All of those things can be done in other apps and aren't kernel specific. And although it's nice other kernels provide the CPU Idle interface, changing it without full understanding of what it does is meaningless, added to the fact that it does nothing for when the device is actually on screen-on.
[Galaxy S III Original Android Development] schrickm5:
The development as it is is really great on this kernel.... Keeping it simple but of the highest quality and with superb production values is why I love this work.
[Galaxy S III Original Android Development] AbuYahya:
Is step 5 of GPU freq implemented?

can we measure if it is or not?

The reason why ppl ask for a tweaking app is because their unaware of the others apps that fulfill that function or their weary of writing and deploying scripts.

Providing there is willingness to learn, they (and me) just need a bit of educating.
[Galaxy S III Original Android Development] nodstuff:
To see if your GPU script has had an effect just do this:

For overclocking:

Cat /sys/class/misc/gpu_clock_control/gpu_control

For undervolting:

Cat /sys/class/misc/gpu_voltage_control/gpu_control

And see if the values present in these files mirror the values you have in your script.

Setcpu can be used to overclock and undervolt the CPU and to change I/o scheduler and governor settings.
[Galaxy S III Original Android Development] AbuYahya:
Although it tells us the init.d script is working,

But does this show that their taking affect on the GPU?

or is this just the configuration input that your outputing?

edit

even in these files there appears (to me ) some inconsistency if (without any init.d)

voltage is from step 1 -5 but freq is step 0-4 ??mismatch.

so is voltage step 1 matched with freq step 0 or freq step1?

threshold is 1 to 4 all with up & down.

but the lowest step should only have an up and the highest step should only have a down.

this is why I'm wondering what is physically taking affect on the system

I hope Adreilux won't leave us (the S3), like Gokhan and codeworkx... :( otherwise I think I will sell my phone then!
[Galaxy S III Original Android Development] AbuYahya:
at the moment there's no other real contender unless your after a bigger screen.

S3 and note2 are similar in terms of CPU 100MHZ different if OC stable (1.7 vs 1.8) , GPU same, screen is larger if you like that (which I do) and battery is better (due to lower voltaging to CPU and better screen efficiency), and 2GB of RAM but my RAM has never been full even running Linux with might KDE GUI in chroot.

Xperia T - average hardware and 1 GB of RAM, unable to pull battery -risky if developing

Nexus 4- alleged to be similar to LG optimus G - IPS screen not seen myself but apparently less contrast/sharpness the Amoled screens, also Google dropping SD space to 8GB to force people to use their cloud storage.

HTC one X - bit old next model probably came out soon, then feel gutted.

(Edit. One XC is apparently 1.5 dualcore 1 gb RAM, 4.7" capacitive screen - again small upgrade)

Personally if I was to pick I would go for Note 2. but would I pay £200 on top of SGS3. not at this time come April there will be another flagship with more significant differences in hardware. or at the very least wait for N7105 model to be widespread

sorry for off topic

I hope he doesnt... and we shouldnt clog up his development thread like everyone did on gokhans which frustrated him and made us loose a wonderful dev.. i love this kernel and am having high hopes as this is the only one of the few actual developmental kernel for our s3.. glad we still have perseus and andrei with us..
[Galaxy S III Original Android Development] AndreiLux:
I don't plan on getting any new phone until next year at least, so no. I also talked with Gokhan if he does leave I'll port over all of the Siyah features over and at least maintain it if needed. Anyway people need to stop crying like babies who just lost their pacifiers, it's not helping either.

I also don't care what one posts in this thread as long as it's not blatantly stupid stuff, then I'll just call you a moron.
[Galaxy S III Original Android Development] wl3gan:
Perhaps facilitate this tool also can help us to understand more about the effect of the setting after doing some research on the meaning of the setting. I guess a lot people is also concern about the how the phone run and battery work after the screen off. It might possible allow more user to feedback the result for various setting combination to help you to further fine tune the kernel.
[Galaxy S III Original Android Development] AndreiLux:
It's not like the kernel does magic or some kind of voodoo behind the scenes, I know what it does and how the hardware functions, and what is best and effective. CPUIdle is just one of the things which should just be left as it is. The same logic goes to the CPUFreq governors, I won't implement anything else beyond pegasusq because it doesn't make sense to use anything else than pegasusq. If you want to tweak things, then learn the configurables there, as I already said once, you can emulate almost any other governor's scaling behaviour with just changing the settings. This is a case of "user doesn't know best", and I won't invite useless features or settings into the kernel.
[Galaxy S III Original Android Development] wl3gan:
Ok, thanks for your advise and information
[Galaxy S III Original Android Development] ring_GT:
Any updates?
[Galaxy S III Original Android Development] nfsmw_gr:
Any updates in general..?

