in allegato trovate lo script per ripulire il kernel prima di istallarne uno nuovo

Highlights

Initramfs from LA2
Samsung kernel-update3 (patched for deep sleep fix)
Based on Arighi sources (arighi) + a LOT of patches included by pongster for performance, stability and battery life
Custom ClockworkMod Based Recovery v5.0.2.7 by AF974 based on Team Overcome Recovery (thanks to alterbridge and AF974)
Instant root (modded script by gokhanmoral of SiyahKernel with a few edits by pongster to ensure latest SU apk and binary are used.)
Newest Superuser 3.0 and su binary (thanks to chainsdd)
Touchscreenfix set to "3" (vitalij)
Init.d support
VooDoo Louder Support by supercurio
2nd Core and Touch Move by Tegrak Support
SetCPU and Voltage Control Support
Full CWM Manager 3.0 Support by Chainfire
CPU & GPU Overclocking and Undervolting by Netarchy
Highly Experimental Ondemand based CPU Governors (Minor Edits only/Renamed to keep bugs on the experiments) based on arighi's deep_sleep and fast_start commits
Maximum CPU Freq set at 1.5Ghz
Enable or Disable File Syncing (fsync enabled by default)
CFS Autogroup by Mike Galbraith Enabled
CPU Topology and Sched_MC enabled
AFTR and LPA enabled
A lot of tunables via sysfs included
Undervolted Int ARM and Touch LED Values (thanks to Phenomenal for the idea)
Git Implementation of SHA-1 for 12% faster boot time
CPU set at 1.2Ghz at Boot for faster boot time (Thanks to Imoseyon)
XZ compressed kernel using optimized values for the size of the kernel
Uncompressed Initramfs (tweaked scripts/gen_initramfs.sh)
NTFS Read/Write Support for OTG (Flash Drives and External Hard Drives with enough Power supported)
CIFS and FUSE Support | Tweaked Ext4 Filesystem
SIO | noop | deadline | V(R) (tweaked for better throughput and balanced latency for Mobile NAND based devices)
sleepy | hyper | conservative | ondemand CPU Governors
generic cpufreq range regulation (arighi) | BLN support (Thanks to creams and neldar) | Fuel Guage Wakelock fix by Entropy512

Power Saving Features:

AFTR + LPA enabled
sched_mc enabled
ARM CPU Topology enabled
CPU Hotplugging OFF when screen off enabled (Thanks to arighi)
RCU Fast No HZ enabled
Stable Voltage Tweaks for Internal Voltages (not ARM Voltage which remain stock) to help lessen heat when in heavy usage scenarios

Boot Time Features:

Used git Implem of SHA-1 for 12% Boot time improvement
Added [PATCH] arm: remove "optimized" SHA1 routines by Linus Torvalds <torvalds@linux-foundation.org>
Added [PATCH] arm: remove stale export of 'sha_transform' Linus Torvalds <torvalds@linux-foundation.org>
Uncompressed initramfs (since initramfs is compressed as part of the kernel image, this is reduced to a copy operation from a decompress then copy one)
Set Clockspeed at 1.2Ghz at Boot time to ensure all critical tasks have enough power to perform them while the governors/maxfreq isn't set yet. (Thanks to Imoseyon for this hack)

CPU Features

CPU and GPU OC/UV thanks to netarchy/Hacre

CPU Governors Included:

Final Clean up of CPU Governors available for simplicity. (all Governors are tweaked for the best possible balance of battery and performance with a slight lean towards performance) With this focus on simplicity stated earlier, the only governors available are the following:
sleepy (ondemand based cpu governor with minor edits by pongster) loves to sleep and idle at the lowest set frequency, hence the name change from "solo" to "sleepy". Its closer to ondemandx in terms of performance. This can be tweaked and tuned using init.d scripts as well.
hyper (ondemand + suspend freq setting ability with minor edits by pongster) This was formerly the original kenobi which I renamed to hyper as others may not get the Star Wars Reference. It gives a good balance between battery life and performance. Its closer to ondemand in terms of performance. also tunable using init.d scripts.
conservative (good battery savings by default due to its slow ramp up and ramp down but tunable for performance) defaults are slightly tweaked for better performance than default conservative.
ondemand (old reliable thats been tweaked by arighi to support deep_sleep and fast_start) these features try to detect if the CPU is coming from a deep sleep and is more likely to sleep again and thus limits its frequency to the lowest possible that can handle the operations needed. fast_start checks if the CPU needs more "ooomph" and jumps to the highest frequency faster to enable it to complete the operation the system needs to complete. (like during boot-up)

