Make sure to disable this option before convert to ext4. You may enable this after the conversion
In order to control voodoo sound and color and BLN you have to download Voodoo Control and BLN control applications respectively from android market.
The max CPU frequency is by default 1Ghz.
You may use applications like Voltage Control to control UV.
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_1000_default (disable overclocking)
- S05enable_oc_1200 (enable overclocking to 1200MHz)
- S05enable_oc_1300 (enable overclocking to 1300MHz)

Alternative download from www.semaphore.gr/downloads/captivate

Ok here's a CWM flashable zip of semaphore I have update the script to delete the new voltage settings of darek.xan and the oc script of semaphore to make it more stable on first boot.
NOTE:
THIS WILL REMOVE YOUR VOLTAGE SETTINGS AND OC SETTINGS, YOUR FIRST BOOT WILL TAKE LONGER DUE TO THE DALVIK CACHE IS WIPE OFF GIVE A LITTLE MORE TIME TO BOOT

try it now, thanks stratosk!
PS: where I can download bigmem version?

It'll be out in due time when he knows everything works on the Captivate.
With the test version he posted in the I9000 thread, everything but capacitive search button worked. And since my phone isn't 100% stable, more testing is required.

Convert to ext4/RFS by using the chainfire ext4 app

first bug:
Script to change /cache to virtual 50MB (in case you want to download apps > 30MB from Market)
-> when enable it, market can't download or update app ^^!

Have you tried restarting the phone? I remember reading about that. I think you need to do this on ext4 partition, and restart the phone.
I'm happy to report that Semaphore feels like a good release, and that it's not beta anymore.

@geokilla
Thank you for testing the first Captivate version and for encourage me to release this version. I patched this version with all the changes that existz (many many thanks) suggested. 1.8.2 version is very well tested for i9000, but I still call captivate version 'beta' since I don't have a captivate to test it.
@saobang3886
Additional installed busybox versions may cause this error. Kernel comes with an embedded busybox version. Please try to uninstall any busybox version you installed and retry.

I will check the code and if it is possible to use it, I will do it.

Update. Phone.apk and Messaging.apk closed on me only a couple times during the 36 hour of up time I had.
Anyone else getting this "problem"?

Since this is a remake of i9000 kernel, does this have the charging bug ? I mean, when I charge my phone (JVS/JVT kernel):
1. It never reaches 100%.
2. If I leave it on charger after the "phone charged" notification it loses charge quite a bit !
If someone can answer, will be helpful to decide whether to flash.
Thanks.

Kernels with VC in the name are coming with Voodoo Color

Changelog:
changelog 02.08.2012:
- bug fix to bln, to prevent kernel panic in some situations (thx to thalamus)
- switched from deep_idle 2 to idle2 (also thx to thalamus)
- updated kernel to linux 3.0.38
- dockaudio sysfs for captivate and fascinate
IDLE2 can be enabled with the following command:

IDLE2 can be disabled with the following command:
echo 1 > /sys/module/cpuidle/parameters/idle2_disabled
Stats can be obtained from the standard cpuidle interface, which, for
IDLE2 is located at:
/sys/devices/system/cpu/cpu0/cpuidle/state*/time
where * = 1, 2, 3

changelog 27.07.2012:
- hack mfc driver, to give all available mem to an application, if the requested mem is more than the max. available (maybe useful later, does not change anything right now (afaik))
- fix execution of boot-patch.sh, disabled twice execution of init.d, enabled tv-out server for all devices (i9000 already had this)
- battery: fix charging display for car dock
- increase read-ahead on moviNAND
changelog 25.07.2012 part2:
- fixed cwm backup and restore for kernels without /datadata partition
changelog 25.07.2012:
- updated recovery (no "sdcard format"-bug anymore, external sd card is named correctly)
- vibrant: hopefully fixed froyo ril
- jellybean: galaxy s settings working now
changelog 22.07.2012:
- updated kernal base to linux 3.0.36
- updated "block" to linux 3.3
- readded fiops io scheduler (kept cfq this time)
- updated cwm recovery to 6.0.1.0 (please create a new nandroid, because of possible incompatibilities between old/new recovery)
- compiled with linaro toolchain (gcc 4.7.1) and O3 compiler flags
- made uksm scan less often (save cpu time and power)
- at first boot: only delte init.d scripts created by other kernels
- increased usb write performance
- lowered ram and display voltages a little bit
- fixed some bugs related to devil settings (they should stick now after reboot, if set by one of the devil apps)
- support for scripts in /system/etc/shutdown.d (thx to Efpophis)
all scripts placed at /data/local/shutdown.d or /system/etc/shutdown.d get executed at shutdown/reboot
you can use this, to play a shutdown sound for example.
by default 00shutdown gets created, which plays a music file, when it is placed at one of these folders/places
/system/media/audio/ui/shutdown.ogg
/data/media/audio/ui/shutdown.ogg
Click to expand...
Click to collapse
- disabled some debugging options
- audio (and for fascinate: camera fixes) by Efpophis+
- patch for improving batterie life by CML
- nfts read/write driver built in (for use with usb host mode)
- reverted refreshrate_mod and gpu_oc mod, as both weren't working
changelog 18.06.2012:
- some changes to load balancing
- added ultra ksm (metioned by zach thx for this my friend)
- readded fiops io scheduler (still experimental and could cause instablilities)
- using snappy compression for zram now (2 times faster, but only 2% less compression)
- added the possibility to change zram size (at /data/local/devil/zram_size, with valid values: 50, 75, 100 and 150 (all in mb))
- fixed the applying of user_min/max freq after reboot
- vibrant: fixed gps
- fascinate: fixed nandroid in cwm recovery
what is ksm? http://en.wikipedia.org/wiki/Kernel_SamePage_Merging_(KSM)
uksm is more optimized and also working for single core systems. using this should give much better ram usage, but at the cost of more cpu usage
############# most probably not working (yet)##############
i have added seperate gpu oc from jt1134's galaxy_tab (to switch between 200 and 250 mhz), but i did not get any improvements in antutu...further tests needed
echo 1 > /sys/kernel/pvr_oc/pvr_oc (for 250 mhz)
echo 0 > /sys/kernel/pvr_oc/pvr_oc (for 200 mhz), no reboot needed
and also have changend default screen refreshrate from 60 to 56, with the possibility to change it:
echo 1 > /sys/kernel/refreshrate/enable (60 hz)
echo 0 > /sys/kernel/refreshrate/enable (56 hz)

