Have you guys tired enabling force 2d rendering in development options?
[Galaxy S III Original Android Development] onurerler:
Yes, but it doesnt effect scrolling lags.
[Galaxy S III Original Android Development] hamma:
No such problems here.
[Galaxy S III Original Android Development] onurerler:
which rom are you using ???
[Galaxy S III Original Android Development] hamma:
Revolution HD
[Galaxy S III Original Android Development] GrimPivo:
Should I enable "disable hardware overlays" too?
[Galaxy S III Original Android Development] cink40:
No lag whatsoever, (and without forced 2d gpu rendering), (insertcoin rom+perseus default config)
[Galaxy S III Original Android Development] mariosraptor:
No lags, no freezes, no 2d rendering. Super smooth wanamlite 3.7. Great battery life. 5hours screen on time wifi+data+sync+dropbox upload.

So if someone has issues i am sure it is his fault not kernels.

Should give also more info. Uv cpu gpu, rom etc before making any accusations.

Cheers
[Galaxy S III Original Android Development] nfsmw_gr:
The only problem i had so far was a few major lockups for around 10-15 seconds while browsing on chrome with 8-10 tabs open excactly the same like on siyah...

I'm starting to think that these lockups aint the kernel's fault but the pre-release "official" firmaware's fault or just a chrome problem because with other apps i dont have any issue...

Anyone can confirm?
[Galaxy S III Original Android Development] GrimPivo:
Well, I'm just flash Perseus 24.2, and it seems to me visible more laggy than stock kernel on homescreens and lists scrolling, and on open folders with more than 6 icons inside.

Omega 27.2 ROM. Force GPU enabled.

Please don't kill me :D
[Galaxy S III Original Android Development] mariosraptor:
Just let it settle and disable 2d rendering.

Can't see any + from it
[Galaxy S III Original Android Development] Anakha56:
Donation done! Although it was through the PayPal mobile app so not sure if it went through :P.
[Galaxy S III Original Android Development] onurerler:
All versions of Perseus (JB vers.) was laggy on scrolling not only 24.2.

As i said i think this problem kernel releated (governor type or governor tweaks, mali driver or hwcomposer. possible source of problem).

For example: If i set cpu governor to performance than lags gone but cpu constantly running at 1400mhz. But if i set governor to pegasusq than scrolling is laggy. If i use siyah kernel or kernel which is come with revolution hd than no lag problem at all on scrolling. but freezing problems.
[Galaxy S III Original Android Development] amirsardari:
+1

as i said this kernel cause lag for me especialy when i go to sub menu of setting and then hit return it show a laggy transition animation and sometimes in appdrawer . i use revolution hd and no 2d rendering option . now i restore stock revolution hd kernel and its smooth again
[Galaxy S III Original Android Development] sebarkh:
Tonight I have seen the phone has frozen twice and I have missed alarms for work so I overslept because of the kernel.

I noticed this using better battery widget. It has missing readings for these two periods of time.
[Galaxy S III Original Android Development] mariosraptor:
Revolution hd i think has 2d rendering hardocoded in the rom. Ne need for it to be enabled in dev settings. In if everyone that have lag are using revolution hd. Then you answered yourself. The problem is the rom not the kernel.

You can try to wipe start clean.

Flash revolution hd and emmediatly flash the kernel and then reboot.

Submit your feedback.
[Galaxy S III Original Android Development] Yank555:
I suppose you're referring to :

video.accelerate.hw=1

Not to be found in ARHD 11.x build.prop.

JP.
[Galaxy S III Original Android Development] mariosraptor:
To this

Removed software (CPU) rendering -*full*Exynos 4 Quad (GPU) rendering
[Galaxy S III Original Android Development] Yank555:
Hehe, ok, one point goes to you, instead of just reading ARHD's OP, I ran looking into the zip file :D

I'm not sure if that's not just a copy paste thing, since I thought that forced 2d GPU was actually activated by "video.accelerate.hw=1" ...

I'll ask mike what he means when he states "Removed software (CPU) rendering -*full*Exynos 4 Quad (GPU) rendering".

So we get to the bottom of that story ;)

JP.

EDIT : Question asked in ARHD thread.
[Galaxy S III Original Android Development] EViollet:
Have you undervolted the CPU?

I suggest you look at your apps/setup. Either you have misconfigured something or you have a hardware problem. If the kernel had freezing issues, I guess the thread would be full of this kind of complaints.

A good thing would be to look at your logcat for instance. Sometimes it gives valuable information on crashes...

/proc/last_kmsg could give you a hint as to why your phone crashed.

