i heard/read about it in my SGS2's time... It was implemented by Gokhan in his kernel but later stripped out because of some problems. PegasusQ is said to be made to handle Quad-core like our One-X, and SGSIII is said to be using this governor by default... Will we be able to see this governor in future Kernel build? or its not compatible technically with Tegra-3 since its a 4+1 setup? Can someone with the knowing enlighten us?
it seems that no one is interested with this
The latest Siyah kernel for SGS2 actually uses pegasusq by default.

Murag wala gyud intresado.which is better for sgsII in terms of battery life?this governor or the hotplug?
I'm afraid I can't help with this, sorry, I do have a Question however.
I've seen people talking about Governors etc, is that something to do with the Chips in the Tegra 3?

A governor changes when the CPU changes frequency. More time spent at lower frequencies will, of course, mean better battery life - but lower performance. The trick is to find one you like.

It is missing a few governors I've seen (such as PegasusQ) but is fairly complete.

As far as I know, The only way to try other governor is to create a custom kernel, because the governor code is built inside the kernel code.
Hmmm... I was wondering about OnDemandX, but unfortunately the linked threads don't seem to be aware of it...

I think this is now the only major deficiency in our device, having different kernels, governors and schedulers. I have a friend with GS2(AT&T) and he uses Pegasus governor with deadline scheduler on Siya Kernel, absolutely unbelievable battery life!! Just an appeal to our great devs out there, we could use a bit if that

If you read the OP of the Team Kernelizer's thread it'll answer most of the questions.
1. over-clocking/under-clocking refers to adjusting the speeds which your processor is allowed perform at. Over-clocking means that you can set it as a higher speed and under clocking is that you can set it at a lower speed.
2. There are many different threads on what each of the govenors and schedulers do. In the OP of ktoonsez's kernel thread there are links which give pretty good explainations as to what each of them do.
3. Tweaking your kernel is going to be something that is pretty much dependent on your phone and finding the proper pairing for your phone of frequencies, govenor, and voltages for each individual frequency step.
4. The voltage settings are how much power the processor is allowed to pull while it's at each individual frequency step. These can be changed to optimize performance as well as increase battery life. undervolting too much though could result in issues with your phone.
All of this is very much trial and error.
In order to change any of the kernel settings, use the ktweaker app that was installed on your phone when you installed the Ktoonsez kernel. The app should be in your app drawer.

Thank you! I already know about the Ktweaker app as I've used it already because I followed the steps in the thread and tweaked my kernel already for the "good battery+performance" setting. Although not gonna lie, I did not know what I was tweaking lol. I do notice amazing battery life though... after those tweaks I got 60hrs with 3 1/2 hrs of on screen time (4200mAh extended battery). I just wanted to clarify what I was doing. Plus I always hear about over-clocking/under-clocking but I don't know what it is or how to do it.

Over/under clocking and under volting are explained/described pretty well in the OP of the team kernelizer's thread. That being said that sounds like some pretty great battery life.

Not as far as I know. I can't speak for the V500, but for the V510gpe, simply changing the governed and Io scheduler was enough to see dramatic improvements. A few other tweaks, and I was able to get an extremely fast interface while under clocking the CPU. Far better than the original.
Is there some reason you want it? Or just because? I understand "just because" too

I just ported Row to my kernel to see if there is a positive difference. The answer is . . maybe. The two react differently under different uses. I haven't messed with it more than 10 minutes yet so the jury is still out.
For those interested, the latest kernel sleekai5.3 for the gpe will be posted in a minute or five, with the addition of Row Io Scheduler, and swipe to sleep. See kernel thread for more details.
Hi guys,
I'm new to android and I just flash a cook rom with custom kernel to my phone.
I use Kernel Tweaker to set some variable to make it use less battery and smoothly but I see an option called Intelli-plug.
I google this and see it complete replacement for MP-decision.
So what is best of them for battery life and performance at cook rom?
(I think MP-decision is best for Stock rom, correct me if I am wrong )
Intelliplug is a replacement for mp decision implemented by faux123 if im not wrong . It determines the behaviour of the cpu and gpu. Stock nexus and OG only have mp decision. Intelliplug is a better option
Sent from my Nexus 4 using XDA Premium HD app
mp-decision is better.
The only thing the Intelliplug do is causing lags, freezes and other annoying strange things.
imho.
There's also msm_mpdecision (not to be confused with the mpdecision binary) by showp1984, which is pretty good. It has input boost and is the smoothest I've tried. I'd give that a shot depending on what kernel you're running. In trickster, it'll be a menu in specific called MSM-MPDECISION control (or something like that). CPUQuiet is supposed to be good as well, but I haven't personally run it. Auto_hotplug and mako_hotplug in faux and matr1x are typically better for battery than others, but are not quite as smooth.

