And which version is the overclocked one? ^^

V21 test 2 runs awesome since I flashed it a few hours ago
[Xperia Arc Android Development] DooMLoRD:
both can be overclocked to 2.0 Ghz
[Xperia Arc Android Development] Ninolina:
I am using v21 test 1 for a few hour now and it runs great when not overclocked. I didn't had any reboots or problems. But when I overclocked to 2.0 Ghz it reboots.:-(

Thanks...:-)
[Xperia Arc Android Development] Flo95:
I know, I made a writing mistake.

I meant gpu overclock and forgot to write gpu, sorry.
[Xperia Arc Android Development] chitose_ndy:
im sorry im a noob,

but ive test both test kernels and want to tell how it was

--

ussually, my free memory that shown on the task killer is around 170 - 185

using first test kernel, the free memory becomes only around 120-160

using second kernel, the free memory is still around 170 - 185.

--

using the first test kernel, i encounter more lag and skipping animation, if u kno what i mean :p

using the second test kernel, it runs only a few lags, but better than the first test kernel

--

and for about 1.6 and 2.0 hz overclock,

using 2.0 version sometimes random reboot

--

that's all, thanks ;)

Using #3021.. No battery drain while idle.. Benchmark scores :

Quadrant - 1444

Nenamark 2 - 15

(184MHz - 1.402Ghz)

I had no reboot after using it for 10hrs..
[Xperia Arc Android Development] davibs:
Reboot with 1.8oc..
[Xperia Arc Android Development] X-Droidinary:
I installed 3021 and so far no problems bit I'm not sure what frequency, Governor or I/O Scheduler to have my phone on. As it is I have the frequency on 1.114 Max GHz, 249MHz Min, Governor Ondemand and I/O Scheduler cfq.

@DoomLord:

Your Kernel V20 work so good ^^
[Xperia Arc Android Development] doomed151:
Only tried NenaMark2:

249 min / 1.402 max / ondemand / deadline

v21 #2021: 14.5 FPS (3 tests average)

v21 #3021: 16.1 FPS (2 tests average)

That's quite a nice gain.

I flashed doomkernel V04 for ICS with modules for wifi...I was going to flash FXP115 CM 9.0 so flashed the kernel included in zip file after flashing stock modules.but the screen was black after turning on the phone,nothing happened,so I flashed doomkernel again & everything is ok.what is the point?
[Xperia Arc Android Development] Flo95:
This is the GB's kernel thread
[Xperia Arc Android Development] everb00b:
#2021 working great, no problems on the Arc.
[Xperia Arc Android Development] eksen:
I install linux instead of windows to delete the fastboot can not install the kernel. Doomkernel how to install linux kernel? (Flashtool or cwm recovery)
[Xperia Arc Android Development] spit85:
Android is Linux based, so you can't installed windows on your arc
[Xperia Arc Android Development] matus201:
I am pretty sure it was asked here before, but i didn't find the answer:

Flashing this kernel, does it erase phone memory (data)?

Thanks!
[Xperia Arc Android Development] spit85:
No, the data maintain.

If you installed supercharger or a2sd, or some kind of that software, that must installed again, but apps and data maintain on your phone's memory
[Xperia Arc Android Development] Coolgoly:
Kernels on arc can't be flashed via flashtool or cwm,only fastboot.
[Xperia Arc Android Development] ascariz:
what you all testing......? speed? what doomloard need, is stability at 2.0GHz. i think if you want a stable state at 2.0GHz, you need to adjust the voltage. that's what you all need to test..set at 2.0GHZ, if it not freeze, then try run benchmark like antutu, it will make you stuck at GPU test. but if you pass it, please post the voltage that you used..
[Xperia Arc Android Development] spit85:
That is no good idea. Maybe for the Arc S users, not for the Arc users. When I overclock my arc at 2Ghz (that's 100% overclocking) , I will brick my phone.
[Xperia Arc Android Development] DooMLoRD:
No no no...

You guys have to test two things:

1) If the new test kernels boot on ur device

2) which one performs better graphically (gaming/UI experience)
[Xperia Arc Android Development] davibs:
Xperia Arc : Boot.

Second Kernel better graphically.

Random Reboot when OC at 1.8..
[Xperia Arc Android Development] DooMLoRD:
Kindly mention the kernel version number (#x021) which u found to be better...
[Xperia Arc Android Development] deepthroat:
Thanks, great job !

edit: with #3021 temple run does not lag like before LOL
[Xperia Arc Android Development] rkanwar:
Just installed v19 bfq schedular and smartass v2 governor. I will report after 24 hours. I will probably install v21 soon. Do I stick with the wifi modules(v15 onwards) for v21 kernel?
[Xperia Arc Android Development] Flo95:
Yes, as DooMLoRD wrote.
[Xperia Arc Android Development] matus201:
Does somebody know where to get stock modules for FW .62? The stock modules on first page are for .42 ..

(or somebody can tell me how I can extract them myself?)

In other words, I was on stock .62 and only changes I have done is that I installed DoomKernel (with his modules). Now I want to go back to stock kernel as I was before. What is the best way without loosing all user data? Just use flashtool and select to not wipe phone memory, or will that mess things up?

Thanks!
[Xperia Arc Android Development] rkanwar:
heres my report of v21 3021 and 2021

as everyone else so far has stated 3021 performs better however everytime i overclock 3021 even to 1.5ghz i get reboots when playing any game and a few lags

Edit: on any version if I change to smartassv2 and bfq, oc or not my phone becomes unresponsive and reboots.
[Xperia Arc Android Development] volant:
hopefully doom can come up with a final release of his new kernel soon. thx for your effort doom.
[Xperia Arc Android Development] rkanwar:
In contrary to my previous post, I have installed v19 (2.0GHz) version oc to 1.7GHz, uv by 50mv, using ondemand and deadline. Last night my battery drained fast. Charged it to 100% this morning, and now my drain I am yet to evaluate. Im waiting for my battery to die down to about 10% which is when I usually start charging my phone. I will provide the battery stats log if someone is willing to have a look.

Oh and wheres v20? I cant seem to find it. I still experience lags on some games. Temple run runs so smoothly.

Hope this information is helpful
[Xperia Arc Android Development] DooMLoRD:
dont test the devices at 2.0 GHz!!!!

just check if the kernels boot!
[Xperia Arc Android Development] rkanwar:
Ive not oc'd to 2.0ghz only upto 1.8ghz
[Xperia Arc Android Development] eliseo.cuadrao:
Using Go Launcher v21 (3021) the smoothness changing screens sometimes lags a bit.

For me the best Kernel from doomlord is the V19 v2. with that kernel go launcher and all apps i tried works very smooth

EDIT: Smooth with Go Launcher seems to be the same as with v19
[Xperia Arc Android Development] rkanwar:
Hi guys okay heres the deal.

I have a xperia arc s oc to 1.7ghz, uv by 50mv on v19 of the 2GHz kernel.

My battery is on 21% at the moment. Time since unplugged is 6h 53m 52s.

Bearing in mind ive been playing temple run half the day lol. but anyways i have attached my betterbatterystats log if someone is willing to look at it and tell me what the progress is like? i.e. is it a good drain or bad.

P.s. im using ondemand governor with deadline schedular. if i change any of this my device becomes unresponsive.
[Xperia Arc Android Development] Flo95:
Thanks for 3021 DooMKLoRD!!

My Arc stopped to lag all the time, just some little lags here and there left :)
[Xperia Arc Android Development] rkanwar:
guys in about half hour im going to flash v21 3021 again and give it another go. can anyone recommend me good settings for performance as well as battery efficiency. I agree that every device is different however its just guidelines i am wondering about.
[Xperia Arc Android Development] spit85:
V21 have less battery drain then V20, I'm glad about that. I think 3021 works better on my arc. When I'm gaming, it's smoother whit 3021, but otherwise I don't see any difference between version 2021 and 3021.
[Xperia Arc Android Development] cx-11:
Hy at all

Finish to testing #3021

booting = Yes

reebots lags = No

WIFI= OK ( V19 better signal maby fake)

Battdrain= a greenphone nice (better then V19)

Snappy for using on original supercharched buil.69 bsb.66 2.3.4 Rom using

134Mhz to 1.2GHz - SmartassV2 - noop

Right now Flash #2021 Kernel for testing report tomorrow

buddys sorry for my english THX

Doom for your work again again
[Xperia Arc Android Development] rkanwar:
Ive flashed 3021 last night. Same as the above posts. Wicked kernel. Oc to 1.6ghz uv by 25mv and my battery is unplugged 11 hrs and 10 mins im still on 43% usually id be in the 20/30s.

Just had one random reboot now. Governor and scheduler have been reset
[Xperia Arc Android Development] amulbaby:
VIRUS..HELP

Hello,

I installed DooMkernel, latest version on my ARC and then installed ZipITv11 script...

and as some users have posted, KEYPAD IS VERY LAGGY...

Model number had changed to LT18i ...and I edited Build.prop to change it back to LT15i...

