Forgive me if I sound rude, but if I were in Doomlord or Napstar's shoes, no matter how good you mean, it would piss me off..

Team UC has repeated the fact over and over again, that they WILL work on ICS kernel once THEY decide the kernels for stock roms are good enough.. We all know that they are working on cpu voltage control (and other issues that exist on v13 plus usb otg) ... We should just let them concentrate on that..

Once they're done with stock kernels they're obviously going to shift their focus to ics and Team UC will do their best to get the aosp roms working, 2.3... or 3.0 kernels, its for them to decide...

Have patience guys, let's not try and sail on two ships at once coz it'll get us nowhere.. Cheers..
[Samsung Galaxy SL i9003] prince_venom:
im with u Abt Fuss. We donated him the Device in the name of ICS porting and after getting device he just Gone Away. We know he contributed to MIUI bt we also know 90% of work was done by JP alone. He could Contribute work with dhiru bt instead he took his own way and now gone.

Dhiru,napstar,doomlord,vurrut and Codeworkx done their job for the purpose for which we donated them the device. and they Rocks specially TEAM UC and Dhiru salute U Guys

Feedback

i have flashed v13 yesterday and observe the following:

- kernel is great with max 1300 MHZ for my device

- i faced random Reboots while on 1350 and 1380 MHZ

- faced FC and hangs on 1380 MHZ

- The wipe section of recovery seems buggy cause i dont find the "yes" button on confirmation screen

Overall Grt Kernel with Grt Efforts By Team UC ...

although i found v8 far more stable than any other version for my device :D

cheers :)
[Samsung Galaxy SL i9003] marshygeek:
Hello. Is UC kernel only available for XXKPQ roms? Is there no cf-root but OC up to 1.2 ghz but from this team UC? :)
[Samsung Galaxy SL i9003] rarap:
regarding "yes" button on confirmation screen,it is there.but since "no" button is too many,you need to push the on-screen "down" arrow before u can find it.i also thought it is a bug before
[Samsung Galaxy SL i9003] earldroid:
No. It is considered universal because its based in universal cf root :D. But if you flash it besides XXKPQ, you have to know that you shall be flashing it at your own risk.

[Samsung Galaxy SL i9003] Napstar:
I did not know that yesterday and today was so hot in this thread. :P

For last few days i was trying hard to get wifi error fixed, but was unsuccessful. if any developer here could help me out with porting wifi module sources (tiwlan_drv.ko is module and is compiled using android-device and not kernel sources), I will be really thankful. i succeeded in compiling them but could not get them to work.

Anyway, yesterday i had some office work and was also trying to get vdd sysfs working. rates why i didn't check this thread. and today i had returned back to my hometown, where there is no internet.

Well that explains my absence but today when i was almost done with vdd sysfs and was about to vinit those changes, sadly i did a reset of my git repo. :eek:

Luckily few of the files were open in an editor (meld), so now

i am trying to recover my changes.;)

hopefully if i could recover them, i will post a new kernel tonight.

and then will try to port kernel for ICS tonight itself, as i will be out of town and away from my development pc for next two days. :(

(Though I will be able to access internet from there and could check on updates. :))

So my request is to "please be patient" and "do not reply to this post" which will lead to further spamming.

Thanx for your support!

UC-Kernel v14 Released!

[ screenshot ]

[ features / changelog ]

DSP frequency corrected furthermore to fix problems with video playing, recording etc.

added vdd sysfs (v1401)

[ Note to change vdd levels ]

To check VDD table

cat /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels

To change voltage level of a CPU freq, let's say for 900Mhz change of voltage from 1000000 to 1050000

echo 900000 1050000 > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels

[ Problems ]

wifi error still exists. When you use wifi your device won't use 120 and 200MHz frequencies. You need to reboot for that. We are trying to fix that.

And we will be still working on USB_host and porting our kernel for ics but after few days ;)

[ download links ]

KINDLY DO NOT MIRROR OUR FILES

please test out both these kernels and post your feedback!
[Samsung Galaxy SL i9003] jan3586:
initial testing:

most problems in v13 solved.

new issue with front facing cam, it displays a shaking image of rear cam. after switching to it, the phone generally slows down. tested on both versions.

