Thanks!

Flashed kernel a few minutes ago, looking good so far. I'm using smartassv2 governor and deadline scheduler, no overclock.
Hopefully there won't be any bugs to report :)


Just one thing: it would probably be a good idea to post stock WiFi modules, for those folks that may want to go back from your kernel to the stock one.

Aaargh... scratch that, there are some issues with the new governors:
Scrolling in LauncherPro (between screens, in the app drawer) is jerky. Also in Pulse News and Pocket (ReadItLater), although not as bad as with the launcher.

It's the same for smartassv2, minmax, interactive.
Ondemand and performance are fine, smartass (not v2) is a bit better but still laggy.

Also, the device is slow to wake up, with any governor: takes about 2-3sec for the screen to turn on, after pressing the power button.


EDIT- forgot to mention, I'm running KA02 ROM... there may be conflicts with one of the init.d scripts that come with the ROM.
Would appreciate it if anyone running stock firmware would test the kernel and report back.

The new governors just aren't optimized yet for new Xperia devices ;)

It has nothing to do with the tweaks, but I can try to add some specific tweaks for the new governors, it might help :)

Choice is good, but so many governors? I am no expert on this matter, which is exactly my point. Someone with a good understanding on how governors work should add options for, say, three scenario's:
- Performance. When needed, throttle to max. overclocked speed and switch to faster speeds sooner
- Medium, scenario between energy saving and performance.
- Energysaving. Do not overclock, set the clock the lowest setting possible when screen off, sleep mode and use moderate throttling just enough to ensure the device doesn't feel laggy but isn't as snappy as Performance.

Or.. post the settings for these scenario's here :)

Awesome work guys!

Just a couple of days of struggling with study, and then I''ll finally have some time to experiment with the phone. Hopefully this new kernel will allow a nice improvement in battery life :)

    Hi all,

    After a long time it is finally time for an update.
    I started working on the new .54 sources and added upstream changes till Linux 3.0.60
    Also i added all cm fixes, and updated some governess for the u8500 soc.
    Also i have added sound boost, which SHOULD boost the sound a bit And of course a lot of other fixes.

    Currently i am testing the kernel to make sure there aren't problems


    edit: all tests went fine, will add some last changes and upload it for you guys
