Hi guys. As you may have noticed around people have been using an 'uncapped' version of Darch's Kernel source. The Kernel inside of the CM6(including nightlies) is capped at 691 as to allow anyone and everyone the ability to boot.
But what if you're a self-proclaimed speed demon whose hero is capable of high frequencies and enjoys insanely high MFLOPS and crazy high Quadrant scores?!
Well guess what!?
This kernel is for you.

[email protected] 12/22/2010 *NEW*
Commits: https://github.com/Decad3nce/htc-kernel-heroc/commits/heroc
NEW Maintenance update. Reverted VM tweaks.
Kanged erasmux frequency table. Fixed stepping and QCT CDMA radio fixup
Included 06tweaks script that configures kernel and overwrites the overwrite to scaling_governor in CM6
Revised a few low level configurations in the script regarding VM
All frequencies(except 480mhz) are on the same PLL (PLL 2).
A lot of updates to smartass cpu governor from Erasmux
Updates on the lowmemorkiller driver from AOSP
Backport smd rpcrouter from 2.6.35 to (hopefully) solve problem with Auto-answer mode - Erasmux
Reverted every usleep and msleep integration
Fixed i2c errors
Set smartass cpu governor as default, and renamed kernel (DecaFuct)
Changed sleep mode back to HTCs recommendations

Specific Kernel Contributors via github
KingKang, this is how you give credit and show your source via GPL and on Github.
I'll add in more explanations to things as time progresses and as I merge in more of my commits that I have locally.
How to install:
Place the downloaded update.zip at the root of your sdcard. Then boot to recovery mode, wipe dalvik, and flash it. Your ramdisk will remain intact and unchanged, but your kernel will be replaced.
You MAY need to wipe dalvik cache if you're having strange problems.
Please nandroid first, that way you always can go back after you hate me.

How to compile!
This guide is written for debian based linux
Retrieved and modified from the CM Wiki which can be found here: http://wiki.cyanogenmod.com/index.php?title=Building_Kernel_from_source
Firs things first, you'll need to install the development support packages for 32bit/64bit via aptitude or other method:
Code:
git-core gnupg sun-java6-jdk flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev
Then you'll have to retrieve the repo script, move it to /bin and make it executable:
Code:
mkdir -p ~/bin
curl http://android.git.kernel.org/repo > ~/bin/repo
chmod a+x ~/bin/repo
(You'll have to reboot after this step)
Next up, I'd recommend that you repo sync the CM android repository from http://www.github.com/CyanogenMod/android. This massive repository contains the tools necessary for rolling a kernel. (You can also repo sync the AOSP repo, if you want to build Vanilla Android).
Code:
mkdir -p ~/android/system
cd ~/android/system
repo init -u git://github.com/CyanogenMod/android.git -b froyo
repo sync
Then you'll want to export the cross compiling toolchain:
Code:
export CCOMPILER=${HOME}/android/system/prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin/arm-eabi-
This first process will take around ~1-2 hours for full completion, grab yourself a sandwich or go make fun of aosp or something.
Next up, you'll want to retrieve the htc-kernel-heroc source from git!
You'll need to create a directory so you can keep track of your active kernels, and then you'll begin to clone the repository:
Code:
mkdir android-kernel
cd android-kernel
git clone git://github.com/Decad3nce/htc-kernel-heroc.git
(this might take a few minutes)
You now have the kernel source on your computer! Now we'll quickly run through the basics.
I set up a script for easy compilation, but you'll have to modify it a bit after you clone the repo.
(while in android-kernel)
Code:
cd htc-kernel-heroc
nano make-kernel.sh
You'll want to change the path to the CCOMPILER, to wherever it is on your PC. If you followed this guide, you'd edit the first 2 lines:
From:
Code:
CCOMPILER=~/android-cm/prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin/arm-eabi-
To:
Code:
CCOMPILER=${HOME}/android/system/prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin/arm-eabi-
Save, close out and we'll begin compiling!
Simply, if you want to compile the kernel with the defconfig, you'll just run
Code:
./make-kernel.sh DC
(This will write the defconfig to .config)
then just:
Code:
./make-kernel.sh K
This might take a good 10 minutes(depending on your set up) but after it's all set and done, you'll have the zImage located in arch/arm/boot/. So we'll grab that, and either throw it in the AnyKernel update.zip OR you might want to couple it with a ramdisk and create a boot.img.
Regardless, if you want directions on splitting a boot.img, look HERE.

