GOVERNOR EXPLANATIONS:
'minmax' - this driver tries to minimize the frequency jumps by limiting
the the selected frequencies to either the min or the max frequency of
the policy. The frequency is selected according to the load.
Originally posted by erasmux -
smartass - is based on the concept of the interactive governor.
I have always agreed that in theory the way interactive works - by taking over the idle loop - is very attractive. I have never managed to tweak it so it would behave decently in real life. Smartass is a complete rewrite of the code plus more. I think its a success. Performance is on par with the "old" minmax and I think smartass is a bit more responsive. Battery life is hard to quantify precisely but it does spend much more time at the lower frequencies.
Smartass will also cap the max frequency when sleeping to 352Mhz (or if your min frequency is higher than 352 - why?! - it will cap it to your min frequency). Lets take for example the 528/176 kernel, it will sleep at 352/176. No need for sleep profiles any more!
Originally posted by scaryghoul -
Scary - A new governor I wrote based on conservative with some smartass features, it scales accordingly to conservatives laws. So it will start from the bottom, take a load sample, if it's above the upthreshold, ramp up only one speed at a time, and ramp down one at a time. It will automatically cap the off screen speeds to 245Mhz, and if your min freq is higher than 245mhz, it will reset the min to 120mhz while screen is off and restore it upon screen awakening, and still scale accordingly to conservatives laws. So it spends most of its time at lower frequencies. The goal of this is to get the best battery life with decent performance. It will give the same performance as conservative right now, it will get tweaked over time.

I hope to add some more user-friendly control to UV/OV, hopefully in the next version.
I tested this on my device, but as stated below, there's no guarantee it will work on yours.
This kernel should only really be used on CM7 nightly 78 and above. Not sure what'll happen if you use it on earlier nightlies, but it's definitely not supported.
Performance should be as good as or better than stock kernel.

Great work bro! I'll def. give it a shot right now!

Thanks, gonna give this a try.

You sir just made my day. So we will need to use terminal to edit our UV values until you get that dealt with, correct? Will they persist through a reboot or not?

Now this is what I was waiting for
Thank you

not to get off-topic, but your sig says youre using the pyro kernel with the CM nightlies. You do know that blah said the recent nightlies are no longer compatible with that kernel, due to the CM kernel being rebased on a different kernel than the base of the pyro kernel. However, I can attest that this kernel DOES work with both nightlies and pyromod

Thanks for the 1.9GHz Will test in conjunction with the latest CM7 nightly when I get home!

Thanks. Flashed and working great. On build 91

I'm having the same issue.

I know the og post said that this should mainly be used with CM7 nightlies, but I decided to give it a try with the MIUI ROM that I'm using. No dice. Wouldn't even load the bootscreen. I'm thinking I may flash over to the current CM7 nightly to give it a try though.

Im using the MIUI rom on my G2 and the smartass kernal... Freakin great if you ask me. I have about 30 to 35% battery and its about to be 1010 pm and i unplugged from charger at 730 am. Beat kernal so far.

I think it's just under a meg, for a total of 4 megs of GPU ram instead of 3 megs.
I don't know what kind of performance gain comes from it.. I'll have to benchmark it and let you guys know.
The added memory doesn't look like it was being used by anything else, though.

[Q] What app do you overclock with?

I am playing around with some other OC/UV apps other than SetCPU and was wondering, for those who do OC /UV /UC, what app do you prefer?
ive tried out (so far)
SetCPU
Voltage Control Extreme
AnTuTu CPU Master Pro
CPU Control Pro
ROM Toolbox Pro

I've had my A100 for a few weeks, up to now I've used AnTuTu CPU Master Pro to overclock and undervolt, hasn't failed me yet, originally used my ROMs built in settings but that began to be a bit tedious, constantly having to dig through my settings for it got a bit old, a convenient shortcut to the performance settings would be just dandy.

