thanks you for your help, i am new with this mobile i just moved from samsung galaxy, all i did is using fastboot to flash it with the comand fastboot boot arcknight_rc0.img

is it correct or i should do something else
[Xperia Arc Android Development] jimbo77:
You need to do

fastboot flash boot ArcKnight_rc0.img

@All: RC2 coming today, a few fixes here and there and added some interesting stuff as well..

ETA Around 3 hours...
[Xperia Arc Android Development] TheGreatSega:
!!

great!! cant wait!!

!!!

3hours later............

no im just kidding!! love ur work.. by any chance are u gonna use my wifi modules .zip??

would be such an honour!!
[Xperia Arc Android Development] elroysk:
3 hours has elapsed. where the kernel? ;)
[Xperia Arc Android Development] ShresthasR:
Waiting for the release till now, its already 2 AM here, going to sleep now. I will try tomorrow once it released
[Xperia Arc Android Development] jimbo77:
Sorry guys... I'm just solving an error with compilation... But as you know my hardware is not top of the line so it takes its time to do the tasks lol...

I'll promise update will be out today my Timezone :D (Around 5PM Here)
[Xperia Arc Android Development] zpmarcos:
Will try out this kernel when new version arrives :P
[Xperia Arc Android Development] pecholino:
i can't get the wifi modules to work on 4.0.4 :/

has anyone got a solution?
[Xperia Arc Android Development] gen_scheisskopf:
You didn't flash the kernel, you just booted it.

Correct command is

fastboot [B]flash[/B] boot [.img name]

And for your own good- use Flashtool for such operations
[Xperia Arc Android Development] LiquidRobotics:
For everybody who has little problems with fastboot, try the tool doomed151 created for flashing Kernel:

http://xdaforums.com/showthread.php?t=1551073

It is totally awesome and easy to use, its a simple graphical userinterface for fastboot.

No more need to change the name of the .img, no more "waiting for Device" bug, no more typing in fastboot. :D
[Xperia Arc Android Development] Babis_ECE:
While waiting for RC2 to be released :) just a quick question: Which governor and I/O Scheduler do you prefer with ArcKnight Kernel?

My current set-up is:

Max. Frequency ---> 1.4GHz

Min. Frequency ---> 245 MHz

Governor --> SmartAssV2

I/O Scheduler ---> deadline"
[Xperia Arc Android Development] LiquidRobotics:
I´m using conservative as governor and sio as sheduler, this work´s perfect for me. :)
[Xperia Arc Android Development] windmoon:
The RC1 has been mentioned the Governor and IO setting

http://xdaforums.com/showpost.php?p=25864305&postcount=335

Governor: Conservative

IO: VR or SIO

My Setting is SmartV2 and SIO

due to use with Conservative may cause lag

But SmartV2 use more power, so I use incrediblecontrol down Voltage 100 on each MHz "Be careful of the down voltage, this may cause the system become unstable, you need to try your best voltage"

Also I OC my ARC to 1.4 or 1.6
[Xperia Arc Android Development] fearless139:
why the link to RC1 is ArcKnight_RC0.img? Is it RC0 or RC1?
[Xperia Arc Android Development] LiquidRobotics:
It is RC1 "inside" only the Name of the .img is RC0 :)
[Xperia Arc Android Development] collller:
i hate waiting;)

hopefully RC2 will have better battery life. with RC1 my battery was draining 1% for 20minutes. with stock ICS kernel 1% for 3h !

and still RC1 was undervolted, deep sleep working well.
[Xperia Arc Android Development] jimbo77:
Hey There guys...

I just wanted to apologize will all of you since i was unable to provide the RC2 update. My backup computer (The main got broke a while ago) is giving me really a hard time to run Ubuntu inside VMWare Player and every attempt to compile takes as long as 1 hour :O , and if in the end there are any errors I need to re run the whole thing all over again and it´s not only exhaustive but also time consuming.

I´ll be on 2 weeks vacations (From Work) starting today and I´ll be kinda busy with my personal life so no updates will be done to kernel at least until End of Month, Lets hope Sony releases Official ICS sources by that time and I can focuss on that then.

For the time being, the Kernel is pretty stable and fast and I don´t think any other significant improvements can be done to it, I´ve made my best effort to make it good, and for being my first kernel and first real Android development experience it was really good and I think I nailed it :D :D

Anyway, just don´t let the thread die, if you have any request or concern I´ll try to address it and add it when official sources come out or i make an update at the end of the month (Whatever comes first) :D. IF you still want to support my work feel free to do so :) Maybe i can upgrade my F***ing ugly, slow hardware and we all can benefit from it :)

Have a nice Weekend everybody!!!

