Changelog:

newer changelog can be found here:
http://www.hellybean.com/ics.html

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
- automated symlinking from data to system: if one wants to free up some space at /system, without removing an app completely, just copy it from /system/app to /data/sys-parts/app (create the folder if not there), and reboot. during reboot, the app from system gets deleted, and the app from /data/sys-parts/app gets symlinked to system. this is working for almost every app, but i don't recommend doing this with apps, needed for android to work (framework, media provider, settings,...)

IDLE2 can be enabled with the following command:
echo 0 > /sys/module/cpuidle/parameters/idle2_disabled
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 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:
This kernel is for use with ICS only, if you are looking for a kernel, running on teamhacksung cm10 build, visit my jellybean kernel thread[/url]
- 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)

Quote:

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

- 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_...e_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 10.06.2012:
cwm recovery:
- fixed mounting of external sd card to pc

kernel:
- picked two commits from linux 3.0.32 (avoid a possible memory leak, small fix to ext4 driver)

- prevent phantom key presses (from tk glitch)

changelog 24.05.2012:
- Smooth_ui included to ondemand, conservative, smartass, lulzactive, lagfree and lazy governor (only one setting for activating/deactivating it in general)
- 3 cpu governor presets (smooth, normal, powersave) for ondemand, conservative, smartass, lulzactive, lagfree (only one setting for switching the mode in general)
- no need for activating/deactivating of selective live_oc anymore --> just change target low and target high
- BLX back in
- fixes to devil idle to be more stable while in call

- added frontpage
- added cleancache
- added fudgeswap (thanks to ezterry and faux123)

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.

Quote:

you also can use the widget from chad (to place on homescreen) to toggle the fast_charge mode
https://play.google.com/store/apps/d...stchargewidget

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/)
- reworking and cleaning many parts to get more ram, speed, and stability

05.03.2012:
- updated sio i/o scheduler to latest version
- small updates to ondemand and conservative governor from linux 3.2

- I/O-less dirty throttling completely backported from kernel 3.2
- Ext4 with 3.2 patches
- Proportional Rate Reduction for TCP - by Google
- USB Host V 4

19.01.2012

- virtual buttons in cwm recovery not working

i9000(b) specific:
nothing

How to:
Quote:


Quote:

you can change ram setting by doing the following ( to make these settings even stick after power off, you also have to echo the same value to to /data/local/devil/bigmem):
echo 1 > /sys/kernel/bigmem/enable (this gives you xl mem of 391 mb)
echo 2 > /sys/kernel/bigmem/enable (this gives you bm mem of 403 mb (this is breaking 720p))
echo 0 > /sys/kernel/bigmem/enable (this gives you cm9 default mem of 378 mb)
you have to reboot to make changes work


Quote:

With setting this, your desired swap mode gets automatically applied at boot time. For swap, you have to create a swap partition at your external sd card before
echo 1 > /data/local/swap_use (for using swap partition on external sd card, you have to create this partition before)
echo 2 > /data/local/swap_use (for using Zram, no other modifications required)
you have to reboot to make changes active. You can't use swap and Zram at the same time


Quote:

These are the settings for devil idle:
activate automatic:
echo 1 > /sys/devices/virtual/misc/devil_idle/bus_limit
permanent on:
echo 2 > /sys/devices/virtual/misc/devil_idle/bus_limit
deactivate
echo 0 > /sys/devices/virtual/misc/devil_idle/bus_limit_automatic

Quote:

to set different voltages while screen off (this only is working, if devil idle automatic mode is activated)
this is an example, how to apply screen_off arm voltages:
echo 1450 1400 1350 1275 1075 975 875 800 > /sys/class/misc/customvoltage/arm_volt_screenoff

this way, it is possible to undervolt while screen off, but overvolt and overclock while screen on

for now, the int voltages can not be changend

Quote:

set freq limits while screen off (min and max freq)
enable the limits:
echo 1 > /sys/devices/virtual/misc/devil_idle/user_min_max_enable
disable:
echo 0 > /sys/devices/virtual/misc/devil_idle/user_min_max_enable

set values to be applied if activated:
echo 100000 > /sys/devices/virtual/misc/devil_idle/user_min
echo 800000 > /sys/devices/virtual/misc/devil_idle/user_max

both are independent from devil_idle, and get applied when screen turns off
by default 100 and 1000 mhz are set.
values which can be put here are all "stock" freq (without live_oc level) multiplied with 1000. live_oc values get applied automatically.



Quote:

to set responsiveness_freq, up_threshold_min_freq or sleep_multiplier for ondemand and/or conservative governor, you have to do it like this:

echo VALUE > /sys/devices/system/cpu/cpufreq/ondemand/VARIABLE_NAME
and
echo VALUE > /sys/devices/system/cpu/cpufreq/conservative/VARIABLE_NAME

example:
echo 400000 > /sys/devices/system/cpu/cpufreq/ondemand/responsiveness_freq
echo 50 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold_min_freq
echo 5 > /sys/devices/system/cpu/cpufreq/ondemand/sleep_multiplier

up_threshold_min_freq is disbaled by default for conservative governor
(to disable it for ondemand you have to set up_threshold_min_freq to 100.


