Hi Deep! How are you doing? Any new test release that you would like us to try on our devices? Pls. let us know! Thanks a million for your incredible and hard work! :good:

EDIT: Do not hesitate to ask! We are here to help! ;)
[Sony Xperia P, U, Sola, Go] OmarBizreh:
Things got a bit messed up :(

After some modifications to improve kernel (which did accroding to [MENTION=4324242]vr2008[/MENTION]) recovery got broken.

BUT when I fixed recovery, kernel stopped booting to system >_>

when I fix kernel, recovery stops working T_T

I've just sent a test to vr2008 let's hope everything goes well now :)
[Sony Xperia P, U, Sola, Go] OmarBizreh:
Version 8.0 Change Log

Based on Sony's source code for Jelly Bean kernel.

Same old features of the ICS kernel.

Now using a different CWM recovery since it has some more useful stuff.

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

Download

Sliding_XP v8.0

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

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 1200+ downloads for v7.4.4, I really appreciate it if at least each one of you guys donate a 1$ so I can afford paying for the plane ticket :).

Special thanks to [MENTION=4324242]vr2008[/MENTION] who spent with me 5 hours testing and providing feedback according to my request :)

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

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

Coming Next

Patch update kernel to latest Linux Kernel source code

(I already patched it but something went wrong along the way which caused the kernel to bootloop when showing boot animation, so I had to start fresh from Sony's unmodified source)

Try to implement touch recovery.

Find a proper tool for making bootlogo because I didn't get lucky with Android Kernel Kitchen, bootlogo was pretty messed up :-/
[Sony Xperia P, U, Sola, Go] jioleight:
What kind of recovery did you included?
[Sony Xperia P, U, Sola, Go] hlcxcx:
Great news bro
[Sony Xperia P, U, Sola, Go] ItalDiamond2008:
Thanks a million for your hard work! Downloading and flashing it immediately! :good:

PS: I've just sent you a small donation mate.
[Sony Xperia P, U, Sola, Go] hlcxcx:
I just flash v8.0 and missing hotplug/hotplugx governor

Is there any chance to add this features soon?

BTW this version is fast and smooth with very good performance. Thanks in advance.
[Sony Xperia P, U, Sola, Go] Jaycel0820:
wow i like the recovery!
[Sony Xperia P, U, Sola, Go] jleonnn:
Hi first I'd like to thank you for the kernel pretty smooth :D

But I can't seem to boot into recovery; I'm using fidelity JB rom now and when I press the volume down button during boot I can't enter recovery :( Is there like a special way to boot int recovery for this kernel? Thanks
[Sony Xperia P, U, Sola, Go] Jaycel0820:
volume up mate not volume down:)

no such problem with me
[Sony Xperia P, U, Sola, Go] Xperia_Fans:
Thank brother finally saw your new kernel ;)

Flashed The Kernel Today,

Nd The Battery Was Super Awesome... :D

Was Using My fone For Bout 20 Mins Consistently, Only 3% Drop!!!

Really Love it, Even More Than ICS Versions...

So [MENTION=4313825]DeepUnknown[/MENTION], What bout adding Undervolting this time to this kernel, I wish if v cud c that, as it really helps in gaining more battery, nd what bout that #FastCharge Patch, that I PM uh!!!:confused:

Have u think of that...

Edit: No CWM this Time...

No Blink of Light n Illumination When at Sony Boot Logo... Directly Fone Switch on accompanying with Boot Animation!
[Sony Xperia P, U, Sola, Go] chewdaniel:
CWM is working for me... and it looks pretty :D
[Sony Xperia P, U, Sola, Go] androizers:
But How :confused:, R u using a power menu or just manually pressing Volume+....

Btw, do u see led n illumination blinking when booting....

Edit: Which one u have flashed, Stock_CWM.zip or Kernel_1.elf??
[Sony Xperia P, U, Sola, Go] Jaycel0820:
is this your first time using a kernel with recovery?

if you press volume up only once then it will not work

you have to press it many times

im using this kernel and CWM works and by the way im using kernel.elf and flash it via flashtool
[Sony Xperia P, U, Sola, Go] bflmpsvz:
How many times exactly and how long should I press the volume button?

Can someone post screens of the new recovery please?

