I know that as I have some limited kernel knowledge myself, saving space in the ramdisk was my original goal in asking. And I can be the person to test... if you need someone.

EDIT: Another thing, I don't see the use for NFS and CIFS much as ppl can use thing like File Expert with Wifi or Bluetooth to transfer files just fine. Disabling them might save you some space for later. As for what have been implemented from the change with NFS I think you can create share as you have the kernel space server implementation there, for CIFS you would need Samba server to create share though, and CIFS in the kernel is just a client implementation.

UC-Kernel v02 [XXKPQ]

[Samsung Galaxy SL i9003] DooMLoRD:
everyones requirement is different... we try our best to cater to everyones needs... i think its best to have these options enabled in kernel... i have anyways got the final kernel (zImage + ramdisk) to be reduced in size by around 20%... even with all these things enabled in kernel the final kernel size (.tar) is just 6.47MB which is even smaller than the existing Stock+CF-Root kernels u guys already had here...

@ doomlord

our community dont know much about new file systemes. We know only ext4. Can u tell us that for good performance which file system will be good to use as per ur experience?
[Samsung Galaxy SL i9003] deepanshu sharma:
downloading the new kernel.
[Samsung Galaxy SL i9003] sakindia123:
i read somehwere that jfs performs better for galaxy s than ext4
[Samsung Galaxy SL i9003] DooMLoRD:
if u do not wht it is exactly then u probably wont need it... this kernel is ment to provide support to modders and give them the ability to use these filesystems for their mods...

and again:
[Samsung Galaxy SL i9003] sakindia123:
sorry to ask again...but how do i "actually" change to other fs?use some kind of script,like we had for ext4?
[Samsung Galaxy SL i9003] DooMLoRD:
i wouldnt advise changing main systems fs... but u can play around with a small partition on sdcard... as for how to do it search... "parted" binary is there in the ramdisk... i think one can use it to partition...

I HIGHLY RECOMMEND THAT U DO NOT MODIFY UR SYSTEM/INTERNAL SDCARD PARTITIONS UNLESS U KNOW WHT U ARE DOING AND KNOW HOW TO REVERT BACK

REMEMBER CREATING NEW PARTITIONS WILL CHANGE UR PARTITION TABLE SO EXISTING DATA ON THAT SDCARD WILL BE WIPED

if someone plans to change system/internal sdcard partition FS then remember that the ramdisk will also need to be updated to support mounting of that FS (fstab file), even for recovery...
[Samsung Galaxy SL i9003] DooMLoRD:
also i have personally used mostly NAND devices where the YAFFS filesystem is the standard and pretty fast... so for eMMCs (the stuff inside SGS-SCL) i dont really know which is the best performance wise...
[Samsung Galaxy SL i9003] kancilpintar:
Guys, i know that we are all very excited about finally having a kernel developer for our phone, but as per doomlord's request, we need to start having a thread of FAQ about kernel development to reduce non bug-related post in this thread. Some senior members should take the responsibility (as I have a very limited knowledge and time).

Sorry for my off-topic post, I'll edit this when some action have been taken :)

if there are some genuine kernel related issues/bugs then divert the questions to this thread...
[Samsung Galaxy SL i9003] vishal24387:
yes its perfectly working with kpq. I cant test FS because dont have knowledge how to convert to new FS & how to revert back to stock. Other than that 2g, 3g, wifi, gps, performance, battery drain, touch response everything is working perfectly.

Its sad that we have only 8 mb kernel limit otherwise doomlord would have added so many stuffs to it.
[Samsung Galaxy SL i9003] sakindia123:
thank u very much much doomlord.....i've pmed some devs;noone replies

u do!

i studied your sources,they are quite self-explanatory

will help me or someone else if they buy a phone w/o any dev support(like i9003 was,once)

@Doomlord:

Are we still using Ext4 from the cf-root?

As I see in android_latona_r08_eng_defconfig

CONFIG_EXT3_FS=y

# CONFIG_EXT4_FS is not set

So when I compile the kernel

ext4 sources

are not compiled in

fs

folder.

Is that right?:confused:

Am I using the correct git?
[Samsung Galaxy SL i9003] amit864:
flashed successfully over kpq.

Glitches so far:

1. the phone did reboot on turning on wifi. After that reboot, the wifi started fine.

2. there is a hiss in the headphones when I turn-on or turn-off wifi.

Is there a way i can get logs for these events?

