[Q] System Tuner Settings - Nexus 7 Q&A, Help & Troubleshooting

You can search all you want and still come up short, I'm trying to use system tuner to change the cpu and gpu settings and I cant find any help on how to use this app. Im running the latest Kaos Droid rom for 4.1.2, the latest Motley kernel and twrp, props to all developers:good:. Im looking for what the optimal settings are and how to use system tuner to change them. Can someone tell me or show me the right thread that can help? Im not sure what the min/max cpu settings should be and I cant seem to find where to change the gpu settings. We are all noobs at some point. I just want to beef my nexus up a little, nothing crazy.

aww for real?

I wouldn't use system tuner for this because it doesn't have the ability to change the GPU speed. I'd recommend TricksterMOD which is available here for free. Depending on your kernel (not sure if motley's kernel has configurable GPU now, it didn't when I used it) you can change different settings. It is personally up to you how you want to configure your device and change things depending on how it runs. Anyway, I'll give you an idea of my settings that I have changed.
CPU - Governor is Interactive (my kernels default but another alternative would be ondemand) running @ 102mhz min - 1600mhz max
IO - Governor is deadline (again default but imo the only one you should use) with cache at 1024.
GPU - 600mhz
VOLTAGES - My kernels defaults.
Make sure that you set the settings to be applied at boot (I use a delay of 1 because it didn't seem to apply without it) and also make sure your kernel has the powerHAL fix included, or else (in the case of trinity kernel) you will need to download this file (this is for Android 4.2.x). This will allow your CPU overclock to stick and not be reset to stock.
Hopefully this helps! But again, just play around with your frequency's and maybe look into voltage tweaking to get your personal balance between performance and power consumption. And if you are going for performance, I'd look at turning off fsync and using the ext4 mount script to boost your I/O dramatically (this will result in things such as faster app installs)

smt8544 thanks alot man! now I can start somewhere, I didnt wanna do anything stupid without some knowledge, I appreciate it!

Why no governor is stayed after a reboot?

As the title says. No governor, be it on-demand or performance, doesn't stay after a reboot. I've tried Adam, Perseus, issue persists on both of them! Is this because of this new 4.3? If I remember correctly this wasn't a problem on 4.2! I've tried with SetCPU, No Frills, nothing...I always used performance, now I can't set it and it bothers me very much....
Anyone?

Have you got more than one app actively trying to set the governor ? You've said you're using SetCPU, but make sure the rom (Performance Control for example) or kernel doesn't have an app that's also trying to set the governor on boot for example. If they are, disable those & then try with SetCPU.

Well I have tried with either Adam or Perseus, and in that case S-Tweaks and Synapse are automatically installed respectively. And I don't see there's any setting under those apps to change Governor! So I am forced to use SetCPU, are you saying I should uninstall S-Tweaks or Synapse in order to get SetCPU working properly? Because there's no visible settings under S-Tweaks or Synapse to change governor but there could/must be a hidden setting there which changes Governor at each reboot! and probably conflicts with SetCPU?
Actually, first up, try clearing cache/data on SetCPU, reboot, apply settings you want, reboot & see if they stick.
Then try uninstalling those other apps which might be conflicting. Also, check in rom settings to see if you have anything like Performance Control which might be setting something at boot. Also check to see if you have an init.d folder/if there's any scripts lurking in there which might be causing problems.

Nah, tried everything, no profile sticks, even master wiped the device with full stock ROM and kernel, nothing. It's not actually a reboot needed for the default governor/settings to take place, if I just turn the screen off and turn it back on after a minute or so the set governor by me doesn't stick.
I am quite sure this is how it is suppose to be, but whatever, I don't like it. The fluidity I have seen with performance, well nothing could beat it. Maybe the CPU architecture of i9500 is the thing to blame here. Damn...
That's really weird. Maybe try another app other than SetCPU (or a bunch of them) ? Some kernels have variables that can't be set by the user or you can set them but they immediately go back to whatever setting the dev who made the kernel wants them to be at (some individual governor settings like sampling rates/etc), but setting the actual governor shouldn't be one of those. If the governor is available in the kernel, you should be able to both set it 'on the fly' and set it on boot.

