Thanks to Neldar for BLN
Thanks to Supercurio for voodoo additions
Thanks to zurchpet and js8 for dedicated testing
Thanks to Andro1d for ideas

Thanks to virnik for the new boot logo
For safety purposes /dev/block/stl3 is not mounted anymore but /efs is copied to /dbdata.
Quick table on the versions:
Two branches: Stable (which is stable) and Bleeding Edge (includes latest changes, in testing, consult the changelog)
Two versions in each branch: Normal (without preemptive RCU) and Ultra (with preemptive RCU)

You must flash a normal kernel before Ultra or you will not have phone/modem
Ultra does NOT support RFS filesystem
This kernel can now also be flashed from DOC rom in http://romkitchen.org thanks to Stefunel, choose a non wipe rom.
You can get it at . Normal version is named zImage-rXXX and Ultra is named zImage-ultra-rXXX.
Logs are in /fugumod.log
You can get support on #romkitchen on irc.freenode.net
Unless some unexpected changes occur, I am not going to produce any overclocked kernel anytime in the future as they have proven multiple times to be too unstable.
- All versions are upgradeable to the latest one without any data loss.
- You must have at least 400Mb free on your internal SD card storage for conversions. If you don't have any apps installed. If you have apps already installed, you must ensure that you have at least the same size as you data storage free on the sdcard. Note that upgrades don't really need space on your external storage.
- It is only known to work with international GT-I9000 and the Bell 9000M.
- The cleanest way to revert the mod is to reflash a complete ROM. But now supports reverting to RFS as well.
- If you use another custom kernel, you don't need anymore to revert the lagfix before applying. But it is always a good idea to start from a clean ROM.
Locale/timezone reset when using some filesystems
Some people may see that time zone sometimes reset at boot or even language reset, the easy solution is to edit /system/default.prop with something like:
persist.sys.timezone=Europe/Brussels
persist.sys.language=en
persist.sys.country=BE
Click to expand...
Click to collapse
Chances are that those settings are not in your /system/default.prop, it is safe to append them after the already defined ones.
See [url]http://en.wikipedia.org/wiki/List_of_zoneinfo_timezones for your timezone
How to convert filesystems:
Use FuguApp or FuguAppFree or create a /sdcard/fugumod/fs.convert file. If you don't see the paid version in the market and only see the free one, it may be due to your ROM build prop, just change it with SGS tools (in SGS tools -> prop editor -> build.prop -> Unlock -> ro.build.fingerprint=samsung/GT-I9000/GT-I9000:2.3.3/GINGERBREAD/XWJVB:user/release-keys and leave the rest as is. save, Apply script -> clear market cache, reboot...)
You can also create a /sdcard/fugumod/fs.convert which has the same syntax as /sdcard/fugumod/fs.current
How to specify custom filesystem mount options:
Create a file called /sdcard/fugumod/fs.options
It should contain the FS options like shown below (not specify a fs is equivalent to no option). Options "noexec nodiratime nosuid nodev nosuid" are "enforced".
stl9 noatime,barrier=0
stl10 noatime,barrier=1
stl11 noatime,notail
mmcblk0p2 relatime,barrier=0

Root bug with some applications:
Some applications don't properly detect if the phone is rooted, generally because they expect su to be in /system/xbin
Solution: type the following commands as root using adb shell or connectbot or any other shell console:
mount -o remount,rw /system
mkdir -p /system/xbin
cp /sbin/su /system/xbin/
mount -o remount,ro /system

What is Ultra version
Ultra version is a version with a preemptive RCU which brings an impressive user experience by having a near realtime response. Interestingly, it also seem to boost quadrant scores by ~15%.
Bleeding Edge can be found here
But it is not compatible with RFS filesystem, so don't flash if
- you still use RFS in any of /system, /data, /dbdata , /cache
- you haven't at last booted once a normal FuguMod edition
- you don't have basic skills of recovering from soft bricking (generally, flashing a normal edition will solve soft brick with Ultra)
Start adbd as root
If you want to start adbd as root and in recovery, you need to create a file called /sdcard/fugumod/debug
The change will only take place on next reboot.
Why is quadrant score so low ~1000 in ext4 but I still feel my phone is really fast?
- Quadrant does no measure latency, but user does it. You could have a completely unresponsive phone with very high quadrant score.
- I use safe mounts for ext4, but if you feel brave enough, you can tweak them using fs.options explained earlier or switch to JFS.
- Some ROMs/kernels set "media.stagefright.enable-player=true" in build.prop, in general this will give you 500+ supplementary quadrant score but but will break playing some videos. This won't make your phone faster or more responsive or whatever, it will only boost your quadrant score and break some videos.
Which filesystem is the best?
This all depends on your perception. I general, having /system on reiserfs and all others on jfs seems to be the fastest.
Random reboots
They are known to happen if:
- you force switch the radio band for example using "band selection" in diagnostic menu from wcdma 1900/2100 to 850 or 900 gsm.
Wifi not working
If your wifi is not working anymore, you probably use a JVH based ROM and have restored your wifi settings via titanium backup (or possibly other backup utilities). Wifi configuration from pre-JVH is not compatible with JVH ROMs. You should be able to restore without reflashing a full ROM by stopping wifi, then doing the following commands in a root shell.
cd /data/wifi
cp bcm_supp.conf bcm_supp.conf.bak
cp wpa_supplicant.conf wpa_supplicant.conf.bak
rm bcm_supp.conf
ln -s wpa_supplicant.conf bcm_supp.conf
cat bcm_supp.conf.bak | head -n5 > wpa_supplicant.conf
cat wpa_supplicant.conf.bak >> wpa_supplicant.conf
rm wpa_supplicant.conf.bak bcm_supp.conf.bak

