[Galaxy S III Android Development] rowlers:
yes it is odd, exactly the same freeze with all other kernels and Zram, so it is NOT specifically a boeffla issue.

Could it have anything to do with modified LMK values? I don't know if my ROM has such this, but will confirm....
[Galaxy S III Android Development] andip71:
rowlers, good point!!!

In Boeffla with zRam, the LMK settings are slightly changed.

So if you use a rom that modifies these settings in a script, you should remove it.

This is what Boeffla sets:

echo "12032,14080,16128,18176,20224,22272" > /sys/module/lowmemorykiller/parameters/minfree

I'm totally fine with zRam, and since I do a lot of multitasking, it's a great addition to this kernel. Loving it so far.

[Galaxy S III Android Development] rulala:
hi , AndiP

I already long time use a script to make memory management like this.

echo "0,1,2,4,7,15" > /sys/module/lowmemorykiller/parameters/adj

echo "2048,4096,6144,8192,12288,16384" > /sys/module/lowmemorykiller/parameters/minfree

So, If I use boeffla (zRAM) , I must delete my script?

in other words, If I don't use zRAM , I don't need to delete it . Right?

Whether I use zRAM or not , I had better don't use that script?

thanks a lot. :p

Hey guys I use(d) an app called Android Tuner but with Boeffla it gives me issues... hmmm... how can I explain... it doesn't necessarily "uninstall" it but kinda blocks it from running... never seen anything like it... if I reflash Siyah all is well and if I flash Boeffla 2.11 then it also works fine... problems arise with 2.12 betas... all of them... what do you need to diagnose the problem?
[Galaxy S III Android Development] whiskerp:
I've installed 2.11b4 today in place of XXEMD3 stock and am very pleased. It's on the battery friendly setting and is noticeably better than stock for both responsiveness and battery usage.

Thank you Andi.

After many attempts at trying to make the mic work after installing 2.12 beta2a version, and no headway I think I'd just accept my faith and hope it gets restored some day since this is the first time in days av not had a single reboot and the battery life is phenomenon. Not a deal breaker though but would sacrifice google voice shazam and soundhound to have a perfect working phone.

By far the best battery friendly kernel I have used on my s3 so far. I couldn't believe my eyes, and I'm only using zzmove. I have been reading that there are other governors that can save more battery as well.. Will give it a try but until then keep up the great work on this kernel. Congrats on the job well done to the op!!

Quick update on 2.12b4, not a single problem, very fast and smooth. Not using zram as I don't need to do a lot of multi tasking but I tried it and it was fine. Best kernel yet!

[Galaxy S III Android Development] Yank555:
You just can't put it that simply ;)

Your PC worked fine with 512Mb RAM a few years ago as well, try Window 8 on 512Mb ;)

1Gb with current ROMs and current apps is way too little for proper multitaksing. As such zRam is a very usefull addition.

Samsung using 200Mb zRam in their 4.2.1 leak (didn't check the latest 4.2.2) proves they seem to have understood that 1Gb was too little for the i9300...

[Galaxy S III Android Development] maatsby:
Fair enough, I don't know that much about it, I just thought I would get the conversation started
[Galaxy S III Android Development] GzC:
But zram does give impact to battery life right? I like zram a lot, it gave me more multitasking and better performance in gaming, but I have to sacrifice my battery life for that. It's a hard choice. :banghead:

---------- Post added at 10:40 PM ---------- Previous post was at 10:33 PM ----------

Nice point, even the latest Galaxy S4 with 2gb of ram wasn't enough for such heavy multitasking. It took more than half of it's ram without any apps installed, just those Samsung's bloatware running. And yeah was quite shocked with it's storage too, 8gb used out of 16gb. :eek: Hope the 4.2.2 update for our S3 doesn't do the same thing like S4 does.

2.12-beta5

Hi all,

before I will disappar tomorrow morning for the next 6 days, here a minor maintenance release as a new beta:

2.12-beta5

Change Log (vs last stable 2.11)

* All functionalities of last stable kernel 2.11

* zRam support (configurable e.g. in Boeffla-Tweaks app, do not forget to restart after configuring)

* Linux kernel "upstreamed" from Samsung original version 3.0.31 to latest release 3.0.80 from 25.05.2013 (www.kernel.org)

* Additional charging rates for USB and AC charger

* Danymic fsync updated to version 1.2

* Debug info log in Boeffla-Tweaks app extended to include more zRam specific debug info

As always - download from homepage or via Load&Flash.

I hope this version runs stable and smooth now. I will be on a holiday trip to Vienna from Saturday to Thursday.

So, if you encounter any issues during that time, I can only recommend to report and flash back to beta4 or beta3 in worst case. But I am confident this is not required.

Cheers

Andi

Don't worry, battery life is not impacted by zRam at all.

JP.
[Galaxy S III Android Development] GzC:
One more question please, the zram implemented in the kernel was using LZO compression or Snappy compression?
[Galaxy S III Android Development] andip71:
Snappy Compression, GzC.

Andi
[Galaxy S III Android Development] gsw5700:
Is that right? I thought that by using zram you are effectively trading extra memory for CPU cycles (as you need CPU cycles to compress/decompress memory pages) Won't the additional CPU cycles take additional power, or, is the overhead minimal?