Technical Details
smartass governor - is based on the concept of the interactive governor.
I have always agreed that in theory the way interactive works - by taking over the idle loop - is very attractive. I have never managed to tweak it so it would behave decently in real life. Smartass is a complete rewrite of the code plus more. I think its a success. Performance is on par with the "old" minmax and I think smartass is a bit more responsive. Battery life is hard to quantify precisely but it does spend much more time at the lower frequencies.
Smartass will also cap the max frequency when sleeping to 352Mhz (or if your min frequency is higher than 352 - why?! - it will cap it to your min frequency). Lets take for example the 528/176 kernel, it will sleep at 352/176. No need for sleep profiles any more!
Click to expand...
Click to collapse
I'm still only maxed out 691!!!!
That means that SOMETHING(probably the ramdisk) is overwriting the scaling_max_freq.
You can manually change it via:
Code:
echo "768000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
MY GPS DOESN'T WORK!!! AHHHH!!!
First, try this: Here
Relax, chances are you've tweaked your CFS, either with the Battery Tweak or manually
Fix it:
Code:
mount -t debugfs none /sys/kernel/debug
echo "NORMALIZED_SLEEPER" > /sys/kernel/debug/sched_features
echo "NEW_FAIR_SLEEPERS" > /sys/kernel/debug/sched_features
How do I change my cpu governor
First, list all the available scaling governors:
Code:
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors
Then, echo the name of the governor to scaling_governor:
Code:
echo "nameofgovernor" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
How do I utilize the Diag Function?
hotaru said:
install DmService.apk.
Code:
echo 11>/dev/qct_diag_enable

What is msmsdcc_fmax ?
The msmsdcc_fmax is literally "The maximum frequency (in Hz) used by the SD controller"(http://www.androidonhtc.com/wiki/Boot_Options)
Killing the powersave also makes it stick to the fmax setting, without having to 'ramp up' over time.
Got a reboot?
Please grab the last_kmsg from the kernel and upload it so I can see what's causing it
Code:
adb remount
adb pull /proc/last_kmsg last_kmesg.txt
What is the 'Interactive' CPU Governor:
This governor is designed for latency sensitive workloads, UI interaction for
example.
Advantages:
+ significantly more responsive to ramp cpu up when required (UI interaction)
+ more consistent ramping, existing governors do their cpu load sampling in a
workqueue context, the 'interactive' governor does this in a timer context, which
gives more consistent cpu load sampling.
+ higher priority for cpu frequency increase, rt_workqueue is used for scaling
up, giving the remaining tasks the cpu performance benefit, unlike existing
governors which schedule rampup work to occur after your performance starved
tasks have completed.
Existing governors sample cpu load at a particular rate, typically
every X ms. Which can lead to under powering UI threads when the user has
interacted with an idle system until the next sample period happns.
The 'interactive' governor has a different approach. Instead of sampling the cpu
at a specified rate, the governor will scale the cpu frequency up when coming
out of idle. When the cpu comes out of idle, a timer is configured to fire
within 1-2 ticks. If the cpu is 100% busy from exiting idle to when the timer
fires then we assume the cpu is underpowered and ramp to MAX speed.
If the cpu was not 100% busy, then the governor evaluates the cpu load over the
last 'min_sample_rate' (default 50000 uS) to determine the cpu speed to ramp down
to.
There is only one tuneable for this governor:
/sys/devices/system/cpu/cpufreq/interactive/min_sample_rate:
The minimum ammount of time to spend at the current frequency before
ramping down. This is to ensure that the governor has seen enough
historic cpu load data to determine the appropriate workload.
Default is 5000 uS.

I WANT 490+ on Quadrant Scores!!!!
I don't recommend doing this at all, but if you feel the need to show off:
1. Flash the BFS kernel up top
2. Run this in shell
Code:
adb remount
adb shell
echo "0" > /proc/sys/vm/overcommit_memory
echo "5000" > /proc/sys/kernel/rr_interval
echo "90" > /proc/sys/kernel/iso_cpu
echo "cfq" > /sys/block/mtdblock3/queue/scheduler
echo "10" > /proc/sys/vm/vfs_cache_pressure
3. Overclock yourself to max 768 with oc widget
4. Run Quadrant until you feel that your ego is stroked enough.
5. ????????
6. Profit.
Personal Modded collin_ph BatteryTweak V2
Changes
Added Temperature Management system.
Integrate a simple way to override frequencies on based on battery temperature. Works great, will need a bit of polish later down the line.
No need to echo frequencies twice during polling. So don't allow the regular frequency changes during override. Also add MinOverrideFreq as a customizable, which allows us to do a check between min and max to not have any problems. Also remove last trace of LEDfix
Fix MaxTempEnable. Previously, trying to set n caused no change. Probably due to Android being homo in shell. Everything works now.
Use interactive scheduler as default. Change min frequency to something that actually exists on the freq table.
EITHER USE THIS OR OC WIDGET. SetCPU still has way too much overhead IMHO for what it's uses are.

Yep, I've been using Beta7 myself, everything works fine. I might make a tweaked Beta10 with the updated fixes that has presets fro 710 and 768 sometime this week.
So aside from being uncapped at 691mhz, what other benefits does it get from the changes you made?

