Hannspad: no Governors and schedulers available in Setcpu - G Tablet Q&A, Help & Troubleshooting

Hello everybody.
I have a Hannspree Hannspad, which is similar to the G Tab.
Currently I am Using Flashback 10 with a kernel provided by fards and edited by me.
Here on Github:
https://github.com/Gott/ab73kernel-Hannspad-2632
Unfortunately, I cannot set the CPU Governors in apps as SetCPU, Antutu Cpu Master, or else.
The fields for setting the governors are just blank.
When I check the files in /sys/dev/system/cpu/cpu0/cpufreq/scaling_governor
there is no file.
there is a /sys/dev/ but nothing else.
Can you tell me what is wrong?
I set the Governor in the kernel config, as well as the scheduler (noop).
Furthermore, the Interactive and Conservative Governor do not work.
The tablet simply does not start.
It hangs on the Hannspree logo, before the Flashback logo (Framebuffer dummy driver).

That kernel looks like a pershoot-derived kernel which has the ondemand governor compiled in as the default; and, you don't need to change it which is why the /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors file will read blank.

That's the wrong directory. It's actually: /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

Thanks.
Do you know if the Interactive or Conservative are working in the pershoot kernel?
If compiled, my tablet is not starting any more.
I thought about implementing another governor, as I think, ondemand clocks up too fast.

How did you enable those governors? By editing the defconfig file manually or using make config/menuconfig/xconfig?

Not sure if it'll do what you want. See this question and pershoot's answer in the next one.

I stayed with smartass2 for a while now on MIUI and Wildmonks Kernel. This kernel lacks that smartass2 govenor, so i am using the tweaked ondemand one. I must say it is smoother and i didn't have any issues so far. Battery drain is ABOUT the same - cannot really give any definite opinions cuz i used it for only hours now.
But i'll report back. Try the ondemand one - its good so far.
How install it? Should i put the zip on the SD card and install it in the bootloader?

This seems to break my wifi. After flashing, everything seems okay but wifi just says 'error' when I try to turn it on. Anyone else have this?
I am on CM7 newest nightly
Come to think about it, ever since I flashed one of his previous builds, every time I try to flash a diff kernel I get this problem. Think I had this problem with one of IR's kernels...

What Kernels for No-Frills CPU?

My SGA is on GB 2.3.6 (Russian ROM) and I have installed No-Frills CPU, but I am not able to use it to full potential. The Developer says I need some custom Kernels for this.
Which Kernels are these? Is it ok to use diff kernels?
what do u mean by "full potential"?
afaik for changing cpu scaling freq, cpu governor or changing disk io scheduler, u can do it even on stock kernel. maybe the selection is a little bit less, but it'll definitely works.
i dont know if cpufrills can also change cpu voltage, even so we dont have any kernel that support cpu voltage changing yet.
You might have seen No-Frills cpu, but few users are getting more governors than me using some diff kernel.
anyways, I want some other way, so that my cpu cuts down frequency really down when phone is locked, and jump up accoring to requirement. (Just like Cool'n quiet in AMD)
then u might wanna install cfroot kernel. it contain smartassv2 and interactiveX that do have automatic cpu down scaling when screen off.
but u can also set up profile to do it manually on other governors using setcpu.
What about the kernel by squadzone supposedly optimised for gingercruzt but it works for cm7 and has 6 IO schedulers, but cf-root is best for stock

My phone is already rooted and got busybox. So if I use cfroot, what would the affect on previous root and busybox? How do I backup current kernel if I need to go back.

no, it wont affect root as it also give root.
and just use clockworkmod recovery to create backup of ur whole rom. and if u just wanna restore kernel use the advance restore to restore just the kernel itself

Hey, I'm using ICS Final and I only have the InteractiveX and normal Interactive options but not the smartassV2. Where can I get it? I'm using the Smartass governor out of all of them. What is the difference between the two? (V1 & V2)

[Kernel][New Release]GoldenKernel[v2]

