Included in Kernel-


-24 governors (ondemand default)
-6 io-schedulers (sio default)
-O/C up to 2ghz although not recommended
-fudgeswap
-slqb memory allocator
- Increased zram disk size
- Increased zram to 30%
- Changed LZO --- Benchmarks show compression and decompression times performance increased by double
- Linaro optimizations from my ics-beta

Lulzactive - Thanks to Tegrak
Based on Interactive and Smartass. When workload is greater than or equal to 60%, the governor scales up
CPU to next higher step. When workload is less than 60%, governor scales down CPU to next lower step.
When screen is off, frequency is locked to global scaling minimum frequency

Virtuous (recommended) change with nothrills cpu or similar app
Virtuous is a modded smartassV2 which gives even more battery time then smartassV2

Intellidemand - Thanks to faux123
This is an intelligent ondemand that enters browsing mode to limit max frequency when GPU is idling,
and (exits browsing mode) behaves like ondemand when GPU is busy; to deliver performance for gaming and such.
Intellidemand does not jump to highest frequency when screen is off.

Lazy - Thanks to Ezekeel
The Idea here is to eliminate any instabilities caused by fast frequency switching by ondemand.
Lazy governor polls more often than ondemand, but changes frequency only after completing min_time_state
on a step overriding sampling interval.
Lazy also has a screenoff_maxfreq parameter which when enabled will cause the governor to always
select the maximum frequency while the screen is off.


-[COLOR="Green"][B]Ondemandx
Basically an ondemand with suspend/wake profiles. This governor is supposed to be a battery friendly ondemand. When screen is off, max frequency is capped at 500 mhz. Even though ondemand is the default governor in many kernel and is considered safe/stable, the support for ondemand/ondemandX depends on CPU capability to do fast frequency switching which are very low latency frequency transitions. I have read somewhere that the performance of ondemand/ondemandx were significantly varying for different i/o schedulers. This is not true for most of the other governors. I personally feel ondemand/ondemandx goes best with SIO I/O scheduler.

-Lionheart:
Is a conservative-based governor. The tunables (such as the thresholds and sampling rate) were changed so the governor behaves more like the performance one, at the cost of battery as the scaling is very aggressive.

To 'experience' Lionheart using conservative, try these tweaks:
sampling_rate:10000 or 20000 or 50000, whichever you feel is safer. (transition latency of the CPU is something below 10ms/10,000uS hence using 10,000 might not be safe).
up_threshold:60
down_threshold:30
freq_step:5
Lionheart goes well with deadline i/o scheduler. When it comes to smoothness (not considering battery drain), a tuned conservative delivers more as compared to a tuned ondemand.

BadAss Governor ?:
Badass removes all of this "fast peaking" to the max frequency. Badass will also take the gpu load into consideration. If the gpu is moderately busy it will bypass the above check and clock the cpu with 1024Mhz. If the gpu is crushed under load, badass will lift the restrictions to the cpu.

Overclocked to 2ghz--- don't think its to stable though---
Please give feedback wether its stable for you or not if you overclock


FudgeSwap
-Helps improve multi-tasking in low memory situations forcing apps to swap.(already in DooM's sources)

SLQB - (SLAB allocator with Queue)-
This memory allocator is designed for small number of CPUs system (such as desktop or smart phone devices). This allocator is design to be simple and it is optimized for using order-0 pages as much as possible (order-0 pages are the simplest therefore quickest type of memory in a Linux system to allocate).

