Francos idea for a kernel is pretty simple, focus on performance while not sacrificing the battery, and doing this without adding lots of crap code to the kernel or patches
* Initramfs with the usual stuff (root, CWM support, recovery etc)
* Partitions properly mounted in the ramdisk to take the most out from the device
* VM values tweaked up for maximum performance/battery
* Ondemand governor properly tweaked - features 10k sampling rate for more fine grained samplings
* CPU frequency transition latency decreased to 40k instead of stock 100k
* I/O boosted - I feel this is the most important setting in the Android kernels
* CFQ I/O scheduler by default - most of the Android kernel devs choose to work with deadline or other schedulers, but after deep testing a proper tweaked CFQ for flash devices proved me as the most reliable choice
* CFS task scheduler properly tweaked for the best multi-tasking experience
* CFS Autogroup added
* TCP Veno congestion scheduler by default as its more suitable for this kind of devices
* Kernel stripped of debug shit - the only debugs that stayed were: logcat, printk and kallysms (for Voodoo Louder support)
* Patched up to 2.6.35.13 from the mainline kernel channel
* CRC32 library that is used by a lot of internal kernel mechanics completely patched up to the latest versions
* Compiled with Tree RCU Fast No Hz for further battery savings
* The usual Franco's magic
* SLQB memory allocator
* Lots lots more that I will remember later and add it back here...
Changelog:
#2
* Conservative set as the default governor - gave it 10k sampling rate like I did on Ondemand and gave it a 80 up_threshold, a bit lower than the stock value. This will make the governor scale up a bit more often, making the system a lot snappier while maintaining a good battery balance
* Added SLQB memory allocator - I usually tend to use SLUB, but I decided to give this one a try this time and it proved to be a great choice
* Dynamic Hotplug disabled - we want the system to have both cores always enabled. This means two things, means it will help a lot for the race-to-idle (the fast we go into idle the more battery we can save), and it means the amount of overhead that was created during onlining/offlining cpu1 is gone since hotplug is a very costly process to the system
* Power Management patches from the mainline kernel
* EXT4 driver patched up a little bit
* EXT4 write performance regression fixed (regression is when a newer introduced code fucks up, unintentionally, some other code, in this case the regression was fixed)
* Lowmemorykiller driver patched up for a better memory management
* Sleep of death issue should be fixed
* Introduced VMAP_AREA_CACHE - for more information visit this old commit from me
#3
* Patched 2.6.35.14
* Add RWSEM algorithm
* Add CIFS and TUN as modules to /lib/modules/
* Add MDNIE tweaks from SpeedMod
* Remove MALI tracking/debug (increased 1 fps on Nenamark 2 with this disabled)
* Some other small tweaks and optimizations
#3.1
* Sleep of death fix and smooth scaling - I previously had patched the wrong file. cpufreq.c is not compiled for
this device since it has CONFIG_S5PV310_HI_ARMCLK_THAN_1_2GHZ defined
in the config. Thanks garyd9 for pointing that out to me.
#4
* Nothing is changed besides the kernel version number - the application didn't like the .X subversion naming
#5
* MDNIE tweaks removed - they caused bad screen sharpness and weird colors.
* Ondemand default again and tuned for a better performance/battery experience
* Revert RWSEM algorithm patch - just for safety precautions
* Sleep of death should be fixed now (I hope
)
* Reverted 2.6.35.14 as well
* Increased USB charging power - not it charges as fast as on the wall charger
* GPU clocks changed a bit - now minimum clock is 200mhz(up from 166mhz), 2nd clock is 266mhz and third clock is 300mhz
* Some minor tweaks and optimizations in hope for the same battery life as #2 =)
#6
* Completely rebase of the kernel - kernel source is back to 2.6.35.7 and it will stay like that as I don't want mainline kernel patches to fuck up code like there was no tomorrow.
* Kernel rebase also means that I was a lot more careful when choosing the code that I wanted to add which means: more performance, better battery and more stability
* Ondemand is the default governor
* Deadline is the default IO scheduler (for testing purposes)
* GPU clocks are 200min and 267max
* USB charging as fast as the wall charger
* Kernel is clean like a baby's wiped up ass
#7
* GPU max frequency increased from 267mhz to 400mhz
* Ondemand patched up a little bit - use system workqueues and removed deprecated code
* Fixed fuel_gauge wakelock
* Compiled with arch specific compiling flags
* Added a reasonably big patch to fix some CONFIG_NO_HZ issues - battery improvement
* CFS parameters changed a little bit as well
#8
* #7 Ondemand patches reverted
* Ondemand tuned for battery - it only ramps up if load is > 98% instead of 60% like it was before
* GPU clock decreased to 300mhz from 400mhz
* Proportional Rate Reduction for TCP from Google - should improve internet speed
* Removed the config option that skips loops per jiffy calculation - now both cores run with the same loops per jiffy value as it's should be
* Added jRCU and made it default for testing purposes
* Some small tweaks and optimizations
#9
* jRCU removed
* Tree Preempt RCU by default
* Revert TCP patch from Google to ensure stability
* Remove GPU overclock - I want stability and no crashes or pixelated screens
* Tuned up few parameters on the ramdisk
#10 (der letzte Franco Kernel für Gingerbread)
* Complete rebase from the newer Samsung's source
* Applied all previous patches that can be seen from my repo
* Stable, fast, reliable and awesome battery life

Hatte man vorher andere Kernels, Thunderbolt Scripts oder "Zeugs" aus Custom ROM's, ... weg damit.
- Zuerst eventuelle Profile von Set CPU, Voltage Control oder ... deaktivieren, damit sie beim Boot nicht geladen werden
- Kernel Downloaden und auf die SD Karte kopieren
- jBroid Kernel Cleaning laden, auf die SD Karte kopieren und im Recovery (nicht über das CWM App) flashen
- Im Recovery bleiben und den Kernel Flashen (install zip from...)
- Reboot und fertig.