Nah, not really weird as I understand it now. CPU hits throttle temp at 1.6 GHz and automatically defaults out at a lower clock rate, in this case 800 MHz. That's just too bad for me anyway, I have never used anything besides performance, now I am forced to use something else! I wonder how come no one has mentioned this yet!

Kernel Settings

Hey Guys,
i have a question
Well how you mod your kernel e.g Render Kernel for more battery ?
Cause i can flast the render Kernel but didn't have a clue what i need to change in the Kernel settings with programms like synapse and so...
Also i didn't find a tutorial for moding the settings of a kernel
It would be nice if some one would provide me the basics of that cause as i say above i'm a noob in moding a kernel due to the fact that i didn't ever done it.
Thanks
If you dont know anything about setting parameter in Synapse then i suggest you just set up max speed of cpu not lower then 1.7Ghz and min speed above 192Mhz. For more battery saving go to undervolt tab and put -25mv for overall step. NEVER OVERVOLT it unless you know what youre doing.

Phone slow after root

I rooted and am running tek s ROM. The phone has been super laggy and slow since I flashed that ROM. Any advice.
Have you switched the governor to interactive or on-demand? That's the most important piece. The below link has a bunch of tips (universal to qualcomm/US S7 and S7e) to improve performance.

Bug #1: Phone is laggy after rooting the phone/Battery is down the tank.
Fix: The phone is (partially) lagging because the ENG bootloader automatically sets the CPU governor to "Performance." While this is supposed to lock the CPU frequency at the maximum values, it does cause a lot of heat and possibly throttling. Additionally, the max core clocks are set to 1.593Ghz instead of their actual maximums. Not every CPU Tuner will allow you to set the big cores separately, so look around for one that does if you don't want to use Kernel Toolkit.
First, use Flashify to flash one of two zips provided by psouza4 on our sister Verizon Galaxy S7 (Edge) threads.
1. Kernel fixes & tweaks V15
2. Kernel fixes, tweaks, & Debloater
You need only flash one of these two zips. One additionally debloats the system, one does not. Choose whichever suits your needs.
What the zips do:
CLICK TO SHOW CONTENT
Next, install a CPU Tuner utility like Kernel Toolkit, then change the governor from "Performance" to "Interactive." Also change the max CPU frequency of the little cores to 1.593Ghz and the big cores to 2.150Ghz while you're at it. Leave the cores at their default minimum frequency. This will go a long way to improving the speed of the phone. Also make sure you that have the new settings to apply on boot. Every kernel manager should have this option somewhere.
Note: Although the max frequency in the settings screen will drop to some number, as long as you can see the CPU ramp up to the new settings in the information screen, then everything is fine. You can test the max frequency by turning the screen off and then back on.
Then, install sEFix and set entropy to "Ultra."
Lastly, install L Speed and:
Code:
-Main Tweaks: Turn on
-Battery Improvement
-OOM Killer
-Kernel Tweaks - "Light"
-CPU Tuner: Turn on
-CPU Optimizer
-LNET Optimizer: Turn on
-Google DNS
-Faster Streaming
-Faster Dormancy
-IO Tweaks: Turn on
-IO Boost
-Partition Remount
-RAM Manager
-Balanced
-Seeder
-Moderate
Literally the first bug and fix on the guide.

​Hi there!
Because of numerous issues found in 3.4.113 kernel, I'm temporarily moving to development on 3.0.101 base.
What is difference between chrono kernel (CK) and CK refresh build? CK was mostly tested on MM-based ROMs, but appeared not to work stably on Android 4.4.x. Aim of this build is to properly enable support for older ROMs (like kitkat), and when done, merge these changes to 3.4.113 kernel.
This build is based upon chrono kernel r4.1 build, so to avoid versions confusion, I'm creating a separate topic.
Features:
CPU, GPU and DDR OC support
more governors and I/O schedulers
Lite kernel - some kernel features moved as modules
F2FS support
ABB-charger tweaks
many others features and tweaks...

