SysTune
Optimize under the hood of your system!



** Root Rights required!!! **

This is a system tuning and tweaking tool for advanced users with root access. It allows you to change various system settings to optimize your system.

This is my very first App on the Market. I am open for feedback and try at my best to solve any requests if possible.

It is very advised to properly inform yourself about those settings as i do not take any responsability for any damamge to your device.


NEW FEATURE
Changing priority of processes allows you to prevent lagging or other issues e.g. when a back ground process slow down your phone or you forground app has struggles to do its fluently.

See Help Tab for more informations before using this feature! More Informations and a small Guide will be available in the second or third post in the next days.

Note: The background service for monitoring processes to renice them causes no increased battery drain!

Features:

• Changing min/max CPU frequency
• Changing cpu governor
• Changing advanced governor settings
• Voltage Control (SVS and HAVS supported)
• Block device settings like IO-Scheduler
• Kernel (Scheduler) Tweaks
• VM Tweaks
• Changing priorities of active processes (renice)
• Apply on Boot
• Mulit-Core / -CPU support
• Realtime CPU Clock Speed and "Time in State"-View of each Core/CPU
• Save and load settings individually for each tab (press Menu).
• Multi-Core/-CPU supporting CPU Stress Test (New)
• Safe Mode ( see in-app Help for Informations )
• ..... more to come!

NOTE: The availability of the features depends on your system. E.g. if your installed kernel does not provide access to VDD Levels voltage control than it won't be available.

After installation take your time and read the informations on the Help-Tab.

Download User Settings

This is a section with user contributed settings files for SysTune. Anyone can submit their settings via attachment to a post.
Though i beg to follow some basic rules:

• Tell which device, rom (version) and Kernel used
• IMPORTANT: Date (and optinal a version number) of your settings. So we now if there was a modification meanwhile!
• Short but clear explenation why you use this values
• What you did to come to the conclusion to use them
• [OPTIONAL] What you changed over the default values of your rom/kernel. (note which were the default values before the change!)

Please follow the rules to make it easier for others to judge if your settings are usefull for them.

• A user's settings for CM 10.1 for DHD rom:
  • Device: Desire HD, Rom: [ROM][UNOFFICIAL] CyanogenMod 10.1 Nightlies / M-Series - nightly from 20.02.2013
  • Date: Feb., 20, 2013
  • No renicing used anymore
  • Using stock clocks and ondemand governor.
  • Ondemand Governor settings
  • Misc settings
• A user's settings:
  • Device: Desire HD, Rom: SCI MIUI 1.11.25v1.0, Kernel: lordmod 8.5 cfs
  • Date: Nov., 30, 2011
  • Smoother and more battery friendly then default values.
  • I am using several benchmark apps to test different aspects. Also i am testing overall daily usage. For reliable tests i have some things i repeat to see how the impact of changes of the settings is. Benchmarks used are: NenaMark 2, An3DBenchXL, Quadrant (not very good though), AnTuTu, TAP Benchmark (for internal flash memory), SD Tools (for sd card).
  • CPU Settings: ondemand
  • Governor settings
  • Misc settings
    
  • For BFS kernel version use set rr_interval=2 in the misc tab under kernel settings. But for my Rom i stick to CFS currently.

Renice Settings

Some general tips:
The priorities influence the behaviour when two processes that want to do some work at the same time. It influences which process will get more cpu time, thus it may cause lags for the lower priority process.

So in general the default priority of 0 is the one you should keep for most of the processes. But there are some processes that maybe you are not using all the time, but when you want them to use you want them fast and lag free.An example for this is the "phone" process but also the systemui process can improve the behaviour of your GUI in general.

On the other side there are processes that need to do some work in the background. Such process could slow down or cause lags on your currently used app / foreground process. An example for this is the media scanner "android.process.media". Think of reducing its priority to prevent slowing down other things. You won't care if the media scan in the background would need a minute longer to finish if you get a more fluent foreground app

I also got user reports for apps like media players that since they increased their priority now work flawless.

