doom please can u check wifi problem in KPM only that is the problem other things are working quite well..!!
[Samsung Galaxy SL i9003] mjbri0613:
@doomlord is this kernel has ext4 support? thanks for this kernel..
[Samsung Galaxy SL i9003] ganeshbiyer:
@doomlord

Could you release only the kernel without cf-root.
[Samsung Galaxy SL i9003] podanimesh:
I have a great news this kernel fixes the bug of not charging in Power OFF mode..
[Samsung Galaxy SL i9003] mr_alone_hvtt:
I'm on xxkpq, after flash, phone reboot when I turn on wifi, fix prob pls
[Samsung Galaxy SL i9003] manrock111:
I have flashed your kernel and stuck at bootloop(now back to BAM kernel), i know its normal and i need to install fresh KPQ. Anyway current kernel is immature not worth flash my whole data.

Till then I'll stay tune to you :) thanks
[Samsung Galaxy SL i9003] vishal24387:
problem is already mentioned. Dont repeat it agan & again.
[Samsung Galaxy SL i9003] shriom_manerker:
did fresh install KPE>KPQ>ur kernel

worked fine but as soon as i start wifi it reboots and it boot loops since the wifi doesnt get disabled after reboot :\ it reboots as soon as the vibration is felt ! fact reset and it works again until u start wifi
[Samsung Galaxy SL i9003] DooMLoRD:
UC-Kernel v01 - FIX1

this will resolve the issue of wifi

[ info ]

seems few of the n/w related tweaks that i had merged into sources is causing issue with wifi...

no problem i have reverted to older sources which dont have those tweaks... rest of the governors and schedulers are intact...

[Samsung Galaxy SL i9003] podanimesh:
@shrimohan man this problem is stated 4 times in this thread please go through it.

@Doomlord can u please mane a bug list in OP so that same bugs are not repeated in this thread.

ONE more thing tried this firmware on KPM worked fine now wi-fi is also working and everything else also works..i think this is due to universal CF-ROOT.

see this
[Samsung Galaxy SL i9003] DooMLoRD:
sorry i only have XXKPQ to test....

not at the moment but i will add lots of FS support in next release

u know how to get the zImage out... why u want w/o CF-ROOT though?

i dont like ur tone of calling anyones work "immature"... there are numerous reasons for being stuck at boot/bootloop...

bug is fixed in new release v01-FIX1
[Samsung Galaxy SL i9003] ooikaisheng529:
doomlord please kindly tell napstar to edit his post at the first page when he logs on so no people would download the wrong file and complaining about the wifi problem again
[Samsung Galaxy SL i9003] vishal24387:
guys give some time to them. Dont run behind them. They know very well how to maintain their posts.
[Samsung Galaxy SL i9003] DooMLoRD:
yes i have told him but he is busy with some work... he will update his post when he gets time...

@ALL

i would really appreciate of everyone stops snapping at each other... its ok relax guys, chill and calm down...
[Samsung Galaxy SL i9003] manrock111:
there is nothing to worry about "Immature" word :p

This is the main problem of text communication you never find out what is tone or feeling of person who wrote things.

I respect you as a dev but i am not do False Hails or feedback.

If you still think immature is not right word to wright or it hurt your feelings for your work

then i will say it "not enough stable due to its pre-mature stages"

i hope you understand my feeling now :)
[Samsung Galaxy SL i9003] jesrani:
@DooMLoRD, any chance that you would make kernel for DXKP9?
[Samsung Galaxy SL i9003] DooMLoRD:
you should be more careful the way u put forth ur words...

constructive criticism is always welcome....

try v01-FIX1 it will fix ur issue, the reason u had bootloop was that ur wifi/bt was active from old flash... now that issue is fixed...

[Samsung Galaxy SL i9003] nail16:
what are the hacks can you please be specific? cause i don't know what to check in these new test builds??
[Samsung Galaxy SL i9003] DooMLoRD:
the hacks are related to the GPU driver in the kernel sources...

we are right now testing GPU overclocking...

so run some benchmarks, play some games and let me know if there was any improvement...

also do let me know which version performs better...
[Samsung Galaxy SL i9003] deepanshu sharma:
i've checked the v5 test 6 and works good.have played modern combat 2 and have seen significant changes.there is almost no lag in it.will check test 5 and 4 tomorrow.

anyway...i want to ask whether this overclocing REDUCES the cpu's or gpu's life??
[Samsung Galaxy SL i9003] DooMLoRD:
yes any type of overclocks CPU/GPU decrease the life of these chips...

