After two days of testing final v6 I can finally say, I have no problems, signal loss or anything else. Just great performance and amazing battery life!

Btw I am using smartass v2 / sio with power module.

It seems to me, that the only thing that seems to drain the battery a little, is wifi.

But I guess this is because of the old kernel source. When I switch off wifi, my battery lasts much longer than otherwise.

Never mind, Great work Deep and I hope you will not stop development for sxp! :)

Looking forward to test new stuff from you!

everything is ok :) i had a bug , atleast i think its a bug , it was time to charge the phone and so i did , i plugged in the charger and restarted the phone after a couple of minutes of charging and when the phone turned on it said that it had 77% battery , when it had like >10% when i plugged it .... is this a bug or is this some kind of unused battery not calculated by the phone ?
[Sony Xperia P, U, Sola, Go] casca:
how many "minutes" did it pass? don't forget the Xperia P has a boost charging mode until it reaches 80% and then it goes a bit slower
[Sony Xperia P, U, Sola, Go] Gaurav8180:
Hey everyone, look at this screenshot, this is very shocking :(

My Android os is eating my battery.

This has happened when I enabled the extended stand by mode.

Can anybody elaborate this???
[Sony Xperia P, U, Sola, Go] casca:
you have something draining it I think
[Sony Xperia P, U, Sola, Go] Gaurav8180:
Actually my bluetooth was connected to hands free for almost 4 hours, but this cannot be the reason as i used to use my bluetooth hand free very often or you can say daily and the battery drain was 3-4 % max and today it consumed almost 20-25 %. This is very strange. :(

Now I have disabled extended mode, lets see what's gonna happen now.
[Sony Xperia P, U, Sola, Go] casca:
if you don't have any app draining it, then it's a bit weird indeed. but i've seen some weird sh*t happening with this phone...
[Sony Xperia P, U, Sola, Go] BeDesireS:
I have the same issue most of the time! But I am not using extendend stand by mode.

Don`t know what it is that drains the battery in android os, but it happens quite often!
[Sony Xperia P, U, Sola, Go] Sephirothrx7:
Install better battery stats, you can find here on xda. It should be able to show what's draining the battery.

i cannot figure out why the XP isnt smooth in games as SGII , i have noticed playing with my friend next to each other , in temple run or subway surfers his gameplay is much smoother than mine , they have the same GPU , cpu doesnt really matter here , what could the problem be ?
[Sony Xperia P, U, Sola, Go] megablakbar:
Try a different governor (my xp is very fast it won the sgiii in opening nfsmw):D
[Sony Xperia P, U, Sola, Go] Eason85:
With the Brains rom do we still have to delete/rename the whole init.d/modules folder? Does that mean we can't use any of the non-standard governors?
[Sony Xperia P, U, Sola, Go] xRegrets:
If I'm not wrong, SGII Mali-400 has 4 cores while XP Mali-400 is dual-core. Which is why they're different.
[Sony Xperia P, U, Sola, Go] Gaurav8180:
I think SG III is powered by quad core. But SG II comes with a dual core processor, that is cortex A9.
[Sony Xperia P, U, Sola, Go] megablakbar:
Yea your right!
[Sony Xperia P, U, Sola, Go] OmarBizreh:
I remember I read somewhere on the internet that Xperia P has the Single Core version of Mali-400. not sure if that website have true info.
[Sony Xperia P, U, Sola, Go] OmarBizreh:
Use the version without governors, that version comes with default governors that you can find in Sony's stock kernel. those for sure have no issues if used with Xperia P :)

If you are going to use the one without governors then no you don't need to delete anything from the rom :)
[Sony Xperia P, U, Sola, Go] Gaurav8180:
Hi deep, i am using v6 w/o gov but i still have 6 governors. Power save, conservative, on demand, smartassv2, user space, performance????
[Sony Xperia P, U, Sola, Go] OmarBizreh:
I guess I have made a mistake by saying without governors. because by that I meant that hotplug and pegasusq are removed in that version.

