SiyahKernel s3-v1.9.1
based on GT-I9300_JB_Opensource_Update9
updated mali driver to support latest CM-10.1
some ramfs changes/fixes/tweaks
tested only on Samsung 4.1.2 latest official ROM and CM-10.1 nightly (30/3/2013). Samsung 4.2 leaks are not supported. Also CM10 support is dropped as I don’t want to keep 3 different mali drivers in the kernel.
v1.9.0->v1.9.1: fixed hw acceleration problems (samsung roms only). enabled zram (500MB with swappiness of 100).

SiyahKernel s3-v1.9.0
based on GT-I9300_JB_Opensource_Update9
updated mali driver to support latest CM-10.1

SiyahKernel s3-v1.8.8
1.8.7->1.8.8: fixed cm10.1 not booting when installed as 2ndROM (a tiny typo in ramfs)

SiyahKernel s3-v1.8.7
rebased on i9300 update7 sources (sudden-death issue is supposedly fixed in this source drop)
reverted temporary fix for exynos-mem exploit as i9300-update7 sources already fix that

changed “pleasant for ears” preset and set it default
boots on cm10.1 but do not use dual-boot support. it will not work yet.

SiyahKernel S3-v1.8.4
v1.8.3 -> v1.8.4: reverted VM_MAX_READAHEAD commit. adjusted cpu hotplug in/out rates in pegasusq because they were just too low after decreasing the sampling time.

SiyahKernel S3-v1.8.3
v1.8.2. -> v1.8.3: fixed problem of fb earlysuspend delay not being persisted across reboots. removed automatic installation of stweaks (you can find it on google play).

SiyahKernel S3-v1.8.2
v1.8.1 -> v1.8.2: fixed gpu voltage problems

SiyahKernel S3-v1.8.1
Ported CPU UV tab from AndreiLux’s STweaks config
Dynamic generation of STweaks config and initial GPU voltages are set correctly (mostly based on AndreiLux’s uci.sh script interface while trying to keep the changes minimum to support other guys using my scripts as base)
Workaround for CRT animation problem (at the bottom of the screen tab in STweaks)
fixed the problem of copying large files that some users experience
removed custom modifications from pegasusq governor and changed the tweaked values a little

SiyahKernel S3-v1.8
rebased on Samsung’s N8020 sources (mainly some CMA_DMA changes/fixes/optimizations, driver & platform code changes and some additional pegasusq logic)
fine tuning on pegasusq governor
some tiny ramfs changes such as adding governor selection back to STweaks

“Black Crush Fix” by AndreiLux.
car dock support.
Added this to ramfs (thanks to Oranav@XDA) to fix EasyUMS compatiblity in cm10.
new STweaks (500% faster startup, retouched UI ) which is also available on Google Play
applied wifi changes in CM10 repo to fix wifi tethering problem.
Based on update6 sources.
added discrete wakelock stats and gestures (both by Tungstwenty) back.
dns_resolver and md4 modules are linked into the kernel, so loading cifs will be enough to use smb shares.
single image for kernel and recovery, if you flash it to boot partition it is a kernel, if you flash it to recovery it is a CWM-based custom recovery (hijack-recovery is available in STweaks to flash the kernel as a custom recovery).
added cm10′s wireless driver as a separate module.
increased mmc timeout even more. added default ROM selection in STweaks.
disabled gpu resume freq and gpu boost completely.
tweaked pegasusq a little more. ramfs updates for samsung and cm10.
ported slide2wake from fluxi’s implementation (WIP. still need some more work).
back to new MTP driver.

