Because overclocking needs to be enabled in kernel itself, by raising clock frequencies...
[Xperia Play Android Development] Logseman:
You have a CyanogenMod build with overclocking enabled (for a Tegra2 device) here: http://xdaforums.com/showthread.php?t=1012609

The build maintainer, mad-murdock, is one of the maintainers of the Desire HD builds as well, so you might be interested in asking him about the topic.
[Xperia Play Android Development] Blagus:
I'm sure it comes with custom kernel.

CM7 doesn't actually have the, precisely said, overclocking functions. It just changes frequencies from the list compiled in kernel - custom kernel or kernel module will always be required to overclock the CPU above factory settings.
[Xperia Play Android Development] Logseman:
You're right, I forgot it does come with a custom kernel (Buzzing Bee and Corvus if I recall properly).

Does that imply we will never be able to overclock the Xperia Play?
[Xperia Play Android Development] Nhialor:
He's building the oc module atm...?
[Xperia Play Android Development] Blagus:
We will! That's why I asked for frequencies reported in SetCPU, so I can know what should I look for in kernel source...
[Xperia Play Android Development] SE_iCEQB:
Blagus for president !

What's the maximum in terms of overclocking? I read 1,8 GHz should be possible and still stable, is it true?
[Xperia Play Android Development] Blagus:
I think overvolting is necessary for that high frequency... but I'm getting phone soon, so I'll know everything ;)
[Xperia Play Android Development] svenk919:
Well, it's still working since that post without any problems :D. That's about 22 hours at this moment.
[Xperia Play Android Development] Blagus:
Did you discover any new bugs, except Wi-Fi and camera?
[Xperia Play Android Development] Logseman:
Once the Wifi issue is solved, I'm ready to have this as my daily driver and test it at leisure.
[Xperia Play Android Development] svenk919:
None at all. Only that it can't read ntfs sd cards but I posted that earlier if I recall correctly. Played some music, ran the snes emu and browsed the web/market all without problems. Receiving pushed e-mails works fine. (un)Installing apps works fine.

Will test gps when doing groceries, I'll probably report back in 30 minutes.

Edit: Gps works, it works with only gps satellites, using phone towers and both together.
[Xperia Play Android Development] Blagus:
In next release I'll investigate NTFS issue. Maybe it's not made for SD cards, or simply I accidentally disabled in in kernel config :p

Also, I'm looking at overclocking, and Wi-Fi fixing. Camera is on a small hold until I fix Wi-Fi (it's more important than camera).
[Xperia Play Android Development] Blagus:
alpha2 coming!

Changelog:

* kernel renamed to SEtweak

* NTFS support revised, debugging enabled

* Wi-Fi fixes - still will go through a test before release

* force module loading and versioning disabled (was enabled in alpha0 and alpha1)

* bcm4329 module for Wi-Fi
[Xperia Play Android Development] thomassafca:
Yuy Wi-Fi is working :D
[Xperia Play Android Development] Blagus:
Kernel beta1 uploaded! :D Thanks to Thomas for testing!

Wi-Fi fixed! Thanks to jerpelea for tips!
[Xperia Play Android Development] FrAsErTaG:
downloading and flashing now :D

edit: flashed and wifi working, btw I get away with "fastboot flash boot boot.img" no need for the "–i 0x0fce" YMMV
[Xperia Play Android Development] Blagus:
If anyone can, test NTFS support. Then send me the dmesg:

dmesg > /sdcard/dmesg.txt
[Xperia Play Android Development] FrAsErTaG:
hacked modaco google talk with video constantly force closes... im off to bed will replace with stock gtalk in the morning
[Xperia Play Android Development] svenk919:
Wi-fi works! Will test ntfs soon but making a back-up takes some time...

Edit: Still asks to format the card, root explorer says the sd card isn't mounted.
[Xperia Play Android Development] Blagus:
can you mount it manually? mount -o remount -t ntfs (or ntfs-3g) /sdcard
[Xperia Play Android Development] thomassafca:
How to test that ntfs thing? I got a spare microSD :P
[Xperia Play Android Development] svenk919:
# mount -o remount -t ntfs /sdcard
mount -o remount -t ntfs /sdcard
Usage: mount [-r] [-w] [-o options] [-t type] device directory
# mount -o remount -t ntfs-3g /sdcard
mount -o remount -t ntfs-3g /sdcard
Usage: mount [-r] [-w] [-o options] [-t type] device directory

is what I get :( I'm not a pro with shell commands.
[Xperia Play Android Development] Blagus:
Format whole card in NTFS. Insert in phone. If it isn't mounted properly, use this:

mount -t ntfs /dev/block/mmcblk0p1 /sdcard
[Xperia Play Android Development] thomassafca:
I get this message on phone:

Blank SD card

SD card blank or has unsupported file system.
[Xperia Play Android Development] Blagus:
After trying mount command in adb shell?
[Xperia Play Android Development] thomassafca:
mount -t ntfs /dev/block/mmcblk0p1 /sdcard
mount: No such file or directory
[Xperia Play Android Development] Blagus:
Install busybox from the market first ;)
[Xperia Play Android Development] Blagus:
mount -t ntfs /dev/block/mmcblk0p1 /sdcard
[Xperia Play Android Development] thomassafca:
How to install that if dont have my sdcard mounted? :P
[Xperia Play Android Development] svenk919:
after doing this I can mount the sdcard in settings -> storage -> mount. Root explorer can go into the sdcard but it's read only and when I open this foto i put on to test it loads only a small part of the photo (everything blurry) and then says sdcard isn't mounted.

EDIT: got the dmesg file.
[Xperia Play Android Development] Logseman:
Busybox, as well as any other market app, can be installed in the internal memory ;)

BTW, you don't even let me romance a girl without turning my phone upside down again. Jeez, I have to keep this thread watched :D
[Xperia Play Android Development] Blagus:
beta2-experimental:

* frequencies test, 1024MHz should be 825MHz

*Not working, tested by svenk919*
[Xperia Play Android Development] svenk919:
This one (beta 2-exp, now deleted) makes your screen turned off all the time, don't know if it's working. It's vibrates if you hold the power button to turn it on but then it does nothing( no screen, no indication light it's on etc... Have to remove battery to turn it off again so you can go to fastboot mode.

Flashing beta 1 back with fastboot fixed it :)

Edit: removed warning, to bad OC might take a while :(
[Xperia Play Android Development] Blagus:
OK, thanks for testing. Link and file removed. I think I know what I did wrong, but OC will have to wait until I get the device.
[Xperia Play Android Development] thomassafca:
I flashed my original kernel back, but now Wi-Fi doesn't work :(

Do you where to find the original bcm4329.ko file?
[Xperia Play Android Development] mehmehmen:
everything seems to be working so far havent tried camera yet as was listed as not working. other than that wifi and calls etc all fu nctioning normally
[Xperia Play Android Development] Logseman:
Take it from the System Dump thread. It's in the same folder, of course.
[Xperia Play Android Development] axiomjunglist:
I'm curious if anything in the kernel effects the LMU ambient light sensor. I spent the better half of yesterday changing ownership and permissions of directories associated but none seem to take effect upon applying. I use vi as my terminal editor of choice in adb and :wq! won't even work after editing files, not even with su enabled.

Using lines to modify LMU settings in hw_config doesn't seem to change anything either, even with -rwxrwxrwx applied to the file.

Changing enable from 1 to 0 does something on reboot, but it doesn't completely disable the sensor and it reverts back to 1. I figured altering the curve might do something but I couldn't get the settings to stick. What I was attempting to try was changing group_1 to group_1,255,255,255,255,255,255.

So I guess my question is despite mounting /system in rw mode right off the bat, it doesn't seem to allow anything in /sys/devices/i2c-0/0-0040/leds/lcd-backlight/ and subsequent directories to change. I wonder if the kernel has anything on this.

I figured I would ask those more intimate with the kernel as I've been trying to follow dmsg and not seeing any signs of a (relevant) relationship to the LMU.

Definitely a side issue but for me, this along with OC would be huge. Also, I know nothing about CM7 or if this would be a moot point with the eventual install ;)
[Xperia Play Android Development] Blagus:
I can disable light sensor in kernel, and compile support as kernel module, so if you want it, install module, if don't, leave everything as is ;)
[Xperia Play Android Development] axiomjunglist:
Awesome! So this will be included in the next kernel update then? You rock man!
[Xperia Play Android Development] Blagus:
Yes, it will. I see that light sensor is annoying thing for many people :p
[Xperia Play Android Development] Logseman:
I couldn't try your kernel until today. Obscenely quick boot, not a single lag, most functions working out of the box... this is great.
[Xperia Play Android Development] svenk919:
The light sensor works perfect for me and many people, so don't disable it by default please.
[Xperia Play Android Development] axiomjunglist:
Svenk919 is right, probably better to leave it as is for those who don't have an issue with it.

