Setting up swappiness? - G1 Q&A, Help & Troubleshooting

im running the latest Drizzys hero and i need to set up my swap can anybody put the commands please and what do i use to set it up?....i'm running it o a G1 thanks in advance!!

Do you already have the third partition? If you do, then you can do this in terminal:
Code:
echo 80 > /proc/sys/vm/swappiness
Where "80" is my value for swappiness

You won't get any varification you'll just recieve no errors. If you want to check the swappiness
Code:
su
vi /system/bin/user.conf
look for cc_swappiness= [] <-- That's what you're swappiness is at.

Got it working ^^

[SCRIPT] Toggle JIT on/off (updated instructions)

This will NOT work in CM5.0b4 as JIT has been disabled entirely
It seems like a lot of people are constantly pulling/editing/pushing build.conf in order to turn JIT on and off, so I threw together a short script to toggle it on and off.
It's nothing elaborate, but it gets the job done. This is meant to work with the build.prop that comes stock with cyanogenmod 5.0b2 but will most likely work with other build.props that have JIT.
Steps to run the script:
1) Download jit.txt, rename it jit.sh
2) If you downloaded from your computer, run "adb push jit.sh /sdcard" or mount your device and copy to your sdcard.
3) In terminal on Nexus One:
$ su
# sh /sdcard/jit.sh
JIT toggled ON
JIT enabled upon reboot
#
You can also set it up in GScript or GScript Lite so you can add an icon on your homescreen to toggle JIT more easily:
1) From command line: mv /sdcard/jit.sh /sdcard/gscript/jit.sh
2) Open GScript
3) Go to Menu->Add Script
4) Go to "Load file"
5) Select jit.sh
Then to make an icon on your homescreen:
1) Long press homescreen
2) Select Shortcuts
3) Select GScript(Lite)
4) Select jit
You must reboot for the changes to take effect after running the script. If you prefer, simply put "reboot" (without quotes) on it's own line at the end of the script and it will reboot automatically. Only do this after you have confirmed that the script works for you.
If you are using Windows, make sure you use the attached jit.txt rather than copying the code from this post. Copying/pasting the code will not work because of Windows CR/LF line breaks.
Code:
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
if grep -q fast /system/build.prop ; then
sed -i s/=int:fast/=int:jit/ /system/build.prop
echo "JIT toggled ON"
echo "JIT enabled upon reboot"
else
sed -i s/=int:jit/=int:fast/ /system/build.prop
echo "JIT toggled OFF"
echo "JIT disabled upon reboot"
fi
exit

Simply push the script to your phone (sdcard, or wherever you please) and run it. For example, put the quoted text into a file called jit.sh, push it to the root of your sdcard, and run "sh /sdcard/jit.sh" from a terminal. You can also set it up in GScript or GScript Lite so you can add an icon on your homescreen to toggle JIT more easily.
You must reboot for the changes to take effect.

Nice - been looking for just this, thanks. As a bit of a n00b, any idea why this doesn't seem to run in GScript Lite? I get the SU request OK, but then nothing - don't see the echo'd text at all, nowt. Running CM5b2 .29 kernel.
Ive installed pauls modaco patch wil this turn jlt off? its annoying me
Thanks for this script !
I just pull, nano, and push it back.
I don't think It's 100% stable.
push/pull? Shoot, I just use vi on build.prop from betterterminal. Don't have to mess with adb at all
Since you need to reboot anyway, couldn't we just put "reboot" in place of "exit"? I'm assuming that's not part of the script to save, since you have "fi" at the end of it. Personally, what I did is save 2 versions of build.prop to my sdcard and then built gscripts to swap 'em out. lol A little more crude, but just as effective.
when i try to run the jit.sh file in terminal i get:
failed: no such file or directoryk3 on /system : not found
sdcard/jit.sh : 13: syntax error: end of file unexpected (expecting 'then")
am i completely retarded?

Yeah, I had the same problem. Remove the su request from superuser.apk. Then, run any script that requires root. Click remember, and allow. It will not work at this point. Back out to the homescreen with the back button, then go back into GScript Lite and run it again. It should work this time.

