yes we plan to get all to this device soon :)

as i told u guys (during the donation stage), we will try n bring all our projects (from other devices) onto this...
[Samsung Galaxy SL i9003] manrock111:
i have a request can you make a kernel with underclock 200 mhz frequency and 1 ghz as Max. + Gpu clock at 250mhx...

somehow i really don't know GPU clocking or not(i can just feel more smooth scrolling but not a big difference in Games or Video playback)

Reason for this: HUGE battery drain

i have test many devices with many overclock kernals with given governers.

i find, with smartass v2 battery give good backup even its on overcloking

but as we know this kernal are in testing phase i want to see what

200mhz min +1ghz max of CPU with smartass v2 do with 250 mhz of GPU?

May be a it provide satisfied battery with performance. So daily phone user like me also enjoy your this work who needs phone on work without charging.

:)
[Samsung Galaxy SL i9003] amit864:
test UCv6, as of now no stability issues.

setcpu stress test working well.

720p mkv sample not playing well (software decoding on mobo player, as expected).

Camera videos taken are playing well at 720p (mobo player, Hardware decoding).

CIFS working, Games working.

Don't care about battery life (with the phone lasting over a day for me)

Why was the V5-test6 fix so special? I do not notice any change from v5test6 to v6.

I assume that smartassv2 is working better than before.
[Samsung Galaxy SL i9003] DooMLoRD:
i tried making kernel with underclock but it doesnt boot or reboots after 2 mins of bootup..

we will see what can be done..

in v05-test6 i had implemented few hacks which i felt might improve GPU overclock performace...
[Samsung Galaxy SL i9003] nail16:
@doomlord

can the i9003 use different gpu drivers form other devices with the same chipset, as i no longer have my i9003 i can't test this but i'm sure that changing drivers help cause I'm using the i8150 drivers in my samsung galaxy s plus and theres a huge difference in fps, may be instead of overclocking gpu change of drivers can boost the sl :)
[Samsung Galaxy SL i9003] DooMLoRD:
samsung galaxy S+ is a MSM8255 device (and so is i8150)...

we will need to find compatible libs for i9003...
[Samsung Galaxy SL i9003] kenny43:
I was looking around and i saw an app called "Voltage control" the developer name is darek.xan, for what i understood it allows to control cpu clocks, I/Os, cpu voltage, and even the gpu O. O so i wanted to suggest, could we make our phone compatible with it?

I was helping someone in the Q&A and had to look a bit to find the links to v5. can you link them, from page 34, in the first post? we're testing for a wifi error on his phone which I dont have on mine, but we're using different versions of the kernel. I already gave him the link, but for those wanting v5, it would be easier to see it on the first page ;)

Doom/Napstar

I've have been noticing a minor bug since I first tried v4.. I've always just shrugged and never minded it but after a few weeks of flashing and testing I would like to report it.

Sometimes, when I select shutdown from menu via power button or shutdown phone option via CWM instead of shutting down, the phone restarts.

It just got annoying because I decided to start test a custom ROM today and wanted a completely clean slate, so:

1. I flashed XXKPE 2x, factory reset 2x

2. I flashed XXKPQ 2x, factory reset 2x - no problem up to this

3. Finally, flashed UC-v6. When I selected shutdown during first boot (to go to CWM and do a factory reset), there it is again. Instead of shutdown, the phone did a restart. After vibrate it booted again.

I just shut the phone down via pulling the battery from this point and just proceeded with the custom rom so no real problems.

I just thought it was peculiar that the phone behaved that way after flashing UC. (Not consistently, just happens from time to time --enough to make me think its UC not the FW)
[Samsung Galaxy SL i9003] ivAnash:
How do u check the cpu temperature now that it has been overclocked.. I tried several apps but none of them display the CPU temperature..

I mailed the dev, and according to him the "temp" file in the /sys folder which us required to check the cpu temperature is missing.. Could anyone confirm that..
[Samsung Galaxy SL i9003] amit864:
using setcpu to see temp.

[Samsung Galaxy SL i9003] ganeshbiyer:
@Doomlord could you release the UC kernel with latest cf-root by amit.