Not that there's any bugs or that the kernel doesn't perform well enough...i'm just curious if there's future plans for next versions. :)
[Galaxy S III Original Android Development] AndreiLux:
- Harmonize the features between the S3 and Note2 versions of the kernel, should be easy.

- Get FM radio working on 9305.

- Rewrite GPU interfaces with completely different logic.

- Top secret feature that I've started working almost 6 weeks ago but didn't manage to get it working, so I abandoned it out of frustration, I want to restart and try again, if it works, it'll bring the single largest boost to battery life out there for this device.

- Some new controls for other voltages...

- Some other things (I'm really vague, aren't I? Just don't want to promise anything)

I think that's the long-term plan and the features I consider for the kernel to get out of alpha stage :p
[Galaxy S III Original Android Development] borjaag:
You're just a genius!

You are the man, this kernel is so stable at the moment and I appreciate your work alot. Soon donation.:good:
[Galaxy S III Original Android Development] SirCanealot:
Andrei has clearly mastered teleportation and when your battery hits 10% he will teleport to your location with a hand crank and top you up. This will also lead to him having the largest single bicep in the universe and will end in him winning all strong man contests in the future. He will then use the money from all the competitions he has won to create an army of monkeys with typewriters and a time machine which will be used to create a more efficient kernel which will double our battery life.

Am I close or am I drinking too much coffee today? Or not enough perhaps? :D
[Galaxy S III Original Android Development] eseregin:
Guys don't you think that "Gökhan Moral's port of Voodoo Sound" sounds worse than stock? To noise high freq, not so "air" in low freq...

I think... Better remove it... Understand that this is very individual - sound quality - but for me it is clear that this cheat with sound does not improve sound
[Galaxy S III Original Android Development] AndreiLux:
You're free to configure it or even disable it if you want. And its not a cheat.
[Galaxy S III Original Android Development] narcosis34:
Andrei is there a chance that we can see an app like extweaks? That would be great!

Mr. Andrei, I'm a noob with this kernel stuff... I would like to ask you... In a few words what exactly this kernel does? I didn't understand much the first page... Sorry for my noobness. :D
[Galaxy S III Original Android Development] AndreiLux:
Over stock, for noobs which don't configure anything at all, and don't do any undervolting :

- Better battery life

- Better screen sharpness and colours

- Smoother

- Better sound quality
[Galaxy S III Original Android Development] JohnCorleone:
AndreiLux, where can I find the ROM that was,mentioned that you use? I can't remember the name Fox Hound or something like that (maybe way off on the name) it was mentioned some 20 pages ago and I can't find it. Thx

Hi. Thanks for the response. Ive been trying mostly stock jb roms in the past weeks and battery life is so bad for me. Now back on ICS - awesome battery life. And judging by the changelogs and testing - your kernel is so smooth and battery friendly for ICS. Ive seen another user who reported this bug. Basically i hit the back button and it puts me in a state when i click on something it shows the right thing for a half second and goes back where i have been. Closing app and trying again fixes it. It happens most of the times. If Sammy is not going to fix battery life in JB i will have to stick with ICS for long time. Thats why i asked only if you have time to fix the little problem so your kernels will be best for S3 - JB and ICS. You already did great job and i respect you alot.

P.S. small apk like stweaks for your kernel will be great idea for the users. I will donate soon. Cheers buddy!

[Galaxy S III Original Android Development] :
Agree. But I feel UI response [like scrolling] lower over stock, but on the other hand, videos and tasks which needs more power are much better.

