[Xperia Arc Android Development] wedgess:
LuPuS Kernel Stock

Hi I have kernels for the PLAY and one for the PRO, ARC/S users where pm'img me to make my one for the PRO compatible

with the ARC/S. Unfortunately they never got back to me about testing, But no worries as

besttt

said he would test

for me and thanks to his extensive testing it was able to boot and apparently is super smooth :p well i'll release so you can all test

it out for your selves :good:

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.

Show your support for the kernel and my work by putting this in your signature, its only a quick one I done up with my limited time :(

For v2 i've started from scratch from Sony's xx.587 sources, I know everything might not be added and some things may need to be fixed

so anything that needs to be fixed or you would like to be added leave a suggestion (not an order) in the thread. Everything mentioned above has been added.
