[FIX][SCRIPT] Fixed zram for franco 2.6.32.x kernels (v18,v19) plus remount speedups

If you do not know what is this about and do not have any problems, leave the scripts alone and go on with your life.

Attached.
1a. Fixed zram.zip for franco kernels v18/v19
Fixed by removing the 00remount script from /system/etc/init.d, since it messes up with boot on phones with DT's apps2sd (and probably other similar scripts) - a2sd fails to mount sd-ext partition, phone "hangs" on LG logo.
If you are already stuck after flashing franco's original zram.zip due to this issue, then go to recovery, mount /system there, and
Code:
> adb shell
# rm -f /system/etc/init.d/00remount
# exit
> adb reboot
Alternatively, flash remove-zram.zip and reboot. This will remove ZRAM altogether.
There is no ZRAM support on franco's 2.6.35.x (v1) kernels, flashing this there is absolutely useless

1b. remove-zram.zip: Removes ZRAM. Deletes the following files if they exist:
Code:
/system/bin/zramconfig
/system/etc/zram.sh
/system/etc/init.d/00remount
/system/etc/init.d/00zram
2. remount-noatime.zip
Remounts all your filesystems with noatime,nodiratime options (potential I/O speedup). Taken from the original zram.zip and renamed to 98remount so that it comes after all other stuff is done.
3. remount-noatime-nobarrier.zip
Same as above, plus remounts ext4 with barrier=0 option for users with sd-ext on ext4. (potential I/O speedup)
Q: What is zram?! I do not understand what is this about!
A: Read the red warning.
Q: How can I find whether my kernel supports ZRAM?
A: Use the shell.
Code:
# zcat /proc/config.gz | grep ZRAM | grep -v ^#
CONFIG_ZRAM=y
Q: What is noatime, nodiratime, barriers?
A: Google it!
Q: I deleted the 00remount script as advised in recovery, but still have issues with A2SD not mounting my sd-ext!
A: If you are using CM7 ROM, then delete /system/etc/init.d/05mountsd as well. (Rename to _05mountsd or whatever else that does not start with digits should do as well.)

As the doctor already mentioned... THis script is for those who get issues with boot up of their OS..!! Read the FIRST POST...!!
If your phone is working fine then this is not for you...!!!

Good one.
Prepare for 40 thousand posts asking if this script makes coffee and cleans the house for you.

Fresh installed 6.5.7 then fk19 then revised zram then noatime then dt a2sd (rebooting in between ofc) and got stuck again after flashing a2sd.
Got in recovery and deleted the 2 scripts from init.d via adb then reboot. It rebooted ok and I thought yeeah we're done. I did another reboot afterwards and it stuck again.
Trying to figure out what to try next. That's a way to spend my vacations lol

See adb logcat

I'll be the first. Does it make coffee and clean the house for me?
Btw glad your hissy fit is over. Good to have you back.

Is there anyway to remove ZRAM after installing the original ZRAM?
I have been following franco kernel since v16.
Now i'm using V19.1.. and i have installed ZRAM for the first time after flashing 19.1
My phone has random reboots and i guess the sole cause is ZRAM.
Is there anyway to disable ZRAM? THANKS!
NOTE: I have tried to revert back to v19 but same issue.. random reboots.

Delete /system/etc/init.d/00zram
Finally, I very much doubt that zram is causing reboots for you. It is merely a swap.

dr. I´m using Juwe11 RamScript, as far as I can see theres no duplicate stuff between your last script and his so i can use both, but my question is if its better that your script runs after him, now yours run first because of the files name.

[KernelModule] Overclock

**** Do Not Repost! Link back to this thread! ****
*** Update: This works on Thrill/Optimus 3D. There are seperate kernel modules for Froyo/GingerBread/CyanogenMod kernels***
Here ya go... I prefer this method rather than hard coding changes in the kernel. Assuming you have both kernel modules extracted to /sdcard
Switch to root
Code:
$ su
Copy files from sdcard to /system/lib/modules directory - You only do this once
Code:
# cp /sdcard/symsearch.ko /system/lib/modules/symsearch.ko
# cp /sdcard/opperator.ko /system/lib/modules/opperator.ko
Load modules, always do symsearch.ko first - You do this every time you reboot
Code:
# insmod /system/lib/modules/symsearch.ko
# insmod /system/lib/modules/opperator.ko
Set Frequency - You do this when you want to change frequency - in hz, that's 6 additions Zero's to make Mhz
Code:
# echo 1188000000 > /proc/opperator
This uses SYMSEARCH by Skrilax_CZ
https://github.com/SkrilaxCZ
Inspired by Milestone Overclock by Tiago Sousa, but totally rewritten for omap kernel 2.6.35-7 and above.
http://code.google.com/p/milestone-overclock/
This is a stripped down version. I'm working on a fully featured version, that will allow you to play with voltage as well. There are some hurdles to overcome before that is ready for prime time... In the mean time, lets see what stock voltage can do... 1188 is my sweet spot on stock voltage, what is yours? I get up to 1235 without reboots, or real noticeable lags but the linkpacks are all over the place, where it stays in the 80's at 1188. And remember, the number is in hz a.k.a. cycles per second, so to get Mhz, you must add 'Six Zeroes' to the end of your desired Mhz.
* Note2Devs: Feel free to put this in your ROM, but please do credit me for the Overclock in your release, and link back to this thread. You can also post a link to your ROM here as a way to make myself and other aware of it. Thanks...
* Echts shows us how he integrate's the module into his own ROM. TY, Echts...
http://forum.xda-developers.com/showpost.php?p=19542521&postcount=52
* Thanks to greenbats for helping figure out the O3D gingerbread kernel issue!
** And don't ask to put it in an app. I won't be happy about that. I'm serious! **

