How can you say that ? For me it was the exact opposite when switching from this one to speedmod kernel ! Did you activate all the four recommended tweaks ? Or lagfix ? I really can't imagine a kernel that is "so much slower" than this one, hell even stock kernel is faster for me ! And with both camera and video playback working lolz

Really I'm not complaining but just trying to understand, maybe I've done something wrong :(
[Galaxy S I9000 Android Development] zurchpet:
@lastufo:

I have a suggestion: For those things that are just enable/disable like ramzswap and VFS, why don't you add TWEAKS for it like the SpeedMod Tewaks in the recovery to enable/disable it. No fiddling with init.d scripts unless you want to change parameters that are not only enable/disable a feature.

Just a thought.
[Galaxy S I9000 Android Development] laststufo:
I have not any usb reboot
[Galaxy S I9000 Android Development] Godenel:
Sorry. I will try it again in a few minutes. Maybe it was the bad version.
[Galaxy S I9000 Android Development] Godenel:
Now it works, thank ya all :)
[Galaxy S I9000 Android Development] vukandric:
Just to say that the version 3_3 works for me too. :)

No problems so far. I had voodoo before, but I guess that this kernel overwrote it, and my quadrant score is about 1500 now? Can I apply some other lagfix over this kernel or not? Sorry for noob questions, but that's the point of forum isn't it? :D

Thanks! :)

EDIT: Nevermind, just run it again and now I have about 1600. Still it isnt close to 2000+ like some others have, but its very responsive now.
[Galaxy S I9000 Android Development] laststufo:
With this kernel i got from 1980 to 2050 on quadrant
[Galaxy S I9000 Android Development] eliazu:
which lagfix did you use?

Since I only have a Mac and no space for Bootcamp/Windows my request is:

Could you build a update.zip version, to flash the kernel via CVM?

Great kernel btw.
[Galaxy S I9000 Android Development] kara mustafa:
But how about battery drain? The changes, which you have done, has a impact on battery life? I am asking about v3.3
[Galaxy S I9000 Android Development] kmrdeva:
I've applied the latest 3.3 optimized kernel on top of the 0.3 universal lagfix kernel on top of my JPM firmware. No errors from Quadrant, score was 1537.
[Galaxy S I9000 Android Development] kara mustafa:
And how about ClockWork recovery, does this kernel cooperate with CWR?
[Galaxy S I9000 Android Development] hardcore:
@laststufo: Just realized that if you compile with O2 you get about 1MB more RAM free, and with Os you get about 2MB more RAM free (maybe because kernel is smaller).

I'm testing the speed and it doesnt seem to be slower than O3 either.
[Galaxy S I9000 Android Development] ashwinds:
Look up the Heimdall project on xda. Enables flash from Mac provided you have installed JPA at some point (need not be ON JPA - just need to have done it once)
[Galaxy S I9000 Android Development] RMonst3r:

[Galaxy S I9000 Android Development] Guzmanus:
What problem is there with the camera? I need the camera today too
[Galaxy S I9000 Android Development] hensk:
are you using latest kernal

If you`re on it ,only open camera application & you will see

if you have it,dawnload another kernal
[Galaxy S I9000 Android Development] tzfrantic:
camera does not work nor video either also how can you use the scripts
[Galaxy S I9000 Android Development] suntzu123:
There should be describtion how to use it.

lol seriously , wonder why use a kernal in the first place then

what r u working on laststufo ? asides from the fast cam fix
[Galaxy S I9000 Android Development] _PrEzi_:
I DON'T believe the kernel to be slower than stock - virtually impossible. It IS the fastest & best on the market !

4.7.2 - screen flickering between blue and yellow color tone

I have made a little change in S_LCD_Color_Gain.sh

echo "256 256 256" > /sys/devices/platform/s3cfb/LCD_color_gain
echo "[b]256[/b] 256 256" > /sys/devices/platform/s3cfb/LCD_color_gain_low

but screen still seems a little bit "yelowish" with a very little flickering.

Going back to 4.7.0 where screen colors were OK...
[Galaxy S I9000 Android Development] vanahaim:
Absolutely the same in my case..
[Galaxy S I9000 Android Development] nanu_x2:
+1

10char
[Galaxy S I9000 Android Development] developer58:
Tnx for the update.

All working great now!
[Galaxy S I9000 Android Development] laststufo:
The flickering happens because of low screen freq equal to 25hz.. This go away if you elevate it.. The color flickering is a ploblem that i have to solve
[Galaxy S I9000 Android Development] laststufo:
I have to solve the color flickering bug.. And add to new things on VSF..
[Galaxy S I9000 Android Development] vanahaim:
Yes, I thought too, but the problem remains even if I set the frequency to +/- 45 Hz. With version 4.7.0 (with the same settings) is everything ok.
[Galaxy S I9000 Android Development] azuresystem:
i had a question here and wondered if it rings true, is sgs vsynced?

and if so can it maintain 60fps when ui browsing?

just wondered if theres been any attempting at syncing out refresh with actual fps rather than the maximum cuz if they arent a match youd get framlocked at 30 which would make the ui stutter, not that i see this alot but a good example is using twlauncher in the appdrawer and thats usually perfectly smooth when scrolling horizontally, on the other hand adw stutters nastily even tho it feels way smoother when browsing homescreens

anyone had the same with really sensitive eyesight?

