@vishal

Did u try different odin version?
[Samsung Galaxy SL i9003] loukalok:
@napster and doomload

Yes,crk. Is right. Some of users( face the blacklight issues) can not use the all aosp rom like miui,cm(7&9),it is about the kernel, but we only can wait, wait and wait.because we don't know about kernel ,like crk said, you can go to his thread and look the video, or logcat and kmsg,

Because I look into the kmsg. Txt

A line is different to the users( no blacklight) it is about the LCD

No blacklight: it is made by Hitachi

Have blacklight: made by Sony

Pls, can you two or other good at kernel look into the kernel and help us????????

Plssssssssssss :(
[Samsung Galaxy SL i9003] crk1995:
A CORRECTION IN YOUR POST..

Users facing blacklight issue have sony lcd..

and users without blacklight have hitachi lcd....

@Napster : I'm using Poseidon ROM and I tried v10, found wifi and GPS not working at the same time :(

if you reboot with both wifi n GPS switched on, wifi starts connecting but with out internet access..

This issue was there in v7 and v8 for me.

But v9 1009 has no such problems.

Can u please do the same to this release as in v9..

or is it like CANNOT BE with Poseidon ROM... !!??
[Samsung Galaxy SL i9003] Napstar:
We will try to correct it.

I will simulate same conditions on my device and then reply. But in device on state when I switched them on, I did not face any problem.
[Samsung Galaxy SL i9003] loneagl:
Can I flash it on a custom rom????
[Samsung Galaxy SL i9003] Napstar:
try it, and report here.

which rom are you using btw?
[Samsung Galaxy SL i9003] vishal24387:
@ napster

I think my phone problem is that it cant accept overclocking above 1200mhz. Because UC v9 1009 version kernel works perfectly for me. But any other kernel even vurrut kernel which is also OC greater than 1200 mhz for which my phone doesnt boot successfully. If possible can u plz give a test kernel having min freq 120 mhz & max 1200 mhz only with remaining all features of UC v10 kernel...??
[Samsung Galaxy SL i9003] Napstar:
Did the one i sent you few hours before work?

else, i will send you one by P.M. tomorrow. i am out of my work place now.
[Samsung Galaxy SL i9003] vishal24387:
the kernel u send me by pm doesnt wotk for me.
[Samsung Galaxy SL i9003] mitoVonDido:
I have the same problems with vishal..luckily I was able to boot on v10. It seems good until I changed the frequency to 1300mhz, then it hanged immediately. When restart phone, it freezed at sansung screen like forever. Apply back v9, then my phone boot well. Note that I'm also got the same problem with vurrut kernel. TQ

[Samsung Galaxy SL i9003] vishal24387:
thank god...someone has same problem like me.
[Samsung Galaxy SL i9003] Napstar:
Please un-check "set on boot" outrun from setcpu. We have told you guys that from start.
[Samsung Galaxy SL i9003] vishal24387:
I already did that but still bootloops. All devices cant handle OC above 1200 mhz.

If u provide test kernel with 1200 mhz max & 120 mhz min with all features of UC v10 then I am sure device will boot.
[Samsung Galaxy SL i9003] mitoVonDido:
Thanks napster. Already done that but still. To be sure, im flashing back to Clean stock, kpe->kpu->v10; it boot for the first time. Then im just reboot and now freezing at logo. Im not installing setcpu or any apps. Maybe its true that some devices cant handle freq above 1200mhz like mine :)
[Samsung Galaxy SL i9003] chongns:
Guys, i tought the kernel set default boot at 1ghz?
[Samsung Galaxy SL i9003] xarolx:
Yes, without apply any cpu control, its default at 1Ghz
[Samsung Galaxy SL i9003] earldroid:

[Samsung Galaxy SL i9003] robyguerrini:
Video don't work well whit this v10 on poseidon rom ..... used with video app and mx video player the result is the same.... long video don't work and short video work but with many difficult.

I've flashed many times and wipe cache and dalvick cache but don't solve this strange issue and i reflashed BAM kernel and video now work.... confused!!!!:confused:
[Samsung Galaxy SL i9003] anuraagkochar:
can i use v10 on miui v10.4 ?

is 1350 mhz stable for everyone ?
[Samsung Galaxy SL i9003] Napstar:
what was your cpufreq profile?

Because lower frequencies are expected to give problems with media playback or even Video recording.

Its fixed now, and fixed version will be released soon.