I found overclocking the GPU helps a lot more. There is a kernel for jellybean rom (a.k.a. CM10) and may work for ICS and the GPU overclock helps a lot. Use built in CM over clocker @ 1.5 GHz and GPU @ <400 MHz or whatever speed the kernel builder put it at. The original GPU clock speed was around 350 MHz or something so that is a substantial boost in terms of speed. Other then some heating when playing games no problems and perfectly stable. Battery doesn't seem to drop a bit maybe 1 or 2% faster.

Quadrant scores chart - Xperia S/SL, Acro S, Ion

Hi!
Click on the picture to see the scores:
​
If you click on my signature picture you will be also led to my Excel table with Quadrant scores for every ROM I tested on my Xperia S. I ran every benchmark twice for each ROM so that's why there are duplicates.
It is pretty detailed and can help recognize progress in ROMs between versions or between stock vs. custom based ROMs.
But, I don't have much time to test every individual ROM here so I would be glad if you could help me.
Post your Quadrant scores here. Screenshot would be preferable.
Also I could use following infomation:
Which phone (S, Acro S, Ion) - must have!
Which ROM
Which kernel (preloaded or custom)
CPU and I/O scheduler
Android version
Any type of overclock
I recommend running benchmarks more than once to cross out any weird scores and to get as precise results as possible.
This is NOT a competition for highest score, this is just for comparison between ROMs and performance settings just to have a clearer picture which ROM has better drivers, more tweaked kernel, better FPS for games etc.
If you have some ideas, new benchmark tools (which are consistent and as accurate as it gets) - post it and we'll see what can I do.
Don't use I/O hacks because it is very easy to spot them. Any weird score will be dismissed.
Updates are almost on daily basis with constant little tweaks to make it more detailed but as clean as possible. Everyone hates cluttered Excel tables
Explanations:
Cells with red edges have further explanations if you hover over them;
Headers have sort buttons - you can sort whatever you want!;
On the right side is link that switches between scores and charts;
You are free to download this table but please ask me if you want to modify it and redistribute further.

No ICS? By the way, on fully stock ICS (daily driver that I used for more than a year straight, more than 30 installed apps, social network crap disabled) I get around 3350. I ran it right now and got 3318 (6448,2914, 4347,1000,1881).
Looks like JB's only improvement is in I/O (and only on the stock based JellySlim), everything else is same or inferior to stock ICS.
Whelp.

Of course I can put ICS scores but I was focused on JB performance because of quite a number of different ROMs that are posted here.

Is this Xperia S or? Because in your sig there is LT28h (ion).

Xperia S, Trinity ROM 2.6, Forzaferrarileo v4 as my kernel. 30-1728mhz, interactive, sio. GPU OC on max (266mhz 2D, 320mhz 3D). 1500kb as sd cache.
I've also cleaned up a lot of **** from the rom. It weights around 71mb right now (had 65mb before installing gapps)
Powered by TVR with Android 4.1.2 on the board.

Please, can anyone test is my table working good? I made some changes, Scores and Graphs are in separate sheets but I placed link on right side of table/graphs to move from one to another. Also, are there any glitches / bad formatting?
I see everything fine but that does not mean that you folks see it the same way. At last, it is Microsoft

To my understanding, (replaces hotplug control) and smooths out the way the cores work together and controls them more efficient. On paper it is supposed to be battery friendly without reducing performance by a great deal.

Oh? I like the sound of that. I'll test them both heavily for a couple of days and report my findings.
--edit--
So far it seems that CPU quiet will definitely eat up more battery life than Intelliplug. It likes to kick on all 4 cores with at least 3 of them kicking at 1.7GHz with the slightest touch. This is with mpdecision on and off. Dropped 4% in the last half hour with full screen on and and just playing with the settings through trickstermod. Bad for tge 9300mAh ZL battery in which i could do the same with maybe 1% drop. Just a heads up! Switching back to the intelliplug one for awhile.

Oh? I like the sound of that. I'll test them both heavily for a couple of days and report my findings.
--edit--
So far it seems that CPU quiet will definitely eat up more battery life than Intelliplug. It likes to kick on all 4 cores with at least 3 of them kicking at 1.7GHz with the slightest touch. This is with mpdecision on and off. Dropped 4% in the last half hour with full screen on and and just playing with the settings through trickstermod. Bad for tge 9300mAh ZL battery in which i could do the same with maybe 1% drop. Just a heads up! Switching back to the intelliplug one for awhile.

Might be for performance only then. I swear it was for battery though. Oh well, I seem to prefer the other option myself as well. I kept accidentally double tapping my screen in my pocket and was wondering why my battery was draining, lol.

Can't wait to OC my E980
Flashing as I type...

I have only succumb to one bootloop... And that was pushing this baby to her max. I OC'd to the max and ran Antutu... Got about halfway and just stopped. I'm trying to get optimal speed and battery. Anyone have any good settings?

Use the terminal emulator in ROM toolbox and run: dmesg | grep PVS
This will reply with a number from 0-4. 0 being slowest binned and 4 being fastest. The lower the number, the higher the voltage you need for higher frequencies to run with stability. I learned this through my old LGOG. Not all processors are made the same so this WILL vary between different devices of the same model. If the value is between 0-2, you will need to up the voltages of frequencies higher than the stock 1.7GHz otherwise you WILL end up with boot loops and crashes. 3 and 4, probably not. With fast (3), the stock voltages for frequencies that are included with this kernel will most likely work without issue. I have a fast binned CPU and have no issues. I have a fast binned CPU and haven't had any problems. Faster (4) should actually be able to UV the frequencies above 1.7GHz without these issues. In stock ROMs with the stock kernel, this is already taken into account and will UV automatically according to your CPUs binning. This will also determine how well your device handles lower frequencies. Mine, being a 3, handles 162MHz just fine. But I end up getting SoD (Sleep of Death) meaning the screen won't turn on after turning it off for some time, at 81MHz. From my knowledge, 81MHz minimum will work on 4s which the developer of this kernel probably has. Why put in something you've had time to test and it just NOT work?

Code:
<6>[ 0.236267 / 01-01 00:00:00.230] acpuclk-8064 acpuclk-8064: ACPU PVS: 4
It restarts on Antutu if I overclock it a little with the default voltages...
BTW, anyone knows what app can edit the voltage for the GPU?

Does it actually support exfat? I have a 64gb microsd which works just fine with the CM11 kernel but it is not recognized by any of the two variants posted here for KK.
Thanks

Trickstermod is my app of choice for kernel customizations.
EXFat support has to be built directly into the ROM or can be installed by a mod. As far as I know, none exist for our device. There are a number of free programs for windows that allow you to format a 64gb sdcard to fat32 which will work on ANY ROM and ANY device running Android. I've had my 64gb class 10 SanDisk card formatted to Fat32 since my Atrix HD days and it still works on my OGP.
I posted a thread here in the general section about OC/voltages. Just waiting on someone to post the voltages on the stock kernel before I further my research into creating a list of voltages that will support up to 2.3GHz on our device.

I don't think it will mate. However, if you read through the original forum it was posted on (found in OP at the bottom of the page) you might find someone made a modded version, as someone did get it going with MIUI and some others.
For all of you OC fans or anybody that wants the most out of the kernel, read through the original forum (found in OP at the bottom of the page) as well and you can see other people that have played with the settings and have given screenies for it. There is so many helpful tips and setups through those pages, plus it has other cool stuff so have a read

Man this is really exciting!
Thanks Uppon2 can't wait to give this a go.

This is no longer maintained by the dev right?

Which is the best kernel out of the 2 for kitkat? And how can I turn off the sweep2wake and tap2wake functions??

