Compcache w/ back_swap VS. Linux-swap?

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;

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.

Hi Phillip, this looks like it has some promise. Can you give some more specifics (commands) for the noobs (like once you open ADB, what then?), or, does a menu come up? I am at adb remount/successful. now what? Thanks.

All you have to do is run config.bat, don't run adb. Type the number of what you want it to do.
Here's some more explanation of what this does, minus the obvious ones.
[1] Edit user.conf
This will automatically pull the user.conf file and open an editor, then automatically put it back on your phone after you make your changes and save.
[2] Swap status
[3] Turn Swap On
[4] Turn Swap Off
[5] Set swappiness
This asks for a value then sets the swappiness to that value.
[6] Memory Status
This shows how much RAM and swap is available and how much is in use.
[7] Partition SD Card
This asks what filesystem you want (EXT2, EXT3, EXT4) on your SDcard, and how big you want the swap partition to be, then formats the card have a FAT32, EXT?, and Swap partition.
[8] Mount SDCARD in recovery
This gives your SDCARD a drive letter in windows while the phone is in recovery mode.
[9] Unmount SDCARD in recovery
[10] Erase EXT partition
[11] Backup EXT partition
This copies the files in your EXT partition to a folder on your computer.
[12] Restore EXT partition
[13] Push lockscreen image
This takes a picture you put in the same folder as config.bat and makes it the background image of your lockscreen.
[14] Reboot device to recovery
[15] Reboot device

Yeah, this is gonna be sweet when I get some time to play around with it. If I have ?'s would you prefer PM's or in open forum?

This looks awesome. Do you have to already have apps2sd on your mt3g for use of step 7? Or is this just an easier way to do so?

7 is to create partitions on the card, then if you flash a rom that uses apps2sd it'll use that ext partition. It uses sdparted to create the partitions, which I think has become standard on most roms. If you flash a rom without it, you can put it on there using the link the first post.

CPU status readings
Hi Phillip, I'm having a lot of fun with your configurator. I would like to ask your opinions on some things related to CPU speed. To that end, I have enclosed the user.conf text I ran, below. The first question is, though: do you have an opinion as to whether the Overclock Widget app causes any potential conflicts or issues? If so, I will get rid of it. My sense from communicating with Mike Taylor on the JACxROM thread is that the ROM more or less sets the CPU automatically. Next, as I understand it, if sacrificing a bit of battery life is acceptable, then the minimum frequency can be set higher, and in one of his last posts he recommended 245760. From what I am attaching below, I am not savvy enough to know exactly what I've got going here. The terms "scaling min freq" and "default" are a little bit beyond me. Bottom line: is the lowest setting currently 128000 or 245760, and is there really any harm in having it set to this level or even higher? I'm almost always plugged into some power source, so battery life does not concern me. Finally, please explain what this means at the bottom of the reading: "percent cpu usage before going up a speed step". Thanks...

I'm glad you're getting use out of it. I've never used the overclock widget, as you said, you don't really need it because the rom does it for you. I set the minimum cpu to 384000 and up threshold to 30 and it stays speedy.
The up threshold - the percent cpu usage before going up a step means how much of the cpu do you want to get used before it speeds the cpu up. I set this at 30. I really don't know if these settings do any damage, but it runs fast. I'm sure the battery takes a hit, but my phone stays plugged in a lot.
For the user.conf file I make these changes:
compcache_en=0
cc_backingswap_en=0
linux_swap_en=1
swappiness=40
scaling_min_freq= 384000

Sorry, I think I'm doing something wrong. I just changed those values, hit "enter", x'ed out of the cmd screen, reopened, entered "1", but the values did not change. Is there a final step I am missing? Do I need to click "save" in the drop down of the cmd screen instead of "enter" on the keyboard?

I see what happened. You edited the temp file that gets put on your computer and saved it, but closed the command window before it was put back on your phone. After saving your edits, you have to choose 'exit' from the file menu. That'll exit the editor, then put the changed file onto your phone and return you to the menu.

OK, that was beyond easy. Thanx again. One last question (for now): I know even less about the whole compcache/linux swap thing than I do about CPU settings. However, I think I get it that you either use one or the other, and in post #9 I'm assuming you're using the linux swap and not compcache. Can you explain why you chose one over the other? I know there's all sorts of debates, just wanted to hear your thoughts on the subject.