    VM tweaks (explained below)

VM Tweaks


dirty ratio and dirty background ratio 1 & 2
This controls how often the kernel writes data to "disk" (in our case the internal microSD system card, not the removable microSD card). When your apps write data to disk, Linux actually doesn't write the data out to the disk right away, it actually writes the stuff to system memory and the kernel handles when and how the data is actually going to be flushed to the disk. These values represent a percentage, the higher the percentage, the longer it waits to flush, the lower the percentage, the more often flushes will occur. Now remember, we are dealing with solid state storage, not the traditional disk platter and spindle. So we are actually able to delay flushes a little longer with solid state versus a traditional hard drive disk.


dirty_expire_centisecs
How old "dirty" data should be before the kernel considers it old enough to be written to disk. It is expressed in 100ths of a second.

dirty_writeback_centisecs

This is the interval of when the writeback daemons periodically wake up and write "old" data out to disk. It is expressed in 100ths of a second.

min free kbytes
This is used to force the Linux VM to keep a minimum number of kilobytes free. The VM uses this number to compute a pages_min value for each lowmem zone in the system. Each lowmem zone gets a number of reserved free pages based proportionally on its size. Default is 2048kb.

overcommit_memory
This controls overcommit of system memory, possibly allowing processes to allocate (but not use) more memory than is actually available.

0 - Heuristic overcommit handling. Obvious overcommits of address space are refused. Used for a typical system. It ensures a seriously wild allocation fails while allowing overcommit to reduce swap usage. root is allowed to allocate slighly more memory in this mode. This is the default.
1 - Always overcommit. Appropriate for some scientific applications.
2 - Don't overcommit. The total address space commit for the system is not permitted to exceed swap plus a configurable percentage (default is 50) of physical RAM. Depending on the percentage you use, in most situations this means a process will not be killed while attempting to use already-allocated memory but will receive errors on memory allocation as appropriate.

Swappiness
A property for the Linux kernel that changes the balance between swapping out runtime memory, as opposed to dropping pages from the system page cache. Swappiness can be set to values between 0 and 100 inclusive. A low value means the kernel will try to avoid swapping as much as possible where a higher value instead will make the kernel aggressively try to use swap space.

VFS Cache Pressure
File system cache (dentry/inode) is really more important than the block cache above in dirty ratio and dirty background ratio, so we really want the kernel to use up much more of the RAM for file system cache, this will increas the performance of the system without sacrificing performance at the application level. The default value is 100, as a percentage, and what you want to do is lower the value to tell the kernel to favor the file system cache and not drop them aggressively.


8/ Enable / Disable Quick Key Reset
- Reboot device quickly by Holding HOME and POWER Key (Disabled by default)
  • - Enable
    - Disable

Downloads

If you need root for STOCK ROM
Code:
Root : ( Flashable via recovery )
* SuperSU : Download
* Superuser : Download

If coming from version before v7, you need to wipe all partitions..

======================== 720p Recording ========================

If your MD5's don't match then re-download before saying it doesnt work


*******No need to flash wifi modules they are only in attachments as a backup*******

Important

Coming from a kernel with STOCK partitions??
Via fastboot enter the commands:

Code:
fastboot erase userdata
fastboot erase system
You must wipe userdata and system if coming from a STOCK partirion kernel, Otherwise u will be stuck in a loop

.


What is CIFS???
  • Server Message Block (SMB) or Common Internet File System (CIFS) are normally used to provide shared access to files on a network, mostly involving computers running MS Windows.

    It allows you to conveniently mount/unmount your network accessible file resources and access the files transparently via your favourite Android app (playing music / videos, accessing documents etc.) Settings are stored on your SD card with permissions to write also to your SD card.


Now download CifsManager or similar app and configure it

Zram is not enabled by default- to enable it flash the wedgess-NEW-Zram-Enabler.zip below
If for whatever reason you want to disable it after you have flashed the .zip, just go to ect/init.d and delete 00zram

Wedgess thanks for making a gb kernel but can you add CDMA support for those of us on R800x on your spare time? If you dont mind I will fill you in about my xperia play.

This is a thread from doomlord that has a working CDMA kernel which is based on version 2.3.3 gb. Doomlord was able to create a 2.3.4 kernel for us R800x users but camera functionality doesn't work at all. (I was hoping for the thread to be revived but it seems development has been put to a stop) So were stuck on doomlord gb 2.3.3. Currently I'm using kernel v1 from doomlord that has a working recovery and i am not using v2 posted in the thread below.

Since you don't have the device (that im aware of) I don't mind testing it if you wish
