When it is isnt charging,did it reboot when a call came?

EDIT:

It showed you Kernel Panic??

Try v3.9beta. :)

I used Sourcery G++ Lite to build v3.9beta.

If it happends again,please report.
[Galaxy S Advance I9070 Android Development] migaia:
No, only when it's charging.

I would like try 3.9 but I'm not able to use terminal emulator.

[Galaxy S Advance I9070 Android Development] ming86:
My phone have the problem..tried on 3.9beta and 3.8.6rc.

Stock ROM.

Charging:

unplug charger:
[Galaxy S Advance I9070 Android Development] shut_down:
Put some other governor, and get it back to prgasusQ. With this.

P.S. I didn't see that it was only when charging. :)
[Galaxy S Advance I9070 Android Development] cocafe:
Thanks.

And it shows you kernel panic?

I will try it tomorrow. :)

Try to use other governors,and check whether this issue happends or not.

Make sure that your cpu havent been controlled by some other apps.

I will test it when i charge tomorrow. :)
[Galaxy S Advance I9070 Android Development] cocafe:
Cpu rendering is software rendering, it makes UI lag sometimes, so disable it. :)

Audio is built-in in kernel.

Optional scripts are my tweak, if you want to use, put them in init.d folder with execution permission.Or they wont be enabled.
[Galaxy S Advance I9070 Android Development] petraru1:
cocafe what I/O planificator you recommend ?

i read the facts for I/O planificator and from the results of the benchmarks i`ve notice that SIO and noop are the best but i want your opinion :D
[Galaxy S Advance I9070 Android Development] cocafe:
Usually, i use SIO.

For camera and copying files( heavy io load ), i use BFQ. :D

BTW, you can tweak the schedulers in /sys/block/mmcblk0/queue/iosched/ for best performance. :D
[Galaxy S Advance I9070 Android Development] hafidzduddin:
thanks

I'll try it tonight :fingers-crossed::fingers-crossed:

report ------

from now, custom bootanim work . cannot loop again

could i use your optional script to my kernel?

in your mali tweak. why you set job run time 5000. in the normal setting it at 900000
[Galaxy S Advance I9070 Android Development] cocafe:
Yeh, you can have a try. :D

Jobtime is not my tweak. :D

I got this mali tweak from somewhere.

And the l2 cache reads tweak doesnt work via init.d , just increase it in kernel source.
[Galaxy S Advance I9070 Android Development] hafidzduddin:
thank you.

i will try to change l2 cache in kernel source :D:D
[Galaxy S Advance I9070 Android Development] petraru1:
can you explain a little more ? i found a tutorial here on xda, but i really don`t understand :)
[Galaxy S Advance I9070 Android Development] cocafe:
Well, i think i cant't explain more clearly than the tutorials makers. :)

Read more, and you will get it. :p
[Galaxy S Advance I9070 Android Development] petraru1:
i was reffering to this :)
[Galaxy S Advance I9070 Android Development] cocafe:
As far as i know, there are some apps can tweak them. (e.g. ROM Toolbox Pro) :)

You can tweak them via scripts, too.

And the effects of these values, Google can tell you. :D
[Galaxy S Advance I9070 Android Development] sese306:
And if job run time is set to 5000 which are the effects? Does job run time means that after 5000 seconds or miliseconds or something, GPU will drop that task? Or what does it mean? Is it better to have job run time >900000 or <900000 (eg. 5000)?
[Galaxy S Advance I9070 Android Development] petraru1:
tnx for your patience, now i know what to look for
[Galaxy S Advance I9070 Android Development] cocafe:
Yeh, i think so, but not seconds.The source code says, it is ms. :p

5000 is the default value in source code.You can set it bigger than 900000, and have a look.

I have set it 9999999 before, but it seems taking no effects. :(
[Galaxy S Advance I9070 Android Development] RSDamasceno:
Working fine, on JetMod.

Thanks!

I wanted to make a request: include in its kernel the ability to record calls in two ways, PLEASE!

Can you boot into recovery?

I can't boot into recovery using volume up+home+power. if I hold it too long it just turns off but if I hold it till samsung logo it just boots normally
[Galaxy S Advance I9070 Android Development] shut_down:
On my phone boots into recovery normaly with up+home+power. I had JetMod installed before using this kernel.
[Galaxy S Advance I9070 Android Development] darrie1:
Hmmm... I tried reboot recovery and it still didnt boot into recovery

Edit: i thought if i did that i would be able to boot into recovery but i reas it wrong in OP

Edit: reinstalled the kernel and the problem persist
[Galaxy S Advance I9070 Android Development] cocafe:
Yeh, i have met the problem before.