R4.6.2
rebased to CM14.1 branch (added support for 6.0.1 and 7.1.2 ROMs)
R4.6.1
fixed CPU OC instabilities
LCDCLK is adjusted to fix tearing issues *
adjusted Dynamic CPU governor tunables for a better battery live
adjusted PowerHAL profiles **
genfstab: storages swap is disabled by default (remove /ramdisk/fstab_specs.txt before flashing to take this change in an effect)
updated temporary kernel zip
* tested with apps like Impossible Game, a display tearings are mostly resolved here. Apps like Youtube, though, might still causing tearings when playing video.
** the minimum CPU freq is set to 400 MHz. I've decided to use it as a default since 200 and 400 MHz CPUfreq steps are anyway using the same voltage, so unless you're undervolting the CPU, there won't be any significant difference in a battery drain.
R4.6
updated to r4.6 LowMemoryKiller implementation - best so far!
Disabled HighMem
removed some CPUfreq steps *
Dynamic governor: parameters are tuned for the better performance (credits: @ace2nutzer)
Added performance profiles (the corresponding parameters can be found in /ramdisk/perf.profiles.rc)
Other updates from r4.6 (various updates from LK 3.4, tweaks etc)
* Avalable CPU frequency steps are: 200, 800, 1000, 1100, 1200, 1215 Mhz. I've decided just to give it a try - this is a necessary part of tuning the CPU governor. If anyone doesn't like that frequencies between 200 and 800 MHz were removed I can add them back, but until performance-related issues are not resolved I'd suggest just leave as it is.
R4.1
Initial build for janice (kernel sources based on Chrono Kernel r4.1)
LiveOPP: updated to r5.7.1 kernel version
Exfat: test fixes for Stock 4.1.2 ROM (not tested)
Enabled CONFIG_STE_TRACE_MODEM (test fix for Stock ROM incoming / outgoing calls)
Kexec: added janice support
Misc
Storages switch
By default, this kernel comes with internal and external storages switched. You can revert this behavior, by changing the line
Code:
use_swap=1
to
Code:
use_swap=0
in file /ramdisk/fstab_specs.txt and flashing the kernel package. This setting will remain until you format /ramdisk partition.
Thank you Chrono again.
So far I am still having issues with calls on 4.1.2 stock, I took another logcat in case would help you, and seems like phone can't enter deepsleep mode, but I will investigate further this issue with some days of usage.
I couldn't get exfat working, I took the exfat-fuse binary from /sbin in TWRP, then ran "exfat-fuse /dev/block/mmcblk1p1 /storage/extSdCard", tryed also with "mount.exfat-fuse etc etc", the fact is the card is correctly mounted and usable from recovery, but this does not matter after all.
The nice thing is I find multitasking working far better, phone seems to be more responsive in situations where more apps are running at the same time, this is very good to me!.
Another big point is installation went fine and recovery is working perfectly, so problems with possible bootloops are solved (and after some more usage I will go further to your more updated roms )
If there is something more to provide you, test or informations missing, please ask me Chrono
I tested chrono kernel r4.1 on Lineage OS 11.
-Compared to the previous chrono_kernel_r5.7.1, this is considerably slow, especially during the opening of apps like Settings, Contacts, Google News, Play store.
-If I set 1000 Mhz as maximum clock of the dynamic governor, the phone becomes slower and a bit hot on the back.
Multitasking is severely affected by that clock. Multitasking is more stable at 800 Mhz, despite it's still slow.
-If I reboot the phone, the maximum clock of 1000 Mhz is automatically resetted at 800 Mhz.
-If I attempt to reboot the phone in recovery mode from Lineage Os 11 ROM with the PC USB charging cable on, phone will shutdown instead. Disconnecting the charging cable before rebooting the phone in recovery mode is the only workaround. It doesn't happen with the Epirex Kernel, so I think it's related to your kernel.
In my attachment there is a meminfo that I took while the phone was under load.
If it isn't enough, I attached a full logcat. There are some errors and crashes.
@Pdevo, @isaak, thanks for testing!

Probably I've rushed things, or sort of. I had a hard time trying to find a considerably stable kernel 3.0.101 base (this one appeared to work stably, though not best, in terms of the performance). Nevertheless, the multitasking should already be better (at least better than in r5.7.1, as in this one LowMemoryKiller appeared not to work at all). I'm updating the sources to a new kernel base, r4.6 which should be even better in multitasking term.

It's a bug in CM11 ramdisk, I've took another one from Codina, and now this issue should be resolved as well.

I'm afraid that exfat driver built in the kernel is not compatible with this userspace mount.exfat-fuse utility. I won't be able to fix it, until I find a time to return to stock & rebuild either mount.exfat-fuse or kernel driver in order to make them compatible each with other.
As for the deepsleep issue, I can say that at least 4.4.4 is not affected by this bug. Try making sure that no apps are preventing deep sleep (Better battery stats or Wakelock detector can help in that).