Quote:

switch between wifi PM_Fast and PM_Max mode (Pm_Fast = better signal, PM_Max = better batterie, default is PM_Max)
echo 1 > sys/module/bcmdhd/parameters/uiFastWifi (pm_fast)
echo 0 > sys/module/bcmdhd/parameters/uiFastWifi (pm_max)

Quote:

user interface to disable fsync (this gives more performace, at the risk of data loss on a crash, taken from ezekeel), default is on, to be safe
echo 1 > /sys/devices/virtual/misc/fsynccontrol/fsync_enabled (fsync enabled)
echo 0 > /sys/devices/virtual/misc/fsynccontrol/fsync_enabled (fsync disabled)


Quote:

to set the values for vibrator intensity:
echo value > /sys/class/timed_output/vibrator/duty (where value is between 20000 and 43640)
if you want the changes to be applied at boot, you have to use one of the presets from recovery, use an init.d script, or:
echo value > /etc/devil/vibrator (where value is between 20000 and 43640)


Quote:

activate fast charge: echo 1 > /sys/kernel/fast_charge/force_fast_charge

deactivate fast charge
Quote:

echo 0 > /sys/kernel/fast_charge/force_fast_charge

you also can use the widget from chad (to place on homescreen) to toggle the fast_charge mode
https://play.google.com/store/apps/d...stchargewidget

while fast charge is activated you cannot connect as usb device

Questions and Answers:


Q: What the hell are all these governors?
A: here you should find the answer: http://forum.xda-developers.com/show...php?p=19846297

Q: What's a good setup for live_oc??
A: No one knows. Every phone is different. It seems like the folling setup is running well for some (many?) users. If you get reboots with it, you have to find the setup for yourself.

low freqs could possibly be tweaked harder but stability was my fist goal

Q: How can I set up swap?
A: Take a look at this thread: http://forum.xda-developers.com/show....php?t=1610835, and especially at this post:
http://forum.xda-developers.com/show...1&postcount=83

Q: What is Touchwake? Can you explain it?
A: With Touchwake, the touchscreen still recognices your fingers, after turning off (for a predefined time (NSTools)). For a detailed explenation, take a look at Ezekeel's thread: http://forum.xda-developers.com/show....php?t=1239240


Q: How can I make Voodo Color settings been saved after reboot?
A: You have to use Voodoo Pro App, because of changes between Gingerbread and ICS, and only the Pro app is updated till now.


Q: Which is the best IO Scheduler?
A: I think SIO and V(R) are the fastest.


Q: How can I enable DeepIdle/Live_Oc?
A: You have to use NSTools. You find it on market. It's free.


Deep Idle Questions:
Q: How can I activate the deep idle stats?
echo 1 > /sys/class/misc/deepidle/stats_enabled

Q: What's the meaning of TOP=Off and TOP=On when I look at the Deep Idle status?
A: When TOP=Off is used, the best powersaving state is used. TOP=ON will be shown, when bluetooth or gps are running.


Q: In Idle status I only see TOP=On. What's wrong here? I don't use Bluetooth or Gps.
A: You have to flash the modded framework-res.apk, because ICS does not fully deactivate bluetooth by default. Even if you never use it.


Q: Idle Stats only are showing Idle, but no Deep Idle. Why?
A: An App is preventing the use of Deep Idle. At first, you should try closing the cam, running in the background. Also rebooting should solve this problem.


Q: What is fudgeswap?
A:
Setting this to a very large positive number will indicate swap ought
to be fully used as free (and will slow the system down)

smaller numbers will allow you to put some pressure on SWAP without
slowing the system down as much.

small negitive numbers will allow the system to be faster at the same
minfree level.

default is 512 to give a very little bit of pressure to use some swap
but this can be modified at runtime via:
/sys/module/lowmemorykiller/parameters/fudgeswap

why new thread?

damn it, I'm on CM7....
and I want to try your kernel!

CM7 seems to be the stables and fastest for now :\

A very good changelog
I'll give a try when it's done.

@orenzah : Did you try CM9 or SlimICS (for example) ?
Because, I think ICS is really stable for daily use.
For the new thread, I think it's because, now it's Devil3 and not Devil2 anymore.

For the new thread, I think it's because, now it's Devil3 and not Devil2 anymore.

because it is devil3, i wanted to have a third post for infos, and the other already got really big...

Scheduler
I just flashed Devil3, thanks. Question though - in devil 2, my scheduler was SIO by default, as listed in the feature list, and I always left it like that. After flashing devil3, it's now CFQ. I haven't run benchmarks yet or anything, but noticed the feature list for Devil3 still says SIO by default. Is the default now changed to CFQ? I'm not sure which is the best scheduler to run - CFQ, SIO or VR? I will benchmark, just wanted to hear recommendation as well.

Tx!