Ok, so what I take from that post is that it will increase the general speed of the device, as well as possibly save battery by "underclocking (if you will)" the SD card controller and increasing the efficiency of the task scheduler? Awesome.
My phone doesn't run well @ 768 so I reinstalled setcpu and took it down to 710. Is this ok to do?
I ran linpack at both settings and I barely get over 3, on DD2.7 I was getting around 5. I did notice linpack has been updated since I ran it on DD, maybe that's the difference?
Quadrant is steady @ about 400.

Doesnt appear so, but you have 2 easy options. Either nandroid before so you can flash back. Or just flash the ROM again and it will replace the kernel.

Any chance you wanna talk me through building a kernel!?

I'm not a fan of making documentation but if nobody do it, I will, because the knownledge must be shared

It's a nice basic kernel. But just wondering, in the original thread, it's stated that LED is working. But my Rogers Magic still doesn't show red LED during charging. Any explanations?
Thanks, 2.6.29 with compcache and the common g1 kernel modules would be nice =]

Does your kernel allow changing the CPU freq? The previous one you made would not allow the CPU frequency to be set (By apps, etc)
is it permission problem... you cant write the frequencies?!
Just grabbed setcpu and it seems to halt after the intial page so it just freezes up after hiting the "always allow" page from the superuser app just after hiting "android cupcake 1.5" from the intial page of the app it self... what im trying to say that i dont think its a permission problem...
So I just unpack boot-gbo.img and put the kernel in any rom?
/sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
i cant find anything beyond cpu0.

Since this is active:
Code:
CONFIG_MSM_CPU_FREQ_SCREEN=y
CONFIG_MSM_CPU_FREQ_SCREEN_OFF=245760
CONFIG_MSM_CPU_FREQ_SCREEN_ON=528000
Manual cpu scaling cannot be done.
Seems that many people doesn't like this behavior. I am currently reviewing the config to made some performance improvement and will release 2.6.27-gbo-3 during this day.
Small poll so:
CONFIG_MSM_CPU_FREQ_SCREEN or CONFIG_MSM_CPU_FREQ ?

Well, I definitely like to set my CPU and this is pretty common in the stock kernels and other 32B kernels, so I would stick with this. Of course, this is -your- kernel, so you can do it exactly how you want to. :3
It's not "mine" . It's your kernel and my build
Better, it's a community kernel
I'll revert back to stock configuration for this part .

Noma kernel for Huawei U8150
I'm introducing my custom kernel for Huawei U8150 IDEOS phones. In Kenyan Swahili noma usually means "tight," as in: "That music is tight!" It can be used in other ways too, but I like this connotation the best.
GoalsMy aim is to learn about Linux kernel internals, practice software development using git, and to share with the community. In addition to that, I want to explore and test tweaks which lead to increased/optimized performance on this bargain phone (it's very popular in Kenya). Some of the areas of improvement I have in mind are:
CPU scheduling (UI responsiveness, reducing lag)
CPU frequency scaling governors (smartass? ondemandX? interactiveX?)
I/O scheduling and filesystems (flash disk performance, throughput, latency, maybe simpleio scheduler?)
Security (network, local)
Newer drivers (mainstream, community kernel sources)
Newer GCC compilers (CodeSourcery, Linaro)
Easy rooting
Integrate ClockWorkMod Recovery
Integrate busybox
Explore different compression algorithms (LZO, gzip, LZF, etc) for zImage...
Compcache (zram) (info, announcement)
SLOB memory allocator for better memory allocation? (info)
Current features
Code:
- multi-touch gestures (on devices with [url=http://mjanja.co.ke/2011/08/does-your-huawei-u8150-support-multi-touch-gestures/]supported hardware[/url])
- over/under clocking of CPU frequencies
- Tiny RCU ([url=https://lwn.net/Articles/323929/]info[/url])
- BFQ I/O scheduler ([url=http://algo.ing.unimo.it/people/paolo/disk_sched/]info[/url])
- simpleio scheduler ([url=https://github.com/erasmux/hero-2.6.29-flykernel/wiki/Smartass]info[/url])

Source code
I respect the GPL (the license covering the Linux kernel), so all the up-to-date source code for this kernel is available on github. My kernel is, in turn, based on the publicly-avaiable Froyo kernel sources from Huawei. You're free to fork, modify, and re-release the code as your own, but you must provide the source code for your resulting work. Doing so ensures you honor the terms of the license, but you're also giving back to the community. Basically, don't be a ****.
Credits
I've written zero lines of C code for this kernel. My work is merely to search for interesting modifications to the Linux kernel and add them to a git repository. The real work has been put in by the following people:
Linus Torvalds and all the other Linux kernel hackers around the world