Q regarding wifi error: Can I prevent it by limiting the minimum freq. to 300 Mhz?

my setup:

vurrut rom v5, ics theme by vishal.

smartassv2 sio 1.2 ghz max 300 mhz min
[Samsung Galaxy SL i9003] dhiru1602:
Spent 2 months on getting that to work. No luck.
[Samsung Galaxy SL i9003] Napstar:
I thought the wifi error was with having unable to use freq below 300mhz after switching on wifi. If your min CPU freq is 300 then you have no problems.
[Samsung Galaxy SL i9003] Adi_Pat:
I am ready to help. Is this for 3.0.x Kernel?

---------- Post added at 10:40 PM ---------- Previous post was at 10:36 PM ----------

Hello Napstar,

I needed some help with 2 patches.

1) The one in which boot-up speed is restricted to a certain speed. Since many ppl had problems with Kernel to boot with freq overclocked to above 1.2Ghz.

2) The DSP Fixes, since some ppl have video issues.

Thnx. And my sources are here ->https://github.com/AdiPat/i9103_Kernel
[Samsung Galaxy SL i9003] shriom_manerker:
btw the sources are available by samsung ? m asking cus as far as i remember the source was always incomplete
[Samsung Galaxy SL i9003] XDA_Bam:
I second that. It would be great if you could bring your GitHub up to date so we can have a look at your patches. I would appreciate it and am eager to apply one or two of them myself :)

Same here
[Samsung Galaxy SL i9003] |DM|:
i'm not sure because for the moment I can't flash it, anyway you must search on market app like antutu cpu master, or set cpu or same to set voltages

for example, on cpu master, there is a tab to manage voltages.
[Samsung Galaxy SL i9003] concepcionjfq:
Hello Guys, i need help, i want to go back to stock xxkpq or xxkpu because my phone keeps on restarting/auto-power off and it cant last for 5hrs not using it, but i still want my phone rooted and has cmw, sp what kernel you can suggest? also when i install a crom or ics themes same problem happens, and besides i need skype/video call to work, thanks in advance,
[Samsung Galaxy SL i9003] ivAnash:
Team UC V9 was the last I used with no issues whatsoever, on stock xxkpq.. Try it..
[Samsung Galaxy SL i9003] velve.ffff:
Ehm, can u napstar when u have time ( or doomlord but i think the v14 source is on napstar pc ) push and update github repo?

i'm really curious about this:

[ v12 onwards ] implemented slightly better CPU freq thresholding at boot-up - this will reduce the time the CPU is at max frequency... this is still not implemented at kernel level but we are working on it

thanks a lot

EDIT: For voltage sysfs, if it's respect standard you can use Voltage Control app ^^
[Samsung Galaxy SL i9003] hpog:
Hi. Installed v14. Had about 3 bootloops initially but then it settled down later on. I tried HD vid recording on min300max1380 freq & had no problems. Hvnt testd forward camera & still camera yet..

I had forced reboot though when i played with SAS3 zombie assault at min 400 max 1380, performance governor. Also ate up 40% of my battery in about 15mins & raised temp to 42 deg.. :D But that's expected. With other frequencies higher than 1000 it was ok. I experienced some lagging in the game sometimes, but maybe its coz of my other programs.. Will test on other games soon..

Also had SOD aftr a while using min120mhz max1000mhz with smartassv2 gov.

Im on xxkpq, tarunagg ics theme, uv kernel v14. Flashed v14 via mobile odin.

I hop this mks sense. Thanks devs.
[Samsung Galaxy SL i9003] sirilpta:
Using v14 UC kernal on ddkp3...

No problem with video recording and playback.

But sometimes when i swap to front cam it shows a distorted image of back cam, but after a snap it becomes ready.

The CPU doesnt enters 120MHz & 200MHz.... Tried with 120-1000MHz Lionheart but it stays at 300MHz as minimum..

[Samsung Galaxy SL i9003] vishal24387:
in set cpu keep ur max freq whatever u want & keep min freq 120 mhz.