Hi Doom,

Its very hopefully if you make for miui/cm7 kernel too. Because in my test your kernel #3009 more stable then other kernel.
[Samsung Galaxy SL i9003] ooikaisheng529:
ITS ENOUGH.ANYMORE REQUEST FOR AOSP KERNEL WOULD BE GRANTED A BAN.I WOULD CONTACT THE MODS FOR KEEPING AN EYE HERE.:mad:

Hi Dude,

Why you so mad for it? I didnt push to MODS to do it for me. I just in hope and you can or any one can ignore it.

Do I wrong to hope for the best for our device?
[Samsung Galaxy SL i9003] vishal24387:
doomlord already said that he dont want requests anymore regarding miui or cm7 kernel. He said that 1st he want to make stock kernel as best as possible with all capable feature. And after that he will start to work on miui, cm7 kernel. Hope so u understand & I expect some patience from now onwards :)

Thank you

Connection Between Battery Life and Mobile Signal

I noticed something about battery life and mobile provider signal. If you are in a place where mobile signal is always strong, you get a lot more battery life from your phone.

I normally live in the Philippines, but in a recent business trip to Singapore my battery suddenly lasts longer. It seems to be because phone signal is always strong in SG, at least in the area I am in. Here are screenshots.

In PH, signal drops out sometimes.

Roaming in SG, signal always green. Notice the sudden battery drop when there is a yellow signal. Probably while I was riding the train. Its even stronger than the battery drop when using wifi!

Maybe our phones take so much battery when trying to detect a mobile network that is not there.

Just sharing, I am on V09.
[Samsung Galaxy SL i9003] Erahgon:
That's a really good observation! Infact, I always manually detect my carrier from the menu and I can confirm that I consistently have gotten better battery life doing so (rater than keeping it on automatic). The only downside is that when you're roaming, you need to manually go in and search for carriers.
[Samsung Galaxy SL i9003] alex88510:
Basically, when the signal is poor, your phone will create a more powerful electrical waves in order to capture the signal. Thus this end up using more battery.

If you know you are in a poor signal area and you are not using the phone for calling/answering phone, put it in airplane mode. It can help save battery.
[Samsung Galaxy SL i9003] DooMLoRD:
yes this is a very well known thing...

even selecting "automatic time settings" sometimes causes HIGH battery drain...

LOTS of things contribute to battery life...

2G/3G connection type

data enabled/disable

signal strength

automatic/manual n/w selection

wifi/bt/gps

finally, usage of that person
[Samsung Galaxy SL i9003] longfeng:
It is a known fact.

You can use "No Signal Alert Pro" to record the place and time for bad signal. Then you can use profile changer to go on air-plane mode during these times.

It makes sense since you have no signal anyway and the phone is fanatically wasting battery trying to get signal in a dead zone. From a report I read: When a phone is desperate for signal, it will behave like a microwave and radiation is very strong.
[Samsung Galaxy SL i9003] oudai:
can i use this kernel on a i9003jxkp3 it's an arabic 2.3.6
[Samsung Galaxy SL i9003] Napstar:
Although we can not guarantee with other ROMs except XXKPQ. But you can try and report here.

Make sure that you have backup of your current device. (NAND + BOOT image)
[Samsung Galaxy SL i9003] juanmaper:
This kernel work on KPH ! is there an option so the phone never go to deep sleep? I dont care about battery saving.

Thanks
[Samsung Galaxy SL i9003] vishal24387:
can u add extra OC & UC beans like in vurrut kernel???
[Samsung Galaxy SL i9003] xarolx:
sorry for off topic.

You may try this app , Wake Lock - PowerManager , free from market.

*I never use it, but from desc & comment ..given positive feedback. :)
[Samsung Galaxy SL i9003] longfeng:
I am not sure if I am the only one facing this issue @1.3GHz.

After around 12-20 hrs, WIFI will somehow unable to connect and sometime reboot randomly.

Or am I the isolated case?
[Samsung Galaxy SL i9003] juanmaper:
Thats the app that wake the phone every 5 minutes? Its useless, if you are chating via whatsapp or any chat and you lock your phone you will have to wait 5 min till it notify a new chat?
[Samsung Galaxy SL i9003] kikejulia:
You are talking about "wake my android pro".

Wake lock - power management lets you acquire wakelocks, meaning it will keep your phone constantly awake. It will never go to deep sleep, but your battery life will be very affected.
[Samsung Galaxy SL i9003] Napstar:
Do you mean WIFI usage for continuous span of 12-20hrs?

