First of all thank you for your hard work!Also I have a noobish question, I'd like to try overclocking above 1200 is there any way I can do this with the semaphore app? Thanks!
Although, I don't recommend it, because LiveOC overclock bus speed also you may try this to OC up to 1300MHz:
Copy the script S05enable_oc_1200 to /sdcard/SemaphoreScripts/S05enable_oc_1250 (if you want to OC to 1250MHz). Edit the script you copied and change 120 to 125, the description 1200 to 1250 and the echo 1200000 to 1250000.
The script should be available in Semaphore script manager application.
Can you please clarify? I feel I missed something..
Thanks, my friend. I don't have my name on any records but I can ensure you hearing a negative review after a year (tomorrow Semaphore has it's birthday) of really hard work, simply hearts.
Who's touching my good friend?
Forget about bad talks who cares about them.
I have one problem.I cannot make new kernel to crash.
I tried everything.Clear cache,dalvik cache,install another rom without wipe i tried every possible situation.It works great.
I must say all my problems with lost recovery are gone.Now i really enjoy my phone.
Fantastic kernel.
Many regards
My good friend!
Of course you can crash it. But thank you so much for everything!
I'm glad that I hear that bootloop detection worked!
Smooth ui is a separate option in 1.2.2 and affects every governor.
On CM9 with latest Semaphore installed, every time my phone is idle and I receive a call, phone will FC the phone app and I won't be able to answer the call. Anyone else experiencing this?

Only one year ?!
I feel like I've been enjoying your work for much longer than this.
Guess it's been a real roller coaster year for you considering everything but remember this when you feel bad : there are not that many people on earth that made so many others from all around the globe appreciate their work/creation as much as you did with Project Semaphore.
I'm not only talking about kernel dev for Android. It applies to any aspect of life.
You are part of the 1% of the people who do make a difference somehow, somewhere.
P.S.: Mea Culpa here ... I'm not running Semaphore at the moment as I'm in the process of making sure Slim 3.9 is stable. That shouldn't last more than a few more days though...

I really don't have words to say my friend... Many many thanks. I will remember your post.
If I didn't have support from you and from other people here, Semaphore project would be closed long time ago.
THANK YOU
Thanks! I figured it out. Which governor is best with it in your opinion? Using Ondemand 40 now.
And yeah, the bootloop detection worked. I thought I'd have to pull the battery but it came out of it and went to recovery.
Then I ran cleaning script again an reflashed. Working now.
No, thank *you*
I've switched my S for a Note, now, and although it's very nice, I do very much miss Semaphore.
Fortunately, I look after my wife's S, too, so I'm still here
thanks again for all you've done, and do. you are very much appreciated.
Can you please clarify? I feel I missed something..
Oh just remember the paritions back in GB, we had either EXT4 or RFS? I can't remember what ICS is using lol. I never saw it brought up or mentioned either...
Do you also have problem with other apps?
Maybe you can try to clear data of phone.apk app or try a dalvik and cache clearing.
/system, /cache, /datadata use yaffs2 (Yet Another Flash File System version 2). /data use ext4
It's the file systems that google use on Android.

Please version with VOODOO COLOR
I'm really sorry, but not in my plans. Maybe in the future.
Thanks for feedback.
Semaphore app is a script manager app (that's why the name). I can only place scripts in /Res/scripts directory and app can parse them, present them and copy or remove them from init.d directory.
So, I could make a script to reset didle stats but I could not make anything to present stats.
You could make also your script because HM.carbide made this app capable to handle user's scripts.
Copy the file /res/scripts/ S24enable_didle_stats to /sdcard/SemaphoreScripts/tests with a different name and edit it. It's very simple. Just replace the only working line in the script to :
echo 1 > /sys/devices/virtual/misc/deepidle/reset_stats
Also change the second and third line with your own description.
Save it and open Semaphore app. In miscellaneous section you should see your script.
Please version with VOODOO COLOR
I don't know why you want that when you can pretty much tweak the colors using color tuning in Galaxy S settings app.
I'm perfectly happy with my settings, nice colors and contrast and no greenish flicker. These are my settings:

I find that many people have their own personal tweaks for "Voodoo Color." However I can't really tell the difference between the real Voodoo Color and tweaks made by Galaxy S Settings, or left at default. They all look generally the same to me... Maybe if I had two phones to compare it then it'll mean something lol.
Btw I have 20/20 vision. Maybe I'm just not picky?

I'm pretty sure they are the wrong way round. I run a script to remove unwanted sounds and place my ringtones in the system after I flash. To move files that are stored in /emmc/ when the phone is running, I have to use /sdcard/ in the script for CWM.

It's a little tricky to tell. I can see the difference, but I wish there was a way to quickly switch between them so I could see which I preferred. Oh well, I suppose.
I'll run with beint's for awhile. Looks good at a glance.
As Semaphore support Fast Charge function but will not enable it, if I already have the script in the init.d folder, how can I make sure Fast Charge is actually enabled on my device? If I don't want to depend on feeling it.