Try VirtualBox (not OSE version). Make -j4 takes ~15 minutes (virtual machine has 2 cores @2.6GHz and 1 GB ram)
[Xperia Arc Android Development] jimbo77:
Would you mind linking me? I've tried with Virtual Machine once but since the host computer has limited hardware (1 core - Pentium 4@3Ghz and 1GB ram) it can only run with 512mb of ram which makes it run kinda slow :s
[Xperia Arc Android Development] gen_scheisskopf:
Official site

Note- you don't need Extension Pack- basically adds usb2.0 to the virtual machines. Installing Guest Additions (included in installation) on emulated system is recommended though (display driver with seamless integration with host, shared folders support etc)

IMO VirtualBox is better than VMWare Player in terms of performance; also check forums, I think I saw info how to import VMWare machines
[Xperia Arc Android Development] kaatisu84:
Just wanted to say your kernel is awesome - currently using it with TeamXperia ICS-Tweaked. I use smartass v2 and SIO and it runs super smooth and deep sleeps like a baby. Tried conservative but the lag was too bad (probably because I am using MiHome launcher) but anyway, great job and enjoy your holiday!
[Xperia Arc Android Development] doomed151:
VMware Player is a virtual machine. Also, I agree that VirtualBox is much better and faster.
[Xperia Arc Android Development] jimbo77:
Sorry I didn't notice the typo.. I meant to say I've tried with VirtualBox but there was not too much improvement...

Probably because of the Host(?)... Anyways I might give it a try once I'm back at work l, that computer has the double power of my home's PC... Dual core running at 2.6Ghz and also 2GB of Ram :)
[Xperia Arc Android Development] gen_scheisskopf:
From what I remember- kernel compilation on virtual machine with 1 core (cpu was Athlon x2 5200) and 512MB ram took under 30 minutes in VirtualBox. On a single core machine it will take longer of course
[Xperia Arc Android Development] Erm@c:
jimbo77, are there plans to add to the kernel AROMA File Manager?
[Xperia Arc Android Development] jimbo77:
OK guys.... I couldn't stay away from testing too much lol...

So RC2 will be out today I've been using it since this morning, I just need to create new wifi modules. Tonight will be out :D. Been using it with Intellidemand governor and so far smooth and with great battery life..
[Xperia Arc Android Development] vulkanxxv:
Today mean Tonight for me :D

I will sleep early morning
[Xperia Arc Android Development] nasos95:
Hello ^_^

Jimbo, excellent job, your kernel is awesome :D ^_^

Could you please tell us an approximate of when you will be able to upload the RC2 version today? ^_^

Thank you very much in advance :D

Hmm, wanted to test ArcKnight but im a bit confused.

There are three files (RC1.img, RC1-Wifi.img and the Wifi modules that have to be flashed when coming from Doomkernel) but which i have to flash?

Im'm coming from Doomkernel so i have to flash the third file in every case. But which RC1.img? The one with or without the -wifi ending? Both?
[Xperia Arc Android Development] LiquidRobotics:
Just take this Kernel: http://xdaforums.com/showpost.php?p=26018300&postcount=416

and these WiFi Modules: http://xdaforums.com/showpost.php?p=24807655&postcount=2

that´s all you need :)

P.S.: Wenns probleme gibt schreib mir ne pm, auf Deutsch iss einfacher ;)
[Xperia Arc Android Development] bmwbasti:
Thx Liquid,

worked so far ;)

I only was some kind of confused because of the the two posted Wifi files (one "regular", the other one when coming from Doomkernel).

But i found a bug/problem/whatever. When using Incredicontrol it's not possible to change frequency, governor and I/O only voltages work.

Kind regards

Basti

PS.: Now i am wondering if i get rid of the annoying "Android OS bug without having the phone attached to a PC or charger".

PPS.: Danke für das angebot mit der PN, ich komme drauf zurück, falls nötig ;)
[Xperia Arc Android Development] Coolgoly:
Incredicontrol fully works on DooMKernel,on ArcKnight you have to use Nofrills to set frequencies.
[Xperia Arc Android Development] bmwbasti:
I know that but thank you anyway ;)

I was used to only use one only app to be able to controll voltages, frequencies, governor and scheduler.

