[Q] swap on ace

Hi buddies ;p
I have one question...how can i enable swap partition on my ace?
I have kph rom + ext4 + CWM + cf-root 3.7
I try to use swapper ane swapper 2 app...
Swapper 2 doesn't work good...it's crashed on create a swap file
Swapper seems that he work well..create swap file well then i reboot my phone and it still doesnt work...on setcpu swap has 0kb...
Are there any ways for do it?

Get CF-Root Kernel b80, DarkTremor App2SD for CF-Root Kernel and A2SDGUI from Market for easy setup.

Using a SDcard with swap partition will only cause lags unless and until you have a class 6 or greater SDcard,
Also Having swap partition on sdcard is not good for the health of the SDcard has no. of read and writes increases dramatically

yeah i know that the health of our memory decreases but if i had a 6 class of sd this swap help me for performance my pda or not?
Is this useful?does 4th class is sufficient?
Hmm i have apps2sd and in the tweak manager i didn't selected "Dt: auto start" and i dont have a dtapps2sd script...so i have to install it?
Can i upgrade my kernel from b70 to b82?
btw: which kernel is the best b78-b80 or b82?For upgrade to b80 i have to flash this file CF-Root-S5830-v3.7-b80_boot.zip or i have to flash it with odin?I dont understund very well....

There are many 2.3.4 roms... gingerreal, flash... in this case use the latest cf-root
CF-Root-S5830-v3.7-b82.Just flash the zip. Does not suport swap or BLN for now.
Install also the updated ext4 Manager.

what is it bln?
Which is better b80 or b82?
If i install b80, swap start with him?
thx for replies ;p

BLN is button light notification. It uses your button lights as would LED of other phones work, which is to blink when you have message or missed call.
B82 doesn't support that nor does it support swap.

I had no problem using my class4 with swap partition, encountered no noticeable lag.
Had to remove it though before flashing KPO.

One thing to note: lower class SD card is probably going to perform better because the random access on lower class SD cards is better than Class 10. Class 10 is generally better throughput at the expense of random access. Since you should rarely be swapping, it's usually a waste of time. Better off using a RAM tweak such as Supercharger.

i upgraded to b80 but swap still doesn't work...why?

Did you make a swap partition on your SD Card?

how can i do it?

clockwork recovery -> advanced -> partition sd card

I'm using official CM 7.2 and also have the problem of low memory (damn; my older HTC Wildfire (v1) never had this issue; this older/slower budgetphone has much more memory on board)
I made a swappartition; it cannot be mounted as swappartition... by neither swapper2 or swapper.
Since i'm using S2E i actually wanted to use the internal memory of my phone for the swapfile (or tried that one too, cuz it's not being used when loading apps...) but i couldn't save my .SWP file over there. Also on my fat partition (1st partition on the sd card) i wasn't able to get my swapfile working... (it was being created, but that's all....)
When i was using the nightlies of CM 7 i was hoping this was an issue they would resolve when the final was released; as CM7 on my wildfire has no problem at all to use swapfiles...
Anyone info on how to get swapfiles when using CM7 (official)?

Droid 3 and Swap

Hi everyone... have a question... It's possible to enable swap support on our droids? and if it's how?. Because I'm tired of everytime a switch from one app to another it kills one of them. Thanks!

bump, after a long search it seems to be imposible because current kernel don't have have swap support and with a locked bootloader we can't change the stock kernel, i hope some day motorola unlock our droids bootloader or someone can do it . If i'm wrong please let me know. Thanks!

I activated a swap file on my Droid 3 using mkswap and swapon as root from the command line. The kernel recognized the swap space, but as soon as the phone ran out of memory and tried to swap something, it rebooted.
I'd be interested in hearing if anyone else has had a different result.

It suprised me that kernel recognize you the swap space...do you create swap file in your internal memory or a sd memory?
Edit: I tried this morning but i have the same results as you... as soons it starts to use virtual momery it rebooted.

edit: Well i play with swappines but same results as soon our device started to use swap it rebooted..perhaps someone with more knowlegde can do something about it...it would be great if someone can do it.

Like all file systems, support for swap must be coded in the kernel (it's not), or added by kernel modules . . . Which would have to be specifically compiled against OMAP4 source code, I think, to work. I'm not a programmer, so I can't help directly. See if whoever provided the community the tun.ko kernel module for D3 can whip us up a swap module. Still, our kernels are locked, so the swap.ko would have to be added to a /preinstall aka 2nd-init kernel. Maybe Hashcode can help?
BTW: this thread should be in development, not General, I think

I use swap all the time. For instance, currently my phone has 111M RAM free and is using 162M of swap.
I've created a swap partition on an SD card and use that, so no swap file.

