[Sony Xperia P, U, Sola, Go] OmarBizreh:
Thank you my friend :D

By the way about the Google Chrome issue I had the same issue, but after Google released the last version of Chrome that issue is gone.

As for v2 the only reason why you are not having signal loss is v2 doesn't include governors, the brains rom users are facing issues when using pegasusq governor with the brains rom because the brains ROM includes the same governors but tweaked for Xperia U.

if you go into /system/etc/init.d/ you will find a modules folder. Since you can't afford losing your signal I will not push you to update to the latest version but as for me I didn't face signal lose on Stock ICS. and the brains rom users (or most of them) are reporting that the issue is gone after removing the modules folder. Or by using onDemand governor which you are using right now.

@icerebro: here is the new download link: Sliding_XP - Google Docs Link
[Sony Xperia P, U, Sola, Go] MajestyZ:
Thank you for your reply.

Been there, done that, haha. I even installed the "fix" which was included with the Brainsrom, to no avail. I still had signal loss. Even after removing the modules folder.

So I'm sticking with V2 for the moment, if you don't mind. I'll join you again on V7.

About Chrome: I'm not sure if it's only Chrome related. I can remember that whenever the new official update from Sony came out, the problem was gone. And as I'm sure I'm using the latest Chrome version right now, and I still have the problem (didn't have it with your Test 5 and Test 6), it must be kernel related too, right?
[Sony Xperia P, U, Sola, Go] OmarBizreh:
To be honest I don't know if it's kernel related or software related, because when I faced this issue the only fix for it was updating Google Chrome.

As for the kernel I'm thinking of releasing two copies tomorrow, one with the governors I included and one with the default governors. I hope by doing this users will stop having signal issues, it's really annoying to be relying on the phone and then finding out it has no signal :-/

Anyone has test the v6 test 8 version???
[Sony Xperia P, U, Sola, Go] kudaj316:
Wtf is going on here... New kernel again., really deep? Wow, xperia p is getting better and better, btw, whats the use of power module deep? Is it necessary?
[Sony Xperia P, U, Sola, Go] mlm1102003:
flash using fast boot :

fastboot flash boot TEST8.img

replace TEST8 with kernel name

Clearing Cache and Dalvik-Cache recommended

Sliding_XP-v6-TEST-8 - Power Module

Power Module will not work on previous versions, I didn't enable it's option in previous versions. Don't attempt to install it unless you are using the latest test version !!

To Flash Supplied Module, Download Android Terminal

Put the downloaded module on the root directory of your phone, type the following in Android Terminal:

1. su (to gain Superuser rights)

2. insmod m1.ko

can you add "Two Way Call Recorder" support ?
[Sony Xperia P, U, Sola, Go] Hefko:
This night I had signal lost. I'm using your latest kernel and stock ICS rom 6.1.1.B.1.54. Any help?

EDIT: I am using only 2G

Sent from Xperia P
[Sony Xperia P, U, Sola, Go] chewdaniel:
yes. use ondemand governor
[Sony Xperia P, U, Sola, Go] mlm1102003:
can you add two wat call record support to this kernel ?
[Sony Xperia P, U, Sola, Go] Xperia_Fans:
Wow thanks you very much :D
[Sony Xperia P, U, Sola, Go] Xperia_Fans:

TEST 8 i had 1 signal lost today too, right now i am using cfq I/O because it seems that i have signal losts when i use sio, we will see today
[Sony Xperia P, U, Sola, Go] kudaj316:
I think signal loss is network issue,not kernel, coz i really dont hv this issue,on any of the versions
[Sony Xperia P, U, Sola, Go] MajestyZ:
Most likely because you are not using the Brainsrom, right?
[Sony Xperia P, U, Sola, Go] kudaj316:
nope,i was using brainsrom til v6test-5, but still no signal loss...even deep was wondering,
[Sony Xperia P, U, Sola, Go] neverhood11:
Not any issues so far... Quadrant score: 29xx, battery still 94% since yesterday... Amazing work Deep! ;)

I`ve been using SmartassV2 governor with Sio scheduller last days...seems to be good :) No reboots or signal loss anymore...
[Sony Xperia P, U, Sola, Go] [Fenix]:
just flashed version 6 test 8 following the chewdaniel's guide and all went well ... thank him for the guide and deep for all his work :good: ... you are amazing guys :D
[Sony Xperia P, U, Sola, Go] dinoCRO:
When I type adb push m1.ko /system/lib/modules I get error: device not found? What's the problem?
[Sony Xperia P, U, Sola, Go] OmarBizreh:
I have come up with a conclusion, All users of the Brains rom I will release for them another copy that doesn't include governors since they are the reason behind the signal loss. IO schedulers will be included but no extra governors.