And (if i got that right) Incredicontrol is the only tool that fits "one for all".

I didn't say that to actually offend him in any way, it's just that he had said he would upload his kernel 2 nights ago, and he just suddenly disappeared without even writing a post :/

We are saying that just out of pure interest about him because we are worried about his disappearance :)
[Xperia Arc Android Development] jimbo77:
Sorry for not updating the Thread up lately, but as I told you I was busy with Home things and my litle girl :D... Anyways!

ArcKnight Kernel RC2 is OUT!!!!

[LIST]
[*]Added Intellidemand Governor
[*]Added OndemandX Governor
[*]Added Lulzactive Governor - Fixed by Bylos - Huge Thanks to him
[*]Tweaked SmartAss2 Governor - Thanks to Bylos once Again, Great Coding Skills!!!
[*]Updated IO Schedulers and tweaked to perform better with Flash Devices - Based on Talon Kernel work
[*]Tweaked OndemandX to provide good performance and yet battery life.
[*]Reclaimed a few RAM MB´s... without breaking Camera :D
[*]Tweaked the Idle min time from 2ms to 1ms so now the phone should go to Deep Sleep more quickly then before...
[/LIST]

There is not to much we can do now, since we are still working with Beta Sources, but PLEASE Test it and provide feedback on how it is performing :D...

Recommended settings for this build:

VR IO Scheduler and Either Intellidemand, Conservative, OndemandX, SmartAssV2 or Lulzactive (Please Test) for good Performance and Great Battery Life, refer to THIS post for Governors Tweaking, for Lulzactive you can use an app called Lulzactive by Tegrak on Google Play Store.

I´ll like to receive feedback on any of the following governors please:

Intellidemand

OndemandX

Lulzactive

Conservative

SmartAssV2

Also I´d like to thank all of you for your support, just look at this:

It´s almost 3K downloads for RC1 in less than 2 weeks!!! I never thought my humble learning experience could get that far :D and if you guys want to support my work just click on "Thanks" Button and if you can don´t hesitate on donating for the cause :D..

Happy Testing and bug Hunting! I expect to receive some feedback :D - Download Links on 2nd Post as Always!

I'm so testing it right now!!!!!!!!!!!!!!!!!
[Xperia Arc Android Development] windmoon:
Testing RC2 now

Thank you jimbo

And just a remind,

when you update to the RC2, remember clean cache and dalvik cache from the Recovery, otherwise your Phone will not Deep Sleep

Cause I tried ... HA... I wonder why my phone don't Deep sleep

after that, I clear cache and dalvik cache is work fine
[Xperia Arc Android Development] sirkay:
@jimbo mate, just some heads up.

ICS Beta source 4.1.H.0.4 for Xperia Play has some differences in some file. so far i notice the diff in:

- arch/arm/mach-msm/rpc_hsusb.c

- drivers/gpu/msm/kgsl.c

- drivers/gpu/msm/kgsl_cffdump.c

- drivers/gpu/msm/kgsl_sharedmem.c

- mm/ashmem.c

- include/linux/cpu.h

- board-msm7x30.c - has io_fraction in 3d0/2d0 gpu pwrlevel

maybe there's good thing if build from this source (if merge with yours). ive tried build kernel for Ray using this source and suceed boot up, but scores doesnt give a good results. i dont believed in scores results, im prefer to real test results. the experiences
[Xperia Arc Android Development] ShresthasR:
:-D
[Xperia Arc Android Development] gen_scheisskopf:
Diferences in kgsl may be worth looking into- on current sources there are some problems with gpu (most visible in Radiant)

new governors :) gonna test all
[Xperia Arc Android Development] ArcMan09:
loved the new awesome governors..!! tested all found that all the new governors are far more better than old dump governors..:D
[Xperia Arc Android Development] sinkster:
I have no 3g with rc2. WiFi's fine, as is signal strength, just booted from rc1 which had 3g. Strange.

EDIT: booted back to rc1 and still no 3g, but apparently there's a mast down locally so that may be the issue.

Dunno what the problem was. I booted dooms v5, 3g was fine. So booted rc2 again and all's well. Good work.
[Xperia Arc Android Development] jimbo77:
Thanks for the tip.. I'll take a look probably next week once back at work and if the phone succeeds to boot I can merge it with ArcKnight sources :)
[Xperia Arc Android Development] shunkawakan:
Hi JJ,

everything works great. Thanks! But can't find the SmartAss V2! Am I blind? Totally weird :-S
[Xperia Arc Android Development] shunkawakan:
I am blind! ;-) The Smartass V2 is listed as 2.

