I flashed the version compiled with Linaro 4.8 (beta 2(2)) last night and I must say everything works fine, no issues so far. UI is as smooth as in the previous test version and I didn't experience a single lag when gaming (Temple Run II) or watching 1080p hd movies from my NAS over wifi. Antutu benchmark yields scores between 6800 and 6950. For me, the Linaro 4.8 version is good to go :good:
[Sony Xperia P, U, Sola, Go] Creqaw:
Uhm, kernel_Beta2(2).elf and kernel_Beta2.elf are the same file. I did a hash check and they are the same.

//edit I'm referring to these files: http://www.mediafire.com/?55a9mq0xg6bi2#myfiles maybe you have different ones?
[Sony Xperia P, U, Sola, Go] OmarBizreh:
Yes beta2(2) and beta2 are the same, whenever a file found ends with (2) this means I had a network issue which made the file be uploaded twice :-/ I'm now releasing the final version of 8.2 which is compile with linaro 4.8 and updated to 3.0.77 (check log post in the coming post to see what's new ;) )

Edit:

Sorry about yesterday I had power cut off for like 30 minutes but when it was back I was already in bed, so was kinda lazy to go up again and turn on my laptop to upload the kernel :p )
[Sony Xperia P, U, Sola, Go] OmarBizreh:
Version 8.2 Change Log

Updated linux kernel source code to 3.0.77

Compiled using Linaro 4.8.1

Added Google Snappy Drivers

Enabled zCache and zRam

Added missing flags for a complete -O2 optimization.

------------------------------------------------------------------------------------------------------

Download

Link removed, Linaro 4.8.1 is known to cause sudden reboots (according to feedbacks) while 4.7 doesn't will update the kernel tonight so I removed current download link :)

Sliding_XP v8.2 (Wipe cache and dalvike cache, or kernel will reboot once android finishes booting up.)

------------------------------------------------------------------------------------------------------

Side Note

You may have heard of XDA - DevCon, well I got an invitation to that event but my only issue is I'm financially tied. This kernel got 760+ downloads for v8.1.1 (and 10$ donations which I'm really grateful for :) donations are calculated for each version.), I really appreciate it if at least each one of you guys donate a 1$ so I can afford paying for the plane ticket :).

Thanks for all who tested v8.2 or offered testing the kernel before it's release :)

[Sony Xperia P, U, Sola, Go] Canalope86:
Awesome! Thanks for developing the best kernel ever made!
[Sony Xperia P, U, Sola, Go] azeez77:
Got boot loop even after wipe cache and dalvike cache it boots the says android updating optimising apps 1 of 24 does all 24 then reboots
[Sony Xperia P, U, Sola, Go] Canalope86:
Got random reboot when phone started up, will try to flash again and see if the problem persists. (Lionheart/row)

Edit1:

Kernel seems to work fine after reflashing it. No reboot for 20 minutes yet...

I think reflashing solved my issue.

Edit2:

Phone rebooted again when I was playing Temple Run II. Didn't have those issues with the 8.2 test version.
[Sony Xperia P, U, Sola, Go] Jamal_RS:
Till now I had 1 time random reboot,

But performance is awesome

The new record(hotplogx/row):

Thanks Deep

Edit:add hanging and tapatalk fc too

[Sony Xperia P, U, Sola, Go] OmarBizreh:
Random reboots :(

Please for those who are not having them post your governors, and IO schedulers.

v8.2 is the first version I compile with Linaro, I'm having a feeling it's caused because of toolchain and governors are not meant to be together :p

But yesterday those who tested it said no reboots after wiping cache and dalvik cache. so I'm gonna need more details to be able to determine the issue. :)
[Sony Xperia P, U, Sola, Go] Canalope86:
Sometimes, my phone hangs at startup...Will try different governors and IO schedulers and see if the problems persist.

Edit:

Phone hanging when optimizing apps during first boot and rebooting after starting up. Tested on lionheart/row and pegasusq/sio.

Didn't have these issues with the 8.2 test version compiled with Linaro 4.7.
[Sony Xperia P, U, Sola, Go] androizers:
I'm Using The kernel_beta2(2).elf and finally happy to c a flawless effects n lagg free....

No Random Reboot, No Bugs Till Now!!

[MENTION=4313825]DeepUnknown[/MENTION], Is Final 8.2 same as kernel_beta2(2).elf or some addition tweaks or drivers have been added to that??
[Sony Xperia P, U, Sola, Go] OmarBizreh:
The one you are using is compiled using Linaro 4.7, the final release is compiled using linaro 4.8.1 :)
[Sony Xperia P, U, Sola, Go] androizers:
But Somebody was sayin that Beta2 was compiled with linaro 4.8 if em not wrong...

Nevermind, I'm going to give it a try by flashing it with cwm, then c if I got random reboots or not!!

Will Edit my post in just 2-3 mins!! :rolleyes:
[Sony Xperia P, U, Sola, Go] OmarBizreh:
Ya things got a bit confused for users, and no Beta2 & beta2(2) are the same files which where uploaded twice because of network issue, and they are both compiled with linaro 4.7 :-/
[Sony Xperia P, U, Sola, Go] xgunax:
i tryed version 8.2, flashed with flastool, then turn on , wipe cache and dalvik, turn it on and freeze as soon as it enter in lockscreen, then also randon reboot, back to test kernel :)
[Sony Xperia P, U, Sola, Go] OmarBizreh:
By test kernel you mean the one called: Beta2

or the the first 8.2 test I released?!

I want to know so I can make a decision on keeping linaro or switch back to old toolchain.
[Sony Xperia P, U, Sola, Go] Canalope86:
I didn't have the hanging and reboot issues with the beta2 test version, using lionheart/row.
[Sony Xperia P, U, Sola, Go] OmarBizreh:
Then linaro 4.7 here I come :)

No worries it wont have a major performance decrease. Because the first 8.2 beta release was compiled using GCC 4.4.3 and yet users where extremely happy with the result. in worst cases if Linaro still gives issues I will switch back to GCC 4.4.3 to ensure stability :D
[Sony Xperia P, U, Sola, Go] Canalope86:
Seems like an excellent plan :good:. Just flashed back the 8.2 beta2 version and all issues are gone :D. So it seems that Linaro 4.8 was causing the issues and 4.7 is fine.
[Sony Xperia P, U, Sola, Go] OmarBizreh:
Will update it tonight and see if any other improvements can be brought to the kernel ;)
[Sony Xperia P, U, Sola, Go] whalesplaho:
hope everything goes fine... currently using Kernel Beta 2 & no issues!!!

any news about touch recovery & vibrate when to enter recovery?
[Sony Xperia P, U, Sola, Go] Gaurav8180:
Bro this kernel.is based on sony's source code .so i think you should try it with the sony stock rom.

Hope it helps you.:D
[Sony Xperia P, U, Sola, Go] mrbrunor:
i'm currently using Brains ROM with this Kernel. It is working perfectly.

But i flashed SlideV4 Kernel before the ROM xD
[Sony Xperia P, U, Sola, Go] OmarBizreh:
version 5 is near complete. If you could please remind me with your requests (by "you" I mean all users)

I'm having a feeling I forgot something :(

As for adding 100MHz I think it's better to ditch it for now, device acting crazy when attempting to wake it up :(

Anything else you want to see in the next version?!
[Sony Xperia P, U, Sola, Go] rpiniones:
I have a quick question.. I backed up using DUP option.. The backup size is small 16.5 mb overall.. Is it a valid backup? Or should I use tar???
[Sony Xperia P, U, Sola, Go] kudaj316:
i guess this kernel is near perfect already, recovery fixed, overclocked, governors, what more can we ask for,:laugh: good decision you ditched 100mhz, it drains battery faster...higher watts than 200mhz.
[Sony Xperia P, U, Sola, Go] Gaurav8180:
it is a valid backup but according to me, .dup cannot be flashed via cwm its better you use .tar . tar would take almost 500mb - 1GB. So be prepared with memory size:laugh:

hope it helps you:D
[Sony Xperia P, U, Sola, Go] reiteravi:
dup relies on blobs so there is the rest of the backup

use tar if u want to copy it complete elsewhere
[Sony Xperia P, U, Sola, Go] nicolassp:
Hello, i want to ask something.. The settings button next to home button is not sensitive enough as home and return button.. Can it be fixed setting higher sensitivity maybe? I have seen that all users have reported the less sensitive settings button
[Sony Xperia P, U, Sola, Go] rpiniones:
I checked the blobs folder its full of files. Its kinda messy, I use tar option now.. More organized becoz the files are packed inside the tar files.. Thanks a lot
[Sony Xperia P, U, Sola, Go] prom85:
I just can mount my sd in mass storage mode or if I enable automatic installing PC Companion and always clicking "install"...

But no matter what I do, I can't get usb debugging to work... My phone always shows usb debugging enabled, but I can't connect to it...

Does anyone have a solution for that?
[Sony Xperia P, U, Sola, Go] OmarBizreh:
Everything is fine over here, did you try removing cache and dalvik cache?

if that didn't help, remove the phone driver from device manager on your computer then try again it should work :)
[Sony Xperia P, U, Sola, Go] Narag:
Flashed test version of V5 from 18:40, everything's working well so far on TheBrain's V03 ROM ...

Thanks !

Edit: After some reboots I had to go back to V4 if it's caused by new version :(

pegasusq/sio
[Sony Xperia P, U, Sola, Go] prom85:
ok, installing adb driver manually did solve the adb problem... the other problem still remains, no matter what I do... But at least now I have a solution for everything... so thx
[Sony Xperia P, U, Sola, Go] OmarBizreh:
try removing all drivers related to your device (except for adb drivers since you said they are working now) and install these drivers they come with flashtool and they solve all issues related to your issue (at least 90% of the time they do)

just a reminder when you run the installer just check the drivers of your device because it includes drivers for other xperia phones.

Hope this will help solving your issue :)
[Sony Xperia P, U, Sola, Go] prom85:
I will try again... But actually I've installed the drivers from latest flashtool for my device...
[Sony Xperia P, U, Sola, Go] OmarBizreh:
Usually the procedures taken in such cases are:

1. Trying a different USB port.

2. Removing all drivers related to the device effected and reinstalling them.

3. If still fails to be recognized, try a different PC.

4. Try a different cable sometimes if the cable is damaged even though PC can see there is a device connected but a damaged cable will effect the device (but I doubt this is your case because things were normal with you)

5. Remove PC Companion, clean registry (using software such as CCleaner) and re-install PC Companion, some forums suggest doing that.
[Sony Xperia P, U, Sola, Go] prom85:
thanks for your help... actually it's not related to your kernel I can say now... although some time back I figured out that flashing another kernel solved the usb problem, flashing back and the problem reappeared... But at the moment I just have another problem, because even with stock kernel it does not work... and I'm missing the mount message in the top bar when usb is connected... :-/

But thanks for your help so far

PS: clean reinstall solved all problems...
[Sony Xperia P, U, Sola, Go] neverhood11:
I just tried to flash no-overclocking version, because of some reboots that appeared and now I have higher score in Quadrant then before with OC...how come? :P

With OC - 2700, without OC - almost 3000...
[Sony Xperia P, U, Sola, Go] Gaurav8180:
Try other governors like ondemand with sio. I am using the v5 from the last 28 hours, and have no reboots till now. Working awesome with me. V5 with sony stock rom(.54)

Hope it helps you:D
[Sony Xperia P, U, Sola, Go] OmarBizreh:
I'm thinking of ditching overclocking, It caused my device to get really hot, and made few issues while on high work load :-/
[Sony Xperia P, U, Sola, Go] Creqaw:
Also going back to 8.2 beta, 8.2 final worked for a few hours but then started to randomly reboot, also wiped dalvik en cache.

//edit I used PegasusQ and SIO.

[Sony Xperia P, U, Sola, Go] alee1730:
Were here Deep!! U disappeared, so I thought maybe you had already uploaded the 8.2 compiled by 4.8 cause I refreshed browser and found a second kernel uploaded! :D I apologise for misleading guys! :)

[Sony Xperia P, U, Sola, Go] stothegee:
Hi Deep!

great kernel, thanks for supporting our device! I got 2 questions if you dont mind: :angel:

1. Will you continue to update your cm9.1 kernel until cm10 is stable?

I am asking this because i am a huge miui fan and real miui is cyanogen mod based.

So i will not switch to jellybean until a cm10 based miui rom will appear. This will take a while i guess...

2. Is it possible to implement voltage control?

I know you dont like overclocking, me neither :)

I am more interested in in undervolting, to get better battery life...

Are the missing sources from st ericsson a problem for fine-tweaking low level stuff on our device?

I am kinda confused when looking at advanced kernels from other devices and compare their feature set with kernels for our xperia p...

Maybe you can explain a bit? :fingers-crossed:
[Sony Xperia P, U, Sola, Go] androizers:
+1 for the Voltage Control..... :D
[Sony Xperia P, U, Sola, Go] gvijayaratnam:
Hi Deep,

Is the random reboot bug is fixed?
[Sony Xperia P, U, Sola, Go] SKA67:
Download link is faulty
[Sony Xperia P, U, Sola, Go] OmarBizreh:
Download link was faulty because I was working on this :D

Let's hope Linaro 4.7 is truly error free :)

Download Link: Sliding_XP

I did some other changes, test this one to it's limits, I want to know if those changes bring any change ;)

Edit:

Please for the future don't quote long comments, it took me ages to be able to read all comments on this page :p

Edit 2:

And no I can't include voltage control because they are not known for XP chip. other kernel implement it (for other devices) because each freq has min and max value that are known, in our case it's not known :-/
[Sony Xperia P, U, Sola, Go] xgunax:
flashed via fastboot, no boot, stuck in Sony Logo, cant even go into recovery
[Sony Xperia P, U, Sola, Go] OmarBizreh:
Uploading another one, should be ready in 5 minutes (check Here for download :) )

Edit:

Upload finished :)

Edit 2:

So did it boot?!
[Sony Xperia P, U, Sola, Go] stothegee:
Thanks for the fast answer deep!

What about the cyanogenmod kernel? I guess no more updates then :crying:

Just keep in mind that there is no working cm10 yet, so peeps who want cm need to flash cm9.1 for now...

voltage control: No way to get that information about the chip? Could you please briefly describe what other tweaks/mods cant be implemented because of the missing source?

Would be much appreciated, cause i have no clue at all and im curious :angel:
[Sony Xperia P, U, Sola, Go] OmarBizreh:
There will be updates but I need to get this kernel done, I want someone to test it and make sure everything is going as planned then I will be moving on to the CM kernel :)

As for the list of things that can be done usually all that we care about is undervolting + overvolting + underclocking + overclocking, and we don't have all the info to do any of these :)
[Sony Xperia P, U, Sola, Go] xgunax:
flashed new one and booting

booted ;)

testing normal use.. calls etc

until now everything good! talked about 5 min, wifi connect, camera, sms,, normal use not affected.. perfomance smooth as im used with your kernel :)
[Sony Xperia P, U, Sola, Go] OmarBizreh:
booting as in booted into the system or booting as in you just booted up your phone and waiting for it to finish?! :confused:

Edit:

Thank you I just saw your edit.

I guess it's time to make official :)

I will give you like 15 minutes can you please test it with various apps and see it's performance & if there are any sudden reboots :)
[Sony Xperia P, U, Sola, Go] stothegee:
thanks so much deep! will be looking forward to the cm kernel!

:eek: Warning noob questions ahead :eek:

1. I was reading about governors (cause there are so many of them in this kernel :laugh:) and was wondering about the freq steps in your kernel.

From the things i was reading, the up/down scaling would profit from having more steps to go through? Thats good if the scaling function in a governor needs it, others can just skip them, right? like performance/powersave/minmax do.

2. Other devices have weird mhz steps like 387mhz, we have 200,400,800,1000. This is because of the missing informations about our chip, i suppose. The chip does in fact scale up and down, right? Its not all placebo i hope...

3. The governors with -q at the end (like pegasusq) have dual-core support, right?

The governors with -x at the end (ondemandx) include a deep-sleep profile, right? (so no need to set a screen-off profile?)

sry for the questions :confused:

Sorry for disappearing, I was putting final touches for Droid Manager v6, I thought I would release it tonight with this kernel, and hope for the best :)

As for this kernel no more tests, so if anyone would like to get the latest version simply download the latest link, I might need sometime to update the thread.

And to save you time and effort, here is the download link: Sliding_XP v8.2

Will upload the CWM flashable version once I update this thread :)

Thank you for your help. and I hope the 8.2 gives you what you need :)

not surprising, considering stock is interactive/cfq :)
[Sony Xperia P, U, Sola, Go] Minami I:
but ICS was ondemand.

i tried all governor in this kernel

and experienced that scaling gorvernor (like ondemand, wheatley...) shows little buggy.

timer gorvernor ( like smartass, interactive...) was faster than that.

pegasusQ has signal drop problem on my XP

when it comes to say about i/o scheduler,

noop not wake up phone from deep sleep sometime.

sio is good but has signal drop problem with some governor.

row is fastest but shows laggy scrolling sometime.