changelog 01.05.2012:
- all changes from cm9 stock kernel (including mount points option)
- some fine tuning to deadline and sio
- Devil Idle: limiting bus/ram/gpu speed to 100 mhz for 100-800 mhz cpu freq, while screen off (automatic mode) or always (permanet), both modes automatically reduce the int voltages of the affected freq by 50 mV
- compiled with swap support
- added stratosk's smooth_ui to lulzactive governor (activated by default)
- rest oc_value to 100 while screen off, and back when screen turns on (combined with devil idle automatic, can't be turn on/off without devil idle)
- added posibility for different voltages while screen off (also bundled with devil_idle, with default settings, stock arm voltages are applied, because of live_oc set to 100)
- added the possibility to set freq limits while screen off (min and max freq)
19.04.2012
- even better fix to selective live_oc (last one (in test kernel) generated some overhead)
- fixed sampling rate of ondemand and conservative (have ported mialwe's/stratosk's sleep multipliers)
- new tunables for ondemand and conservativ
sleep multiplier and tunables:
mialwe and stratosk had the great idea, to change the sampling rate of conservative and ondemand governor while display of. for this, he introduced the sleepmultiplier (in his case factor 3). this means, if you set sampling rate to 20000, it changes to 60000 while screen off, and back, when screen on.
for ondemand and conservative:
i have made this multipliers tunable. proper values are between 1 and 5, because one could want a higher multiplier while screen off, if sampling rate is very low while screen on (higher sampling rate means, less checking for work load --> better batterie, worse performance). with this tunables you get better batterie, without making the performance worse while screen on.
two other tunables: up_threshold_min_freq and responsiveness_freq
the first one is a very low threshold while on low freq (by default 40), to make the governor scale up faster, until the responsiveness_freq is reached.
the responsiveness_freq is set to 400000 (400 mhz) by default. while the freq is below this value, up_threshold is the same as up_threshold_min_freq, and freq jumps to responsiveness_freq, with skipping the freq between the actual one and the responsiveness_freq. (conservative governor does not jump up to this step)
responsiveness_freq can be set to values between 100000 and 1400000
up_threshold_min_freq can be set to the same values as the normal up_threshold.
not tunable: while screen off, up_threshold is set to 95, no matter your other settings, to save more batterie.
up_threshold_min_freq is disbaled by default for conservative governor
for lulzactive:
for this governor, i did similar things, but they are not tunable till now.
when screen off:
- inc_cpu_load is set to 90, and back to the original value, when screen turns on
- up_sample_time is set to 50000, and back to the original value, when screen turns on
- down_sample_time is set to 40000, and back to the original value, when screen turns on
other changes:
- fix to touchwake from ezekeel, and another fix from stratosk
- upstream fix to compass
- building for i9000B now, too (big thanks to F4k for the hints by pn )
- removed some typos from recovery
- removed some annoying "no's" and "yes" from recovery in misc menu
- fixed wifi mode switch (pm_fast is the one with better signal)
14.04.2012:
- new b versions (only stock ram) changend to 377 mb, VC version needs the 720p fix from my ftp server. cmc version already patched
13.04.2012:
- updated wifi driver
- added the possibility to switch between wifi PM_Fast and PM_Max mode (Pm_Fast = better signal, PM_Max = better batterie, default is PM_Max)
- user interface to disable fsync (this gives more performace, at the risk of data loss on a crash, taken from ezekeel, so it should be ok ), default is off, to be safe
- fixed voodoo color kernels (these have the VC in their names)
10.04.2012:
- added vibrator intensity control (by mialwe), presets can be changend in recovery
- stock ram version now available (348 mb ram), XL (390 mb), XL_bm (402 mb)
- removed 1080 mhz freq for now
- small correction to touchwake
- small correction to selective live_oc (now the low freq really are not live_oc'ed)
05.04.2012:
- fixed bug in selective live_oc, which caused the target high not taking affect to the highest freq, if highest freq equals target high
- fixed another bug in selective live_oc, which could lead to gpu crashes due to overclocking the ram, but not the cpu freq (for low steps)
- added a switch to change between "normal" and selective live_oc
by changing the live_oc mode while using it, live_oc value is set back to 100, to prevent strange things
- added possibility to set max. freq for boot (in recovery). This freq is set until init.d is executeted (it is automatically set to 1000 at this point, to make sure there are no conflicts with other cpu settings from users)
#Already in the last version, but i forgot about it:
- deep idle fixes from stratosk (many thanks)
- added possibility to underclock by using live_oc (limit is 90 now, which means lowering all freq and bus speed by 10%, to save more batterie when really needed)
03.04.2012:
For now there are three different RAM versions:
- stock mem kernel has 379 mb ram, everything working
- "slim ics" (XL) kernel comes with 390 mb, this is breaking playback of some high resolution videos
- XL_BM is coming with 402 mb ram, but breaking 720p
(while flashing the kernel, the modded rom files are also flashed, so you don't need to flash a new rom to get 379 or 390 mb)
-added new frequency: 1080 mhz (1100 does not like live_oc)
- fixed SmartassV2 for live_oc (after changing live_oc value, you have to change the smartass values, too, but then they automatically apply to the live_oc value (although you can only select 800 mhz in nstools (for example))
- touch recovery with custom devil menu (for some reason it takes a few seconds to load the first time, missing virtual keys is a warning, because there are no virtual keys yet)
-fast charge (thx to chad0989 for this), disabled by default.
you also can use the widget from chad (to place on homescreen) to toggle the fast_charge mode

