Got some time to play with both version i.e. 1.2.3s and 1.2.4s in last one hour (just to compare) and I think I am also favouring 1.2.3s.
Sir Stratos, already made clear what's difference between the two, theoretically 1.2.4s should have an edge but practically 1.2.3s taking the edge.

Hi,
I know this question is not really related to this thread but I didn't really know where to ask:
Does flashing stock ROM with 3 files + .pit file (re-partition) cleans remains of other kernels (like the kernel cleaning script)? If not, should I clear NStools and init.d scripts via recovery and flash this kernel again? (using 1.2.4 right now)

ODIN ROM flash with re-partition is enough.All system stuff should be trashed that way.

Yep, now it's fine Stratosk. It was the devil inside which messed up
maybe that's why it's called that way Anyway great kernel as usual, i give up with battery, on my usage i have to charge it everyday anyway and smoothness here is awesome.
P. S. Thumbs up for the tomorrow match with Russians.
I restored the old Kernel (Semaphore 1.2.2) but still have no lock screen.

Interesting observations. sUsH667 also mentioned this.
I wonder if configuration has something to do with this. I mean the governor or the scheduler is used. Maybe a governor can be optimized more that the other or something similar.
Anyway, we are still in testing phase. This is the reason I released 2 version one with O2 and the other with O3. I think, I'll try some benchmarks.
Thanks everybody for testing and feedback. I read carefully every single post and every observation and I will have them in my mind for the final version.
My tests were on all Semaphore defaults except smooth ui for both kernel versions.There is a more clear difference on games like temple run.
Sent from my GT-I9000 using Tapatalk
Strat, don't give up on O3 please! 1.2.4s has a clear edge over 1.2.3s on many aspects of everyday usage. Apps launch faster, UI is smoother and general responsiveness is greatly improved. Maybe 3 scores better at benchmarks or games, but that's not the main purpose of a smartphone. 4 is definitely better than 3.
Gonna try some heavy games, like nova3, on 1.2.4, let's see what happens
Edit: anyway, no differences in benchmarks for me, passing from 1.2.2 to 1.2.4
Edit: anyway, no differences in benchmarks for me, passing from 1.2.2 to 1.2.4
I get that impression too after upgrading from 1.2.3 to 1.2.4, with 1.2.4 I had 14% battery drain in 20h with 10h of 2g internet on, which made my mail, 2x weather apps and other internet-dependent applications (i.e. google play etc) sync periodically.
Stratosk, I think there should be two versions of this kernel: one based on 1.2.3 (better speed) and one based on 1.2.4 (better battery) but their naming must not suggest that one is newer than the other (like it suggests now).
Just my 2 cents.

1.2.4s is great! wonderful job
i wanted to ask wether it's possible with this kernel to use a script or something like "power wifi" mode on devil, wich seemed to give a nice boost to the reach of my wi fi inside my house
second this.
I 3rd this, it's a must-have feature for future releases.

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
