  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!
  
  Intellidemand2 - Thanks to faux123 and CosmicDan for mods
  Uses d_bus ramping, quick and smooth and performance based, do not complain about battery drain on this
  governor but it will make everything feel more like project butter

What else-----

• -SLQB - (SLAB allocator with Queue)
  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).
  
  - Alot of changes to code to try improve smoothness ect
  - Wifi signal lock on should now be quicker / stronger then before

--When LEDS change green, pink then blue press volume down to enter CWM Recovery

  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.

Wow...nice one! Really responsive! Just wanted to point out that in addition to all the features listed in the OP, that you can undervolt
with this kernel....didn't see it as a feature in the OP...

Thanks!

very smooth, but has a problem the wifi seems works not stablely, sometimes cause reboot and sometimes cannot been disconnected.

Did you reboot? I have no problem with wifi. Only at first boot I had this problems.

testing...
(thx for your effort sofar :good

1st impression: lower scores on Antatu than with standard PAC-kernel.

i'd like to have a better battery life, so now testing "virtuous/sio, 806/134".
or are there better suggestions?
(like to keep a snappy Ray )

 

[Wechy77]

"Custom voltage control supported" not working. The PAC romcontrol says: not supported by your kernel

I don't think that part of RC has been activated....it also doesn't work with the kernel from champilnswimmsr's aokp build. I am using incredicontrol from the play store...but a lot of other apps will let you change the volts.

is there a list of recommended (or safe) voltage settings for the Ray?

 

[wedgess]

Yes i know in rom control it still says not supported not sure why but u can always use SetXperia app from playstore to change it

And poster who asked about safe settings. Try down step -25mv at a time and see what is stable for you. If u get reboots then its obviously not stable.

Or else safest way if your wortied then dont undervolt at all. What maybe stable for someone might not be stable for you

I tryed thi kernel for my CM10 rom. And it seems buggy. Antutu points is lower than on stock kernel, and the perfomance is bad too, including games and UI.

lol ok first off this is not stock kernel so you can't compare it to STOCK,Ssecondly i'm not sure what governors, io scheds and frequencies you are using. People who have tested have reported it being smooth and performance being greater not worse. Also I obviously use my own kernels on my own device and my experience is the complete opposite of yours. You sure it not 'your' CM10 rom. Buggy!! how? please do elaborate.

Anyone else confirm what the above pster has said ??

 

[[GER]Roxxor]

Using it now for some hours with Virtous and SIO and looks very promising. Speed of ROM is for me the same and I dont play games. But Battery seems to be great! I left the screen off a lot and have like 95% deep sleep, so pretty well battery ;D I use FXP142.
EDIT: just tested the game "granny smith'. Runs good! But I didnt test with another kernel.

Ye virtuous is supposed to be more battery friendly then smartassv2
Intellidemand2 would be best performanced based but not the best on battery.

[superwoosh]

Thanks for the great kernel, really liking the Superbad governor.

 

[dreezz]

I left my ray on during the night, to see what the battery would do...
(i mean screen off, but wifi+3g on)

from 100 to 74% in 9 hours.
8:40 deep sleep (94%)

806/134 virtuous/sio

I cannot compare btw, usually i charge at nighttime, but usage seems quite high?
was hoping for about 90% battery left or something, but like i said, not tested with other kernels.

 

[justmpm]

I think I caught a "wifi" bug. Yesterday the wifi cut out and wouldn't turn back on...after rebooting everything was fine for a few hours and then wifi stopped working. I am not sure if it is really wifi or something else, because if I go into settings I see that wifi is on, I can turn it off but it won't turn back on...if I leave settings and pull down the status bar it show wifi as "on"...when I go back into settings it shows wifi as "on"...and no networks are shown that can be connected. You can do this over and over and every time you reenter settings it says wifi is on. I think it also causes a wakelock from wifestatemanager.

I went into recovery and formatted system and reinstalled PACman v15...a few hours later the problem returned. I flashed in a different kernel and it seemed OK....now I have your kernel on ChampionSwimmer's AOKP ROM and I am waiting to see if the bug returns.

I am not sure if there is something specific I do that activates the bug, so I don't have a logcat of it happening. I attached a logcat of me trying to turn on and off wifi in settings. I also attached the battery stats report from Better Battery Stats in case the wakelock is informative....