You will be able to record videos even at 120MHz frequency but obviously the device will be very laggy at that freq. ;)

(It had nothing to do with cache though. :P)

Current release is still not for MIUI.

And people are still testing higher frequencies.

I want more people to test this release, so as to have necessary corrections in next release.

Thanx

[Samsung Galaxy SL i9003] sirilpta:
I'm on DDKP3 stock with no themes..

with v10 when i open the camcorder and clicks on record it shows "recording failed" and freezes on that screen... tried with many combination of frequencies and governers but failed.... sometimes it starts the recording but after a long lag...

Also when i open camera it takes a long lag for the camera to initialize and open

EDIT: tried with 1, 1.1, 1.2, 1.3 Mhz but i failed to record video.

My phone successfully enters 120Mhz.

hope you will look into it...
[Samsung Galaxy SL i9003] xGiox:
this might be stupid,but i was thinking,if you could make custom rom whitch is based on stock,so do deodex zipaline ext4,14 toggles mode,custom lockscreens.no theming,and some tweaks if you want.my point is that we get one testing rom that we know it 100% compatable with uc kernel,even tho i would use it every day coz i hate this custom ones with ugly themes and bugges.
[Samsung Galaxy SL i9003] chongns:
Hi xGiox, are you at the wrong threat ?

here we are at UC-Kernal, not any other C-Rom.:confused:
[Samsung Galaxy SL i9003] xGiox:
i meant rom for testing uc kernel.coz uc kernel is not fully compatible with all roms out there,so might give false bugs,for example i have minor bugs with v10,phone is stable,but sometimes i get restart when i am listening to music and phone lock.and i cant report it because i am not sure is it due to rom,kernel or rom+kernel.if we had testing rom it would remove many false bugs.
[Samsung Galaxy SL i9003] chongns:
Yeah. U r right. However ppl r not listening.

srry again for ot.
[Samsung Galaxy SL i9003] alex88510:
Napstar and Doomlord build their kernel based on stock XXKPQ and they test on it.

So, basically stock rom could be called "testing rom". If you found any strange bug which other user doesn't have in their stock rom, it probably cause by ur custom rom.
[Samsung Galaxy SL i9003] sirilpta:
did anybody tried and succeeded in recording video with UC kernal v10...

pls inform here.... want to know that whether this problem is only for me or not....
[Samsung Galaxy SL i9003] hkh4all:
Already tried that...!! Also tried flashing the kernel twice... no luck...!!

The GPU Overclock that you have applied to your source doesn't work,

It doesnt show any difference in Nenamark2 nor in any HD games etc.

Same here. I tried a lot of bench/games, no difference

I saw that vurrut had remove it form vurrut kernel, For this reasone I think

[Samsung Galaxy SL i9003] |DM|:
realy ...with +50%of gpu oc we must see something like +30-40% off fps

+0.5-1 fps is related TO CPU oc or System usage
[Samsung Galaxy SL i9003] DooMLoRD:
i dont know why u guys are making such a big issue out of "gpu overclocking"....

we never said it worked 100%...

read thru the thread...

it was always "TESTING GPU OVERCLOCKING"
[Samsung Galaxy SL i9003] vishal24387:

VDD sysfs

Updates on current work:

Added VDD sysfs, which could read all voltage levels and a small lead in modifying individual bin from VDD table :D

Added extra intermediate bins in cpufreq table.

Current CPUfreq table offers;

120

200

300

400

500

600

700

800

900

1000

1100

1200

1300

1350

1380

Having seen few of users facing problem in using our last release, I thought of first taking care of VDD sysfs which should enable these people to play with voltage table and make their own device compatible for our kernels. ;)

Currently it is still in alpha testing stage.

A test kernel will be released soon.

But currently DooMLoRD will update kernel with some other features till we finalize VDD.
[Samsung Galaxy SL i9003] DooMLoRD:
just wanted to share what Napstar is currently working on:

userspace CPU voltage control!

proof:

currently he is able to set voltage for a specific frequency but he is still working on improving the interface...

please test out and let us know your feedback!

ENJOY!
[Samsung Galaxy SL i9003] alex88510:
flash v11 just now...

I set to 200mhz~1200mhz. So far no problem.

I found that the 1380mhz bin has been use for 10secs.

My phone can't handle frequency more than 1200 or it will have some problem.

So I wonder if this kernel is set to boot at 300mhz~1000mhz on default or it will just try to reach the highest frequency?