BUT most of these chips are designed to work for 5+ years (may be even more), so even if it decreases life, by the time the chips gets permanently damaged, u would have bought a new phone ;)

also keep in mind these overclocks are always active for short duration as most of the time the device will be in deep sleep...

so in short dont worry :D
[Samsung Galaxy SL i9003] joelmonty:
Flashed the v5 test 1 ,getting random reboots,after reverting to v4 ,random reboots gone ,any one facing this issue?
[Samsung Galaxy SL i9003] nail16:
doom i'm running test 6 build and now games are more smother than before modern combat 2 doesn't lag any more and there is a significant increase in fps thus improving the gameplay and is more responsive, while playing asphalt 6 i saw large boxes (pixels) in some of the tracks i don't remember if they were there before, samurai 2 tegra works perfect whit nvidia plugin.

hey does overclocking gpu increases game loading time? just asking cause i felt asphalt was loading a bit faster than before :)
[Samsung Galaxy SL i9003] deepanshu sharma:
@nail16

can you please tell if the game(asphalt 6) lag after test 6??coz it used to in stock and v4 kernel.
[Samsung Galaxy SL i9003] nikhilgavit:
Tested v5 test4 and test5.. played 9mm hd.. had no lag as such.. gameplay is smoother as compared to v4.. quadrant score jumped from 2232 to 2389 with v5 test 5..
[Samsung Galaxy SL i9003] nail16:
how come we cant see changes in nenamark. my fps is still 31, dam thes benchmarks cant be trusted.

@doom is overclocking to 300mhz possible ?
[Samsung Galaxy SL i9003] rascal0pl:
Shadow Gun is much smoother! - Test 6

Works fine @ KPM
[Samsung Galaxy SL i9003] jan3586:
Should I disable chainfire 3D with the GPU overclock kernel?
[Samsung Galaxy SL i9003] abrarabbu:
significant increase in performance

battery is same as stock

nice one

i had a wierd problem: phone wasent charging, had to flash firmware again. wierd..??

on v5 test 3..
[Samsung Galaxy SL i9003] DooMLoRD:
interesting... please keep testing, and kindly explain in detail when the reboot happens...

not all chips are equal, so each is uniqure and has different tolerances for handling overclocks...

thats why we need everyone to keep testing and reporting these issues (if any)...

graphics glitches are indications of the overclock causing issues... but that means the overclock is WORKING :)

yes faster CPU/GPU clocks means games/apps will load faster...

first lets make sure that the overclock we did is actually working :P

once we confirm that we can keep pushing the throttle up :)

Chainfire 3D is related to injecting an intermediate driver...

its a very interesting point actually... try testing out with both it being enabled and disabled...

hi generally when u get such issues just try and see if u get the same issue often and also check if u get same issue on stock kernel...
[Samsung Galaxy SL i9003] ooikaisheng529:
i think the overclock is indeed working, because many users have reported an increase in graphic performance such as games
[Samsung Galaxy SL i9003] leongwenjun:
at stock kernel also have this problem（while playing asphalt 6 i saw large boxes (pixels) ），not the problem of this kernel:p
[Samsung Galaxy SL i9003] fggarcia:
I'm testing V5 test6, all apps that incluide graphs has an improve performance. The only problem that i saw is 720p mkv file a little lag. You work is amazing. thks
[Samsung Galaxy SL i9003] abrarabbu:
Now on Test 6:

I Don't understand what hacks mean or what they do.

Phone is like speed. battery is good (btw 1650mah is more than enough, if we spent some mah for performance, it doesnt matter)

its stable.

looking for higher overclocks...

Was looking in data sheets.

just a thought if 4 tables are available, setting 300-32, 700-51, 1000-61, 1200-66(max) will be awesome.
[Samsung Galaxy SL i9003] josephtt23:
thx

thank a lot.,

i using UC-Kernel v05-TEST6

i see when i running the quadrant,the fps is higher,

thank a lot^^
[Samsung Galaxy SL i9003] Gamer2:
Is there any app/method to check the gpu frequency?

---------- Post added at 12:32 PM ---------- Previous post was at 12:17 PM ----------

Ok so i conducted a few tests and here are the results-

cpu governer- smartassv2 i/o governer- sio

tests conducted on an3dXL(i somehow dont trust quadrant)

stock(v 04) w/o chainfire- 17245

stock(v 04) with chainfire(nvidia plugin)- 18343

v05 Test 1 with chainfire - 19345

v05 Test 3 w/o chainfire - 19693

P.S. will conduct more tests later as m slightly short of time
[Samsung Galaxy SL i9003] joelmonty:
I was getting random reboots on v5 test1,then i flashed v5 test 6 ,no reboots now,everything working ,i tried some mkv 720p utilizes the HW and plays perfectly,and some videos don't ,same 720 mkv uses SW.

