NTT DoCoMo SC-02C Galaxy SII version: http://dl.dropbox.com/u/4025343/siya...NTT-v1.7.8.tar

SiyahKernel v1.6reTOUCHed
all the features of v1.7 series but based on update2 sources
some stability patches

SiyahKernel v1.7.8rc2
min CPU UV value is set to 600mV.
removed bfq scheduler
increased internal voltage @1600MHz for stability

updated recovery to CWM 4.0.1.5 (la stable)
CWM flashable version wipes cache & dalvik-cache. first boot will take long time if you use CWM flashable version.

SiyahKernel v1.7.7
fixed a bug in rooting script. sorry, my mistake..

SiyahKernel v1.7.6
Better rooting script and new superuser.apk. This should solve a lot of force closes and reboots.
Moved /data/.battery-calibrated and /data/.siyah-root-installed files into /data/.siyah directory with rw permissions for everybody and the files are renamed battery-calibrated and root-installed respectively. if you remove root, you'll be able to use terminal to remove files from that directory to recalibrate battery or to reinstall root.

SiyahKernel v1.7.5
custom bootanimation, bootsound and bootlogo support. (thanks to hellcat) . my boot logo is attached (thanks to chadouming). create a folder named "import" in your sdcard and put the file in that folder. the name of the file should be logo.jpg . you can use another jpeg with the same resolution. please see hellcat's kernel thread for more info.
ondemandx governor tweaked. should be as responsive as ondemand governor when the screen is on.
just another fix for mobiletv problem with ntt version. this time it should work...
NTT DoCoMo SC-02C Galaxy SII version: http://dl.dropbox.com/u/4025343/siya...NTT-v1.7.5.tar

SiyahKernel v1.7.4
changed UV_mV_table parsing method to make UV scripts with 7 and 6 steps compatible with the kernel. if you have already UV script in init.d folder it will not cause lockups anymore.
reverted some tweaks on smartassV2 to save more battery since we have ondemandX for those who is not happy with the responsiveness of smartassV2.
initramfs additions to support 1-seg mobiletv for ntt version

SiyahKernel v1.7.3
added IPv6 privacy extensions
corrected 100MHz default voltage level (will be same as 200MHz voltage level)
added ondemandx and interactivex governors again. ondemandx seems to be stable now. default screen-off CPU freq. limit is 500MHz. interactivex may not be stable enough. use with caution.

SiyahKernel v1.7.2
fixed a nasty bug in v1.7.1
some optimizations to reduce system overhead...
install root once. remove /data/.siyah-root-installed file if you want the kernel to install it again.
reverted some optimization parameters to v1.7rc1

SiyahKernel v1.7.1
fixed charge current control interface. you can now set usb charge current.
frequency range regulation based on screen on/off events patch applied partially because it conflicts with setcpu profiles. I will try to resolve it later (credits to arighi for this great feature!)
fixed smartassv2@100MHz

SiyahKernel v1.7
Based on SGH-I777 (AT&T version) sources. new fixes and drivers...
improved automatic battery calibration script
user customizable charging speed (use at your own risk). you have to echo AC, MISC and USB charge current values to a misc device (search for it)
fixed wakeup locks with lowest clock set to 100MHz
new SIO I/O scheduler (Simple I/O Scheduler). use no-frills cpu control to change default I/O scheduler.
BFQ-v2 I/O scheduler added and set as default
fixed a bug during suspend (yes, that was not a wakelock but a suspendlock). hopefully, this will resolve all lockups.
smartassV2 tweaks...
raised lowest freq (@100MHz) to 950mV

SiyahKernel v1.6
Rebased on update2 sources (cleaned all leftovers from update1)
Compiled with 2011.03 toolchain (maybe placebo effect but I think this has increased the speed and overall responsiveness)
automatic battery calibration on a new rom installation (just leave your device connected to a charger overnight and the calibration will be done automatically every time you install a new rom). it's in initramfs. if you want to recalibrate the battery, just remove /data/.battery-calibration file and leave your device connected to the charger long enough (until the current draw becomes 0, which is a little bit longer than reaching to 100%)
increased battery polling interval to save even more battery. you know, if you observe battery level too much it decreases faster
compiled android logger as module (logger.ko). if you need it you'll load it by yourself. if you don't know what it is don't be alerted you'll be fine...
GPU undervolting (just like in JeffreySpeedfrey kernel). We'll see if it has any effect on battery life..
tweaked smartass governor to scale up slower and idle freq is set to 200.
default voltage level for 100MHz is set to 925mV.
GPU voltage interface similar to GPU clock interface (defaults are "950000 1000000" and you can echo to /sys/class/misc/gpu_voltage_control/gpu_control anything in between 800000 and 1200000 for lower and upper clock speeds respectively)
increased charging speed slightly (from 650mV to 750mV). you will not benefit very much if you keep using stock charger. I recommend you to use something which can provide at least 1A, an HTC charger maybe... I am using a Nokia charger which has 1.2A output current.
If you run this kernel without any undervolting and overclocking you will not have any lockups anymore.