Yes, give this a go on the O3D, the module is actually compiled against the cyanogenmod cosmo kernel, which is really for the O3D. Should work.

No real installing... It's just the modules... You can throw them in /system/lib/modules, and then use an init script to load them up, then set the frequency, but don't do that until you know what works *STABLE* for you.
If you have a favorite ROM, let the dev know about this, and maybe they'll integrate it.
I'm not sure if custom kernels like acurateam's might be too different to work properly at this point. But it won't hurt to try. Just don't start loading it at boot right away.

What I'd really like is for the ROM making dev's to come to a consensus as to how to integrate this... Mainly, the best place to throw the script that does this at boot on these phones. I know how we did it on droid X, but I haven't dug deep enough into this phone just yet to be sure... I'll update the OP as methods improve and I get more feedback.

Or use callmearia kernel and make script for system/etc/init folder... havent tried his kernel but it should support the script at boot up. Acura roms should work that way too.
The way most roms use overclock is the init script that starts at boot...

Those would have been based on Milestone Overclock... Which is where I gained most of my knowledge by contributing to getting the droidx/2 side of things working. MO's method of manipulating frequency and voltage no longer works on OMAP4, or rather kernel 2.6.35+... I had to come up with a new way of doing things, which didn't fit well under the existing framework of MO. So, I started from scratch... This is just the tip of the iceberg... Basic, basic, basic...

i get insmod: init_module /system/lib/modules/symsearch.ko failed (exec format error).
What am i doing wrong?

I also get the same error: insmod: init_module '/system/lib/modules/symsearch.ko' failed (exec format error)
Is it because I have gingerbread?
Must I use froyo?

Thanks for all your hard work! I look forward to seeing what else you come up with!

One thing I desperately need is mass storage support. However, I am not asking that of you (IDK for sure if that would involve the kernel or the ROM or both, anyway). I would like some help with my ad hoc solution. I have this program NetDrive that can mount an FTP connection as a local drive, which is great in conjunction with FTPDroid as a replacement for mass storage. My only problem is that I cannot use FTPDroid where there is no Wi-Fi, so at home I have to use cyansmoker's Alt Mounter, which only sets up FTP for /sdcard. So, is there any chance you could set the kernel to mount the external SD card within the /sdcard folder (I know there are some ROMs for other devices that mount it under /sdcard/sd)?

undervolt and overclock performance and save battery

You can save battery and have great performance by undervolting/overclocking cpu and underclocking gpu, the best way i found is a script in rom toolbox.
i run on maverick 4.5 and try this day on 4.0
and this link :
http://rootzwiki.com/topic/14511-opptimizer-projekt-milestone-overclock-for-omap4-devices/
for me my values are:
for cpu
mpu_opps[3] rate=1200000000 opp_id=3 vsel=61 u_volt=1345000
mpu_opps[2] rate=800000000 opp_id=2 vsel=55 u_volt=1200000
mpu_opps[1] rate=600000000 opp_id=1 vsel=43 u_volt=1100000
mpu_opps[0] rate=300000000 opp_id=0 vsel=26 u_volt=1005000
for gpu
gpu_opps[1] rate=307200000 opp_id=1 u_volt=1125000
I started all the values with romtoolbox and create a script at boot
open rom toolbox / open tools / open scripter / then create new script
script name:
overclock
commands:
#su
echo 3 1200000000 1345000 > /proc/overclock/mpu_opps
save, and click on your new script and select "at boot"
re create a new script for the other values, for me a total of 5 script, 4 for the cpu and one for the gpu
The governor is mot_hotplug or boostedassV2.
I tried a lot of voltage values, the more stable are here for me.
I think this run on many rom, not only on maverick
The dev can implement this in rom ?

Try in terminal emulator (on rom toolbox or other)
To verify your value or your script after boot
#su
cat /proc/overclock/mpu_opps
To validate one value (for example)
#su
echo 3 1100000000 1360000 > /proc/overclock/mpu_opps
Then press enter
Then re verify (cat /proc/overclock/mpu_opps)

[Q] Change Governor Before Flashing

Is there a possible method to change default governor like "ondemand" to "conservative" before flashing the ROM ??? What I mean is can any user change any ROM value in any file to achieve the same so that ROMS which does not have CPU Control ( Like AOSP ) can boot up with conservative governor ???

AFAIR,in kernel config u need to change this while compiling:

Or use an init.d script,copy paste this and set permissions