Major improvement in -

Fruit Ninja(stopped giving spikes and works smooth)

Modern Compact 2 BP(Spikes still there but less and smoother)

Angry Bird (stopped giving spikes ,works smooth as always though)

Air Hockey -2 players works good

And

Shadow gun- almost 5% less lag then before

Asphalt 6-works better 10%,but used to work good on v4 also.

@thanks for the boost in performance :-) .
[Samsung Galaxy SL i9003] ivAnash:
Using v5 test 6.. No stability issues.. Graphics are considerably better.. 720mp videos playing real smooth..

No significant battery drain.. Loving It..

Thanks doom..
[Samsung Galaxy SL i9003] DooMLoRD:
while testing use PERFORMANCE governor so as to remove the CPU scaling effects
[Samsung Galaxy SL i9003] ooikaisheng529:
Using v5 test 6, w/o chainfire3d, i got 20649 in an3dbenchxl using performance governor
[Samsung Galaxy SL i9003] mitoVonDido:
Using v05-test6 on KPQ-Poseidon rom.

I can see higher fps while testing antutu and phone speed now improved a lot.

I saw someone make 3d test with an3dbenchxl. My score: 20612; gov: performance, i/o: vr, without chainfire3d

Also didnt have any heat problem till now.

Battery drained is almost the same as stock one.

Im only testing fruit slice and angry birds game :p spiked free thus better performance now!

Thanks for this awseome kernel doomlord.

p/s: i cant use mobileodin to flash this kernel
[Samsung Galaxy SL i9003] DooMLoRD:
Hi while posting test results please give comparisons of using the same apps on stock and v04 kernel... Also use performance governor while testing....

That way we can be certain whether the changes made in kernel are actually helping improve performance...
[Samsung Galaxy SL i9003] ooikaisheng529:
Flashed v4, the an3dbenchxl score is 20599 compared to the previous 20649 on v5 test 6....now i'm not trusting any benchmarks anymore

[Samsung Galaxy SL i9003] rascal0pl:
DooMLoRD, i have a question.

When you finish work with GPU overclock, can you do something with video recording? but rather with audio quality ( reduce mic gain sensitivity and distortions - like in voodoo sound that is unsupported by our device)
[Samsung Galaxy SL i9003] KBS720:
Using v5 test 6: No issues what so ever.

My tests:

Asphalt 6 performs better, significantly fewer fps lags.

ROC has minimal fps lags. Minor ones are gone.

Using Xperia Arc Launcher 2.0 (fast corners version), the animations of the corners are smoother than ever. Before you could see the lag, but now its gone :)

Previously I was using live wallpapers just to prevent my homescreen from lagging even a tiny bit. Now normal wallpapers don't lag while scrolling (YAY! More wallpapers for me to use :D)

One easy test you can try:

While on home screen, press the menu key (left of the home button) and press settings.

Scroll to the very bottom with just one swipe and press the "about phone" option.

Do this as fast as u can :)

Previously, you sometimes end up pressing Applications or Accounts and Sync when going too fast. The phone can't keep up :(

Now, its flawless. I can scroll down to the bottom the the settings menu without any problems. I remember this performance when I was on froyo.

I've been doing this test for ages (even with other phones), and was more interested with v4 cpu oc. But that version did not meet my greed for speed XD.

v5 with the gpu oc was the one I was looking for :)

Great job DooMLoRD and UC!

Hello,

I would like to participate in GPU testing, but this is my first time rooting my phone. I have had this phone for only a month now, but I do have some experience with unix/linux from work.

I have a few questions:

1. I am on V5, do I need to un-root, re-flash XXKPQ stock and then flash V5-Test6? Or can I flash directly V5-Test6?

2. In CWM Recovery, does the backup also save the firmware? i.e. If is it a complete time state of my phone? I did 1 full backup in CWM, If I flash another firware and then I restore that backup, do I revert back to the firmware at the time of backup?

3. In which directory/where can I find the config files of Android itself or our device? Is there a .assets or .properties file for Android/our phone? I would like to tweak around as well.

Hope my questions are not too noobish. I am also reading a lot and will share if I have found answers on my own.

No just flash test 6 file.

Yes it backup whole files and data including firmware tweaks and all things. It's like snapshot of phone at the time of backup.

Whatever firmware you are, Restore will get back you to at the yime of backup?

3. In which directory/where can I find the config files of Android itself or our device? Is there a .assets or .properties file for Android/our phone? I would like to tweak around as well.

Use root explorer you'll find there are so many partition, start reading on net about it

Hope my questions are not too noobish. I am also reading a lot and will share if I have found answers on my own.

AT ALL THIS IS DOOMLORD FEEDBACK THREAD NEXT TIME ASK YOUR QUESTIONS IN GENERAL THREAD.

Thanks man, now running on V5-Test6. Smooth.