while fast charge is activated you cannot connect as usb device
- added datafix script to init.d (this script is deactivated by deafult. to make it work, you have to creat a file named datafix and placed in /data/local/)

Continuing my discussion from ICS thread here. Either I effed up enabling Idle2 or running a internal Cat of kmsg is not letting my phone drop to idle . Can Idle 2 be enabled from the app or that needs to be implemented?
Edit: Got everything to work. Here is the KMSG that I got. The problem is, if I use ADB the phone doesn't activate Idle2 but i feel like making my phone cat kmsg while I'm trying to crash it might not get the whole txt? I could be wrong. Hope it provides more info.
Idle2kmsg.txt

Wait so what's the difference between deep_idle 2 and idle2? Anyways I'm going to flash it and see what's the difference!

@DerTeufel
Apparently I don't get SoD with idle2, my phone locks up. Screen Actually showed lockscreen this time when I attempted to wake it up while playing music. Sadly my computer doesn't see the device during this state. Any advice? Did you take a look at the kmsg I provided in my earlier post?

Thanks for your contribution .

Can't get to recovery?
Hello all, first time in Devil kernel.
First flash went well, I flashed and tested it was working by rebooting back into recovery. I set a few options (such as vibrate intensity) and rebooted, everything was OK (even better even, because Waze started working finally).
I did a 'touch /data/twrp' to try to enable the TWRP recovery, and rebooted, but now I'm kinda stuck at the kernel logo. Capacitive buttons do light up (but don't vibrate the phone), and I can reboot by holding all three hard buttons for ten seconds.
I noticed in the changelog that "for some reason" it takes a few seconds to start TWRP, but I waited for ten minutes (and dropped by battery 43%) before giving up. Coincidentally, now I'm getting the "android.process.media" has stopped error, waiting to see if a appdata wipe will help on that one...
Thing is, even after deleting the file I touched, it's still not letting me into Recovery (the normal CWM). Are there any hints at this? Or should I look at trying to get Heimdall working to try reflashing the kernel?

yes, i think best would be to reflash the kernel, and then try to get to recovery.

Yeah, on the thoughts that it might have been a bad flash, I did try that. Now I've downloaded the 8/1 version for testing, we'll see what results. TWRP should be rom-independent, right?
I just don't know what else I might be doing wrong. Perhaps it's reading the TWRP information from a previous version and hanging up? Oh well, I supposed it can wait.
I renamed the TWRP file from a previous kernel's version and tried to reflash, but still no go...

i think twrp is not working at the moment with jellybean. i try to fix this tomorrow.
till then, you have to go to cache and delte the twrp file from there. if this file isn't present, then please attch your /boot.txt

Ok. Somehow the Devil Kernel Config app wasn't properly deleting the file, once I used an actual command to delete it, it worked OK to be in CWM recovery.
Just for kicks, I attached my /boot.txt log.

Boot.txt is fine now

Just for clarification, doesn't the boot.txt file get overwritten each boot? So if I'm having issues getting into TWRP, and I reboot to get out of recovery mode, the boot.txt file will only give information about the current boot (not the broken TWRP)?

Yes. That's right. It would have been helpful, if you grep it with adb, while stuck. I already did this now, and it wasn't helpful

One thing that always frustrated me was the fact that there is literally no way to watch the kernel messages on the display as it boots. That's one of my most trusted debug methods on the computer: Have it show what it's doing on the console.
Of course, there is a serial port somewhere, but it's apparently not easily accessible without special hardware...
Something just occurred to me: What if we could manually load the TWRP ramdisk and chroot into it? Would that allow us to interactively watch it? or (since stuff is already loaded and junk) that may not be possible? I noticed that adb starts, but we can't get a shell, so...

There is 1.1.3 kernel uploaded.

