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.
Dual-booting
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 arter97-multi-boot.zip. 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.
Knock-On
arter97 kernel offers full Touch Wake functionality(by Ezekeel & Yank555.lu) 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.
Compiler
arter97 kernel uses the latest Linaro-toolchain. 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.
File-system
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.
f2fs
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.
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
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
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
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
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.

do some research if you have any concerns about features included in this kernel

you point the finger at me for messing up your device, I will laugh at you. Hard. A lot.

/* FAQ */
I get 'status7' error while installing!
Your recovery is out-dated. Go and install a newer one.
Any recommended kernel settings?
The defaults are the most recommended settings. Try and use the default settings for several days before tweaking it yourself.
No GPU clock controls?
No. I personally don't like exposing GPU clock controls to users. I have no plans of adding these controls to my kernels.
I'm experiencing data-losses, device shutdown while downloading torrents!
Please turn off 'Dynamic Fsync' from aTweaks. Note that this may make your device slower.
Screen mode settings are not working!
mDNIe settings is moved to aTweaks. Please use the settings from there.
My screen color is inverted!
Tap the home-button 4 times. It's a kernel feature, please read the entire post.
The boot animation is laggy after installing this kernel!
The root cause is unknown for now, but it is normal and doesn't affects anything else.
Personal Hotspot is not working after switching to another kernel!
It's due to hostapd binary change. Go and re-flash your ROM.
