I am currently running Cyanogen's latest. I have a 40MB Swap partition, however; I'm curious as to whether or not it has been activated or enabled automatically via some script within his build version? I have been using the application known as "Swapper" to perhaps utilize my partition, so far, I have noticed that it seems to "swap" properly...but is using a specific command what actually has to be done to initiate the swap feature and partition to be used?
I've read in several threads and message boards that have claimed to find utilizing Compcache w/ back_swapping was in fact more efficient or "better" if you will - than using the typical Linux-swap for your 3rd partition.
EX. - http://androidcommunity.com/forums/archive/index.php/t-22465.html
If there is a proper way to be sure that the partition is being used for swap, (i.e. - terminal commands, etc.) let me know. Any advice would be greatly appreciated. Thanks.
Bump, bump, bump, bump it up.
Come on guys. This stuff is considered important. I'm just in need of a little advanced feedback. Trust me, if there's anything I can do for you, I'd be willing to help and exchange information.
Thanks.
cyanogen's roms have compcache enabled by default if you don't have a userinit.sh file in /system/sd. If you do, then compcache will be disabled and u will have to manually enable it in the userinit.sh file.
To see if you have a swap, run "free" in adb shell or the terminal.
To see if you have compache enabled, run
rzscontrol /dev/block/ramzswap0 -s
from the shell.
If you are using swapper app, and you don't have a userinit.sh file, then you are most likely running both compcache and swap at the same time.
If you want to enable compcache with backing_swap, create a userinit.sh file and paste these lines into it. Then make sure to turn off the swapper app.
Code:
modprobe ramzswap;
rzscontrol /dev/block/ramzswap0 -i -b /dev/block/mmcblk0p3;
swapon /dev/block/ramzswap0;
Finally...

I've been eager to get some useful information from someone in the community who is familiar with these procedures. I appreciate your feedback. However, here is my current situation; as previously stated:
- I've been using the application called, "Swapper for Root Users."
- I double-checked the status of this so-called SWAP from the terminal emulator and the information is displayed as follows:
* After enter the command "FREE" *
Towards the bottom of the provided information there is:
SWAP: total - 24464 / used - 12244 / free - 12220
TOTAL: total - 122344 / used - 108736 / free - 13608
As for what I have altered under settings with that application - I did utilize a feature which claims that it allows the application to SELECT your Linux-swap partition, instead of creating a "momentary" swap section on either of the other two partitions of my SD card. I have "swappiness" set to 20 currently. My partition, as stated previously is 40MB as opposed to 32MB. I have had more positive experiences thus far...not to mention it was suggested by several other people amongst the community.
Is the possibility of Compcache and the actual Linux-swap operating at the same time necessarily be considered a bad thing? Perhaps having more of a negative affect as opposed to a positive affect? Finally, if you don't mind me asking...which would you suggest or personally recommend:
Compcache enabled with back_swapping
-OR-
Linux-swap enabled
Thanks man. This is about the most successful set of advice I've received in a few days. Hella props.
Bumpinator.
Sorry guys, just waiting on a detailed reply from this boss right here who has posted a pretty in-depth process on my dilemma.
As soon as I come to a decision, make the changes, and finalize the device alterations...I will close this. Thanks.
When CompCache is managing your swap settings, you can use backing swap OR Linux swap. If you look in the user.conf and in that androidcommunity thread you posted, they both say:
#
# linux swap can only be enabled if cc_backingswap_en is set to "0"
#
But you weren't asking that question and you probably knew it already?
Word on the Dream forum from most users is that CompCache with backing swap provides better performance than Linux Swap or CompCache without backing swap (and I also agree with this).
Personally I would not use 2 apps to write to swap files/partitions on your SD card at the same time. You should be minimising reads and writes to the sd card as much as possible to help speed things up.
There is a lot more discussion on Compcache in the dream section on this board, you can probably find your answers already rather than constantly bumping this thread.
Looks like you only have compcache enabled, as by default compcache sets up a 24meg swap.
did you create your linux swap correctly?
after you partition the sdcard. You still need to run
mkswap /dev/block/mmcblk0p3 from the terminal.
do a "ls /dev/block" from the term and make sure that the file mmcblk0p3 exists. If not, run mkswap.
I would personally either run compcache by itself, or with backing_swap, both are faster than a straight linux swap IMO.
As for swappiness, thats up to you. I run swappiness at 60 myself.
You can set it by putting this line in your userinit.sh
sysctl -w vm.swappiness=
put your swappiness value after the =