//cheerz and keep up the good work!
[Galaxy S I9000 Android Development] developer58:
Doesn't happen at 40 Hz with me.
[Galaxy S I9000 Android Development] hensk:
flashing now &

report hire testing result
[Galaxy S I9000 Android Development] AmunReify:
Happens while VSF is disabled...
[Galaxy S I9000 Android Development] touness69:
Well... maybe to improve the performance of my phone ?? o.O guess it is... logical

But this one was too buggy for me when I've tested it and I'm fine with speedmod now, and the developper said that I have a problem so.. well thank you and good bye

Maybe when VSF will be disabled by default, the 500Hz value will replace the current 300Hz one and all known bugs fixed I will give it another try
[Galaxy S I9000 Android Development] hatori:
You have to put that script in init.d then reboot to fix the flicker problem.

It work for me.
[Galaxy S I9000 Android Development] laststufo:
When this kernel will speedmod... When the pigs fly... Stay where you are... That is too complicated for you...
[Galaxy S I9000 Android Development] touness69:
But the thing is that speedmod lacks OC :(

But the pigs can stay in their farm and you can just up your value from 200 it will be the kernel to have since then. But from now I have some hang ups randomly with your kernel without knowing from where they come and that s what borred me

and for the complicated part, the first post is well detailed and with xan's app it's nothing unreachable from my modest knowledge :)
[Galaxy S I9000 Android Development] Gembol:
Well, I think you should think about lots of people running this kernel without bugs, smoothly and fast... Then, think about if the problem is from kernel or is yours...

This is a perfect kernel IMO... 38% battery use in a whole day with average use (85 min total conversation, wifi 20%, 35 min GPS...)....
[Galaxy S I9000 Android Development] IntExCZ:
I have no problems with "autorun" scripts so yes, I put it together with VSF disabling script into "init.d" and they were executed. But still there is a little (very little) flickering and "yelowish" screen which is not in 4.7.0.
[Galaxy S I9000 Android Development] manageri21:
You are a kernel developer? NO, shut up ok, because a developer like laststufo, ect we need, if you like just one, stay over there.
[Galaxy S I9000 Android Development] All Day On XDA:
Set clock speed by command line

I want to be able to change clock speed through the command line.

Is it possible with this kernel?
[Galaxy S I9000 Android Development] mazroui:
wish u all the best laststufo

(touness69)first said the original kernal (stock one) was faster then contradict O_o

whatever makes u happy bro

using the phone i noticed a small stutter and wonder whats causing it(almost everywhere) playing games, taking videos/pics...... but hardly noticeable when just moving around the menu/browsing... yet again noticed both soft keys need a click or 2 to actually give out a command (little lag i suppose but i can live with it)

running on ext4 with no ext2 dataloop and an ext4 /system (noticed a big diff(more smooth operation) all thanx to /system on ext4)

I would very much appreciate if anyone here thinks his phone is crazy fast and could post a utube vid showing it..... i remember there was a video posted in the oclf/voodoo old posts that was seriously ridiculous fast mentioning ext2 but cant seem to find it

iv got like a total of 1000 sms/mms combined in inbox + about a 100 apps and 3 homescreens running launcher pro with page one (cpu monitor, ram, control widgets, batt......) middle with minimalistic widget loaded showing time/weather on a 3 hour update interval + batt percent and last screen showing facebook widget + a few news apps(xda,engadget.....)

normal phone use runs with like 90-120mb free ram

got 4 spare batts (2x 1500 and 2x 3000) so batt life aint an issue anymore, its all down to squeezing max performance from here on
[Galaxy S I9000 Android Development] manageri21:
About battery the difference of 3000 with 1500 on life time?
[Galaxy S I9000 Android Development] touness69:
O.o why talking **** like that?

Shut up ? Can't we give advice to developpers to improve their developpement ? Try staying cool buddy I weren't flamming his huge work.

@mazroui,

Are u blind ? Seriously where do you see a contradiction in what I have said ? O_O

Lolz , u got a point on what u said after, it seems like there is some hang ups ramdomly at some places in the interface and on apps, that's what I was talking about in my previous post. Hope this will be fixed :)
[Galaxy S I9000 Android Development] manageri21:
lastsufo now very well the hardcore kernel i think and so to tell him look what hardcore release is not advice for me, is request. if you have a solution for something sure is advice for him.

[Galaxy S I9000 Android Development] IntExCZ:
Yes, if you want it enabled...
[Galaxy S I9000 Android Development] FuryriderX:
I have this flickering as well....it seems to be related to processor frequency - if i disable the overclock i dont notice it, but at 1200/1300mhz its rather obvious.

stock_mem_timings, disable_vsf and lcd_color_gain scripts are all in the init.d folder.
[Galaxy S I9000 Android Development] laststufo:

[Galaxy S I9000 Android Development] laststufo:

Last request / Idea

There is a big issue with our I9000...its the BT connection. We are able to pair but not to auto-connect. So we are not able to use saving software to mute BT on calls only. Is it possible to put a property to allow auto-connect on BT?