Tested on Lineage Os 11 without CCleaner.
After flashing this new kernel I had to force a Media scan with Fx File Explorer (that detected over 300 changed files) because the phone was really slow. That was sufficient to speed up the multitasking that now it's much better than previous 4.1 build.
Additional observations:
- Do you think it's possible to improve Media scanner reactivity via kernel?
- Fx File Explorer detects my external sd card as Main storage and Media card as internal storage. This doesn't happen on Epirex kernel.
- Battery usage is higher than previous kernel. If I stay on a webpage in idle, after 30 seconds my battery decreases of one percentage point (i.e. from 70% to 69%). I noticed that a simple swipe on the screen jumps the current clock directly to the maximum frequency, this could be one of the reasons.
- There is only FIOPS as I/O Scheduler and I miss all the other schedulers.
I think you're on the right track!

I don't think it's possible. The only possible way is to overclock CPU, though it won't help much.

This is a default behaviour in Chrono Kernel. Because on codina we have only 4 Gb of available space, it makes sense just to remove internal storage partition and use the external one as primary. If anyone wants, I can revert this behavior. It's possible to switch storages back by editing file /ramdisk/fstab_specs.txt (set use_swap value to 0) and flashing a kernel package.

Ok, I'll consider of tuning CPU governor in order to provide more battery friendly setup. I was afraid that the battery usage might be too high, but that was a necessary evil, I guess. In the meantime, as a temporary workaround, the maximum CPU frequency can even be lowered to 800 MHz, it should be still fast enough.

To load more I/O schedulers, you can copy (or symlink) a module file to /system/lib/modules/autoload, then reboot the phone. This doesn't seem to work, a script that loads modules, is broken.
Because usually I don't change I/O scheduler, by default, no more I/O scheds are loaded. Do you have any preferred I/O scheds?

Personally I really appreciate and find useful the external sdcard storage as primary one, should be the default behaviour for me, it makes sense and also I never liked to have some files on one unit and some files on another one (download, pictures, recordings on extsdcard, apps folders, screens, other apps downloads etc on internal), I really like the idea of sdcard as main, like the old times of galaxy mini
Fiops to me is a fair good scheduler, maybe also noop would be useful, but I guess having as much things as modules as possible can help load only the strictly necessary, but I say this without dev knowledge.
I will test this build and especially the deepsleep issues, to see if there are apps causing phone not to sleep, the problem is I didn't add any app, just using the same enviroment that with cocore was going to deepsleep. I will report soon, anyway, good job chrono, keep it up

Yes, FIOPS is good. I just think that having 2 or 3 additional schedulers to select would be better for different uses.
In my previous post I replaced sioplus with zen, according to the conclusions of this guide. There is an useful (up to date) list of recommended IO schedulers, ordered for everyday usage, battery life, heavy multitasking, etc.
New build r4.6.1 is up!
Hey guys and sorry for having to wait that long for a new releases!
I'm still working on 3.4.x kernel - no great news here, but at least I've found a more less stable sources base, so the only what needed now, is a time to bring up some stability fixes and feature changes.
For now releasing a 3.0.101 kernel with some minor changes:
R4.6.1
fixed CPU OC instabilities
LCDCLK is adjusted to fix tearing issues *
adjusted Dynamic CPU governor tunables for a better battery live
adjusted PowerHAL profiles **
genfstab: storages swap is disabled by default (remove /ramdisk/fstab_specs.txt before flashing to take this change in an effect)