SiyahKernel v1.5
auto-rooting support
auto-install of liblights with BLN support
added SLQB memory allocator and set it to default
tweaked smartassv2 governor
100Mhz clock setting with voltage value of 950mV (stock voltage for 200MHz) and smartassV2 ideal sleep frequency is set to 100MHz. If you use a script to UV, you will have to add an extra value at the end of that script to undervolt 100MHz. Setcpu users should review their settings as well.
CWM flashable version
Compiled with maximum optimizations (-O3)
Default governor is set back to ondemand (200-1200MHz). Use setcpu or no-frills cpu control from the market to use other governors or UC to 100MHz.

SiyahKernel v1.4
Android Logger enabled
removed some redundant optimization flags

SiyahKernel v1.3
BLN should be working now

SiyahKernel v1.2
reverted to CFQ I/O scheduler
more compiler optimizations

SiyahKernel v1.1 (removed. v(r)i/o was not a good choice. please use v1.0 until I post v1.2)
slightly increased charge current for CABLE_TYPE_MISC (from 450mA to 550mA). this should prevent battery drain during navigation when connected to a car charger.
NTFS support
increased readahead
V(R) I/O as default I/O scheduler
more optimizations
source code cleanups (cleanup some redundant parts), I will post the sources very soon, hopefully this weekend
smartassV2 governor as default

1400 MHz - 1200mV
1200 MHz - 1125mV
1000 MHz - 1025mV

rooting script changes summary: rooting is done once and /data/.siyah/root-installed is created. if you want to reinstall root remove that file. all su and superuser.apk files are removed (and also related dalvik-cache) then device is rebooted. if you still have problems with superuser install CWM flashable su (download from http://goo-inside.me/superuser/ ).
updated recovery to CWM 4.0.1.5 (la stable)
CWM flashable version wipes cache & dalvik-cache. first boot will take long time if you use CWM flashable version.

v2.1rc2
re-enabled auto rooting
automatic efs backup removed temporarily
auto-creation of /sdcard/clockworkmod/.salted_hash to fix problems with CWM5.X (thanks to olifee@xda)
some usb fixes (again, thanks to olifee@xda). this should fix usb keyboard & mouse problems but I could not as I am still waiting for my OTG cable.
interactive governor removed
lulzactive (thanks to tegrak) and smartass governors enabled and set lulzactive as default.
some more performance optimizations (most of them are from beta14 which seems to be the best beta in terms of performance)
added BFQ-v2-r1 io/scheduler back. some people think that it is the best for HD video recording. it doesn’t hurt to have one more i/o scheduler anyway…

SiyahKernel v2.2

FEATURES
Can be flashed on Samsung ROMs and AOSP Based ROMS. Currently all Samsung 2.3.4 & 2.3.5 based ROMS, CM7 and MIUI ROMS are supported.
Based on linux kernel 2.6.35.14 + drivers from Samsung sources
Auto-Rooting
ClockworkMod Recovery v5.0.2.7 with back button support
Boot animation support
Supports SetCPU (OC upto 1600MHz, UC downto 100MHz)
User customizable frequency steps. You cannot change the step count but you can change the frequencies at each step.
Supports undervolting (UV between 800 mV and 1500 mV)
Supports voltage control via SetCPU (thanks to netarchy, ninpo, hacre)
Stock voltages as default
smartassV2, lulzactive, lagfree governors. and lots of other governors which are available as modules
Default governor is ondemand (200-1200MHz)
Tweaked ondemand and conservative governors
Compiler optimizations
user customizable charging speed (use at your own risk). you have to echo AC, MISC and USB charge currents to a misc device.
Touchscreen fix (thanks to vitalij)
Increased touchscreen sensitivity
GPU clock and voltage control interface (thanks to netarchy).
I/O, scheduler, hotplug and vm Tweaks
automatic battery calibration. (removed. thanks to Entropy512. we do not need battery calibration for SGS2)
Available I/O schedulers: noop, deadline, CFQ, BFQ, V(R), SIO (default)
Available CPU governors: ondemand, lulzactive, smartassV2, conservative, userspace, performance, powersave, brazilianwax, savagedzen, smartass, lagfree, interactive
/system/etc/init.d startup scripts support
Automatic backup of efs partition. You will have the files in your sdcard as well as /data/.siyah directory. copy them to a safe location in case you may need them later.
Updated jhash to version 3
Increased charging speed.
BLN (thanks to creams), liblights is autoinstalled if the existing one doesn't support BLN
supports advanced touch tune driver. thanks to vitalij Link. the control app from Web, from Mobile. Thanks to tegrak for the driver patch file download
2nd core application support (thanks to tegrak)
Automounting of NTFS volumes
XZ compression for the kernel to have smaller image size. the size is still similar to previous versions after adding new features.
integrated new sha-1 and crc32 slice-by-8 algorithms
SCHED_MC enabled to have less power consumption. It will have a better support in the next version as it needs more changes in the scheduler code.
Lower brightness levels for low-light conditions to save battery.
Experimental brightness behaviour modification via setting min_bl and max_gamma values.
Native BLN support for CM7 based roms.
workqueue implementation and some other backports from linux kernel 3.1
CIFS, SLQB, NTFS and several others that I forgot...