I will also keep another copy for those who are not having issues while using governors.

It will take some time for me to do this but that's the best thing I found :)

Did you enable USB Debugging in your device?

To do so: Settings -> Developer Options -> USB Debugging (it's the first option over there)
[Sony Xperia P, U, Sola, Go] dinoCRO:
Yes of course. I connected the phone in the fastboot mode. Is that how it should be or it must be turned on?
[Sony Xperia P, U, Sola, Go] mlm1102003:
i use Fidelity VX 7.0+ - Stable fidelity experiences rom

with this kernel

it randomly get reset(i think it's sth about messaging)
[Sony Xperia P, U, Sola, Go] OmarBizreh:
To use Adb your phone must be turned on and USB Debugging is turned on. :)
[Sony Xperia P, U, Sola, Go] OmarBizreh:
sth?

And which governors / IO Scheduler you use?
[Sony Xperia P, U, Sola, Go] dinoCRO:
It worked.Thx
[Sony Xperia P, U, Sola, Go] mlm1102003:
i don't that ,how to know which governors i use ?or how to change ?
[Sony Xperia P, U, Sola, Go] chewdaniel:
there are a few things you can use... SetCPU, Antutu CPU Master, a few more. I personally use No-Frills CPU Control. it does the job well :)
[Sony Xperia P, U, Sola, Go] mlm1102003:
governor : pegasusq

i/o Scheduler :deadline

and which governors do you suggest?
[Sony Xperia P, U, Sola, Go] chewdaniel:
play around to see which is the best settings for u. for example... Deep uses PegasusQ/SIO wthout any issues but PegasusQ/Hotplug gives me network drops (please don't tell me about Brains rom i'm not using it) so i am using OnDemand/SIO... generally try to use the SIO or NOOP scheduler as they are the best for performance and stability...
[Sony Xperia P, U, Sola, Go] huseinn:
just curious what Power Modules do in the latest version... but wont stop downloading now :P and try to figure out hehehe
[Sony Xperia P, U, Sola, Go] Jamal_RS:
I don't know why for me, battery life and performance is worse than before flashing test8

In this vrsn each 2 min battery lost 1%,

Quadrant score is about 2400

I come back to test 2
[Sony Xperia P, U, Sola, Go] AceDuff93:
Well, it looks like my phone, when it's time for benchmarks, perfectly fits only with Ondemand + Sio, cause it's the only couple that makes me score around 2700 point on Quadrant. I tryed many other combinations but can't get over 2200-2400 points (even using Performance or Smartassv2, which are supposed to get better score than Ondemand)...

What's strange is the fact that if I use different governors-I/O during my routine I do see some differences between them: for example, Ondemand + Sio is a quite balanced solution, whereas if I set Performance + Vr the phone looks more resposive, almost absolutely lagfree, etc (though it works anyway very well with Ondemand + Sio).

Bah, these benchmarks apps...Who knows what they do...:p
[Sony Xperia P, U, Sola, Go] nickholtus:
benchmarks doesn't say much.

2 weeks ago i did 3 benchmarks with a score arround 2900 and a day later i did 3 with arround 2700 score

seems my edge is broken ,shows connected but cant connect in fact,i still can call, gsm is all right

this time i use smartassv2/sio

p.s smartasv2 battery is good.:)
[Sony Xperia P, U, Sola, Go] chewdaniel:
is your phone turned on and usb debugging on?
[Sony Xperia P, U, Sola, Go] chewdaniel:
hmm... 5% over a period of 12 hours... of which 9 was when i was sleeping... 2 phone calls ~1 minute each, 5 minutes on FB, alarm rang and snoozed 4 times... mobile data was on the whole time...

pretty good :D
[Sony Xperia P, U, Sola, Go] Xperia_Fans:
Yes USB debugging mod is on and the phone is turning on but when i type adb push m1.ko /system/lib/modules inside the fastboot cmd there are displaying error:device not found i have try several time but this issue still there...
[Sony Xperia P, U, Sola, Go] OmarBizreh:
So all your issues came when you had Pegasusq right?