Thanks again bro. This is good stuff.
So, I ran the "ls /dev/block" to check out the status; here's what I got:
loop0 ------------ loop6 ---------------- mtdblock0 ------------ mtdblock6
loop1 ------------ loop7 ---------------- mtdblock1 ------------ ramzswap0
loop2 ------------ mmcblk0 ------------- mtdblock2 ------------ vold
loop3 ---------- mmcblk0p1 ---------- mtdblock3 ----------- (empty space)
loop4 ---------- mmcblk0p2 ----------- mtdblock4 ---------- (empty space)
loop5 ---------- mmcblk0p3 ----------- mtdblock5 ---------- (empty space)
Assuming that because I see the "mmcblk0p3" I did correctly partition the SD card. After all, I used GParted. Lol.
But for now, I think I'll be set with Compcache running by default on Cyanogen's build, with a Linux-swap partition being utilized as opposed to back_swap.
Is there any other suggestions you might have for me? Advice? Questions? Thanks again.
EDIT: I ran the command from the terminal:
# mkswap /dev/block/mmcblk0p3
Then this came up:
Setting up swapspace version 1, size = 40305664 bytes
Then I ran command:
# free
And I see that where it says SWAP, there is more "memory" all across the board.
As for setting the swappiness, isn't it set to 60 by default upon activation?
Also, the "userinit.sh" - I don't think I have even messed with that or have one for that matter.
[size=+1]Introduction[/size]
What is GenTop2?
GenTop2 is a full-fledged Gentoo Linux able to replace the original Motorola Webtop. It is faster, fully-customizable and gives you the power of a complete Linux system on a mobile phone. It is a peek into the future of mobile computing!
Thanks goes to kholk, who did the original GenTop, otherwise I would have long given up.
Why use Gentoo Linux as WebTop?
Programs are fully optimized for the ARMv7a CPU contained in the Atrix.
Thus the whole system is faster and more responsive.
No shackles put around the WebTop by Motorola.
You can install any program (which compiles on ARM).
All software (except X11) is fully up-to-date.
You remember old times with desktop computers having far slower CPUs and less RAM than your phone and you wonder what you can do with this pocket computer.
Why NOT use Gentoo Linux as WebTop?
Gentoo is huge because it must install all development files.
The system and all programs must be compiled on the phone. How crazy is that?
Firefox could not be built. But, there is a smaller replacement.
Why bother using a phone, when you already have a notebook?
Working and Installed Applications
X11 via WebTop or HDMI (with hdmi-hack)
Xfce4 with thunar file manager
midori web browser with Flash player
claws-mail client
audacious
evince (pdf viewer)
ssh daemon
rxvt terminal
aiw Android In-A-Window!
Sound output via Android media system.
All are very light-weight Linux applications perfect for a small system.
Not Working:
webtop-panel (system status bar on top)
non-flash video playback ?
Installable as binary packages:
firefox (renamed to Aurora due to trademark stuff), approx 30 MB.
thunderbird (renamed to Earlybird due to trademark stuff), approx 44 MB.
libreoffice, approx 250 MB.
abiword, pidgin, emacs, texlive,
and many more, drop a note for more wishes here. However KDE is just too large.
[size=+1]Installation Instructions[/size]
Prerequisites:
Motorola Atrix
[size=+2][highlight]BACKUP.[/highlight] This will break your device![/size]
Okay hopefully it won't. A full restore will of course overwrite the webtop.
root privileges.
unlocking is not necessary.
adb and Linux knowledge.
webtop2sd is not supported (!)
CM7 is NOT supported
GenTop2 Space Requirements, Disk Speeds and a Note About WebTop2SD
Gentoo is very large because packages contain all development files. This cannot easily be changed, therefore one must work around the space limitation of the /osh partition in some way.
I did some "disk" performance measurements using bonnie++ (see [1] for full info). Here the through-put results in short: /data (ext3) 20,800 KB/s read and 6,200 KB/s write, /sdcard (fat32) 21,500 KB/s read and 8,000 KB/s write, /sdcard-ext (ext3) 12,300 KB/s read and 4,200 KB/s write, /sdcard/loopback.img (ext3) 16,150 KB/s read and 4,400 KB/s write.
One way to go would be to require webtop2sd, however, GenTop2 does not support webtop2sd because the read/write speed of the internal sdcard is much faster than on the external sdcard. Thus I tried to install as much on the /osh partition as possible and move directories onto other partitions as necessary, leaving symlinks behind. WebTop2SD also requires dpkg for some reason, which Gentoo does not have.
Therefore, it's pretty unavoidable that you do some space management yourself.
I have decided to utilize the /preinstall partition for /var. I'm not fully sure that this partition is unused on every Atrix released, but I guess in most cases it contains only provider specific bloatware that people don't want anyhow. On my Atrix it contained some car racing game, which I find hilarious to play on a mobile phone.
Anyway, the /preinstall partition is 300 MB and perfect for /var if reformatted to support many small files. The /var/db/pkg/ directory contains lots and lots of small files describing the installed packages. See the installation instruction for the mkfs line.
I also decided to require some extra ext3 partition for further program, data and portage files. It is needed anyhow to install further programs, which is what most people want to do. The /data partition would be the obvious choice and for that reason the first GenTop2 put files in /data/osh/. However, /home/ is also on /data by default and it gets pretty annoying when your home directory is full.
The only alternative to /data is either a partition on an external sd-card or a loopback mounted file-partition on /sdcard/, both are not as fast as /data (/cache cannot be used as it must be wipeable). So there really isn't much choice left except for external storage.