• A User's Renice Settings 12 Dec. 2011 (see used rom etc. above!)
  Notess:
  • I increased the the priority for processes that need to respond fast when they actually are needed, like the phone process.
  • I also increased the priority of my keyoard app to improve its pop upp in some seldom but annoying situations. If you use more than one keyboard app just set an increased value of all of them. As you never will use two at the same time you do not need to decrease the priority of one of them
  • Beside of other stuff i also increased the priority of my used launcher, adw ex. Add your launcher or replace my entry with one for your launcher. I think com.android.launcher is the process name for the standard launcher. But as you are using it you can see its process in the list of the "add" dialog.

strange, where has the reply of user sergeybrin gone?

anyway, am open for suggestions and reports of issues. if anybody has tried it found that something is not working for their phone i would be thankfull to know what so i am able to fix that.

Optimal settings for LordMod 7.2BFS kernel

---

Hi a user thanks for the great app.
I'm on Alienmod's CM7 (nightly 208) with LordMod's 7.2BFS kernel and was wondering what the optimum settings are in the "Governor" tab?

I looked at your MIUI thread and saw that you have:

suspend_freq @ 614400
down_differential @ 15
sampling_down_factor @ 50
ignore_nice_load @ 0
up_threshold @ 85
powersave_bias @ 50
sampling_rate @ 80,000
io_is_busy @ 1

so I am using these settings and everything seems ok.. (im using ondemandX 230400min and 1152000max).

Are these settings ok to use for my ROM or are there better settings?
Also i'm currently -50mV undervolted.

Thanks!!

this are still the settings i use and i think they pretty much optimal for aosp roms for the dhd. edit: except that my max fre is 1075MHz

regarding undervolting: carefull and you should only undervolt one freq at a time then test that extesively (e.g. by setting min and max freq to it and running something stressing the cpu for a longer time).

in general it is only needed to undervolt the freqs close to your set max freq as undervolting only makes a significant difference on consumption if there is high load. and on high load your phone switches to higher freqs

p.s. glad you are happy with the app.

I recently discovered due to a nice customer that despite googles license code documentation the licensing server do not provide validation timeout infos. hence some customers may observed that the app failed licensing on connection issues.

Google documentation on this claimed it should work as i expected but it doesn't. Hence i just fixed this now myself and want to apologise for any issues caused by this. I will improve this further in the near future.

Great App

thank you!

@all: There are many roms out there with broken busybox installations. i already have some workaround built in to handle that. i just discovered that one of my workaround had a typo. so if someone tried the app and saw it not working as it should it probably got fixed with the most recent update to 1.2.6.

i would like to see why some people are cancelling the purchase as it is already possible to see exactly what it does on the screen shots. If something is not working as it should i can't fix it without feedback. too many roms and devices out there to have them all and being able to test against.

I've tested unsuccessfully on the tmo g2x running EaglesBlood latest (cm7 based) and the dragon kernal. By testing I mean the drop downs for CPU Max and min show a thin white bar with nothing selectable.
Edit: tested with another kernal, and my guess is they don't support your method for accessing the processors... but I've been wrong before.

thank you for the feedback. But i need the info provided by the feedback button. Please use the feedback button on the help tab to collect some information and send it via email.

if you do not want to send me an email you canstill use that button. it will collect some infos and save them on your sdcard as "systune.inf". cancel the email that opens up. the file will still remain on your sdcard.

attach it here to your next post (maybe you need to rename its extension to .txt). without that info there is nothing i could do.

p.s. you can look into that file to verify that nothing confidential is collected. it is plain text.

EDIT: i saw your edit. does this mean with the other kernel it worked? basically your guessing seems right. but the thing is that my method to acces this values is the ONLY one possible. it is done through the kernel exported values in the sysfs. this is basically the only way to access kernel values at runtime. this custom kernel(s) you are using are either not exporting these stuff or they are doing wrong (by convention).
in the latter case at least i could do a workaround to compensate for their wrong placement of the stuff.