Would it be possible to create an optional modified kernel extension/module set to disable it for those who want to?
[Xperia Play Android Development] Blagus:
Development will continue next week, as soon as I get the phone. Some internal testing build might appear for a few people to test it, but public beta2 can be expected next week. I'll look into OC and camera, for now it appears that camera is disabled somehow in the sources.
[Xperia Play Android Development] Blagus:
Can someone test NFC with custom kernel? For example, biometric passport.

https://market.android.com/details?id=at.mroland.android.apps.nfctaginfo&feature=also_installed

This app should be able to read most NFC/RFID tags, including biometric passports.
[Xperia Play Android Development] Logseman:
AFAIK the Xperia Play has no NFC...
[Xperia Play Android Development] svenk919:
It seems to have the hardware for nfc but it's not connected, so it should require both a software AND hardware modification. Probably not going to happen.
[Xperia Play Android Development] Blagus:
DAMN! Don't tell me that I have to open this phone to see what's going on with NFC... nobody tried app?
[Xperia Play Android Development] Logseman:
Who has a biometric passport? I've never seen one...
[Xperia Play Android Development] Blagus:
I'm getting it next week :p I have already prepared 10 NFC tags I found in home for scanning :p (NFC/RFID tag is the hard loop on a piece of plastic thing you sometimes can find inside your new jacket).
[Xperia Play Android Development] nscxp2005:
Hi Blagus,

Would it be possible to add Chainfire 3D in to the kernel or would we just have to download it instead?

Keep up the fantastic work
[Xperia Play Android Development] Blagus:
did you try it on custom kernel already?
[Xperia Play Android Development] Logseman:
CF3D works on your custom kernel.

Oh, and I forgot to add: Backstab has sound now, contrary to the alpha build :D
[Xperia Play Android Development] nscxp2005:
Hi Blagus,

Sorry for asking. I am getting an Play in November when I upgrade. I just wanted to know for future reference.

Logseman, how do games perform with Chainfire? Especially Tegra games?
[Xperia Play Android Development] Logseman:
I haven't tried the Tegra-spoofing plugin, but the games I've tried run better with than without CF3D, at least marginally.
[Xperia Play Android Development] TheBassman369:
I can second this.
[Xperia Play Android Development] nscxp2005:
Thank you for the quick response.

I look forward to getting mine and trying all this development on it.

Keep up the great work guys!
[Xperia Play Android Development] Nhialor:
What's the kernel version of this?

2.6.32.9-001?
[Xperia Play Android Development] Blagus:
2.6.32.9-SEtweak
[Xperia Play Android Development] Nhialor:
Is this pre-built into the CM7 build Beta 1? Cause in the about phone it says my kernel is 2.6.32.9-002 not -SETweak
[Xperia Play Android Development] svenk919:
I think cm7 uses a newer version of this kernel or uses parts of it. But since I don't really need the extra 50% cpu power and the kernel with cm7 gave me some trouble with my sd card I prefer the SETweak kernel.
[Xperia Play Android Development] teckhwee:
Is auto brightness disabled?
[Xperia Play Android Development] Nhialor:
Yeah I think the auto brightness is disabled. I'm using cm7 here with their kernel, trying to find out which is better, that or this.
[Xperia Play Android Development] FrAsErTaG:
Hey Blagus

Hope you are having a good holiday

are you looking at enabling the fm radio? I am lead to believe the device has a functional fm radio, much like the nexus one it has the hardware but not the software or kernel support.
[Xperia Play Android Development] Blagus:
finally found wifi here :P

i'll see with rest of freexperia. nfc is also present in sources but incomplete.
[Xperia Play Android Development] Nhialor:
How do you flash this? Flashtool doesn't recognise my phone when it's connected...says please connect xperia.

I've connected when in recovery and normally, dunno what's happening?
[Xperia Play Android Development] FrAsErTaG:
you

should

be able to flash the stock kernel via fastboot I have it in my patches section of my thread
[Xperia Play Android Development] Nhialor:
flashed back to stock kernel, and when I turn my phone on it says, safe to remove sd card, i remove it and put it back in and it gives me the same error. How do I fix this?
[Xperia Play Android Development] svenk919:
That was a problem with the first costum kernel. Are you sure you flashed the stock kernel? This one should work: http://xdaforums.com/showpost.php?p=14821537&postcount=17 flash it with flashtool and it should only install the stock kernel and loader.
[Xperia Play Android Development] Blagus:
Camera hopefully fixed - sensors were disabled in config all the time, I can't believe how I missed it.

Also, OC from if2's Arc kernel added.

Wi-Fi bcm4329 driver included in kernel - please, remove module from /system and reboot, report if wi-fi works that way.

CPU idle state enabled.

http://www.mediafire.com/file/jq87btr4f0dyy21/SEtweak-RC0.zip
[Xperia Play Android Development] Blagus:
Would you like tun and cifs to be included in kernel?
[Xperia Play Android Development] :
Hi,

I'm an Nexus S owner and I have a question. Do you compiled the driver for USB OTG by yourself?
[Xperia Play Android Development] Logseman:
I don't think the Wifi module can be inserted on the kernel. According to apache14, best known as BumbleDroid, a quite renowned kernel dev for HTC devices and Advent Vega, Wifi being dependent on a module is a requirement of the OS.
[Xperia Play Android Development] svenk919:
OC and camera confirmed working, no time for the wifi though :(
[Xperia Play Android Development] Blagus:
can you try this one.to confirm?
[Xperia Play Android Development] Blagus:
it was a part of kernel. you just have to enable it in kernel config.
[Xperia Play Android Development] :
Is there any chance to port this to the Nexus S?
[Xperia Play Android Development] _terror_:
I got 5 questions for you guys.

1. How do i know if i've unlocked bootloader or not?

2. Can't i do this if my phone already is rooted?

3. Do I have to do a fresh re-install? (lose all my apps ect)

4. Is it really worth it? Do you REALLY feel a big difference?

5. Is battery life a big problem after? Do you feel any big difference?

Thanks!
[Xperia Play Android Development] Aerox912:
1. If you flashed a custom kernel or rom/system image before, then you are unlocked. And since you are rooted i suppose you have (or did u use gingerbreak?). Check this link, if you did that, then you are unlocked.

2. Doesn't matter if you are already rooted i suppose, can't see why that should be a problem.

3. No, kernel update leave's your user data and system intact. Only the kernel gets updated. All your data is safe.

4. Thats for you to decide, Really feel a big difference, not really a big difference, but things will go a bit smoother, and maybe a little bit fps gain in emulators, have not tested that so i can't confirm that.

5. depend on usage, if you run at 1,5ghz al the time, then yes your battery life will be a problem, but if you use it on demand with setCPU or CPUmaster. then you will be fine, i think. you can always easily flash back if it is a problem to you.
[Xperia Play Android Development] _terror_:
First of, thanks for the great respond. Have some more q for yah :)

1. Yes i used gingerbreak, does that mean i'm unlocked and good to go?

2. Ok

3. Oh, so my games and spec my saved games for like zelda won't get deleted?

4. Ah, okay

5. I see. well, that sounds logic
[Xperia Play Android Development] Logseman:
It's a no-go. When I try to connect from the Settings menu, I get the "Error" message which indicates a problem with the module.
[Xperia Play Android Development] Nhialor:
yes to cif and tun
[Xperia Play Android Development] Aerox912:
Hmm,

Since u used gingerbreak, when you were on 2.3.2 i suppose, i think you don't have an unlocked boot loader.. So no your not good to go ;)

Cause most people flashed a custom rom image which is pre rooted. (for that you need a unlocked boot loader.

The guide i linked to in my previous post, did u follow that in the beginning before rooting? cause if you didn't follow that guide, or any other guide and you never requested a unlock key from sony, go to this site and see if you recognize it.

If you did not follow these steps, then you are still locked.

And if you are still locked, that means that if you want to unlock, you will lose all you data..

But... you are already rooted, so first thing you should do is backup all you data with Titanium backup (market link), because you can do that if you are rooted.

In titanium go to backup/restore > menu > batch > backup all user data (or all user data and system data, but i never restore system data, due to compatibility issues if you for example flash back and forth to Cyanogenmod and normal Xperia play rome)

After backing up all your data it is totally safe to flash new kernels, roms, whatever with an unlocked boot loader. But keep in mind, never to do OTA (over the air update, settings > about > software update) if your boot loader is unlocked, that will brick your device and then you need to unbrick it.

It's not that hard, but you want to avoid that ;)

And about your games, like zelda, thats in an emulator i assume. Thats always safe because emulators save data on your microSD by default.

Just like all the gameloft games, also saved on your microSD.

Only game i fail to recover user data is worms (not that big of a deal :p)

Ow and wifi is not working in this kernel for the time being, but thats only a matter of time :)

So in this order > backup!! > unlock boot loader > restore app + data > flash kernel, and everything will be fine.

Hope this answers all your questions.
[Xperia Play Android Development] _terror_:
Wow, thank you so much! That was really helpfull! I just need to find the courage to do it. It seems like it's much work and pretty hard to do it to :P

How long do you think it will take before you got supported WIFI? 1 week, 1 month or maybe 6 months? If you have to take a guess.
[Xperia Play Android Development] Aerox912:
I't not much work at all, only thing that takes about 15/20 minutes is backing up everything. Unlocking boot loader is 5 minutes at maximum. And it's just following the steps described in the link in my previous post, it's the original page from sony for unlocking the boot loader. Nothing hard there. if you find any difficulties you can also check the thread here on first page about rooting/unlocking your play. everything you need to know is in there. link

Just make sure to type in the right imei code and copy paste al the command's ;) piece of cake.

We'll i'm not the developer (wish i was :p), so that i can't answer for you. Blagus is doing his best he can, so he will update it with wifi when he figures out how to i guess.
[Xperia Play Android Development] _terror_:
ok cool! :) will try it out as soon as the wifi works :)
[Xperia Play Android Development] Blagus:
coming in next few days:

restore wifi to module.

tun and cifs

and kernel can finally go to stable release 1.0
[Xperia Play Android Development] Neodreamer24:
Thanks for your job. Waiting for wifi fix.

Why it works in beta 1 and not in this new version?

Thanks
[Xperia Play Android Development] Blagus:
It was a experiment. Kernel is now ready and it's in testing phase. It will be released tomorrow.

Features:

* tun, cifs

* OC up to 1,86GHz

* CPU idle state

* autoroot

* insecure adb shell

* ext4

* NTFS

* USB OTG
[Xperia Play Android Development] Logseman:
Once that you actually have the phone in your hands, what's your opinion about it?
[Xperia Play Android Development] Deblow:
If my play is rooted and still on 2.3.2 but is locked to orange network ,

is there anyway i could get this to work?
[Xperia Play Android Development] Logseman:
No, there's not. This kernel only works for devices with unlocked bootloaders, and network-locked devices like yours can not have their bootloaders unlocked.
[Xperia Play Android Development] thatsupnow:
How come we can't flash the kernel with flashtool like the X10 gingerbread kernel?

They don't have unlocked bootloader

Sent thru the air!
[Xperia Play Android Development] Deblow:
Thats not good :(

thanks for letting me know...

guess i will update to 2.3.3
[Xperia Play Android Development] Logseman:
Flashtool doesn't need open bootloaders to work. It's Fastboot which does.
[Xperia Play Android Development] Laberkopf:
I just wonder about why you compiled ntfs support in. Imho that does not make much sense
[Xperia Play Android Development] Logseman:
Probably because of the USB host capability. Many external HDD's have the NTFS format.
[Xperia Play Android Development] nscxp2005:
Logseman,

Does that mean we card format our SD cards as NTFS or does it mean we can connect a External HDD to the phone ?

I was wondering myself what the NTFS support was for.

All the best,

NSCXP2005
[Xperia Play Android Development] Blagus:
It's big compared to X8 :p and screen is great... especially after removing that ultraglued screen ****, oops, protector...

But it has extremely long bootup time...

It uses splboot method to load custom spl which loads new kernel. New Xperias have accessible boot partition so spl method is not modified for these devices.

Mainly because I can :p and if you want files bigger than 4GB on your phone you need NTFS (if you want to watch HD movies), and because OTG is enabled and many external HDDs have NTFS (like Logseman said).
[Xperia Play Android Development] nscxp2005:
Blagus,

What sort of things can we do with USB OTG?

Thank you for your time.

All the best.

NSCXP2005
[Xperia Play Android Development] Blagus:
OTG makes your phone a host for USB devices, it means you can connect USB devices to be used by your phone, like USB Flash drive, USB HDD, etc.

BTW kernel is done. Will be uploaded soon ;)
[Xperia Play Android Development] nscxp2005:
That sounds so cool. Do we need a special cable to use such USB Devices?

Excellent work Blagus!
[Xperia Play Android Development] Blagus:
Yes, it's USB OTG cable which has usual micro-USB on one side and female USB on the other side.
[Xperia Play Android Development] Blagus:
Just great. SE released new kernel sources. I'll update to these and release new kernel then, so be a bit patient :)
[Xperia Play Android Development] DooMLoRD:
