Hi everyone,
What about adding swap support to custom kernels to overcome SGW ram shortage? Couldn't post to dev forum so posted here. Please someone reply.
I have my SGW now for about one month and its my first android device.
I havevsome years ofvexperience with Linux and while i was playing around with my phone i have experienced som lag while switching homescreens on Go Launcher.
I have quite some stuff on screens and ex taskmanager widget shows me
that my mem is easily filled when doing some more stuff.
My phone got root and terminal also set up so thought
i go make a swap file on internal sd to give phone possibility
to swap mempages out of ram when needing mor mem.
Been there done that, saw that even if swap helper progs (i.e. mkswap,swapon,
swapoff) exist gives error that kernel lacks swap support.
Dont know why swap not implemented in stock rom, went ask internet for
custom kernel for SGW. Reading Kezras custom rom thread and beeing unable to post
questions to him on his thread , got me here.
I ve also read on internet that there are custom kernel for other devices with
swap activated. Though our fon has quite good processor it lacks ram,
so i wonder if custom kernels here have swap activated and perhaps start discussion here about pros and cons.
Thanx for any replies.
Hi its me again,
searched and found this thread for Htc that points out it could make sense to add swap to phons with little ram but strong cpu .
Check it out here.

But, is our Wonder short of RAM, or short enough to require swap partition on slooooow SD, or comcache using precious processing cycles to compress/decompress ??
Would using memory management, such as zeppelinrox V6 TurboCharger, not be more appropriate?
V6 Main thread
Latest Beta's
Without having to further reduce RAM for comcache!!
or swap partition on SD which is much slower than RAM?
But, I agree, it would be interesting and useful to have Custom ROM, which supported swap or comcache, even for the ability to compare and contrast.
But, there will always be a trade-off when using either comcache or swap....it's just a question of whether the individual user finds it acceptable.
Hi there irishpancake! Just testing the V6 supercharger myself seems pretty ruthless...keeping my used RAM at 230MB almost permanently and lag free! Doesn't quite have the same effect with a custom launcher but TW is flying. I think ur right about our device needing memory management more than anything.

@irishpancake
I ve tried the script you suggested,
and it 'feels' very promising.
I appreciate also your speakout for activating swap support in custom kernels/roms so anyone could choose freely what way to go.
Still virtual ram don't interferes with good memory managment and
with swapspace you have a little extra even if you dont use it and the
slow access is relativated through paging. Wonder if one can set page granularity in kernelconfig ?
By the way if anyone could point a
Rom/kernel developer at this thread as i cant. I would like to hear their opinion on all that.
Thanx for replies so far ....

Hi 2g11 man.....
sorry, I just saw your PM, about V6, and just to say, I find it definitely snappier, and as you have noted, very good on the memory management.
I do not have enuff knowledge to actually give figures or stats, but it just feels much faster, and responsive, lag-free.
I am still using the Update 9 RC4, so I will try out the latest version Update 9 RC6 ASAP....
I use Launcher Pro, just coz I hate TW, and it is remarkably good with the V6 tweaks........and I am still Stock ROM 2.3.6 [KJ6].

changing pagesize is no valid option to influence swapping behaviour.We have to stick to
"swappiness" kernel parameter which can be changed 'online' though.

@irishpancake I guess I didn't properly set the ADW Pro I was testing as the 'default' launcher as described by THE-E in another thread. Will try out the new script as well. Just wondering, do you use options 7,13 and 20 as described in Rio's Black Keys thread? Maybe some other options you've tried?

Works with any ROM
So, if you have Faux 11 kernel + this mod.

In technical terms, we are disabling CPU Rendering from the system so it force GPU to work on all Graphics.
So why not?
Would it hurt no?

you do not need this mod. just go to system/lib/egl and delete the first line android 0 0. this does the same thing as this mod. I did it on my phone and it works fine. No graphics problems . All hi tech games like asphalt,spiderman, avatar. cs portable, gta3 all play great. Videos do too. You can also add debug.composition.type=gpu to build prop and delete any other composition type that's in build prop to force gpu rendering for graphics

Thank you. Every one thinks it will break things. It is like saying I have a Land Rover with 4v4. Now, you're going up a hill and to run it up, you buy newer and better wheels. It still gets up, but slower. It would be a lot smarter to enable 4v4 so it can climb faster and more efficient. So GPU is supposed to run the Graphics Interface. Not the Processing Unit. Does it make sense? Of course not. Using GPU for its dedicated reason it is a way more reasonable thought. So why would you want it disabled?

Well it hasn't broken any apps for me.

I'm not sure why everyone is jumping on the OP so hard.. he stated clearly in the second or third post that it Works without breaking anything .. I flashed it on my AOKP JB build with no problems and it didn't break anything like the option in development settings does... for example .. xda app loads pictures perfectly.
Maybe test it next time before flaming give it a test...

RushAOZ said:
Because you're probably not using any old apps that haven't been updated for ICS. Not jumping on the OP I'm simply stating this mod isn't needed because the GPU is already rendering everything. CPU will only render old apps so if you don't have any old apps then this mod is essentially useless. You're not forcing the GPU to do something it isn't already doing.

