I don't have the problem every time that i wake-up the scree;so it's very difficult to say what version doing the issue...
[Sony Xperia S, Acro S, Ion] Apology11:
I just had an error with v04a:

I was just watching a YouTube Video with tubemate and downloaded another, when the phone rebooted suddenly.

Gesendet von meinem LT26i
[Sony Xperia S, Acro S, Ion] zanndoth:
I re-flashed 04 again before 1 sleep last nite and left the phone charging, the problem seems to disappear. Not sure if it was the flashing issue, or the phone just needs to shut down and restart a few times.

Never had this issue with 01 or 03a.

Will try with 04a.
[Sony Xperia S, Acro S, Ion] scook94:
I'm fairly sure I had the deep sleep bug on v3, but at the time I didn't realise what it was and assumed it was the phone itself.

Also experienced it on v4, but still to see the problem on v4a

Hello,

I have a problem with wifi since the implementation of DoomKernel, wifi jumps from time to time, time between a few seconds to several minutes, then work again.

How?
[Sony Xperia S, Acro S, Ion] cihanleanne:

[Sony Xperia S, Acro S, Ion] DooMLoRD:
the main kernels in v04 and v04a are same...

BTW i grabbed this dmesg after i encountered the "screen off, unable to wake" issue:

Do you know the charging current that we currently have in this kernel for wall charger? I noticed that even when it's 100% and still on wall charger, and I starts to use it for video streaming with 3g, it can sometimes drop to 80% even when charger is charging it.
[Sony Xperia S, Acro S, Ion] gm007:
That is not related to the kernel,it's something in charging system and charger.maybe can be solved by using ep850 fast charger.
[Sony Xperia S, Acro S, Ion] fastcx:
Not possible to enable quick charge in our kernel like some of the devices out there?

[Sony Xperia S, Acro S, Ion] marousa_king:
will i lose my apps by flashing this?
[Sony Xperia S, Acro S, Ion] sessel:
You don't lose nothing.Make a dalvik wipe it's better after the install.

Ps: If you want ask something it's better to go to general.A thread is open to dial about Doomkernel.
[Sony Xperia S, Acro S, Ion] denaz:
i'm with v4a since you released it. No reboot and no strange behaviour at all but what i've seen is that my phone don't go in deep sleep. In aero mode i've lost more than 40% this night. And the last night too (more or less 6hr).

Hi DooMLoRD

i have a question:

will this kernel also work on the xperia p?

otherwise i need to compile it:(

[Sony Xperia S, Acro S, Ion] ChefChaudart:
Question about installation

The download contains a file called S-DooMKernel-v04a.zip.

Do I have to rename it update.zip ?

( or flash S-DooMKernel-v04a.zip ?)

Not necessarily.

select install zip from sd card, select doomkernel x.zip

[Sony Xperia S, Acro S, Ion] DooMLoRD:
nick, all Xperia 2011 had the SAME chipset (Snapdragon S2 MSM8255) but the kernels of one device DIDNT WORK ON OTHER DEVICE...

now Xperia S is Snapdragon S3 (MSM8660) while the Xperia P is ST-E NovaThor, so tell me how will the kernel for XPeria S work on Xperia P :P

;)

FYI sources for Xperia U/Sola/P are not available
[Sony Xperia S, Acro S, Ion] tsukeyomi:
Hi dude, i see your work is being really appreciated.

Actually, i'm pretty new to the Android world, and i'm planning to buy an Xperia S very soon.

I have studied a bit of Android and its stratification approach. I know the kernel (the bottom layer) mainly handles the hardware component's drivers and power management.

Now, seen with the eyes of an actual developer, what are the differences between kernels? I mean, it's just a matter of optimization or there's more behind?

To answer my question more clearly you could compare the "stock" Xperia S's kernel with the one you developed, pointing out functionalities and differences between the two could help me understanding.

I want to start learning about Android more in depth, as i'm planning to start developing apps too, in the future; so far i really, really like Android and what's around this platform.

Thanks a lot for your time and sorry for the nooby question.

P.S. I was born in India too ;) It really makes me happy to see there's so many talented people from my country :)
[Sony Xperia S, Acro S, Ion] DooMLoRD:
Ok I have some good news.... Been using the v04/v04a kernel for more than a week now,in the first two days had the "dead sleep"/"screen stuck in lock mode" bugs but after that haven't had any such issues... I hope you guys are also not facing any of these issues now...
[Sony Xperia S, Acro S, Ion] poo-tang:
Not had any reboot issues so far on 4a works nice. Not sure about others but do have points at which the device starts to lag like i have turned max clock down to values of what min should be, but can sort that out with a reboot. Just wish the gpu overclocking was not to blame for reboots as did work nice apart from that big issue.
[Sony Xperia S, Acro S, Ion] sessel:
And for me after test v01a.

I reinstall v04 with a clean install on stock rom and install KAv5.2 and no issue, nothing...

[Sony Xperia S, Acro S, Ion] a4rocks:
It still happens to me quite frequently. Though sometimes one way used to work something like pressing the power off button and then the Home button constantly and the screen would become awake. But this works only a few times and most of the times, hard reboot is the only way

hi, I'm new to this " business kernel ", is this kernel more recomended than the standard one? I've read this article but I didn't understand much. If I'm corect if I install this kernel my CPU speed will increase to 1800 mhz?
[Sony Xperia S, Acro S, Ion] K900:
Don't install this. First learn what it does, then install, not the other way around.
[Sony Xperia S, Acro S, Ion] sminki:
Wise words sir.
[Sony Xperia S, Acro S, Ion] SilentEYE:
I created a patch zip file with an app called Pdroid, which can handle App permissions.

If i go into recovery the installation aborts, because the aroma installer is starting. I know that without the Aroma installer, it would work perfectly.

I dont want this tool.
[Sony Xperia S, Acro S, Ion] DooMLoRD:
Ok sorry for the late reply...

So specifically between my kernel and stock kernel sources... I have built my kernel using the stock sources as base... If I want to add any particular functionality/feature from higher version kernels or kernel sources of different device/kernels then I look at the underlying code and port it to my kernel sources... 99% of the times this is not a direct cut-copy-paste operation as many functions used internally are different and they have to be modified to suit our base kernel version... Many a times the patches used for these additional functionalities are not independent, meaning that there can be numerous conflicts in code... So one has to manually sit and go thru code to see which sections are problematic and see if it compiles... This is just one aspect... Even if it compiles, intensive testing needs to be done to verify that the new updates/patches are not conflicting with other functions/features... If there is a conflict then begins bughunting and fixing stage... Finally when everything is sorted users get a new kernel to play with ;-)

As for specific changes in my kernel as compared to stock kernel check my github repos

i also have an Arc, i would think its about the same.

But problem is that there are many times which my other devices can detect a wifi network but the XS cant. Like im in office now using my office wifi, but i cant detect my office wifi on the XS.

so i tried hotspot on my laptop, and the XS still cant detect the hotspot although it is next to me now.

Not sure if this has been reported or not. I'm running on 4a and some time when I play videos, the player will crash. The funny thing is, the audio will still continue to play. Even if I try to open another video. Which results in the 1st audio and the 2nd audio can be heard concurrently. Closing the program or forcing the vidoe player to close doesnt fix the problem. The only way to get rid of it is to restart the phone.

Tried different players and even video format. But it still happens occasionally. Had no problem when I switch to advanced kernel.

Will try with different kernel when I have time.

Use ondemand, I have no problem with lagging or issue with gaming on that.

EDIT: smartassv2 is longer relevant in our current gen of soc, with deepsleep, smartassv2 screen off max clock will only bring issue. If you wanna have similar performance with ondemand, you still can tweak init.d script to tune ondemand up_threshold, sampling_rate, & even sampling_down_factor to be more responsive or battery saving.