On Lineage OS 11:
Using more accurately the Performance function in Lineage Os Settings (an example here), there are different bugs:
1) Minimum CPU freq here is still set at 200 MHz after I flashed chrono kernel 4.6.1.. but this time I forgot to flash the temporary kernel before your kernel.
Anyway chrono kernel 4.6.1 was flashed without issue using TWRP 2.8.7.0.
2) Maximum CPU freq is automatically restored at 1000 Mhz after any reboot, even if I set 1200 Mhz (with any governor).
3) Deadline scheduler is automatically set after any reboot, even if I set FIOPS as default scheduler.
4) Dynamic governor is automatically set after any reboot, even if I set Zenx as default governor.
5) On the Performance UI, performance profile results automatically set on Balanced after any reboot, even if I set Power save as default (it may be reproducible with "Performance" option too, I didn't check).
UPDATE: I've reinstalled chrono kernel again and these behaviors still happen.
For me the minimum freq was correctly 400 mhz as expected, as always running on stock 4.1.2.
After two days of use I can say you are following the right path.
This time I wanted to remove every possible source of doubts and I went for a clean installation, so doing a complete reset and flashing your kernel, of course after the temporary one. I still have the phone not going to deepsleep and the call issues (basically it is impossible to do and receive phone calls on stock rom).
A part from these I can say I didn't noticed any other issue at all, finding memory management a little improved compared to previous release and battery life still good, considering the phone isn't going to sleep mode.
I think this will continue to improve and soon all these glitches will just be gone away, thank you so much chrono also hoping to settle for a bit on your ultimateROM, only waiting for the vibration working, because that is basically the only notification for me

Using more accurately the Performance function in Lineage Os Settings (an example here), there are different bugs:
1) Minimum CPU freq here is still set at 200 MHz after I flashed chrono kernel 4.6.1.. but this time I forgot to flash the temporary kernel before your kernel.
Anyway chrono kernel 4.6.1 was flashed without issue using TWRP 2.8.7.0.
2) Maximum CPU freq is automatically restored at 1000 Mhz after any reboot, even if I set 1200 Mhz (with any governor).
3) Deadline scheduler is automatically set after any reboot, even if I set FIOPS as default scheduler.
4) Dynamic governor is automatically set after any reboot, even if I set Zenx as default governor.
5) On the Performance UI, performance profile results automatically set on Balanced after any reboot, even if I set Power save as default (it may be reproducible with "Performance" option too, I didn't check).

1) Isn't an issue here, the showed CPU frequency is 200 MHz, but the actual CPU pll clock set at 400 MHz. Might be confusing, but yet that is better for a battery life.
2) These aren't really bugs, it's how LOS 11.0 performance profiles works. To change min / max CPU freq, you either need to edit /ramdisk/perf.profiles.rc (and set a custom values) or disable perf profiles. Actually there is one more way - to remove CPUfreq adjusting lines completely from that script - would anyone like this change introduced in a new release?
3-4) I've checked it right now - no issues for me... Have you set "apply on boot" checkbox?
5) It's a known bug of CM11 perf profiles. AFAIK, @ace2nutzer fixed this bug in his CM11 builds. @ace2nutzer, can you please remind how this could be worked around?

Honestly I don't know how to disable perf profiles. If it's a simple thing to do (like a command or two to execute), please tell me how to do it because it's enough for me, otherwise I'd like to try the third way and see.

Yes, "Set on boot" options are correctly set for both Processor and I/O Scheduler.
And I keep "Enable per-app profiles" option turned off.
@ChronoMonochrome
UPDATE 1: It occurs only randomly and with particular combinations. The best way to reproduce is to set these, one at a time:
1) Zenx as governor, min. 200 max 800, Noops scheduler. Reboot.
2) Zenx as governor, min. 200 max 800, Fiops scheduler. Reboot.
2) Zenx as governor, min. 200 max 800, Sioplus scheduler. Reboot.
After the first, the second or the third reboot, some of these values you've set will change spontaneously on their own.
UPDATE 2: I've got a screen flicker issue while I was browsing in Naked Browser with the new LCDCLK frequency.
Tried to set echo 1 > /sys/kernel/mcde/lcdclk, it's ok now, but I've noticed that this value is not kept after a reboot.
Do you need a specific log?
In case please write me any command and I'll give you the output.

I suggest to keep it unchecked, otherwise it'll change the profile randomly, and that's probably not what u want.

