Built with Linaro

This kernel can be used on any JB CM BASED JB 4.1 or 4.2


#include <std_disclaimer.h>
* Your warranty is now void.. LOL I guess you knew it already.
* I am not responsible for bricked devices, dead SD cards,
* thermonuclear war, you getting dumped or you getting fired because your phone 
* bootloops and alarm does not go off. Please do some research if you have any  
* concerns about features included in my kernel before using it! YOU and only 
* YOU are choosing to make these modifications.

You have a question post it in the thread,
Instead of Pm'ing me, as other users may
experience you problems

What Works --
Wifi - (flash modules)
Everything Else that works on FXP

What doesn't work --
Anything that doesn't work on FXP

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

Added Governors --


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!

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.

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).
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 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."

- BFQ - Budget Fair Queueing IO-Scheduler-

From Creators

* Copyright (C) 2008 Fabio Checconi
* Paolo Valente
* Licensed under the GPL-2 as detailed in the accompanying COPYING.BFQ file.
* BFQ is a proportional share disk scheduling algorithm based on the
* slice-by-slice service scheme of CFQ. But BFQ assigns budgets,
* measured in number of sectors, to tasks instead of time slices.
* The disk is not granted to the active task for a given time slice,
* but until it has exahusted its assigned budget. This change from
* the time to the service domain allows BFQ to distribute the disk
* bandwidth among tasks as desired, without any distortion due to
* ZBR, workload fluctuations or other factors. BFQ uses an ad hoc
* internal scheduler, called B-WF2Q+, to schedule tasks according to
* their budgets. Thanks to this accurate scheduler, BFQ can afford
* to assign high budgets to disk-bound non-seeky tasks (to boost the
* throughput), and yet guarantee low latencies to interactive and
* soft real-time applications.

    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.

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.


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.

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.

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.

Mirrors -- all LuPuS Kernels can be found here

Wifi is built in to kernels ramdisk NO MODULES NEEDED


- zRam is not enabled by default unless on CM10 ROM, for AOKP to enable it flash the 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

or alternatively

cat /proc/swaps

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

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.
