    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
    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.


    -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.

    Superbad -
    A "superbad" super smooth rendition of a highly optimized "smartass" governor!

    Darkside -
    A "slightly more agressive smart" optimized governor!

What else-----

  • -SLQB - (SLAB allocator with Queue)-(both)
    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).

    - Added Cleancache
    - Supports ext 2,3
    - Updated zRam
    - Lzo compression/decompression speed has doubled on average.
    - Init.d support
    - Fudgeswap
    - And much more :D
    - O/C and stable upto 2ghz, although I do not recommend O/C to 2ghz for long periods of time, do so at your own risk.

    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

9/ Vendor Options
- Fix for Anzu and Hallon Vendor problem

  • - Mount

Ok re-uploaded see how this one goes

First, thanks for your work,

but kernel seems not to boot?

(Tried it 2 times, md5 matches.)

Thanks to 8f86TcLjmt Kernel link fixed and now booting


Kernel now boots and wifi works Thanks @ Mr.Tapa for testing it and letting me knw :)

Thanks that you did it. You can try to enable V-Sync in kernel and see if uers are happy. I did it on sirkays kernel and some games become fc. But it depends on many things. So make a version with Vsync enabled.(VERTICAL Sync. Thats teh main thing that Project butter uses among with egl confings and gpu cpy hardware syncs)

    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.