in this case I will make two copies one with and one without pegasusq :)
[Sony Xperia P, U, Sola, Go] OmarBizreh:
Download these Flashtool drivers: Drivers

when installing make sure to check your device drivers and the last two options (if I'm not mistaken those are Fastboot and Adb drivers) then try again :)
[Sony Xperia P, U, Sola, Go] Xperia_Fans:
Thanks for let me know Deep :) I will try it now :D
[Sony Xperia P, U, Sola, Go] AceDuff93:
Yeah I know, indeed I don't pay much attention to them, I use them just to see how much the phone scores, but that's all...;)
[Sony Xperia P, U, Sola, Go] stole38:
what governor are you using ? cause i got the usual SlidingXP drains ... i lost over 15 % from sleeping from last night , but im not using the power module :/
[Sony Xperia P, U, Sola, Go] neverhood11:
You cannot loose 15% over night...something`s wrong man.. I loose 1%, max. 2% every night..

[Sony Xperia P, U, Sola, Go] neverhood11:
My phone wasn`t on a table :) Actually I didn`t sleep a lot last night...was out in the clubs, calling, texting, data on some time...

I don`t use any battery "tweaks".. Just clean BrainsROM, SlidingXP latest, screen brightness on 0, SmartassV2 + Sio...
[Sony Xperia P, U, Sola, Go] huseinn:
then, the key maybe on Brightness and Smartassv2, will try it.., haha, uh, for tweaks, I used V6 Supercharger and KickAss kernelizer, maybe I'll

try to delete the Kickass, or just wait deep to explain..,

I'm going to add now the two IO Schedulers that I told you about yesterday (ROW & ZEN)

and release two copies one with default governors and one with the extra governors, those who have issues use the one without the extra governors as I did all that I can to try to fix governors issue, but I'm no C Programming Expert, I can't play with those governors and I didn't find a patch for Xperia P :(

That's all I can do guys for fixing signal loss issue :)

After installing new version of kernel do we have to install the power module again?

Deep, so what are these two new schedulers? Row and Zen? Can you tell more about them?

Thank you :)
[Sony Xperia P, U, Sola, Go] OmarBizreh:
Have you installed adb drivers? go back a page or two in this thread, and you will find the link for the drivers in one my comments.

Be sure to select the last two options as they are for Fastboot and Adb :)
[Sony Xperia P, U, Sola, Go] OmarBizreh:
The ROW scheduling algorithm will be used in mobile devices as default

+block layer IO scheduling algorithm. ROW stands for "READ Over WRITE"

+which is the main requests dispatch policy of this algorithm.

+

+The ROW IO scheduler was developed with the mobile devices needs in

+mind. In mobile devices we favor user experience upon everything else,

+thus we want to give READ IO requests as much priority as possible.

+The main idea of the ROW scheduling policy is:

+If there are READ requests in pipe - dispatch them but don't starve

+the WRITE requests too much.

About Zen IO Scheduler (It might not be compatible with Xperia P, but giving it a shot wont harm :) )

It's an FCFS (First come, first serve) based algorithm. It's not strictly FIFO (First in First Out). It does not do any sorting. It uses deadlines for fairness, and treats synchronous requests with priority over asynchronous ones. Other than that, pretty much the same as no-op.

Zen IO Scheduler is used here: http://xdaforums.com/showthread.php?t=1958143

[Sony Xperia P, U, Sola, Go] OmarBizreh:
It's better if you do so, those modules are made explicitly for Xperia U , after I tested them on my phone (before it got bricked) the phone started acting strange. If you are not finding issues while keeping them, then there is no need to remove them :)
[Sony Xperia P, U, Sola, Go] Gaurav8180:
hi deep!! i just flashed v6 final w/o governors, but in setcpu it still shows that i have six governors (ondemand,perf,smartassv2,userspace, conservative, powersave). so does v6 with governors has more governors than w/o one??? i mean more than 6.:confused:

and does v6 w/o governors has that two more schedulers also??? that zen and dont remember:confused:??? because they don't show up in the list in setcpu???:silly::confused:
[Sony Xperia P, U, Sola, Go] BeDesireS:
Flashed the final V6 and power modules are still working.

Let`s see how the final version goes.

I had no probs with Test 8 and battery life was really good!

Thanks for your hard work Deep! :good:
[Sony Xperia P, U, Sola, Go] arnes_king:
I am using now v6 final w/o governors on thebrainsrom 3 (with deleted modules folder) and till yet i didn't had any problems, no signal losts or reboots.

I am using smartassv2 with sio scheduler, the battery is after about 24 H at 48%
[Sony Xperia P, U, Sola, Go] chewdaniel:
yo Deep i noticed u put the entire Test8 under old releases including the Power Module. does that mean that it's not needed anymore in the final v6?
[Sony Xperia P, U, Sola, Go] zaji06:
Iam flash v6 final and I got BOOTLOP ..........
[Sony Xperia P, U, Sola, Go] megablakbar:
How did you flash and what rom do you use?
[Sony Xperia P, U, Sola, Go] Gaurav8180:
i used v6 final w/o governors for almost 3 hours and unfortunately i hardly got any signal strength, it was very much fluctuating and i didn't able to call even a single one properly. calls were disconnected after 5-10 seconds. it might not be a kernel problem but i did not experience it in any of the kernel version.

For further scrutinizing this network problem, 30 min before i flashed v6 test 7(26/12), talked to my friend:p and didn't get any call disconnection. network strength also seems pretty decent. So eventually i can relate this problem with the v6 final w/o governors but still i might be wrong.:silly:

please do something deep:(:
[Sony Xperia P, U, Sola, Go] OmarBizreh:
By the way guys, version 6 final is the same as version 6 test 8. the only difference is the final version has two copies one with extra governors and one with default governors.

You just got me more confused now. on version 6 test 8 feedback's were good, but now they are not :S

So please try clearing caches and dalvik-cache. try out other governors or IO schedulers. The only reason why I'm asking for this is I don't have the device any more to test, or else I would've made tests before releasing this kernel. I know it's not nice to have a kernel that gives issues from time to time. So please if someone can try what I said earlier I would really appreciate so I can fix the problem even though I doubt it's from the kernel because it's the same as test 8 which no one reported issues (other than signal issues).

Note for The Brains Rom Users:

The dev of that rom contacted me today asking for more info about the signal loss issue when using his ROM and my kernel. if users of the brains rom can contact the rom dev to provide with more details about the issue that would be great :)

Maybe we can get to a solution for this issue :)

NOTE FOR NEW USERS

Please stop sending PM's about signal losses WHEN YOU ARE USING THE VERSION WITH GOVERNORS !!

I have clearly said that there will be two copies, one without governors. I also CLEARLY SAID those who are having signal issues use the copy without governors. :)

Could you flash stock kernel and report signal status?

Thx
[Sony Xperia P, U, Sola, Go] huseinn:
Just want to share, I just tried THP v6 kernel and Depp kernel (v6 test 8 +powerModule) , what I got in THP kernel is the battery drain is slower, but

only a bit, then in depp kernel the performance is better, In QUADRANT I got around 2800 with Depp's and 2400 in Thp's with same GOVERNOR

and I/O (Forgot to capture), :silly:

and I use FPS meter to measure the FPS while I play Need For Speed Most Wanted

with THP's I got 15 FPS and average of 22

with Depp's I got 29 FPS and average 28

Thats All only for Sharing purpose :o
[Sony Xperia P, U, Sola, Go] Gaurav8180:
In stock kernel i have never faced this problem unless the network problem is on operator's end.

Actually i used 3G network while using v6 final w/o Governors and got fluctuating network with random call disconnection and after 10 mins when i flashed v6 test7(26/12) the network status was better than V6 final and i talked about 40 minutes without any disconnection. Might be while i was on v6 final the network problem could be from operator's end and fortunately that would have been solved until i flashed V6 test 7. So i cannot confirm was that a kernel problem or some real network problem. :confused:

After flashing v6 test 7 the 3G network was not that strong as it was earlier, so now I am using 2G network only and its pretty good.:) I didn't try 2G network on v6 final and cannot confirm was the problem with 3G only or not. Would confirm it tomorrow, surely.

Tomorrow i would again flash the v6 final w/o Governors, to find out whether that signal strength problem was from operator's end or caused by the kernel.

hope you will understand me and would wait for my reply.:D