About the ZRAM thing, I enter the code in terminal emulator.

the free RAM not significantly increase, maybe slightly.

didn't feel any performance decrease.
[Samsung Galaxy SL i9003] DooMLoRD:
we havent implemented CPU freq thresholding at kernel level, currently its in ramdisk... so the kernel will boot up at max possible CPU freq before being throttled down to 1Ghz, as set in the ramdisk...

we will implement better kernel level cpu freq fix-up soon

all ur RAM wont be freed up immediately :p...

once ZRAM swap device is active it will take some time before new started apps can utilize that space...

i dont know for sure but i think some low memory killer settings/apps/scripts may not recognize the newly allotted zram swap so u may end up never using that swap space..
[Samsung Galaxy SL i9003] alex88510:
How to check whether the swap space has been use or not?
[Samsung Galaxy SL i9003] DooMLoRD:
u can execute the command:

(terminal emulator)

free

(adb shell)

adb shell free

this is from my ARC:

usually i used to have hardly 40-50 MB ram available... now i have 90-100MB+ :)

hence better multi-taking and ability to have more apps open...
[Samsung Galaxy SL i9003] alex88510:
what does this mean?
[Samsung Galaxy SL i9003] DooMLoRD:
only a few apps have started to use the new ZRAM swap device
[Samsung Galaxy SL i9003] alex88510:
I found that some apps are opening slower than before, is this normal because of the ZRAM?
[Samsung Galaxy SL i9003] shriom_manerker:
ok i flashed it today morning its been 9 hours and battery is on 74 thats amazingly gud since i used the device for 45 minutes :) everything is smooth but i found this one bug .. the camera app takes a long tym to load even if its a hot start it takes sum tym to connect to camera i guess ! it takes 8 seconds to c the preview of the camera live view and changing from still to video takes the same amount of tym ! video recording hangs from tym to tym on 720p then it hanged n fc for camera .. after opening camera app again it sas camera failed but i can c the preview behind this pop up message ! oh btw wifi works fine for me

m on stock ddkp3 deodxed

frequencies from 1.3 ghz max to 120 mhz min governor lionheart and io is sio
[Samsung Galaxy SL i9003] jan3586:
Happened to me too at 1300 MHz. When I set the Max frequency to 1200 MHz, the camera also takes a while to load but I avoid the "Camera failed" message. I am previously on UC v9 1009 and this used to work perfectly. Current setup is (same setup before flashing the kernel):

can u guys test if u have similar issues when using the device at 1Ghz MAX?
[Samsung Galaxy SL i9003] jan3586:
Hi DoomLord, Same issue at 1GHz. There seems to be about 7-8 seconds of delay. I attached a logcat in case it might help. Thanks for your effort.
[Samsung Galaxy SL i9003] alfovic:
im on kpq and evrything related to video doesnt work, also found that if i try to play a video with wifi on the status of wifi changes to error and i wont be able to turn it off

didnt have thos prob with v9

hope it helps!
[Samsung Galaxy SL i9003] sirilpta:
same for me too... camera takes a long time to intialize and video recording shows "recording failed"

in ddkp3
[Samsung Galaxy SL i9003] vishal24387:
now i come to know that why my phone failed to boot on every kernel which have higher frequency than 1200 mhz. 1200 mhz is the max freq that my phone can support.

@ doomlord

can u at least provide a init.d scrpit which will help me to boot at max 1000 mhz only & not more than that??? Its really painful for me that I am not able to use any kernel from so many days which has higher freq than 1200 mhz.
[Samsung Galaxy SL i9003] loSconosciuto:
It won't change anything.

At the moment every I9003's overclocked kernel (if I'm not wrong) make the phone boot at a frequency greater than 1GHz. The upper frequency limit is changed during the boot through init.rc and the change is even made before init.d scripts are executed. It usually takes few seconds, but, from what you say, they are too much for your phone.

You have to wait for a better implementation as DooMLoRD said.

If you still want to try with an init.d script, you can use this handy app: NSTools. It's made for the Nexus S, but it works great on our phone too. It allows you to create init.d scripts (you have to select the right option from the settings).
[Samsung Galaxy SL i9003] alex88510:
After seeing some feedback from other user, I test the camera.

At first, during initiate, it behave normal.

When I switch to front camera for the first time, it act strangely like it didn't connect to front camera but back camera and the pic is kinda funny.

When I switch back to back camera and re-switch to front camera again, everything normal.