Yes, please explain what you did to obtain Swap. The last Android device I had with functioning swap was the G1/HTC Dream, and we had swap because custom kernels had support for it an modules created the fs every time android booted. Whether a swap partition was created and mounted was up to the rooted user. I have used the makeswap and swapon commands with busybox from the command line and could not get the swap partition to show up in mount. Which address block did you use to create the partition? I tried /dev/mmcblk1p025 and 26 (sdcard and emmc?) and neither worked.
BTW: Many intelligent minds say swap in Android is useless since the Java/DalvikVM is so aggressive about reclaiming memory (just watch logcat to see that happening non-stop). You would have to swap to a device that is as fast as your secondary storage (meaning the 512mb of DDR2 installed in the XT862) in order to "beat" Dalvik's garbage collection and "augment" the natural AndroidOS memory management. One of the gifts of running bytecode in Java is that one does not usually address RAM directly (unless you jump out of Java with some C/C++ code), the OS is always handling your classes-to-registers allocation for you, the developer. In other words, it's Android's job to manage your memory, and if you ask the linux kernel and file system to cache registers to the comparatively "slow" sdcard (flashmem is slower than DRAM), you'll essentially be blocking Android's ability to handling your instructions, data, and files because it will then have to go pick up that data from a slow swap partition. When we were trying to push the G1's limits (which was delivered with a paltry 64mb of userdata space), swap made sense because the time it took to request stuff from swap was much slower than recreating threads out of compcache (compressed and old handles). 512mb is still relatively big for a device, and Android, like Linux, will always buffer most of your memory to make sure you don't run out of space for your apps. I am not a programmer so I may have messed up some of the finer points--but this is the gist of Android-vs-Swap as some see it.

Swap will have to be setup on the external sdcard, which is /dev/block/mmcblk0p
mmcblk0p1 - * would be the partitions

Exactly, setup a swap partition on an ext SD card, then swap on it. Never had a prob.
I don't really care about Android memory usage and management, I need swap because I run GNU/Linux in a chroot, and for that the measly 150M that the Droid 3 has free by default is useless...

I really like DROID 3 and would get it but 512 of RAM and locked bootloader are killing me. But I can't imagine a better device than this one if those two factors didn't count.
Please tell me that something can be done with ICS, low RAM and custom kernels?

ICS runs good and the only reason I tweak my memory settings is just because Words with Friends is a battery hog and so is FB sometimes. I never seem to run out of RAM.

If you like the keyboard, why not get a Droid 4?
Sent from my DROID3 using xda premium

Droid 4 doesn't support GSM networks and I am from Europe where most of the carriers are GSM and so is mine. Droid 3 xt862 is a global phone (both CDMA and GSM) and Milestone 3 xt860 - GSM only. Besides Droid/Milestone 3 looks much better than D4 as for me.

[Q] increase internal memory with CM7 rom

hi,
i am running CM 7.2.0 RC5.1 KANG on my galaxy mini.
after fighting myself through endless threads i still cannot find the answer to my question. or maybe i have missed something or it was too complicated for me to understand.
many of those memory increasing posts are only for stock roms.
and i want to increase it with cm7 on the phone. is that possible?
i intend to update to the latest official CM in the near future. would it be easier with a clean install?
please share some information ... i have only 20 MB left

Use any app2sd program you prefer.
Most famous and used are s2e, link2sd, etc
As i was on galaxy mini, i used mebiteks rc0 v0.7 cyanogenmod in combination with link2sd and a 512 mb extended partition. It worked flawless.
Just pic your choice and try.
TIP: Make a backup of your current rom. In case something goes wrong you can go back to last state.
Good luck.

thanks for the quick reply.
i am still a bit confused.
in some threads they write: don't use program X, others say never use program Y and some even say never ever use progam Z.
some members report bootloops, some get instant cancer or die right away.
any clues what works "best" with my rom or do i have to go via K.O. System?

What program works best depends on the rom you use.
I believe S2E works fine on that rom.

sorry, perhaps i didn't make myself clear enough.
i have only 5 apps installed (additionally to the cm7 apks)
the other 60+ programs are installed on the sd card.
my question was: how can i INCREASE the 178 mb ram on the galaxy mini.
let's say ... 1 GB ... that would be fine.
as i have mentioned before, those scripts or progs are available for stock rom only.