OK.. then riddle me this.. Using the option in development settings breaks my XDA and my FRF app, meaning they wont load pictures in the app.. However this mod has not caused this side effect..
RushAOZ said:
This mod isn't needed. The whole reason GPU rendering exists in ICS/JB is for apps that were written on GB. GB written apps didn't support GPU acceleration by default. With ICS and JB apps are written with GPU rendering on by default.
Basically these settings ONLY effect old apps that haven't been updated to ICS/GB. This is why disabling CPU rendering will break some apps as experienced by some of you above. GPU rendering is supposed.to force the GPU to render old apps and while it works most of the time there are apps that you can't force and you get errors and artifacts. So many misconceptions with this setting lol. Just leave it on. Problem solved.

According to pocket now force gpu rendering is basically used to off load the graphical tasks given to the CPU in apps that aren't optimized for ICS. ICS has this option enabled by default when writing apps for it but with apps written on GB down to cupcake 1.6, gpu rendering when writing apps is off by default.
Basically, leave it on as its probably helping your CPU run older unoptimized apps more efficiently since it doesn't have to process the graphical UI for that app too.

Its also pretty hilarious that you say this and are bending it to make your self correct..
YES newer applications that are based on the newer SDK have the ability to do this Nativity regardless of what you have checked or unchecked..
BUT it is not ONLY going to be beneficial for apps that are not.. it will force ALL rendering through your GPU and leaving the computation to the CPU giving your system an edge.. while be it a small one, but never the less an edge as far as CPU processing times and Graphics quality output ..

kernel, or only with Faux, what Rom is compatible with....and so on.

Note2Core Kernel for Galaxy Note II N7100 / N7105 (LTE)
I am posting this here because it works on our LTE notes, since they all use a Qualcomm modem. I am running I on my AT&T note with no issues. All credit goes to g.lewarne - I am just posting here to so he doesn't have to maintain 2 threads. See his original post here
For the moment, exFAT formatted SD cards are NOT supported.
About this kernel
This kernel is built from pure Samsung GT-N7100 source, with modifications and tweaks to provide the best user experience in reliability, performance and stability. Built upon my experience firstly with NoteCore and then HydraCore for the original Note, as many of you know, I strive for the best
There are 4 versions of each kernel, for the International LTE model GT-N7105.
This kernel has all debuging removed - logcat, android log, kernel log, schedular log, etc etc all disabled. This is for performance reasons, so if you are a developer this kernel is probably not for you
Kernel Versions
There are three variants of the kernel for each device
STANDARD (STD) - 1.6ghz FSync() enabled
OVERCLOCK (OC) - 1.8ghz FSync() enabled
EXTREME (EX) - 1.8ghz FSync() disabled
ASYLUM (AS) - 1.920ghz FSync() disabled
The standard version, has no modifications to the processor clocks or voltages and can be considered a direct replacement for the stock kernel, and with FSync() enabled is completely stable
The OC kernel automatically scales up to 1.8ghz, with the proven voltages and stability from the perseus kernel (the same frequency table is used), and with FSync() enabled is completely stable
The EX kernel also scales to 1.8ghz, and has FSync() disabled. It offers by far the best possible performance. In rare circumstances you must be aware that this can lead to data corruption and the need to wipe / reflash a rom back to the phone. 99% of people will have no issues with this, as it has been extensively tested and proven on my previous kernel, but the risk is there. Dont go moaning to me if you lose your data and haven't got a nandroid backup!
The AS kernel is meant for the crazy ones. People who come from an asylum, those from the Note 1 know I am crazy, so this was meant for them. If there is a demand for the 7100 I will build that as well. I am not responsible if you are able to cook bacon on your device after running. It features up to a 1.920ghz over clock, and 640ghz on the GPU, it will go up, however for the moment we will run with 640. The phantom bug is that voltages cannot be set with SetCPU. Neither myself nor gavin know why. The code is spot on. So we don't get it. Lol. The source code is on github.com/glewarne
Kernel Features
- Built from official GT-N7100 sources
- 1.6 / 1.8ghz auto scaling
- Optimised VM memory settings, and global readahead
- Auto-rooting of any rom when flashed, even stock
- init.d script support
- CPU Voltage support through 3rd party apps
- Modified GPU DVFS utilisation steps for maximum GPU performance, far better than stock (this is NOT overclocking!)
- No logging / debugging of any kind for higher performance
- Decreased CPU frequency transition latency
- CRC32 slicing-by-8 algorithm
- SLUB allocator
- PEGASUSQ governor (default, others available)
- NOOP schedular, (default, others available)
- +50mb more free ram compared to all other kernels
- lots of other minor tweaks and changes
- ODIN TAR and CWM ZIPS available for all versions
- TouchWiz roms only

