What data corruption are you facing? (Extractly, what do you mean data corruption?)

I haven't seen any1 complain about data corruption in this thread!
[Sony Xperia S, Acro S, Ion] fajarep:
based on my experience, data corruption for crash kernel can be like "factory reset" feel(i mean, you're forcing to reconfigure gmail) or when you're playing game and get crash, game can't be loaded again(need to be clear data)... i'm saying because of my experience with kernel dev in my latest phone, got several times "factory reset" feel after crash..
[Sony Xperia S, Acro S, Ion] edowar:
Will be kindly if you sent some log files for data corruption, so it will more easy to discuss.
[Sony Xperia S, Acro S, Ion] DooMLoRD:
i have been getting feedback for my kernels for Xperia X10, ARC, PLAY, NEO, MINI, MINI PRO, RAY; Samsung Galaxy SL; Huawei Ideos X6; Kindle Fire; HTC JetStream, Flyer and now Xperia S and this is the FIRST time i have heard of any such speculation...

my kernel wont cause a "factory reset"....

as for ur experience, well its ur experience ;)
[Sony Xperia S, Acro S, Ion] poo-tang:
Erm I know in your experience that has not happened and I know it should not do that (got most of the Xperia,s you mentioned never happened to us before). But we unlocked another S to the one I am currently using the other day. Only issue was when we flashed the first Kernal 1a via fastboot we rebooted the device and all was like fresh out box, it had wiped it all. At the time I thought mite have been something to do with a bad flash or something. Did not take any notice of it till sore you talking about it.

Off topic - Ps also got a 3rd unlocked S but it seams f#cked fastboot works and unlocked but won't ever go into flash mode anyone have ideas about that - off topic
[Sony Xperia S, Acro S, Ion] DooMLoRD:
did u reboot the device and check after unlocking bootloader? unlocking bootloader WILL do a factory reset :)
[Sony Xperia S, Acro S, Ion] poo-tang:
My bad you could be right got to many phones I lose track what's going on, that's why did not take notice then. :confused: :) sorry about that. :)

Something of use

001 test: works fine no reboots in games and noticed the device stayed cooler (processer by camera) to the touch.

002 test: working fine so far no reboots yet

Will keep testing :)
[Sony Xperia S, Acro S, Ion] fajarep:
:D i just said this is my experience and you'll get more experience in google about data corruption when kernel get crash..., lots in xda. but normally, it only affect in /data or /cache area cause those area is in rw access as default, while /system won't affect because usually in r mode :)
[Sony Xperia S, Acro S, Ion] marcjuh:
hi all 've been reading this and besides all the know how just wanted to remind something evry1 can read in the OP of this thread...

[ disclaimer ]

OVERCLOCKING CAN BE DANGEROUS! U RISK THE HARDWARE GETTING DAMAGED!

PROCEED WITH CAUTION! U HAVE BEEN WARNED!

I AM NOT TO BE HELD RESPONSIBLE IF U DAMAGE UR PHONE / SPILL UR COFFEE / MISS UR ALARMS / ANY OTHER CALAMITY/MISHAP

so besides all the great things hes givin us he always warnes uss ;)
[Sony Xperia S, Acro S, Ion] poo-tang:
Thanks I can't read. :rolleyes:

BTW my findings are with stock values no overclocking. If you was directing that at me. Processers will heat up even on a stock out of the box device. Sadly no fans or liquid cooling for phones yet.
[Sony Xperia S, Acro S, Ion] DooMLoRD:
hehehe.... reminds me of those record breaking benchmark desktop rigs :D

dunno how it was sent as qoute on you post...

:D know you can read...lol
[Sony Xperia S, Acro S, Ion] sessel:
Hy, #9007 all seem good with 2 days of test but this morning.Deep sleep go away need a reboot and with navigation maps apk in screen off i've deadsleep issue.

Rom : ultimate experience

Cpu : interactive 192/1512 cfq

Dalvik wipe wipe during the install.

Before this nothing to report battery life is very very nice.
[Sony Xperia S, Acro S, Ion] K900:
There can be no data corruption with those kernels. Even if something goes wrong, you can always use fastboot to recover.
[Sony Xperia S, Acro S, Ion] poo-tang:
Update on my tests

001. No issues no reboots in games and stayed cooler

002. No issues no reboots in games

003. No issues booting and running but have had a couple reboots 15mins into heavy games.

004. About to start testing
[Sony Xperia S, Acro S, Ion] DooMLoRD:
added another test kernel #9008 with only OC to 1890Mhz without any cpu feq fixes... its a derivative of the problematic #9003

please test it out...

[Sony Xperia S, Acro S, Ion] DooMLoRD:
dont worry we will have a VERY stable kernel, just like all my other kernels... its just that we need to find the culprit code which is causing the issue... i never include unstable code/un-necessary patches in my kernels... but sometimes some bad code comes in... so i need all willing testers to help test out the test kernels...
[Sony Xperia S, Acro S, Ion] sminki:
Yup, same here, all week on 9007.

On 9008 as of now
[Sony Xperia S, Acro S, Ion] marcjuh:
Been flashing kernels all night....

9004... 9006..9008..

When using nothing... Apps to set the freq.... Fast... When using incredi.. The 9008 has more trouble fixing the wifi at start. Up.. Testing further...

All time settings.... Smartassv2, deadline,prefere bfq but not all have this so test all with same settings and frequency app....

Will report back.... :D

Flashed 9008 from 9006. By exrec. Fully

Working sofar. Did a antutu not for highscores but for stress test cuz asking to much will frees uo screen. Alls well.

Maby my thoughts but the fps stays at 58...while 9006. Goes through 59+

Seems to take longer with 9008 then 9006...testing that is...

Sorry to ask again but what which one,s more important running 008 as we speak with no issues so far. if that one still crashes for some is that still important to test, thanks
[Sony Xperia S, Acro S, Ion] gm007:
I just test 9009 and it's running fine,9008 freeze on scanning sd.

I think some phone doesn't accept 1.8ghz

That's why 9003 and 9008 have freezing even if the freq are locked to max 1.5ghz on boot.
[Sony Xperia S, Acro S, Ion] marcjuh:
Flashed 9009 same as previous 08

Reboot test 2/3d hit the 59+ faster..

Wifi full... Lol screen.... Less intense sharp... The other has deeper sharpness seems almost blurry lol. Maby to long looking.. But must say testing a kernel can only be useful when testing longer... Gonna try the 9008 for longer... Cuz i like the gpu oc and had no freezes..

Verstuurd van mijn LT26i met Tapatalk
[Sony Xperia S, Acro S, Ion] gm007:
On 9009 I feel the the games and transitions are more smooth and the phone heat less.

I don't thinks there is need for gpu oc.

Thanks Doom.
[Sony Xperia S, Acro S, Ion] marcjuh:
Damn didn't set it in max tried it with 1728... Ginne try now with maxout the 08

... Will be back

Edit... 18900 2/3d in test doesn't make a difference?.. Its pure the cpu thats faster... All seems nit so nippi at maxout..

17280 feels better but the test did finished.... Batt. At 10 % deadline on demand..... Kernel08...

Verstuurd van mijn LT26i met Tapatalk
[Sony Xperia S, Acro S, Ion] DooMLoRD:
well the refresh rate on this device is locked at 60Hz for both 2D & 3D... so even if the hardware is very much capable of pushing 60fps+ u will always see some benchmarks getting capped at max 60fps...

better way to test is to play graphics heavy games where u get 25-30 fps on stock kernel and then test GPU oc kernel to see if it really makes any difference...

#9008 is highest priority as the "boot loop at OS booting" issue is now identified to be related to 1890Mhz OC kernel... i just need a few more confirmations...

yes you are right... check the above comment...

if i remember correctly some users reported that some games were crashing after 10-15 minutes of usage & while watching videos... so i want to check if its related to GPU OC... hence i have released a test kernel which has no GPU OC to check where the problem lies...

check my comment/reply in the beginning of this post...

@ALL

so guys i have got multiple confirmations that the yellow tint issues are arising because of device heating up above 40 degrees...

also some users are facing issue with CPU being overclocked to 1890Mhz...

in light of the above, this is what i am planning, i will keep the future releases with only a slight CPU OC 1728Mhz and may even remove GPU overclock because we dont want that nasty yellow tint showing up ;)

OR

if users want i can keep two versions:

1) all other features + CPU OC to 1728Mhz + NO GPU OC (stock 266 Mhz)

2) all other features + CPU OC to 1890Mhz + GPU OC to 320 Mhz

i wont be able to keep other permutations and combinations though :p

what you guys think?

let me know in the general discussion thread...

also we still need to find whats causing the dead sleep issue "device is found in powered off state"... so please keep testing the test kernel and let me know which one cause the dead sleep issue...
[Sony Xperia S, Acro S, Ion] K900:
Deep sleep is caused by too much undervolting that some devices can't handle. You probably want to make two kernels: one with 1.7Ghz and less undervolting and one with current settings.
[Sony Xperia S, Acro S, Ion] drigerott:
DooM can i ask you if we can have SIO scheduler in next release?

Thank you very much
[Sony Xperia S, Acro S, Ion] DooMLoRD:
the kernels is not undervolted by default...

lets see... may be later...

Would love to keep the gpu OC ass well :D

Not playing that much games.

Am testing the 9008 did not used it today batt. Seems to be doing great but with cpuspy i see deepsleep is barely used while the 348 is almost all the time on :what:....

[Sony Xperia S, Acro S, Ion] drigerott:
9009 works nice .. (for me no prob even with 03a)

anyway with p990 and gpu oc there was a gain in fps of about 1fps...not really much... but battery was really worse ...

i can confirm that no gpu oc on xperia s is the same.. 1/2 fps gain in 50% of games... not that much..

so you can leave gpu oc for me ;-) o like you said.. 2 version 1 with oc and 1 without oc
[Sony Xperia S, Acro S, Ion] Apology11:
Can somebody explain whar the "dead sleep issue" is, because I tested :

v01a: worked fine

v03: reboot after some time (in certain apps like youtube)

v03a: same as v03

#9007: no graphic output after standby and alarm (had that issue only one time)

#9009: works fine so far

So I didn´t have the dead sleep yet but what exactly is it?

Forgot to mention that smartassv2 works for me sometimes but sometimes not .... after I cleaned Dalvik Cache with Titanium Backup it worked on #9007

Hy, #9008 test since you post it.

One reboot after the install.And after nothing to tell.

I test with interactive and smartass with cfq and noop (192/1890 all the time).

No problem with look screen, is better to answer when people call me, before i need to swipe 2 or 3 times and no deadsleep for the moment.

Battery life is better, before phone eat more with cpu 192/1512.

Continue the test a little time and after look #9009.

and the device restart continual ..

and this happen when i install a kernal v2+

Specifically the overclock kernal ,,

i have tryed , to install it on other firmewire , and a custom rom ,,even i flash an original stock firmewire with stock kernal , and start over ,

but evey time have the same proplem

stock advance kernal work fine , and doom kernal v1 work fine to..

9002 - Used for 2 days, no issues found with the above tests, 41deg max and Stable.

9003 - Stability test report shows ~6mins @ 36 degrees it rebooted. Unstable.

9004 - Used for over 3 hrs with ondemand/BFQ IO set, no issues found with the above tests, 40 deg stable.

9005 - Used for over 3 hrs, no issues found with the above tests, 40 deg stable.

9006 - Used for over 3 hrs, no issues found with the above tests, 40 deg stable.

9007 - Used for over 3 hrs, no issues found with the above tests, 41 deg stable.

9008 - Spin off for 9003, stability test report shows ~1min @38deg it rebooted. Unstable.

9009 - Used for 2 days, no issues found with the above tests. 41 deg stable.

I was able to break the phone with 9003 and 9008 easily with out even overclocking and I always ran stability test first.

No bootloops experienced.

Doomlord can you make a kernel with all the above commits with out these two (9003) offenders for testing? I'm back to using 9002 happily so i don't believe the gpu overclock is having an effect on stability, definitely not for me.

Free Stability Test app in market if any1 wants to try:

After a while of testing with 9002 vs v1a vs 9009, 9009 offer the best stability without producing unnecessary heat and worse battery life. To me, GPU oc is really not a good option compares to performance vs battery life in return. Perhaps you can release a kernel with all the above optimization without oc of cpu and gpu? For testing purposes
[Sony Xperia S, Acro S, Ion] DooMLoRD:
thanks for the detailed & consolidated report!

its clear that some devices are having issue with the 1890 Mhz OC kernel... so from next release i will be removing it...

yes as i posted a few pages back i am considering maintaining two versions of the kernel:

1) Normal - all latest features + max CPU OC 1728 Mhz + NO GPU OC

2) Performance - all latest features + max CPU OC 1728 Mhz + max GPU OC 300Mhz

OR

Performance - all latest features + max CPU OC 1890 Mhz + max GPU OC 300Mhz

@ALL

if anyone has video playback shutter/lag issues please report in details ur current setup (ROM version/kernel version/CPU gov./IO Sched/CPU min,max freq)
