    Altre info:
    Based on stock SHV-E210S kernel source
    Samsung has put massive updates in their Android 4.4 kernel compared with Android 4.1 kernel. By being based on stock SHV-E210S kernel source, arter97 kernel is miles ahead of where other CyanogenMod-based kernels are slowly catching up behind.
    arter97 kernel implements simple yet seamless multi-boot solution that does not need a dedicated recovery. It's also faster, thanks to raw extracted method instead of slow loop mounted images.
    To start, enter recovery(CWM, PhilZ) and flash The ZIP files you flash afterwards will be stored in the 2nd-ROM slot(/data/arter97_secondrom) until you exit or restart recovery.
    Reboot back to 1st-ROM, and use newly installed 'aSwitch' to control 2nd-ROM. You cannot select between two ROMs on the initial start-up time.
    * 2nd-ROM's /system partition will be always mounted R/W due to its limitations.
    * Backup & restore will not work for 2nd-ROM. Don't try it unless you want your entire device screwed all over.
    * Do not select data wipe on 2nd-ROM installation! 1st-ROM data might be lost instead.

    Advanced mDNIe control
    arter97 kernel offers advanced mDNIe control by AndreiLux, leaving every single controls available for the screen in the palm of your hands.
    arter97 kernel offers full Touch Wake functionality(by Ezekeel & with additional 'Knock-On' feature. Within the desired timer you set, Touch Wake will only work by double-tapping.
    Touch Wake
    Touch Wake has been improved in arter97 kernel. Not only the implementation of 'Knock-On' feature, you can now set a seperate timer on charge, force to also work on physical button pressed.
    arter97 kernel uses the latest Linaro-toolchain 4.9.3. Linux kernel's compiler profiles has also been backported from Linux 3.16 for more compiler bug-fixes, performance improvements.
    Memory managements
    arter97 kernel is fully upstreamed to the latest Linux 3.0.101. This provides improved stability, performance and memory management. But many developers forget to properly match Samsung's CMA memory management to Linux 3.0.101. arter97 kernel is the only kernel properly upstreamed to Linux 3.0.101 with CMA, meaning better memory management than other kernels.
    If you're using Android 4.4 KitKat, ROM can work together with arter97 kernel which improves memory managements even further.
    Battery and access speed to /sdcard is also improved by utilizing Samsung's sdcardfs and ditching Google's fuse implementation. Users can disable sdcardfs allowing FolderMount to work properly.
    FAT32 latency is improved, and AIO(Asynchronous I/O) is backported from Linux 3.6 with latency improvements.
    arter97 kernel is the first Android kernel(since 2013/08) to feature full f2fs support with selective partitions preferences. If you manage to make a switch from ext4 to f2fs, theoratically, your device's flash storage can perform up-to 2x faster. arter97 kernel also continously backport the latest f2fs from Linux 3.19+. This f2fs will be even more faster, reliable than other Android kernels.
    PhilZ recovery dedicated for f2fs makes users easy to switch. Install kernel and recovery, wipe /data and /cache, that's it.
    CPU governors
    arter97 kernel offers you alot of governors to choose. Besides the stock governors, you can now choose between PegasusQ+, YankasusQ, LulzactiveQ, SmartAssV2, ZZmoove and Intelliactive. Default is PegasusQ.
    You can overclock to additional frequency, 1500MHz, 1600MHz, 1704MHz and 1800MHz. A special underclock frequency, 100MHz is also available. If you do not experience deadlocks with 100MHz, it's recommended to use 100MHz as it can improve battery.
    arter97 kernel features Intelli-plug by faux123 with smart switch. You can now use ondemand, intelliactive or other non-hotplug-implemented CPU governors with profile-selectable hotplug functionality.
    Intelli-plug is automatically disabled when lulzactiveq, pegasusq, pegasusqplus, performance, powersave, userspace, yankasusq or zzmoove governor is selected.
    Boeffla Sound Engine
    Boeffla Sound Engine is the only custom audio engine available in arter97 kernel. Go and download 'Boeffla Sound Control' from Google Play store.
    Android logger control
    Android logger, aka logcat can produce a lot of garbage datas even when you don't need them. You can explicitly disable Android logger completely, or make it clear itself when the screen goes off(which is the default).
    Mali graphics
    arter97 kernel uses the latest Mali driver available for Samsung's Exynos 4412 phones, r3p2. It also uses the latest Mali blobs from N7100 ROM, which is built more recently than GT-I9300 ROMs.
    Automatic kernel panic log dumper
    When you use a custom kernel, you may experience unexpected malfunctions like sudden reboots. You should dump the kernel log and report it to the developer to help, but it may be very tiring to manually dumping and sending it. To make your life easier, arter97 kernel automatically dumps kernel log when kernel panic happens, and stores it on /sdcard/arter97.
    Kernel-side Camera shutter sound control
    arter97 kernel can force and turn off the speaker while the rear camera is operating. Since this is a kernel-side implementation, it doesn't need any ROM side support. Control available from aTweaks.
    Powerboost is a function that dynamically boosts your device's performance when an external charger is connected. Since none of the power savings are needed while the device is charging, you can experience much more faster speed during that period.
    Boost-boot is a function that can reduce boot-up time up-to 20 seconds. It uses 'performance' CPU governor, 'no-op' I/O scheduler and 1024kB readahead when the device is booting.
    aTweaks is a live-kernel-controller dedicated for arter97 kernel based on STweaks. You can control almost every aspects that arter97 kernel offers. Installing BusyBox before using is recommended.
    aSwitch is a dual-boot settings for arter97 kernel. It can wipe 2nd-ROM's /system, /data and /cache. You can also set /sdcard sharing option within aSwitch.

    Source code:


    Non serve fare nessun wipe, funziona come il kernel justarchi preleva le info dal vecchio kernel. unico accorgimento se si decide cambiare kernel dopo che si e installato questo bisogna rimettere quello originale della rom.

    Usare recovery PHILZ oppure quella modificata da Arter97 qua
    Mettere il file nella sdcard e fare la installazione.

    Una guida letta su XDA da parte di justarchi, spiegava i vantaggi di usare il file system della sdcard in ext4 (per chi la vuole leggere qua) nel mio caso non sono riuscito a far funzionare la ext4, ma approfittando della sdcard vuota ho messo come file system f2fs
    Questo cambio lo potete fare tranquillamente dalla recovery.