[Sony Xperia P, U, Sola, Go] entrysky:
Thanks. It not work for me
[Sony Xperia P, U, Sola, Go] ItalDiamond2008:
I've also tried entering CWM many times by pressing VOL+UP key several times with no success! There's no way for me to enter CWM. Any suggestion? I do not have such problems with other kernels. I've flashed and re-flashed kernels with recoveries so many times without any problem whatsoever. Am I missing something this time? Thank you.;)
[Sony Xperia P, U, Sola, Go] nwayen:
You can, for instance, use ROM manager to boot into recovery from inside the app.
[Sony Xperia P, U, Sola, Go] Jaycel0820:
i press volume up many times until cwm comes i dont know why cwm is not working for you all but its working for me

what kernel did you use? the cwm kernel or the kernel.elf?

i use kernel.elf and i flash it tru flashtool
[Sony Xperia P, U, Sola, Go] hlcxcx:

[Sony Xperia P, U, Sola, Go] kudaj316:
The cwm zip version has no recovery...
[Sony Xperia P, U, Sola, Go] chewdaniel:
i'm using fastboot version too... i can never understand why ppl would want to use recovery to flash a kernel...

u HAD to use fastboot to unlock BL and to flash the initial kernel with recovery right?

so what's the logic of using recovery to flash a kernel? guess i'll never know :/
[Sony Xperia P, U, Sola, Go] entrysky:
Stock-CWM.zip no CWM Recovery.

Flash kernel-1.elf anythings work. Thanks.
[Sony Xperia P, U, Sola, Go] OmarBizreh:
I don't get it, why recovery is not working when flashing the zip file !! The elf file in the CWM version is the same one that is included in the download folder except it's in a zip file and not a stand alone file.

Please provide me with the recovery log file, it can be found at: Cache -> Recovery -> Last_Log

Thanks a lot my friend I really appreciate it :)
[Sony Xperia P, U, Sola, Go] Waledac:
The recovery is the same as it was in the previous Kernels for me but in the change log u said u are using different recovery o.O
[Sony Xperia P, U, Sola, Go] Jaycel0820:
no its true that the recovery is different like color also added some option but don't know how to use it hehe hope deep expain to us , but never mind as long as it has good performance and battery friendly its fine for me

thanks deep!
[Sony Xperia P, U, Sola, Go] Waledac:
Oops i flashed stock then again Deep's kernel now the I have the new Recovery ... :D Thank u Deep for your hardwork :)

and i did not get the location of the log file :(
[Sony Xperia P, U, Sola, Go] atarum0r0:
Great work, kernel is very fine. :good:

which are the best Governor/Schduler?
[Sony Xperia P, U, Sola, Go] Waledac:

Is there any chance to add hotplugx and lazy governor?
[Sony Xperia P, U, Sola, Go] krasus1111:
hmmm WiFi is cont connect to any network witchout any secutity and filter. Anbyody haw any idea? In 7.4.4 version and ICS rom, STOCK JB on stock kernel is OK
[Sony Xperia P, U, Sola, Go] OmarBizreh:
Hey guys I barely have time today I have a homework due tomorrow (7 problems to solve :@ )

For now I need one thing from you guys: Confirm if wifi issue exists because [MENTION=3320285]krasus1111[/MENTION] reported an issue about wifi

AS for me, To do tomorrow:

Will reply to all pm's

Add hotplugx governor (though I recall it was reported to cause sudden reboots to the phone, can any one confirm that)

Start patch updating Linux kernel since it has many bug fixes which will also improve kernel performance

Mali drivers are up to date out of the box. Sony updated them for JellyBean I checked the source code :)

Keep those donations coming please, I really need to go to DevCon :( or else I wouldn't be asking for a donation, I enjoy what I do and I don't do it for money :) (Special thanks to those who already donated total of 6$ :D)

Add Fast AC charging (this will take some time, available patches are for other devices and using them without modification is useless since

they patch the wrong files for Xperia P and since it's power related I need to make sure I do it right or else it might brick the device once and for all and a motherboard replacement will be a MUST)

Add a tutorial for those who want to remove auto root from the kernel (I'm getting requests about it)
[Sony Xperia P, U, Sola, Go] chewdaniel:
wifi works without any prob here... don't know about unsecured network tho...
[Sony Xperia P, U, Sola, Go] atarum0r0:
Hi deep Thanks to your work. I m using enigma rom 4.0 and your kernel and i have not problems to now. Wifi work fine, the phone is fast, stable and battery life is good ;)
[Sony Xperia P, U, Sola, Go] vr2008:
same for me :( but kernel itself is really really fast and all my lags are gone.I can live without backup :D
[Sony Xperia P, U, Sola, Go] OmarBizreh:
Does it happen on a different kernel with a different recovery?!
[Sony Xperia P, U, Sola, Go] whalesplaho:
Woah... really missed out but no worries!!!

i guess tha autoroot is great!!! :) Superb work brov, flashing & downloading right away
[Sony Xperia P, U, Sola, Go] vr2008:
in ICS version (7.4.4) it was working ;)
[Sony Xperia P, U, Sola, Go] _nafets_:
Hey Deep,

i also have problems connecting to wlan.

No auto or manual connect.

[Sony Xperia P, U, Sola, Go] Hefko:
I do not see any bug. Everything works fine for me :)
[Sony Xperia P, U, Sola, Go] OmarBizreh:
I want to know if in another jellybean it is working, because recovery is compiled with device configuration and the ones I used where for ICS, so I want to know if it's because of device configuration or because there is some code I need to change :)
[Sony Xperia P, U, Sola, Go] HarryCustom:
Hi, I am sorry I've checked for a long time but I can't find this information: I have a rooted JB Xperia P, but it is still locked, can I use this kernel?

Hi Deep,

The Wi-Fi issue still exists :( I'm unable to connect at all to the wi-fi... The kernel works perfectly otherwise... as usual :)
[Sony Xperia P, U, Sola, Go] hlaraujo:
Flashed your kernel yesterday and everything works fine, no wifi issues here... CWM flash version does not have recovery though
[Sony Xperia P, U, Sola, Go] sau94:
Great work!

Hey Deep just flashed the jb kernel. Have to say it is the best and the fastest with low battery drain :D :good: :good:

Oh and the recovery looks great too :D

Btw dint encounter any errors with wlan :fingers-crossed:

Beer on the way! :highfive:
[Sony Xperia P, U, Sola, Go] krasus1111:
I did full wipe and WiFi is connected.

when i flash sliding_XP v.8 MAC address is chenged
[Sony Xperia P, U, Sola, Go] Alroid:
Rooting is one thing and unlocking bootloader is another.

Never flash a custom kernel on a device with locked bootloader because it can hard brick you device.

read this if you want more detail about unlocking BL. and remember that your guaranty and DRM will be lost after unlocking BL.

[Sony Xperia P, U, Sola, Go] CosmicDance:
Very weird, I flashed stock kernel, it has wifi, then i flashed slider, it's gone...reflashed stock, it's back again. So i'm sure it's the kernel... I flashed the .elf file. And yes, the CWM version doesn't have recovery....
[Sony Xperia P, U, Sola, Go] androizers:

If the MAC address changed then that could be the reason why my wifi isn't working as I've allowed only a set of MAC address to access my WiFi.

AFAIK, MAC address is part of the hardware and it cannot/shoudn't be changed...
[Sony Xperia P, U, Sola, Go] whalesplaho:
Edit: Sorry for posting off topic!

just wanna know again; did anyone experience led bar light on when operating tha mobile or charging but light off when screen off???

i just wanna again cos some says it normal & another person is telling me dat its not normal!

---------- Post added at 06:41 PM ---------- Previous post was at 06:38 PM ----------

doesnt work on Xperia 2012 i guess.... not working if battery cant be removed!:silly::p
[Sony Xperia P, U, Sola, Go] androizers:
There must b a system scripting conflict...

That can happen, not fully sure if its normal or not!!!

I guess it can work, n it doesn't have to do anything with the battery....

Just v have to securely backup our TA Partition and do Unlocking....

After trying some other custom rom n playing with that, just if v r curious to Relock Bootloader, Flash The Backup TA Partition and thats all!!! BOOM!! :eek::D

Bootloader Relocked like if v have Never UNLOCKED it EVER...

DRM keys r back with working Gracenote Download Info.. :cool:

different kernel, no problem making backup.

also, i cant go into recovery with V8 kernel with JB rom, tryied vol- vol+,
[Sony Xperia P, U, Sola, Go] _nafets_:
That is the problem, why wifi is not working!

The mac address is changed!

Now its the vendor MAC of the STMicroelectronics Chip is used, not the Sony MAC.
[Sony Xperia P, U, Sola, Go] krasus1111:
i'm know what is MAC Addres and maybe is software change?

why before flash kernel MAC is: D0:51:62:39:xx:xx and after MAC is: 00:80:E1:18:xx:xx :confused:
[Sony Xperia P, U, Sola, Go] androizers:
U r not getting my point....

Once the Bootloader is Unlocked, the DRM keys r deleted by default n v r left with none...

So y not v do simple process, simple backup the whole TA partition which all the info bout our fone like EMEI, Serial Number, DRM Keys n Other Private info of every individual fone!!!

Once They r backuped, v do official unlocking and when v here to bout Relock, simply Restore the backupes TA Partion n get DRM keys like v Never Unlocked The Bootloader Ever'!!!! :what::D

Mine seems to working fine....

Only a ignorable bugg...

When I connect the usb jig to fone and usb port to charger and switch on, the led shows the charging signal light n when screen off its shows normal....

Bt when I switch off the socket plug bt kept the usb jig connected to my fone and the screen off, the led indication still showing the light like the charger connected and its charging the fone...

So to get that back to normal, I have to switch on the screen and then the led goes off and show me the notification msg of Unplug the socket...

Bt I previously said, Its Ignorable,.,,

Nice idea brov.... didnt do dis before unlocking BL!!!

how can one backup TA?
[Sony Xperia P, U, Sola, Go] Alroid:
maybe you're right, did you try it Akki or it's a theory? bcs I remember I read a post (I think by DooMLoRD) about unlocking BL and losing it forever...:confused:

by the way mine is gone and I've not any backup :eek:
[Sony Xperia P, U, Sola, Go] androizers:
Sorry Dude,

But now its of no use once u have Unlocked Your Bootloader...

Its for only those who r willing to Unlock Bootloader for 1st Time or Haven't Unlocked It Ever....

Actually wat happens to our bootloaders is, we have a TA Partition in our fone which contains a entire Private Info of individual's fone....

When v Unlock the bootloader, the TA got deleted or got corrupted ib which v r only left with EMEI n some other private info...

So what v have flashed the Relock Bootloader.ftf is, it contains a loader.sin and Preset.TA (TA Partition)..!

xperia.cz manage to make it Universal which can b flashed on every certain device model to get our Bootloader as well as its status Back to Locked...

But Remember, If v mistakenly Flash someone's TA Partion into our device, the device will surely Hard bricked...

Even if the devices n Model no. r same, then also its going to Hard bricked...

I've never tried bcuz when I came against this method, my Bootloader was already Unlocked... As I mentioned above, This process is for only, who haven't Unlocked Their Bootloader ever...

Just finished my studies :highfive:

first of all I want to thank those who donated today I just checked my email and I was pretty impressed in what I saw (total of 60$), It means a lot to me :')) Thank you :)

to make sure I'm ready for tomorrow I need the kernel log to be able to identify why wifi is doing that issue.

Please on Android terminal (or adb on PC, but first on PC you need to access the shell by executing: adb shell in CMD) execute the following after obtaining SU access:

1. dmesg clear

2. dmesg > /sdcard/dmesg.txt

Before executing the 2nd command please attempt to connect to the network you are failing to connect to and then execute the 2nd command in this way the lines I want from the log should be at the end and not hidden between the lines :cowboy:

Sorry for not participating today :-/

And thank you for your reports :)

[Sony Xperia P, U, Sola, Go] Waledac:
For me Your Kernel is working like a charm no random reboots, no wifi problem ... and AnTuTu Benchmark score of 6739

Till now No Problem :)
[Sony Xperia P, U, Sola, Go] manu_2911:
What's your govenor/IO? I use wheatley/row, but my score only 6666, lower than when i use 7.4 for ICS. Is there any unusual?
[Sony Xperia P, U, Sola, Go] Waledac:
I use Pegasusq/sio
[Sony Xperia P, U, Sola, Go] OmarBizreh:
You would get such thing because I haven't yet updated the linux kernel source code, by updating the source code the following will be achieved:

Better memory management

Better IO handling

Better process management

and some other stuff useful for making kernel lighter

I will be working on updating the source code today hopping by nighttime it will be finished :)

In the mean time use SetCPU or NoFrills (I guess that was it's name) to change the following values

Up Threshold: I set it to 70, this means that once the load on the CPU reaches 70% Frequency will be pushed up (if i'm not mistaken pushed up to max freq.)

Sampling down factor: I set it to 5, I don't really recall it's description but I remember that the higher the value is the less the kernel attempts to lower CPU freq, it's NOT good to set it if you are a gamer, in this case CPU could spend most of it's time at 1GHz while in some parts of the game all it needs is 800MHz

Ignore nice load: I set it to 1, some processes treat them selves as high priority while they don't require such priority, so this will make CPU ignore those processes and serve them only when it has free time or when they need to be served.

Sampling Rate: this defines when to check for CPU load and make decision about raising or lowering frequency, it's value is calculated in micro second, by default if i'm not mistaken it's set to 50000 = 50 mili second, if you are a heavy user lowering the value helps in making CPU raise frequency more often BUT it will lead to losing more battery.

My disciption above may not be 100% accurate you can read more about them by Googling for the xda thread that explains them in details, but playing with these values do make a difference even for stock kernel :)

please note that they might not be available in all governors, but when you find them do the changes that suits your needs.
[Sony Xperia P, U, Sola, Go] CosmicDance:
Hi Deep,

Nice to know about the future tweaks you're gonna apply to the kernel and we're looking forward to it.

As 2 other users earlier noted, the MAC address is changing after every reboot. Maybe you could look into this as this could be one of the main reason for the Wi-Fi bugs. The MAC address should never be changed as it's a signature for a particular hardware...

Thank you again for this wonderful kernel.

Regards,

CD
[Sony Xperia P, U, Sola, Go] ZN6:
This is the main reason why should I unlock my bootloader:D

Will unlock my bootloader once Deep release it. Looking forward for your kernel.

Thanks mate:)

[Sony Xperia P, U, Sola, Go] _nafets_:
I think he is already working on this problem. I send him my dmesg a few hours ago.

In my opinion, the "bug" why wlan is not working is an installed MAC filter on the accesspoint.

Nevertheless a changing MAC address at boot is also unwanted ;)