[Kernel][01/03/2013] CoCore 4.1

This custom kernel is base on diego-ch's TWRP kernel.
I call it CoCore.
( Responsibility )
I'M IN NO WAY RESPONSIBLE OF ANY DAMAGE CAUSED BY USING THIS CUSTOM KERNEL.
( Compatibility )
This kernel works well on i9070.
I am sorry that it causes high cpu load on i9070P!
( What is needed )
* An I9070 (Andorid 2.3.6)
* Some Android experience
* Know some knowledge of how to use Android Terminal
* More patience
( Features )
TWRP Recovery 2.2.1
28 CPU Governers
8 I/O Schedulers
IO Unlocked (increased a bit speed)
Init.d Script
Custom Bootanimation
Deeper Sleep Mode
zRAM, SWAP Supported
NTFS(Read Only)
CIFS
ARM ThumbEE
ARM VFP with neon
Optimized RWSEM Algorithm
Mali GPU Tweakes/Controls
LZO Kernel Compression ( for faster boot )
Removed Useless Drivers ( for faster boot )
SLUB Memory Allocator
Automatic readahead cache size
Audio Boost*
Linaro GCC Toolchain
And many miscellaneous tweaks, it's hard to make a list for them.
Maybe i also forgot them.
A ton of new features in my updates,please Check the updated version.( See below )
( Detailed explanation )
CPU Governers Supported:
Code:
Performance, OnDemand(default), Lionheart, Powersave, Userspace,
Conservation, OndemandX, SmartassV2, Interactive, Scary, Sakuractive,
PegasusQ, Intellidemand, Lazy, Wheatley, HotPlug,
SmartAss, LagFree, BrazilianWax, InteractiveX, MinMax, SavagedZen,
Aggressive, AggressiveX, Gallimaufry, GallimaufryX, AbyssPlug, Skywalker
* To get stable scores, please use Performance to run benchmarks.
* For daily using, i recommend PegasusQ.
* Please test the governors by yourself.
* And the PegasusQ will hotplug the second cpu when screen turns off,that might cause music skip when system load is heavy.
* If unsure,please use ondemand(default)
IO Schedulers Supported:
Code:
NOOP, Deadline, CFQ, BFQ(default), SIO, VR, anticipatory, ZEN
* To get more information about governers/io schedulers, here:
http://forum.xda-developers.com/showthread.php?t=1369817
* For daily using, i recommend SIO/BFQ/ZEN
* Please choose a best io scheduler by yourself.
Init.d Script:
* Please make sure there is a latest busybox in your system.I found that init.d didn't work properly on some devices which have old version busybox.
* The init.d folder (/system/etc/init.d) must have 0755 permissions.
* If the scripts dont have execution permissions,it wont be execute automatically.
Custom Bootanimation:
* Please put the bootanimation.zip in /system/media with right permissions(0644).
* If there isn't any custom bootanimation, kernel will load Samsung official bootanimation.
DeepSleep Mode:
* Default mode is State4, i changed it to State5. Increased standby life time.
* If you use a hotplug governor,it might be unstable when you use the deepest sleep mode.
* Some users reported that ondemand works well with deepest sleep mode.
* If you mind the standby time of the phone,please give it a try.
* You can get information about CPU sleep states:
Code:
cat /d/cpuidle/stats
* To change the allowed deepest sleep mode: (e.g. Allow State6)
Code:
#echo 6 > /d/cpuidle/deepest_state
zRAM & SWAP:
* zRAM must be enabled by script/command.
Code:
mkswap /dev/block/zram0
swapon /dev/block/zram0
* SWAP must use with a SWAP partition in sdcard.
Code:
mkswap /dev/block/mmcblk1p2
swapon /dev/block/mmcblk1p2
* Because we have a large memory, the zRAM/SWAP is low activity.
* Some users said that zRAM/SWAP wont help the performance of games,they might drop more battery.
NTFS:
* Need a binary called "ntfs-3g" to read/write ntfs sdcard. Built-in NTFS feature only can read.
* Stock Android 2.3 cannot mount NTFS sdcard automatically.
Mali GPU:
* Allowed larger memory.
* Allowed larger OS memory for buffer. ( 6m -> 10m )
* L2 cache max reads tweakable
* Enabled some features in Makefile.
* Disable a big debugging checking
Audio Tweaks:
* Enabled directly rendering
* Enabled 32k_clk ( a feature of AB8500 )
* Volume Boost! ( v3.6-3.8rc,optional in v4.0 )
* Dynamic Range Enhanced! ( v3.6-3.8rc,optional in v4.0 )
( Installation )
Method 1
1. Flash the kernel which has TWRP via Odin. You can flash diego-ch's TWRP kernel, or flash "GT-I9070-Kernel-CoCore.tar.md5" in attachments.
Here diego-ch's TWRP kernel: http://forum.xda-developers.com/showthread.php?t=1873119
( flash custom kernel will increase binary counter!! )
2. Run Odin, Put the md5 files in PDA, Pit files doesn't need.
3. Only check "Auto Reboot" and "F.Reset Time"
4. Click Start to flash, wait for phone reboot.
5. Boot into TWRP, Tap Install, Select i9070_kernel_CoCore_TWRP.zip, Flash it.
And, if you have TWRP kernel already, flash the zip via TWRP directly.
Method 2 (Experienced users only)
This method will not increased binary counter, but ROOT permission is needed.