Sent via TCP/IP
[Galaxy S III Android Development] Yank555:
Firstly, it's so little you can ignore it, secondly, full apps being killed by LMK and reloaded by user (as opposed to 4Kb memory pages being swapped in and out) will use more juice than the compression.

But we're really talking way less than 1% of a full battery cycle in either direction, so nothing worth mentioning.

Even hardswap has no impact on battery, and I've been using either of both (hardswap on ext SD / zRam) for about 2 years on several devices and loads of different ROMs.

JP.
[Galaxy S III Android Development] MIKEMON:
Yes very true, it has no effect on the battery only for multitasking, but not necessary

AndIP thanks for the update, but beta4 so wonderfully stable, that I hope beta5 only

improve everything, but no longer needed
[Galaxy S III Android Development] andip71:
Thank you. Getting these words by you is really compliment :)

Sure, current sound implementation is "just" version 1.2, I am happy to add other functionalities when needed. And bug fix, as I think there are still some bugs in maybe.

By the way... speaker tuning and oversampling is both already in :) Unless you mean something else.

Andi
[Galaxy S III Android Development] gokhanmoral:
I think differently...

I would expect to see at least some references to voodoo and credits to Supercurio.

It's not I like him a lot but I respect him.

and even it is a very well refactored implementation, it is basically same as voodoo sound and since I worked on it a lot I can clearly see the resemblance.

I was trying to stay close to the original implementation, but even if I did not I would not remove "voodoo" references from the source.

you have even copied the custom modifications that I have made including the alsa functions and headphone/fm detections and so... it is perfectly normal and I can say that you are very good at cleaning/reordering code but having no credits in the code is just not acceptable.

I request no credits for myself but I request you to give proper credits to Supercurio.

I do not think anybody would mess with those registers if it was not his work at the beginning. and it doesn't matter how much time you spend making it look better, it is his original idea and implementation...
[Galaxy S III Android Development] andip71:
EDIT: Done in source and postings, topic closed.

Yes, I concur and follow your argumentation.

Will put some credits in the sources of course with next version, and will add credits on OP and homepage.

Got just forgotten, thats all.

Thanks for informing me.

Andi
[Galaxy S III Android Development] gokhanmoral:
you say it is forgotten, but I think it is intentional.

anyway, it doesn't matter.

you are warned and I hope you will be more careful in such matters.

it is written "(c) andip71" in the file ( https://github.com/andip71/boeffla-kernel-jb-u6-s3/commit/b74ac2441805946e9a258438d43af2c3893c047f ).

and I repeat: there is nothing original in that file and it is an exact replica of voodoo sound.

you can name it anything you want, and even Supercurio asked people not to use voodoo name anyway. but it doesn't give us the right to rename and copyright his work.

You need to realize that your work will still be appreciated after giving credits.

This domain (open-source) has the principles of contribution and every contribution is priceless, as long as you do not cross the names of the previous contributors.

I have no idea what you meant by saying "DONE!" but I think the credits should be in the source code.

of course there is no obligation on that, but considering you have put a copyright on that file you should at least fix that huge problem.
[Galaxy S III Android Development] andip71:
Credits are in the source code:

https://github.com/andip71/boeffla-kernel-jb-u6-s3/commit/09ce1c88cc76a501416bc972ef63378bb5d7dd47

And if you think it is intentional, then this is your opinion I cannot change and do not want to change.

For me the topic is closed now, and if you want to continue discuss this, please PM me.

Enabling zram (say, 400), will it consume more battery than zram disabled?

[Galaxy S III Android Development] nelsonw:
So, zRam can short the SD card's life, right? It's possible to make zRam on the external SD card? Bc I can use a fast class10 card and make swap faster. Just wondering. Sorry if it's crazy.
[Galaxy S III Android Development] axetilen:
zram is swapping in ram. swapping on sdcard is hardswap and swapping in the internal memory is softswap

we can easily see that zram > softswap > hardswap due to the reading/writting speed

zram doesnt damage ur sdcard and its totally safe. softswap does shorten ur flash memory llifespan and hardswap is the one which will shorten ur sdcard lifespan

class 10 sdcard is still much slower to softswap and zram

1 disdvantage of hardswap is u cant unplug ur sdcard while using hardswap and if u do it, ur phone is gonna freeze for sure. actually u can but it takes time
[Galaxy S III Android Development] nelsonw:
Thanks for your excellent explain. I wrote bc Andi says zRam is dangerous for the sdcard. Thanks again.
[Galaxy S III Android Development] axetilen:
I think u misunderstood him. someone asked him about "swap" in multitasking fix. it is a mod which creates 600mb of softswap, not zram => so softswap will damage the internal memory as I said ;)

Im using that multitasking fix too but I removed softswap scripts in that mod and just use zram
[Galaxy S III Android Development] nelsonw:
Yes, that's right. Sorry about that. Thanks!

Or after playing game n exit from game. When the screen hang can see the cpu stat on the notification bar show all cores at max.

Turn off the zram everything just fine n great battery life. Sometimes I do not believe that my battery still has so much left after a day use.

I am pretty sure zram related problems are when custom roms play with lmk settings.