If you are comparing stock vs N4, yes, they are different; stock should actually be a bit better since Qualcomm doesn't include certain things on Nexus devices. On CM, the mpdecision binary used I believe is from N4 4.2.

I don't see anything that is making Qualcomm MP-Decision better than Faux123 custom Intelliplug driver His hotplug driver is everything that MP-Decision is lacking of + more battery friendly and less heat generating..
MPDecision is much more aggressive in terms of changing CPU frequency (automatically goes to 1026 when input is detected). IntelliPlug is more for battery than performance. For performance, I suggest MSM-MPDecision from showp1984 (it's on most of my kernels and a couple others), which performs similarly to the mpdecision binary in terms of boosting frequencies and raw performance, but is customizable. You can change the frequency for input boost or turn it off altogether. There's a bunch of different settings you can play around with.
CPUQuiet also is one of the better performing hotplug drivers. I don't know quite as much about how it works, but it was made by NVidia and ported to Snapdragon by maxwen and has a set of governors which keep the CPU running at optimal frequencies for battery and performance.
In my opinion Intelliplug is extremely finicky and unpredictable. I get much better battery life with mpdecision.
I am a little newbie on this, so may i ask a question?
How can i install MP-decision?
Is it built-in on a kernel or do i have to download it seperately?
any body can completely explain what relay MP-decision and Intelliplug do? or any body know where I can read complete documentation of those?

MPdecision
Guys,
In my humble opinion what i have noticed is - when you enable a mpdecision i.e.on in the cpu, based on your cpu gov settings say for performance - one core of your cpu will always be at 100% and based on the activities it will switch on or off, the other cores.
When your cpu gov settings are interactively managed, again one of your core will be working and based on the certain % say 79 or 80,it will switch on the other cores.
If you deactivate mpdecision then almost all your cores will be active at any given time. But may not run as high as in enabled state.
So if you are one of those who cares about your cpu heating and don't use cpu tuners or sleepers. Set it off.
If you are into gaming and very smooth ui experience and doesn't bother about battery drain, switch it on.
I have enabled the settings and use custimized task scripts to reduce the frequency of the core as soon as i switch off the screen.

based on what you said on the rest of the post, shouldnt it be the opposite?
I recently rooted and installed a custom Rom and ElementalEx Kernel. I noticed that the default profiler for the Pixel XL is something called sched which appears to be a fairly conservative governor. I changed it to interactive which I normally use on other phones and battery life suffered considerably. I switched it back to sched and cpu frequencies are much lower but I don't notice any drop in performance. I tried researching sched but haven't found much. Anyone know how this governor works?
Sched is the most efficient governor for our pixel.
The real question is why do you want to change the governor? If you really want some things to mess with to increase battery and/or performance then check out "L speed (boost&battery)" in the play store. And No, this isn't shameless advertising either, the dev is right here in our forums.

It was a reflex reaction because I'm used to using Interactive and the CPU frequencies seemed really low compared with what I would see on the 6P. Those frequencies on the 6P would result in a noticable performance lag. But I guess the phone design is really different so you can't compare them that way. I'll check out L Speed. Never heard of it. Thanks.

Same. Coming from the 6p / 5x scene. The best governor was interactive, especially due to all the tweaks and changes that could be applied to the governor (like on ElementalX).
But no, pixel is almost dedicated to sched. I honestly don't think anyone else is running anything else and getting decent results from it
Pixel/XL Uses EAS so governors like Sched, Schedutil etc etc. Meanwhile every other Android device uses HMP your regular governors like Interactive, Ondemand, performance, conservative etc
So it's recommended to use Sched as the defualt but you can learn more about EAS here Also Freak07 has some great info on EAS and it's govenors here

All kinds of us are running schedutil gov on custom kernels. It's the next iteration of EAS sched gov. Better performance than sched.
Yeah same here, I would always use L Speed or some different governor on previous phones than default, cause default was always not the most efficient, both performance and battery backup wise, but on Pixel there is no need. In fact devs have suggested us to use the default Sched governor, so I am sticking with it.
Anyone on ElementalEx change any settings other than the governor to improve performance on the Pixel XL? A lot of the available settings are different than I'm used to.
Hi, everyone I'm s7edge owner would like to use a the Google pixel governor, can someone show me the direction please? Thanks

I think the devs suggest using the sched governor because they are either too lazy or not knowledgeable enough to create other governors that are compatible with the Pixel. The sched governor is far from efficient. It's clearly a performance based governor and it allows the Pixel battery and CPU to get very hot very quickly. The Pixel CPU can get to 130F just performing what most people would consider standard tasks on their phones. I'm not even talking about gaming or anything remotely CPU intensive. How long do you think these phones are actually going to last when they heat up so much?
What's the difference between sched and schedutil? I saw schedutil is default on the ElementalX for !y Pixel 2 XL.