Hugs
[Galaxy S I9000 Android Development] chadouming:
yeah, i was just saying you were insanely good :p and as i study computer science (translated from google, not really sure its good ), i hope i'll be able to do some thing like this.
[Galaxy S I9000 Android Development] laststufo:
Could you explain it in details with a concrete example.. tnx
[Galaxy S I9000 Android Development] chadouming:
hmm, i think i can provide you an example for this. With my last phone, i had my car stereo paired and when i came in my car and my bluetooth was actived, the phone was auto-connecting and when i started music with my phone it autoplayed on my car stereo. With the Sgs i have to do setting -> Wireless -> bluetooth -> connect and bla bla bla. Correct me if i'm wrong.
[Galaxy S I9000 Android Development] FuryriderX:
I fixed the flickering problem i was having.

It had to do with the LCD color gain values....the 'high' was 255 255 255, and 'low' was 240 255 255. changed it to 255 255 255 and bye bye flickering!

Looking forward to tomorrow's release! Thank you laststufo!
[Galaxy S I9000 Android Development] mazroui:
Not as much as having 2 batteries but a rough estimate would be 1.5-1.7 times better/extra juice

And on low usage it lasts forever lol tho I simply can't use my phone like that
[Galaxy S I9000 Android Development] IntExCZ:
Yes, "big flickering" is gone but if you look close (mostly seen on white popup menus) there is still some soft "yellowish" color tone flicker.
[Galaxy S I9000 Android Development] hatori:
Eagle eyes, for me I can not noticeable. :)
[Galaxy S I9000 Android Development] IntExCZ:
Use internet browser and look on white/grey areas of the page ;)
[Galaxy S I9000 Android Development] martan1981:
yellow

Yes this yellow tone is very noticable and very annoying, please fix that.
[Galaxy S I9000 Android Development] FuryriderX:
I think the flickering must be caused by the 'high' and 'low' color gain still being used even if VSF is disabled, since changing the gain (mostly) resolves the issues.

If VSF is 'disabled' by setting the high and low frequencies to the same (60), and not by actually disabling the switching - the 'high' and 'low' gain are being switched back and forth at a completely random interval, because their triggers are the same. Perhaps this is the root cause of the flickering?
[Galaxy S I9000 Android Development] martan1981:
You are right. I changed the values for low color LCD and the yellow tint is gone.
[Galaxy S I9000 Android Development] djkoa:
BT

Most of the Nokia hand-free devices only try to establish connection after engine is on for a couple seconds (search ocurring from hands-free side). And on this case BT works fine. Still...if u turn BT after those seconds...it pairs..but doesn't connect. I always need to force a connection by going to settings>BT>Search>Pair>Connect. I believe to solve this issue is just the kernel to be patch to allow pair...and then connect if pair. I try many settings on the bt conf files...(there is a folder with those settings)...and there is a auto-pair "blacklist", etc.

Curiousity: i have also a Tytn-II...with a CM6.1 ...and it works fine. So i really guess has something to be with kernel...or bt driver :s

hmmm...u think there is "hope"? :)

[Galaxy S I9000 Android Development] suntzu123:
Need a little of help from you....

I just got nice idea. CPU is scaling when Im using it... But what I can see even if it used just little it going to 200MHz....

... So why it can't do it at 100MHz?

I just started to work with thershold settings. Guess that SetCPU would be perfect... But SetCPU can't save anything at conservative scaling.

Default up threshold is 70% and I'm sure it would be much better if I would set it to 90%-95%.....

down_threshold is 30% I think 40% should be better.

But I can't change anything.... What to do?

So I wrote sh command and put it to /etc/init.d/

echo "90" > /sys/devices/system/cpu/cpu0/conservative/up_threshold

-> not working :(

Laststufo, great work again!

So nice colors...ale maybe due to "placebo" effect...less yellowish! :D

I have tried the VSF again and....I'll give it a chance.

Now would be good to remove the bottom bright line :p
[Galaxy S I9000 Android Development] FuryriderX:
I have this exact problem as well. If you find out a solution please let me know!

Ondemand freezes my phone every time i use it. So i don't. There's even a little disclaimer in the menus of setcpu that the 'ondemand' governor doesn't work well/is unstable on the galaxy s phones.

Having problems with the init.d scripts too - they dont seem to apply always! For example, the disable_vsf script is supposed to set a value of '2' into the 'vsf_enable' sysfs file - but every time i go in after a restart the value is '0'. Do i delete the .sh extension? Or leave it?
[Galaxy S I9000 Android Development] laststufo:
vsf_enable ---> 2 : REQUEST STOP

0 : STOP

on SO 4_7_2

anyone tested ext2 lagfix ?

i was trying an ext2 on data and jfs on the other 2 / no data loop (ext2,jfs,jfs,false,false,false,false)

after system rebooted everything was good , i restarted to check on /system and it showed me (ext3,jfs,jfs,false,false,false,false) and wanted to redo the lagfix like i originally chose ext3 instead of ext2

whatever happened to ext2? is this a bug?
