اين كرنل رو ميشه بعنوان يكي از معروفترين كرنلهاي xda معرفي كرد ،
اوركلاك كردن ، آندرولت كردن ، پشتيباني از init.d، پشتيباني از CIFS و .... جزئي از قابليتهاي بيشمار اين كرنل هستند.
Features
کد:HighlightsPower Saving Features:
- Exynos-Abuse Secured (Thanks to AndreiLux for the original low level patch & Samsung for the Official Fix)
- SDS patch included
- Ramfs from Stock Kernel + Busybox and its various functions in /sbin
- Versions up to Rev1.00 were Based on Samsung Galaxy Note 2 N7100 Source Drop Release 1; Rev1.01 and up are based on N8000 Sources
- Included patches for performance, stability and battery life
- Init.d support
- SetCPU, ROM Toolbox and Voltage Control Support
- CPU Overclocking and Undervolting Support
- No GPU Overclocking and Undervolting
- Enable or Disable File Syncing (fsync disabled by default as I've tweaked the system for optimum latency designed for Flash Storage)
- CFS Autogroup by Mike Galbraith Enabled
- CPU Topology and Sched_MC enabled
- AFTR and LPA enabled
- A lot of tunables via sysfs included (Use ROM Toolbox or similar Utility to easily change it)
- Git Implementation of SHA-1 for 12% faster boot time
- CPU set at 1.6Ghz at Boot for faster boot time (Thanks to Imoseyon)
- LZO compressed kernel using optimized values for the size of the kernel for faster boot time
- CIFS Support (cifs.ko located in /lib/modules) | Tweaked Ext4 Filesystem (Patches + Mount Options + Tweaked IO Schedulers leaning towards latency for Flash Storage)
- sio | zen | noop | deadline (tweaked for better latency and balanced throughput for Mobile NAND based devices)
- Tweaked the mount options for Ext4 to adapt to the current focus on latency
- pegasusq | conservative CPU Governors (Patched conservative to support load based hotplugging)
- WiFi Multicast Blocked (Thanks to Entropy512)
- Using Toolchain 4.7.3 from Linaro+ compiler optimizations specific for that version (Thanks Linaro)
Boot Time Features:
- AFTR + LPA enabled
- sched_mc enabled (set at 2 by default)
- ARM CPU Topology enabled
- No HZ enabled
CPU Features
- Used git Implem of SHA-1 for 12% Boot time improvement
- Added [PATCH] arm: remove "optimized" SHA1 routines by Linus Torvalds
- Added [PATCH] arm: remove stale export of 'sha_transform' Linus Torvalds
- Set Clockspeed at 1.6Ghz 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)
Filesystem Features (Currently Supported)
- Supports CPU Overclocking and Undervolting (Thanks to AndreiLux)
- No GPU Overclocking or Undervolting
- pegasusq | conservative CPU Governors pegasusq set as default
I/O Schedulers
- ExFat (Using Proprietary Samsung Modules)
- Fat32
- Ext2/3/4
- CIFS (cifs.ko is in /lib/modules)
- Ext2Int for N7100 (Thanks to mattiadj for idea and base script that I used to get it fully working on N7100 and RedPill) (ExFAT and FAT32 only)
Memory Features
- SIO (2012 0.2 version) (tweaked for Flash) Set as Default
- deadline (tweaked for Flash)
- zen (Thanks to bbedward)
- noop
- Tweaked values in deadline and SIO I/O scheduler to give better than average throughput while attemting to improve latency (if not more aggressive). Based on our initial (indicative, not conclusive... yet) testing, having these in line with the vm dirty, expire, writeback values + ext4 mount options to "schedule" write outs as fast as the system can handle it works quite well to balance throughput with latency expected in a mobile device. We took the big picture view and tested our tweaks instead of copy pasting random "known" good values and challenged some assumptions even we had at the start. The result is a mobile device tuned for average throughput and balanced battery life with good latency (not the lowest latency out there, but given the benefits of better I/O throughput and potential battery savings + extending the lifetime of NAND Based storage I think it was a compromise worth taking) I could have tweaked it for extremely great throughput and battery savings but that wouldn't be fun to use. I hate micro-lags myself.

Display Features
- Custom minfree values tweaked for 2GB RAM
- Tweaked vm values in sysctl that's optimized for latency
- Stock mdnie values for more vivid details on the current generation of AMOLED Displays
