Thanks for your reply. My first ICS stock ROMs had no disconnect issues at all such as the xxalf2 ( no router or phone adjustments). The more recent ICS and jb updates have the WiFi keep connecting and reconnecting. What's odd is that the first ROM/ kernel were fine. Wondering if you can spot a difference in the xxalf2 and the more recent versions. Many thanks.

My WiFi is basically unusable as it disconnects so often
[Galaxy S III Android Development] eric-filth:
Your welcome, i said some things about this version in PM.

And now im testing battery.

[Galaxy S III Android Development] harunjo:
so you got the wifi problem since ICS ?

i m afraid you get a defect wifi module in your s3 hardware....

as far i know xxalf2 is an ICS rom

how if you revert back to xxalf2 rom? is your wifi will be ok again afterwards?
[Galaxy S III Android Development] orangestrawberry:
Yeah could be. I was just surprised that it worked fine and then stopped working after more recent updates. Probably broke it doing extreme tethering!

Does this mean we can now use scripts to control GPU frequency and voltage? :)

yes..but gpu voltage only, you can not OC the gpu freq,..please report if you had problem with that.

Hi, thanks for the update v2 b1 was awsome i had screen on for 6 and half hours :) just wondering how do you used script to undervolt GPU?

any instruction for noob? :(

Thanks

EDIT: Also how do i check GPU voltage? i have just tried create txt file in init.d folder name V0Gpu and

#!/system/bin/sh

echo 160 750 > /sys/devices/system/gpu/volt_table

echo 266 800 > /sys/devices/system/gpu/volt_table

echo 350 850 > /sys/devices/system/gpu/volt_table

echo 440 900 > /sys/devices/system/gpu/volt_table

set permission to 777 will it work? how do i check if it worked? Thanks :)

GPU undervolting patterns

light: 875 900 950 1000 (this is galaxsih kernel default GPU UnderVolt)

medium: 850 875 925 975

heavy: 825 850 900 925

note: this kernel already have GPU UV light setting (-25mV) by default

example init.d script for medium (-50mv) GPU UV:

in terminal (or using root explorer) create a file, put the file inside of /system/etc/init.d/

the file name must have 11xxx file name format to be working

for example:

1. # touch /system/etc/init.d/11gpuUV

2. open the file using root exlorer and edit the empty 11gpuUV file like below

#!/system/bin/sh
echo "850000 875000 925000 975000" > /sys/class/misc/gpu_voltage_control/gpu_control

3. change the file permission

# chmod 777 /system/etc/init.d/11gpuUV

4. reboot

5. recheck /sys/class/misc/gpu_voltage_control/gpu_control again to confirm the UV value commit;

- for troubleshoot init.d process you can read post init process at /data/user.log after reboot
[Galaxy S III Android Development] spencer1208:
I am on 2.0b2 now and using Voltage Control Extreme.

Under device info in VC there are only 3 CPUs (0,1,3).

Also there is only SIO now not deadline anymore.

Is it possible to use VC to UV GPU?

Currently VC does not offer any GPU options at all.

I believe this is due to "EE" Orange-T-Mobile doing upgrades to their network. I had a friend whos HTC lost data for about 1 hour this morning, so doubt its Kernel related.

As for V2 B2, working very nice dude, Silky smooth and battery run time appears to be much better, sleeps well and ZERO lag oberved.

i also got bad battery with v2.0 beta2...last night..my cpu stat never sleep, it always stays at 200 MHZ...after checking..my wifi router is had lost connection internet connection,,,thats why my phone is always woke up..

that was because always online application like whatsapp and gmail is tried to ping the connection to router gateway

[Galaxy S III Android Development] drdoulittle:
@harunjo

:D Hi so fast the updates do not bring then v2.0 beta1 ran really well, no problems and now already v2.0beta2 one can see the differences not or what one can tune perhaps even better. In addition one really needs 3-4 days around Before and disadvantages to recognise, because the Kernel is also important for the Modem.

So better a little bit more time with the updates leaves you and gets to you the communications as a solution from the Posts of the users here.

Has also installed v2.0beta2 of course and now I must compare, up to now, however, all top, as usual, just!:cool:

Thanks Mate very nice Work and top Quality.!!

Im not sure why but with beta2 my battery drain a bit higher than v1.3beta4..unplugging from 100% and using it for a few minutes it dropped by 7% then i switched back to v1.3beta4...been using it for nearly 45minutes straight...dropped 5% only. Im on full hsdpa. I barely use wifi as its a lot slower connection on my side:p good job om harunjo :D

edit: i meant v.2 beta2 with the battery drain
[Galaxy S III Android Development] harunjo:
still not release yet..find my github for change log

so far with beta3 added more hardcore tweak and disabling kernel debug.