Yes, exFAT is not supported, we just found out. A fix is coming soon. Also videos in games such as zombie wood don't play. Fixes coming soon.
Nice to see another kernel here.
Can you please update the OP with a link to the original n7100/n7105 kernel thread? (It might make it easier for users to pop over there and see current discussion, etc.)
Also, I'm kind of curious what kind of difference people have noticed by blocking the majority of kernel logging. In theory, it shouldn't make make a significant difference, but I never got around to testing it, so I'm not sure how well the theory applies. (kernel logs aren't backed by persistent storage, so there's no real I/O overhead to it.)
Take care

Lowest ram I had was 51MB, and I use Sense 4.1. I would say using task killers help if your one of them people who want to see your ram high. If your device feels sluggish after use, use a task killer, or reboot.
I'm sure CM has that low mem problem though ither way. I saw someone posting bugs about it.

i said it numerous times... android is NOT windows. your free ram in linux => your system fails to work. your free ram in windows => you can open up more programs until the ram is full.
in linux it is better to have the whole ram full, not free. if you want more infos, you can search on the net.
When an Android app is no longer in use, the system will automatically suspend it in memory - while the app is still technically "open," suspended apps consume no resources (e.g. battery power or processing power) and sit idly in the background until needed again. This has the dual benefit of increasing the general responsiveness of Android devices, since apps don't need to be closed and reopened from scratch each time, but also ensuring background apps don't waste power needlessly

Android manages the apps stored in memory automatically: when memory is low, the system will begin killing apps and processes that have been inactive for a while, in reverse order since they were last used (i.e. oldest first). This process is designed to be invisible to the user, such that users do not need to manage memory or the killing of apps themselves.[65] However, confusion over Android memory management has resulted in third-party task killers becoming popular on the Google Play store; these third-party task killers are generally regarded as doing more harm than good.

wrong. they remain in memory but they will not consume anything. that's what cache memory means.

Let me introduce myself first. I have been developing software for Windows for almost 20 years. I love to tweak and tinker. That is what drew me to the Android platform. With that said, here are my findings:
I own a T989. I love the phone. I have tried numerous tweaks and scripts etc out there. In the end I found some very minor tweaks that I have done manually that make a noticeable difference in performance and a battery life.
The biggest increase in performance and battery life that I had noticed was going from a stock rom to CM 10. I am currently on CM 10.2 (and eagerly awaiting a stable version of CM 11).
With that said I noticed that if I changed just a few minor things CM 10.2 runs considerably faster.
Here is what I have done:
1. Disabled ZRAM completely. I have noticed that my phone boots faster with it disabled. I noticed that multitasking was not as good with it disabled but the phone seemed much snappier.
2. Changed Min Free values. I used the Performance Control app for this. My settings are currently as follows:
Foreground Applications: 16 mb
Visible Applications 18 mb
Secondary Server: 23 mb
Hidden Applications 42 mb
Content Providers 49 mb
Empty Applications 56 mb
This seemed to help a lot with multitasking and now it multitasks fast and the phone is much snappier and less laggy. So far my phone is very stable and fast.
3. Set SD Card Read Ahead to 2048.
4. I also left KSM disabled and left Allow purging of assets disabled.
That's it. My phone is rock solid stable and fast with these settings. I also noticed that my battery lasts about 15% longer. Even better than just switching to CyanogenMod 10.2 alone.
Let me know if it works for you.
I would absolutely love to try this, but I don't understand majority of what you wrote. I'm familiar with cyan though..

How do you disable zram entirely is what I'm wondering ?
*MEGA 4.4.2*GS2 4.4.2*2SHAYNEZ*
Disabling ZRAM is CM is easy. Under the performance menu just go to Memory Management > ZRAM. Select Disable. Reboot.
Oh I'm running slimkat on my i9205 mega and downloaded the performance apk. And I'm running beanstalk on my t989
*MEGA 4.4.2*GS2 4.4.2*2SHAYNEZ*
I updated the OP with new Min Free settings. I noticed that it wasn't as stable as I thought. After using it heavily all day I updated some apps in the Play Store and the launcher hung and everything was slow until I rebooted.
I then changed it to the new values above and used it very heavily. I made sure at least 18 apps were open then reinstalled those same apps from the Play Store (I uninstalled them first). So far no problems.
Moderator: Please delete this post. I accidentally double posted.
Is there a way to disable ZRAM on a rooted stock T989 running 4.1.2?
Thanks in advance,
rabilancia
As far as I know the stock ROM doesn't have ZRAM.

Running JMT8 right now, and this has been one of the best posts I've seen on this forum. All roms I ever flashed would be snappy for the first couple days then slow to a crawl after a month. This has brought this phone back to life and prevent me from having to flash all the time. I wasn't able to do the ZRAM disable since I don't think I have that settings, but I updated the min-free settings and have seen noticable improvements. Thanks!

What does this do exactly?
Will SD Card Read Ahead 2048 not reduce the life of the SD? (and by a lot since my current ROM was 200% less.)

No. In writing a lot over time can possibly reduce the life of the SD. I don't believe that reading will.

I use ROM Toolbox to benchmark. 2048 usually yields better results overall.