But after flashing the kernel which has TWRP, it never happens again.

I know a method.

Power off, Connect your phone to computer with USB cable, and press keys immediately, when the screen goes black, press the keys again, it should boot and enter recovery.
[Galaxy S Advance I9070 Android Development] cocafe:
Well, i will try when i am free.:p

Working on cpuidle module now.
[Galaxy S Advance I9070 Android Development] anggriawan:
help me please :(

i have problem on my SGSA GT-i9070,, my fps has drooped stuck on 30fps (using app fps tester)

if i test using antutu benchmark the result is 35fps

then i read this thread, and someone (petaru1) have a same problem with me,,

so, my question is:

can i fix problem fps drop when i using this kernel?

3 days ago I installed a kernel twrp by diego for make a back up stock rom,, if it's okay if I install this kernel on original stock rom?

i'm very newbie for using android :(

Sorry but I don't know what kernel panico is.

[Galaxy S Advance I9070 Android Development] cocafe:
Eek!!

That is:

When phone reboots,and it shows you an Android with "Kernel Panic Upload Mode"

@shut_down

Could you help me check that charging issue? :)

Or in other words,do you find that issue on your phone? :confused:

I cannot find any code about charging in PegasusQ source code.

Gotta sleep. :p
[Galaxy S Advance I9070 Android Development] shut_down:
I was on ondemand/sio. And I had no problem with cpu, it was around 200MHz while charging. I was doing something with phone when it was charging. Now it is 100%, I will change to pegasysQ and see what happend when I charge next time. ;)

P.S. migaia do you use some battery save app? Maybe it trigger CPU while charging.
[Galaxy S Advance I9070 Android Development] ming86:
yes, I'm using No-frills CPU Control.

same result.

tried OnDemand, Interactive, InteractiveX Governor, are able to keep 200MHz most of the time in charging mode (screen off).

but pegasysQ trend upscale to maximum freq (1000MHz, 800MHz). (screen off)..
[Galaxy S Advance I9070 Android Development] Noobpening:
cocafe, do i need to install cocore kernel from v3.0 to 3.8.6 or just install 3.8.6?

** sory for noob question
[Galaxy S Advance I9070 Android Development] shut_down:
Just 3.8.6.

---------- Post added at 04:58 PM ---------- Previous post was at 04:57 PM ----------

I will try with pegasysQ . My phone is full now. ;)
[Galaxy S Advance I9070 Android Development] migaia:
No kernel panic showed when the phone restart.

The issue is out when I'm usb connected. I've to verify if it happening whit wall charger too.

[Galaxy S Advance I9070 Android Development] migaia:
Maybe another issue. Setting governor on pegasusq and I/o on sio, my phone reboot from one to several times before to start working fine. All alone. Whit ondemand and sio instead, it boot fine.

[Galaxy S Advance I9070 Android Development] Sami Kabir:
Sorry to ask this noob question but are all these problems I read above related with only CoCore v3.8.6 or is it related with all of the versions of CoCore?
[Galaxy S Advance I9070 Android Development] cocafe:
My phone works well.

PegasusQ+SIO+Charging

Make sure that you cpu hasnt been controlled by some battery saving apps.

I am waiting for the reports from shut_down :)
[Galaxy S Advance I9070 Android Development] Sami Kabir:
When is v3.9 coming and can you please answer my previous question:
[Galaxy S Advance I9070 Android Development] cocafe:
Lol.

The update date?

It depends on my progress.

I am busy with study these day.

Work slowly now.

Mysterious Downloading?

That is a real noob question.

I dont mean to be rude.

It is only a kernel,it dont contain any app.

Although i can install apps via scripts,why do i do that stupid thing?

(That is method we root devices via kernels.)

Absolutely,I wont put any shell scripts to install any apps which will download anything automatically.

Dont forget this,i am using the kernel made by myself. :)

Charging issue?

You mean the freqs?

I dont have this issue.

I am testing the call issues when charging.

It perhaps caused by Linaro Toolchain.
[Galaxy S Advance I9070 Android Development] Javho:
o flash the kernel on a stock rom need to change something? or is it just flash
[Galaxy S Advance I9070 Android Development] cocafe:
Just flash. :)

No wipes.

And no reboots when it is charging and a call comes. :)
[Galaxy S Advance I9070 Android Development] naitik2012:
i just scored 7402 in antutu wid ondemand and sio so i prefer ondemand wat u think is it good ?

[Galaxy S Advance I9070 Android Development] shut_down:

Hi Cocafe - want thanks again for your teaching install CoCore Kernel v3.8.6rc... After install for gaming seem improve but some of part still will lang & hang abit but i just use "ondemand" mode only... :p see my photos attached... how to make it more smooth that i run "Modern Combat 3" game... ??
[Galaxy S Advance I9070 Android Development] migaia:
So, I' deflagged usb debug and all seems work fine now.

I was connected via USB to PC and had incoming call and phone after 10 second reboot. Then I saw that phone was not connected with PC and so I deflagged it. Now no more strange reboot. Just for a while :D

Offtopic: Why are you guys using apps for screenshots? You can use home + power key!

Ontopic: How can you get such high deepsleep?
[Galaxy S Advance I9070 Android Development] shut_down:
DeepSleep Mode:

* Default mode is State4, i changed it to State5. Increased standby life time.

* Deepest mode is State6, but it makes phone unstable.

* You can get information about CPU sleep states:

Code:

cat /d/cpuidle/stats

* To change the allowed deepest sleep mode: (e.g. Allow State6)

Code:

#echo 6 > /d/cpuidle/deepest_state

Use terminal emulator on phone. :)
[Galaxy S Advance I9070 Android Development] cocafe:
Hmm?

Eek...

I was considering that reboots are caused by Linaro Toolchains. :)

It seems that i am wrong.

In fact,i got some reboots(Kernel Panic) when i connect it to computer.(Used Stock Kernel) :p

Hmm.

How about using some sysctl.conf tweaks? :p

I will update my sysctl.conf today,if it is convenient :)

Today i can continue my works.
[Galaxy S Advance I9070 Android Development] coolkillermax:
Such a Good news that you will update it :o & hope this sysctl.conf can include in latest CoCore Kernel v3.9 so we just easy flash in TWRP to enjoy it :silly: But take your time Cocafe no need rush & good update need more time... ;) :) :o

Also my games problem improve alot after install "Chainfire3D Pro" http://xdaforums.com/showthread.php?t=1087427

Jetmod Default recovery & Rebooter can't go in TWRP

Hi Cocafe,

After install your CoCore Kernel v3.8.6rc found 1 issue :

i can't use Jetmod Default recovery & Rebooter go in TWRP it's just normal reboot only :( (before with Varun Jetmod kernel can) ..... i must use "Volume up+Home+power button" to go in...:rolleyes: May be this is Bug or Kernel don't so suit for Jetmod ?? How to solve it ??
[Galaxy S Advance I9070 Android Development] petraru1:
read the first page and you will find the answer
[Galaxy S Advance I9070 Android Development] coolkillermax:
Yes i have read it before ask this question BUT i using Method 2 install Cocore ( Use this method in order to avoid triggering J4FS BUG. ) that it said can avoid this J4FS Bug but still don't work ?? so i confused ... :confused: ?
[Galaxy S Advance I9070 Android Development] cocafe:
Today i am about to fix this.

So hope i can work out this. :)

EDIT:

And about Chainfire3D:

This app will replace libGLESv1_CM.so and libGLESv2.so in /system/lib.

That will make your phone use software rendering(That is how it emulates other gpus).

Perhaps your game is incompatible with our Mali GPU,you can use other GPUs to cheat them.

And paste the code,save it.

You can tweak some parameters of Mali in /sys/module/mali/parameters

sysctl.conf is in /system/etc/

Nope.I havent met this issue with the kernel i am using now.:)

Nope.

Well.

It is incompatible with i9070p.

This kernel causes high cpu load.

I should put some notifications on main post.

Wait for the kernel from my teammate CallMeVentus.

He is working on i9070p kernel.

And,Relax,guys,this is *BETA* version.

What does BETA mean?

It means it havent been tested fully.

I will optimize it in release version. :)

Previously I had some problems like freezes, audio issues (The speakers sometimes went crazy, for example: sms notification volume ok, facebook notification higher volume without reason.

Now these problems are gone and I really appreciate that now I can reboot in recovery mode without turn off the phone :D thank you for your work!!

Put this file in /system/etc/init.d/ (I just created it, you can check what is there buy opening it in text editor). And in some root explorer (like Solid Explorer) open properties of that file and check all permissions. It will enable that sysctl on boot.
