I think you should really head over to the thread where the configuration experts are:

http://xdaforums.com/galaxy-s3/general/unofficial-boeffla-kernel-app-profile-t2621308

Why not asking in the rom threads, as this is not a kernel problem? Maybe they know why...

Concerning the crashing camera you said that this issue is ROM related (cyanogen mod only?).

But could you have a look here:

http://xdaforums.com/showthread.php?p=57902992

And post #686

I am using this ROM at the moment and I am getting rid of this camera issue..

For me it seems like the Dev of the ROM says that this is a kernel problem.. I am confused..

I'm sorry but that's unlikely to be related. KSM takes about 18 minutes to set in. It scans /sys/kernel/mm/ksm/pages_to_scan pages every /sys/kernel/mm/ksm/sleep_millisecs milliseconds, in ArchiKernel it defaults to 100 pages per 500 ms, or 17 min + 45.135 s for 832 MiB.

I have some actual stats after having KSM + zram running for a few hours:

/sys/kernel/mm/ksm/full_scans:21
/sys/kernel/mm/ksm/pages_shared:1291
/sys/kernel/mm/ksm/pages_sharing:8083
/sys/kernel/mm/ksm/pages_unshared:54675
/sys/kernel/mm/ksm/pages_volatile:51935

KSM merged 8083 pages into 1291, saving ~28MB of RAM. 54675 pages = 224MB were found to be unique and 51935 = 213 MB to change between the last two scans.

This last stat led me to believe zram was skewing the results. So I disabled it, used the phone a bit (opened apps, etc.) and set pages_to_scan to 213027 to scan the memory faster. These are the results:

/sys/kernel/mm/ksm/full_scans:17
/sys/kernel/mm/ksm/pages_shared:4819
/sys/kernel/mm/ksm/pages_sharing:32277
/sys/kernel/mm/ksm/pages_unshared:94599
/sys/kernel/mm/ksm/pages_volatile:95366

Now KSM merged 32277 pages into 4819, saving a whopping 112 MB of RAM! pages_volatile however is even higher than before. This makes no sense to me.

I hope this helps!
[Galaxy S III Android Development] andip71:
Well, the dev said clearly: Only apply the patch on an unmodded kernel.

There are kernels around which include "camera fixes", but mine is clean. I always was reluctant to include these workarounds.

So, it is no contradicting statement at all.

We all know Camera is a big work area in CM11. It is open for more than a year and still not fixed to work fine for everyone. And saying that, I think it will never be fixed completely.

You can try this camera fix, it replaces some rom (not kernel btw.) libraries in order to try and improve things.

Andi
[Galaxy S III Android Development] andip71:
What scares and concerns me most after looking at this: It runs for 17 minutes. And this means - work for 17 minutes, and of course ongoing scans.

So it looks like this will need a lot of energy. Any clue on battery consumption of this?

To me, it would not look appealing when I sacrifice battery life for some extra MB of ram...

[MENTION=1045701]lordbo[/MENTION]effla sorry for bothering which kernel of yours will work on cm based Miui 4.4.4?????????????

Sent from my XT1022
[Galaxy S III Android Development] andip71:
No clue. Probably none of my kernels.

MIUI always requires some extras in the kernel. I asked them months ago what to do to make it compatible with their rom, but I never got any response.

Seems they are not interested in allowing custom kernels to be used. And hence, I was also not interested to dig anymore.

You can try latest Omnirom stable 2.4 version. But I am quite certain it will fail.

[Galaxy S III Android Development] Egli.Kasa:
Can anyone one tell me the best config,lmk for cm12 latest beta 4 ?
[Galaxy S III Android Development] agusdallalba:
It turns out I made a mistake before my previous 6-hour test: I had been playing with the KSM parameters and I set sleep_millisecs to 500 by accident. The actual default in ArchiKernel is 20.

The pages_to_scan and sleep_millisecs parameters are just that; CPU throttles. When I put sleep_millisecs = 0 the 'ksmd' kernel thread does keep the CPU at 1.4GHz and it seems to sweep through the whole RAM consistently in 13.3s according to the full_scans file. So I guess that, if 213027 pages per 13.3s is 100% CPU time, then 100 pages per 0.02s (the default in ArchiKernel) is 31% of CPU time. 31% of 1400MHz is 437MHz and as expected my phone idles at 400-500MHz with KSM on. I agree that this is unacceptable.

However I had good results from KSM with sleep_millisecs set to 500 too. In that case ksmd should use ~1% CPU and in practice on my phone it's not enough to make the governor step above 200MHz. So all in all this gave me 28MB of extra ram for 'free' :good:. More testing should be done to find a good balance between power consumption and memory savings. For now I'll let it on overnight with zram disabled to see how it really perfoms with sleep_millisecs = 500.

When I used the cm based MIUI 4.4, I flashed the latest cm 11 boeffla kernel that was available then and it worked. The only thing i noticed was that it broke the inbuilt virus scanner that comes with MIUI but that wasn't an issue for me. If you're on slim based MIUI, the omni kernel works.

Cheers.
[Galaxy S III Android Development] j1gga84:
Thanks for your time,

So you mean it is a general problem of CM11 of all devices or only i9300? Because if I remember it right i9100 was fine!?

So I will try this fix and report back, before that I will flash NG kernel if this one is also unmodified!?

If it will not work I have to switch to AOSP I guess because I have to give that device back when my i9300 is repaired and then camera should work ;)

Andi at this moment I'm using AD 3.0 (CM 11) with frandom enabled and it seems all is working fine, it's better to disable or I can leave as it is ?

Except for a few "can't connect to camera" with stock CM 11 camera (that broke something that needed a reboot), I never had any problem and never needed a patch for the camera. I use FV-5 and Zoom FX pro (and eventually Snap HDR free) and always they works fine. Maybe I had a lucky hardware combination on my S3...

On CM11, Omnirom and all Samsung roms, you can gladly use frandom.

There was a reason for it. It is so long ago, I cannot remember anymore.

Had something to do with available freq multiplicators etc. But not sure anymore.

I Just remember, I tried 1700 for quite a while and it was not stable.

No, I am sorry. Then you need to upgrade finally your rom. I cannot provide another kernel variant, this does not make sense as all roms I know upgraded in the meantime.

You are not serious, or?

Sorry, could not resist to say that. Have you EVER read the OP of this thread?

I give you a small hint... the line starts with

"To tweak and configure the kernel, manually load and install the app "Boeffla-Config V2" from here"...

Well I use these LMK values and they are really stable and keep things in RAM

only thing extra I do was to push ViPER4Android to /system/app

zRAM is 400 MB on 2 devices

Here you are

48/60/72/95/110/153

And they are great for such damn multitaskers like me :D

Please try them

As for the previous LMK they are a bit aggressive, don't you agree ?

Thanks for support

---------- Post added at 07:55 PM ---------- Previous post was at 07:53 PM ----------

And I think it is the same that devil kernel has the 1920 MHz instead if 1900 MHz right ?
[Galaxy S III Android Development] myshakugan:
I tried the 10,20,30,130,140,150 lmk values but multitasking is nearly impossible with those. So I reversed them and using 130,140,150,10,20,30 right now and multitasking is smooth again. :P will test these values more and see how I can get better results.
[Galaxy S III Android Development] agusdallalba:
Followup on:

So I woke up, checked the weather, sent a few messages and browsed a bit in Chrome to have an idea of how well KSM works in a normal, light use enviroment with zram disabled and sleep_millisecs = 500. These are the results:

/sys/kernel/mm/ksm/full_scans:55
/sys/kernel/mm/ksm/pages_shared:2848
/sys/kernel/mm/ksm/pages_sharing:21077
/sys/kernel/mm/ksm/pages_unshared:45080
/sys/kernel/mm/ksm/pages_volatile:107129

So here KSM saved me 75 MB of RAM. ksmd's CPU usage on top is only ~7% at 200MHz and ~1% at 1400MHz. What I'm not sure of is how well the CPU can sleep when it has something running every 500 ms. My guess is that this isn't an issue, given that the timer interrupt runs every 1 ms. So this is very cheap, CPU-wise, and offers enough extra memory to cache 1 or 2 apps, and that's great.

Does KSM prevent deep sleep? Check your time_in_state or use CPU Spy to see if your phone can still enter deep sleep. My guess is it does not prevent deep sleep, so the impact on battery life should be minimal. If it does prevent deep sleep than there is little reason to keep this discussion going in my opinion. The reason I'm asking is because you mentioned leaving it on overnight and in that case the phone should be in deep sleep >95% of the time, not spending the whole night merging pages.
[Galaxy S III Android Development] agusdallalba:
My phone enters deep sleep with KSM on, I checked with BetterBatteryStats. I left it connected to the charger last night, that's why full_scans was so high.
[Galaxy S III Android Development] Mostafa Wael:
well i guess KSM will not be needed that aggressive, as there is a patch from CM that solves the memory leak!!
[Galaxy S III Android Development] viktor92:
Oh my, LMK values are black magic... :rolleyes:
[Galaxy S III Android Development] myshakugan:

I didn't keep those values for long, just wanted to see what happens when you set abrupt values.

But with the initial values, I couldn't get multitasking done, so I changed my lmks and trying to see which suit my needs.

I don't know what to do and what settings are recommended for a good battery life, especially when phone is in use.

At the moment battery goes down quite fast when screen is on compared to my S2, DS is okay but could also be better..

Compared to S2 kernels there is not much that can be tuned for battery lifetime I think.. Or can you recommend some good settings?

Something I miss is the "minimum LCD brightness" for example, to make screen darker in lowest levels or gamma settings.

[Galaxy S III Android Development] Doppiadi:
I'm no Lord but I can tell you, you can use both. NG version performs better (Samsung stuff inside), non NG is Cyanogen code, less optimized for the device.

Difference NG kernels to normal kernels:

NG = next generation, it does use pure Samsung source codes only, not the smdk4412 kernel sources of the CM or Omnirom team anymore.

Feel free to do so, but I can tell you already now: It will not change anything.

The config app does not run itself, nor in the background, so it does not change any settings.

If you still have doubts, look into all your bc.log files in /boeffla-kernel-data and check if it ever writes to the readahead buffers without being told. It does not.

However, you - of course - need to change the settings back to want you want in the app first.

playing over a belkin car handsfree equipment ;) just try it and increment it by 100mhz steps if u run into troubles. 800mhz should be save as users have reported.
