[KERNEL] SIRI Kernel [RC-4][JB]

SIRI Kernel RC-4 per Samsung Galaxy S Advance​

SIRI Kernel, creato dallo sviluppatore di xda, Adi_Pat. Una variante al CoCore o all'Omega kernel, ottima fluidità dopo e buona durata della batteria. Molto simile al CoCore 6.8, reputato da molti (e dal sottoscritto) uno dei migliori custom kernel in circolazione.



Caratteristiche

Anticipazione (Spoiler)

General Features
Updated to LATEST Linux 3.0.65
Compiled with Linaro Toolchain GCC 4.6 with Optimizations
Cleaned off Debug stuff, which slows down the Kernel (FRAME POINTER, Log Buffer Size is 64KB)
Hacks to improve battery! (Disabled SVNET Wakelocks, Removed APE Request from vibrator driver)
Optimized CRC32 Algorithms
Optimized Filesystem Mounts for better Disk I/O
Code rewrites whereever necessary.
Charger Current Control! (Refer to FAQ!)
Sound Boost Control! (Refer to FAQ!)
Android Logger Disabled(++Performance) (Check FAQ on how-to enable)
Lowmemory Killer and Logger updated to Android-3.4
All Section Mismatch Warnings fixed, since they could cause bugs.

ARM Specific Features
ARM specific optimizations and other compiler optimizations
Optimized ARM RWSEM Algorithm
Enabled ARCH Power and Disabled GENTLE FAIR SLEEPERS
ARM: Add optimised swahb32() byteswap helper for v6 and above
Removed Force Upload Mode (Causes A forced Kernel panic when you press Volume down + headset jack plugged in)
REMOVED ALL OF SAMSUNG's DEBUG CRAP which slowed down the Kernel!
Freed the Kernel of almost every possible debug that could slow it down.
JRCU (Improves smoothness and responsiveness)
Optimized ARM AES and SHA1 Routines


I/O and Filesystem
Cleancache Enabled
CIFS Enabled
IO SCHEDULERS: SIO,VR,ROW,CFQ.
Some I/O Related patches.
NOATIME and NODIRATIME mounts set as default.
Fsync Toggle (Ezekeel)

Network
Proportional Rate Reduction in TCP - By Google
TUN/TAP Enabled
Support to change WiFi Power Management Policy to PM_FAST (Read FAQ)
Vpnclient support (Module)
Added more TCP Congestion Avoidance Algorithms: Westwood, Veno, Illinios, Vegas. Cubic(default). [ Choose which gives you the best speed! ]

Linux Memory Management
SLUB Memory Allocator (Better than the SLUB -> Default)
Tweaked all VM parameters for best performance
Upstream Linux memory management patches merged.

RAMDISK
No Compression for RAMDISK (++boot speed)
XZ Compressed Kernels.
Auto-Root Feature
Support to run init.d scripts on boot
Auto /efs backup (Needs testing)

CPU
Governers: Interactive,Conservative,Performance,Hotplug,Pegas usQ
Performance Governer is now core-aware, both cores are turned on for max performance (AndreiLux)
Interactive Governer synced with Android 3.4 Kernel.
Touch to boost CPU (Refer to FAQ!)

Installazione

• Scaricare il kernel
• Flashare il file zip da recovery modificata (twrp o cwm)
• Oppure scompattare il file zip ed estrarre il file .md5 ed inserirlo nella SD card
• Scaricare l'App Universal Kernel Flash
• Aprire l'app, selezionare select kernel, aprite con un gestore file che abbia i permessi di root, e cliccare sul kernel.
• Dopo la conclusione del flash andare in recovery mode e fare un wipe cache e dalvik cache, tornare indietro e fare reboot system now!

CONSIGLIATO FARE UN BACKUP DEL PROPRIO KERNEL IN MODO DA POTERLO RIPRISTINARE NEL MOMENTO IN CUI VI SIANO DEI PROBLEMI.


Per il Backup:

• Scaricare l'app Android Emulatore
• Digitare la seguente stringa scritta in rosso: $ su
  successivamente: dd if=/dev/block/mmcblk0p15 of=/sdcard/boot.bin
  dopo: reboot

Per il Ripristino del kernel Stock:

• Digitare la seguente stringa scritta in rosso: $ su
  successivamente: dd if=/sdcard/boot.bin of=/dev/block/mmcblk0p15
  dopo: reboot

NE IO NE TUTTOANDROID SAREMO RESPONSABILI DI EVENTUALI PROBLEMI ARRECATI AL VOSTRO DEVICE.​