Not complaining, if I need to choose between UI and heavy operations I would choose heavy operations, so it's perfect for me.

Of course, there are more stock ROMs coming, and more improvements coming to your kernel, so, no rush and I'm not desperated.

Thanks for your kernel, simple and stable.

btw, what's actually the special screen sharpness when you are watching videos on stock video player, or viewing photos on gallery? I only know that you removed/disabled it.
[Galaxy S III Original Android Development] vegeta1:
Finally a kernel My S3 feels alot better with , Biggest Thankyou to Dev For His Efforts And Hard work ....

Thankyou so much mate for this kernel :)
[Galaxy S III Original Android Development] pride_kr:
Ok I see... youre right Im not good by doing undervolt things, kk

Iam having a great battery life with stock kernel. about 1d 12hs in light use, syncing e-mail, facebook, whatsapp and weather. HSDPA turned on the whole day, making some phone calls... thats all.

I really want to try your kernel, seems interesting, but Im affraid about battery life.

Ive tried Phenomenal and even in normal I had some random boots, and at least for me battery life was worse than stock.

I am looking for a good UI responsiveness and a great battery life.

Oh, and I installed that AC!D mod... will this interfere with the better quality sound that you mentioned?

Regards
[Galaxy S III Original Android Development] Kaboosey:
There's no need to undervolt by using this kernel, at least for me. Just flash it and enjoy. In my own usage, this kernel does not give me random reboots and stuffs. Battery life is better than stock for sure. UI responsiveness is excellent for me.

That's my opinion though on this kernel. No complaints at all for me. But remember, everyone's usage is different.

I suggest you to try it since it doesn't hurt to try. No money wasted and stuff. :)
[Galaxy S III Original Android Development] Falamo:
thanks for the hard work AndreiLux!

What about swap in the last released version?

And, it is possible to have the f_mtp_samsung working on OSX?

With these, the kernel would be perfect for me
[Galaxy S III Original Android Development] EViollet:
Hi.

Last time I tried, this kernel DOES support swap. Have you tried it?

Off topic question: why would you want swap? Last time I tried it was aweful: lagging all the time, Chrome eating up all the swap memory, etc. I tested for several days and reverted back to no swap. So, unless you have magical settings I don't, then I would hardly recommend swap.

Regards,
[Galaxy S III Original Android Development] Falamo:
just to test this: http://xdaforums.com/showthread.php?t=1888081

[Galaxy S III Original Android Development] invisiblebm:
Already tested. Perseus works much better without it. If it was something good Andrei would recommended it.
[Galaxy S III Original Android Development] AndreiLux:
As the others already said, Swap is already in and works. I tried that MultiTaskingFix for a few days but it gave me laggy UI because it started swapping too aggressively, so I just removed it. I find that I'm fine without it.

As for MTP, sorry, I forgot about that. I'll have it fixed in the next version.
[Galaxy S III Original Android Development] Falamo:
yes, the kernel works fine as it is, and if you have already tried I have confirmation that it is better without it.

AndreiLux not apologize to us, you are working very well and very hard, on this kernel!

So, thank you!
[Galaxy S III Original Android Development] zenosteam:
i have the same lag experience with MultiTaskingFix ,i prefer supercharger
[Galaxy S III Original Android Development] :
Don't talk about supercharger, otherwise AndreiLux will spend 1h of his life writing about how supercharger is "GREAT". ;)
[Galaxy S III Original Android Development] Jmldsilva:
Supercharger ? Can you explain how great is? What app you use to manage speeds...
[Galaxy S III Original Android Development] MuertoKo:
It was sarcasm :) Andrei explained some times in some posts how he feels about those tweaks like supercharger, just avoid chating about them here, or better, avoid using ;) It's always recommended to touch yourself the system if you know what you so, otherwise leave it as Rom/kernel :)

[Galaxy S III Original Android Development] trein91:
Hey, andreilux could you please implement higher charging rates? That would be great, especially for the usb charging rate which is too dam slow. (1200mah ac and 900mah usb like siyah would be great)
[Galaxy S III Original Android Development] robogo1982:
Maybe some of us do not want to fry our batteries with the higher charging rates?
[Galaxy S III Original Android Development] EViollet:
I'd actually be more concerned by frying my computer's USB port.