[APP] GPU Voltage Control App for the AKLU kernels [1.2]

GPU Voltage Control App for the AKLU kernels
To God be the glory! Finally a way to control the voltage of the GPU on AKLU Samsung Galaxy S4 kernels!
While enrolled in an Android app developer course by Rob Perceval, I have used my limited skills to create this simple app which allows you to over volt, under volt, or reset the voltage to defaults for the AKLU kernels on the Samsung Galaxy S4!
It *could* possibly work on other S4 kernels that use ktoonsez's GPU voltage controlling code, but I don't recommend it. However, if you do try it on another S4 kernel, and it is successful, please let me know, or post it here.
The toast pop-up will tell you your current status (default, over volted, or under volted), and the buttons allow you to set a new status.
SAFETY:
#1. The app is programmed to check if you have @ktoonsez 's GPU voltage controlling code, and if you do not, the app will immediately close to prevent a user from writing things to the /sys directory that they shouldn't.
#2. While this is inherently dangerous, the app is set to only make a small, fixed adjustment of 10 mV. I have played with numbers and I believe that this is the "safest" option possible, while potentially allowing for some gain.
That being said, USE WITH CAUTION.
This app requires root privileges and permission to read/write to your phone so it can check for the current GPU settings and write new ones.
Also, at this time the app will not automatically set the voltage again after a reboot. You must manually choose to enable this after every boot.
Enjoy, and feel free to leave an on topic comment! Especially if you tried it with games, videos, or just daily driving.
Download:
Google Play Store: https://play.google.com/store/apps/details?id=com.alaskalinuxuser.s4gpuvoltagecontrol
- Or in the Source folder under "app".
Source: https://github.com/alaskalinuxuser/app_s4_gpu_voltage_control
I give full permission for anyone to use or abuse the source code in any way they see fit. I have put comments in the code.
Change log:
20170727
- Update to version 1.2
- Can now change by -40 mV to +50 mV!
20161125
- Initial release.

Screenshots!

Also a big thanks to:
@faux123 and @javelinanddart and @ktoonsez who did all the "real work"!
For the code that allows us to change the GPU voltage! Without these guys, this app would be useless!

GPU voltage was not faux123, it was @ktoonsez
https://github.com/javelinanddart/a...mmit/79361b0fcdbf6eb6df45286082ad549bbb31c75e
Also, I simply played around with the sysfs methods and placement, ktoonsez did all of the real work

Thanks for the clarification! I have updated the thanks post. I based it off of the github commits that I borrowed the code from for the kernel, which was faux123's.

The AKLU kernel for AOKP Nougat (7.1.2) has been updated to work with this app, be sure to give it a try!

Praise God, new update in the OP!
I've completely redone the GPU control app. If you have the old version, you could only over or under volt the GPU by 10 mV. Now you can over/under by -40/+50 mV! The interface has been improved as well, plus, now you can see the voltages you are controlling... It's a big improvement over the old app, so feel free to give it a try! See the OP for details, now available for download on the Play Store, or from the GitHub app directory.

I ran some benchmarks with AnTuTu before and after making some adjustments. While over volted at +50 mV, the 3d score was 2319. While under volted at -40 mV, the 3d score was only 2282. Not a huge difference, but it is noteworthy. That's a 37 point difference on the score. Probably not perceptible, but interesting none the less. The overall AnTuTu score (all other things being equal) was 36342 with over volting and 36334 while under volting. The limits that I set seem to be safe, in that the benchmark did not cause a crash, but your results may vary.
I also gave time for the phone to cool down between benchmarks, since heat makes a difference.

Any comments from the crowd on GPU voltage control? Any performance issues when gaming?

First of all, thanks for bringing this , that's what I wanted! I did -40 for the GPU. I think it runs cooler but does not affect performance (visually). Not sure if it is a placebo for the temperature

That follows the general theory, when undervolted, it should be cooler.
Thanks for the feedback! Glad you like it!