The main GenTop2 tarball puts 630 MB in /osh (leaving 145 MB free) and 178 MB in /preinstall (with 150 MB free), which must be mkfs formatted.
The portage GenTop2 tarball puts 1460 MB into /mnt/gentoo/ of which 475 MB are data files from /osh/usr/ and 810 MB are the portage tree.
[size=+1]Steps to install GenTop2:[/size]
There are some complications involved when using faux123's kernel, because it only contains ext4 filesystem modules and explicit mounting of ext3 will fail. The ext4 module will however mount ext3 filesystem without problems.
use adb shell and get root:
Code:
$ su
# cd /osh
# mv etc etcx
# reboot
Reboot. The above will disable the webtop.
Download http://kristallsturm.de/GenTop2/GenTop2-20120509.tar.gz (275MB) and put it onto /sdcard via USB or adb push.
use adb shell to overwrite the existing WebTop:
Code:
(first we delete /osh)
# cd /
# ls bin
bin: No such file or directory
(this tests whether the old webtop is disabled)
# rm -r osh/*
# ls osh
(should be empty)
(next we disable and reformat /preinstall)
# mount -o remount,rw /dev/block/mmcblk0p12 /system
# mv /system/bin/load_pia.sh /system/bin/load_pia.sh.disabled
# umount /preinstall
(depending on your ROM this might fail. ignore this problem if the following format works)
# mke2fs -m 0 -i 2048 -j /dev/block/mmcblk0p17
# mount -t ext3 /dev/block/mmcblk0p17 /preinstall
(for faux kernel: replace ext3 -> ext4 in above line)
(now we unpack the main tarball)
# df
(/osh and /preinstall should be almost empty)
# cd /
# tar xvzf /sdcard/GenTop2-20120509.tar.gz
# sync
(begin extra for faux kernel: we change ext3 -> ext4)
# sed -i s/ext3/ext4/ /osh/ubuntu.sh
(end extra for faux kernel)
# sync
# reboot
Once rebooted you will get an X11 login on the HDMI connection or you can access the phone via ssh.
Account Passwords:
root / atrix
adas / atrix
To make GenTop2 more useful and to compile/install further packages you currently must have an external sd-card (or someone must devise a method to use a loopback device).
I have partitioned my external sdcard using a desktop computer into the following two partitions:
/dev/block/mmcblk1p1 (remainder)
/dev/block/mmcblk1p2 (4.0 GB, formatted ext3)
Advanced: (Actually most of this stuff is advanced.) You can also use the new GenTop to partition the external sd-card. Open a terminal, and use something along the lines of:
Code:
# fdisk /dev/block/mmcblk1
(partition it, see further description of fdisk on the net)
# mkfs.ext3 -m0 /dev/block/mmcblk1p2
The boot-up script /osh/ubuntu.sh will mount /dev/block/mmcblk1p2 to /mnt/gentoo. This place is referenced by /usr/portage, /var/tmp and /preinstall/usr and will enable emerge if you install the second GenTop2-portage-20120509.tar.bz2 tarball.
Download http://kristallsturm.de/GenTop2/GenTop2-20120509-portage.tar.bz2 (124MB) to /sdcard/ using any method.
Use adb shell or a terminal on the desktop
Code:
$ su
# cd /
# tar xvjf /sdcard/GenTop2-20120509-portage.tar.bz2
Note: If you trust your network connection, you can also download and unpack simultaneously (without saving) it using:
Code:
$ su
# cd /
# wget -O - http://kristallsturm.de/GenTop2/GenTop2-20120509-portage.tar.bz2 | tar xvj
[size=+1]Installing further software[/size]
How do I install applications in Gentoo?
- Read http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=2&chap=1
- Read http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=3
I have set up a portage overlay "atrix-overlay" which unmasks many packages and includes some custom patches required for compilation on arm. It is included in the main tarball and automatically synced alongside "emerge --sync". Most updates will now be performed via this overlay.
See https://github.com/gendol/atrix-overlay for details.
Furthermore, for large binary packages like firefox, thunderbird and libreoffice I have set up a binary package repository with the same USE flags as the atrix-overlay. These are built using cross-compilation on my desktop computer.
See http://kristallsturm.de/GenTop2/packages/
To force installation from binary packages use emerge -G <package>. See the list of "Installable as binary packages" above.
[size=+1]Miscellaneous Questions[/size]
Why no thumb instructions?
- I did a speed test of cryptography functions and thumb instructions were approximately 10% slower than usual ARM code.
Where was GenTop2 compiled?
- Most of the system was fully compiled on my own Atrix. Larger binary packages are compiled on my desktop using cross-compiling.
Why is X11 not up-to-date?
- The only xorg driver I could get working is the one on the original Webtop, and that requires an older version of X11.
Why is udevd not running?
- If you look at logcat there are lots of the following messages, some of which are due to udevd. Disabling udevd reduces (but does not eliminate) these messages and probably also some unnecessary background process that draws battery.
NetlinkEvent: NetlinkEvent::FindParam(): Parameter 'UDEV_LOG' not found
NetlinkListener: ignoring non-kernel netlink multicast message
NetlinkListener: ignoring non-kernel netlink multicast message
[size=+1]Reinstalling the old WebTop[/size]
Some people on the forums struggled to reinstall the old webtop for some reason. It shouldn't be that difficult and I created a tarball of the original Webtop WT-1.2.0-133_38. These instructions were not tested by me:
Download http://kristallsturm.de/GenTop2/WT-1.2.0-133_38.tar.gz to /sdcard/ using any method.
Use adb shell or a terminal to disable mounting of webtop:
Code:
$ su
# cd /osh
# mv etc etcx
# reboot
Use adb shell to unpack original tarball into /osh:
Code:
# cd /
# ls bin
bin: No such file or directory
(this tests whether the webtop is disabled)
# rm -r osh/*
# ls osh
(empty)
# cd /
# /sdcard/WT-1.2.0-133_38.tar.gz
# sync
# reboot