I use linux swap because I'm running jacxheroski 2.1 (I tried 2.2a/b/r4 and it was too buggy and rebooted) and compcache doesn't work on the MyTouch on 2.1. I really don't know anything about how each works and how they are different, I just know linux swap works for me.

Good enough. Yup, I'm gathering as I read more, "to each his own". Mike recommended the settings he put into the JACxROM, so I'll go with the master's recommendations. Thanks again.

new info
Hi Phillip, long story shorter, Mike changed some things up on the earlier JACxROM version, and based on what he said and what I'm attaching, it appears linux swap vs. compcache is the way to go on that one. He recommends a 64 MB swap partition. I am not able to tell what size it is. Can you? Your configurator is really fun but still a bit beyond me...

Using swap automatically uses the full swap partition (whatever size you set when you formatted the SD card).
Use "[6] Memory Status" from the menu.
Your total swap size will be across from "Swap:" under "total" heres mine (62676):
Code:
total used free shared buffers
Mem: 97852 96120 1732 0 620
Swap: 62676 25528 37148
Total: 160528 121648 38880

any chance of this being converted to linux-friendly ?!
I might be able to do the work to convert the script to linux-friendly, if mr hooper would allow it!

That'd be awesome. I don't use linux, but if you want to knock that out, feel free. I'll add it to the first post.

Hi, I'm new to Android.
I installed the SDK, and put your script in ../android/tools
Yes, I put ../android/tools in my path (winxp).
I'm running Cyanogenmod 4.1.999
when I run your script, it says 'Device state is unknown'.
I can mount my sdcard as a removable drive when I connect it via usb to my computer. Did I not install something that I needed to?
Also, does anyone know where Cyanogen put the user.conf in his mod?
Thanks in advance and sorry for my noobitude.

If you are in recovery mode it should say device is unknown. This is normal. If the phone is booted and shows unknown then you'll want to be sure you installed the usb_drivers from the sdk properly.

Thanks, that worked.
I have 2 computers, drivers would not update on one, but the were able to install on the other. Can't figure out why.
I'm using cyanogenmod 4.1.999, and it says that I don't have a user.conf, and it also says 'system/bin/swap not found'.
This is what it shows when I press 6 (memory status):
total used free shared buffers
Mem: 98140 96300 1840 0 432
Swap: 96812 24520 72292
Total: 194952 120820 74132
Device is booted.
Is it normal for that much memory to be used (I have the 192mb Mytouch)?
P.S., thanks for the Configurator app!

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

Defy Mini: Updated the overclock-module

-- Update:
User Guitwo2 wrote an excellent init.d-script to load the overclock-module on boot. To make it even easier to use, he made a flashable zip. See this post: http://forum.xda-developers.com/showpost.php?p=39659179&postcount=6
Hi,
i recently updated the overclock-module (see attachement). Before starting it, find the required addresses in memory, as the module's defaults match only the RTFR-Firmware:
Find address of transition-table
Open adb-shell, become su and type
Code:
cat /proc/kallsyms | grep -A 1 pll0_960_pll1_245_pll2_1200_pll4_800_25a
You'll find the address at the leftmost side in the first row of the result.
Find address time-in-state-table
In the same shell, type
Code:
cat /proc/kallsyms | grep -A 1 cpufreq_stats_table
Again, the required address ist at the left side of the first row.
Then, one can try to install the kernel module. Parameter "pll2_l_val" ist used to adjust the multiplier of pll2. Default is 62, i got it stable at 69 (=CPU-Speed of 69 * 19.2 Mhz / 2 = 662 MHz). You can also try to set the multipliers of pll0 and pll1. I didn't test it.
So, with the above addresses one types the following to load the kernel module (replace the addresses with the ones you found, where parameter acpu_freq_tbl_addr equals transition-table and parameter cpufreq_stats_tbl_addr takes the time-in-state-table-address) :
Code:
busybox insmod /sdcard/temp/defymini_oc.ko pll2_l_val=63 acpu_freq_tbl_addr=0xc0755bdc cpufreq_stats_tbl_addr=0xc0789134
Update: In version 0.3 there is another parameter, "vdd", which takes a value between 1 and 7 (don't play with it, as there is no error handling!), where 1 is the lowest and 7 the highest vdd. Default is 6.
CHANGELOG
2013-04-29 0.4 added source (use it for other devices with locked bootloader)
2013-04-08 0.4 beautified messages, show current vdd
2013-04-01 0.3 added vdd-level for highest freq as parameter
2013-03-27 0.2 added time-in-state table modification (CPUSpy etc)
2013-03-21 0.1 initial release

No, but we can change the definition for soc-id 96 to msm7225aa. I did it. Didn't work. when switching to 800Mhz via PLL4, device hangs and reboots.

Probably not supported in kernel or we can try some how to patch it via modules like the Motorola Defy MB525/MB526 which has a locked bootloader or try to obtain the Defy XT535 kernel aka boot.img and flash it via fastboot but it's risky. I can't get the memory addresses. Just upload your boot.img from your nandroid backup so I can flash it via fastboot. What's the difference between PLL2 overclocking and PLL4 overclock?

I just followed your instructions.
The addresses were the same.
It seems to work so far.
Mine seems stable too.
Great work !
I am loading it on boot via a init.d script.
With : TNBST_4_0A.1F.0ERPS - WE_Orange_Spain_v22_0223_FLEXTNBST
What could we probably gain by increasing PLL0 and PLL1 ?
And which value should we choose ?
With pll2: 70 I get 672MHz stable.

If you want to load the module on boot and have init.d support, there is attached a init.d script that will do it automatically.
There is a CWM flashable zip
0 - push the XT320_overclock.zip on your sdcard
1 - Make sure you have busybox installed
2 - Reboot with a CWM... (recovery.img attached)
Code:
>adb reboot bootloader
> fastboot boot recovery.img
3 - Flash XT320_overclock.zip thorough CWM
4 - Enjoy !
Default values are : pll2=69 and vdd=6
Edit /etc/init.d/66ocmodule for further tweaking.
In V2 - updater-script has been updated, to fix busybox permission issues.
66ocmodule script change log :
V0.1
First be sure to adjust pll2_l_val, acpu_freq_tbl_addr and cpufreq_stats_tbl_addr.
Be sure that defymini_oc.ko is in /sdcard/
1 - push the module to your phone :
Code:
adb push 66ocmodule.txt /sdcard/66ocmodule.txt
2 - in shell mode, remove the extension .txt and move the file to /etc/init.d folder
Code:
mv /sdcard/66ocmodule.txt /etc/init.d/66ocmodule
3 - Change mode to -rwxrwxrwx
Code:
chmod 777 /etc/init.d/66ocmodule
4 - Change user/group to root/root
Code:
chown 0.0 /etc/init.d/66ocmodule
That should work.
NB : you may have to remount your /system partition in rw to change user/group
Code:
busybox mount -o remount,rw -t auto /system
NB2: For init.d support go to : http://forum.xda-developers.com/showthread.php?t=1933849
NB3: have only one version of 66ocmodule in your /etc/init.d directory to avoid trouble.
NB4: if you are experiencing trouble with step 2, use
Code:
cp /sdcard/66ocmodule_vX.X.txt /etc/init.d/66ocmodule
rm /sdcard/66ocmodule_vX.X.txt
where X.X is the number version
NB5: be extra careful when editing the files. You could mess when with the end of line markers. I recommend using Notepad++ and check if the end of line markers are in unix format (LF) (view/show symbol/show all characters). You can correct that easily with edit/EOL conversion/convert to UNIX format
NB6: make sure there is a blank line in the end of the file as well
V0.2
gets automatically the needed addresses.
Module is supposed to be located at /data/defymini_oc.ko
If troubleshoot refer to the /data/oc.log log file.
Set for a 700MHz oc
Follow steps 1 to 4 for installation. Read NB, NB2 and NB3.
V0.3
Checks for the presence of older versions and gives a warning
Checks if the module is already loaded (unload if true)
Chekcs in the end if the module is loaded
+ Minor changes
pll value and module path can be edited in the beginning of the file

V0.9
Can adjust all pll values.

What could we probably gain by increasing PLL0 and PLL1 ?
And which value should we choose ?
Click to expand...
Click to collapse
Tried to oc pll1 -> distorted display. can't recommend that. OC'ing PLL0 leads to somewhat faster 480 MHz frequency (480 MHz is generated by PLL0 and DIV2, so 960MHz / 2 => 480 MHz.) In the module only changed PLL2 is payed attention for modified frequency-tables.

Simple difference: PLL2 exists in SOC, PLL4 does not exist. So Motorola didn't underclock something, they got a crippled MSM7225A. Speed ist limitied by hardware.

I'm pushing pll2_l_val to 73 (+11)
I get 700 MHz stable for now. Without overeating.
I'll keep you posted.

Do you still use the "performance" governor?

Re: Defy-Mini: Updated the overclock-module
I use setCPU with different governor. All seems to work. Higher freq (600) is replaced by a new one thanks to your OC module.
Btw 700 is stable. I runned some stress tests. Performances are increased. Linpack score goes from. 14.5 to 17.5 MFLOPS.
I was wondering if the soc pll were used by other stuff than cpu. Could explain your troubleshoot when oc pll0.

It's definatly a good sign if your phone doesn't reboot. Just check the Frequencies using CPU-Spy or something else.
And please post your Firmware-Version and the adresses you used, i'll add them in the first post.

I just installed your module from the first post and i changed value from 63 to 70, and now i have 672mhz. How can i change pll2 value again? What do i type? If i use your module but with 73 instead od 63 i get: File already exists.

You have to remove the module first (no need to reboot):
Code:
rmmod defymini_oc.ko
Then you can install the module again.

Alright i've used 66overclock file and pushed it manually with root explorer, changed permissions, set owner and i've edited it so pll2 is 73. My phone is rebooting atm, i will post if i had success.

EXPAND VIRTUAL RAM using LINUX PARTITION

linux partition using cwm recovery
&
increasing virtual ram​
Perform Following:
1. Remove all Swapper/Swapper2/RamExpander/Ram-Manager or Swap creating any apps that you are using currently
2. Remove swap.swap or any such swap files from sdcard root (if any you find)
3. Now take full Backup of your SDCARD contents-bcoz You are going to format it
4.Install CWMRecovery (if not already having it on your Device)
5. Reboot into CWM Recovery and go to 'advanced'--> "partition your sdcard"
Click to expand...
Click to collapse
Creating CWM partition(Linux Partition):
Choose following parameters while creatig partition:
Partition Size: 1014MB
Swap Size:256MB
Confirm & Execute process. You can parameters according to your understanding as well.
It will wipe all data/partitions on sdcard and will create a new linux (ext3) partition on sdcard with a swap worth 256MB. Reboot Device when process completes.

Adding init.d script Support to your ROM (If on stock ROM)
Requirement: You must have busybox installed prior to proceeding for next step
This step is for those who are not on Custom ROMs. All Custom ROM preferably have busybox & init.d support functionality inbuilt and carry init.d folder in /system/etc/<here>
1. Download Installing and activating Uni-init.v1.0.apk will create and activate init.d folder in your /system/etc/<init.d>.
3. init.d folder will carry system tweaks to enhance performance
Click to expand...
Click to collapse
Adding init.d Tweaks Collection:General tweaks and Tweaks related to Linux partition:
1.Now download all init.d Tweaks and copy them into your init.d folder
2.Check whether it has "androidswap' files or not if not download it from 'files' section or somewhere from pinned posts. 'androidswap' carries codes and will create swap on your linux partition.
3.Open androidswap using notepad++ and set swappiness to be created 60(recommended). (You can experiment here settings swappines from 50-100)
Script will looks as below:
#!/system/bin/sh
swapon dev/block/mmcblk0p3
echo 60 > /proc/sys/vm/swappiness
Click to expand...
Click to collapse
4. If you have not edited androidswap then skip above step. If you have increased swappiness count then Move the edited file to your /system/etc/init.d/<here>
5. 'androidswap' and 'fstab' that you find in init.d now will be setting up your CWM partition to work properly.
6. U can check the active swap on sdcard after a reboot using adb shell commands or using Terminal emulator.