Regards,
[Galaxy S III Original Android Development] amirsardari:
Revolution HD has aroma installer and when I install it I didnt check force 2d rendering option . so its not activated . I dont Know why someones Trying to persist on this , that this is not kernel related !!! evrey roms and every kernels may have bugs and this kernel isnt made with GOD himeself so stop persisting on other subjects and help developer to solve this
[Galaxy S III Original Android Development] Anakha56:
Part of the trouble shooting process is to ask questions. So far there is not much to go on to find the problem hence the reason for trying to get the most information. So just chill & follow the process of elimination.
[Galaxy S III Original Android Development] mariosraptor:
I ain't persisting. It is you that have the problem. It is you that brought this up. If it is 2 people with the same rom and hundreds others have no problem then there is something wrong with your configuration.

Please state all info that could help. Uv. Oc any scripts. Super charger and other tweaks.
[Galaxy S III Original Android Development] amirsardari:
when i restored stock kernel that comes with rom the problem solved and lags are gone so its not misconfiguring its kernel related

i dont uv or oc and dont using any scripts just ordinary use with no other customizing
[Galaxy S III Original Android Development] EViollet:
Your conclusions are wrong. Just because it works with stock kernel doesn't mean the problem lies in this kernel. It just means that the problem APPEARS with this kernel. It could be hidden by the other kernel.

So, either you stick with stock kernel, or you accept that the people here ask you questions (which may appear stupid) about your setup in order to pin down the problem you're seeing.
[Galaxy S III Original Android Development] richyb86:
What else can he (and I) look for to help us out. I'm getting the same laggy home screen switching also. I'm on omega 27.2 running this kernel atm.

I switched back to stock DLIB kernel and that was smooth.
[Galaxy S III Original Android Development] amirsardari:
yes i agree u are right . so till now .

1- I have revolution hd .

2- 2d rendering is disabled

3- no uv or oc or script .

laggy with persus smooth with stock
[Galaxy S III Original Android Development] zykic:
I think "video.accelerate.hw=1" is just an boolean option to trigger hardcoded/framework.

So video.accelerate.hw will mean nothing if hardcoded/framework does not read the value and force them directly in to the codes itself.
[Galaxy S III Original Android Development] onurerler:
Now i full wiped and installed InsertCoin ROM(instead of ARHD 11) and installed perseus kernel than still laggy on scrolling. Than i installed siyah kernel with pegasusq governor and still laggy on scrolling. Than i changed governor from pegasusq to lulzactiveq than lag gone and everythings is smooth.

it seems to this problem not kernel or rom releated but governor tweak releated.
[Galaxy S III Original Android Development] zykic:
Well, you should do the opposite.

Flash stock ROM and then flash Perseus kernel. If the lag's still there, it's kernel's fault. If not it's the ROM's fault.

Since I and many other guys here are not using the ROM and do not face the issue. I guess it's the ROM's fault. Anyway I can be wrong.

Edit: Now I guess the same as onurerler. Since Perseus kernel's performance is directly related to pegasusq governer so if the ROM adjusts the governor value, which will work better than stock value for stock kernel, the result can end up badly on Perseus kernel.
[Galaxy S III Original Android Development] AbuYahya:
Deleted my mistake
[Galaxy S III Original Android Development] diego9016:
Then why don't you just use stock if it works better? :confused:
[Galaxy S III Original Android Development] onurerler:
Because there are freezing problems on stock and siyah kernels
[Galaxy S III Original Android Development] EViollet:
So if I understand correctly, you have lag, particularly with the launcher?

Have you tried another launcher?

Have you tried the latest Siyah kernels? Freezing issues seem to have been fixed on it.

I am, however, quite surprised that you have freezing issues on the stock kernel. This may be proof that something is wrong with your setup. You're the first person I read who has issues with the stock kernel...
[Galaxy S III Original Android Development] onurerler:
Now i am testing siyah kernel's last version for an hour. there is no freezing problem occured yet and with lulzactiveq governor scrolling is so smooth.
[Galaxy S III Original Android Development] hamma:
Maybe this (http://xdaforums.com/showthread.php?t=1369817) might help choosing the right governor.
[Galaxy S III Original Android Development] richyb86:
Audio benefits. Player pro sounds good with this rather than stock. Siyah was running hot a lot of the time and I don't adjust any voltages or need that level of customization.
[Galaxy S III Original Android Development] cink40:
I do not believe so:

I have exact same config (insertcoin+perseus default config, pegasusq governor) and i do not have any lag, I extensivelly tried everything (contacts (600+ contacts) scrolling, settings - second, third layer...) and i do not have any lag whatsoever...
[Galaxy S III Original Android Development] vBB:
Guys, is it normal that when I switch off my phone and then switch on (not reboot, manually off/on), my battery stats stayed as I wouldn't have rebooted phone?