1. Get kernel.bin.md5 from i9070_kernel_CoCore_TWRP.zip
2. Put kernel.bin.md5 in sdcard
3. Run your favourite terminal app, type these codes
Code:
$su
#dd if=/sdcard/kernel.bin.md5 of=/dev/block/mmcblk0p15
4. Reboot
If you typed a wrong patition number, perhaps it will brick your phone!!!
Think twice before you hit Enter.
( Updates )
01/03/2013 Update: CoCore v4.1
Hmm,This is BETA version.
Block: Added ZEN io scheduler (Bases on noop,deadline and sio)
CPUFreq: Added Skywalker governor (FreqTable tweaked)
Mali: Increased the default l2 max reads 28kb -> 48kb
Mali: Disabled a big debugging tracking
RCU: jRCU -> TreeRCU (For better CPU/RAM throughput!)
NWFPE: Enabled ex-nwfpe
Please remove the mali l2 init.d script tweaks,guys
CoCore-mini 1.4 is at #842 post.
12/23/2012 Update: CoCore v4.0
Mali: Driver updated, re-tweak the parameters
ASoC/ab8500: Driver updated
NET/conf: Enable HSTCP(high-speed tcp),Westwood+,Veno,Hybla,YeAh configs. Cubic(stock) conf is default.
Block: Set BFQ as default io scheduler
Block: Automatic readahead cache size limit (depend on the size of your sdcard)
Block: Re-tweak SIO/VR/Deadline for flash nand devices
MM: SLQB -> SLUB
SCHED: Remove fair_sleepers, revert the parameters back to stock
MISC: Remove a ton of juck!!!, Highest complie optimization level, boot faster(compare to old versions,8800ms~9100ms now)
PS.
The cifs.ko and smbfs.ko have been put out ramdisk.They will be installed to /system/lib/modules (for faster boot)
And i forgot the changes,see my source on my github.There is a changelog.
To change the net configs:
Create a new init.d script:
Change the 'highspeed' to other confs.
Use `sysctl -a | grep cubic` to know what conf you can change to.
`ping` is the simple way to test whether the conf you use fix you or not.
For me,i am using highspeed now. If unsure,keep default(Cubic)
Code:
#!/system/bin/sh
sysctl -w net.ipv4.tcp_congestion_control=highspeed;
I have set the mali l2 cache back to 28kb by default.
To set it to 48kb(max).Use an init.d script.
Code:
#!/system/bin/sh
echo 0x00000030 > /sys/module/mali/parameters/mali_l2_max_reads;
The game fps should be improved a bit,
The values you `echo` must be HEX
BUT,if it doesnt or feels lagged,remove this script.
For me,48kb works well.
The volume++ version is volume boosted. (Someone requires this)
The lagged sound will be increased,too!
12/09/2012 Update: CoCore v3.9Beta8
This is BETA VERSION!!
CpuFreq: Added AbyssPlug (Base on OnDemand+Hotplug)
Mali: Increased the priority of OSMEM (5 -> 1) (See the dmesg)
Mali: Unlocked mali_l2_max _reads in sysfs (You can tweak this parameter now) (Dont set over 48)
(If you find a good value,please share with us!)
Mali: Misc tweaks
Kernel/hz: Fix the defconfig issue (Thanks! @hafidzduddin)
Net/SCH: Reverted back to stock (To experiment the latency of enabling mobile data)
Makefile: More optimization flags
PS.
The Mali parameters are in /sys/module/mali/parameters/
Use scripts/terminal to set them.
12/07/2012 Update: CoCore v3.9Beta3
This is BETA VERSION!
J4FS: J4FS driver works! Bugfree now!
CpuIdle: Revert the ApDeepSleep to stock,and added ApSleep++ custom state
(ApSleep++ and ApDeepSleep only works with non-hotplug governors,e.g: ondemand)
(New sleep state is disabled by default.You can enable them by yourself,if you prefer longer battery.)
CpuFreq: Added Aggressive, AggressiveX, Gallimaufry and GallimaufryX (These are optimazed version of Conservation/OnDemand)
CpuFreq: Fix a hotplug bug of PegasusQ
FS/SYNC: Removed Dynamic Fsync Control,added Ezekeel FSync Control
ASoc/ux500: Raise the pcm buffer size to MAX
NET/Scheduler: Re-tweaked, to experiment the latency of mobile data
Unknown: Fix the touchscreen sudden lost response (According to my using these days,it has been happended again!)
PS.
The FSYNC is enabled by default.Disabling FSYNC can improve IO performance.
In AnTuTu IO Test: Enabled: 350-400 Disable: 540-560
But disabling FSYNC can cause losing data!! It is at your own risk!!
Check the TIPS part to get how to disable it.
12/02/2012 Update: CoCore v3.9Beta1
This is BETA version, at #344 post.
12/02/2012 Update: CoCore v3.8.6rc
ASoC/ab8500: Use another gain mode in order to fix the terrible audio issue.
Sched: Reduce the latency of CFS Scheduler
PS.
The dyn_fsync will casue screen lag when you turn off the screen and there is a heavy io load.
If there isnt any heavy io load,it goes normally.
If you hate this,see the Tips part (#2 post) to get HOW TO disable dyn_fsync.
12/01/2012 Update: CoCore v3.8rc
CpuFreq: Tweaked the freq table of PegasusQ
Blcok: Updated BFQv1 -> BFQr2-1,Fixed the latency of BFQ issue. (BFQv5 is incompatible with Linux 2.6.35)
Sched: Tuned the patamerters of CFS scheduler (Use ThunderBolt's)