1.2.5e Euro 2012 - Spain Special Edition100Deep Idle Guide and FAQ
This was really unexpected. Unfortunately I can't answer all these questions and comments. So I tried to write a guide and a FAQ for deep idle. Feel free for suggestions and corrections. Source: Samsung's SPV210 RISC Microprocessor User's Manual. Hope it clarifies some things.
Deep Idle Guide and FAQ
When the phone has no actions to perform, because you leave it alone or for example contacts are not synchronizing or gmail application is not fetching a new mail e.t.c., then the best thing that the phone has to do is to go to... sleep (suspend). In this state the phone consumes very little power.
There are also 5 other power schemes that the processor s5pv210 can use to reduce power consumption: Normal, Idle, Deep Idle, Stop and Deep Stop. We are interested in the first three states Normal, Idle and Deep Idle.
In Normal state the CPU is running, that is, some software is running.
In Idle state the CPU core is idle, that is, the CPU core clock is disabled but the remaining parts of s5pv210 are running.
In Deep Idle state the CPU core power is supplied but is powered off by the internal power switch. The remaining parts of processor may become power gated except the Audio power domain for low power MP3 playback.
Samsung in gingerbread kernels used only the Idle scheme. Deep Idle was implemented in the kernel but it was disabled by default. All known GB custom kernels have enabled Deep Idle state.
With stock kernels only Normal, Idle and Sleep states are used. Examples of these states use:
Normal state: User uses browser, or reading emails, watching video etc
Idle state: User listen to music and screen is off, no other software is running.
Sleep state: No user activity, screen is off, no activity of background services and processes.
Kernel checks many times per second different factors and decides which power state to use.
Deep Idle can be used as a better alternative of Idle state and the major benefit is when user listen to music. Then IF and only if all other conditions (factors) are satisfied the kernel decides to go to Deep Idle. That is, as we mentioned, CPU powered off, TOP powered off and L2 cache is powered off. Only Audio is on and that's why we have a major benefit. Another option of Deep Idle is the TOP=ON which means that the TOP module is still powered. This is used when bluetooth is enabled (powered).
Regarding power consumption, Sleep is always the desired state. Below the states ordered by the power they consumes (Normal consumes more power):
Normal -> Idle -> Deep Idle (TOP=ON) -> Deep Idle (TOP=OFF) -> Sleep
FAQ
How to enable Deep Idle?
a) Simply check the Deep Idle option in Semaphore Script Manager or b) use this command on a terminal emulator or adb shell:
echo 1 > /sys/devices/virtual/misc/deepidle/enabled
How to enable Deep Idle Statistics?
a) Simply check the Deep Idle Statistics option in Semaphore Script Manager or b) use this command on a terminal emulator or adb shell:
echo 1 > /sys/devices/virtual/misc/deepidle/stats_enabled
Why statistics are not enabled by default?
Simply for saving CPU cycles. Kernel checks for entering Deep Idle (or Idle) many thousand times per minute. So, disabling statistics we have less overhead in CPU. What is the difference? Not to much, but better little than nothing.
What is TOP?
S5PV210 internal modules are grouped into 11 power domains based on their functions. One of these domain is the TOP and it includes these modules: Clock Management Unit (CMU), GPIO(OFF), Bus components, VIC, TZIC, Internal memory (IROM and IRAM), NAND controller, OneNAND controller, CF controller, SRAM controller, Peripheral DMA, Memory DMA, CoreSight, JTAG, Modem interface, Security sub-system, TSI, HSMMC, USB HOST, USB OTG, DRAM controller, CHIPID, IEM_IEC, Security key, SPDIF, PCM, SPI, KEYIF, TSADC, I2C, I2S channel 1 and 2, AC97, PCM, System timer, Watchdog timer, UART.
So, Deep Idle with TOP=OFF power gates all the above modules.
How to check if Deep Idle works?
Enable Deep Idle and Deep Idle statistics then run music player and select your favorite music (it must be your favorite song in order to deep idle work properly). Switch the screen off and wait few seconds (or wait until your favorite song is finished). Check with this command in a terminal emulator or adb shell deep idle statistics:
cat /sys/devices/virtual/misc/deepidle/idle_stats
Alternatively you may just open the idle_stats file in the above directory using a root explorer like application.
I only get TOP=ON statistics
Bluetooth or GPS or Vibrator is running
How to power down Bluetooth?
Use this command:
echo 1 > /sys/devices/platform/bt_rfkill/rfkill/rfkill0/soft
Unfortunately I didn't manage to find a way to enable it again. I tried an rfkil script but it doesn't work for me. If you find a way, please let me know.
I only get Idle statistics (neither TOP=ON nor TOP=OFF)
Something is preventing kernel to enter in deep idle state. This maybe normal. For example:
LCD controller is enabled
USB is connected
TV encoder is working
G3D (GPU) is active