1 thing I found so far, USB connection to PC when USB debugging is ON not working for me on first try. I turned of USB debugging for the moment and used the MTP app to connect to my pc. Just copying some files, ill try if USB debugging connection works/make it work later.

Even after gpu nd cpu overclock

Live wallpapers make UI laggy

Even nexus one runs smoothly
[Samsung Galaxy SL i9003] amit864:
Using V5-Test6.

Antutu 2d : 285

Antutu 3d: 762

Where can I know my GPU overclock frequency? Antutu info does not show this information. Also, can I benchmark using GLBenchmark 2.1?
[Samsung Galaxy SL i9003] DooMLoRD:
Live wallpapers make the UI lag even on Arc @ 2GHz & SGS2...

It's because of the way android handles UI... Hopefully this will change with ICS, it will bring gpu accelerated UI...
[Samsung Galaxy SL i9003] deepanshu sharma:
but the chances of ICS are very less for us.fuss is our only hope.

no problem for me in usb debugging

using V5-Test6

in xxkpm
[Samsung Galaxy SL i9003] KBS720:
Not really (atleast for stock live wallpapers). I use the nexus or the blue soundwave spectrum live wallpaper and its not very cpu demanding.

Using live wallpapers makes ur cpu more active, thus, it is usually at a higher ramp frequency than using normal wallpapers, and making the ui slightly more responsive (especially scrolling home screens).

Some more feedback on v5 test 6:

I experience a weird scenario earlier.

I was on silent/vibrate in deep sleep mode when Smurfs notification went on and alarm triggered right after.

After I checked my phone I noticed it was hotter than usual. It was @ 44°C.

I monitored for a few minutes and the temp when down normally. This has yet to happen again.

I'm now slightly failing in my "Scroll to About phone" test in settings. Just some minor fails (although this could be due to my sweaty fingers and smudgy screen) but overall performance is still better than v4.

@Doom there's an lock screen time out bug on v5 Test 6,like when i put an alarm,after the alarm get over the the phone stay awake with lock screen and stays that way ,which causes massive battery drain and heat,i tested on stock kernel,this issues isn't there.
[Samsung Galaxy SL i9003] Napstar:
Please mention your CPU governor, CPU min-max policy. Since all governors are not optimized for our device as of yet.

So far, I have been able to optimize savagedzen governor for our device. I am attaching screenshots for battery performance for last night where battery drain is only by 4% in 10 hours. I dont know the stock kernel behavior but I have heard that savagedzen drains battery in previous releases.
[Samsung Galaxy SL i9003] vishal24387:
@napster

is it really difficult to optimize every governer for our device?? Generally how much time every governer take to optimize???
[Samsung Galaxy SL i9003] DooMLoRD:
well it involves adjusting/tweaking the sources and then testing if scaling is correctly working, and that it shouldnt crash the device... he is working on tweaking these things... dont worry at the end of the process u will get governors tweaked for this device :)

thanks we will try n recreate the issue on our device and check...

thanks but next time please send me & Napstar a p.m. :)
[Samsung Galaxy SL i9003] DooMLoRD:
small update

i have added two more govenors:

LIONHEART

LAZY

Napstar is testing these...

additional i wanted some info:

are most users ok if we continue work on future kernels with the 275Mhz GPU overclock (v05-test6)?

i think we have received 95% positive feedback with that test kernel... so i think we can safely use it further...

what do u guys think?

oh and btw once this is finalized we will maintain 2 stock kernels for latest firmwares:

CPU overclocked (currently to 1.1Ghz) + GPU overclocked (currently to 275Mhz)

Non overclock (CPU max at 1Ghz + GPU max at 200Mhz) [same as stock]

both will have all the rest of features so those who want great battery life can just use the non-overclocked version :)

P.S.:

do not ask for more variants (only CPU overclock or only GPU overclock)

yes will will update to newest available CF-ROOT

and yes there will be CM7 kernel soon when we finish optimizing governors and adding the feature we have in mind

you guys are lucky... you have got two devs working on this device by donating just one device ;)
[Samsung Galaxy SL i9003] DanteDMC:
CPU overclocked (currently to 1.1Ghz) + GPU overclocked (currently to 275Ghz) (Mhz)

Is it possible to implement a variable overclock ala XDA BAM's kernel? Then people would be able to choose their own config (CPU Normal + GPU Overclock, CPU Overclock + GPU Normal etc.)
[Samsung Galaxy SL i9003] vishal24387:
@ doomlord

thats why we donated a phone to u because we know that u & napster will really make our device superb like anything. Anyway ur plan about keeping 2 kernel is great. Because like many guys I dont play HD games. But in future if u can manage to make more cpu range in set cpu then definitely I will prefer OC version with also 1 ghz option available in set cpu table :):)

I am waiting for ur new kernels.
[Samsung Galaxy SL i9003] nail16:
