Hi guys, I'm an Xperia P owner. I flashed this kernel about two weeks ago, and this was my first custom kernel.

I really want to thank you, Deep, because the work you did is really good. Up to now, I had no problems in particular, just a couple freezes with Facebook app (which anyway, considering what app we are talking about, I can't really link to your kernel), and a freeze some days ago. I honestly don't remember what I was doing, but there ware many apps running, etc. Nothing bad. ;)

As for the signal drop question, I can't really give you a precise feedback: as you suggested, I used pegasusq/sio for the first days, but I didn't face any particular issue. Or, better, actually when I woke up the phone, I saw sometimes signal was absent (I mean, none of the four notches (?) was there, but still I didn't have no signal at all - there wasn't the red cross), but after two or three seconds signal was back again (I was in areas where there usually is full phone reception). So I don't know if this is an issue related to the kernel or else. Anyway, I was never forced to reboot, as, if I understood it right, those who have this issue.

Anyway, I wanted to try different configurations, so now I'm using ondemand/sio and I have to say battery drain is slower than stock kernel (with pegasusq/sio too, and maybe it was even a bit better), especially while the phone is in stand-by. Now I can finally leave Wi-Fi turned on while I'm at home and receive push notifications without being obessioned with battery drain, thank to you! ;)
[Sony Xperia P, U, Sola, Go] OmarBizreh:
WOW, that is one great feedback :D

Thank you for reporting my friend. As for governors (Pegasusq) I found out that users who are reporting this issue are using the Brains Rom which has a modules folder inside: /system/etc/init.d/

if you are using that rom, remove modules folder, honestly I didn't have this issue and pegasusq was my default governor ...

You should experiance better performance once the latest source code is released from Sony but for now we have to stick with this one since you don't have other choice ...

Thanks again for your feedback, much appreciated :)
[Sony Xperia P, U, Sola, Go] clijiac:
thank you deep.

i`m using the brains room ,i will delete the folder to see what happen
[Sony Xperia P, U, Sola, Go] nwayen:
Just a quick note, deleting the "modules" folder within etc/init.d seems to fix the bug that WiFi stayed on in "extended stand-by" mode. I'll test some more to see whether this is really the case, that would make this kernel near perfect :)
[Sony Xperia P, U, Sola, Go] AceDuff93:
I've been following the thread since its birth, so I saw more or less everything that was written...;) Indeed when I saw your suggestion I checked that folder, even though I'm using stock rom (.54), but there was nothing inside...;)

By the way, you remembered me about a question I wanted to ask you: which rom would you suggest to go with your kernel? And which one are you using now? Thank in advance for your reply! ;)

P.S.: I've been using Nova Launcher Prime since many months, so I obviously set it as system app as soon as I flashed the .54 rom and this kernel. It's definitely the best mix for our P: Nova Prime + Sliding XP kernel rock! :good:
[Sony Xperia P, U, Sola, Go] OmarBizreh:
To be honest my friend, I lost my device because of this kernel, while I was testing version 5 and after I have upgraded to 6.1.1.B.1.54 the device turned off and never turned back on, BUT at that time version 5 had overclocking, I removed it after it bricked my device.

I was having stock rom installed, no build.prop values added nor init.d scripts running, everything was pure stock except for the kernel. and I have removed some Sony apps that I don't use like Japanese keyboard.

But most users here are using Brains Rom if I'm not mistaken, so I guess you should try it out.
[Sony Xperia P, U, Sola, Go] neverhood11:
Been using Smartass since yesterday...seems to be good so far ;) Not any issues, battery performance is good..
[Sony Xperia P, U, Sola, Go] AceDuff93:
You're right Deep, forgive me, I completely forgot that you bricked your P...What an idiot I am, escuse me...:(

Aaaah, my memory always makes me make bad impressions...-.-"
[Sony Xperia P, U, Sola, Go] OmarBizreh:
It's ok my friend, at least others are making benefit of this thing :D the only thing that makes me need a device is to continue with Droid Manager, as for this kernel, many users are helping me in testing before I release to public, and that is more than enough to me :)

If you have any suggestions lay them on this thread :D
[Sony Xperia P, U, Sola, Go] Lauri455:
I'm quite sure that a simple 2D tetris game shouldn't eat so much battery...

Colors are different for some reason, screencap app's fault.