It is a good job. I try this. Thank you.
This is a very agressive aproach. /osh dose have some Moto magic sauce in it. How well can you drive the screnn with a stock X system? Most of the cutesy features from WT I can live w/o, but the "phone"app really is usefull. Seams like this would be worth the effort to figure out.
If I was using a less "pure" setup (spinning up X and the phone app in Motos osh) then bringimng up the desktop in Gentoo, how would that compare to oither the same concept with other distros?
Please post on. I think this is the first time somebidy has run a non /osh X. Would love to see if it really can be done.

Thanks for pointing that out. Yes, the approach is radical, but not as aggressive as you may think. All the "magic sauce" in /osh lives in /osr/usr/local/ and all of that is retained. The only problem is that some dynamic link libraries are missing, but most of these problems can be fixed.
They actually had to be fixed because the GenTop2 does need to send some magic signals to Moto's PortalApp/DockService to work correctly. This is done using the /usr/local/bin/rmtest tool via the "fbcp" instance of dbus.
Other than /osh/usr/local/, /osh is really just Debian.
With the phone app, you mean the green phone button? I just tested that, it can be added. The phone button is nothing but a .desktop mime file, which calls one of the magic apps /usr/local/bin/androidlauncher. And it popups up in the aiw display.
I even tested the HD Media Center laucher and that too worked without problems. That really should be included in the next GenTop2 tarball.

