Is it 100% confirmed that the GPU clock actually changes?

Also I agree with you, lower performance at higher clocks could be caused by built-in error-correction methods (to prevent artifacts). I'm not an expert in this field, just guessing.
[Xperia Arc Android Development] DooMLoRD:
yes the clocks are updated... but we dont have an interface at the moment to check this at runtime..
[Xperia Arc Android Development] basketballman:
i cant wait to try 3.x kernel :D
[Xperia Arc Android Development] alfiemenace:
v3022 has been great. Just one question doom, did you make any substantial change to data connections? Mobile data to be exact? Because with v19 I can have mobile data but when I flashed v21 mobile data has been hard. Thanks for replying!
[Xperia Arc Android Development] DooMLoRD:
Nope... Nothing relating to data has been touched on any of my kernels...
[Xperia Arc Android Development] Mesho Arc:
Thank you DooMLoRD

Why did you go for Xperia S while there hTC One S or One X?
[Xperia Arc Android Development] DooMLoRD:
i bought the HTC One X for personal use... the Xperia S user community donate a device to me for development ;)
[Xperia Arc Android Development] alfiemenace:
awesome compensation :) a little OT, from what country are you from and are you a computer major? :)
[Xperia Arc Android Development] DooMLoRD:
India... and no i am not a computer major ;)

Which is better for stability, v19 or v21 #3021?

Hi DooMLoRD,

Just a quick question... I am using this kernel and one of my priorities is stability. Right now I am using v19 overclocked to 1.4 Ghz and undervolted -75mv and my device is rock solid (I use it under baseband 64 and no problems whatsoever, stock ROM 62).

A few days ago I installed v21 #3021 and using the same settings as with v19 the device is rock solid also. But the thing is that I see that for you v21 is a 'testing' version, so I am not sure if I should use it on a 'production' device. If everything works ok, do you think it safe to use v21 #3021? Should I stay with v19 and wait a few days for a new stable version?

Thanks!!
[Xperia Arc Android Development] DooMLoRD:
well... #3021 is very stable... i was test other things...
[Xperia Arc Android Development] indrajeet007:
Solved it by myself..... thnx for the kernel !!!
[Xperia Arc Android Development] omarfaieq007:
guys are there any tweaks to increase performance and manage ram?I managed to root and install CWM but I am still on locked BL,so I can't flash a costume kernel(like DoomKernel) and that's why I need any way to boost my device's speed and RAM stabilty...thanks for any help provided..
[Xperia Arc Android Development] spit85:
Wrong section. Search on XDA and you will find something.
[Xperia Arc Android Development] omarfaieq007:
Thank you so much..but I'm desperate here all kernels need Unlocked BL:( that's why I posted here for any guidance..thanks anyway my friend
[Xperia Arc Android Development] spit85:
There is no tuning in cpu speed if the bootloader is locked. You can download a taskkiller that you can use if the phone is slow, but that is not the best option. You can unlock your bootloader with a tool, sow you don't lose your DRM, and afterwards you can relock it again. That is a option if you worried about the guarantee. With unlocked bootloader you can do more to tune your phone, like custom kernels.

You can try supercharger http://xdaforums.com/showthread.php?t=991276

Hi All

Plz guys help me ...

this problem is really bothering me

( my Phone info at the Moment: Arc@ Arconium v8.1 - Doomv21 - OC 1.4/Noop - Baseband 64 )

i've faced to

low performance in some games

for a long while, even in some games i didn't expect that like "Ninja Fruit", i said espically Ninja Friuts because i know at least all of u guys played this for one time !

while i played this game, after few seconds,

the lags and (espically) delays will appear

!! and really it's Annouing that My Arc with 1.4 OC can't handle a game like that !!!!

Ofcource, without counting this issue, performance of All part of my phone in usual using is great, pretty lagless and smooth .

..

Actually i tested it with diffrent governors Or Doom Advance stock kernel and Also i did deffrent wipe but it didn't work (except Wipe Data because i don't wanna lose my data apps)

Doomlord give me some idea, please ....
[Xperia Arc Android Development] DooMLoRD:
try the #3021 kernel...

and while gaming always use performance governor
[Xperia Arc Android Development] iAchilles:
actually i did that already, and i was on #3021 all the time

and again i did it, but the result was same and problem is stable and after fwe second (while playing) the game goes slow down and the screen will show ur thouchs with some delays ... !!

! ? ? ?

btw, i should add this

Ofcource, without counting this issue, performance of All part of my phone in usual using is great, pretty lagless and smooth ...
[Xperia Arc Android Development] DooMLoRD:
are u having same issue on stock kernel?

try disabling all services and reducing background running apps to a MINIMUM
[Xperia Arc Android Development] iAchilles:
as i told u, i teset it on ur advance stock kernel and i think ur adv stock kernel isn't veey deffrent with orginal sotck kernel

shall i test it on orginal sotck kernel !?

i have ARC_4.0.2.A.0.69 ftf, the kernel in this ftf, is it ok !?

ur kernel is base on this kernel !??

--------------------------------------------

i closed apps by adv. task killer and off all service like gps, wifi, ... (which ofcource already all of them was off) and using 2G AND tested it again but dindn't work

any particular meaning do u have for "background running apps" !? i closed app by adv task killer, is it ok ? ...
[Xperia Arc Android Development] DooMLoRD:
if u have same issue on stock/advanced stock kernel then i cant do much...

ask ur ROM dev...

if u using stock ROM then install a cleaner stock based ROM
[Xperia Arc Android Development] iAchilles:
actually i didn't test on stock kernel instead of that i tested it ur adv stock kernel

shall i tested it again on stock kernel ?! ihave .62 ftf is it ok !?

i'm on Arconium v8.1 !!!!!!!! wht is ur sugestion !??

---------- Post added at 11:23 PM ---------- Previous post was at 11:20 PM ----------

There is another thing that i think it's directly related to kernel ....

when u'r playing this game

even

u pause the game, after passing few secs u will face to that issue too ...

does it mean something !????
[Xperia Arc Android Development] DooMLoRD:
advanced stock kernel uses the kernel (zImage) from stock kernel so its performance will be same as stock kernel...

suggestion: overclock more...
[Xperia Arc Android Development] iAchilles:

on 1.9 OC : device got reset !!!

i think it doesn't depends on OC, because on 1.7 surely it has to run it smoothly ! Right ???

in ur opinoin, what things cause a issue like that !?
[Xperia Arc Android Development] DooMLoRD:
do a fresh install of ROM??
[Xperia Arc Android Development] iAchilles:
with what wipes !?

actually i just installed this rom (arconuimv8.1) recently and the point is, i have this issue from arcounim v7.1 and i hoped to fix in v8.1 but it didn't

So, .... is it neccesery do "data wipe" on installing !? will it help to this issue !?
[Xperia Arc Android Development] mando508:
I've the same problem in games with kernel that contains overclock, use stock kernel for games and you'll have no problem.
[Xperia Arc Android Development] iAchilles:
actually, i tested with stock kernel of .69, but the problem still exists !!!

I think it depends on ur rom ! which rom r u using !?

---------- Post added at 12:50 AM ---------- Previous post was at 12:44 AM ----------

DoomLord, i got a question

if i just wanna update my baseband by a ftf file, which files is related to baseband in a ftf (.69 fw ftf) ??

here is the files in .69 ftf

is it right if i just delete simply extra files that is not related to baseband !???

ThX a lot
[Xperia Arc Android Development] X-Droidinary:
You're better off flashing a baseband .ftf and then installing the zip in recovery mode.

Yeah significant drain... Like 1 % per 5 min when used and 2% per hour in idle state..
[Xperia Arc Android Development] spit85:
I use JuiceDefender, that works fine for me, to minimize the battery drain.
[Xperia Arc Android Development] terranox:
I use internet all time, juice defender isnt a alternative.

Enviado desde mi LT18i usando Tapatalk
[Xperia Arc Android Development] iridaki:
Every time somebody suggests Juice Defender, I'm like:

:D

However, for light usage like email, chat, WhatsApp, turning 2G-only on helps a lot, especially in low signa areas.
[Xperia Arc Android Development] vifer06:
Just want to know why NO for Juice Defender? :D
[Xperia Arc Android Development] iridaki:
Because personally I need my data on all the time for push notifications (Gmail, Gtalk, Whatsapp etc).

Secondly, even if I decided that a 15 minute delay is not that much of a big deal,

having an app running constantly, turning my data on and off every 15 minutes, is itself a strain on the CPU and the battery.

During my trials, I never saw benefit from such apps.

On the other hand, turning data completely off manually before I got to bed, gives me the same -and maybe increased- boost.
[Xperia Arc Android Development] vifer06:
Turning data completely off means? Sorry quite a beginner here. :)
[Xperia Arc Android Development] spit85:
My battery drain isn't so much with JuiceDefender installed on my phone. I have much apps that need Internet connections, just like you, what's app, mail, and that. And in intervals from 15 minutes, sow date isn't on all the time, gives me a few % more at battery life in a few hours.
[Xperia Arc Android Development] DooMLoRD:
check ur app list....

while reporting battery issues refer to the links in first post on how to post such reports...

BTW we had resolved battery draining bug a few months back...

if u want EXCELLENT battery life:

undervolt

underclock (dont over-clock)

use MINIMAL apps

increase sync durations

use 2G (GPRS/EDGE) mostly

DISABLE "Automatic Network Selection"

DISABLE "Automatic Time from Netowrk Provider"

since ICS has been out for ARC S and most ARC users are also using it, i wanted to know if anyone is still interested in this kernel for GB based ROM?

if not, i can shift focus to ICS kernel...
[Xperia Arc Android Development] doomed151:
I guess it's safe to do so since your last test kernel is stable enough.
[Xperia Arc Android Development] Flo95:
Yeah, 3021 runs super stable and fast.

I'd say you can focus on ICS now :)
[Xperia Arc Android Development] kurnage:
Agreed, this kernel is great you have served us well with GB. Lets see what you can do with ICS :D

Your work is always much appreciated here!
[Xperia Arc Android Development] Ninolina:
Well, I am interested, since I won't be switching to ICS for some time. I like GB more. I hope my vote for GB kernel do count...;-)
[Xperia Arc Android Development] terranox:
Me too +1 (((GINGER BREAD POWER!!!)))

Enviado desde mi LT18i usando Tapatalk
[Xperia Arc Android Development] DooMLoRD:
Most features of my GB kernel are already integrated in ICS kernel... It's just that I have some new patches to test out, so if most testers have shifted to ICS then it's better for me to shift to ICS... It will save me a lot if time...

Lets see, may be I will keep this kernel updated for a month or so then shift fully to ICS...
[Xperia Arc Android Development] spit85:
I still use the GB kernel for a month ore 2, in that time I still testing the GB kernel.

Hi

I just wan to say THANK YOU DoomLord for your great work :) your latest 3021 is the fastes kernel i've tested :) currently im on official Arc S ICS but this is like upgrading years ago from XP to Vista... so slow, laggy, even games are lagging :( im thinking about flashing back to GB with your best so far kernel 3021 :) (Reckles Racing 2 is ultra super smooth with it :D).

I cant wait your new kernel for ICS, maybe then it will be more usable... :)

Weired USB-Brick and No-Network

Hi there,

I have a problem with my Arc S LT18i; which I don't know how appeared. My guess is that it apeared because of OTA update (because the user is not admiting that he tried OTA/SEUS update)

I feel this is a kernel/baseband incompaitability problem but not sure.

When I sold this phone to user, I installed following kernel and modules. But which baseband, I don't remember but I guess it was 36.

ARC-DooMKernel-v15-high-modCWM-04_boot.img

ARC-DooMKernel-v15-modules_CWM.zip

ROM:XPERIA MOD™ =- [Tweaked Ultrafast & Smooth 2.3.4][Ver. 3.0]

Currently phone is showing following:

2.6.32.9-DooMKernel DooMLoRD@chaos#15

Baseband 56(See attached Screenshot)

Phone is rooted, bootloader unlocked with DoomKernel CWM 5

Here are the problems I am facing:

- Phone will not connect to network (says No Service). Tried 4 different SIMs. If i search and manually select network, it will show signal but then drop as soon as I try to make call and there will be cross mark on cellular icon.

- Phone will not connect to computer(Vaio win 7 64bit) via usb. When I connect to pc via USB, charging starts but computer will not detect the phone and on phone also no indication of USB connection aparat form Battery Charging icon.

.Tried USB debuging on/off

.Tried Driver Re-Install (Meaningless as phone is not showing up at all on PC but still tried)

.Tried on 2 other PCs, (XP and 7 32bit)

.Tried fastboot (Hold menu and connect USB, i see blue light, but on PC nothing happens)

.Tried Flash mode (Hold back button and connect USB, I see green light, but on PC nothing happens)

Now I am not able to flash anything apart from ROM so can't return/update to stock/other kernel/baseband.

Any help would be life saver for my phone..
[Xperia Arc Android Development] DooMLoRD:
well u need to try another PC...

fastboot and flashmode are NOT kernel related so most probably its a hardware fault...

i ha similar issues on my brother's SGS2... the USB port had short-circuited so had to get it repaired...
[Xperia Arc Android Development] mahesham22:
Well, as I said in my post, i tried on 3 different PCs,

DooMKernel v22 released!

DooMKernel v22 released!!

[ feature/changelog ]

updated ramdisk scripts to correct superuser permission and to properly install busybox (1.18.4 full) in /system/xbin/

re-enabled debug sysfs

updated to patched ZRAM (thanks to faux123) [details on how to use it, here is a recovery flashable update.zip to enable it]

added Fugeswap to lowmemorykiller (thanks to LeeDroid-)

removed GPU overclock

bootup CPU frequency fix-up now at kernel level so no more need for having two separate versions of same kernels (1.6 GHz and 2.0 GHz), both are now merged into one :D

merged 4.0.2.A.0.58 & 4.0.2.A.0.62 FW kernel sources (not really any major changes)

u will have to flash the

"v22" modules

to get WIFI to work and for the device to boot!

download links at first post!

please test out and let me know you feedback!!

this will probably be the last kernel for GB unless i get some awesome patches which can be applied ;) most updates will now be done for ICS kernel... ICS kernel will soon be updated with these features..

[Xperia Arc Android Development] lzyllp:
maybe the kernel size error？
[Xperia Arc Android Development] sirkay:
nope .. its probably cpu freq and vdd levels

flash working kernel first, then try set cpu freq at 1Ghz/max 245Mhz/min and select "Apply on boot" using any Cpu Control Apps (NoFrillsCpu)

then flash v22 and let see if it booting

[Xperia Arc Android Development] DooMLoRD:
wow!

damn...

does it boot for anyone?

this kernel was compiled with cpu-freq fixup patch, which we tested in kernel v21...

those having booting issues please check the following:

1) verify that the md5hash of the file u download matches the md5hash posted in 1st post

2) did the previous 2.0 GHz fail to boot on ur device?

3) i hope u realize that this is a GB kernel, NOT ICS... so it will only work on GB roms...

i am also verifying the file again to see if the upload was corrupt...

just checked... file was uploaded correctly and it boots fine on my ARC (LT15) atleast on clean .62 FW
[Xperia Arc Android Development] doomed151:
Did you even try it on your device? Just wondering because it looks like your device boots the kernel fine.
[Xperia Arc Android Development] DooMLoRD:
i was on ICS before so flashed to stock FW .62

it was booting yesterday when i tested before upload

and even now when i downloaded it from server its booting fine on clean .62 FW...

let me check... i have an older GB backup will revert to it and then try if kernel boots...
[Xperia Arc Android Development] sleepsus:
DooMLoRD, is the compression rate configurable? Or does compression rate even matter here?
[Xperia Arc Android Development] Qwerty123 \m/:

@DoomLord please fix :)

the default compression used for ZRAM is LZO, and faux123 has tweaked this driver A LOT.. so its already pretty optimized!

huge thanks to faux123 for this!
[Xperia Arc Android Development] DooMLoRD:
ok so i did some more testing...

on clean .62 FW first flashed v22 kernel... it booted fine

then flashed v21 (#3021) kernel... it booted fine

then flashed v22 kernel again... it booted fine

now will test on older backups