Then set screen off profile in set cpu with 120 mhz max & min freq. Then activate/apply this profile. With help of this my phone easily goes upto 120 mhz when screen goes off.
[Samsung Galaxy SL i9003] sirilpta:
Tried as you said but no luck this time... I think its bcoz of ddkp3.

[Samsung Galaxy SL i9003] alex88510:
Another question on the vdd sysfs.

When we change it, will it be reset after reboot?

What I'm worrying is when we set a voltage value which the phone cannot handle, it will hang or anything bad happen right?

so if the value is still won't reset even after reboot, it will be a bad disaster to our phone.

Another question to confirm about the wifi error.

The wifi error problem will be triggered by what?

Saw some post earlier, it said when you keep min 300mhz, the wifi error won't happen.

How about max 1300mhz or above?

Because I faced wifi error problem before in previous version of kernel with min 300mhz max 1250mhz.
[Samsung Galaxy SL i9003] Napstar:
Sources are on my PC but its not with me currently, as I had mentioned before.

Having a lot of traveling since last week.

Anyways I will update them as soon as I return back.
[Samsung Galaxy SL i9003] Napstar:
Vdd table will reset after reboot only if you have not used any app which has "set on boot" option.

If you are varying VDD using terminal emulator or through adb it will reset.

I can't comment on wifi as I am using cm9 right now
[Samsung Galaxy SL i9003] Napstar:
I suggest using adb shell or terminal emulator and follow these instructions:

[ Note to change vdd levels ]

To check VDD table

cat /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels

To change voltage level of a CPU freq, let's say for 900Mhz change of voltage from 1000000 to 1050000

echo 900000 1050000 > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels

I had problems using app though I have used standard SVS format.
[Samsung Galaxy SL i9003] joelmonty:
Im using the latest v14 version without the vdd thing,i have no issues with wifi,with the stock or overclocked frequencies not sure about underclocking.
[Samsung Galaxy SL i9003] vishal24387:
I know its a very silly question but still I want to ask u that whats the purpose of changing voltage level of any frequency?? Say for example we change frequency to minimum to save save battery or increase frequency to improve the smoothness of phone functions.
[Samsung Galaxy SL i9003] Taraen:
Lowering the frequency to save battery means less performance, but it you undervolt your cpu it will save battery but have the same performance. Of course that alone won't do very much, but if you lower the voltages for every frequency to a stable minimum and cut off your maximum cpu freqency you can save more power and that all the time.
[Samsung Galaxy SL i9003] chongns:
simple word, lower voltage drain with overclock.
[Samsung Galaxy SL i9003] Adi_Pat:
Thanks, I have a suggestion, Don't you think too many Governers are simple bloating the kernel?
[Samsung Galaxy SL i9003] velve.ffff:
Yes, but it's not influence at all, governor are 100-200kb sized each, nothing to hard, i think he include a lot governor because everyone has a favourite governor ^^ :)

my kernel ( wip only on github and not released for now ) , include only high personalized and rewrited for our device lulzactiveV2 and conservative governor tuned for battery from kernel 3.0 ^^

if dhiru lower its voltage, the kernel is more unstable ^^

I tested latest version UC-Kernel v14, cwm cannot restore backup (task android secure file), all before task restore succ..

I revert back to V9 (3009 without full touch) and restore backup work fine....
[Samsung Galaxy SL i9003] chongns:
not really, in my understanding, stablility, depend on the HW.

if you feeding enough power to the HW, it will be stable, once HW stable, SW also stable(provided the SW is atually bugfree)

however, in stock kernel, they set the "enough" value at the standard "safe value",

which is more than enough. so, some phone having over heat even on stock.

so, in the perfection value, you phone will be stable and cool. therefore, for the usage of UV, is to save battery power so can getting long up time but without sacrified the stablity of the phone.but every HW may having different break point, so that why it need to fine tune
[Samsung Galaxy SL i9003] -Cronos-:
Of course it changes from phone to phone, but in in general higher voltages (as in closer to the stock value) provide better stability at the expense of battery

[Samsung Galaxy SL i9003] velve.ffff:
of course, there re a limit and a perfect value, hw may having different voltage limit support, like overclock, but example:

Found an app in Play called Voltage Control. Can we use this safely on v1401? Cant find voltage regulation on my setcpu..
[Samsung Galaxy SL i9003] vishal24387:
Got it. I set screen off profile in set cpu as max & min freq should be 120 mhz when screen is off. I think phone is not able to react quickly when we wake up it by power key or by call at lower freq.