Greets
[Xperia Arc Android Development] Babis_ECE:
Thank you jimbo for another release of ArcKnight Kernel!

Will be trying out the new governors, especially intelidemand and the new SmartAssV2. You suggested VR as an IO Scheduler. Why is that, if I may ask?

FYI, with ArcKnight RC1 and Arconium ICS 2.4 I usually got around 2 full days (48-50 hours) of battery life in the last couple of weeks. Really nice job.
[Xperia Arc Android Development] spromper:
My lt15i boots at 1.4ghz with rc2
[Xperia Arc Android Development] jimbo77:
Check on your ROM.. Look at your tapatalk signature...

You must be using a ROM designed for the Arc S... So the Kernel checks the model through Build.prop to set the CPU frequency at boot :D
[Xperia Arc Android Development] Tarzan-:
Mate, do you recommend using cpu profiles for different events ? Like I have been using cpu tuner, I notice that it don't really go to sleep but keeps at minimum cpu. Also I have noticed lag on RC2 which was not there on RC1.5 using VR and Conservative governor.

Thanks
[Xperia Arc Android Development] jimbo77:
I don't recommend it. I tried myselfa couple of days ago and sand as you the phone was stuck at lower frequencies instead of going to deep sleep....

So I went back to my lovely conservative hahaha and everything is smooth and battery savvy as before :)

Try changing VR to SIO , I have no lag at all using conservative, SIO and OC up to 1.2GHZ...

I've tried with JJ's, doomed Miui and Team Xperia 3.0 ROM :)
[Xperia Arc Android Development] Tarzan-:
Sure, will do.

Great battery life once again.
[Xperia Arc Android Development] jhnjrdan:
Battery life is not great as the versions before RC series, but in RC2, when I connect Wi-Fi, battery seems to last forever. I have one hour with wi-fi connected, and only 1% fell.. No android os issue, and I believe no wifi off battery drain. BTW, I will be using wi-fi forever until I figure out what's this. Could I get some help from you Jimbo77?
[Xperia Arc Android Development] h.debnath:
All custom kernels are based off of ics beta kernel sources and they all have this WiFi battery drain bug when it is disabled, so you must keep WiFi always on.
[Xperia Arc Android Development] fearless139:
Could anyone recommend a combination of governor and scheduler? One little question, do I have to restart the phone after changing governor, scheduler, max freq...?

Thanks in advance.
[Xperia Arc Android Development] h.debnath:
Smartass2 and sio.

And nope
[Xperia Arc Android Development] Erm@c:
I think jimbo77 recommends that: VR as Scheduler and Intellidemand, Conservative, OndemandX, SmartAssV2 or Lulzactive as Governor.

I use Conservative and VR
[Xperia Arc Android Development] Babis_ECE:
RC2 Release works great here. I use Intellidemand Governor and VR Scheduler. :)
[Xperia Arc Android Development] calage1234:
Lag on Official ICS

Hi @jimbo77 i really liked your kernel, but i get lot of lag on the MooDeD ICS rom, on the last version (rc2) i get lag that i never see before. Sorry for comparation but the doom's kernel get faster. Can you improve the speed ? I don't know if the problem is the conservation governor, wich i use Smoothass on doom...

Thanks, i really like your kernel and don't want go to doom (its really outdated).
[Xperia Arc Android Development] h.debnath:
If jimbo77 recommended only you to jump off a bridge, would you do it :D
[Xperia Arc Android Development] jimbo77:
Lol!!

Well if Conservative isn't working for you try any other governors, like ondemand or ondemandx: D
[Xperia Arc Android Development] Tarzan-:
I'm also using his latest kernel on modded ICS and no lags here.

Try different governers and io scheduler. I'm using intellidemand and sio.
[Xperia Arc Android Development] calage1234:
I don't know what's wrong man, i'm using apex laucnher and to open the apps is terrible and when i'm making anything on phone when i'm listening music, the player frezee all the time. I will try another governor like intellidemand.

Or jump of the brigde.... rs :D
[Xperia Arc Android Development] Ivanprskalo:
I think people have bad habit not to mention which LAUNCHER they use before they complain or make suggestions...

I would really like to see new rule over here:

1. If you are about to make comment, suggestion or report lag issue, then please first write flowing:

a) Your ROM

b) Your Launcher

c) governors and schedulers You use

d) others modifications you make such as: supercharge, under-volt, overclock etc..