Quite frankly I don't see the point in raising the charging rate. The risks seem to outweigh the benefits to me, but if people want to do so, why not? The values are configurable using the system files, and the default values are completely harmless, so you shouldn't be worried.
[Galaxy S III Original Android Development] vivelafrance:
TL;DR: before flashing

What does TL and DR mean please? thnx
[Galaxy S III Original Android Development] robogo1982:

[Galaxy S III Original Android Development] trein91:
Maybe some of us dont care about the 5% decrease in battery life? (I have 2 spare batteries) It wont fry your charger, do some simple research first please. 900mah is perfectly safe for USB3 ports.

Can anyone confirm that Power Saving mode isn't working with Perseus Kernel ? This toggle among other things is supposed to limit cpu performance (which in my mind translates to underclocking or core limiting), in order to save battery. Although it works on stock kernel and on Sayah kernel as well, i can't notice any change in Perseus. Not in the CPU frequency or scaling and not in the synthetic benchmarks.

I'm on ARHD v12 with Perseus 24.2 Alpha installed.
[Galaxy S III Original Android Development] Falamo:
i can confirm, but i never use that so for me it is no important
[Galaxy S III Original Android Development] Cy4n1d3:
Dead Trigger is pretty much lagging while playing on power saving mode, so I guess something is working.
[Galaxy S III Original Android Development] vivelafrance:
Yeah I confirm too. In my opinion, Kernels like this one or Phenomenal are supposed to replace power saving mode anyway. They do what "power saving mode" does, but better.
[Galaxy S III Original Android Development] ArbiterGR:
Well i've even played The Dark Knight Rises in power saving mode and the game performed flawlessly and so did Dead Trigger, although i did notice performance degradation while using chrome (!), so something definitely isn't right. Unless AndreiLux has disabled support for this on purpose.

I have to agree with this. This kernel in particular has an amazing battery management, but in my case i need the power saving mode to limit the cpu and display's tone while for example use tunein radio streams (while at work) or using endomondo for hours while cycling. It was working wonders on stock kernel. Imagine my surprise after using endomondo for a 5 hour long workout, the battery would be still at 75%!
[Galaxy S III Original Android Development] andreasy:
May I ask if with the latest DLID official release, the kernel source was also released for developers so that we can expect a Perseus update with newer kernel?

On the other hand, I see that the kernel date for this ROM is Sept. 28 (Ver 3.0.31-256827) and I'm wondering, maybe it's the same with previous DLIB release? My thought was that if I install the kernel I will go back to older version but now I don't know how it goes.
[Galaxy S III Original Android Development] andip71:
Hi,

no, there are no new sources released so far. It is still Samsung update 5 which is around. However, kernel developers can baseline their kernel with the ramfs of DLIH kernel. But also not changes expected after first inspection.

Harunjo has done a quick comparison and found just the proprietory exfat modules have been changed. Not more.

So in a nutshell: This kernel uses still the latest possible code :)

[Galaxy S III Original Android Development] nfsmw_gr:
Andreilux do you think it's possible to upstream kernel version from linux main kernel tree?

I see nice changes like this :"Merged 3.0.45 and 3.0.46 - this last one contains a very specific noteworthy patch which fixes a serious bug that was triggered when the cores were onlined/offlined. Its been present in Linux kernels for quite a while but its now fixed thanks to the marvellous Linux kernel maintainers. It also makes the device wake up from sleep a little bit faster. I suggest you take a look on my github for more information about this patch" -franciscofranco
[Galaxy S III Original Android Development] AndreiLux:
Another fancy over-dramatic patch explanation by Franco, if he's talking about [CPU hotplug, cpusets, suspend: Don't modify cpusets during suspend/resume], as there's nothing else hotplug related in 3.0.46.

That patch does nothing at the moment for us because it fixes a problem related to CPU sets, something the kernel right now isn't even compiled with, and which makes no sense on a mobile device even if it were enabled. So no it won't make the device wake up any faster.
[Galaxy S III Original Android Development] nfsmw_gr:
