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.
Download (SE Arc):
(read the paragraph below)
Everything you need to know about this package and kernel as well as instructions on how to flash and some interesting other stuff, please go to the original thread and make sure to read it thoroughly. Of course, when it comes to downloading the package use the aforementioned link and not the one for SE Ray.

Original thread: http://forum.xda-developers.com/show....php?t=1336375 (Don't post there if you're not a SE Ray user)

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

I'm interested in testing but I can't use CM7 since I need HDMI-out. Would you build one for stock ROMs?
Thanks.

At the moment it's not possible. It's a highly optimized kernel, including a different network scheduler, TCP congestion control and url hashing. While this accounts for a huge boost in internet/market page loading (50%+), it also requires the wireless modules to be recompiled but since FXP wlan source doesn't work with stock and SEMC sources are full of debug and tracing crap, the only option for now is using on stock ROM but without wireless, which is a dealbreaker.

I can confirm the kernel's working on Arc S (with FXP045).
I got all the new governors and schedulers in NoFrills, Market is loading much faster than with default CM7 kernel.

Thanks a lot!

Thanks a lot for officially testing, I'll update the first post.
And yea, I tweaked the hell out of interwebz, it should account for a 50%+ boost in market/internet page loading.

Tried last night but ended up with 'error' when trying to connect to wifi. Was a bit drunk and I think I forgot to wipe usrdata so I'll try again at some point.
