[Samsung Galaxy SL i9003] DooMLoRD:
ya sure i will post a test kernel with 300Mhz...

the thing is i cant yet confirm if the overclock is actually taking effect... as i couldnt find a way to monitor current GPU clock..

these devices have dynamically scalling GPU cores... so even if we give high clocks they dont really take effect until GPU intesive operations are called for... sometimes the 2D & 3D rendering is done at diff clock speeds...

lets see...

yups its possible and very easy :)

but the thing is without voltage control there wont be a LOT of benefit from that...

once we get voltage control too then we can undeclock (to say 125Mhz) + undervolt (~850mV) and we can get good head room for overclock too... then the interface will truly be useful as we can get better battery life and higher stable overclock...

also since XDA_Bam is working on it i thought it would be best to concentrate on other aspects so in the same amount of time the three of us (me, Napstar & XDA_Bam) can work on more things...

read the post right above ur post...

when we get a OMAP compatible patch for it...

i have call recording patch implemented in my SEMC MSM8255/MSM7x30 kernel...

if u come across a patch for this device send the link to me and i will implement it

its not just app based... the kernel should provide the driver api for handling that...

This is how good UC v3 with smartassv2 and sio can be after battery calibration. I also use Green Power Premium. Additional tricks are 2G network, GPS and Autostarts to disable certain app triggers (SNS, Maps, Software Update). I have two gmail accounts and 1 email account, voice calls for half an hour, some SMS, and a little gaming during the time in the screenshots. Firmware is original DXKP9 without any modification, no deodex, theme or anything.

EDIT: Ouch, intended to post in Q&A thread but accidentally posted it here.
[Samsung Galaxy SL i9003] amit864:

hi i am out of station at the moment... i was trying to connect to my home PC via teamview but currently it isnt working so kernel cant be posted until i get back home/i am able to reconnect via teamview... i will be back home by saturday will surely post kernel then...

yups on 2G networks u will receive such battery life

SOME INFO ON BATTERY LIFE

when the device goes in 3G mode the wcdma radio drains battery rapidly compared to 2G gsm radio... thats why u get MUCH better battery life when using 2G (GSM) only...

its HIGHLY recommended that u calibrate battery (search on how to do battery calibration)...

as far as possible switch to 2G modes, only when u actually use the phone (screen ON) switch to 3G... there was some app to do this automatically i forgot its name...

[/URL] (MD5 Sum:c084022c2d9f5ac88e0dd4cb244cd166)

[Note]

We will merge final modifications related to GPU and governor tuning in our next release. Currently this release has UC-kernel v5 test3 related modifications.

Minmax and Hotplug governors are not modified because I did not find anything to tune in it specific to device.

DO NOT POST following types of reply:

Governor XXX is using ###.00MHz frequency most of the time

(Because this is governor's behavior and not my ;))

[For Developers]

For developers: My modifications are very generic, so anyone who wants to port these governors to any other device can use these patches directly without possible need of further tuning.

Sources are the same as given in first post of this thread.

Please test all mentioned governors and report if you face any problems
[Samsung Galaxy SL i9003] alex88510:
@napstar

can you provide a v6 kernel with v5 test6 modification?

v5 test6 quite stable and I think is better than v5 test3.

thanks for the hard work.
[Samsung Galaxy SL i9003] amit864:
I second that, V5-test6 is very stable. Also, can the OP change-log be updated. It is still at v4.

Lastly, what would be the test case for this kernel?
[Samsung Galaxy SL i9003] DooMLoRD:
hehe yes i will update the first post with this info...

BTW if u would have noticed we have marked v05 & v06 as TEST versions as we need user feedback...

v07 is already in the works and will contain v05-test6 + v06 changes + few more features :)
[Samsung Galaxy SL i9003] leongwenjun:
why remove minmax ，It is most smooth cpu governor :(
[Samsung Galaxy SL i9003] Napstar:
None of the available governors removed.

It's just that minmax and hotplug need no tweaking. And hence they are not TOUCHED (no modifications) and kept as it is in UC kernel v6.
[Samsung Galaxy SL i9003] leongwenjun:
oops,now flash it :P
[Samsung Galaxy SL i9003] alex88510:
this means that there will be no v6 kernel with v5 test6 modifications?

mine telling a little bit about the feature that will be adding to v7 kernel?

just a little bit curious:p
[Samsung Galaxy SL i9003] inciongd:
^

I think this is a test release that is why only test3 mods are there.

IIRC, v5-test6 had 2 hacks whereas v5-test3 only had the 275MHz GPU OC.

This is for finding any bugs with the governors I think. If bugs are found with this release, then it will be for sure related to the governors and not Hack1 and Hack2 in test6.

So this is more like V6-Test1 release not the actual V6. (Or maybe V5-Test7, 275MHz GPU + governor improvments)

@Doom/Napster

Looking forward to the release when governors and OCs are final and you move on to testing other stuff! :D

I read also a while back that in the future, the release path would be 1 Kernel with OCs and 1 Kernel with stock freqs. Is this sill the case?

Anyways, more power. I will be paying close attention to governors for this release, thanks!
[Samsung Galaxy SL i9003] HeathenMan:
I think test kernels should have stable basic kernel versions... a v6 test basic v5 test3 is not only confusing, you cant know if the bug is v5 test3 related or v6 ^^

Will try 6 soon as possible (now at v3 because of battery life)

edit:

v6 2th reboot stocking at "samsung" long time before starting (show pin etc.)

put phone off, starting again - now no sd card apps are installed? - this was fixed after unlocking a minute later, very laggy for a moment but apps are there again.

and it takes some time to get into shutdown menu (airplane mode,shutdown and so one) - with v03 this was very fast

im scaling savagedzen (as default) with this profiles:

[Samsung Galaxy SL i9003] rk7987:
@ inciongd

does your HTC like clock widget has 3D flip time change effect ??? And whats the APP ?
[Samsung Galaxy SL i9003] Napstar:
Before tuning, in most of the governors the default maximum frequency was set to around 1.5 to 1.8Ghz. And so with those settings our device used to stay at its highest possible frequency for most of the time, giving better performance. But now with these tuning now governors know their actual limits. And so you could feel the actual behavior of these governors. If you set yoyour governor to performance while booting, you wouldn't feel the lag.

Smartass governor is actually smartass. It dynamically controls the ramping speed and tries to maintain cpu frequency close to a mid range frequency. So balancing both performance and battery life simultaneously.

Off-topic mate.

[Samsung Galaxy SL i9003] ganeshbiyer:
You can put it in any folder. My folder structure is 3 levels deep. Its is not an issue. It even asks to select Internal or External Sd Card.

I have been downloading and installing all the UC Versions from my mobile since installing mobile odin. It is such an awesome and convenient piece of s/w.

So there should be some setup issue or the downloaded file is corrupted. Try re-downloading the kernel again.
[Samsung Galaxy SL i9003] alex88510:
Time for some feedback:

Recently I am playing Crystal Defender.

When I was using v5 test 6 kernel, I can play smoothly~

Now I flash v6 kernel, found that it is a little bit hard to deploy the army. When I touch the screen and hold to a type of army and then drag to the field, it easily drop(act like if I left my finger away from the screen).

Tested many times, still the same, previously don't have this problem.

the battery temp using v6 kernel is a little bit cooler than v5 test6 but just 1~2 degree Celsius difference.(v5 test6 : 41.0 / v6 : 39~40.0

Not sure whether is it just me that have this kind of problem.

Currently thinking of flashing back to v5 test6.
[Samsung Galaxy SL i9003] Annita:
Now I have v4. Is v6 a stable relase or also a beta release?

If I update/downgrade to another firmware or ROM, do I have to reflash the kernel?

Thanks.
[Samsung Galaxy SL i9003] amit864:
v6 is stable. As such you would not notice any substantial difference.
[Samsung Galaxy SL i9003] vishal24387:
no problem in downloaded kernel. Problem is in mobile odin. When I kept kernel in external sd then it failed to flash via odin but when i kept same kernel on internal sd then it flashed correctly. Its a small bug but need to be corrected.

Now back to topic...the kernel works superbly. I can feel change in smoothness of go launcher at smartassv2 & sio. Also temperature remains cool while charging. Dont know about graphics performance as I dont play hd games. Yes...battery life has definitely improved little bit due to optimised governers.

@ doomlord

i heared about ram swapping to increase ram virtually. Can it be possible in our phone? Because we actually get user ram as nearly 210 mb ram only even though we have huge 487 mb ram :(

And really thanx alot you & napster. You both are making our kernel superb. And i know that u will make this kernel much...much better with more features in future :)
[Samsung Galaxy SL i9003] DooMLoRD:
already answered abt ramzswap somewhere in this or the other thread...

short answer: no need of that for this device
[Samsung Galaxy SL i9003] HeathenMan:

it isnt stable :rolleyes:
[Samsung Galaxy SL i9003] DooMLoRD:
its called TEST cause we want users to TEST OUT THE FEATURES...

"unstable" versions will be marked as "ALPHA/BETA/UNSTABLE"
[Samsung Galaxy SL i9003] ganeshbiyer:
It is not.

FYI, I was flashing all these days from external SD card. Just to test, I flashed from internal sd card too. It flashed properly. I was on UC6 , flashed UC4. It shows UC4.

In short there is no bug in Mobile ODIN.

@Doomlord

I usually do not comment on any kernel. I don't think I have.

That only means:

1. I have had no issues with any kernel.

2. Most of the issues, non-issues are already getting posted.

Hello, I have feedback from governors in v6.

I seem to have gotten some audio skipping/lag for PowerAMP. Tried all anti lag settings maxed within the APP (max buffer/max audio priority) and still I get skipping from time to time. No problems before on Stock XXKPQ, UCv4 and UCv5-Test6. Just a minor annoyance, nothing major.

I tried:

smartass

smartassv2

smoothass

savagezen

minmax

conservative

all with VR, SIO and BFQ

Tried freezing background apps (tasker, alarm clock plus and Ti-sync) via Ti-Backup, still the same. Also tried disable SetCPU and use No-Frills CPU only, no effect.

If I use performance and lock the MHz in 600min/600max, 800min/800max or 1100min/1100max the skipping is gone. Maybe before PowerAMP triggers a higher clock when running? Maybe now it just stays on 300mhz when the screen is locked?

The biggest issue with this kernel is it takes a REALLY LONG WHILE to boot :/

it's a good kernel, but i've tried with the stock one and with this one, and regardless of the ROM i have, the boot time is increased substantially :)

can it be fixed?
[Samsung Galaxy SL i9003] mdarksoul:
Probably has something to do with the governor used when it was turned off
[Samsung Galaxy SL i9003] DooMLoRD:
the governors u enlisted function as following:

if the device is in screen off state then most of them throttle the cpu freq to lowest possible, to achieve max battery life...

previously the governors were not tweaked so were not functioning optimally... now they should start working as expected...

the kernel has lots of optimizations to reduce size and has tons of features... these things increase the bootup time as the kernel+ramdisk has to be decompressed on each bootup and the other features take little bit of time to start/kick in...

we will try increasing the bootup frequency but thats abt it...
[Samsung Galaxy SL i9003] Misledz:
The recent optimizations seem to be up to the expected level, it's been about a day and a half with v06 and vr and smartassv2 and so far, Ive been using LW like a *****, and it's been smooth sailing without any issues :O Except for the battery drain :D
[Samsung Galaxy SL i9003] voit:
small description - during Wi-Fi turned on I saw frequency changes from 300 to 1100. CPU load at this time wasn't above 20%. It didn't had dependency on governor type (even in powersave).

I have one question - How can I eliminate using 1100Mhz at all?
[Samsung Galaxy SL i9003] Napstar:
I have noticed that. Any of the governors tweaks will not have this kind of effect. I guess this is rom related. We will try if we could do something about it.
[Samsung Galaxy SL i9003] ggclanlord:
It id related to ROM.

If you set frequency manually, say min- max 300-300 using SetCPU, still it sometimes goes to 1000MHz sometimes, like when Wi-Fi is turned on.
[Samsung Galaxy SL i9003] fan-man:
Tell, please, is BusyBox in UC_KERNEL_v06? Or it is necessary to establish in addition BusyBox?