I ALSO FIND THAT MY ANTIVIRUS DETECTS SUPERUSER AS A THREAT....WHATS TO BE DONE? IS THIS RELATED TO THE KERNEL OR THE SCRIPT?

Please lemme know how to uninstall this script...Will it be overwritten if I restore my Nandroid backup?

Thank you
[Xperia Arc Android Development] Muurahainen:
Well you can count superuser as a threat.

It gives you and your software superuser rights and that could be harmful in wrong hands.

Exclude superuser in your antivirus.
[Xperia Arc Android Development] Flo95:
This is a kernel thread, not the one for the script.

And yeah, restoring the backup will remove the script
[Xperia Arc Android Development] rkanwar:
Guys after a reboot I got the notification that unclean values were applied. What does that mean? When I checked nofrills, governor and scheduler were changed back to ondemand and deadline
[Xperia Arc Android Development] DooMLoRD:
the kernel and scripts which i have implemented are done in such a way that even if users dont want to overclock all setting will be, by default, stock like... so at every boot:

CPU Min freq: ~245 Mhz

CPU Min freq: ~1 Ghz (ARC) / ~1.4Ghz (ARC S)

CPU Governor: ondemand

I/O scheduler: deadline

its upto users to select wht they want to use...

this is the ideology behind my kernels... thats why "Power to the People" (i am sure the X10 guys will remember this) ;)

as for that "unclean values" notification, its NoFrills app...
[Xperia Arc Android Development] amulbaby:
Hey,

thanks for the reply...I knw this thread is not for the script..But I didn't know whether the virus was a issue related to script or the kernel coz I had installed one after the other ...Sorry ...

And now I got a clear idea of what was happening...

Awesome kernel ...Plenty thanks to DooMLoRD...

Gonna stick to this kernel and awaiting more from DooMLoRD...

Good day

[Xperia Arc Android Development] mando508:
Mostly gameloft games are laggy with oc custom kernels, i don't know really why ; x.

http://www.youtube.com/watch?v=nCK0dvRbTHI *notice that there's no popup when using doomkernel [everything is loaded in ram - so maybe it's too much for our phone and it's starts to lag]. Huh maybe it's is something with ram managment in kernel not OC?

Both #21 acts the same. For everyday use it's great kernel (really fast), but gaming performance in demanding games is low.

DooMLoRD figure out something! :D
[Xperia Arc Android Development] rkanwar:
Thanks doom. I have no issues really just wanted to clarify that one thing. Only the governor and and scheduler change. The oc values stick at 134mhz and 1.6ghz
[Xperia Arc Android Development] cx-11:
Hy at all again

Finish to testing #2021

booting = Yes

reebots lags = No

WIFI= OK ( V19 better signal maby fake) same as #3021

Battdrain= same as ( V19) #3021 better then #2021 with #3021 in deepsleep still no drain for 3h with #2021 just 2h

not so Snappy like the #3021 (similar to V19 feel like) using on original supercharched buil.69 bsb.66 2.3.4 Rom using

#3021

battery drains fast, even when screen off, battery lasts 5 hours with my usual heavy use.

when i was on ver19, lasted 9-13 hours
[Xperia Arc Android Development] Ninolina:
I have a very good battery lire with #3021. It's even better than with any version before. Are you sure it's not some app or ROM that is responsible for your battery drain?

DoomLord,

both versions of v21 are pretty much good on my ARC S. Both boot without problems and I feel a little smother playing games with #3021. As I mentioned before, only had a restart if I overclock it.

Thanks for your work...:-)
[Xperia Arc Android Development] Mesho Arc:
I'm using arcomium 8.1 ROM maybe its the problem
[Xperia Arc Android Development] spit85:
I must say that V21 (I use V3021) have a very good battery life. I have installed JuiceDefender also, and when my battery is at 100% when I go to sleep, it's by 95% when I awake, 10 hours later. With V19, also installed JuiceDefender, my battery was at 91% or 92% when I awake.

I have notice that V3021 is better with gaming then V2021. When I playing Asphalt, from Gameloft, the game sometimes freeze with V2021, but with V3021 not. When I oc to 1.2Ghz simple games like angry birds sometimes freeze, but if I oc to 1.4Ghz it not freeze.
[Xperia Arc Android Development] DooMLoRD:
so guys i think adequate testing is now done...

i am sure as most of u would have realized that on MOST device #3021 kernel preformed better...

and thats because:

#2021 - GPU OC was PRESENT

#3021 - GPU OC was ABSENT

so hence forth for all future kernels i will be removing GPU overclock...