and yet I expected users to know that by them selves :p

My mistake :angel:
[Sony Xperia P, U, Sola, Go] kudaj316:
Whoooow...deep is back, btw deep no issues anymore,using v6 final with gov. And power module. Im using stock rom,
[Sony Xperia P, U, Sola, Go] xRegrets:
Currently using Thebrainsrom with the final v6 kernel w/o extra governors, experiencing good battery life & smooth UI. Using smartassv2 as governor :) My reception seems to be fine too.
[Sony Xperia P, U, Sola, Go] Eason85:
Curious, what is "good" battery life on the P for you? I got 3 hours of screen time.
[Sony Xperia P, U, Sola, Go] megablakbar:
Guys I have flashed the 6.1.1.b.54 ftf but when I flashed the kernel I always get a notification telling me there is a software update here is a screenshot
[Sony Xperia P, U, Sola, Go] Irseq:
Delete UpdateCenter from system/app.
[Sony Xperia P, U, Sola, Go] Hefko:

[Sony Xperia P, U, Sola, Go] megablakbar:
Yup that's a good choice I don't even use it

Edit:after deleting it disappeared!
[Sony Xperia P, U, Sola, Go] Sephirothrx7:
If I remember well, sony doesnt recommend OTA update after unlocking bootloader, so it help to remove anyway.
[Sony Xperia P, U, Sola, Go] OmarBizreh:
I have detected why this issue is happening. in ramdisk I forgot to change version build to 6.1.1.B.1.54

The fix will be in next release (once the new source code is out, or once I am done with the stupid project of mine :( )
[Sony Xperia P, U, Sola, Go] megablakbar:
May god help you with your stupid project:D
[Sony Xperia P, U, Sola, Go] nicolassp:
very nice kernel deep :) when i enabled gpu 2d acceleration though the screen was getting pink when i was touching it..i restarted and it's ok but sometimes it lags..

Ps: i uninstalled weather widget with root uninstaller..Does anyone have it in cwm package to install it again please? I own xperia p with latest firmware..
[Sony Xperia P, U, Sola, Go] nicolassp:
Deep battery indicator i think is wrong..It says a percentage of power but when i restart it gets higher.Yesterday i plugged the phone to the wall charger..for 2 hours.It said 2% of battery left..I restarted and it was 100%.I also use the power module..(when i enable 2d gpu rendering i see lags..)
[Sony Xperia P, U, Sola, Go] Sephirothrx7:
I had similar problem even with stock kernel, dont know if it's related to kernel or rom.
[Sony Xperia P, U, Sola, Go] zaji06:
DEEP , Can you add LulzactiveQ governoor and I/O scheduler???

why? because with pegasusq i lost signal , other governors work fine

thank for answer
[Sony Xperia P, U, Sola, Go] chewdaniel:
go read the OP...
[Sony Xperia P, U, Sola, Go] sonnyxperia:

[Sony Xperia P, U, Sola, Go] megablakbar:
I think this is a rom related, sony plz fix it
[Sony Xperia P, U, Sola, Go] zaji06:
:( I have delete this fotlder , signal droping still with pesasusQ governor
[Sony Xperia P, U, Sola, Go] CaioA2:
Deep, i'm facing some problems with your v6test8... :(

Sometimes when I was watching some videos on youtube, my xperia p crashes without explanation ... Nothing works after that, nor touches the screen, or click the home button, or put / remove charger .. Only the combination Power + Vol worked up, probably because it is a Function "outside" the system (do not know, some instruction embedded in SoC / Kernel :confused:)

This happened about 4 times. In the first two used Power + Vol Up, in the third it rebooted to the boot screen, but crashed a few seconds later, and then he crashes again, but this time he restarted the kernel (I noticed this because the red light that appears when you connect the USB while the phone is off - the phone was in charger... ). The fourth time, he restarted the kernel directly ...

This did not happen in your other kernels, I'm trying to reproduce the problem again, this time running logcat ...

Thanks in advance (and sorry for bad english),

Caio Amaral

Edit:

I found a strange line on logcat, take a look:

"W/OSTTRACE( 1536): ? WARN :video/components/h264dec/arm_nmf/proxynmf/../../../h264dec/arm_nmf/decoder/src/host_decoder.cpp:1403:<TS> : ER455584"

Maybe this was making the problem?

SUGGESTION:

Deep, put an 600Mhz state in kernel, i think this will make better battery use..

Explanation:

I was using perfmon (found here at XDA), and it showed me (at least when playing video) the pegasusq is 400mhz to 800mhz changing incessantly .. an 600mhz probably will help to stop a litle this changes..
[Sony Xperia P, U, Sola, Go] huseinn:
I had very bad battery drain rate now, from full charge, my battery only last for abut 10 hours with sometimes checking twitter... :(:(
[Sony Xperia P, U, Sola, Go] OmarBizreh:
1. For those how are having issues with pegasusq governors PLEASE PLEASE PLEASE use the version without extra governors as I said many times before that's the only solution I could do. Please stop posting about it :)

2. For the battery statistics issue it is related to the kernel because the driver needs an update and I can't update it unless Sony releases the new source code. Sorry about that guys :(

3. As for the video issue from the log file I can conclude it's a driver issue, though it's strange why it happened now as I didn't edit anything that has to do with video performance (last edit was in version 5), have you attempted to clean caches? if yes, are you running any init.d script for better graphics performance? or have you added any build.prop value for better graphics performance? if yes then a conflict might be happening between the new values and the graphics driver.

4. For those who are experiencing lags when enabling Force 2D graphics GPU rendering, simply disable it, some other script / mod is causing conflicts. but when I enabled it I experienced nothing bad (and I didn't have init.d scripts nor build.prop values at that time).

5. Why the hell Sony isn't releasing that source code :( They have released many source codes but non for this device -_-

I know it's frustrating to have those issues, but honestly I can't do anything without the new drivers :-/

I keep on checking the developer website at Sony every day or two, so don't worry, once it's out I will work on it. updating kernel source wont take more than one hour, I will compile and release at the same day hopping those issues will go, unless Sony messed up something in their new software update :-/

Moreover here is the link of Sony's website: Sony Developer World

Once I see the new source code release I will be putting a comment here to let you guys know about it :)

If someone saw the new source code on that website and didn't see a comment from me on this thread it means that I haven't saw it yet, and notifying me would be great :D
[Sony Xperia P, U, Sola, Go] nwayen:
As always, thank you Deep for the information and the all effort you put into making the Xperia P a better phone!

Sometimes my battery starts to drain, and according to BBS this is because of a kernel wakelock named "sia". I'm having problems pinpointing what drives "sia" to spike, which applications / processes are related to it, etc. Does anyone here happens to know what is causing "sia" to spike, and perhaps how to prevent it from doing so?
[Sony Xperia P, U, Sola, Go] Xperia_Fans:
Hi Deep can I using v6 final kernel without power module???
[Sony Xperia P, U, Sola, Go] OmarBizreh:
Can you please share more info, showing running processes and amount of battery they use would bet great :)

Ya sure you can, it's not a must if it's not there the kernel will just ignore it's use and continue working like before :)
[Sony Xperia P, U, Sola, Go] Xperia_Fans:
Thanks Deep...the v6 final can install power module
[Sony Xperia P, U, Sola, Go] Xperia_Fans:
Do you have install power module???
[Sony Xperia P, U, Sola, Go] arnes_king:
hey all if any of you have the "Whats up" app installed then you need to know that it drains the battery mega fast, when i have it installed the battery drains on idle novernight 15-20% and when i deinstall it it is normail again with 1% battery drain over night
[Sony Xperia P, U, Sola, Go] neverhood11:
Yes, install power module..
[Sony Xperia P, U, Sola, Go] stole38:
the kernel officially rocks :D and i have proof

btw Deep , look at those red circles , those are Huge Awake periods for the phone in the middle of the night , the phone refuses to go to sleep or something wakes it up in the middle of the night , it might be Brains Rom but i dont know , it bothers me
[Sony Xperia P, U, Sola, Go] nwayen:
Will do when the drain pop ups again!

Do you mean WhatsApp? If so, I have it installed, get loads of messages, but it doesn't drain my battery at all. Usually I lose 2-3% every night.
[Sony Xperia P, U, Sola, Go] josie87:
Hi deep,

Using v6 final now with governors on stock. Awesome! Smooth! Good battery life!
[Sony Xperia P, U, Sola, Go] kudaj316:
How can i uninstall power module?
[Sony Xperia P, U, Sola, Go] chewdaniel:
if u used my method then it's very simple. just browse to the /system/lib/modules directory and delete m1.ko
[Sony Xperia P, U, Sola, Go] kudaj316:
thats what i have in mind, just want to be sure.....thanks chew;)
[Sony Xperia P, U, Sola, Go] Sephirothrx7:
Install better battery stats, it will show you what's keeping the lock. You can find here on xda, give a good read to learn how it works.

Yes same here I also have install it but. The battery just drain like normally...so strange
[Sony Xperia P, U, Sola, Go] OmarBizreh:
Hey guys sorry for my late reply :)

As for what @stole38 said about huge wakes ups during night, I recall i had the same thing but the thing is I started having those after I have changed the firmware I have installed on my device. I can only conclude it's because of the different versions between the source code of the kernel and the version of the update running on your devices.

If anyone could kindly test v2 or v3 (not version 6 test 2, I mean by v2, the real version 2 :) )

The problem stole38 is reporting if I'm not mistaken it wasn't present at version 2 or 3. so if anyone could please test it out for me. I don't want to keep on blaming the difference between Sony's latest update and kernel source code version.

So if the problem is still there on version 2 or 3 that means it's mostly because of the version differences between kernel and Sony's latest update.

Nevertheless I will keep on digging for a solution, maybe I can find a temp solution until the new source code is out.

Last question, does the wake ups happen even after the power module is installed?

For those who have installed power module, have you noticed any difference?!

To be honest I got kinda lost from comments after stole38. so if anyone having issues please post them back again with more details so I don't get lost again :p :cool:

it's now 2:30AM I will be back tomorrow at 12PM (i'm +2GMT) to check for comments :)
[Sony Xperia P, U, Sola, Go] kudaj316:
Honestly deep i find no difference on installing the power module, or maybe im jus to busy using my device everyday that everything feels normal for me,

edit: what does power module really do?
[Sony Xperia P, U, Sola, Go] chewdaniel:
it's supposed to manage power in diff ways, altho Deep already mentioned that he doesn't know if it will make any difference at all since the powermodule usually requires a bios to work... the target machine it's supposed to be running on are actually linux computers :D
[Sony Xperia P, U, Sola, Go] prithvi999:
Hi deep I 've installed v6 without governors but my. 3g s not working pls help :(
[Sony Xperia P, U, Sola, Go] OmarBizreh:
Just what chewdaniel said (quoted him below) it might make a difference and might not, at also might need a bios (according to the documentation) and might need few things from the bios that can be found on the phone. no one knows. that's why I'm asking for feedbacks about it since it's the only way I can determine if it's helping or not.

+1 :D

So far no one said it's not working. so I would recommend the following:

1. Clearing cache and dalvike cache

2. check if there are tweaks in build.prop for improving 3G connectivity (Try removing them)

3. check if there are init.d scripts for improving 3G (Try removing them)

4. check in settings what is the setting for network mode. maybe for some unknown reason it has been changed to GSM only. (you can check it at: Settings -> Wireless and Network (the group of settings where you turn on wifi, bluetooth...etc) -> More Settings -> Mobile Networks -> Network Mode.

If you still have issues tell me about it with some more details so I can come up with a solution :)
[Sony Xperia P, U, Sola, Go] CaioA2:
Well, try these tips from Deepunknow, and if it fails, connect to a wifi network and open the default browser, probably the network settings (mms/3g) are missing ...
[Sony Xperia P, U, Sola, Go] smoker46:
Hi!

i'm sorry for the stupid question but i'm new on this phone and i didn't find anything in the Q&A forum.

This kernel can be installed with a locked bootloader?

To install it i need flashboot, can someone link a guide?

Thanks and sorry for the noob question and for my bad english!
[Sony Xperia P, U, Sola, Go] Gaurav8180:
No dude, any custom kernel can only be flashed on unlocked bootloader.
[Sony Xperia P, U, Sola, Go] smoker46:
Thanks for the kind answer! to install the kernel (after the unlock of the bootloader) i need to simply ose flashtool and select the kernel img?
[Sony Xperia P, U, Sola, Go] OmarBizreh:
Nope, you will need fastboot and fastboot drivers installed on your pc.

then type this command:

fastboot flash boot boot.img

Look at this youtube video: Flash Custom Kernel

It's for the Xperia Ray, but both have the same way of flashing.

and just ignore the way the person in the video talk, it may sound like he is sleep talking :p

Edit:

Fastboot Drivers

Be sure to check your device from the list + the last two options as they are drivers for using Adb and Fastboot.

if you don't know how to flash, download Droid Manager (link in my signature)

make sure you have USB Debugging turned on (under Settings -> Developer Options)

connect your device to your pc, run Droid manager.

Go to Fastboot Tab, Click Browse button and point it to the kernel you want to flash.

BE SURE TO CHECK THE BOOT PARTITION AND NOT ANYTHING ELSE OR YOU WILL BRICK YOUR DEVICE.
[Sony Xperia P, U, Sola, Go] Hefko:
After week of testing I can say, that my phone is a way faster without power module. With power module my phone became laggy after few days and needed restart. Anyway, your kernel boost my phone a lot and I looking forward to update. Thank you :)

[Sony Xperia P, U, Sola, Go] stole38:
after reading your post i quickly ran a Quadrant bench , it showed me a score of 2000 , while the GPU performance was cut in half ... and i was like let my try GTA Vice City it ran flawlessly (because on stock kernel which had 2700 on quad sometimes it studdered)
[Sony Xperia P, U, Sola, Go] Gaurav8180:
Hi deep! I have problem here, sometimes my bluetooth doesn't work, only reboot brings it back to work. This has happened to me twice in past 2-3 days. Can you do something for this??? Or this issue could be of outdated drivers???

Using stock rom . 54, v6 w/o governors.
[Sony Xperia P, U, Sola, Go] gvijayaratnam:
Hi,

Can someone help me by providing the steps to flash this kernel to my SXP. I have rooted and installed CWM. I tried with flash tool, but failed.

thanks in advamnce

GK
[Sony Xperia P, U, Sola, Go] sonnyxperia:
flashtools is for flashing firmware, for flashing kernel use fastboot

did you unlock your bootloader?
[Sony Xperia P, U, Sola, Go] neverhood11:
Failed? What did u do? What was wrong?
[Sony Xperia P, U, Sola, Go] kudaj316:
Deep can u make your kernel compatible with cm9?coz cm is almost at the final stage, and if im gonna use that rom i want the kernel to be yours....
[Sony Xperia P, U, Sola, Go] neverhood11:
Yes please :) Love your kernel and I wish I could use it with CM ;) I`m not going back to stock, because CM is almost perfect :)
[Sony Xperia P, U, Sola, Go] arnes_king:
The battery life is really perfect after uninstalling apps which i thought that are draining it too much like (whats up), after almost 9 hours of usage i still have 84% left :D Battery drain overnight is about 1%
[Sony Xperia P, U, Sola, Go] OmarBizreh:
I remember I had it once, but I tried turning bluetooth on three or four times then it worked without rebooting. I don't know if it's driver related. if it fails again please execute this: dmesg > /sdcard/dmesg.txt (via Android Terminal)

and send me dmesg.txt so I can take a look at the reason :)

Consider it done. I will be working on it tonight, I'm sick of the stupid graduation project, leaving it for today only wont mess up anything :p

Will do so my friend :D

Though I want someone to test the kernel for me if possible :)
[Sony Xperia P, U, Sola, Go] megablakbar:
Sure:D
[Sony Xperia P, U, Sola, Go] OmarBizreh:
source code downloaded :D

gonna have dinner and work on this thing. Expect a test release for CM roms within an hour :)

as for this one (for stock) I will update it to version 6.1 to include the missing schedulers :)
[Sony Xperia P, U, Sola, Go] neverhood11:
You`re the best and I`m ready to test :good:
[Sony Xperia P, U, Sola, Go] huseinn:
cant wait for the newest version :D , BTW deep, My capacitive button lights not as bright as it should, I mean, the BACK button is the brightest and

Menu button has the lowest brightness... :confused: maybe related to ur kernel.? just curios what cause it and how to bring it back..anyone got

this.?

Thanks :highfive:
[Sony Xperia P, U, Sola, Go] megablakbar:
Yes I am facing this I thought it is related to stock rom (a bug by sony):p
[Sony Xperia P, U, Sola, Go] OmarBizreh:
By the way if I'm not mistaken on user reported it was working on CM roms.

I was going through source code from Sony and CM Team. both are the same !!

So can someone please recheck if it is working :)
[Sony Xperia P, U, Sola, Go] neverhood11:
I tried, but ended up with bootloop..
[Sony Xperia P, U, Sola, Go] megablakbar:
Deep what about the brightness of the buttons of the transparent bar:confused:
[Sony Xperia P, U, Sola, Go] OmarBizreh:
then I guess I have a ramdisk issue that's why it's not booting on CM Roms.

I suppose they are not kernel related as I'm using Sony's source code.

Did you have the same issue when using stock kernel?! or any other custom kernel?
[Sony Xperia P, U, Sola, Go] megablakbar:
I'll flash stock kernel and report back

---------- Post added at 08:43 PM ---------- Previous post was at 08:33 PM ----------