Sched_features: Enable Fair_Sleepers,Disable HRTICK
Mali: L2 cache max reads -> 48kb,Fix the mem leak issue.
NET: Set WestWood+ as default CONFIG
fs/sync: Added Dynamic FSync Control
(Improve IO performance greatly.When the screen is on,fsync is off.When the screen is off,fsync is on.)
ASoc/ab8500: Fixed the FMRadio volume balance issue. (Thanks @shut_down)
MISC: Removed a TON of JUNK!!!,And added a workaround to flash kernel quickly.
PS.
The benchmark screenshot is in the #304 post.
How to disable DYN_FSYNC? Check the TIPS part. (#2 post)
What is the flash kernel workaround?
In TWRP,use the Terminal fucntion,SELECT the folderr which has a kernel named "kernel.bin.md5",Start the Terminal,
And just type "fkernel"(No quotes),it will flash the kernel.bin.md5 automatically.
And i found that V(R) is a good io scheduler too.
The BFS CPU Scheduler is incompatible with our kernel.I am about to introduce this in the JellyBean kernel.
11/25/2012 Update: CoCore v3.7
RamDisk/TWRP: Added a temporary workaround to mount emmc(internal memory)
Block: SIO io scheduler updated. (2012 version) (Thanks @hafidzduddin)
CpuFreq: Fixed the name issues of governors (SetCPU cannot tune the parameters of governors, now fixed)
CpuFreq: Added LagFree, BrazilianWax, InteractiveX, MinMax and SavagedZen governors
(New governors havent been tested fully!If unsure, PegasusQ is recommended.)
I have tweaked the freq tables of most governors.
Mali: L2 cache max reads: 48kb -> 44kb , FPS increases (1-8fps) in simple scenes.
(Reserved 4kb for buffering, perhaps it will fix the sudden lag in games)
Sched: Fix SAMSUNG source code errors
Sched: Added AutoGroup Scheduler v4
Net/Sched: Re-changed the scheduler of net
android/logger: Reduced the logger size
ASoc/ab8500: Headset Volume adjusted, Dynamic Range enhanced! (i recommend using PowerAMP/RockBox)
PM(PowerManagement): Added a new feature, Operating Performance Point (OPP) Layer library
MISC: Disabled something useless(for faster boot),
Added GenLock API, MM&DMA hacked,
Added a new feature DM_CACHE,
more GCC optimizations in MakeFile
PS.
Dont use high volume to listen to music over 1 hour, it it not good for your ears.
Just reduce some volume.And i havent gained the speaker volume, dont worry.
The TWRP has some grapics issues when entering the emmc folder(it happends soemtimes, not always),
if it happended just tap back button and enter again.
(Some guys required this becaues them havent an external sdcard! )
And about the SetCPU issues. If you cannot tweak the parameters of some governors,
go to /sys/devices/system/cpu/cpufreq/(governor_name)/, you can tweak them here.
Make a script to tweak them quickly.
I think there is no point in updating to 2.6.35.14, because it updates a lot of useless drivers.
11/18/2012 Update: CoCore v3.6
Block: Added anticipatory io scheduler
CpuFreq: Added HotPlug and SmartAss governors
CpuFreq: Tweaked SmartAss and SmartAssV2 freqtable in order to match our device
Kernel: Adjusted many parameters
Lernel: Built with optimized compiler options
Sched: Added Fair_Sleepers feature,
disabled Gentle_Fair_Sleepers feature,
enabled HRTICK feature
MM: Increased Min readahead 16k -> 32k
JHash: Added JHash v3 speed tweak
Mali: Use another timestamp mode
ab8500/asoc: Headset volume gain boosted! (Sounds perfectly.My ears will be satisfied with i9070+Edifier H850. )
11/11/2012 Update: CoCore v3.5
Kernel: Revert LZO compression ( LZO is the fastest, but it makes kernel largest )
Kernel: Removed some bad tweaks
Kernel: Compile with Linaro GCC 4.4.5 ( The final version of Linaro GCC 4.4 series )
Ramdisk: For power saving, cifs.ko and smbfs.ko will not be loaded by default
Block: SIO, V(R) and Deadline io scheduler tweaked ( Better IO throughput )
FS: EXT2, EXT3 and EXT4 speed up
JHash: Updated to JHash v3
Sched: Enabled HRTICK
RCU: Added and use JRCU
TCP: Change TCP_Config to VENO ( Faster on wireless network ), and enabled HSTCP ( High-speed TCP )
NET: Net schedulers tweaked, in order to work with VENO config
NET: Introduce u64_stats_sync infrastructure
MM: Added vzalloc() and vzalloc_node() helpers
MM: Added and use SLQB memory allocator
MM: Added fudgeswap
SYNC: Added synchronization framework
BCM4330(WLAN): Enabled PM_FAST mode in standby
CGroup: Enabled FREEZER feature
PS. And many misc tweaks.
And i added some modules in /lib.
I tweaked mali parameters again (MEM -> 48MB OSMEM -> 8MB).
Because i find that when the memory is too big, it feels lag.
According to my test, in simple scence, fps increases (1-2fps); in complex scence, fps reduces (1-2fps).
But UI is faster in low frequencies! ( i often use signle core at 800Mhz )
10/28/2012 Update: CoCore v3.1
Mali: Fixed the fps issue.
RCU: Use Tiny-PREEMPT RCU (To reduce memory footprint, and feel more smooth)

