[KERNEL]░█░ Jeffrey-SpeedFrey 3.0.0 ░█░ Amazing battery life(!) & more (Update 21/08)

Mod Edit - Thread closed while under investigation

Hello guys,


It's my kernel for the SGS II.



I am very surprised with the battery life.

With my own experience (with Batista ROM, the best for me): The battery is still 100% after 8 hours sleep (wifi ON, data ON) :eek: :eek:

The kernel works very great. Stable, fast, no reboot or freeze. Tested with some roms. Stress test successfully done without reboot or freeze.

The kernel has these frequencies: 1204 / 1150 / 1100 / 1000 / 800 / 500 / 200 mhz. Compatible with SetCPU (auto detect).




IMPORTANT

For versions 2.2.0 and lower : there are 3 versions. Release Version, Workaround Version and Stock Voltage Version.

For versions 3.0.0 and higher : there are 2 versions. Release Version and Workaround Version.

Try only Workaround Version or Stock Voltage Version if you have issues with Release Version.

You can install this kernel with Odin (in PDA) or CWM Zip installer (since 2.1.0).

AFTER the kernel has been flashed please calibrate your battery.




My goal: Battery life and Optimization. :cool:

More optimizations and options in the future. Kernel continuously updated.



Jeffrey-SpeedFrey_Kernel 3.0.0​

This kernel is optimized and uses low ram. The boot is very fast and everything is very smooth and fast.

Impressive battery life while using your mobile phone.​

FEATURES (for more details, look changelog) :

  • Undervolted (CPU and GPU) (not compatible with the SETCPU control voltage because the kernel is optimized with my own values)
  • Workaround version available (less undervolted)
  • Stock voltage version available
  • SetCPU compatible (1204/1150/1100/1000/800/500/200 mhz)
  • BFQ-V2 Scheduler added and set by default
  • 838 MB ram memory available
  • CIFS support (cifs.ko and slow-work.ko automatically integrated in "/lib/modules")
  • BLN support
  • Vitalij's touchscreen fix (value : 10)
  • Rooted
  • CWM 4.0.1.4
  • Interactive governor
  • Disable some debugging options / look changelog (better battery life, better ram usage and smoothness)
  • Some tweaks / look changelog (better battery life, better ram usage and smoothness)
  • Initd.d support
  • I/O scheduler tweaks
  • Low ram usage
  • Optimized for battery life



Changelog 3.0.0 :

  • SetCPU compatible (1204/1150/1100/1000/800/500/200 mhz)
  • BFQ-V2 Scheduler added and set by default
  • 838 MB ram memory available
    1128603088.00png
  • Increased smoothness with ram optimization
  • Increased battery life when the phone is on sleep with cpufreq.c optimization
  • Disabled Config_bugverbose (more memory, better smoothness and better battery life)
  • Disabled Bug() (optimize memory usage, better smoothness and better battery life)
  • Unnecessary developer options disabled (optimize memory usage)
  • General optimization for battery life
  • Thanks to all beta testers

At the bottom of the page screenshots of stability test.

Try only Workaround Version or Stock Voltage Version if you have issues with Release Version.

Nice to have another Kernel Dev on board! I'll give your Kernel a try, will post results later on! :)

EDIT:

Correct me if I'm wrong, but this one seems to be based on the t18b-Speedmod-Kernel by Hardcore! At least this is was the Kernel-Info says! You should mention that in your OP!!

    Tried : Jeffrey-SpeedFrey_Kernel1.0.0uV-x3 (Extreme Edition 3) Amazing battery life

    Am running the latest SolarFlare ROM.

    Flashed with ODIN as a PDA file.

    Booted fine ... a few minutes later.. stuck ... .. the phone/screen/buttons unresponsive ...

    flashing the x2 version now .. will report back how it goes .

    The x3 version depends on the mobile phone(SGS II). You need to have a bit of luck with this version :)

    Only for the initramfs (cwm 4.0.1.4 and root !) but not the kernel it's from official samsung (update1) and modify by me !

    Tried the x2 ...

    Still hangs after a few minutes


    Tried the x1 ....

    Hung and Screen black as soon as an SMS came in ... perhaps something to do with BLN because I see the softkey lights still on.

    hmmm



    Which rom do you use? Maybe your phone don't like the under voltage....

    Freezy on cog 1.31, so many attempts also are failing, disabled setcpu(even uninstalled it), but still fails.

    Might be some other trick is required!

    No luck for 1x to 3x.............

    - freeze on first few min (2x & 3x)
    - Sleep to dead (1x)

    back to Speedmod............

    P.S. Using Cognition S2 v1.31

      Source Code?

      Please post your source code

      Looking for these too.

      I'd like to request kernel sources?

      I appreciate your effort trying to answer everyone their questions in this thread besides the most important one.

      So I guess I'll request it again.

      Kernel sources please?

      At risk of sounding redundant....POST YOUR DAMN SOURCE CODE THE GPL ISN'T JUST THERE FOR BEDTIME READING.

      If you did take something from hardcore, at least have the courtesy of mentioning him...


      I mentioned!
