changelog 25.07.2012:

- updated recovery (no "sdcard format"-bug anymore, external sd card is named correctly)

- vibrant: hopefully fixed froyo ril

- jellybean: galaxy s settings working now

changelog 22.07.2012:

- updated kernal base to linux 3.0.36

- updated "block" to linux 3.3

- readded fiops io scheduler (kept cfq this time)

- updated cwm recovery to 6.0.1.0 (please create a new nandroid, because of possible incompatibilities between old/new recovery)

- compiled with linaro toolchain (gcc 4.7.1) and O3 compiler flags

- made uksm scan less often (save cpu time and power)

- at first boot: only delte init.d scripts created by other kernels

- increased usb write performance

- lowered ram and display voltages a little bit

- fixed some bugs related to devil settings (they should stick now after reboot, if set by one of the devil apps)

- support for scripts in /system/etc/shutdown.d (thx to Efpophis)

- disabled some debugging options

- audio (and for fascinate: camera fixes) by Efpophis+

- patch for improving batterie life by CML

- nfts read/write driver built in (for use with usb host mode)

- reverted refreshrate_mod and gpu_oc mod, as both weren't working :(

changelog 18.06.2012:

- some changes to load balancing

- added ultra ksm (metioned by zach :) thx for this my friend)

- readded fiops io scheduler (still experimental and could cause instablilities)

- using snappy compression for zram now (2 times faster, but only 2% less compression)

- added the possibility to change zram size (at /data/local/devil/zram_size, with valid values: 50, 75, 100 and 150 (all in mb))

- fixed the applying of user_min/max freq after reboot

- vibrant: fixed gps

- fascinate: fixed nandroid in cwm recovery

what is ksm? http://en.wikipedia.org/wiki/Kernel_SamePage_Merging_(KSM)

uksm is more optimized and also working for single core systems. using this should give much better ram usage, but at the cost of more cpu usage

############# most probably not working (yet)##############

i have added seperate gpu oc from jt1134's galaxy_tab (to switch between 200 and 250 mhz), but i did not get any improvements in antutu...further tests needed

echo 1 > /sys/kernel/pvr_oc/pvr_oc (for 250 mhz)

echo 0 > /sys/kernel/pvr_oc/pvr_oc (for 200 mhz), no reboot needed

and also have changend default screen refreshrate from 60 to 56, with the possibility to change it:

echo 1 > /sys/kernel/refreshrate/enable (60 hz)

echo 0 > /sys/kernel/refreshrate/enable (56 hz)

changelog 01.05.2012:

- all changes from cm9 stock kernel (including mount points option)

- some fine tuning to deadline and sio

- Devil Idle: limiting bus/ram/gpu speed to 100 mhz for 100-800 mhz cpu freq, while screen off (automatic mode) or always (permanet), both modes automatically reduce the int voltages of the affected freq by 50 mV

- compiled with swap support

- added stratosk's smooth_ui to lulzactive governor (activated by default)

- rest oc_value to 100 while screen off, and back when screen turns on (combined with devil idle automatic, can't be turn on/off without devil idle)

- added posibility for different voltages while screen off (also bundled with devil_idle, with default settings, stock arm voltages are applied, because of live_oc set to 100)

- added the possibility to set freq limits while screen off (min and max freq)

19.04.2012

- even better fix to selective live_oc (last one (in test kernel) generated some overhead)

- fixed sampling rate of ondemand and conservative (have ported mialwe's/stratosk's sleep multipliers)

- new tunables for ondemand and conservativ

sleep multiplier and tunables:

mialwe and stratosk had the great idea, to change the sampling rate of conservative and ondemand governor while display of. for this, he introduced the sleepmultiplier (in his case factor 3). this means, if you set sampling rate to 20000, it changes to 60000 while screen off, and back, when screen on.

for ondemand and conservative:

i have made this multipliers tunable. proper values are between 1 and 5, because one could want a higher multiplier while screen off, if sampling rate is very low while screen on (higher sampling rate means, less checking for work load --> better batterie, worse performance). with this tunables you get better batterie, without making the performance worse while screen on.

two other tunables: up_threshold_min_freq and responsiveness_freq

the first one is a very low threshold while on low freq (by default 40), to make the governor scale up faster, until the responsiveness_freq is reached.

