First Working JB kernel for NEO-L
Hi, I have kernels for the PLAY and seen as slz.kiev helped me bring the great PACman ROM for Xperia PLAY, Which I then ported to your NEO-L. So I decided to create a more custom Kernel for use withmy PACman ROM for NEO-L. There is more to be added
but for first release you get 25 governors 6 io-schedulers, SLQB memory allocator, a few changes to make
android smoother. It is also built with linaro 4.6 toolchains. And wifi signal and lock on should be increased
This kernel can be used on any JB CM BASED roms as it has its own set of Wifi Modules
#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. */ #ifdef You have a question post it in the thread, Instead of Pm'ing me, as other users may experience you problems #endif

- + the 5or6 that are there with FXP
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 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.
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 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.
A "superbad" super smooth rendition of a highly optimized "smartass" governor!
A "slightly more agressive smart" optimized governor!
- -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
- Updated zRam
- Lzo compression/decompression speed doubled on average