3rd Party Kernel Apps Support

CWM Manager 3.0 (It works well for me. Its a useful app by Chainfire that extends the features of the current recovery. No need to reinvent the wheel, so to speak)
Voodoo Louder by supercurio
Voodoo Display (for future supercurio app)
2nd Core by Tegrak
Touch Move by Tegrak
SetCPU by michaelhuang
Voltage Control by xan

Filesystem Features (loaded by default to prevent the load insmodding at boot will cause, however minor)

CIFS
FUSE
NTFS

Experimental NTFS automount for OTG devices (you'll have to do a little more work to enable sdcard as ntfs) (Thanks to gokhan for the hotplug script as base.) This script uses the native NTFS RW support available in t he kernel instead of ntfs-3g
Ext4 Tweaks from 3.x.x branch:

[PATCH] ext4: fix ext4_end_io_dio() racing against fsync() from

I/O Schedulers

SIO (2012 0.2 version)
deadline (tweaked for Flash)
noop
V(R)

Performance Patches

Mike Galbraith's Ultimate CFS Performance Patch (CFS Autogroup)<efault@gmx.de> as ported by faux123 <reioux@gmail.com> for 2.6.35 kernels. I (sarcastillo <sar.castillo@gmail.com>) additionally edited some things in sched.c to make it compile properly for 2.6.35.14 Samsung Sourced kernels*More info on this here: https://lkml.org/lkml/2010/11/20/91

Added the CGroup PatchAdded [PATCH] cgroup: Provides a way of tasks grouping by timer slack value by Kirill A. Shutemov <kirill@shutemov.name> Based on patch by Jacob Pan. Introduces per cgroup timer slack value which will override the default timer slack value once a task is attached to a cgroup. It's useful in mobile devices where certain background apps are attached to a cgroup and minimum wakeups are desired.

Miscellaneous Patches

Added [PATCH] cpu-hotplug: Add the function 'cpu_hotplug_inprogress' by Maya Spivak <mspivak@codeaurora.org>
Added [PATCH] printk: Don't allow cpu to get console lock during hotplugging by Maya Spivak <mspivak@codeaurora.org>
Added [PATCH] rcu-tree: Check for extended quiescent state at start of gp by Maya Spivak <mspivak@codeaurora.org>
Added [PATCH] sched: Do not block when waiting to free old root domain by Maya Spivak <mspivak@codeaurora.org>
Enabled fsync disabled (can be disabled by doing an echo "1" > /sys/module/sync/parameters/fsync_disabled in a terminal emulator or as a script for gscript or scriptmanager)
Touchscreen fix set to "3" for more responsiveness during games, etc. (Thanks to vitalij)

Custom CWM Recovery made by af974 (Huge props to him!) based on Team Overcome Recovery (Huge props to them!)

Enabled back key
Enabled Power button to select (less chance of double pressing the Home Button and format sdcard fro some users)
Reorganized, Inutitive layout and more Readable menu
No/Yes Selection Tweak (If you know how to get to Recovery, you don't need that many "No's")
Mount Internal AND Mount External from Recovery (We figured this would be quite Useful)

Pessottino lo stai provando te ???

[masterdoo]

Questo kernel lo sto provando proprio ora e mi ha dato dei rallentamenti nell'app drawer di adw launcher pero ora pare che non dia piu problemi...Anzi lo trovo buono come kernel soprattutto per i suoi bassi consumi!

Inviato dal mio Samsung Galaxy S II con CheckROM RevoHD V4

[pessottino]

si..l'ho messo ieri sulla immagine in firma dopo che me lo avevano segnalato...ne parlano bene...e onestamente la batteria sembra non esaurirsi mai!

[danybg]

Mi ha battuto di poco maledetto ahahahahahahah stavo facendo io il post........io gia in test.

[Francys-t]

Ma e possibile flasharlo su qualsiasi Rom Aosp?


Inviato dal mio GT-I9100 usando Androidiani App

[edwardeutsch]

Eii e a me non va nessun merito! Ahahah scherzo ovviamente! Grazie per il topic pessottino!

Non date retta ai benchmarks eh! I risultati sono bassi proprio per volere degli autori! Date un occhio alla sezione domande e riaposte sul thread xda! Dei geni!

per favore mettici qualche descrizione delle caratteristiche ... così è pittoresco ma un pò poco esaustivo
