Whats Included in kernel ------------

  • 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.

    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

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

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

    -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.

    -Virtuous
    Virtuous is a modded smartassV2 which gives even more battery time then smartassV2:)

    Added Io-scheduler --
    VR io-scheduler - Unlike other schedulers, synchronous and asynchronous requests are not treated separately,
    instead a deadline is imposed for fairness. The next request to be served is based on it's distance from last request.

    - SIO - Simple IO-Scheduler-
    SIO is the default scheduler in this kernel. It is widely-regarded as the best all-round performing IO scheduler for android. It is low on CPU usage and optimized for flash-based storage. From the creator - "Based on Noop, Deadline and V(R) IO schedulers. This algorithm does not do any kind of sorting, as it is aimed for aleatory access devices, but it does some basic merging. We try to keep minimum overhead to achieve low latencies. Asynchronous and synchronous requests are not treated separately, but we rely on deadlines to ensure fairness."

    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.

Wifi is built in to kernels ramdisk NO MODULES NEEDED


DO NOT MIRROR MY DOWNLOADS


- zRam is not enabled by default unless on CM10 ROM, for AOKP to enable it flash the wedgess-zram-enabler.zip in CWM
- If for whatever reason you want to disable Zram after you have flashed the .zip, just go to ect/init.d and delete 00zram



People will ask so i'll just post it here---------to check if zRam is enabled go to terminal emulator or similar and type

Code:
free

or alternatively

Code:
cat /proc/swaps


Please Click Thanks :good:

A lupus Kernel for CM10 Arc???. I'm about to donate :good:

Just as an advice... If you develop an arc kernel for GingerBread (even CM 7.2), I'll donate again.

So much thanks for you.

:highfive:

this kernel is for both arc wnd arc s :) thank you man tgat would be great ;) as for cm7 u might just motivate me. but rite now i have no intention.


to poster above me i have made stock gb for the play as i own one not pro only ics for pro and arc/s :rolleyes:

i flashed the modules.. wifi not working
lt15i , cm10

EDIT: i reflashed modules/ fix and fixed permitions, wifi is working fine for now :)

EDIT2: after just few seconds of using, wifi has stopped working, and also system settings FC's a lot..

flashing back fxp's kernel :(

    - zRam is not enabled by default unless on CM10 ROM, for AOKP to enable it flash the wedgess-zram-enabler.zip in CWM
    - If for whatever reason you want to disable Zram after you have flashed the .zip, just go to ect/init.d and delete 00zram



    People will ask so i'll just post it here---------to check if zRam is enabled go to terminal emulator or similar and type

    Code:
    free

    or alternatively

    Code:
    cat /proc/swaps


    Please Click Thanks :good:

      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.