v47 (20110823)
Changes in 20110823v47 (from the git commit log):
Add new, lookup3-based jhash. See: http://burtleburtle.net/bob/hash/doobs.html
pids: fix a race in pid generation that causes pids to be reused immediately
lib/decompress_bunzip2.c: fix checkstack warning
kbuild: drop unifdef-y support
net sched: fix some kernel memory leaks
net/ipv4: Eliminate kstrdup memory leak
Add noma_defconfig. `ARCH=arm make noma_defconfig` to use.
Mostly security and memory leak fixes. The new jhash implementation is based on lookup3.c, a newer, more-efficient implementation (more info here). It's mainly used in the kernel's ipv4 and ipv6 stacks, so don't expect revolutionary performance increases, but it's backwards compatible with the old implementation, so it couldn't hurt to include it.
Default IO scheduler is now deadline (the same as stock Huawei) until I can do some performance tests of other schedulers on this device. Note: I've included BFQ, Anticipatory, CFQ, and noop as well, so you can use those if you like!
Download: noma_20110823v47_boot.img
v49 (20110824)
Changes in 20110824v49 (from the git commit log):
Default to ZLO compression of kernel and ramdisk. LZO has roughly the same (but worse) compression, but is much faster to decompress.
Add LZO compression support for initramfs and old-style initrd
Add support for LZO-compressed kernels on x86
Add support for LZO-compressed kernels for ARM
Add support for LZO-compressed kernels
LZO compression is not as efficient but should be faster than the default compression (gzip), which should improve boot time. See: http://free-electrons.com/blog/lzo-kernel-compression/.

Why are you working on Froyo and not on Gigerbread?
Why I'm still working on Froyo
unknhawk said:
Why are you working on Froyo and not on Gigerbread?
Click to expand...
Click to collapse
As this is basically a research project (for both me and the community), the primary reason I'm still "working" on Froyo is that most U8150s are still running Froyo. It's an incredibly popular phone in Kenya (maybe 250,000 - 500,000 units sold?), but I have a hunch very few of them are running non-stock ROMs. Sure, CyanogenMod 7 has a fairly-active U8150 port in progress, but it's not widely used yet.
Like I said, this is primarily a research project, so I'm experimenting for my own curiosity. A part of that is to help people get into Linux kernel, Android, and open-source software development. I want to help set an example of openness, collaboration, documentation, etc.
Also, a lot of the mods I'm making can just as well apply to Gingerbread when we finally get there.
Custom kernel booting on U8150 CM7

Fun times... I just got a custom kernel to boot on CM7. It's nowhere near as usable as tilal's kernel, but it is a good exercise. More info here on my blog.
I suppose that whenever I get bored enough with Froyo I could always hop over to CM7. AOSP is where my heart is anyways.
v56 (20110827)
Changes (from the git commit history):
Add su, Superuser.apk, and busybox. This kernel/boot.img will now actively root Huawei stock ROMs.
Remove pre-zipped ramdisks as they are now generated on the fly from the compile scripts.
Correct the name of the compressed ramdisk (mkbootfs technically creates a cpio archive, which I then zip).
Make sure `make clean` doesn't delete our pre-compiled wireless module.
Add mkbootfs for creating ramdisks, and update compile.sh to create ramdisks on the fly instead of using a pre-zipped one.
Add ramdisk from U8150 V100R001C18B842
The build system is now a little more flexible and generates ramdisks on the fly. This should make it more powerful and complete. I've also included su, Superuser.apk, and busybox to enable a very cool new feature: rooting! If you haven't forked or cloned my kernel repository yet, what are you waiting for?
Regarding "rooting," forget what you've heard (it's probably wrong). Here's what it actually means:
Copying the su binary to /system/bin/su
Copying the Superuser.apk application to Superuser.apk
Period. What this means is that Android applications can call on the su binary whenever they want to do perform system administration actions (ie, not normal user actions), such as removing system applications with Titanium Backup. The Superuser.apk application is simply a frontend for su; whenever an application tries to execute su, a Superuser dialog pops up asking you to allow or deny the request. This notion, known as "privilege separation," is a common one in all operating systems.

v83 (20110903)
Changes (from the git commit history):
sched: export nr_running symbol for use by smartassV2 CPU governor.
config: sync with latest config
sched_fair: Restore less extereme latency values (latency of 6ms)
sched: enable HRTICK
sched_fair: Enable HRTICK
cpufreq: add smartassV2 governor
Switch busybox, older version (1.18.4) but slimmer, more appropriate for our needs (from https://faramir.eriador.org/r/).
Minimum frequency to 122MHz at boot, as well as smartassV2 governor.
Optimized ARM RWSEM algorithm
Cleanup after installation of su stuff. We're on a ramdisk after all, we need to conserve memory.
Change location of root stuff so it isn't in the $PATH
Add Simple I/O Scheduler
Add V(R) i/o scheduler
Update to latest Linaro GCC 4.6 compiler.
Two major changes are the addition of the simpleio IO scheduler and the smartassV2 CPU governor. The simpleio scheduler is based on/around the noop and deadline schedulers, designed specifically with non-rotating media in mind (flash disks, hello!). The smartassv2 CPU governor controls how your CPU switches between frequencies (from 122MHz at idle to 672MHz when in use). I haven't done any benchmarks, but these should improve responsiveness and battery life (in theory at least!).
Other than that, the latest Linaro GCC 4.6 compiler, some small optimizations to ARM-specific functions, and ramdisk/boot cleanups. If you're curious about smartassV2 there's more info here, on erasmux's github page here.