I guess I don't understand what you mean with a non /osh X. GenTop2 does run X11 and you really need to replace the system libaries to get a well-working Gentoo.

Great job! Does this work with cm rom's aswell or only with blur based ones? As another fact, we could use distcc or crosscompile distcc to compile most of the stuff, actually even a crosscompile binhost would be doable for several packages. One more thing, we could probably use an .img file on the internal sdcard partition, that would be ext3/4 formatted instead of using the external sdcard (but probably its better and safer to sue the external card, due to the flash wear)
edit: so i tried it on my atrix with nottachtrix rom installed, it starts fine and seems to work rather well, i only saw two to me rather annoying bugs:
1. somehow the X server thinks that my tv (1080p lg) has a virtual size of 1366x768 and will not allow to use the 1920x1080 resolutions that are in the TV's EDID and that the system puts into the xorg.conf file aswell as it shows in the Xorg.0.log
2. the atrix's screen stays on all the time in the "normal mode" and if one uses the mouse on the gentop its moving and functioning on the atrix's screen aswell (ie you can launch apps by accident with the mouse in android)
I do not know if these are issues with nottachtrix or something else, but for me on the "normal webtop" 1080p worked on this same TV.
here the xorg log: http://dl.dropbox.com/u/24268926/Xorg.0.log
Really nice, installing it right now!
Does flash work on Midori?
I don't know about CM7, you'll have to try to replace the Linux system like moto does it.
The X11 screen size defaults to WebTop resolution 1366x768, but you can change that to 1920x1080 by editing /etc/X11/xorg.conf. The first thing to try is to comment out all Modelines and let EDID detection do the work. But for that a monitor must be present, so you need to Zap (Ctrl+Alt+Bckspace) your X, and that brings up the dual input problem.
I also use nottach's ROM. The dual input problem happens when something in motorola's magic communication goes wrong. I have not been able to figure out how in particular moto disables input on the touchscreen. For me it works most of the time. I also have all the Modelines in xorg.conf enabled, because they fit my monitor.
I didnt really focus on Flash, yet. But as it works on the original Webtop, you should just be able to copy the plugin files.

Can't get Midori working .. Got network (via ping), but no web browsing
EDIT: Solved by disabling proxy settings inside Midori
i haven't run gentoo in over 10 years but this is tempting!!!!!

1) After the reboot i used
adb shell
# tar xvzf /sdcard/GenTop2-portage-20120424.tar.bz2
but it gave me an error, am i using the correct command or i should use something else?
Yes. The touchpad thingy is also an open end. I have no idea why it doesnt come up. The GenTop2 tries to do everything in the same way as the original one, but for some reason that doesnt appear.
I guess the touchpad is some Android program part of DockService or PortalApp, which drive the Webtop switch. But I havent debugged how to activate it.
@snik38
To extract a .tar.bz2 you use tar xvjf ...

three items one that caused some grief, but other than that this has lots of cool potential!
I have a stock rom with root.
1. resolution was pretty screwed up. I did try to adjust the resolution, but it was locked into one setting.
2. flash isnt installed on the browser so many websites where disabled.
3. I could not get AIW to start.
I see you answered #1 in a previous post. But I think all three of those items are minimum requirements to replace webtop. BTW great job again! Its seemed much faster than the webtop app.
2. Try to copy the flashplugin from original webtop(not sure if it works with midori)
3. aiw works fine try to reboot the phone
Took me a while to get this all running, but it's great now it is. Have this over Nottachtrix 1.3.1. Everything installed and works fine!
Cheers!
When my phone turns on and gets to the preparing sd, it takes forever. Does this happen to anyone else?
anyone tried to emerge chrome/chromium?

Hi,
REMEMBER
FIRST OF ALL, do a Nandroid backup, as well as a backup of your sd-card content !
You're doing this at your very own risk, I'm not to be held responsible if something goes wrong
Now that said, let's get going
In case somebody wants to check it out, here is the swap activation script I wrote (attached) as well as explanations on how to make it all work :
1) Partition your sd-card (Minitool Partition Wizard, 4ext, CWM...)
2) Boot your system with the partitionned sd-card
3) If necessary customize the 99swap script (attached to this post) and then put it onto your sd-card's root folder, you'll need it while executing the commands in step 4.
4) Open a terminal and type the following
NB: Change "mkswap /dev/block/mmcblk0p3" accordingly to point to the swap partition you've created in step 1.
5) Reboot your phone, start a terminal again and type free, you'll need to see something different than 0 in your swap line, look at the attached print-screen
Swappiness will be set to 50 by the script, which is a rather conservative swap use, made sense to me since SD-swap is slower than ram, better not to use it too agressively. Feel free to experiment with the swappiness variable in the script (values between 0 and 100, 0 meaning "try not to swap", 100 meaning "try to swap all the time")
If you want to try and have a question, just let me know !

Hi JP,
This is a gem of a post! Thanks alot for the script and the detailed breakdown. Before I get into it though, I must warn you that I am more of a beginner with no coding/scripting experience (I don't know how to use adb or anything)...
Here's what I'm trying to do: I'm trying to activate hard-swap on my hd2 (currently) running the ParanoidAndroid by Xylograph. I've created 3 partitions on my 16gb class 6 sd card: first, fat32 (32k cluster), next, 1GB ext2 (default), 500MB swap.
Procedure:
1. I extracted the script and copied it directly to system/etc/init.d folder of the Rom (I looked at the terminal commands you posted and the first few lines looked like copying the file from the sd root to the init.d folder (it was just a guess though), so I figured might as well put it into the rom before I flash it)
2. Flashed the rom
3. To activate it, I typed the following into the terminal:
su
mount -o remount,rw /system
mkswap /dev/block/mmcblk0p3
mount -o remount,ro /system
exit
after the mkswap command, I did get an activation notification that a certain amount was assigned to swap. But my celebrations were cut short after I rebooted and used the free command to check. The entire swap row still read 0.
I was wondering if you can point me in the right direction... thanks!
Also, is there a way to create a cwm flashable version?

In fact you understood correctly that is was about copying the file to init.d.
By the way, these commands do the following :
mount -o remount,rw /system - Mount system partition in read-write
mount -o remount,ro /system - Mount system partition in read-only
So to format the swap partition "mkswap /dev/block/mmcblk0p3" there was no need for it, but it didn't harm in any way, so you're fine there
I guess what is missing is the "chmod 755 /system/etc/init.d/99swap" command which will set the correct file access to the script so it can get executed at boot.
You might do the following in a terminal :
su
mount -o remount,rw /system
chmod 755 /system/etc/init.d/99swap
mount -o remount,ro /system
exit
It should be fine then.
Alternatively you could set the rights with your file explorer (in root explorer mode), they must be "rwxr-xr-x" (which is Read-Write-Execute, Read-Execute, Read-Execute), most file-manager will allow you to do that as well.
I've been working on the script variant for htc Sensation, it is more advanced, dynamic so it can find the swap partition by itself.
I'll make a CWM flashable as soon as I get to it that will handle everything except partitioning the SD card, obviously, for both devices.
As soon as I'm done I'll post the HD2 version here as well (very little change, between both devices, just the access path to the sd-card partitons to change (=1 line in the script).
JP.
Edit ------------------------------------------------
I just reread your post, if in fact you put it into the ROM zipfile, then file access should be correct !?
Could you post the following file (if it exists) :
/data/swap.0.log ?

Hi JP
You are incredibly helpful and I appreciate it!
I finally got some time off and tried out what you mentioned... but to no avail. I applied the necessary permissions through the terminal (chmod 755) as well as through the root browser, but it was still the same. After that I even retried the terminal commands, and included the "chown 0:2000...", but that didn't work either...
... and then I saw your post update...
About that, i just typed it into the terminal, and I got "not found".
Was that what I was supposed to do?

Hi,
You're welcome
The file '/data/swap.0.log' is a text-file containing info on the execution of the script...
If it's not there, then the script didn't run at all...
I should have a little time later today, will try to make the CWM flashable solution for you, should be a no fuss solution, as long as the sd-card has a swap partition
How did you partition the card ? CWM ?

Mine was huge at the time, was on of the first to have such a big one, even partitioned it into 3 since it was just too big And it was an external device, the size of a pizza-box (it was en Atari Megafile 60, I still have it !!).

Hi JP, once you told me it was the address to the file, i just navigated there using my explorer and lo and behold!, there it was (attached). If you must know, in my earlier post, the idiot in me just typed it in the terminal and the terminal replied not found.
I made my partition using freeware called Minitool partition wizard. Is 500mb too big for swap in your opinion? I was thinking of compensating for zram, and hence the size... thanks for your speedy responses...

Hmm ... strange, the content of the file looks like a logcat ?! Not what I was expecting to see
Give me a little hour, and I think I should be done with the flashable hard-swap and we'll go from there
Minitool is excellent, but did you pay attention to only create "primary" partition ? If it is a logical partition it won't work...
Can you insert your SD card into your card reader, start Minitool an post a print screen of it ?
JP.
EDIT :
About size ... I believe 256Mb is enough, even read somewhere t shouldn't be more than 256, but I think there was no specific reason given.

Here we go...
Minitool image attached... I typically pay attention to the partition type and made sure both of them were primary
About the logcat, I suspect you're right... I was trying to do one from my pc for the first time using adb and tried the only few commands I know (mkswap...), I think that's what you saw then...
Incidentally, do you feel if I reduce the swap size, the script has a better chance at surviving the boot?

I have 512mb partition and it worked without problems as I mentioned earlier so I think that opposite to the "size does matter" in this case it doesn't plus I used it with zram from marc1706.

Hi triggaz, are you using the built in zram on Para1.1a? Or have you applied a script from elsewhere? I enabled the built-in zram, but get a "not found" reply when i try zram_stats in the terminal. Can you tell me how you got zram working? thanks...

I flashed this and then used the compcashe options in Paranoid (set to 26%)
Hello everybody,
I thought that ICS was a little bit slow on my SGS+ so I tried to tweak it.
This is when I came across the option compcache in the settings -> performance menu.
Only I found this option isn't w orking yet in arco's alpha 3 build, or isn't working anymore.
Either way I found out that zram0 is present on the device, so I created a little script with which you can set-up Zram.
Just put it somewhere you can browse to with Terminal Emulator.
Also make sure it's permissions are set to rwx-r-x-r-x.
After you set the permissions right, just execute with: ./zram start
Or if you want to stop the swapping again just give in ./zram stop
This is the code for the script:
#!/system/bin/sh
#
# Zram manager
# koudumrulez{at}gmail.com (PsychoGame)
case "$1" in
start)
echo 3 > /proc/sys/vm/drop_caches
echo 30 > /proc/sys/vm/swappiness
# get the amount of memory in the machine
mem_total_kb=$(grep MemTotal /proc/meminfo | grep -E -o '[[:digit:]]+')
mem_total=$((0,25 * mem_total_kb * 1024))
# initialize the devices
echo $((mem_total)) > /sys/block/zram0/disksize
# Creating swap filesystem
mkswap /dev/block/zram0
# Switch the swap on
swapon /dev/block/zram0
;;
stop)
# Switching off swap
swapoff /dev/block/zram0
;;
*)
echo "Usage: $0 {start|stop}"
esac
exit 0
You can just call the file zram, and then copy it on you're device for example you're SD.
I only used this script on ALPHA3 build. Maybe it works on others as well, but that's at you're own responsibility.
Greetings Psycho Game
Here I'am again.
There's been a little error from my side.
If you put this file on you're SD-Card you can't set the permissions right.
What I did was putting the file in /system/bin, so the full path would be /system/bin/zram.
I did this with ES File Manager, but you're free to use whatever file manager you like.
After this make sure the permissions are set to rwx-r-x-r-x in the file manager, or in the terminal you can do a "chmod 755 /system/bin/zram" without quotes.
The zram is now useable through executing the command: "/system/bin/zram start or stop".
You can also choose to mount the zram automatically with booting.
In this case you have to make a file called userinit.sh in the folder "/data/local/"
This file needs the following content:
#!/system/bin/sh
/system/bin/zram start
I also set the permissions of this file to 755 with "chmod 755 /data/local/userinit.sh" but I'm not sure if this is neccesary. Anyway it works.
Hopefully somebody can use this script as well. If you do, please leave a comment. Also if you have questions feel free to ask. I will keep an eye on this post.
And the question if this will work on Alpha 4, yes it does.
Greetings,
Psycho Game
Hi Psycho,
thanks for your effort.
I also saw that zRam is indeed not working on the latest Alpha 6 (i use the Galxy W / i8150 Build).
I had a look at your script and some other sources and enabled zRam on my deivce for testing purposes.
My conclucsion so far is, that there seems so be some major problem of interference with an other memory management policy.
Independent from the Size and Swapiness configuration - there is something going wrong hier i think
I watched the systems memory stats through proc/meminfo and free. Once the system is out of fresh memory, it begins swapping. zRam swap then getfs filled up quickly. Now the system gets extremely slow, i also had two restarts (likely in cause of some kernel panics from acute memory problems).
Will be difficult to track down the problem, my guessings so far:
- Interference with LMK, as it only indirectly knows about zRam
- Some kind of io block size might have been set to a bad value for the zram device
- CPU-load through compression simply much to high (unlikely, but have not checked it yet)
.. and plenty other possibilites
ATM, its definitely only a huge decrease in performance for me. What was your experience?
From the technical specs, i guess zRam should behave much better, so i really guess theres going something wrong.
Guess i found a possible reason for the bad performance.
I will write more details when i have the time to.
Just tried the above script on CM9 (build 0814) for Galaxy Exhibit 4G (a sister phone of Galaxy W as I understand it). I ran the script in the Terminal. Initially the performance became very bad after a period of time (especially after opened many apps). It almost looked like zRam made it worse once it got used for some storage amount. However, after I changed mem_total_kb from MemTotal to MemFree, and removed 0,15 for mem_total, the horrible slow down seemed to disappeared (even after I opened 5 apps at the same time).
any further refinements of this script?
I try this http://forum.xda-developers.com/showthread.php?t=1821071&highlight=swap and it's work, all is OK, on 481, enabling swap(file) failed.

How do you check whether it works or not? *I'm noob btw, so don't be too harsh on me.
At my device:
The starting without swapper2, when I type free, the swap is not at zero as the tutorial.
After activating swapper2 *following the tutorial
The total swap file is also not the same as the swap file setting when I type free at terminal emulator.
--edit--
The terminal free swap file status increased 30MB.
So maybe it really works. I'm noob so I don't really knows.
To check swap and memory, i use meminfo by Johannes Zweng on the market, you can view meminfo and swap, very handy.
I disable physical swap with swapper 2, but i let zram active, with 60Mo ram and 60% swapiness. Maybe it's a placebo effect, but the phone seems more responsive when switching apps. of course, there is no miracle, if you play memory hog games like Asphalt 6, when you end the game, there is likely a home restart.
I try 80Mo but this seems to much, you can also play with swapiness, but for me 60% is good, the more the percentage, the more the swapping.
I known It's looks strange to use ram to swap from ram, but zram compress ram, so maybe this let you with more free ram
Since i'm on a stock kernel without init.d support, i use Script Manager with a script and start on boot. I use this script, it's a little different than the one in the thread, i had swapoff command.
#!/system/bin/sh
sysctl -w vm.swappiness=60
swapoff /dev/block/zram0
echo '1' > /sys/block/zram0/reset
echo $((60*1024*1024)) > /sys/block/zram0/disksize
mkswap /dev/block/zram0
swapon /dev/block/zram0