Practically speaking, you cannot increase the 178mb internal memory.. that is a hardware limitation.. what we can do instead is alter how android utilize the internal memory. If you want to see 1GB as your internal memory, amarullz and ungaze scripts can do that. You must have a 1GB sd-ext partition on your sdcard for you to use this scripts. Recommend amarullz though coz ungaze makes things laggy.. to know more and how to use these scripts, do a search in the dev section..

you go to samsung centre and blame it there...

First take a backup of ur sd card content .. As it will wipe of ur sd card !
Go into cwm - select sd card partition - select how much u want to increase ur internal memory-select swap value 64 mb -and then reboot
This is the easiest way to increase internal memory

Increase RAM using Swap File and Swap Partition

Followed the guide in the above link but can't get swap to work. Rom is 2.3.6 Stock Rooted and BusyBox installed. But keeps failing. Has anyone been successful with Swapper 2 on stock rooted firmware? Before anyone says don't bother or not worth it, I would like to say irrespective I would like to try and see for myself.

swap kills your sd card !!!! real fast !!!! killed mine!
though it did giv me some performance boost

Swap partition will be used as ram.
So, "n" no of read and write will happen depending upon the swapiness value.
It will spoil your memory card.
And another thing is your memory card shoud be very fast to maintain performance (higher class).

Kingston SD Cards come with a lifetime warranty so if it does kill it, they should replace it. It's a shame that you require cf-root because I don't like the fact that CF-Root changes the startup logo and add Clockwork Mod which my idea of stock is not. Is there any other ways?

Yes they do replace it.But many people dont have backups of their data so for them losing sd card is a real trouble.Now,No stock recovery works after rooting.It is unable to mount partitions so most of CWM flashable packages wont work.still,If you want to have stock recovery back then head to dev. section,find the thread for stock recovery and flash it.

Wooooow boy r u sure you're in the current time. Its 2012 now. . Jokes and no think about it, would it reasonable for a manufactury to do that? think about it in a bussines way. For the moment if you feel like you need more ram just create a swap partition. class 6 or above SD card is suggested and don't worry about the SD lifetime so much you r not gonna have the same phone or SD for like 20 years anyway. R u ? Let me know if you need help with partitioning your SD and I'd appreciate it if you press the thanks button. Also I have a swap partion on my SD its much better and I haven't ran into problems. Its true that it decreases the lifetime but it's not like what you think

Well I have replaced Kingston SD Cards in the past under manufacturer warranty without any problems and as for losing data, that is also not an issue for me thanks to dropbox and automatic camera uploader. As for other phones, the apps, contacts, etc are backed up by google so it is not a big of an issue as many are making it...well at least for me anyway. I just want to give it a go but at the same time I don't want to leave stock. Please don't ask me why as it is self preference and I have explained in other threads why I prefer stock over custom firmware and really do not wish to go into a debate regarding this.
You talk about a Swap Partition. I was under the impression for that a custom Kernal is required. As I am on stock, I would have thought that running the created swap file at boot should do the trick without having to partition a bit of the SD card to Linux Swap. Is that not the whole idea of the Swap File as opposed to a Swap partition?

Low memory with CronMod on CyanogenMod.

I have CyanogenMod 7.2 on my phone with CronMod memory mod. My internal memory shows that I still have 456 MB of space from my 758 MB ext4 partition. Yet phone show info that I have low storage space. Why?

Which script did you use?

That's really weird. It's not supposed to happen. Though I have had some issues like that, it's because you know some parts of the app stay in the internal memory of the phone, they have to be manually moved to the SD over time. Since it's a really small amount of storage that that part of the app takes, it really shouldn't be a problem. But since you have a lot of them installed, you're gonna have to manually move the apps to the SD.
Use Titanium Backup and batch move the heaviest apps you have to the SD and it'll work normally.

Sorry, I'm just having no luck getting the fixed IN2EXT4+ to work on an international galaxy ace. the script creates a file in the init.d folder, as opposed to the unfixed version, but it still doesn't mount or recognise the ext partition on the SD card. I've followed your guides very closely, I'm not sure what I'm doing wrong...
after each attempt, i start from scratch (clean ROM install), and yet I keep failing ;/
I partition using CWM recovery 5, so does that create an ext4 partition or 3/lower?
