SiyahKernel v3.2.1
removed ntfs-3g from the payload part to make the kernel smaller (I want to enable LZO instead of GZIP). if you want ntfs-3g you can find it here
enabled kernel’s ntfs support to mount usb flashes in read-only mode
LZO, to have even faster booting
re-enabled j4fs and mounting of lfs partition (hellcat’s boot logo changer worked, even if it stuck with “working” popup, but it could successfully set my cat’s photo as a boot logo )
reverted 267MHz GPU voltage back to 1000mV. if you did not have a problem with v3.2, you can set it back to 950 (or even lower) with ExTweaks.
fixed vdd_levels interface. it was supposed to be using milivolts but I noticed that it was using microvolts when I tried to echoing it ‘-50′ to undervolt all steps by 50mV.

SiyahKernel v3.2.2
added support for Boot-to-Gecko (b2g) (thanks to pulser)
slightly modified panel gamma set to have smoother transition for low-level lights and this will also help a little with the battery life when the screen is on.
removed LCD panel undervolting to prevent grayish tint with low brightness
enabled SCHED_AUTOGROUP once again
added “Wipe 2ndROM data/cache” to dual-boot menu in recovery. remember that it will take long if you do not have 2ndROM data and cache files in your sdcard.
led fade-in/fade-out effects. only fade-out is available in extweaks for now as fade-in implementation is not complete.
modified panel gamma set and added a lower brightness level as the first step. if you find it too low you can set min_gamma to 1 to have stock brightness level as in GB kernel.

SiyahKernel v3.2.3
new feature: “fix permissions in 2ndROM” in dual-boot menu
new option: checkbox for “turn on the touchkey lights when the screen is touched” in ExTweaks
you will have an error when trying to flash to 2ndROM before running ‘Wipe 2ndROM data/cache’ at least once. you need to create 2ndROM data and cache files in your sdcard first.
set lulzactive default pump up/down steps depending on the frequency table step size. Default values will be initialized using the number of steps between 500MHz and 800MHz which is 3 with 18 steps.
rebased lulzactive logic on new interactive governor
new option: very simple CPU Undervolting in ExTweaks. -25, -50, -75, -100mV for all levels.
progress bar for “Wipe 2ndROM data&cache” if it is performed for the first time.
added adjustable mDNIe settings (thanks to sakura). you can use init.d script to modify the settings. the interface files are in /sys/devices/platform/samsung-pd.2/mdnie/mdnie/mdnie directory. echo 1 to user_mode and change “user_cb” and “user_cr”. default values are 128 and valid range is 0-255.

SiyahKernel v3.2.4
enabled pegasusq governor. any other existing hotplug mechanisms will be disabled if you select it.
enabled smooth scaling for pegasusq governor
set pegasusq governor as default governor using extweaks settings. ondemand will still be the default governor for recovery.
set charging touch sensitivity movfilter value the same as battery movfilter value.
default lower freq level is set to 200MHz. do not use 25 or 50 if you are going to use pegasusq or ondemand.

SiyahKernel v3.2.5
fixed some BLN problems, especially the one which causes the UI to be incredibly slow
kmemhelper binary to get/set some variables using kmem interface
added smooth level setting to ExTweaks. default is 800MHz and only effective for ondemand and pegasusq governors
removed some unused variables from pegasusq
modified pegasusq governor: made frequency_for_responsiveness (default: 100000) and up_threshold_at_min_freq (default:85) configurable and with their new default values they will not cause any rapid jumps
added hotplug governor
adjustable touchscreen thresholds. you will have to use init.d scripts until I receive some user feedback and prepare some presets for ExTweaks. check /sbin/ext/tweaks.sh for the example.
removed CPU and GPU undervolting from battery profile as it was causing crashes on some devices.
newer wifi driver
updated thunderbolt scripts and added some more tweaking which will be applied on startup.
linux 3.0.32

SiyahKernel v3.2.5.2
Patch the firmware of certain Samsung emmc parts to fix a bug in the wear leveling code
fixed wifi not working with some country codes
bcmdhd: disable ESCAN_RESULT_PATCH again
disabled smooth scaling for all governors. you can enable it back using ExTweaks.
removed wifi scan interval tweak (it is commented in /sbin/ext/tweaks.sh for those who wants it back)
updated modem_if driver
force-install superuser.apk after flashing the kernel. this will be forced each time you flash a new version and it will happen only once for each version.