I think we all should spend more time testing each build as it take some time for kernel to settle etc. So we can give better feedback. Also by doing this, harunjo can spend more time on testing new build. b2 was released yesterday so people facing problem with b2 should wipe cache and dalvik then try the kernel for longer time. i also had problem at first with checkrom v6 so i wiped cache / dalvik, let the phone settle for an hour then tested battery and its awsome. no issues at all. :good:

Hi all, my first post in this thread ... Many thanks for this excellent kernel!

Harunjo, I have a problem with the 2.0 B2.

I have configured to use the maximum frequency up to 800MHz and the beta 1 had no drawbacks, beta2 now every time I start an application uses as standard 1400.

Solution for beta 3?

that there is possibility to use and configure 2 parametters DEAD LINE and SIO separately in Scheduler?

Thank you!
[Galaxy S III Android Development] harunjo:
thanks for your report...

why this kernel need to include 2 io scheduler? do you have any reason for that?

Just let it stabilize the Phone and do the following.

* Open Voltage Control

* reset the frequency values

* I closed the application

* I returned to run the application and had worked there at 1400 MHZ

Beta2 situation that did not happen before ... CONFUSED

Enviado desde mi GT-I9300 usando Tapatalk 2
[Galaxy S III Android Development] harunjo:
thats seem normal for me..your 800mhz setting is working..

application like voltage control and setcpu work after android boot..

when android boot it will use highest cpu freq..until voltage control setting take effect.

see below...jelly bean rom takes almost 1 min to boot.

please try for about 2 - 3 hours and take screen capture again..

or you can change your app to setcpu version..if you got different result then maybe voltage control is not compatibel with jelly bean rom
[Galaxy S III Android Development] rodrigo_said:
Thanks for the clarification, so let q clear that the system stabilizes after the start ... Maybe it's me ... but do the test with beta 1 and does not happen : Crying: Even now after 10 minutes of system boot with beta 2 still working to start the apk to 1400-1100-800 on that scale ...

Each phone is a world! : P waiting for beta 3 : Victoria:

Saludos!

P/D: My request schedulers can configure two SIO and DEAD LINE was because I thought my problem was coming from that side to have changed the default trigger that had beta 1 and if DEAD LINE. :D
[Galaxy S III Android Development] harunjo:
i dont think so, my tweak related to below behaviour is been revert to stock kernel..

i have patch for that...i removed it from beta2 because that patch make power saving feature is not working..andreilux did fix that, i will try to put andreilux patch and will see the different.

and that not because sio scheduller mistake...poor SIO...lol

SIO I found to be brilliant on JB. Performance is noticably different.

Had a strange error with "SecPhone", it was awake for 4 hours! 22% drop over 7 Hours. It only became present after 2 hours after I took it off charge. Never had this before BETA2.

Harunjo, when will you be releasing BETA3? :p lol
[Galaxy S III Android Development] fastcx:
previous experience with siyah kernel,n my old galaxy tab 7,was that after a long period of time,e.g. a day of usage without restarting phone, there will be slow down on any task that required data read write. Most noticeable is usage of maps,scroll around with data loading with or without traffic layer. Laggy experience compares to cfq n deadline.

Just my previous experience, currently need more time to test, as usual. With noticeable lag in maps scrolling while data is still loading in new area.

The Kernel v2.0b2 is very good.

v2.0b1 is as good in the accumulator as v2.0b2. However, the performance and quickness is only minimum a little better with v2.0b1. So with the GalaXsih Kernel we are on the right overtaking lane and no problems with externally 16 GB, 32 GB. Everything functions perfectly today could test sometimes a little bit more and use a lot the phone and no FC, Lags, Reboots or even Wifi, Data, Sync problems. Logging in and logging off in the Telekom-Hotspot without problems. The Kernel GalaXsih v2.0b2 is already like 1.2, 1.3 and b1 a good throw and am very contented and tests with pleasure because everything goes.

300 Mhz > 800mV

400 Mhz > 825mV

500 Mhz > 850mV

600 Mhz > 875mV

1100 Mhz > 1025mV

1200 Mhz > 1075mV

1300 Mhz > 1125mV

1400 Mhz > 1175mV

If u want to play it safe, try to lower the voltages by -75mV first and test for stability (add +25mV to my voltages)