Example

, when I'm entering battery stats (in settings menu) I have e.g. 5 hours 13 minutes 24 seconds on battery power, I exit from settings, and rebooting my phone (there is no difference between manually off/on or reboot), entering settings -> battery, and I can see e.g. 5 hours 13 minutes 48 seconds on battery power. Battery graph is the same, the same are all other statistics, just like I wouldn't have rebooted my phone. Is that normal situations with that kernel? Or maybe it depends on ROM itself, now I'm using ARHD 11.0, Or even it must be like this on our SGS3?
[Galaxy S III Original Android Development] onurerler:
Ok so plase compare scroling with lulzactive governor enabled siyah kernel. if it will be same smoothness i am going to sell my phone
[Galaxy S III Original Android Development] cink40:
Start selling...
[Galaxy S III Original Android Development] amirsardari:
im going to test it and will inform result

EDIT: I flashed Siyah-s3-v1.7b4 with luzactive . scrolling lag is gone now . BUT setting menus and sub menus intering and exiting animations isnt smooth yet . I think this is JB android Build Bug . actually android is a laggy operating system because its windowed base and its not built for touch devices at first like ios that is threat base . so i think we shoul wait for next build . honestly i didnt see very difrencess beetwen ics and JB and Project butter is sucks
[Galaxy S III Original Android Development] Flypwnz:
Oh god why? Damn it. Just tweak governor!

Like this:

echo "60" > /sys/devices/system/cpu/cpufreq/pegasusq/up_threshold

echo "20000" > /sys/devices/system/cpu/cpufreq/pegasusq/sampling_rate

echo "10000" > /sys/devices/system/cpu/cpufreq/pegasusq/sampling_rate_min

echo "2" > /sys/devices/system/cpu/cpufreq/pegasusq/sampling_down_factor

echo "30" > /sys/devices/system/cpu/cpufreq/pegasusq/down_differential
[Galaxy S III Original Android Development] AbuYahya:
I don't think the following entry will do anything as fixed

echo "10000" > /sys/devices/system/cpu/cpufreq/pegasusq/sampling_rate_min
[Galaxy S III Original Android Development] onurerler:
Thank you very much !!!!! that's it :)
[Galaxy S III Original Android Development] AndreiLux:
No offense, but let's try to keep such things out of the thread, no need to see what every single user's settings are; voltages are here with the whole ASV table for those who need it. People who don't know their stock voltages shouldn't be overclocking/undervolting in the first place. I set up the defaults within reason, so keep such things to your signatures or another thread.
[Galaxy S III Original Android Development] AndreiLux:
Yes. But more advanced things will be coming when I have my device.
[Galaxy S III Original Android Development] BoneMo:
so the important question is ... Have you ordered SGS III ? :D
[Galaxy S III Original Android Development] AndreiLux:
:rolleyes: :p Yes but I want a blue one and I hope they appear in Europe and here by the end of next week.
[Galaxy S III Original Android Development] BoneMo:
they will be available on monday 11th of June in Czech Republic...so maybe in your country too
[Galaxy S III Original Android Development] bala_gamer:
fine :) people should know the stock values before OC/UV like you said.

btw whats the threshold temperature limit where the cpu underclocks itself due to heat?
[Galaxy S III Original Android Development] galaxy_s:
Nice kernel man, love that I can now OC to 1704mhz and its smooth as. Haven't experienced any bugs!
[Galaxy S III Original Android Development] ttav:

how did you fix the wifi module in your kernel

could you share here?
[Galaxy S III Original Android Development] AndreiLux:
The modules are fine, you're just compiling it wrong, they need a second stage compilation.
[Galaxy S III Original Android Development] lukemo:
Yes this is what I meant...I'll try to lower voltage a little bit more.
[Galaxy S III Original Android Development] KennyLegend:
I'm well aware of this. That's why I asked here cause if I'm not mistaken it was AndreiLux & Entropy who initiated and analysed the different charging currents used on the S2.
[Galaxy S III Original Android Development] shahulvm:
Yep, they even went at length to explain various wakelocks...Good to see him here now..

@Andreilux - can you please make the kernel insecure and also add bash shell if possible, hope its not much of a trouble :)
[Galaxy S III Original Android Development] AndreiLux:
Done.
[Galaxy S III Original Android Development] bala_gamer:
ignore it
[Galaxy S III Original Android Development] shahulvm:
Can we make the kernel package as a cwm one pls..easier to install...though am using my own version on cwm :)
[Galaxy S III Original Android Development] stfudude:
Have you had a chance to try the real Project Butter in Galaxy Nexus? try that and tell us again how Project Butter sucks. Samsung hasn't fully optimize S3 with Project Butter yet, but we'll get the "real" PB soon enough. For now, Perseus is the closest thing to PB then any other JB kernel for our S3.
[Galaxy S III Original Android Development] AndreiLux:
With all due respect, you're talking out of your ass with that reply. Also if you have lags then it is caused by the configuration, you're free to tweak it as you want such as the following guy:

Those are VERY aggressive settings, way beyond what stock even offers. I don't recommend this out of battery waste reasons, but, you're free to use them as you want, but just don't come screaming about worse battery life. Lags also highly come from the hotplugging mechanisms, so if you have issues you can reduce the hotplug_rq_x_y settings in the governor. Again, this will come at a cost of worse battery life.