If people would follow these (simple) rules, IMO it would be a lot easier to developers to help those with questions, reports, bugs and other problems...

And guys, (calage1234) - try this Nemus Launcher. Download it from G.Play. It is a lot similar to Apex and Nova launchers but with less fancy options in launcher settings. On the other hang, NEMUS offers nicest UI and way of handling desktops, and on the top of that, it is fast and lags the least of above mentioned launchers (not to mention, how easy Nemus is on CPU and RAM usage.)
[Xperia Arc Android Development] calage1234:
Yeah sorry man i forget to say the laucnher on the first post, i will try the nemus laucnher, looks very good. Thanks
[Xperia Arc Android Development] fearless139:
I don't think doom kernel is faster than arcknight. I tried the latest doom kernel, I saw it was not as smooth as arcknight, and more important, after some stress test, the phone screen came blank, I had to remove battery to reset :mad:

I used same rom, same launcher, same max min freq, same governor and IO in both test:)
[Xperia Arc Android Development] Tarzan-:
I don't know know if it's my personal choice or slow performance but I don't like custom launchers. I found them resource hog and high on battery. Stock launcher has been great for me, another reason I use modded ICS, because it has stock launcher.
[Xperia Arc Android Development] Gajba:
I've tested RC2 yesterday. It's very smooth and fast but I experienced fast the battery drain. Over night in deep sleep for 9 hours the battery went down almost 20%. On doomkernel the battery goes down about 3-5% over night, using the same settings (frequencies, voltages, governer...).
[Xperia Arc Android Development] darni:
Same here, lost over 20% last night :( with RC2, with v0.8 had no problems...
[Xperia Arc Android Development] gen_scheisskopf:
Yes, it seems that RC2 is using more battery when in (running stock kernel for comparision now).

Jumbo, do you know why your wifi modules are so big? Difference between yours and stock is more than 5MB total (zipped RC2- 5.8MB, zipped stock- 1.5MB)

Tapatalked from my Archos 101 G9
[Xperia Arc Android Development] jimbo77:
I'm not sure why is that honestly, and as per the battery usage I've also noted an slightly increase, probably related to WiFi modules :(

I'll try to revert to previous stock config so WiFi will be included within the kernel and nit as separate modules. Did you noticed the increase in battery usage started when the kernel string was changed??
[Xperia Arc Android Development] doomed151:
I don't think WiFi modules were ever included within the kernel. It just uses the stock modules if you leave the default string.
[Xperia Arc Android Development] gen_scheisskopf:
I'm wondering why your modules are so big (unfortunately I don't have any experience with TI hardware so I can't suggest anything)

I can't pinpoint from which build started to be power hungry (I've tested several firmwares when that change happened). But for sure overnight (12 AM-7 AM, no scheduled tasks, only 1 widget refreshing every 30 minutes + google sync) it uses ~20% of battery, now on stock kernel 25% in 8 hours but ~1.5-2h of quite heavy usage (wifi, market, tapatalk etc)
[Xperia Arc Android Development] jimbo77:
:D That´s what I meant to say, but in other words lol...

Tomorrow I´ll be back at work and i´m gonna run some tests with V8 and V9 - Do you remember the V9 Test version? it has pretty good battery usage - , also i´m planning to check on Xperia Play beta sources to see if I can merge their newest adreno sources into ArcKnight sources...
[Xperia Arc Android Development] Erm@c:
Funny. However it wasn't quite correct. jimbo77 is the author of this kernel and he obviously knows what options better. What I think. So I wrote.
[Xperia Arc Android Development] sirkay:
i succeed build for ray used play source. saw some diff in graphic display, since heard that it has adreno latest driver. if you gonna fork doom's zram driver with patch, better not cos it will make wifi modules cant load.
[Xperia Arc Android Development] jimbo77:
Thanks! Did you find any real improvement after aplying its patches? also for Zram driver I´m not that much into it at the moment, it caused some lag for other devices and seems not to be fully stable :S
[Xperia Arc Android Development] sirkay:
in graphic display, yes. but got little hiccup. will look more into it. zram if its activated correctly, swap space will be populate and stable. my practice was create init.d script to execute last in the list - 99zram
[Xperia Arc Android Development] Babis_ECE:
I son't face any battery drain at all with RC2 and Arconium 2.4, here is my Battery after waking up this morning. :)
