Sure I wili ladd it to the first post :)
So far you need to flash the kernel via Fastboot by executing this command:
fastboot flash boot boot.img (if you are using test 1)
fastboot flash boot boot_Test2.img (if yo uare using test 2)

No my friend, root doesn't enable you to flash a custom kernel.
You must unlock your bootloader.
Rooting is a different process.
This kernel roots the phone (if using test 2) so don't worry about root :)

I had recovery preinstalled :/
After fastbooting kernel recovery is still working

Re: [Kernel][Sony Xperia U][March - 21] Sliding_XU [Stock]

Battery life is so far good.... A bit better than stock... Not extremely better ( miracles dun happen overnight ;) )
Nt experiencing lags... Games running smooth (temple run 2 and shadowgun tested, I have just these 2 :/... Nenamark 2 is 29fps ( max for stock I guess)
Antutu 7200(+-100)

M nt a fan of benchmarks bt performance is smooth overall

Since this kernel is compiled from source... It has almost equaled the stock kernel wid additional features
In the very first release

Great job ...... :)

Re: [Kernel][Sony Xperia U][March - 21] Sliding_XU [Stock]

I had seen the kernel for Xperia P and marveled at the number of satisfied users, and was hoping you'd make one for us... And voila!! Thanks a lot, bro.

I'm current on CM, and will wait for the CM version.
Thanks a lot. :thumbup:

To be honest I can't confirm anything because I don't have the device, my expectations are based on what I've seen on my Xperia P before it got bricked and also building my expectations on what users will report.
So you will have to try it out your self and if it doesn't work you can simply flash back a different kernel to make your device boot again :)

    Version 4 (Stock ONLY) Change Log
    • ICS kernel links for CM9.1 & Stock included in Download section of this post.
    • v4 is for Stock JellyBean ONLY. v3.x & v2 are for ICS ONLY
    • Based on FXP source code for CM10
    • All features of ICS kernel included
    • All Governors & IO Schedulers of ICS kernel also included (maybe I missed on or two, but the important ones are there :) )
    • irq: Set CPU affinity as soon as the irq thread is created [1]
    • ARM: decompressor: Enable unaligned memory access for v6 and above [2]
    ------------------------------------------------------------------------------------------------------
    Explanation for [1] & [2]
    • [1] In an embedded target where IRQ affinities are pre-configured during
      boot-time (and not modified through /proc/irq/../smp_affinity) during
      run-time, the extra latency due to irq_thread_check_affinity can be
      avoided during processing of the first interrupt with this patch.

    • [2] Modern GCC can generate code which makes use of the CPU's native
      unaligned memory access capabilities. This is useful for the C
      decompressor implementations used for unpacking compressed kernels.

      This patch disables alignment faults and enables the v6 unaligned
      access model on CPUs which support these features (i.e., v6 and
      later), allowing full unaligned access support for C code in the
      decompressor.

      The decompressor C code must not be built to assume that unaligned
      access works if support for v5 or older platforms is included in
      the kernel.

      For correct code generation, C decompressor code must always use
      the get_unaligned and put_unaligned accessors when dealing with
      unaligned pointers, regardless of this patch.

    Then there is an issue in the source code, because the last test I gave to you was v3.3 and you reported same results.
    I will try to port Xperia P source code my self, cuz I've used both the one that was posted here and the one that was posted on Sola forum and got the same results. will need some time though :-/
    Or I might just use another kernel source code to save time, porting it my self with the little time I have will take long time.

    Edit:
    No worries no matter what I will make a kernel for Jelly Bean roms :)
    Just be patient and I'm sorry for all the trouble I caused :)
    Thank you.
