Rc_3.3_oc_test

Booting ArcKnight Kernel_RC_3.3_OC_TEST right now... Booted up fine and nothing to report right now. Going to fully charge battery, then start using (=testing) it. Was using Sirkays kernel before with Smartass V2 governor and SIO. Will be interested how ArcKnight_II gov works... It felt pretty snappy after quick testrun.

Clean Install?? Just post the feedback as I requested it please :)
[Xperia Arc Android Development] arpith.fbi:
guys listen...here is how to test whether battery drain is there or not.

install battery monitor widget,batterystats..

turn off the wifi,bluetooth,internet and then leave it for atleast 3 hrs...

dont freaking touch the phone..

after 3 hrs..open the battery montior and see how much time does it took to drop 1%.and report us back here

i cannot test right now coz i m out..will report back once i flash the kernel
[Xperia Arc Android Development] borjacamb:
sorry, i just edited post.

Clean install? how i can do a clean install in a kernel? I only know do clean install with roms, not with kernels, can u explain plx?
[Xperia Arc Android Development] arpith.fbi:
tats wat he meant dude..he meant clean installing ROM
[Xperia Arc Android Development] borjacamb:
ohh, them yes, was a clean install, but now i just change kernel, not rom. i was with trinity kernel and just change to this.
[Xperia Arc Android Development] arpith.fbi:
clean install in this context means flashing the kernel..then clearing all data cache etc..then installing the rom..
[Xperia Arc Android Development] borjacamb:
Ok, idk that when i install a new kernel i should do a clean install of the rom, thanks a lot for ur help, i will do it now

Generally smooth and nice. 2 problems that I found. 1 - after changing governor to smartass v2, phone was so laggy that I had to wait a minute to see a change on screen so I removed battery and after booting it was ok till changing to other governor and again laggy as hell. Secend governor was intelliondemand I think. Agint removed battery and booted fine, then quickly I've changed governor to arcnight II and now it's fine.

2 - I think that waking up device from lock screen is way to long. I mean it's not so bad but it takes visible more time than in previous kernel. It does not matter which governor i'm using.

That's all for now. And NO I did not make a clean install yet. Gonna do this right now and then I will report back if anything changed.
[Xperia Arc Android Development] XDAarc2011:
Hey all,

i did a boot up screen for this great kernel.

Hope you like it
[Xperia Arc Android Development] jimbo77:
Thanks for the FeedBack! The issue with Intellidemand and SmartassV2 is that those governors also need to be updated everytime the cpu source change. I've taken the time to optimize my ArcKnight_II governor but not those two. Anyways I'm glad (Aside from the lockScreen issue) you find it kinda stable...

After clean install there is still issue with waking up device. Phone is just sleeping too deep:D But I do not have this problem from post above:

"2). notification sound lags when the screen is off and message is received"

Notification sound is working perfectly. I'm using JJ's Hybrid ROM 3.1.

Some SS from antutu:

Test without clean install. No OC :

Test without clean install. OC -> 1.6ghz, sd boost (2048 cache):

Test after clean install. OC -> 1.6 GHZ, sd boost (2048 cache):

Phone is extreamly responsive and smooth. I can surely say that this is the best kernel for ICS so far. Of course beside issue with waking up device. Also can't say anything about battery drain. Too much using and playing with phone to say someting about it. I'm gonna report back about battery tomorrow!
[Xperia Arc Android Development] Okluzhion:
3h 26m, screen on for around 1 minute total, down to 98%. I usually have imo and clipper apps on, but now I don't. I don't have problems with waking up phone, no delays.

I've tried ondemand governor and nothing changed. Maybe the reason is that I'm on OC kernel and subriel is on stock one.

And after unplugging phone from computer, it was awake until reboot. I've read that this is android os issue and we need to reboot device always after charging but it was the first time that this happend to me. The good thing here is that even when phone was awake it did not drain battery so much :P and screen lighted up immediately but I thing it's normal when phone is awake.

Guys!

More than 175 downloads and only a few ones has given me feedback???

I need more feedback to improve the kernel Experience!!

So so far i think both versions (Stock and OC) are working fine and battery life indeed improved.

ArcKnight_II Governor seems to be working really good isn't it?

The only Known bug (if it can be called that way because i think it is related to the way the phone is "Sleeping"... The deep sleep changes i made are working pretty good it seems haha) is the Wake Up Screen that takes a little bit more than Stock kernel right?

Thanks for testing guys and keep that feedback comming please!!!

[Xperia Arc Android Development] ALi___:
jimbo77, your kernel has support for ext-4 filesystem, how do i convert the system partition to ext-4?
[Xperia Arc Android Development] jimbo77:
I've seen you posting the very same question in every kernel you have tried. I'll try to investigate on the SGS forums. I also had one but please try to investigate on you own too...

*********************

Doing some quick investigation found out this zip file that will convert your partitions to Ext4..

http://dinc.does-it.net/EXT4_Mods/Convert2Ext4_normal_data.v1.0.zip

Refer to this Thread for more info on that:

http://xdaforums.com/showthread.php?t=1315372&page=42

******

WARNING:

Im not responsible for any PROBLEM/ISSUE your phone may get you can try that procedure under your own risk.

Besides I don't think it will work with any Custom Kernel at the moment since the recovery.fstab table in the Ramdisk is hardcoded for YAFFS2 FS in all partitions, so a new ramdisk will have to be created in order to use /system or /data as Ext4. I'll try to create a new one but that will be probably during next week..

This is the actual recovery.fstab:

[Xperia Arc Android Development] fahad123:
jimbo your kernel is real good and yeah it is the only known bug to me and the most of those who tried it... because the phone wakes up late and because of this sleeping thingy the sms notification or any notification sound lags when the screen is off! other than this is the best ics kernel!! :)
[Xperia Arc Android Development] jonxz:
I would love to give some feedback, but it is so smooth and I don't have any issue yet. Would love to let it go through a few recharge cycles first. But it really doing a great job saving battery, awesome!
[Xperia Arc Android Development] jimbo77:
Which version are you running on? Stock Based or OC? Also what network are you on 2G or 3G?

Thanks for testing! :D
[Xperia Arc Android Development] ALi___:
correct. i asked you and the trinity kernel guy. because both kernels say 'support for all filesystems'. so i'm justified in asking for a conversion method as the threads fail to address the issue.

i did investigate, but to no avail, hence i resorted to asking from the developers themselves. there couldn't be a more reliable source.

usually, conversion option is embedded in the recovery.

i appreciate your reply. though unsure whether i'll be able to follow the guide. but thanks anyway.
[Xperia Arc Android Development] jimbo77:
Well remember that SGS and Xperia Arc are two different phones and so the needs. Did you ever tried CM7 on the SGS?

It was fast as hell and way faster than the Stock Samsung ROMS and it was because when you were flashing CM7 it will auto convert system partition to YAFFS2 and data partition to Ext4 so i think the gain in performance is not going to be that much since we are already running on YAFFS2 FS on System.

The conversion was embedded on the Recoveries (Just like Mialwe's Midnight Kernel) due to Samsung was using RFS (The slowest FS Ever) so this lagfixes were needed to have a faster system and better experience.

You can try oppening the zip file and deleting the lines where it formats /system and /cache and let it only format /data ot Ext4.

Try and if the phone can't boot after the conversion just flash a Stock ICS image through flashtool and you'll be fine...

Of course do a backup first and after flashing the stock ftf just restore.

Don't take it the wrong way but it might not get that much attention since not everyone needs a lagfix here on the Arc section.

Test it and if it doesn't work I'll to make a special ramdisk with Ext4 on System and Data for you ok?

[Xperia Arc Android Development] landis90:
Thanks for your work but i'm having issue with Wifi, not able to turn on.

I come from arconium 2.4 and Doomkernel. Do a factory reset with full wipe, flashed your kernel (3.1), flashed Arconium 4, flashed you Wifi kernel modules (3.1) and it doesn't work. I tried to reflash the rom and modules again but nothing happens.

Any suggestions?

Many Thanks
[Xperia Arc Android Development] ALi___:
so, the reason arc developers aren't inclined towards ext-4 is that the difference between yaffs2 and ext-4 isn't that drastic.

again, i appreciate your thorough response. i get a clearer picture now.

but i still see lag at most occasions, so i thought ext-4 is what it might needs.

i remember converting to ext-4 would double the quadrant score, and it was reflected by the smooth sailing of the ROM. i find arc superior in terms of hardware but the ROMS available aren't upto the mark.

i'll try v3.3..

I/O Scheduler: sio

Network: dont know :( - i think 3G

ROM: Arconium ICS 4.0

What i experienced in 2 days now:

Pro:

+ nice scrolling, no more "hops" while scrolling

+ nearly no lags in gallery or long app lists

+ possibility of setting cpu speed and so on

Con:

- two sudden force closes until now: xda app (with ArcKnightII), root explorer (with SmartAss2)

- still based on linux kernel 2.6 ;)

- so called battery drain seems to be a little more than with stock, but 3% in 7 hours with no data connection over night is ok. when phone is in usage it seems like the battery is getting empty a bit faster than normal. if i don't use it a lot i can use it 2 days.

- left and right scrolling is too responsive for me: in photos and weather app when scrolling down it behaves like scrolling sideways (so the photo or my location changes to another one)

- when opening the "simple calendar widget" preferences i can only see the headline with the rest of the screen being black. when tapping on the black i can shortly see the menu and it leads me into the blind-tapped menu.

- In the app drawer the last maybe 2 or 3 lines are cut off

- forgot to mention:

I hope my findings are all kernel related... :)

I found it's hard to use up the battery to complete a recharge cycle LOL. ArcKnight_II is working very good, can't really see the differences between ArcKnight_II and Smartass2.

Smoother than the previous version (Arconium MIUI is the smoothest ROM I've tried, personally highly recommended), I had a slight delay when turning on screen when using RC3 now it's gone. No FC so far.

I usually use my phone for Whatsapp, newspaper via browser, Friendcaster (official Facebook app drains battery for no reason and slow), and of course talk on the phone.

Around 2% per hour when sleep even with WiFi on, I think this is pretty good.

I think the only thing I can complaint is... when the phone is in deep sleep and I have a call, it takes a while before i am able to pick up the call, but it's not too bad and is acceptable. (I suspect this is due to CPU is at lowest frequency when in deep sleep and phone and dialer require high CPU to launch)

My usage is heavier on weekdays then weekends, so I will update later with heavier usages in one or two days.

Battery life is good but I wouldn't say it's like in stock kernel. I can't get any lower than 1% per hour in stand by while in stock kernel it even can be 0.3 % per hour in deep sleep. So for me we got 3 things to fix:

1. USB-OTG support (gonna be in next stable release as You said)

2. Phone needs to wake up little bit faster

3. Decrease battery consumption in deep sleep a little bit but this one is not necessary, 1% per hour in deep sleep is acceptable.