Siyah v3.2.6
new usb host driver. works fine with mouse, usb sticks and serial port adapters.
some wifi patches from n7000 sources. ioctl timeout is reduced from 20 secs to 5 secs.
fixed ntfs mounting and added ntfs-3g binary back. it will not be used if “ntfs mounter” app is installed. otherwise, ntfs sticks will be mounted read-only in /mnt/ntfs folder.
changed pegasusq governor defaults using AndreiLux’s settings. see this post for details
disabled force-install of superuser but I highly recommend you to “remove root” in extweaks and restart after flashing this kernel to prevent lockups and force-closes.
added scaling_min_freq and scaling_max_freq settings to extweaks. default is 100-1200MHz, battery profile default is 100-1000MHz, performance profile default is 200-1200MHz
just a little tweak to mdnie settings… see /sbin/ext/tweaks.sh for details

SiyahKernel v3.2.6.4
new usb host driver. works fine with mouse, usb sticks and serial port adapters.
some wifi patches from n7000 sources. ioctl timeout is reduced from 20 secs to 5 secs.
fixed ntfs mounting and added ntfs-3g binary back. it will not be used if “ntfs mounter” app is installed. otherwise, ntfs sticks will be mounted read-only in /mnt/ntfs folder.
changed pegasusq governor defaults using AndreiLux’s settings. see this post for details (These settings are not used in the latest version. The settings are reverted back to older defaults while trying to fix a bug. However, it is still highly recommended to check that post and experiment with the settings)

UPDATE: 29/5 wifi&mmc related fixes.

SiyahKernel v3.2.7.1
fixed triangleaway support. boot partitions are not hidden anymore.
back to GZIP compression because of new lvm binary
nandroid backup from&restore to 2ndROM (restoring to 2ndROM will take long because of the formatting inefficiency of the data image file)
new feature: mDNIe negative effect toggling via home button. press it 4 times to toggle. I hope you will find it useful for web browsers with white background.

new wifi driver from i9300 (SGS3) sources

update(1/6): wifi driver updates from sgs3 sources.

SiyahKernel v3.2.8
lots of merges with n7000 update3 sources (/kernel /mm /fs /block /net)
and some platform specific merges (cpufreq driver and usb related)
this release is probably the last v3.2 version. in v3.3beta I will use i9300 base and have a single repository for i9100 and i9300, which requires a little more time than I have now.
XZ compression because new flags and features make the kernel to exceed 8MB with gzip compression.

SiyahKernel v3.3.1
removed lots of experimental patches and merges. why? because I got my i9300 today and my i9100 will be used by my wife and I don’t want her to complain too much.

fixed movfilter not being changed with kmemhelper (should fix touch sensitivity problems)
removed 25MHz and 50MHz CPU steps
fixed led activity on brightness change
ExTweaks settings will be reset because of GPU changes. if you revert back to a previous version make sure you reset ExTweaks settings manually.
update beta1 -> beta4: fixed gamma shift not working in ExTweaks. removed all gpu modifications to make sure we have no problems with other parts. some users (including me) experienced no problems with new gpu steps whereas some users had kernel panics when the screen is off. Consider v4.1beta4 as 4.0.2 with linux 3.0.40 and cwm-based recovery 6.0.1.1.

update beta4 -> beta5: gesture support by Tungstwenty (sample flashable zip) here is the XDA thread. some minor fixes in ExTweaks. swappiness set to 90 (effective only if you are using zram or swap). removed battery and performance profile settings during the beta phase (they will be the same as default settings)
update beta5 -> beta6: removed additional gpu steps and new frequencies

update6 -> rc1: revert back to 3.0.15 with only several cherry-picks from upstream. updated CWM-based recovery to the latest with backup type selection (dup or tar). fixed the problem of not booting after wiping data/cache. lots of refactorings and cleanups.

Reboot into 1stROM, Reboot into 2ndROM in STweaks (v5.0a2)
added back the accelerometer hack for Samsung ROMs (v5.0a2)
STweaks added to initramfs. it will be autoinstalled only once. it is my own implementation of uci.sh interface. There is almost no difference (except for resetting to defaults in the last tab) between ExTweaks and STweaks. It’s been used for some time in my S3 kernel and fairly stable. I wanted to put it in the last version of my S2 kernel as well. it is my second android app (first one is FastDormancy app).. it doesn’t have a fancy UI but not bad for a beginner (v5.0a2)
fixed voltage level rounding. it was rounding to 12.5mV steps and it is changed to 25mV. (v5.0a2)
BLNWW (BLN Without Wakelock) (v5.0a2)
Touch gestures optimizations (thanks to Tungstwenty for the latest changes and for this great feature) (v5.0a2)
added speaker and mic amplification/sensitivity settings which are based on fluxi’s mc1n2 interface, reversed and ported to uci.sh interface by dorimanx, tested and committed to my initramfs by robertobsc. (v5.0a2)
automatic led brightness level. touch voltage level will be ignored if this one is checked in STweaks (v5.0a2)

fixed a CM10 specific problem with the new GPU steps but it still doesn’t guarantee that the new steps will be stable on your device.
added slide2wake (thanks to Fluxi) + some optimizations
added mdnie interface and made hardcore’s sharpness tweaks optional in STweaks
lulzactiveq fixes by robertobsc and added cpu governor selection back to stweaks