Hi guys....i'm an experienced developer who ported CM9 on lg P500......today i have a Galaxy SIII Mini and i want to start to develop for this device. Meanwhile i'm helping oliver for cm10, i want to develop a custom kernel. The objective is to have good battery life and great perfomances.
Changelog for v2:
MultiCore Sched Support
JRCU (an RCU optimized for multicore devices)
Optimized Arm RWSem Algorithm
Autogroup Sched
LowmemoryKiller updated to latest version and enabled an option that calculates automatically oom values
Added some Mali patches (thanks to cocafe)
SLQB memory allocator
Row I/O Scheduler default
JIT compiler for net packages
CleanCache
A lots of new Governors
A lots of patches that you can find here: https://github.com/lupohirp/GoldenKernel/commits/master
BUG!!!!! : Reboot option doesn't work. Must fix this in samsung drivers!
Here's changelog for v1:
Kernel compiled with linaro gcc 4.7.3
Added hotplug and pegasusq governor
Cpu unaligned specified path
Dynamic fsync control
Here's the download link(V2):https://hotfile.com/dl/202694028/d947bb6/goldenkernelv2.zip.html
Kernel Sources Here: https://github.com/lupohirp/GoldenKernel
Change Governor with setcpu or nofrills. I reccomend to use OnDemandQ governor for this reason: OnDemandQ disable the second core when is not needed and reactivate it when cpu load is heavy. the result is a great perfomance with a a really good battery drain
For install this FLASH WITH RECOVERY!!!

thx a lot for your work, have installed, there is one problem i can see at once, i can not set cpu freq above 800, when you set to 1000 it´s changes to 800
Edit: forget about 800, i did not understood power saving mode , but governor choice does not persist reboot
Installed and setCPU governor to hotplug and I will see how it goes.
Is it possible to have also stock CWR kernel , just in case...?

Make sure you don't have cpu power saving mode on in powersaving settings. Otherwise you'll get max 800.

If your signature is correct you have the -N version S3 mini would you try to switch NFC on after flashing the kernel? if it works it means he used the right configuration file when compiling and the kernel is universal for all the I8190 variants Thank you very much!

o3 Compile optimizations
Knock-on enabled through app in second post
Fastcharge added as option - enable using Trickstermod
Row, Sio, Fiops, and Zen IO Schedulers added - trickstermod to change
Sound Control using TricksterMod
LCD Screen Control using TricksterMod
Fsync On/Off using Trickstermod (off as default)
User Space Voltage Control - TricksterMod or my 88sleektweaks init.d script to change.
Exfat support (2-4-15 and later CyanogenMod version)
Lots of optimizations with more to come!
The kernel source and Commits that show all changes for this kernel can be found here:GITHUB
Prerequisites
Unlocked bootloader
Root
Install Busybox for init.d support
TricksterMod is recommended for changing settings
How does this work?
Start by making a Backup of your boot in recovery, then:
Flash the latest version in Recovery . Proceed to the downloads below, download to your tablet, reboot into recovery and install the zip --That simple!
if you want to build your own kernel start to finish with complete instructions, you can follow my guide for rolling your own kernel HERE
Please hit "Thanks" to show your support!

Knock-on app for my kernel can be downloaded here.
To add my sleektweeks init.d file, and/or the Zipalign file, see my post: HERE
Updated -SleekCyan2 - to include exfat support, LCD screen control, and further optimizations for GPU and the linaro toolchain.
Updated - SleekCyan3 - to include knock-on by default, removal of some debugging, quicker deep sleep. (better battery?)

Exfat support for sdcards now works out of the box with CyanogenMod version 2-4-15 and later.
So I flashed this last night when I saw you posted it recently and this morning I checked it and it had zero battery drain overnight, very nice. Can't wait to dig in a little deeper when I get time. Between this and the new CM12, 2015 is really shaping up to be a good year for the old (but great) v510, finally, thank you.

Yep! The latest 88sleektweaks has voltage control table as well ( already adjusted down a bit to the settings I use). These can be changed here but be careful! TricksterMod is useful for making the initial changes to test as they won't get restored on boot. If you change them in the file and something goes wrong, you will have to remove the file using twrp.

Just tried it with CM12 and it's a super V510 combo! Feels fast and smooth! Thanks for your XDA development & contribution.
UPDATED 2-12-15
Added Row IO Scheduler and Sound control - Change using trickster or in settings for row, and in trickster for sound control. Also added upstream fixes.
Is Row better than cfq? I think maybe it is . . . Battery will be the deciding factor for me. If anybody wants Row default for this kernel, let me know and I will implement it on next version. Regards,
I'll give it a go tomorrow, currently I've tweeked to Ondemand and ReadAhead to 512. Cool

Are you finding On-demand better than Interactive? Seems like interactive is smoother to me. Also, keep in mind that the larger the read ahead the more battery is used.

Not much difference maybe slightly faster but still analyzing with the new rom update...
BTW, did you see my post cm12 rom about GPS? Maybe you can take a look...
Row is working very good & smooth so far (speed, smooth & stable are my priorities and then battery). Think I'll stay with it; up to you if u want it as default.