cm7 nightly bugged one ?????? i dnt like it iz there iz n e fixed cm7 for ideos ????
btw your kernel doesnt works with cm7 and can u please make a kernel for samsung galaxy gio with smartass v2 ??
Aorth, I tried flashing you kernal, and unfortunately there is one error when flashing with the latest CM7.1. After the flash, the phone will be stuck at the boot screen. I was wondering if you can get this fixed, that'll be great
This kernel is meant for stock ROMs

Yeah, this kernel was really meant for Froyo stock ROMs. It won't work on CyanogenMod builds because the ramdisk's init scripts are not compatible.
My U8160 kernel repo has a kernel which works on CM7... but you'll have to compile it yourself
nice kernel ........... working fine on ideos u8150-B .... I flash it with stock rom ................. battry becomes efficient ...
Good Job!
Hello aorth,
I'm now using the LEANdroidMOD 5 based on your kernel and I have to say the name NOMA suits it to a tee. It's my default ROM now when I'm not testing your or tilal6991's builds. Thanks and you have yourself a happy holiday season!
hello,
will there be any update of your noma kernel? this is my fav because all roms out there eat my battery like mad, so i just use your kernel and i'm happy with it
greetings
oh man please update, this is one nice kernel!
CM7 u8150 april 5th
IS this already built in to your CM7 last updated april 5th rom or is that a diffrent kernel? which one is better? would it be hard to install it on that rom? whats the advantages over the built in cm7 rom? Thanks sounds awsome anything to make that baby faster is great. Good work
SU Binary Outdated notification
flasehd v83 on the stock 2.2.1 kenya 1 mutli touch rom all went good but whenever i restart the phone su binary shows the notifications bout su binary being outdated which i updated , i did it multiplie times but it comes up everytime the phone is rebooted , other than that su binary working ok ,
dont know how to fix it , other than that the phone is working so responsive , enjoying it
when i flashed the kernel , the phone was already rooted