The source code is available on my github now.
If there are any issues, please report.
And if you like my work, Press THANKS Button Please. It encourages me.

( Tips )
1. For performance, please remove libGLES_android.so in /system/lib/egl to disable weak CPU rendering.
2. Flash your kernel quickly via Ternimal.
Creat a new file (named `ddkernel`) with RootExplorer.
Write these codes:
Code:
#!/system/bin/sh
source=`busybox realpath kernel.bin.md5`;
echo "DD: Flashing $source";
busybox dd if=kernel.bin.md5 of=/dev/block/mmcblk0p15;
Save , and set right permissions (0777), put it in /system/xbin
Now, you can `cd` to the folder where stores `kernel.bin.md5`, and use `ddkernel` command to flash kernel.
3. Mount your NTFS sdcard
Firstly, you need a binary called "ntfs-3g". Put this binary in /system/xbin
Open your terminal app.
Code:
mkdir sdcard-ntfs
ntfs-3g /dev/block/mmcblk1p1 /sdcard-ntfs
4. My sysctl.conf
Code:
vm.dirty_expire_centisecs=3000
vm.dirty_writeback_centisecs=500
vm.dirty_background_ratio=40
vm.dirty_ratio=80
vm.vfs_cache_pressure=1
vm.highmem_is_dirtyable=1
To use this file,you must have installed busybox,and put this file in /system/etc
Go to /system/etc/init.d/,create a new file(Any name you like),write this(Remember to set right permissions(rwxrwxrwx) of new file):
Code:
#!/system/bin/sh
busybox sysctl -p;
Now your sysctl.conf will be loaded automatically in every boot.
5. How to disable Dynamic FSync Control? (CoCore v3.8-v3.8.6 ONLY)
In your /system/etc/init.d/,create a new file
Code:
#!/system/bin/sh
echo 0 > /sys/kernel/dyn_fsync/Dyn_fsync_active;
Now,this function will be disabled in every boot.
6. How to Control the FSYNC? (CoCore v3.9+)
In your /system/etc/init.d/,create a new file(any name you like)
Code:
#!/system/bin/sh
# Disable FSYNC
echo 0 > /sys/class/misc/fsynccontrol/fsync_enabled;
# Enable FSYNC
#echo 1 > /sys/class/misc/fsynccontrol/fsync_enabled;
Or you can control the FSYNC via terminal realtime.

Good work!
Just I have a request
Can you try this on JetMOD and tell me if Power menu options of Reboot, and Reboot recovery works?
I am planning to ship this kernel in next update of JetMOD

Looks nice. Got the I9070 today. Will test it out soon.
Btw, which users are working on CM ? I would like to contribute. I have already forked hackbob's source. Will look into it sometime later.

Edit : Removed. Double post.

No, there isn't. Triangle Away only works on ICS/JB
When get JB source code, we can have a try.

tnx allot dude, i`m sad that i am at the office and can`t test your kernel :|

I have made CWM. Should i include it in the boot image and flash ?
I dont see any zip which includes the .img format..

after flashing it by TWRP, it stuck on boot logo :S
i was using jetmob rom before, and need to restore the backup.. i'v tries twice, and same boot logo stuck..

Great, You have made CWM for i9070?
i9070 kernel format is zImage, not boot.img.
You can fork the kernel repo of diego, replace the recovery files, and complie kernel.
Put it in dev thread.
We will test it.

Try to delete/rename the init.d folder in /system/etc.
Some scripts of JetMOD stuck booting.
Please report me if it works.

i have flashed your kernel and i am happy to see that drop of fps is gone, the rest is working splendit as well, tnx again

installing these kernel?

hi cocafe.
your custom bootanimation work?
in my kernel custom bootanimation loops never stop.
i use diego-ch ramdisk
im a user of galaxy ace 2

What is that CPU/b2r2 rendering?
Is that audio tweak included without flashing " optional scripts? If I do not want to enable "Deepest Sleep" and "Mount" from optional scripts zip, is it enough to delete them from the zip?

Yes, several weeks ago, i fixed that loop bug.
You can check the ramdisk of my kernel. There is a small workaround in post_boot.sh.
Here the method:
in init.ux500.post_boot.sh, write these code
# fix custom bootanimation loop
sleep 4;
bootani=`ps | grep bootanimation | cut -b 10-16`;
kill $bootani;

[INACTIVE][KERNEL] SKZ Custom Kernel for Evervolv 7.1.x [1890KHz CPU/320MHz GPU]

Note that while you can download the most current kernel from the links below, this thread is no longer being updated. Go to Devs-base for the active user thread. Watch this for details.
Here's a custom kernel for you all to try out. It should work with the Evervolv nightlies. Not tested with other ROM's.

NOTICE: This kernel can be overclocked over the standard Touchpad voltage regulator settings. It may or may not be stable for your particular Touchpad. I am not responsible in any way for anything that occurs as a result of your use of this kernel. You agree that by flashing this kernel, you are doing so with a full understanding that you assume full liability for any and all issues that may arise from doing so.
Click to expand...
Click to collapse
This kernel must be flashed from recovery (DO NOT USE TP TOOLKIT!) No need to clear caches, format system, or any other preparation. Flash and boot. You can set the kernel parameters from the EVToolkit, but I highly recommend Kernel Adiutor for more detailed and granular control of settings. If you don't like it, recover by reflashing your base EV ROM.
Here's a few facts:
CPU Overclockable to 1890KHz
Level 2 frequency boost to 1890KHz
Stepped 2D & 3D GPU OC up to 267 MHz and 320 Mhz, respectively
Additional governors and schedulers
Use Kernel Adiutor for tuneable parameters in the kernel
READ HERE FOR INFORMATION ABOUT GOVERNORS AND SCHEDULERS: Guide Link
NOTE!: The kernel has stability up to 1836 KHz, so if you decide to try the higher frequencies or change the cpu voltages, be sure and UNSET THE 'APPLY AT BOOT' option in your kernel tuner app. If your tablet can't handle the higher frequencies or voltages, it will either freeze or reboot. If it freezes, you will have to do a hard boot (hold power and HOME key simultaneously until it reboots). It should revert back to the default frequency of 1512 KHz max, 384 KHz min., but if it doesn't, Kernel Adiutor (KA) has a delay in setting the options. Get into KA as soon as you can after it reboots and set the CPU options to a stable setting.
Download links. No system/full wipes or cache clearing required.

Yes.

Thanks Shumash. If you wish to return to stock EV kernel you do a full wipe and reflash the ROM?

No need to do a wipe since only the kernel will change. There is another way to do it if you know your way around, i.e.,
Before flashing the SKZ kernel, copy the uImage.Evervolv file in /boot to a location on your 'sdcard'.
Flash the SKZ kernel
If you decide to restore the original EV kernel, delete the uImage.Evervolv file in /boot
Copy the saved copy of uImage.Evervolv on the 'sdcard' to /boot.
Reboot and stock kernel will be restored (any settings you made while in the SKZ kernel will be lost).

Nice thanks Shumash :highfive: I'm going to try this out
Update:
Checkout the performance boost with the SKZ kernel @ 1836! Looking good Shumash:good:

Note: Tested with Antutu Benchmark here:

[SKZ Update] 09 DEC 2016
Update available.
CHANGELOG
Code:
-> 09DEC16
- Tuned Smartmax_EPS governor for improved Touchpad performance
- Add dancedance governor (very smooth and fast, good battery performance. I love it!)
- Add hyper governor (based on conservative with some smartass features)

Are there any details on which versions of android this will work with, e.g., if we want to use it with android 4.4.4?

Nope. That's why it's stated for EV. You just need to try it out and see. Keep in mind that other ROM's name the uImage as cyanogenmod or AOKP, etc., and this kernel won't work unless renamed to match the kernel it replaces. Report back for others

Has anyone tried the 12/9 kernel over the 12/9 nightly? I got boot error. Rom worked fine before I tried the kernel. I just reflashed from and it works fine.

Crashes with Antutu Benchmark when OC'd

I was able to boot fine but when I OC to 1836 and tried the dancedance governor I rebooted in antutu benchmark(twice now). Been trying to fetch some logs with the Evervolv bug reporter but it doesn't seem to be working for me. Tested again, stock speeds, default governor and I was able to complete Antutu Benchmark.
Shumash be advised that the 12/9 nightly has moved up to Android 7.1.1, not sure if that's an issue.

Works fine for me (including 7.1.1), but I'll try and see if I can duplicate the Antutu issue. Did you try dancedance at a lower clock?

Results, 7.1.1 (home rolled on 12/10), 1836 MHz, dancedance governor, fiops scheduler, 320 gpu.

Yes lower clocks were OK but the max overclock was the problem for me too. Going to test out the newest version of the kernel with the latest nightly and I'll report back thanks:highfive:

I redownloaded my kernel zip and the latest Evervolv 12,11 nightly but I'm still experiencing crashing with Antutut benchmark when the CPU is set to 1836. It always crashes in the same place after the video tests @ Image processing blur load screen. However when I set the CPU to 1782 it finishes the test every time and gets a great score.
Note: using the default governor while testing

As you are aware, some 'pads can OC, some can't. Mine can (with the default governor, 19793).

Mine could also oc to 2.1ghz back in jellybean but my phone could not reach it own max oc, it mostly depend of if you got a good SoC batch but they required more cheaper one for metting the demand or a bad one which was intended for getting use has lower end. That mostly the case with PC CPU but since all mobile device was underclocked by default, it did not make any difference for end user because of the heat and energy consumption of full clock or overclock.
Great to see the Tenderloin still alive with at less a single custom roms but seeing a custom kernel on rolland's video on my youtube feed made me fell like "wtf, i need to get updated on that device devellopement, it's really happening ! ". Thank shumash, my tenderloin might not be my main tablet anymore (buyed an Surface Pro 3 and found a Nexus 7 2012 in the dump) but's still a very good device for light stuff or has a second screen in bed for a guide in a game. You are amazing like always.
