Nexus S Scheduler/Govenor Matr1x

Hey Guys,
I have a Nexus S running the Matr1x 17.5 kernel. There are a ton of Scheduler and Governor choices. I was wondering what combination of the two will get the best battery life?
Thanks.

hi. i'm using smartassV2 governor, cfq scheduler and deep idle on - everuthing works great and i get over a day and a half.
cheers
hit thanks if u wan't.

There is a thread testing governors and scheduler combinations somewhere on here and from what I remember the best combinations were smartassv2 with noop if you play alot of music etc with screen off and ondemand with deadline if you have the screen on alot.

There are two threads to look into.

But it really depends how you use your phone and every phone behaves a little differently and it also comes down to your Rom+Kernel combo.
Personally I use Matr1x cfs 17.5 + CNA 1.4 - Ondemand/deadline 200/1000 for screen on and
lulzactive with custom settings 200/800 w/ deep idle and noop for screen off.
You just have to play around a bit and see what suits you.
Good luck!

Thanks, how do you set it to change on screen off? Like you say it changes to lulzactive when screen off....how do you do that? Thanks again

msm-dcvs governor battery life

hi guys,
I recently switched to msm-dcvs governor, and I'm noticing a great improvement in battery life! It's included in stock kernel, so give it a try

In my kernel has a smartmax. IMHO, it - even better.

Don't smartmax give a pretty bad performance in games?

For energy conservation, I recommend using Smartmax. For other - ondemand.

[Q] Governors & I/O schedulers?

Please forgive me for asking, if this has already been answered. Question for the Devs... Will any future releases (kernel only, or ROM) include a wider selection of governors and i/o schedulers, or is this device limited to the ones already available for some reason?
Coming over from HTC Glacier and Doubleshot, there were more choices than I knew what to do with. This is my first Samsung device.
Not that I'm complaining, I've found a combination that works good for me. I just wanted to know.
By the way - you guys are doing some great work over here. I'm loving this phone. Thanks!

This would be done on the kernel level and it is certainly possible to add more options but doing so can make things less stable.
If there is something you think may work better you could ask a dev if implementing has been tried and what the result is otherwise the main kernel source is available on github and there are many guides to build yourself and test

I'm sure the devs have sound reasoning behind their choices. I was just curious to find out if it was something device specific, as opposed to dev preference. I don't know that I would go so far, as to tamper with the kernel source myself. I don't have those skills yet. I may look into that in the future. I'm always willing to learn.

Hit the app store and grab CPU Tuner, you might find it's got what you need.

Thanks, I'll check that one out but I believe that apps like that will only allow you to select from the governors and schedulers that are available in the kernel itself - not implement one that isn't there. I'd like to try out intellidemand, or smartassV2 with this device.
Right now, I'm using the interactive governor & sio. Then using SetCPU with profiles for screen-off, screen-on, and charging. This is kind of giving me the results I wanted. Sort of gives me an interactiveX, I guess? SetCPU doesn't show me both cores, so I really don't know. Also have tried Kernel Tuner and Trickster with mixed results.

Just downloaded CPU Tuner. This appears to be a better alternative to the other ones I've tried. I can get what I want without trying to mess with the kernel. Gonna run the "Sophisticated" config + Performance profile for a while and see how it goes. Thanks! :good:

my roms have more freedom of the kernel with this...current governors in my builds are: conservative, ondemand, userspace, powersave, interactive, and performance. Current I/O schedulers are noop, deadline, row, cfq, and sio. i will be exapanding on this soon but sio and interactive or sio and ondemand have given the bast stability for me.

I've been running your Carbon ROM for a little while and I've been pretty pleased with it. I've settled on the interactive and sio combination but I wanted to have a little more control. Most of the time I just text and do a little web browsing, so I want to extend battery life. But I have access to a lot of wi-fi hotspots, so then I can plug in for some gaming or Netflix. It's nice to have the performance amped up then. I seemed to have good results with intellidemand and smartass variations on my other phones.
I appreciate your work, thanks!

your very welcome...as ive stated before i will be adding some more here soon. i have a couple of new rom builds im working on and an update to another...i definitely need to work on the kernel as ive done little patches here and there but nothing too big....think within the next few weeks ill do a big update to it and update all my roms with it

Perhaps you could release a flashable kernel for people on cm?

Errr What advantages are there from sio over the other i/o schedulers. That's the only addition between your list and what we are currently enabling.

Simple I/O (sio) scheduler aims to keep minimum overhead to achieve low latency to serve I/O requests. No priority quesues concepts, but only basic merging. Sio is a mix between noop & deadline. No reordering or sorting of requests.

I notice a difference in performance when I change governors but I can't say that I notice a difference at all, when changing i/o schedulers. My understanding is that certain combinations are supposed to work better together. I just remember that devs of certain mods I've used had a preference for sio o over the others. Not sure why, but it worked, so I've stuck with it...

Hotplug optimizations

Hello everyone!
Dan asked for ideas for lspeed.
While govtuner is great, maybe hotplugging can also be more optimized.
Govtuner optimizes zzmoove inbuild hotplug but leaves every other hotplug untouched.
Dan wants to start optimization of hotplugging next month and asked me to open this thread to collect your current settings and values.
So if you are interested in optimization of hotplugging, please share your current setup in this thread.
You can post screenshots from KA or just list your available options for hotplug along with the tuneables.
This will be the starting point for the optimization next month.
Best regards
dr.zook

Here are my options for hotplug
@Paget96 Dan, if I have forgotten anything, please tell me

Thanks for saving my time, what i need. Soon when i grab some time I'll start with hotplug optimizations.
I can't give an ETA or something, but, expect it soon, till then, share your setups and hotplugs.
Thanks for support

I would like to report on Hotplug governor, but I have only HTC Desire S which has only single core. So I could not participate anyway. Thanks for you guys kind contribution. Thank you very much.

Blu-plug from blu_spark kernel
my Device is a Nexus 5

We can start filling up this thread again

Sony Xperia Z5 (SoC: Snapdragon 810)
Stock msm hotplug
Tunables path: /sys/devices/system/cpu/

Today I'll start with profiling hotplugs. I'll add three profiles battery, balanced, performance for next hotplugs:
- IntelliPlug
- Blu_Plug
- MSM Hotplug
- Mako hotplug
- AutoSMP
Device: Nokia X2

Althrough this is not probably the thread to ask it . Do you guys by chance use any hotplug which has a freq limit to turn on the cores? Since it seems most hotplugs turn on the cores when the highest freq hits and I'm not that happy about it.

Well blu_plug do it based on threshold.

Most of them do it based on threshold. Found some which do it based on freq buts it seems thats its a pain to port them. I asked some dev about what do they think of hotplug on newer device and it seems its useless now