There's still no fix ! But what i did is to add the perf. profile in my control app ... that works fully independently.
But that's probably not what u guys want.
My last try was to do that over build.prop .. this works only for around 15 seconds (after wiping dalvik cache it's around 30 sec.) and then it sets back to "balanced" .. so i use it anyway just for speeding up the boot sequence:
Code:
# CM Performance Profiles (only during boot)
# 0= powersave; 1= balanced; 2= performance - default
sys.perf.profile=2
IMO the best way is to add the perf. profiles button to the quick settings, then it's very easy to switch between the 3 profiles.
Using the same profile for everything is for sure not the best option if u want performance + powersave at the same time.
Personally i use performance, and when i read an pdf or watch a YouTube Video then i switch to powersave.
Using powersave or even balanced for normal usage isn't recommended as it can drain even more battery than using performance, because it's slower and the CPU will stay too long on max. freq and the LCD also will stay longer ON, which leads both to increase power consumption.
So the faster the cpu is, the quicker it'll go on idle (min cpu 200) which is powersaving freq and the faster u'll turn OFF the screen, and logical bigger time on suspend --> deep sleep :highfive:

Sorry for so late response, I had to take a break in a development because suddenly got sick with a flu (I'm fine now, btw) :silly:
I think I've found a temporary solution to this bug, take a look if you're interested:
https://github.com/ChronoMonochrome...mmit/bd0dcce403633543f1bf11e5f8b476a3e88322cb
New build is up!
Changelog
R4.6.2
rebased to CM14.1 branch (added support for 6.0.1 and 7.1.2 ROMs) *
Hey there! I've been testing 6.0.1 / 7.1.2 ROMs and I've recently got some issues with camera on 3.4.x kernel build, so I've decided to release a new refresh build (based on 3.0.101 sources).
I've rebased the most of recent changes to CM14.1 branch in order to support these ROMs (so if you're using older ROMs like stock 4.1.2 then better to use previous release cause some patches might be missing here).

Help regarding Franco Kernel Manager?

Just downloaded the latest version of franco kernel manager 6.1. Im a total noob in terms of using this tool, so I've been looking for a guide or a tutorial that can assist in using it. Also what is the method of flashing the franco kernel from this tool? Where can I download the franco kernel.zip? I have been looking all over, cant seem to find it. Plz help
Im currently on RR Rom latest version 8.6.3. Im looking for a setting to enhance battery life and overall performance of the Phone.

Hey there
What I did to get Franco kernel was flash it during my first time rooting (so it was a clean flash, as the phone had be factory reset). Once you're in TWRP, you flash Franco kernel and then magisk. This is one way to do it. I can't advise you to flash a new kernel without clean flash because I personally didn't do it and I don't know if issues will come from that. If you can do it, my personal advice is to just do a clean flash. You know the drill, wipe system data and that stuff > flash ROM > Kernel > Magisk, and done
As for where you can get the zip, there is a thread here in the OP5 XDA forum on ROMs and Kernels I think and that's where franco posted the kernels. He's got a website too linked in the same post
HOWEVER, he hasn't updated them since last year, and I don't think they have support for Android 10, only 9
As for settings, well, in my own experience, you won't get any noticeable boost in battery life or performance without doing some drastic change.
If you want better battery life, you can decrease the maximum CPU frequency, change the governor to Conservative or Powersave, disable some cores, or all of those at once, but they WILL degrade performance, sometimes you won't notice but then you'll try to load a heavy webpage on Chrome and then you'll REALLY notice it.
The inverse is also true. To increase performance you change the governor to performance; usually the CPU frequency is set to its maximum by default, and the cores are all enabled anyway so you don't have to change anything. BUT, keeping the governor in Performance will also keep the CPU clocks at its maximum, and that's going to drain your battery like CRAZY, plus it'll overheat it. Usually there is no practical need for this setting, but I use it to play games on Dolphin emulator since thats when I can actually make use of that performance.
A better alternative is to keep the governor on Interactive, which will scale up CPU clocks depending on the load (if doing light stuff, low clocks. Heavy stuff > high clocks). Otherwise, Conservative does the same thing but takes longer to use higher clocks, so battery is saved.
Always use 1 governor for all cores. Do NOT use multiple governors (example: powersave for big cores, performance for little cores) because that will cause instability issues
Also, if you make any changes, you gotta tap the toggle on it, which will say something like "stay on boot: true". Otherwise, if you for instance change your governor to Performance, and then reboot, all your changes will reset to Default
Personally I just keep my governor in Conservative and roll with the defaults.
Hope that helps ya
sorry for digging but I was loooking for solution..
just make a backup of present kernel (tuned with FKM) and then flash it from backup menu
I was trying flash with twrp, magisk, 'set on boot' at first and many other things but it was so simple, it's there all the time