Have you tried with ReiserFS and XFS ?? Because I wanted to test with those even if they might use more cpu they should be faster, but I didn't had the time to,
Yeah this is interesting.
I must admit I hesitated between Ext4 and JFS during original choice for Voodoo and after a lot of reading (and head scratching) I chose Ext4 mostrly because of the ease to get e2fsprogs working, and their maturity.
Hey guys I love the developers society I'm glad to see that our phone has such hard working developers! Looking forward to good news from you

Hello,
I was not intending to post this at first, but it seems some people are interested in my works on the Galaxy S.
I made a very raw script to convert /data to jfs on the external SD (at the moment).
I am open to all suggestions, so feel free to post

By the way, if you want to avoid creating new script (conversion, etc) I suppose you can "port" Voodoo to JFS in a few minutes.
Don't hesitate to ask for details if you're interested in.
I'm curious about this, I feel like I could have underestimate JFS for mobile (about the low CPU utilization part), like, you know, the general underestimation of this filesystem.
On my tests, the battery really used by the filesystem itself is really minimal, but still

I did not try xfs, but reiserfs did quadrant scores of about 1200.
XFS overhead is higher than many others, so battery wise, it may not be a good idea. If you wish to test, I made an xfs.ko module on my site (even a btrfs one).
This page is an interesting read, what's your opinion about this?

I experienced a bad habit that XFS has, it tend to produce garbage in files when not powered down cleanly
XFS was mostly designed to work efficiently with big files.
JFS looks like a more sensible choice

I know about this, but under android, memory pressure should be sufficient to force writes.
Also it's not very clear how this affects the filesystem. If someones first job is to power the system unproperly, then with whatever filesystem, you will have problems at some point. Also, there is a "discussion" about this here too:

I would love to use the mods and tweaks I hear about (Adrenaline Mod, Supercharged V6) on my Incredible, but I'm a little lost with the installations. What exactly happens when these are flashed? What do the scripts do? What if I have other things in my init.d folder? I have MIUI and Incredikernel, will these mods even work?

The V6 and adrenaline mods are scripts not flashable mods. You run them thru a script manager or terminal emulator. These mods change many settings on your phone to improove performance, such as memory limits. It does not mater if you already have init.d scripts, there is no limit to the number you can have. These mods work on almost all custom roms and kernels including MIUI and incredikernel.

hi....i tested the best way is flash bionic cow 2 rom and follow my guide here using adrenaline engine v3
here is the link : http://forum.xda-developers.com/showthread.php?t=1570764

I think it is the best memory management.

I am not sure, but I use Zepps V6 SC [latest beta''s linked] for it's use of KAK also, and Nitro, and Widgets for Fast Engine Flush [Recover RAM] and Super Clean Reboot, wiping the Dalvik on reboot!!!

When you run v6 supercharger you can use option 21 for nitro lag. It is ment to help with smoothness and make it more snappier.
You can also add daily schedule's with script manager to run a fast engine flush(Recovers ram and reduces lag) and then you can have widgets on your homescreen to make sure its working or to use different settings as in more multitasking or aggressive settings...
I use ram manager myself as i find it better for gaming. Simple as irish said. V6 is free but Ram manager is easier to use and less complicated but you cant run engine flushes or wipe dalvik cache. But ya can wipe dalvik cache with Titanium backup or Clockworkmod and then and quick reboot helps as well...

I would recommend you go to the link I provided, and learn about V6 directly, by reading Zeppo's own words, and the comments of various users, there is much to learn, and it is useful.
I have compiled this little Slide Show, to show how widgets, Fast Flush to regain Memory, and Superclean Reboot, clearing the Dalvik Cache....
I used Script Manager [ads] in conjunction with V6 SC......
and the scripts are Zeppo's.....
you must make them Favourites, and Root, in Script manager!!!!
BTW, Hi Snwman....
AKAIK, TB only allows you to Clean Up Dalvik......
it doesn't wipe it if it deems it not necessary, in other words, if you have Apps which match what Dalvik has....
SuperClean wipes anyway...poof!!!!

Your right had a look there thought it said wipe. But you can always use CWM to wipe dalvik cache.
Either way it's best to try each out them out and see what works for you
I use v6 supercharger for a while, and very satisfied with the performance boost so far..
Try it for yourself
i am using v6 superchager, and it is awesome
I'm using the V6 script as well and just to add to everything that's been said,I noticed if you're running stock TouchwiZ and you have empty homscreens,don't delete them.Its better to keep all 7 homscreens.Deleting them seems to permanently take away the smoothness you get after using the V6 Script.Can't explain why but just my observation.

Hey guys, not sure if I should be posting this in this section, but I'm not certain that is dev issue too and even if it I can't post in dev section yet. What I want to say is: if it is in the wrong section, please, move it ^^
I'm posting this for those who is seeking improvement in performance and battery saving just using tweaks in governors.
Q:What did I do?
A: I just made a init.d script with some tweaks that I wanted.
Q:What was your objective?
A: I wanted to save some battery and not lose performance. I wanted much?
Q:Where did get that from?
A: All credits to droidphile. His guide that helped me. If you want to make your own script for your favorite governor and i/o scheduler, look at his guide in http://forum.xda-developers.com/showthread.php?t=1369817
Explanations:
What I did was take droidphile tips and mod it a little bit. In his guide and explanations, he gave two types : battery friendly and for perfomance. A just merged one and other and made one that don't lost much perfomance neither sacrificies much battery. I'm ver happy with the result.
The script is in appendix. To use the file, rename without .pdf format
Explanations:
The governor in use is ondemand. I'm using arco68 CM9 for our SWG and waiting for CM10. Unhappily, I don't have enough experience to help debug CM10 and help the beta release come faster. The best I can do in the momment is wait. And I'm using supercharger V6 RC10, by zeppenlinrox.
Some tips if you want to make your on script:
- If you're using Windows, use Notepad++ to write it. You've to set up it in ANSI code (in format). Also go to edit>end line conversion>UNIX.
- Before you save, check every line and don't leave any left space, just to be sure that the script will be read right.
- Save with no format. No ".txt", no ".sh", no nothing.
- Follow to the letter droidphile steps.
That's it
*******************05/fev/2013*********************************************
Hey guys, I discovered that my attachment didn't work properly. So I made the right changes and now every line on the script run alright. Recently, I flashed another kernel (I'm using arco68 CM9 for i8150) because I wanted some new features such better governors and SIO scheduler. This kernel can be found in http://forum.xda-developers.com/showthread.php?t=1855557, credits to forfivo for it
And after flashed forfivo kernel, I made some changes and scaled my governor as ondemandx, so I'll attach this file here too. If someone want to flash his kernel too, try v2 because I think that v3 is still instable.

Edit: not working for me. It doesn't pass boot animation. Vanir ROM with /data and /cache in F2FS.

f2fs is just experimental. tried it and actually .. it is not as stable as ext4. the whole story about f2f's performance over ext4's performance is just placebo effect. tried it on galaxy nexus and also on s4.. both models without any real benefit from f2fs system. EXT4 is just better and most stable. that's it.
Don't really know much about f2fs because i never used it...
But if you want it, i can add it into the kernel then you can take your decision what you want use

f2fs support was in r398, franco just missed one or two commits for the ramdisk i think so f2fs didn't work....but @osm0sis'es last synapsed version works very well with f2fs on data and cache and system on ext4.
i think he gave permission to use his latest ramdisk

fancy and smitty. yes, it shows upgrade in w/r performance at tests but there is no feeling of anything better compared to ext4. Do you know why PA-Team has never supported f2fs? Totally because it's experiment. The same like ART in KitKat. You can send logs to check some bugs only if its on dalvik runtime, but if you were on art runtime nobody would even check your log. ART became official and fully stable in lollipop... i truly think that f2fs can become more stable but i don't actually know when. At this moment ext4 has nearly the same performance as f2fs but is times more stable. It is not worth spending this stability for such a performance upgrade.

ART became official and fully stable in lollipop... i truly think that f2fs can become more stable but i don't actually know when. At this moment ext4 has nearly the same performance as f2fs but is times more stable. It is not worth spending this stability for such a performance upgrade.

I find F2FS absolutely stable, and I don't know in what manner it could compromise stability.
ART is working amazingly well in my Moto G, so I don't agree when you saying it's an experiment in KitKat. The fact that ART is choking for our GNex, doesn't mean it's an experiment. Are you a Google engineer to say that ART is fully stable in lollipop?. I think it never won't work smooth in our devices.
You defend EXT4. I defend Dalvik