MFC (multi format codec) is active
SDMMC controller is active
etc.
How can I find what is preventing deep idle?
That's why I implemented dflags in deep idle. Kernel check many factors to decide if it can enter deep idle. All these check are encoded in dflags. dflags is an integer number. If you read this number and decode it in binary you will get the results of the last check. Each check is a bit set in binary format. For example:
dflag = 3 binary = 11. This means that LCD controller and camera are active. (Please note that I disabled camera check for preventing kernel entering deep idle). The flags in dflags (most of the are self explanatory):
0 S5PV210_PD_LCD
1 S5PV210_PD_CAM
2 S5PV210_PD_TV
3 S5PV210_PD_MFC
4 S5PV210_PD_G3D
5 SND_S5P_RP
6 S5P_CLKGATE_IP0
7 S5P_CLKGATE_IP1
8 S5P_CLKGATE_IP3
9 loop_sdmmc_check
10 check_usbotg_op
11 check_rtcint
12 check_idmapos
You may enable debugging with
echo 1 > /sys/devices/virtual/misc/deepidle/ddebug_enabled
The you may use this script to get the value of dflags every second.
Code:#!/system/xbin/busybox sh while true; do cat /sys/devices/virtual/misc/deepidle/dflags sleep 1 done
Leave it to run and try to enter your phone in deep idle. The switch on the screen and read the last values and convert the to binary. Values 0 or 1 lead to deep idle. Other values lead to Idle.92How to build Semaphore kernel
Prerequisites
Basic knowledge of Linux is required to be able to build the kernel. We will also need a modern Linux box (preferably).
Basic Setup
First, we need to setup a directory in which we will clone the kernel and initramfs repositories. In this guide, we will setup them in /tmp but you can do it in any directory you want.
In a terminal we run:
Code:mkdir /tmp/semaphore cd /tmp/semaphore
Then we clone the basic kernel repository:
Code:git clone https://github.com/stratosk/samsung-kernel-aries
Finally we clone the initramfs repository:
Code:git clone https://github.com/stratosk/ics-ramdisk
OK, first step done. We got the code. Now we have to do some preparation and compile it.
Configuration
I prefer to use a mini ugly script to compile the kernel and pack it. It's located in the root of the kernel tree (/tmp/semaphore/samsung-kernel-aries/sbuild.sh)
We open this file with an editor of our choice (I prefer vi) and edit:
1) The two lines with the 'make' command, changing the CROSS_COMPILE= option. We need to set the path from the cross compiler toolchain. I use the one that it's included in CM9 repository.
2) The line starting with the 'find' command, changing the kernel source directory and destination directory of the modules location. This is into the initramfs directory. In our example it's /tmp/semaphore/ics-ramdisk/ics_combo/files/modules
The Semaphore's kernel configuration is located in the file config_sema in the root kernel directory. So, we need to copy this file as .config:
Code:cp config_sema .config
Then we run this command to start the Linux kernel configuration utility (again change the CROSS_COMPILE according to your toolchain directory):
Code:make CROSS_COMPILE=/kernels/semaphore_cap/android/android/system/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin/arm-eabi- ARCH=arm menuconfig
We go to 'General Setup' section and we change the 'Initramfs source files' option to /tmp/semaphore/ics-ramdisk/ics_combo/
We also need to change the next 2 options User ID and Group ID to whatever uid and gid we are logged in in the Linux box. In my case is 500,500. We exit and save the configuration.
Compiling
Now we are ready to build the kernel!
We just run:
Code:./sbuild.sh
We wait few minutes (time depends on the machine) and hopefully the compilation will end.
The script will produce 2 files.
1) /tmp/semaphore/samsung-kernel-aries/arch/arm/boot/zImage
2) /tmp/semaphore/ics-ramdisk/cwm/Semaphore_ICS_1.2.0s.zip
These are the 2 known files that we can flash via Heimdal or CWM respectively.68Please accept my apologies
@all
Please accept my apologies about this comment.
I guess I was very tired trying to prepare the new version, and hearing about these problems and almost no comments about the new stuff make me decide to stop this project.
But, during the day and after reading all these beatiful comments from all of you, I realized that Semaphore is part of my life. It sounds a little bit exceeding saying this but it's true.
For almost a year this project and most of all the communication with all of you is an important part of my life.
And it would be unfair for all of you and for me to kill Semaphore.
@Znida
I'm sorry. My commect was general and I didn't mean to blame you for anything.
@mialwe
Thanks about your comment my friend. It's good to hear that from a person like you.
@bennybaz
Thanks so much trying to help. Beers it's not the issue. As I said I work on Semaphore for year and the $600 is not the reason I still working for this.
Of course it's a huge help for me and many thanks to everybody who donate to me.
@greasyguy
Thanks mate, really appreciated.
@all
Thanks again for your nice comments. You gave me the motivation to start working again. THANK YOU!