Running v6 test 6, ondemand / sio; max 1 GHz / min 200 MHz.

What do?
[Sony Xperia P, U, Sola, Go] Jamal_RS:
Hi deep

In setcpu I set min freq to 200 Mhz and max to 800 for every governor and I/O scheduler

But after phone rebooting, the max value set to 1000 automatically

That's normal?

If no please guide

A Request:

Would you please in later release, change cpu frequency table to these values:

200,300,400,500,600,700,800,900,1000

Thanks man

Donated - merry Christmas :)
[Sony Xperia P, U, Sola, Go] Gaurav8180:
Hi all sliding xp users, i think we all should donate some amount for our industrious dev. It's a festival season now, so we all should donate for our dev.

Give our dev something SPECIAL on THIS CHRISTMAS. . This is my request to all.

Please do donate.

EVERY SINGLE DONATION IS CHERISHED. :D :D
[Sony Xperia P, U, Sola, Go] AceDuff93:
Well, I'd like to give this feedback:

Ondemand/sio

SetCPU profile for screen off, with range 200 - 800Mhz

everything turned off (no wi-fi, no 3G, no BT, etc.)

At 1:01am, this night: battery level at 41%

At 9:34am, this morning: battery level at 39%

2% of decrease in more than 8 hours, whereas with stock kernel (and same conditions, of course) battery usually dropped 5-6% in about 8 hours. You hit the target Deep! ;) :good:

I am not a developer and just know really few thing (actually almost nothing) about Android developing, but if I were in you, now I would concentrate more on saving battery while the phone is being used. Supposing, clearly, there's anything you can do on that side, which I don't know. But if you can, you should do it, because I'm sure that with your ability you would reach great results, which would be very appreciated by all P users, considering the small battery our phone has. Just a small hint, thank you anyway for your work, awesome done! ;)
[Sony Xperia P, U, Sola, Go] arnes_king:
Hey everyone,

i am using this kernel now since a few versions and i think that it is the best one out there :D but i have a few problems ....

First it didn't happened at all, then it started to happen sometimes and now it happens more and more often :/

The problem is that the phone suddenly becomes very very laggy, first i didn't knew why but today when i opened "CPU Master" i saw that the CPU frequency was at the min value = 200 MHz and it wouldn't get any higher by itself, so i set the min frequency to 1000 MHz and it got up, but after a while it came back again to 200 MHz, also when i set the I/O to sio it resets itself again to cfq after i reboot the phone.....

I can't seem to find any sollution to the problem other then rebooting my phone which solves it until it happens again :/

I didn't installed any apps or something that might cause the problems, i am using TheBrainsROM v 03 with SlidingXPKernel v6 test 5 (i might flash today test 6 to see if it will be the same)

Also sometimes but this happens rarely the phone reboots itselfe.

Other then that this kernel is perfect, everything is very smooth, perfect performance, 2850+ results in quadrant (earlier i had just about 2200) and battery life is perfect, on idle when i go to sleep the battery doesn't drain even 1% now for me for the whole night :D If i left it at 55% it will be the same in the morning or eventually 1% lower
[Sony Xperia P, U, Sola, Go] neverhood11:
Man, I have EXACTLY the same issues :) Or I had...seems to be good now, no reboots, no lags.. I deleted modules from init.d (/etc/init.d/modules). Somebody wrote that should help and I think that really did. Now I use Pegasusq with Sio and everything seems to be OK so far.. Try it..
[Sony Xperia P, U, Sola, Go] BeDesireS:
That`s right! We should help Deep to get a new device as soon as possible!

Donated! :D

Merry Christmas to you all!
[Sony Xperia P, U, Sola, Go] josie87:
Hope we can get enough to at least help him, but if everybody who uses the kernel just donates a little bit it might be enough. Let's hope.
[Sony Xperia P, U, Sola, Go] arnes_king:
Thank you, i have deleted the modules and i also flashed version 6 test 6, until now everything is perfect and i hope that it will stay so :)

P.S. i am waiting for paypal to make my money available because now it is on "Pending" and after it is available i will donate to the maker of this kernel too :)
[Sony Xperia P, U, Sola, Go] OmarBizreh:
if you have Force 2D GPU Rendering then this could be the reason because all images are rendered on the GPU and not by software and this would use extra power for the GPU.

You should check the option in in SetCpu to set settings on boot (in the main screen of SetCPU look at the bottom you will find that option)

As for frequencies I will not touch them no more, I lost my device because of having higher frequency, true low freqs wont effect but miss functionality could happen since no one knows the amount of voltage needed for each frequency and playing with voltage values WILL BRICK the device :-/

Thanks a lot bro I really appreciate it :) Merry Christmas to you too my friend :)

Thanks a lot bro it means a lot to me :) Merry Christmas :)

Good point my friend, I will take a look on the settings and see what I can disable to make battery draining less ^__^
[Sony Xperia P, U, Sola, Go] OmarBizreh:
ALL USERS OF THE BRAINS ROM:

Please remove the folder: Modules found at: /system/etc/init.d/

this is causing many issues including signal drops from time to time. I will be contacting the rom dev asking him to put a notice for my kernel users so they remove that folder after they flash his rom.
[Sony Xperia P, U, Sola, Go] OmarBizreh:
Merry Christmas everyone and Happy new Year :D
[Sony Xperia P, U, Sola, Go] doctor_droid:
Wish u too merry Christmas and a happy new year :)

help

my phone ver is .54 and i have installed cw and rooted but bootloader is locked (i don't know about this much i come from samsung devices to sony) can i flash this kernel /??
[Sony Xperia P, U, Sola, Go] megablakbar:
No, You need to unlock your bootloader
[Sony Xperia P, U, Sola, Go] MajestyZ:
I've started to use your kernel in combination with the brainsrom kernel since yesterday. You seem like a great developer man, very active, helping and kind to your "users". Thank you for that!

I'll be sure to check out this thread every day for any updates.

I removed the modules folder, as you suggested. But, I have Test 6 installed as I was getting signal drops. Should I install Test 5 again now?
[Sony Xperia P, U, Sola, Go] xaver54645:
I'm using Kernel V4-A and TheBrainsRom V4, deleted the folder but still losing signal. :confused:
[Sony Xperia P, U, Sola, Go] doctor_droid:
I always keep an eye on ur thread bt never post as I dun want to spam this thread.... ( I do spam some others ;) )

M fine

How are u? I see alot of happy people here

Ur kernel is just superb as per the feedbacks :)

Great going...
[Sony Xperia P, U, Sola, Go] arnes_king:
After deleting the modules folder and flashing version 6 test 6 everything seems to be now without problems :)

Really the best kernel, keep up the good work, i will donate as soon as i get my money :D

Just a question, i was on version 6 test 5 and today i flashed version 6 test 6 in fastboot and it flashed it without any problems after that i cleared the partition and dalvik cache but i saw now that when i go into the settings and about phone it says in kernel that it is version 6 TEST 5 instead of 6, is this normal or did i something did wrong ?
[Sony Xperia P, U, Sola, Go] ofr007:
YES, can confirm that after deleting modules folder, kernel works perfect.
[Sony Xperia P, U, Sola, Go] MajestyZ:
Same thing here! It shows Test 5 instead of Test 6.
[Sony Xperia P, U, Sola, Go] Xperia_Fans:
Sir do I also need to delete mine is using stock sony 6.1.1.b.1.54 rom thx.
[Sony Xperia P, U, Sola, Go] [Fenix]:
Try to flash v6 test 5 and if you have any ohther apps that sleep your cpu delet them and reboot...than using set cpu for root user set performane or ondemand and sio sheduler...i have resolve the signal problem time ago and now i'm enjoyng test 6 v5 (also the brains rom 04)...amazing work by Deep :)
[Sony Xperia P, U, Sola, Go] BeDesireS:
If you're on stock, you don't have any tweaks in the folder. So no need to delete them.

@Deep

I am now using test 6 with onDemand and sio and so far I have no problems, reboots or any issues during charging the phone! :thumbup:

I am on stock. 54 using SetCpu.

[Sony Xperia P, U, Sola, Go] mlm1102003:
how to Boot into recovery ?
[Sony Xperia P, U, Sola, Go] OmarBizreh:
Turn off the phone, turn it back on, once you see the word Sony (in other words, once the screen turns back on even if you can't see anything on the screen) start pressing volume down button (DONT PRESS AND HOLD the volume down button)

By the way people, another test release is to be out after few minutes, my internet connection is kinda dead because I'm downloading a software, once the download is done I will be uploading the test release :)
[Sony Xperia P, U, Sola, Go] BeDesireS:
Great news! :)

im the first one to try...yesss, thanks deep, battery life tweaks...just what im looking for
[Sony Xperia P, U, Sola, Go] OmarBizreh:
Waiting for your feedback my friend :D

I hope this time battery life is what users want :D
[Sony Xperia P, U, Sola, Go] Gaurav8180:
Booting my laptop to flash the new version, thanks deep. Will give you the feedback :D
[Sony Xperia P, U, Sola, Go] clijiac:
after deleted the module floader,signal never lose...

just to try the test 7

thx and merry xmas deep(though a little late)
[Sony Xperia P, U, Sola, Go] Gaurav8180:
hi deep!! i think you have removed interative governor, because it was also not in the governor's list in test 5. have you???
[Sony Xperia P, U, Sola, Go] OmarBizreh:
ok then will add it back for the final release, I guess it's 24 hours away, I'm just waiting for feedbacks :) :D

By the way what is your Quadrant score now?!
[Sony Xperia P, U, Sola, Go] OmarBizreh:
Merry Christmas to you too my friend :)
[Sony Xperia P, U, Sola, Go] arnes_king:
I have just flashed v6 test7 and did a quadrant benchmark test, the score i got is 2874 which is for now my highscore :D
[Sony Xperia P, U, Sola, Go] Gaurav8180:
got 24xx on my first benchmark but battery life seems pretty good till now, atleast better than test 5, for sure. And for performance let you know deep ASAP!!!. thank you
[Sony Xperia P, U, Sola, Go] OmarBizreh:
Great to know that :D

Try cleaning cache and dalvik-cache, but someone reported 2874, and you didn't report slow performance, so I guess Quadrant was acting crazy :p

let's hope it's quadrant craziness ^__^
[Sony Xperia P, U, Sola, Go] Xperia_Fans:
Thank you :)
[Sony Xperia P, U, Sola, Go] arnes_king:
Today it happened to me twice again that my signal was lost :/ I deleted the modules folder i flashed the new kernel but still the same like with previus versions, sometimes the phone reboots itself and sometimes i loose signal :/
[Sony Xperia P, U, Sola, Go] chewdaniel:
try with ondemand governor...
[Sony Xperia P, U, Sola, Go] raunakrajvanshi:
governor for battery?
[Sony Xperia P, U, Sola, Go] OmarBizreh:
Try clearing cache and dalvik cache :)

I used to use Pegasusq governor with SIO IO scheduler, I found it's the best for me ;)
[Sony Xperia P, U, Sola, Go] Gaurav8180:
Hi deep! Today's morning I got one signal black out. Battery backup is also not upto the mark. Right now I am having a feeling that test 2 was better than test 5 and 7 in every aspect. So flashing test 2 for now. Thank you deep for trying so hard. I really appreciate it. :D
[Sony Xperia P, U, Sola, Go] OmarBizreh:
hmmm... I will put another test version tonight. let's hope it gets solved, that battery status thing is getting on my nerves. Let's hope it can be solved by tonight. By the way did you clear caches? just to be sure :)
[Sony Xperia P, U, Sola, Go] Gaurav8180:
yes bro, cleared cache/dalvik cache twice after flashing test 7.::D
[Sony Xperia P, U, Sola, Go] BeDesireS:
I flashed v7 yesterday and till now I have no problems! Performance is great and battery is really good. Also I had no problems during charging or wake up.

I am using ondemand / sio, because with pegasusq I always have problems with every version of the kernel! But I think I will give smartass a try, in fact of battery life.

Thx for your continuous great work deep! :)

[Sony Xperia P, U, Sola, Go] MajestyZ:
Might be a stupid question, but what is "ondermand" "sio" and "pagasusq" you guys are talking about? What does it do?

Are they like CPU power plans? If anybody cares to explain to me, thanks in advance :).
[Sony Xperia P, U, Sola, Go] chewdaniel:

[Sony Xperia P, U, Sola, Go] OmarBizreh:
hmm.... Let's hope you are not using The brains rom since it's modules folder is causing those issues :P

but what about battery life? or you went back to test 2?

Great to know that :D

and how about battery life until now?! I hope it got better ^__^

Those are governors or IO schedulers, to find out more about them, check this thread: http://xdaforums.com/showpost.php?p=26965230&postcount=3 :)
[Sony Xperia P, U, Sola, Go] AceDuff93:
I'm not an expert, but in spimple words, Ondemand, Pegasusq, Conservative, Smartass, Performance, Interactive, etc are "governors". You can use one of them to have a better cpu management. The choice between them lies on your need: if you need more performance, you might choose a Performance governor for example, while if you need to save more battery, you might choose a Conservative.

As for the terms sio, cfq, vr, etc, they are I/O schedulers which help you to control input/output performance: the idea is the same as for governors. Given your need to save more battery, to have better performance or to have a balance between the two aspects, you might choose one of them.

I hope what I wrote is clear enough to you. :o

Deep, I'm really happy you tried to work even more on the saving battery side! For now, I'm not moving from test 5, as it is good for me, but as soon as you get a final release (v7 maybe?), I'll definitely flash it!

Just one question: let's suppose that I want to flash test 7. So I just flash it, go to recovery after flashing and wipe dalvik cache? Or do I need to do a full wipe on my phone and then reinstall everything I had inside?
[Sony Xperia P, U, Sola, Go] OmarBizreh:
No my friend no need for a full wipe, since kernel relies most on Dalvik-Cache, but clearing it and Cache would be better.

Full wipes are not needed when flashing a kernel :D
[Sony Xperia P, U, Sola, Go] AceDuff93:
Clearing cache makes me lose my installed apps, ami I correct? Anyway, thank you very much Deep!
[Sony Xperia P, U, Sola, Go] OmarBizreh:
Not at all, you can consider cache as temp files, apps rely on them so they don't execute the same thing over and over, while they take the result from cache. it's not a clear definition of cache but the point is APK files are found at /data/app - /data/app-private (for payed apps) and /system/app

deleting any of those directories will make you lose apps ;)
[Sony Xperia P, U, Sola, Go] arnes_king:
Thanks i didn't knew that i have to clear partition and dalvik cache after flashing a new kernel, i did it and i will post the results after a few hours of phone usage :)
[Sony Xperia P, U, Sola, Go] OmarBizreh:
clearing is not a must. but if you are facing issues, it's better to start by deleting them. if the problem is still there then it's from the kernel. :)
[Sony Xperia P, U, Sola, Go] AceDuff93:
Thanks very much Deep, now everything it's clear! The only thing that stops me from flashing kernels/roms is the fact that this usually requires a full wipe, and reinstalling all the apps I have (and most of all the games, which sometimes means more than 1Gb for app!) really annoys me...I know that I can backup everything through Titanium, but I don't like the idea of putting apps coming from a rom in another rom...I'm too meticuolus (?) on this kind of thing...:p
[Sony Xperia P, U, Sola, Go] OmarBizreh:
Same here my friend, I hate it when I have to reinstall everything even if it was only one app :p

Sony did a good thing by releasing that backup app in-case I wanted to fresh install their roms.

As for kernels it's never a must to wipe out everything. but it's recommended that you wipe cache and dalvik cache which has nothing to do with apps :D
[Sony Xperia P, U, Sola, Go] OmarBizreh:
Right now I'm compiling a test version, you should experiance better battery life and lighter kernel (a bit better performance)

I hope what is mentioned in the first line will be true, please for those whom relies on their device don't flash this test version, the changes I made for this version are new and I don't know yet the efficiency of those changes.

PLEASE ONLY EXPERIENCED USERS FLASH THIS TEST RELEASE (it's still named as Test 7)

It might not even boot.

Hi deep! You will be amazed by watching this.

Flashed test 2, and the battery was at 35% at that time.

And I am really elated to share it with you that, it(35% of battery) worked for more than 6 hours for me. This is really amazing and very fantastic.

No signal drops, no reboots, excellent performance. Just superb. :D

Thanks alot deep :D

Here are the screen shots
[Sony Xperia P, U, Sola, Go] BeDesireS:
Wow another new release! :)

Will try the new version when I am back at home. But I am very satisfied with the old v7. Battery life is great for me and performance has also improved!

Great work Deep! :thumbup:

[Sony Xperia P, U, Sola, Go] AceDuff93:
Damn, you make me want to try this new one...:-p

Anyway, I must report back that sometimes, while charging, battery number on the upper bar of the screen doesn't update, though the phone charges correctly. To show the correct battery percentage I must reboot the phone.

I know this has already been reported by several users, just wanted to share my experience. ;)