Hello guys, First of all a big thanks for all your hard work. :)

I've been using your awesome kernel for quiet sometime now but this is when I am joining xda-developers so here goes my first feedback :D

V14 - almost every issue in v13 solved including wifi (except for the device not going into lower frequencies issue), video playback, camera, etc.

The 1350 & 1380 frequencies are highly unstable with a lot of lag and crashes. The weird thing is that when I put the max frequency at 1350 or 1380 MHz setcpu shows my frequency going up to 2700+ MHz :eek:

And I can't change any voltages, voltage control doesn't recognize vdd so no voltage tab, same with setcpu and others except antutu CPU master but still can't change voltages. I also tried sending the "commands" but the phone restarts immediately eachtime with no result.

I am using KPU firmware.
[Samsung Galaxy SL i9003] velve.ffff:
I know, in the past i used model: MSM7230 of Snapdragon S2 in my acer device, but this is another device, only imho, i'm not fan of overclocking , but imho if overclock causes only problem ( like crash , reboots or others ), i agree little overclocking, like 1200 Mhz, this will make phone flying without any type of bug or problem, i'm not understand what's the sense of 1300+ overclocking ^^

=) i think there are more speed by optimizing the ROM and not extreming overclocking ^^

thanks anyway ^^
[Samsung Galaxy SL i9003] Gondya bhau:
regarding lag while playing high graphic games,

i think we would get more benefit if we could get a 100Mhz boost in the gpu(which worked/stable) rather than going for 1300-1400Mhz in cpu.....

but alas, no one has managed that yet :(
[Samsung Galaxy SL i9003] shriom_manerker:
forget gpu overclock ! it doesnt work on our platform yet ! once we get kernel 3.0 then it might be possible not right now
[Samsung Galaxy SL i9003] Gondya bhau:
i dont expect it from the current kernel.....else it would have happened by now...

The video recording bug still exists.. A few seconds into recording it hangs and then 'recording failed ' notification..

Even after exiting the video recorder , the phone lags bigtime and gets normal only after reboot... Also the cpu frequency had touched 1.3ghz when max was set at 1ghz..

UC v1401, xxkpq, lionheart, sio

Max 1ghz, min 120mhz
[Samsung Galaxy SL i9003] Napstar:
I will check that out..

What voltage value did you set and for what frequency?

Try and keep lower cpu frequency while recording. At 1GHz as max frequency, it should not create problem with camera.

[Samsung Galaxy SL i9003] earldroid:
But most people said battery calibration is a myth
[Samsung Galaxy SL i9003] vishal24387:
i dont think so...when u will do battery calibration u will come to know that ur battery will not show suddenly too much low battery after reboot.
[Samsung Galaxy SL i9003] alex88510:
Battery calibration will definitely help.

But recently found that my phone battery is easily out of calibration.

When I reboot the phone one time, I need to recalibrate again as it show very low %.

I'm sorry but I didn't quite get what u meant. Keep the min freq at 120mhz and max at 1ghz.. Is that correct??

I have not yet played with the voltages.. Just to let you know, the front camera is really choppy.
[Samsung Galaxy SL i9003] earldroid:
Ok will try calibrating my battery. But which battery calibration app really works? Theres so many apps in market.
[Samsung Galaxy SL i9003] ivAnash:
All of them work.. Try doin it manually..

1. Charge battery to 100%. Delete batterystats.bin from data/system using root explorer or similar app..

2. Drain your battery until the phone switches off.

3. Again charge it to 100%. Battery calibrated..

Make sure you do not charge or reboot in between the draining part... And also charge continuously to 100% the 2 nd time..
[Samsung Galaxy SL i9003] ggclanlord:
Even the step to delete the batterystats file isn't needed.

Just a couple of cycles of full charge and discharge does the trick.
