This is a kernel based on the pawitp's one and it works for Android 4.0.x ICS ROMs.


Features

- LiveOC
- Custom Voltage
- Voodoo Sound (implemented by pawitp)
- BLN
- 373.5MB - 398.7MB available RAM
- Compiled with Linaro 4.7.1
- O3 optimization
- Semaphore Script Manager 0.75
- Auto brightness driver
- Touch Wake
- Vibration intensity
- Deep Idle
- USB host driver
- Governor ondemand (default)
- ondemand: sampling_down_factor tunable by momentum, smooth_ui
- Governor conservative (module)
- Governor smartassV2 (module)
- Noop I/O scheduler (default)
- Deadline I/O Scheduler (module)
- Simple I/O Scheduler (module)
- Netfilter (iptables) as modules
- CIFS as module
- TUN as module
- Logcat disabled (as module only)
- Standard network packet scheduler
- Kernel log buffer size 4KB (from 128KB)
- Reduced debug info
- TinyRCU
- WiFi PM_MAX when suspend
- /system/etc/init.d directory creation if not exist

In order to load various modules of the kernel and enable or disable features use HM.Carbide's Semaphore Script Manager application. It automatically copies and runs the respective scripts from /res/scripts to /system/etc/init.d directory. The scripts:

- S05enable_oc_0800 (disable overclocking - caps max freq to 800Mhz)
- S05enable_oc_1000_default (disable overclocking)
- S05enable_oc_1100 (enable overclocking - max freq 1100MHz)
- S05enable_oc_1140 (enable overclocking - max freq 1140MHz)
- S05enable_oc_1200 (enable overclocking - max freq 1200MHz)
- S10enable_gov_conservative (load and enable conservative governor module)
- S10enable_gov_ondemand_default (enable ondemand governor)
- S10enable_gov_smartassV2 (load and enable conservative smartassV2 module)
- S15enable_sched_deadline (load and enable the deadline I/O scheduler module)
- S15enable_sched_noop_default (enable noop scheduler)
- S15enable_sched_sio (enable and load SIO scheduler module)
- S20enable_netfilter (load netfilter modules for firewall or WiFi, USB tethering)
- S30enable_logger (enable logging)
- S35enable_tun (load tun module)
- S40enable_cifs (load cifs module)

Custom Voltage may be configured with Voltage control or similar applications.

Change log

1.2.6c (11/07/2012)
- USB mass storage disable write speed cache support (thanks kasper_h, DerTeufel1980 for the hint)
- CWM: Allow key to repeat on hold (thanks to FaultException, koush). Works for volume up, down and touch key menu (as down)
- CWM: fix selection bar color when battery < 21%
- CWM: upstream sync (thanks to koush) *
- initramfs sync some changes with CM9 (adb works in root by default in recovery)
- compiled with linaro 4.7.1 201206

Normal versions (for CM9 or ROMs without hugemem configuration)
1.2.6c
- 373.5MB - 385.7MB

For Slim ROM or patched ROMs with hugemem configuration
1.2.6sc
- 386.5MB - 398.7MB

* Please note that due to changes in nandroid backup/restore, previous versions of Semaphore can't restore backups from version >= 1.2.6. To be on the safe side, please renew your backups.



1.2.5c (20/06/2012)
- rebased to 3.0.17 (thanks to trailblazerz11 and eugene373 for their github)
- compiled with Linaro 4.7.1 toolchain (thanks to trailblazerz11 for his help)
- O3 optimization flag
- upstream sync (fixes for cdma in-call volume and mic gain included, thanks to pawitp, efpophis)
- WiFi PM_MAX when suspended
- fixed 800MHz underclocking
- changed boot splash screen

- Bootloop detection (if no normal boot is detected the phone will be forced to recovery in next boot) *
- bugfix: enabling Wi-Fi hotspot twice (copy the new netfilter script in order this to work by disabling and then enabling again netfilter in Semaphore app)
- creation of /system/lib/modules if does not exist

* It doesn't mean that this will necessarily resolve the known bootloop issue, but it may help on bootloops because of bad OC/UV etc.

Normal versions (for CM9 or ROMs without hugemem configuration)
1.2.5c
- 373.5MB - 385.7MB

For Slim ROM or patched ROMs with hugemem configuration
1.2.5sc
- 386.5MB - 398.7MB


1.2.1c (20/05/2012)
- New initramfs (thanks to Mialwe for his cooperation on this)
- Bigmem reservation optional through Semaphore app (bigmem breaks 720p video recording) *
- Smooth UI implemented in conservative, smartassv2 (selected as separate option)
- Semaphore Script Manager application 0.75 (thanks to HM.Carbide)
- Fast Charge support (thanks to Chad Froebe) implemented as module **
- L4 (100MHz) int volt 1100mV (as GB)
- upstream updates
- Dropped LMK scritps

Variations:

Normal versions (for CM9 or ROMs without hugemem configuration)
1.2.1c
- 374.2MB - 386.4MB

For Slim ROM or patched ROMs with hugemem configuration
1.2.1sc
- 387.2MB - 399.4MB

* Needs reboot to takes effect. If the phone shuts down needs additional reboot.
** Enables support for fast charge. It does not enable the feature.

Great
I flashed ICS 0.9.7c on Fusion ICS Beta ....
What could go wrong? Nothing its a Semaphore Kernel !

Been using Semaphore on Mosaic and I loved it ...

Hopefully my battery life will be much better.

Thank You Semaphore ! ( creator - testers - and crew )

Just flashed this on the newly released Elite rom, everything works as expected, supersmooth.
But just as Glitch, the didle doesn't work, after activation from the app, when phone goes to sleep it never wakes up and i have to do battery pull or reset to get it on.

I have found Didle to be unreliable. I just don't enable it. There was a tutorial on how to get it to work, but you will have to search for it.

I have read in glitch thread that flashing i9000 bootloader helps and didle is working for people after changing the BL's.
I will try it in the weekend.
But sans that this kernel is running quite well.

No problem stratosk!

I think the concerns in my PM are ROM related... Maybe Grubby 0.9.0 is using an old CM build. I haven't done much research yet.

Thumbs up
Just installed and running well. I had some issues coming from Icy Glitch so I froze NS Tools via TiBu and using Semaphore App instead now. I also had some reboots when trying to OC, but setting back to 1Mhz made it smooth again.

Thank you for supporting us Captivate users

DIDLE really doesn't do anything worthy of using it. They thought it would be cool but it effects aren't that noticeable in real life. So word from the wise, don't use it....