I also will not include any other governor (Beyond Peformance as a synthetic fail-save for tests) as with the current available settings in PegasusQ you can pretty much emulate any governor's behaviour, as pretty much every piece of logic is configurable.

[HELP] Touchscreen not responding after Perseus24.2

@ AndreiLux

Phone status : GT-I9300 Stock Rom I9300XXDLIB with Perseus23 lockscreen fishnoodle.koipond-1.apk (live wallpaperKoi Pond)

Yesterday I flashed Perseus24.2 through Mobile Odin. At restart the screen went "berzek" with white and blue stripes.

So I guessed the flash went wrong and I flashed back Perseus23 through Odin

The phone restarted fine but I got stuck at lockscreen because of touchscreen not responding.

I wiped cache and Dalvik cache to no avail

I reflashed stock XXDLIB no results

I wiped data. Phone restarted and got stuck at starting screen (language setting) because of touchscreen not responding

I flashed a 3 files stock firmware I9300XXALE8 MODEM_I9300XXLE8 CSC_OJV_I9300OJVALE7 Same problem : touchscreen not responding.

As I was stuck on lockscreen (swipe only) I supposed that maybe the live wp had interfered with the flash and I tried to unistall it through adb but unfortunately the phone wasn't in debug mode when all went wrong, so adb could not find the device (only in recovery).

I installed Aroma file manager 1.5 in recovery. I accessed data/app to try to delete the live wp apk (fishnoodle.koipond-1.apk) but found that it was no more in the app folder. There was now a fffff.....hh.bin file that I could not delete because as the touchscreen is not responding I could not select the file.

All I know about Android I learned it through reading XDA posts. So consider I am nothing more than an "educated noob" and I don't know if what I did was correct. But it seemed logical to me before coming on the thread to look for some help.

From your point of view, is there any software trick that could help me recover the phone,or should I consider that it is a hardware failure and I have to change the whole front panel (Amoled and digitizer).

Thank you for your help
[Galaxy S III Original Android Development] AndreiLux:
Did the touchscreen work in Aroma? Try a ROM with Aroma installer. If the touchscreen doesn't work there, then you can consider hardware failure. For my part I have nothing in the kernel that could cause this. Edit: Or a touch recovery.
[Galaxy S III Original Android Development] GrimPivo:
Can you recommend the Pegasusq settings for more-or-less balanced ui/battery functionality?

Or maybe - what's your choices? ;)
[Galaxy S III Original Android Development] :
Try Android Revolution ROM, with i/o / ext4 improvements. I feel it a lot better, reduced lags by 80%. Not placebo, I'm pretty sure.
[Galaxy S III Original Android Development] Lannyx1:
confirm!
[Galaxy S III Original Android Development] Flypwnz:
Only 5% higher worse battery life. With undervolting same as default governor settings.
[Galaxy S III Original Android Development] :
Lucky you.
[Galaxy S III Original Android Development] Bushido76:
I'm pretty sure that you will feel a smoother UI. The applied tweak changes the ext4-journaling mode to "journal_data_writeback" at sytem-, data- and cache-partition, which leads to faster write operations. But there is always a back side of the medal. In case of freezes and reboots there is a higher chance to corrupt the file system. So I wouldn't use it on my daily driver...
[Galaxy S III Original Android Development] nfsmw_gr:
Or you can simply go to android revolution rom and download the ext4 tweak zip and apply it to your rom! :)

I'm using it on Foxhound which is the best rom i've used...(i haven't seen difference though,this rom was great from the start.)

Have you ever done kernel for ICS? I have omega rom 13.1...
[Galaxy S III Original Android Development] crash_194:
Just thought I would add a bit of feedback!

Firstly thanks for sharing this stuff with us all, you must devote a lot of time and effort to developing this kernel.

I only bought my s3 last Saturday and rooted and flashed it Wednesday with your kernel and the android revolution Rom. The phone came with ICS and I haven't noticed any real performance differences since flashing the JB Rom and your kernel. The one thing I have noticed is the battery life is a lot better though.

I have noticed what I would describe as a micro stutter every now and then but it's just like what was present in gingerbread on my S2. I've always wondered if this could be a touchwiz related issue. Other than that performance is really good and I've had no force closing or issues with anything not working properly.
[Galaxy S III Original Android Development] schrickm5:
Thanks for the kernel Andrei.. At the moment it's working flawlessly... And I've tried them all. I am on stock JB (Poland).

No lags and quicker than than stock on my phone. :thumbup:
