hardcore schrieb:

Hi guys,

This is the SpeedMod kernel for the Samsung Galaxy S2 GT-I9100.

SpeedMod's core features are:
- Super stable: No undervolting, overclocking or potentially unstable modifications
- Fast and smooth: Compiler and code optimizations
- Excellent battery life: Remove unecessary logging and debugging

WARNING: This kernel does NOT work on the GT-I9100G. GT-I9100 ROMs and kernels are not compatible with GT-I9100G.

Current features:

Root and CWM:
- Automatically installs root (su)
- CWM recovery

Screen and misc tweaks:
- MDNIE screen sharpness tuning (improves text readability)
- MDNIE color tuning (reduces over-saturation of color)
- Lower brightness at low-light levels
- init.d, TUN, CIFS, IPV6 Privacy support

Performance:
- CPU governor tweaks: increase responsiveness
- IO tweaks
- Read ahead tweaks
- Updated to jhash3
- Compiled with optimizations using Linaro GCC 4.5 toolchain
- Switched to SLAB instead of SLUB
- Enabled CONFIG_RCU_FAST_NO_HZ

Turned off unnecessary logging for better smoothness and efficiency:
- Disabled Android Debug Logger / logcat
- Disabled Kernel debug
- Disabled Samsung debug
- Disabled CONFIG_FTRACE

More features will be added along the way.

Latest changes:

K2-1:
- Rebuilt using newer AT&T SGH-I777_Opensource source code

K2-2:
- Rebuilt using newer Linaro 2011.10 GCC 4.5 toolchain
- USB charging speed increased by 10%: current limit set to 500mA

K2-3:
- Revert faster USB charging speed, it was causing instability for some USB ports
- Disable Mali-400 GPU state tracking
- Minor bugfix to Exynos cpu suspend hotplug

K2-5:
- Rebuilt using new GT-I9100_OpenSource_Update3 source code

K2-6:
- Change to CONFIG_PREEMPT_VOLUNTARY for kernel (should have less overhead)

K2-7:
- Implemented ARM_ERRATA_743622, ext4 and mm patches from GT-N7000 sources

K2-8:
- Patched net usb drivers from GT-N7000 sources
- Revert to using CONFIG_PREEMPT
- New compiler optimization settings (smoother!)

K2-9:
- Removed -ffast-math from compiler optimizations

K2-10:
- Reworked patches from GT-N7000 sources
- Adjusted init.d script startup delay

K2-11:
- Updated wifi driver from GT-N7000 sources
- Updated CWM recovery to 4.0.1.5
- Changed some compiler optimization settings

K2-12:
- Changed some compiler optimization settings

K2-13:
- Disabled debugging: FRAME_POINTERS and ARM_UNWIND
- Modified IO tweaks (write flush timing)
- max17042: Fix fuel alert wakelocks (thanks Entropy512)

K2-15:
- Added TCP timeout tweaks

K2-16:
- Touchscreen tweaks: MOVHYST ("Vitalij fix") set to 3 (same as SGS1)
- Touchscreen sensitivity (burst length) increased

K2-18:
- Patch from Linaro to support ARM CPU topology
- Updated ARM topology patches
- Enabled sched_mc for dual-core power management
- Enabled AFTR (ARM off top running) CPU idle mode
- Nicer looking kernel version string
- Updated to CWM5
- VM patches from 2.6.36 kernel
- PREEMPT_VOLUNTARY mode
- CPU hotplug optimizations
- Disabled scheduler stats
- Disabled more debug code: STACKTRACE and LATENCYTOP
- High resolution timer HRTICK enabled in CFS scheduler
- Scheduler tweaks
- Some kernel config option cleanups
- Adjustments to compiler options
- Adjustment to wifi driver wakelock timeout
- max17042: Fix fuel alert wakelocks
- nohz: sched delay going tickless when CPU is loaded
- rcu: remove rcu_needs_cpu_flush() to avoid false quiescent states
- remove the per cpu tick skew
- Touchscreen MOVHYST ("Vitalij fix") set to 10

[HOW TO ENABLE LOGCAT]

If you are a developer or want to re-enable logcat for whatever reason, do this:

adb shell
su
mount -o remount,rw /system
echo ANDROIDLOGGER >> /system/etc/tweaks.conf
mount -o remount,ro /system

Reboot and you should have it enabled.

Beim S1 gab es den Voodoo Colour& Sharpness Fix.
Das Bild wurde dadurch wesentlich schärfer, die Schrift wirkte z.B. nicht mehr so ausgefranst!
Außerdem wirkten die Farben nicht mehr so Bonbon-haft.
Und Voodoo Sound war ebenfalls mit dabei!
Als Gingerbread kam gab es das zuerst nicht. Mein Display kam mir total verwaschen vor.

Als es dann kam und ich es wieder drauf gemacht hatte, habe ich die ersten Tage immer wieder auf mein Display geguckt, weil es echt ein großer Unterschied war.

Man kann das Display besser machen indem man die HW besser ansteuert! Ich habe damals z.B. rausgefunden das mein Display eher mehr blaue Anteile hatte, also habe ich auf "warm" gestellt, für mehr rot.
Lasst euch überraschen.

Würde das jetzt auch gerne probieren, habe aber keine Lust extra auf 2.3.3 zu gehen.
Aber bald wird das ja auch für 2.3.4 verfügbar sein.
Dann steige ich sofort um.

Hä ^^ Wie kann das sein, dass bei dir kein Android OS angzeigt wird? xD Ich hatte bisher bei jeder Firmware das Android OS als Prozess.
