Governors and scheduler of your choice

Hi there.
I was wondering which governors and IO scheduler combinations are you using, or what would recomend for others . Im talking about ICS based roms. In order to try and help ppl i think that the combinations are suppose to be in this order:
1. Best battery life
2. Casual/daily (no much gaming, few calls, bit of data and wifi use)
3. Performance for gaming and such but still keep in mind about battery.
I found out that hellmanor kernel set with lionheart and cfq, gives me the best battery.
Didn't try anything else coz i need a ever lasting battery life.
Thanks for your participation

That depends on many factors. The usage... How many apps in background...

Dcop, what combination are you using?

I have IZS with kernel 0.4. I don't have many governors, but I'm using Lionheart with ROW as IO Scheduler.

Governors and scheduler
Hello this is my first post and i wanted to take this opportunity to introduce myself. I am from Spain and don`t speak english very well. It is a pleasure to participate in this wonderful forum.
I have Jelly Bean Mackay 2.7.2 and now i´m using Lionheart with Row as IO Scheduler. Before I was using Interactive with Row but the battery life was very little.
Greetings.

I'm use to the stock firmware with IZS kernel.
Governors - interactive,
scheduler - row. Very good balance.

Although it is a different device, here are some benchmarks:
CPU Governors and I/O Schedulers
Summary of the Results
SmartassV2 won the governor benchmarks, and also performed well in the battery drain benchmarks.
The best I/O scheduler to combine with this is noop.

You can't rely on names. You must also remember that while most kernels have same governors, they are tuned in a different way.
So let's say interactive on one kernel will perform different with another kernel. Best way is to know how it was tuned and the user experience.
Like 2 same cars, same engine but with different tuning. Know how it was tuned then drive it.
Here's a reference http://forum.xda-developers.com/showthread.php?t=1369817

Two days with Lionheart/row and battery consumption is very high. I'm going to try again with interactive/row to see if it improves the consumption of the battery the Mackay Rom (ver. 2.7.2).
Regards

I have V30C stock rom with Adagio 0.1a kernel,
I'm using intellidemand governors with vr as IO Scheduler. Battery life was very good.

I'm running the Marvel 11 (N00by) kernel and I've had good luck with setting the governor to "Performance" and the scheduler to "cfq".
Can't say that this is absolutely the best, but my battery life literally doubled from 9-22 hours to 22-48 hours. I get plenty of "Deep Sleep" mode.
I read an interesting tidbit on:
http://forum.xda-developers.com/showthread.php?p=26329039
I thought the most relevant thing concerning the Performance governor was:
"there is growing evidence to suggest that running a phone at its maximum frequency at all times will allow a faster race-to-idle. Race-to-idle is the process by which a phone completes a given task, such as syncing email, and returns the CPU to the extremely efficient low-power state."

I tried the last 3 days with performance and cfq, not the best, but it seems better than others, i guess there is something in that.

Currently on Mackay 2.7.6 and running the default interactive gov. with ROW I/O scheduler. Installed this ROM less than 24 hours ago. With moderate to heavy use with wifi on and off, battery is now at 63%.
Will have to try this for a week or so with regular charging cycles before I can draw any conclusions.
As someone else mentioned, the governors and schedulers for different kernels and ROM's probably can't be directly compared. However, it is interesting to compare to other people who are running the same ROMs and kernels and see what results they found.

Mi favourites are smartassv2 , ondemandx and sio and vr

I've updated the kgsl drivers and I believe there is an improvement there without having clocks

So this will work on any Sense rom running Android 4.3? Just want to clarify it was not a typo

It was confirmed by a tester to work on Sprint for android 4.3. Therefore it should work on Sense 5/5.5 as long as its 4.3.
Let me know if you guys have issues...I have the Verizon variant...so a little difficult for me to test.

So if we find issues can we pull a logcat? I've never reported issues with a kernel, so I was wondering if they would be any help

Am I seeing things? I had to do a double take

Did you set to apply kernel settings on reboot? The box is not checked by default.
This kernel works in BSC Tranquil 4.3 Sense 5.0 as well. Once the kernel is flashed, it activates the s2w/s2s and logo menu choices in kernel options settings in BadSeed Tweaks. Double tap2wake works with no setting required. For CPU clocking, it looks like Trickster Mod will still have to be used. But TM has s2w/s2s options there as well, so not sure which mod will rule, or if both mods will have to be set the same.

Yeah I checked apply kernel settings on reboot, still the frequency doesn't stick

Nobody is trying to say you did anything wrong, just trying to make sure you covered everything. What rom ate you trying this on? Maybe you have an init.d script in system/etc/init.d folder causing the problems. I've also been around since the samsung intercept and og evo 4G, so I feel ya...

I flashed the hotplug zip and was able to OC to 2.4 Ghz. I haven't tried anything else yet.

Okay wanted to ask this before I flashed but actually saw your source before this was posted and was really hoping to see this kernel soon, so I couldn't wait. But question on my mind and not sure if you will know the answer yet. Since it is based off of Liquids kernel, is there a possibility this could trigger the encryption bug? Super excited to see what this kernel can do and thanks for putting it all together.

Kernel tweaker can modify cpuquiet governors which trickster can't. Nothing can change msm hotplug settings unfortunately. I would try one of those two apps and see which you like better.

Surprisingly, no. I had assumed it would, but I guess flar is still working on that. I could make you a build with it though (might be at the cost of dt2w and s2w). If I can though, I'll try to add it to his wake gesture code so we have all three.

Dbl tap to wake is easy but agreed a soft sleep will be nice. I'm getting by with Slimkat's sleep toggle but the nav sweep is a nice touch. Thanks so much for giving it a go if you do!

Sounds like this will be a good one to try. For some of those asking about S2S, what launchers are you using? I was waiting for it, and finally decided ( I'm using Inspire Launcher, of course this will work with Nova, too) to assign a double tap on the display to sleep it as well.

Woot woot!

Works well thanks.

So not sure if this is the way it is, but after flashing hotplug. Two cores and it is random which two not always the same two are locked at max speed. They never go down to 300mhz or anything slower. They just get stuck at max speed. I can change the max speed and they change with that speed but they are always whatever speed I set it to. Is this the want the hotplug driver is setup?

Elix-r, decrypted, latest supersu, and elementalx ver 0.7 for kernel. Super smooth and fast

LS or Validus ( I switch back and forth until this bug gets fixed. )
Lean Kernel v1.1 UCOC (my favorite so far)

I honestly don't know what all the tweaks are. I only use that combination since it is said to be stable. I may just switch back to stock.