the responsiveness_freq is set to 400000 (400 mhz) by default. while the freq is below this value, up_threshold is the same as up_threshold_min_freq, and freq jumps to responsiveness_freq, with skipping the freq between the actual one and the responsiveness_freq. (conservative governor does not jump up to this step)

responsiveness_freq can be set to values between 100000 and 1400000

up_threshold_min_freq can be set to the same values as the normal up_threshold.

not tunable: while screen off, up_threshold is set to 95, no matter your other settings, to save more batterie.

up_threshold_min_freq is disbaled by default for conservative governor

for lulzactive:

for this governor, i did similar things, but they are not tunable till now.

when screen off:

- inc_cpu_load is set to 90, and back to the original value, when screen turns on

- up_sample_time is set to 50000, and back to the original value, when screen turns on

- down_sample_time is set to 40000, and back to the original value, when screen turns on

other changes:

- fix to touchwake from ezekeel, and another fix from stratosk

- upstream fix to compass

- building for i9000B now, too (big thanks to F4k for the hints by pn :) )

- removed some typos from recovery

- removed some annoying "no's" and "yes" from recovery in misc menu

- fixed wifi mode switch (pm_fast is the one with better signal)

14.04.2012:

- new b versions (only stock ram) changend to 377 mb, VC version needs the 720p fix from my ftp server. cmc version already patched

13.04.2012:

- updated wifi driver

- added the possibility to switch between wifi PM_Fast and PM_Max mode (Pm_Fast = better signal, PM_Max = better batterie, default is PM_Max)

- user interface to disable fsync (this gives more performace, at the risk of data loss on a crash, taken from ezekeel, so it should be ok ;) ), default is off, to be safe :)

- fixed voodoo color kernels (these have the VC in their names)

10.04.2012:

- added vibrator intensity control (by mialwe), presets can be changend in recovery

- stock ram version now available (348 mb ram), XL (390 mb), XL_bm (402 mb)

- removed 1080 mhz freq for now

- small correction to touchwake

- small correction to selective live_oc (now the low freq really are not live_oc'ed)

05.04.2012:

- fixed bug in selective live_oc, which caused the target high not taking affect to the highest freq, if highest freq equals target high

- fixed another bug in selective live_oc, which could lead to gpu crashes due to overclocking the ram, but not the cpu freq (for low steps)

- added a switch to change between "normal" and selective live_oc

by changing the live_oc mode while using it, live_oc value is set back to 100, to prevent strange things

- added possibility to set max. freq for boot (in recovery). This freq is set until init.d is executeted (it is automatically set to 1000 at this point, to make sure there are no conflicts with other cpu settings from users)

#Already in the last version, but i forgot about it:

- deep idle fixes from stratosk (many thanks)

- added possibility to underclock by using live_oc (limit is 90 now, which means lowering all freq and bus speed by 10%, to save more batterie when really needed)

03.04.2012:

For now there are three different RAM versions:

- stock mem kernel has 379 mb ram, everything working

- "slim ics" (XL) kernel comes with 390 mb, this is breaking playback of some high resolution videos

- XL_BM is coming with 402 mb ram, but breaking 720p

(while flashing the kernel, the modded rom files are also flashed, so you don't need to flash a new rom to get 379 or 390 mb)

-added new frequency: 1080 mhz (1100 does not like live_oc)

- fixed SmartassV2 for live_oc (after changing live_oc value, you have to change the smartass values, too, but then they automatically apply to the live_oc value (although you can only select 800 mhz in nstools (for example))

- touch recovery with custom devil menu (for some reason it takes a few seconds to load the first time, missing virtual keys is a warning, because there are no virtual keys yet)

-fast charge (thx to chad0989 for this), disabled by default.

while fast charge is activated you cannot connect as usb device

- added datafix script to init.d (this script is deactivated by deafult. to make it work, you have to creat a file named datafix and placed in /data/local/)

- reworking and cleaning many parts to get more ram, speed, and stability :)

05.03.2012:

- updated sio i/o scheduler to latest version

- added BLX

- upgraded BLN from V8 to V9 (working for missed calls, blinking or static light, configurabel by using NSTools or BLN Pro App)

- added Intellidemand governor

- added mdnie settings to voodoo color version

- readded deep idle v2 again (I think it is the best/only working one, although

- still using voodoo color for now, maybe two additional kernel versions tomorrow

[/quote]

Atention: kernels with i9000B in the name, are to flash only for i9000b devices!

files with .zip have to be flashed within recovery (twrp or cwm)

files with .tar can be flashed by using odin or heimdall (they are placed at the end of post 3)