BCK - Bam Custom Kernel for i9003 / Galaxy SL
This Kernel is based on the Chinese GB source, released by Samsung on the 18th of November. Last changes to the source were made by Samsung on November 15th. If you still have questions after reading this post, look at the FAQs (including a list of requested features and known issues).
Kernel features:
No SOD
Bugfixes:
~ Sync bug fixed. Notifications for new mails and messages should arrive within one minute under all circumstances
~ Bluetooth problems fixed. Your phone now should play nice with bluetooth hosts, i.e. your car audio system
~ Micro stutters nearly completely gone thanks to lowered processor transition latency. It's smooooooooth
~ Home button double presses exterminated
Governors:
~ smartassV2 governor by erasmux (default)
~ interactive governor by Mike Chan
IO scheduler:
~ SIO IO scheduler by Miguel Boton (default)
~ BFQ IO scheduler by Paolo Valente and Fabio Checconi
~ deadline IO scheduler
Extended features:
~ ro.secure=0 (root acces through adb shell - to root the 'clean flavour' of BCK, please follow the instructions)
~ EXT4 support (to convert your file system, use amit.bagaria's ext4 add-on .apk) (Only in CF-Root .tar)
~ Support for init.d scripts (to use scripts, please follow the instructions) (Only in CF-Root .tar)
~ BLN support (to use BLN, please follow the instructions)
~ TUN support for VPN networks built-in (no module needed)
~ Increased SD-card read ahead of 768 kb for improved read speed
~ Available with universal CF-root ramdisk based on amit.bagaria's version, improved by loSconosciuto (Only in CF-Root .tar)
~ Available with universal CWM ramdisk (rooted) based on universal CF-root, but 'tweakless' (Only in CWM .tar)
Overclocking and Voltage:
~ Evolved sysfs interface for variable overclock or underclock (all operating points [OPPs] can be adjusted seperately)
~ Fifth OPP (1.2 GHz) available, device booting up at stock speed (1 GHz)
~ Total frequency control. The device will never run at higher speeds than defined by you, not even on WiFi.
~ sysfs interface for voltages (read only at the moment)
~ Slight undervolt (3%) on all OPPs
Flashing , settings and compatibility:
If you want to use BCK, please flash it on a clean stock ROM. If you want to go back to stock, repartition and reflash the full firmware with ODIN. This kernel will not work on CM or MIUI.
The CF-root and CWM versions (PDA_BCK_CF-root_universal_***.tar / PDA_BCK_CWM_universal_***.tar) can be flashed on any recent Gingerbread firmware. These versions are pre-rooted, which means they include Superuser.
The non-CF-root "clean" version (PDA_BCK_XXKPQ_***.tar / PDA_BCK_XXLE4_***.tar) will only work on XXKPQ / XXLE4. Do not flash this version on anything other ROM than the one indicated in the file name. This will break your WiFi. It's especially risky to flash the clean version of BCK after flashing any CF-root kernel before. Don't do it. This version does not include Superuser, but it is prepared to be rooted. Follow the instructions to do this.
After a kernel update, please wait for the device to boot up and reboot once. There is generally no need for cache cleaning or a full reset. To change the governor and IO scheduler, I use NoFrills CPU Control from the market. It's free and reliable.
I recommend to use the clean XXKPQ version. If you want / need to have root, try the CWM version. If you want the 'full package' with FuGu-Mod and more, use the CF-root. I recommend that you do not apply any further tweaks and use a stock ROM.
>>> Warning: Overclocking may damage your device. <<<
Overclocking instructions:
For overclocking, you will need a shell on your phone, or adb access. I use Android Terminal Emulator. Overclocking is currently limited to certain frequencies (see below) and all operationg points will be set with the stock voltage of the corresponding stock frequency. The frequencies you set have to be within the following ranges:
Code:
OPP1: 100 - 500 MHz, stock 300 MHz
OPP2: 501 - 700 MHz, stock 600 MHz
OPP3: 701 - 900 MHz, stock 800 MHz
OPP4: 901 - 1100 MHz, stock 1000 MHz
OPP5: 1101 - 1500 MHz, stock 1200 MHz, not used by default
Remember that your phone uses all operating points depending on the current load. Anything more than 10% higher than the highest stock frequency is likely to be unstable, but you are free to try it. To change the clocks, open Terminal Emulator (or type 'adb shell') and hack in
Code:
su
echo "1100" > /sys/power/overclock_opp4
as an example. The others are opp5, opp3, opp2 and opp1. That's it.
Settings will be lost at reboot, unless you add them to your init.d scripts. I do not recommend this, as this may cause boot loops if the settings are to high! Be advised that NoFrills CPU Control, SetCPU, or whatever app you use that may adjust clock settings interfers with this. You may wanna update their settings after this. I do not recommend using them to set anything at boot if you overclock any OPP, because they might save the wrong frequencies and crash or do worse.
Changelog:
beta 1:
Added cpufreq governors
beta 2:
Changed smartassV2 settings to fit i9003
Added EXT4 support
Smaller zImage due to .config changes
beta 3 (not released):
Experimented with overclocking (not working, yet)
beta 4:
Finetuned smartassV2 settings
Made smartassV2 governor default
Reverted: Smaller zImage due to .config changes
Switched to linaro 4.6.2 toolchain (also used for ICS)
Activated new, aggressive compiler optimizations (-O3)
Added deadline IO scheduler
Added BFQ IO scheduler (10% higher performance than CFQ in Antutu Database IO Benchmark. This does not mean, that the maximum read or write speed increase! It just means that the throughput under heavy load is higher.)
Made BFQ IO scheduler default
Updated all modules
beta 5:
Variable overclock. Loosely based on the modifications of the Nook Color sources by dalingrin and of course with help from amit.bagaria and DooMLoRD.
beta 6:
Variable overclock for all operating points
beta 7:
Switched to universal CF-Root by amit.bagaria (BCK now should run on every recent GB ROM)
Added correct version information in settings menu, credits to DooMLoRD
Fixed cpufreq stats to correctly reflect frequency changes
Increased SD-card read ahead to 768 KBytes. This results in higher SD-card read speeds.
Major simplifications in overclocking code. Works more robust, now.
Added sysfs interface to show voltages. See /sys/power/overclock_vdd_oppX
Changed all voltages to the mainline Linux kernel defaults. This results in a slight 3% undervolt for each OPP, which saves about 5% power and should have no impact on stability whatsoever. Below you will find an overview of the exact voltages.
Code:
stock BCK
OPP1: 1.0250 V 1.0000 V
OPP2: 1.2000 V 1.1625 V
OPP3: 1.3300 V 1.3000 V
OPP4: 1.3875 V 1.3500 V
OPP5: not def. 1.3800 V
beta 8:
OPP5 (1.2 GHz) now enabled in _1200 version of kernel. Thanks to knzo for pointing me to the right patch.
Fixed video recording bug when running at 1.2 GHz
Fixed power management issues at 1.2 GHz
Small changes to smartassV2 and interactiveX settings
beta 9:
Added simple IO ('SIO') scheduler
Only one kernel version now, which includes OPP5 (1.2 GHz) but boots up at 1 GHz. Be advised that your device may nevertheless be running at 1.2 GHz for five to ten seconds at boot because of software limitations.
Changes in PM to always respect cpufreq policy limits. From now on, the device will never run at higher speeds than defined by you, not even on WiFi. Based on an omapzoom.org patch.
Changes to OPP switching code. May lead to less 'hickups'. Based on an omapzoom.org patch.
Bugfix for framebuffer code. Based on an omapzoom.org patch.
Reduced IVA / DSP frequency when on OPP5 to be on the safe side.
beta 9fix:
Reverted: Changes to OPP switching code. May lead to less 'hickups'. (Patch caused random freezes using WiFi.)
Reverted: Bugfix for framebuffer code. (Patch showed no noticeable benefits.)
beta 10:
Fix for sync bug applied. If you still have problems, please report.
This version is identical to beta 10rc14. No need to flash again, if you already are on that version.
beta 11:
Updated universal CF-Root by amit.bagaria to version 9 (released 1st of February 2012), but NO touch recovery
Slight increase in OPP5 voltage (1.38 V -> 1.40 V), may prevent some reported reboots on 1.2GHz
Code:
stock BCK
OPP5: not def. 1.4000 V
Changes in overclocking code to play nice with your frequency settings. If you overclock OPP5 but have restricted freqs to 300 - 1000 MHz, it won't automatically activate OPP5 anymore. The same is true for the lowest OPP.
If you overclock OPP4 above 1000 MHz and have restricted freqs to 300 - 1000 MHz, it will update the upper boundary to the new frequency of OPP4 so it doesn't get deactivated.
beta 12:
Fixed bluetooth problem with car audio systems (Based on omapzoom patches [1], [2] and [3]). Might resolve other bluetooth issues, too.
Universal CF-Root: Fixed bootanimation. Thanks to loSconosciuto.
Universal CF-Root: Fixed install procedure. It will check the actual kernel version, now. Thanks to loSconosciuto.
Universal CF-Root: Fixed fix_permissions script to work on our device. Thanks to loSconosciuto.
Switched to user_defconfig, to avoid unnecessary debug lines in dmesg.
beta 13:
Updated sources to GT-I9003_SWA_GB_Opensource_Update1 from the 30th of March. This also enables TUN support by default. You do not need any modules for this - it works "out of the box" with any VPN client.
Universal CF-Root: Backup is not failing anymore when started from CWM. Thanks to loSconosciuto.
Universal CF-Root: Some small improvements to multiple scripts.
Home button double press issue fixed. There should be no more unwanted double selections in CWM and you can now reliably long press the home button to bring up the list of previously used apps. Idea and timer function taken from a patch by Tegrak.
Fixed priority class for CONTENT_PROVIDER not being set, which may have caused apps of this class to be ignored by the autokiller, resulting in less free RAM.
Lowered OMAP processor transition latency to the value recommended by TI. Subjectively, this brought huge improvements in terms of reducing micro stutters.
Lowered CFS scheduler latency and granularity to values very close to mainline kernel defaults. This could reduce lags in some critical situations, but it doesn't do wonders.
Switched to SIO as default IO scheduler.
beta 14:
Universal CF-Root: Replaced CWMManager and TweakManager with zipaligned files. Thanks to loSconosciuto.
Universal CF-Root: The TweakManager is not replaced on install if it didn't change to preserve it's settings. Thanks to loSconosciuto.
Universal CF-Root: Corrected problems because of too little free space in /system when converting to ext4 by permanently moving InfoAlarm.apk from /system/app to /data/app. Thanks to loSconosciuto.
Universal CF-Root: Fixed the non-working WiFi on XXLE4 and prevented future problems. Instead of patching the WiFi modules, they are now replaced. Thanks to loSconosciuto.
Universal CF-Root: Fixed some small mistakes in the CF-root install procedure.
Switched the compression of ramdisk and kernel from gzip to lzma. This makes the files much smaller and allows us to include more 'stuff'.
Changed smartassV2 settings to wake up at lower frequencies. Further, it is not locked at 300 MHz anymore when the screen is off. Tests showed that free scaling is more battery friendly.
Removed InteractiveX and OndemandX governors and added the Interactive governor by Mike Chan (Source: CyanogenMod Crespo kernel). Since free scaling proved to be more battery friendly, the screen off profiles in InteractiveX and OndemandX made them superfluous.
The device will not scale above 1 GHz for some seconds when booting anymore. It's now safe to use BCK even if your device can't handle 1.2 GHz. Based on a patch by dalingrin.
Changes in PM to respect cpufreq policy limits when playing or recording video. The device should respect your wishes under all circumstances, now
Fixed the SmartReflex voltage calibration of the OMAP SoC for OPP5. This could lower power consumption as soon as OPP5 (1.2 GHz) is activated for the first time.
Slight increase in the OPP5 nominal voltage (1.40 V -> 1.42 V) to allow for some adjustment by SmartReflex (now that it's working...), if necessary. The actual voltage when the device is running will not change for most users! Based on patches by dalingrin and Sanjeev Premi.
Code:
stock BCK
OPP5: not def. 1.4200 V
beta 14 fix:
Universal CF-Root: Fixed the non-ending row of force closes after flashing the Universal flavour of BCK. The clean XXKPQ version did not show these problems and didn't need a 'fix'.
beta 15:
Universal CF-Root: Modified some permissions to bring it closer to the stock ramdisk
Universal CWM: Created a CWM ramdisk based on CF-root, without most tweaks. You now have three BCK flavours to choose from
Updated to newest UPDATE2 sources by Samsung
Sync bug fix reworked to use new Samsung method from UPDATE2. This may lead to slightly lower standby battery consumption.
Fixed accidental front camera mirroring
Editing smartassV2 settings with busybox 1.20.x and newer no longer leads to reboots. Thanks to loSconosciuto for pointing me to the patch.
Fixed complete crash of WiFi driver when activating WiFi by adapting smartassv2 thresholds
Reverted to the original Google Android toolchain using gcc 4.4.3
Because of the toolchain-switch, the compiler optimizations are now back to -O2 instead of -O3