May be it depends on your usage.

I am on v3009, never faced a random reboot.
[Samsung Galaxy SL i9003] longfeng:
I happen to see vurrut ROM also has the same problem. I am using stock KPQ and uc v9 oc. need advice.
[Samsung Galaxy SL i9003] juanmaper:
Thanks for explain. I am using this app, but it really drains battery. So theres no solution for the notification bug? In froyo this happens?
[Samsung Galaxy SL i9003] shriom_manerker:
@napster-This kernel works fine on the latest rom ddkp3 :) which has improvements in battery efficiency,speed and better memory management :) give it a try if u'd like :) u can edit the op saying it supports ddkp3 (to avoid noob posts asking for this) ! seems like its gonna replace xxkpq :D
[Samsung Galaxy SL i9003] kikejulia:
As far as I know, froyo did not have the push notification bug. It has been introduced in gingerbread, and there is no solution so far, but keeping your phone awake, which will drain your battery.

[Samsung Galaxy SL i9003] supergaijin:
there has been explanation on this before, the newer versions of cwm have this error, but it's not an error. it's simply a bit of "uncleaned" code that's no longer necessary. your cwm is working properly. now clean up your first post and remove that quote! ;)
[Samsung Galaxy SL i9003] ganeshbiyer:
This was because the earlier cwm used to backup internal SD card too. But lately stopped doing so. Sd-ext refers to internal SD card. No problem with cwm though. Just ignore the error.
[Samsung Galaxy SL i9003] Napstar:
I faced this problem day before yesterday only. And this will be fixed in next release.

i can understand someone requesting ICS kernel (3.0), but why for 2.2? Any particular reasons?
[Samsung Galaxy SL i9003] juan272:
I'm thinking about going back to version 2.2. - The reason is the problem with notifications. I think when you get a smartphone with these characteristics, is looking to be connected at all times and in contact with everyone. Just for that ;)

Note that each time there is a new version for the device, the first or second post asks if the notifications problem was solved.

UC Kernel v09 (test kernels) with FULL TOUCH RECOVERY released!

[ Video ]

[ changelog ]

Support for full touch recovery based on CWM

[ NOTE ]

currently recovery does not show options for backup to or restore from internal sdcard though it deals with internal sdcard only.

if you do not want to take backup of sd-ext then use advanced backup.

We will release a final version soon with a single cpu table settings etc.

[Samsung Galaxy SL i9003] itsme12345:
Napstar, First thing really appreciate your work coz i just asked you about sd-ext and its implemented in you latest release. second thing i asked less and you gave more by adding the new graphical interface. really great job.

Instead of rainbow clourful theame, if it was like ics graphical interface (background) then graphical would look more excited.. when we press tab it should have blue clolur tab press (just a though for not confusion as now when we press the tab becomes red and in the colourfull them its just not giving full concetratioon what tab is pressed)

Thankyou for giving the /sd-ext (i am not sure if the /sd-ext is functioning correctly, becuse /sd-ext is limited only to recovery, when we boot up in the phone /sd-ext is not found. reason could be in recovery.fstab/recovery.rc there is no update of mkdir /sd-ext that could be reason its not showing when phone is booted. also /sd-ext mount option should be ext4/ext3/ext2 where as in recovery.fstab is shows vfat) sorry if my understanding is worng.. when i checked the parted command the /dev/block/mmcblock0p1 is pointing to internal sd where as it should point to the external sd partation were we creat a seperate partation, rest all work pretty cool..

sorry if any comments or typos... also last request it would be better option if there would be option of converting the newly created sd partation to convert from ext2-ext3 and ext3-ext4. (not a requirement just if it is possible then only coz i am removing my sd card and using my spice mi350n home phone to convert to ext2-ext3-ext4. thanQ all you guys...

Dunno if you are still looking for feedbacks...

I've been using your kernel, 1009 version, for a week and a half now, and I had no issues with it at all...

Rom Specifications: XXKPQ - Poseidon's rom

Frequency: 1200 Ghz max - 300 Ghz min / Lionheart / cfq

Battery lasts around a day with wifi disabled (3G on), using whatsapp and the web browser frequently, not playing games though...

Since it's my first over clocked kernel, I must say that it is a GREAT improvement, even though I did not choose the highest version. Apps run smoothly and even the launcher full of different widgets is as smooth as silk ;)

The new recovery is great! Its appearance is amazing!

Hope you find it useful ;) cheers!!
