EXPERIMENTAL KERNEL

Girando su xda ho trovato questo nuovo kernel per jelly bean 4.1.2 e ho visto che ancora nessuno lo aveva riportato su Androidiani,quindi l'ho fatto io

LINK XDA: [Kernel]Experimental v8.0[JB 4.1.2] - xda-developers

KERNEL FEATURES:

General:
Kernel version 3.0.8
Compiled with Linaro Toolchain GCC 4.8 with Optimizations
Android Logger Disabled(++Performance) (Check HOW TO on how-to enable)
Frandom(Faster than stock random)
Entropy tweaks.
Cleaned off Debug stuff, which slows down the Kernel (FRAME POINTER, Log Buffer Size is 64KB)..
Google snappy driver.
Snappy compression instead of LZO
for Zram swap.
Elf.3 included for better battery.

MEMORY:
SLUB memory allocator
Low memory killer updated to Android 3.4
Logger updated to Android 3.4
Memory compaction
380MB RAM

ARM:
ThumbEE
Build with neon
Enable arch_power by default

MALI:
L2 cache max reads writable
Disable mali state tracking

Network:
Added more TCP Congestion Avoidance Algorithms: Westwood, Veno, Illinios, Vegas. Cubic(default).

Makefile:

[WeedSmoker]

GUIDA:

1)Download Kernel
2) Download Modules
3) Mettere moduls sulla sd-card
4) Flashare il kernel tramite fastboot
5) Entrare subito in recovery e flashare i modules
6) Avviare il sistema

HOW TO:
Qui ci sono alcune istruzioni su come giocare un pò con il kernel.
C'è bisogno del Terminale.
Se vuoi cambiare questi valori,hai bisogno dei permessi di root.
Se esce 'Permisson denied',hai bisogno dei permessi di root.
Se il telefono smette di rispondere,premi il bottone di spegnimento per 8 secondi per riavviare.

(Mali GPU)

Spoiler:

Mali debug level Disabling can speed up a bit Quote: echo 0 > /sys/module/mali/parameters/mali_debug_level * Higher level,more messages will be printed in dmesg,system will slow down Mali L2 max reads control: (Stock:28kb,Default:48kb(max)) Quote: echo xx > /sys/module/mali/parameters/mali_l2_max_reads * Some values will slow down graphics * If not sure,keep default

Frandom Module

Spoiler:

(5.3+)Use CrossBeeder to enable frandom.

TCP congestions

Spoiler:

Supported: Quote: cubic(default),westwood,highspeed,vegas,veno,yeah To check all the available options: Quote: busybox sysctl net.ipv4.tcp_available_congestion_control To change to other option: Quote: busybox sysctl -w net.ipv4.tcp_congestion_control=YOU_WANT_TO

Logcat

Spoiler:

I have made android logger(logcat) as module to free more RAM. Create a new init.d script: Quote: #!/system/bin/sh insmod /system/lib/modules/logger.ko Then you can use logcat command.

EGL Driver

Spoiler:

To use Mali hardware egl driver only: Edit /system/lib/egl.cfg Quote: 0 0 android 0 1 mali To Quote: 0 0 mali

Init.d script

Spoiler:

Please install busybox in system first I recommend you install busybox via apps Create a new folder named 'init.d' in /system/etc Set the permisson of init.d foler to 0777(rwxrwxrwx) (at least has read and exec permission) Set the owner to 0.0 (root root) Put some scripts (any name you like) in init.d folder with permisson 0777 (rwxrwxrwx) (at least has read and exec permission) Scripts with right permisson will be runned when system boots.

zRAM SWAP

Spoiler:

[zRAM] zRAM is optimized for Android. It is not lazy anymore. Using zRAM will take a little CPU,because it needs to compress/decompress memory. Setup disksize first: (example: 96mb= 96×1024×1024) Quote: echo 100663296 > /sys/block/zram0/disksize * Lager size more RAM will be compressed. Enable: Code: Quote: mkswap /dev/block/zram0 swapon /dev/block/zram0 To check how many does it use: Quote: cat /sys/block/zram0/num_reads cat /sys/block/zram0/num_writes * You can get other info in its sysfs [SWAP] Format/resize your SdCard via computer first. Enable: Quote: mkswap /dev/block/mmcblk1p1 swapon /dev/block/mmcblk1p1

Sto montando questo kernel da ieri...E' fantastico!

Fixed Camera? Funziona la fotocamera frontale??

No,la cam frontale non funziona comunque...

È normale che abbia la RAM così intasata? Si rallenta a morte. Mon ho usato la guida per i moduli, e uso ondemand con noop

Screen?

Io di solito avevo tra i 130-90mb liberi,interactive e vr

Cambiando governor e scheduler naturalmente non cambia nulla, riguardo gli impuntamenti...
Nei (rari) momenti migliori arrivo a 80mb, altrimenti sto sempre sui 30-40 che sono un po' una fogna...

[thebrutal]

dovresti mandare lo screen non solo della cache ma anche dei servizi in esecuzione, così non ha senso