SiyahKernel S3-v1.7rc3
Jetzt muss auch der Recovery Flash nicht mehr Extra installiert werden..

v1.7rc2 -> v1.7rc3: reverted cyanogenmod mdnie scenario commit. reverted wireless driver and added cm10′s wireless driver as a separate module.

v1.7rc1 -> v1.7rc2: new STweaks (500% faster startup, retouched UI ), applied wifi changes in CM10 repo to fix wifi tethering problem. Based on update6 sources. added discrete wakelock stats and gestures (both by Tungstwenty) back. dns_resolver and md4 modules are linked into the kernel, so loading cifs will be enough to use smb shares. single image for kernel and recovery, if you flash it to boot partition it is a kernel, if you flash it to recovery it is a CWM-based custom recovery (hijack-recovery will be available in STweaks to flash a custom recovery).

SiyahKernel S3-v1.7beta6
Jetzt muss auch der Recovery Flash nicht mehr Extra installiert werden..
added backup/restore to 2ndROM utils. Make sure you backup your 2ndROM before you flash v1.7rc1 because there will be some radical changes in dual booting and you will have to restore your 2ndROM backup after flashing it.

SiyahKernel S3-v1.7beta5
Jetzt muss auch der Recovery Flash nicht mehr Extra installiert werden..
added (again) gpu boost on touch. set touch boos default back to 800MHz. updated bcmdhd driver to the one in korean s3 driver. mali refactorings (new_* interfaces removed from /sys/module/mali/parameters. this will fix malistatus problem).

SiyahKernel S3-v1.7beta4
Jetzt muss auch der Recovery Flash nicht mehr Extra installiert werden..
replace the recovery image with the new one which was forgotten in the previous release. fix permissions on 2ndROM should be working now. Made a change in wifi offload filtering to deny muticast packets but allow multicast DNS packets.

SiyahKernel S3-v1.7beta3
Jetzt muss auch der Recovery Flash nicht mehr Extra installiert werden..
Recovery is merged with the kernel, no more separate recovery. Flash back your favorite recovery and use STweaks to boot into 2ndROM-utils (which is another CWM-based recovery built into the kernel). Added “no boot logo” option to STweaks. Added “Reboot into 2ndROM Utils”, “Reboot into First ROM” and “Reboot into Second ROM” options. Added “Fix 2ndROM permissions” and “Wipe 2ndROM cache” (wipes only cache partition, not data) to 2ndROM-utils. Fixed some bugs in 2ndROM-utils. Added “Black Crush Fix” by AndreiLux. lcd freq is decreased just a bit to save a little power.

SiyahKernel S3-v1.7beta2
Jetzt muss auch der Recovery Flash nicht mehr Extra installiert werden..
v1.7b1 -> v1.7b2: new recovery features: installing zips to secondrom, wipe 2ndROM data/cache & dalvik, fix 2ndROM permissions, exfat support. Fixed system partition cannot be mounted read/write. The recovery will be flashed together with the kernel.

SiyahKernel S3-v1.7beta1
Vor diesem Kernel, sollte der neue Recovery-i9300-Siyah geflasht werden...

• Dual-booting (supports only JB ROMs: Samsung JB and CM10)
  
• fixed a UMP related bug in v1.6.8 that was causing lags for CM10 users
  
• removed CPU locking when GPU freq >=440MHz
  
• alternate touch recovery for secondrom related operations
  
• Some 2ndROM features are missing. Implemented features are: Clone 1stROM
  to 2ndROM, Clone 2ndROM to 1stROM, Swap ROMs, Delete 2ndROM.
  

TODO:

• implement missing 2ndROM features
  
• make a CWM-flashable 2ndROM-utils app
  
• implement more accurate space requirement checks
  

Some recovery details:

• CWM-based Recovery v6.0.1.4
  
• default backup format is set to tar (you can set it to dedupe)
  
• In kernel recovery options: delete stweaks defaults or remove init.d
  scripts
  
• In dual booting menu: swapping, cloning and other 2ndROM related
  options
  
• swipe gestures support (up/down to choose menu items and right/left
  to select/back)
  
• doubletap to select (needs a little more tuning though)
  
• uses Samsung JB stock kernel recovery as the base
  

Some details about dual-booting:

• 2ndROM system partition will be kept in /sdcard/.secondrom/system.img.
  You will need 1.5GB space for the 2ndROM system partition in your
  internal sdcard.
  