Taking photo is normal, no delay.

But video recording is no go, shows Recording Failed.
[Samsung Galaxy SL i9003] XDA_Bam:
This is correct. Until the cpufreq driver is loaded and the value is set in init.rc, the phone will be running @ the highest enabled OPP (1.2 / 1.3 / 1.38 GHz, depending on the kernel). I'll see what I can do.
[Samsung Galaxy SL i9003] DooMLoRD:
works just fine... just tested... video recording start immediately... tested 720x480, 1280x720... then tested snaps/photos on both front/back camera all fine...

tested on XXKPQ - UC kernel v11

read the post u quoted...

i already told u the reason why it happens and i already told u that i am working on a better way to fix-up CPU bootup frequency...

right now i am merging the new sources (GT-I9003_SWA_GB_Opensource_Update1) into our kernel source...
[Samsung Galaxy SL i9003] alex88510:
mine also in XXKPQ, did you found any problem with the logcat from other user?

taking photo, open camera is fine for me but not video recording.

EDIT: attached screenshot of Video Recording failed, during taking the screenshot, found that the wifi become "Error".

I found another strange thing, which is, in SetCPU and No-frills CPU Contorl, I set the freq from 200~1200mhz.

During boot, it use the max freq which is 1380mhz for 10sec, you have already explain it.

But just now during testing the video recording, it uses the 1350mhz bin for 9secs.

And the wifi become "Error", same like before while I testing the V9 #3009 or #2009 test kernel, due to the phone can't handle the freq more than 1200, the wifi error.

Hope u understand what I mean.

Now, I flashed back to V9 #1009 kernel, which is still the best for me, problem free:p

@ doomlord

wow...wow...wow...u are the best man...! My phone successfully booted. But I found a strange problem. When I open camera then phone get restarted. Confirmed 5 times. But still I am happy that my phone can run now new UC kernels.

Edit :- Not able to play mp4 videos which was working flawlessly before flashing this kernel. Phone rebooted when try to play video.

Imp :- I apologise for wrong results. Everything works fine if I keep lowest freq to 300 mhz or higher. Below that above problems will occur.
[Samsung Galaxy SL i9003] RonnYap:
Using V11..still no find any bug yet..Recording tested 720x480, 1280x720 and camera work fine..On XXKPU . Setcpu min 120 max 1000mhz.
[Samsung Galaxy SL i9003] vishal24387:
for me also video camera take a long time to initialize. But at the end it just closes without recording (no fc). No problem in capturing photos. My configuration is as per my signature :)
[Samsung Galaxy SL i9003] DooMLoRD:
very interesting observation... so u dont have any issues related to camera/video play back if u keep min CPU freq >= 300Mhz?

good to hear that the kernel finally booted up on ur device :D
[Samsung Galaxy SL i9003] vishal24387:
Not exactly I can say like that. Below 300 mhz (say 120 mhz)everything seems to be messed. But above 300 mhz everything seems to be very good except camera.

Below 300 mhz ---

-vdo playback doesnt work

-camera crashes

-cant say about wifi (I dont use it :p)

-Dont have any other problems (I think)

Above 300 mhz ---

-everything works :)

-camera works in image mode

-camera crashes in video mode (take too much time for initialisation & then camera closes)
[Samsung Galaxy SL i9003] DooMLoRD:
@kernel devs

so guys i am searching how we can achieve kernel level CPU freq thresholding at bootup...

on the Qualcomm chips (MSM) its very easy:

https://github.com/DooMLoRD/android...mmit/6913a02249c650ba2f277e4c3a83815195798a00

https://github.com/DooMLoRD/Xperia-...mmit/a2d4efce0a7d18df3636793f7638483d97046736

we basically define the boot-up policy in msm_cpufreq_init function in the cpufreq driver...

we need to find similar location in the OMAP cpufreq driver to set the boot-up policy... once thats done the CPU will always boot at specified ranges and not jump to maximum possible CPU freq...
[Samsung Galaxy SL i9003] DooMLoRD:
try on fresh install of stock XXKPQ ROM and check if u get same issue "above 300 Mhz"

hi, really like your work , epic kernel but I have some issues with governor, almost all governor doesn't work correctly, only savagedzen and lionheart and smartassv2 maybe work good, others keep freq really high almost time,

more I will test with cpustat this night, because with xda bam kernel, smartass uses really a lot of frequency over 1000, like 5% , this kernel uses more than 40-50% :)