Not sure. I would assume so, never seen the build.prop that's used but I don't see why it would be any different.

That would be more efficient, but I just enjoy clicking my icon a few times and toggling it on and off Don't ask me why.

Proceed to edit (man vi, google vi). Bit of a pain in the ass though if you switch back and forth frequently.

Don't forget, you need to remount /system as rw also. it is a tiny bit of a pain, but I don't see much of a reason to switch back and forth all the time. Thus far I have yet to have any problems with JIT.

The only time I consistently have problems with JIT is when tethering. Otherwise, I have yet to have any issues. I tether frequently, hence the script.
BTW, thanks for Apps2SD(2) and OpenOverclocker. They were very helpful to me at one point.

Hm, strange. I can't duplicate this error. The steps I take are as follows:
1) Cut/paste the quoted code in the original post and save it in a document called jit.sh
2) On computer, adb push jit.sh /sdcard
3) In terminal on Nexus One:
$ cd sdcard
$ su
# sh jit.sh
JIT toggled ON
JIT enabled upon reboot
#
I'm sorry I can't be more help, but I'm not sure why you'd see that error.

Ok, I didn't do the whole adb push thing, I just copied it to my SDcard root from windows. Is that the problem?

Ah, it's the line breaks. Windows uses a pair of CR and LF characters to terminate lines. Unix based system use an LF character only.
You can get a utility to convert the line breaks to unix style line breaks. I'm sure it will come in handy. I'll also upload the jit.sh with proper line breaks to the original post.

Just tried pushing it to the sdcard, that went thru ok.
Still cant get it to run, same error. I've tried your command in the OP, and the what you wrote out a couple posts up. Same error on each one.

If you are on Kings rom, it may be running already.
Type #free in terminal and see if it shows swap.

It definitely depends on the rom. Some King roms he has a script you run. Other roms, all you do is go to Spare Parts and set what you want. It may be best to ask in the thread for that rom.
I remembered using this when I used CM:
http://forum.xda-developers.com/showthread.php?t=581328&highlight=swap
Enable swap
I used the method to enable swap in Linux on this and it worked fine on Cyanogen and Super-D.
I used Amon_RA Recovery 1.52 to partition my SDCARD and the new recovery lets you choose the size of your partitions.
so I created a 256MB Swap.
from a console/terminal do the following after creating your swap partition the size you want it:
1. mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system (makes system dir writable)
2. mkswap /dev/block/mmcblk0p3 (formats the swap partition on SD with swap format)
3. vi /system/etc/init.d/05userinit (make a new line at the bottom and add "swapon -a" with out the quotes this forced the swap to mount on boot if it is disabled in a kernel)
4. vi /system/etc/fstab (add a line that says "/dev/block/mmcblk0p3 swap swap" with out the quotes)
5. reboot
Hope you know how to use vi editor If not google it. "I" is insert mode and push track ball and hit 1 at the same time and that will esc you to command mode, in command mode do a :wq! and hit enter and that will save the file.
This works on all roms i have run into and no matter what others say it does help the performance.
I can make it easier (short of putting this in a script). Type each line in order and hit enter after each.
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
mkswap /dev/block/mmcblk0p3
echo "swapon -a" >> /system/etc/init.d/05userinit
echo "/dev/block/mmcblk0p3 swap swap" >> /system/etc/fstab
reboot

EDIT:
for stock 2.2.1, customroms should use their 2nd init (CM7 HowTo):
move original file:

mv /system/bin/mot_boot_mode /system/bin/mot_boot_mode.bin
create file /system/bin/mot_boot_mode:
Code:
#!/system/bin/sh
export PATH=/system/bin:$PATH
mot_boot_mode.bin

How to apply this?
Sent from my Milestone using XDA App
to apply this fix you hafe to (as root or in OR)
if /system is readonly:
Code:
mount -o rw,remount /system
then edit /system/etc/rootfs/init.mapphone_umts.rc and add
Code:
# Set OMAP DSS update_mode to 1 (auto) to get rid of the DSI errors
write /sys/devices/omapdss/display0/update_mode 1
after these lines
Code:
# Enable panic on softlockup
write /proc/sys/kernel/softlockup_panic 1
reboot Milestone
Maybe it should be
mount -o ro,remount /dev/block/mtdblock6 /system
Hm, there is no directory rootfs in /system/etc/ ... Have you tried what you are writing here? Maybe "rootfs" refers to the root dir "/" and the file to edit is "/init.mapphone_umts.rc".
You don't need a reboot.
echo 1 > /sys/devices/omapdss/display0/update_mode

(I presume that's what that command in the rc file does, right?)
But make the changes to the rc file as well, so the above action is performed on subsequant boots.
as it's on nadlabaks github for cyanogenmod4milestone (CM7) it might differ from the way to do in official froyo. but IanTesters way should do the same

Seems to be the case. But since I'm not able to edit /init.mapphone_umts.rc (that's the reason why there is an extra dir for this in cyanogenmod), how am I supposed to implement this fix in the official froyo?
Done on CM6.
Yesterday I was browsing the system folders and found this file, full of customizable options, now I know that it's useful.

For stock Froyo roms, i applied VR and then ran AOR, connected phone to pc and used the following commands in command prompt.
adb devices ( should show your device as connected )
adb shell
echo 1 > /sys/devices/omapdss/display0/update_mode
reboot
Upon reboot, i did not find any errors in dmesg which i usually find.
Can someone with more knowledge than me confirm if this is ok?
I know that can be a noobish question but what VR stands for ?

VR --> Vulnerable recovery
AOR --> Androidiani openrecovery
I had to do it because adb was not recognising my phone while in the stock recovery menu.
Once i ran AOR, adb recognised my phone to be in recovery mode.
I make this "echo 1 > /sys/devices/omapdss/display0/update_mode" from terminal emulator and after reboot its back to "2" it must be done form adb in AOR ?
it has to be done on or after any boot.
I edited the 1st post to include the changes to do on stock 2.2.1

Looks like it loses it during reboot, so it could be added to the init.rc file as well. I am not sure, that's why i asked with someone more knowledge to confirm this.
Anyone?
I have Autostart app and i make autostart.sh with that command and now its start every system boot.
In home i will try that ColdSphinX method and see what happend
@fuggii it's not my method, it's just a mot_boot_mode hack so you don't need any app and the fix get's applyed as early as we can
I think this should work but I copied all of this https://github.com/nadlabak/android...b50/prebuilt/etc/rootfs/init.mapphone_umts.rc
And used that as init.mapphone_umts.rc
Hey the OP needs updating....
It's missing the 1

i had install the overclock at default 691MHZ...
when i reboot it to restart the phone i see there have some changes 600to691MHZ..
but after few minutes,it will reduce to maximum 600MHZ
it is normal??or not normal?
only when i switch on the phone it will maximum 691MHZ....after will back to max600..
You have to enable "Set on boot" option.

Did you already try by editing build.prop and put this line on it?

if you already has a line with echo "XXX" > /proc/x8oc or such a thing, just edit and change its value to 24 to give it a try. Or you may use setcpu also
the instruction there state put a line insmod /system/lib/modules/x8oc.ko # x8 overclock at the begining in /system/etc/hw_config.sh
does not adjust any system/buil.prop ...
so u mean add 1 line echo x24 > /proc/x8oc this code?

are you using swapper2 app? please specify more info on your problem
You dont need to use an app to get swap. I prefer three lines of code in /system/etc/hw_config.sh
mkswap /dev/block/mmcblk0p2
echo 30 > /proc/sys/vm/swappiness
swapon /dev/block/mmcblk0p2
Try this to see if works

but if rom/kernel doesn't support then gonna use swapper2 from the market.
or else follow hunff instruction and open terminal emulator
-type free
-swap 0 0 0 = not active use swapper2
-swap any value other than 0 = active
Thank you it works!

I am using reset swap app as my title says!
but i tried swapper2 and it says such a directory doesnt exist or other error message forgot it.
I thought ,that swap doesn't work if the kernel doesn't supporting it.
So you say that you can have swap if you have stock kernel(by using swapper?.

not sure about what he said...
i know you cant use swap partition to set swap with stock kernel
but dont know about swapper through FAT32