ALSO, since both the kernels booted up fine on ALL devices i am stopping the 1.6GHz version as now the kernel has the patches to make the device boot even when using 2.0Ghz kernel...

THANK YOU ALL FOR TESTING!
[Xperia Arc Android Development] spideras:
Doom do we stay with the 3021 test kernel or you do your magic again to release a final?
[Xperia Arc Android Development] DrearierJester1:

After instaliing doomkernal v19 some of my apps such as music player, widgetlocker, file expert and system utilities... seem to crash...

:confused:
[Xperia Arc Android Development] doomed151:
Not so shocking for me. I kinda expected it because when GPU OC was introduced previously it caused benchmarks to go down by 1-3 FPS.

Anyways, great work with the kernel. I did notice some irregularities especially with bootup clocks. It tries to set the default clocks to 245/1024 MHz while those freqs don't even exist in the table (closest being 249/1018 MHz). This causes the governor to spit out errors to logcat and also causes tiny stutters in the UI (I think). Hope you can look into this issue. Thanks.
[Xperia Arc Android Development] DooMLoRD:
Thats interesting... Can u post in detail when this happened? Also post logcats whenever possible
[Xperia Arc Android Development] doomed151:
Sure, after I reach home tonight. :p

Really miss it.
[Xperia Arc Android Development] basketballman:
a small question

isnt GPU oc a good thing?

i think it's supposed to be better

but why 3021 had better performance?
[Xperia Arc Android Development] DooMLoRD:
this is a very good question...

GPU OC is a good thing, but sadly this chip (adreno205) isnt good at handelling such GPU overclocks... what happens is, it tries to run faster but keeps failing, that why u notice slight lag in overall performance when using GPU oc...

and again since not all hardware are equal some devices dont lag, while other do...
[Xperia Arc Android Development] DooMLoRD:
hu? so in the new CWM restore isnt working at all? even for the backups which are dont by this new cwm?
[Xperia Arc Android Development] babygau:
here is what I've done

At first: I used v5 kernel to restore my v4 backup, it didn't work with the error I told u b4

then I did backup using v5 <~~ here it said "complete backup" so I thought the v5 worked OK with backup/restore feauture

however, when I used v5 to restore both v4 & v5 backup, they both were not successful ( it couldn't format /data again)

So, I flashed back to the v4 kernel, restored both v4 & v5 backup as I said above, It worked perfectly

As a result of that, i think v5 got some issues with restore feature

Do I lighten u a bit??? :)
[Xperia Arc Android Development] tRippinthehead:

[Xperia Arc Android Development] vitaminme:
Finally i could reply in dev post. :)

Since couple of days i've tested FW:4.0.A.2.368 with all kernels, battery used to drain like anything.

Today i downgraded to FW 145 and using V4 kernel, since last 1 hour battery is at 100% :)

used set cpu at 1555 max (on demand)

Think firmware 368 is draining loads of battery. it used to drain 2% in less than 10 minutes.
[Xperia Arc Android Development] babygau:
Welcome back, Vitamminme :) also read the msg from u.

You r on the money about that, however, setting cpu profiles also help me save a lot of battery consuming, moreover, u better remove some software like updatecenter, fun&download widget, weather widget ... i found they are battery killers :)

PS: busybox installer cannot install new 1.19 version, it reported successful install but the old version 1.16 still remained
[Xperia Arc Android Development] Flo95:
I think I'll update soon and unlock my bootloader for this.

How much overclock is save for the Arc?
[Xperia Arc Android Development] DooMLoRD:
u can try removing the buysbox binary from /system/xbin/busybox and then using busybox installer...

BTW 1.19 is not recommended... 1.18 is better version...

also the inbuilt busybox v1.16 is in /sbin/ and will always reside there as recovery depends on it...

1.2Ghz is SAFE... 1.4Ghz is slightly unsafe... anything beyond is pushing ur own luck :P
[Xperia Arc Android Development] babygau:
Running stable with 1.5ghz ;)
[Xperia Arc Android Development] babygau:
Just delete busybox in /system/xbin and install 1.18 but busyboxinstaller still show the older version :(
[Xperia Arc Android Development] DooMLoRD:
how are i checking busybox version?

also in PATH variable the /sbin/ has precedence over /system/bin/ OR /system/xbin/
[Xperia Arc Android Development] babygau:
the version show in busyboxinstaller

Your device is rooted

dont worry bro... all necessary stuff is already in place... i doubt u will run into issues... if u do run into problems tell me the exact app and we will see wht can be done ;)

is GPU oc the same as GPU rendering?