• both data partitions in 1stROM and 2ndROM will use the same space.
  Make sure you have enough space to hold both system and data when you
  clone 1stROM to 2ndROM.
  
• hidden partition is used as 2ndROM cache partition.
  
• Flashing a new ROM may flash another kernel and you will not be
  able to boot into 2ndROM anymore. But you will not lose it unless you
  delete “.secondrom” folder in your internal sdcard. So, flashing back
  SiyahKernel will let you boot into 2ndROM again.
  
• See this post for more details. It is for S2 but still useful to
  understand what dualbooting is about.
  

SiyahKernel S3-v1.6.8
v1.6.7->v1.6.8: fixed mdnie sharpness tweaks causing strange artifacts on boot animation. removed process priority tweaks. removed some unnecessary patches. Enabled GENTLE_FAIR_SLEEPERS in default profile (either enable yourself if you are an existing user or reset stweaks if you want it to be enabled). You will see siyahkernel logo as I made this release while working on dual booting and did not spend any time to remove those, create “.nobootlogo” file in your internal sdcard if you find it too disturbing. Fixed setcpu showing 1704 when overclocked to 1700.

SiyahKernel S3-v1.6.7
v1.6.6i -> v1.6.7: removed last remaining module and linked it into the kernel (mdnie_mods). Made all mdnie variables configurable via misc device (all in /sys/class/misc/mdnie). Hardcore’s sharpness tweaks are converted into a script to use the new interface as an example.

SiyahKernel S3-v1.6.6i
v1.6.5 -> v1.6.6: changed TMU thresholds a little. fixed freq scaling stuck at some frequencies. removed cfs tweaks from stweaks. some experimental process priority modifications to have better UI experience. most of the custom modules are now linked into the kernel and not loaded as modules. lulzactiveq tweaks.

v1.6.6 -> v1.6.6i: one line fix for freq being stuck at 1704MHz. changed process thresholds a little.

SiyahKernel S3-v1.6.5
v1.6.3 -> v1.6.4: new CPU steps (1700MHz & 1800MHz) (thanks to AndreiLux as I used his kernel and multipliers while making the changes). fixed mali module related problems. fixed lockup problem while charging the device when it is off. reverted most of the changes back to v1.5 state which were removed during the lag-hunting process (discrete wakelocks, gestures, voltages…etc).

v1.6.4 -> v1.6.5 re-adjusted regulator constraints which were lost because of the removed module. fixed touch boost setting. enabled swap.

SiyahKernel S3-v1.6.3
v1.6.2 -> v1.6.3: change packet filter settings to block multicast (thanks to Entropy512). fixed mali UMP mistakes which might be causing problems on Samsung ROMs. Reverted mali cpu lock levels to stock.

SiyahKernel S3-v1.6.2
v1.6.1 -> v1.6.2: cleaned ICS leftovers from ramfs. adjusted maximum GPU voltage constraint (1075mV->1400mV). increased default GPU voltages by 25mV. This version will reset all your STweaks settings to defaults. Enabled swap (still no zram).

SiyahKernel S3-v1.6.1
v1.6 -> v1.6.1: reverted mtp driver to fix mtp problems on osx. removed some tweaks which were suspected to degrade performance. reniced kswapd0 to have lower priority. new wifi driver from n7105 sources.

SiyahKernel S3-v1.6RC3
mali as module (this version supports both Samsung JB and CM10 ROMs). removed swap & zram. fixed gpu clock setting problem. removed gpu boost temporarily. updated UMP driver. Added arm topology support again with cpupower driver. better loadavg calculation (thanks to AndreiLux for his merges from upstream) (v1.6rc3).

SiyahKernel S3-v1.6RC2
5-step GPU, new frequency steps for GPU, gpu boost on touch and some other GPU related modifications/cleanup. removed zram settings from samsung’s init.rc and added it back to stweaks. (v1.6rc2)