Many of the problems have been ironed out in the new cf-root release.
[Samsung Galaxy SL i9003] DooMLoRD:

hello everybody i m new to android just bought an 9003 and want to use this kernel but my info say i have xxpn firmware... (original italian one 2.3.5) can i just flash this kernel following your istruction? and if not what's the easy way to don't lose anything and to use this kernel?
[Samsung Galaxy SL i9003] ilcorsaronero:
if you're on stock gingerbread (IT), the easier way to upgrade without loosing data is:

* root your phone via doomlord method (works up to 2.3.5, you have 2.3.5) which does not require flashing

* make a full backup with titanium backup (set your backup folder on an

external sd card

)

* remove your sd card

* boot in download mode

* flash wathever you want through odin

* wipe everything (just to be safe)

* install titanium backup and restore
[Samsung Galaxy SL i9003] tariq_devil:
So it just increment the things in my mobile, does it create any damage since it overclock itself? Can i flash it now as i am currently on xxkpq

anyway the backup will restore all the apps installed.. and widget.. everythink?

I have xxkpn to move to xxkpq i have to flash first via odin the full rom and then only the kernel right? sorry for this stupid question but i m new to android phone and before i make it like a brick i m asking

thanks
[Samsung Galaxy SL i9003] ggclanlord:
Flash XXKPQ as PDA.

Data won't be deleted but still make a backup to be safe.

Then flash this kernel as PDA.
[Samsung Galaxy SL i9003] supertommy82:
sorry sir what do you mean to "AS PDA" ?
[Samsung Galaxy SL i9003] jamsori:
Put it in the PDA field in Odin.

If you still don't understand, don't do it - too risky.

[Samsung Galaxy SL i9003] supergaijin:
so you're running 100% stock except the kernel? or are there other things that may cause it (custom rom, theme, etc.), that you're using but haven't excluded by testing different things first before declaring it's the kernel's fault?

[Samsung Galaxy SL i9003] bigeyes0x0:
@jesrani: Supposedly it should work, as I checked /proc/filesystems and I see ext4 there. So this kernel might have working ext4 support. I can't be sure though, better ask DoomLord.

are u sure that you re using latest kernel? (FIX1)?

have u allowed SU access to that app?

also i would like to tell u that as of now (v01/v01-FIX1) i have just merged stuff from my existing repos (which are for Qualcomm Snapdragon devices)... so some governors might not be fully optimized for this platform... but that can be done.. currently my aim is to add as many features as i can from my existing sources from other devices... once all that addition is done we will later work on optimizing and fixing small issues...

Booted without any problems.

As per you there is no EXT4 support.

So how come I did not have any problems booting up.

How?

all of these governors/schedulers can be tweaked to ur liking/usage/workload...

How to move from UCv6+XXKPQ to UCv6+DDKP2

UCV6+DDKP2+EXT4
[Samsung Galaxy SL i9003] deepanshu sharma:
do we need to convert to ext4 seperately after flashing this kernel??
[Samsung Galaxy SL i9003] joelmonty:
Yea, i faced this same problem before also,i was on stock XWKPG and now in XXKPQ ,the same problem has come back,and the issue's get rectified when i flash stock kernel,and i noticed that fruit ninja works with lags in v6 ,other versions used to work properly ,i will confirm later.
[Samsung Galaxy SL i9003] inciongd:
If you are already in EXT4 before flashing, no. If you are from a fresh stock rom flash yes.

Flashing only the kernel wont have an effect on the current file system format your phone is using.

This isnt the thread for questions BTW, please ask next time in the QnA thread. :D I asked in this thread like you when I first started, but now I ask only in the QnA.. This thread is for feedback to the devs :D
[Samsung Galaxy SL i9003] supergaijin:
check what the guy above this post said. you need to have cwm installed, and convert to ext4 if you're using these kernels ;)
[Samsung Galaxy SL i9003] tariq_devil:
Can i directly flash this kernel in recovery mode? I am currently in Poseidon rom xxkpq, rooted and deodexed.
[Samsung Galaxy SL i9003] joelmonty:
I have cwm installed ,to get to stock kernel i just flash amit universal cf root ,and if your telling that the lag in caused is by rfs file-format that's wrong ,because im on ext4 ,these problem are related to UC Kernel, because when i flash amits cf root ,i don't have any kinda issues.
[Samsung Galaxy SL i9003] falex007:
No you can't apply it with CWM. But you can install Mobile Odin and flash the kernel by it
[Samsung Galaxy SL i9003] deepanshu sharma:
backup and restore is not working while i try to convert it to ext4!
[Samsung Galaxy SL i9003] |DM|:
Not true.

I just did it today, XXKPQ with UC 4, and it works fine...

It's a problem of your modded ROM

Anyway I think that the GPU OC doesn't work realy, because the differences between UC 4 and UC 6 are realy little ... I don't know...
[Samsung Galaxy SL i9003] deepanshu sharma:
i tried with v6 on DDKP2 but it didn't work

[Samsung Galaxy SL i9003] HeathenMan:
I was getting VERY high temperature until charging+surfing (interactiveX, uc 06) - thats too much! :P the whole screen is hot
[Samsung Galaxy SL i9003] inciongd:
If you are getting error while restoring /system during ext convert make sure you have 500+ MB free on your external sd.

If you still cant restore, reboot cwm after ext4 format via advanced menu.

Another way-- flash ucv4, ext4 convert and then flash ucv6.

If you are getting any other error please post it. Its better to give the error you get than to just tell your general problem.

Also, if you get lag when using custom rom, play with the tweaks menu. Some tweaks there are redundant/incompatible with built in tweaks of custom roms.

High temp is because ucv6 has cpu and gpu overclock. Please expect it, oc is one of the goals of uc. Use v3 if you dont like overclock. Also i think doom/nap will release stock freq kernels in the future.

For those trying DDKP2 here's what worked for me:

XXKPE

DDKP1

DDKP2

UCV4

EXT4

UCV6

Titanium restore user apps only

Also, the touchscreen tweak i found in this forum seems to work nicely. I'll post a link when i get to a pc.

[Samsung Galaxy SL i9003] Misledz:
Another weird find.

-Using UC v6 caused hyper phone lag and was somehow unbearable in the long run.

-Flashed to UC v5 and the phone lag dropped, was semi smooth tbh.

-Reflashed UC v6 to see if the lag was still there, this time it was smooth as hell?

I think the Nvidia script inside the v5 has a positive effect towards the phone? Currently not experiencing any issues unlike before.

Ok back to topic.

Doomlord somewhere I read that multitasking depend upon kernel. As u are expert in kernel coding, can u make changes in kernel so that we can have best multi-tasking without auto-closing of app due to low resources or anything like that...? Its really frustrating that android auto closes every app because android os think that we dont need it because we have not used it for longer time. In symbian multi-tasking is much-much better.
[Samsung Galaxy SL i9003] inciongd:
Visahal,

Im not sure but i think google implemented this as a feature in gingerbread. I think i read somewhere that to improve battery life, google made idle application culling more aggresive. If you want to try, maybe apps stayed longer in froyo than in gingerbread. So i think the reason is more power management than memory or something.

This should just be a timeout parameter somewhere and not hardcoded into the kernel. Idk if its correct, doom?

I think if it is just a parameter, then it should be implemented by cf-root tweaks menu. Maybe a slider there to adjust the parameter.

Sent from my GT-I9003
[Samsung Galaxy SL i9003] vishal24387:
@ Inciongd

dont know but i think its not that simple. Otherwise brilliant galaxy S or nexus developers already would have done changes in os to make multitasking effective.

I read that in GB resources allocation is different that in eclair. In eclair u will get real multitasking like in symbian. Means application never auto closes in eclair. But in GB due to resource allocation system, it take out ram if it think that user is not using that app for longer time & auto close the app. Then it gives that ram to currently using app.

But who take this decision that which app will get more priority for resource allocation? I think its kernel (may be I am wrong).
[Samsung Galaxy SL i9003] Erahgon:
The "RAM min free" tweak in CF-ROOT could be used. Basically it keeps programs in RAM for much longer, keeping its usage high throughout. Doesn't have many adverse affects unless you game a lot or something. If you use the same few apps in a session, you would notice better multitasking and less app hangups.