it doesnt have oc ! it has special cpu governors which are efficient and fast
tough luck for me mate....
i compile a vanilla kernel which is ~200 kb larger than stock zImage and it doesnt even boot!
also,even i want to update to 2.6.35.14,,,,,,,,,,,,,,how u did it without source?
also(2)lz open an acc. on github!
@sakindia123: Take a look here, update your sources to the new version, and get the new toolchain they use (see readme in the sources).
i followed that link before......
ok i will try with new source
what will happen if we use this ? are there any good feautures ?
it has special cpu governors which are efficient and fast
Now just wait for some days guys. Doomlord, bam, sakindia will show u real power of our device.
This is great! Just one little question, you said this is for a chinese firmware, but you mention KPQ, so it can be put in XXKPQ or not? Anyway sorry for my noob question

It is based on the Chinese source - this includes kernel and android system source. But the kernel is universal (not language specific), and I applied all necessary settings for XXKPQ. Therefore you can flash it on KPQ.
what does a kernel do??
it is the main driving force of a phone that i know.
does it make our phone fast??
how to flash it as i would like to give it a try right away!!
can i roll back to stock kernel after this??
sorry for thr noob question as im new to all this.
---------- Post added at 08:45 PM ---------- Previous post was at 08:40 PM ----------
also do we need to have CWM recovery for this????
or we can do it with the stock recovery menu??
i was just doing some testing and the kernel is stuck at "SAMSUNG" bootanimation after a FRESH FLASH...
any idea?
used on XXKPQ FW
I flash your kernel. From last 5hours no SOD ISSUE. I'm using smartass v2 let's see how will battery I will get from it.

Fresh flash of what PDA? Yours, mine, GitHub?
@manrock111: smartassv2 gives me slightly higher battery usage than stock. I want to tweak it, but have problems with my sources at the moment.

As many of you probably already know, I had another 'Fusion' kernel for the S4 HTC One S. However, because I incorporated mdeejay's patches, the kernel did not play nice with the CPU and whatnot. I nuked my repo, imported the T-Mobile US kernel sources, and re-built the kernel from scratch. I wanted to start a new thread so people would not mix up this and the old kernel.

Downloads
Do NOT flash versions 3.0 and higher in recovery!! They are 7zips!!
I purposely made it a 7zip archive so people don't flash it. Instead, extract the appropriate zip from the package and then flash like before. You get options of whether you want overclock or stock clock. The zip will flash the correct files and modules according to your choice and then clean out conflicting init.d scripts for the best possible compatibility.
All Downloads are HERE
How to Install
For hboot 1.09 and below:
Just flash the zip in TWRP recovery. It will automatically flash the boot.img for you.
For hboot 1.13 and up:
you have two options
Option #1
Use TWRP's HTC Dumlock feature. It is a pretty neat workaround that allows you to flash boot.imgs in recovery even on a higher hboot.
Look here for instructions from TeamWin. If you are not comfortable with this method, then follow option #2 to manually flash in fastboot.
Option #2
In addition to flashing the zip, you will have to extract the boot.img from the package and flash it manually with fastboot. Blame HTC for the half-assed 'unlock bootloader' offering they give us. Hopefully we will get S-OFF soon...
Code:
adb reboot bootloader
fastboot flash boot boot.img
fastboot erase cache
fastboot reboot
Look here for a guide.

For Developers
How to build this kernel from source:
This is assuming you already have your Linux environment setup and installed the required packages for compiling a kernel.
1. Clone my initramfs and kernel sources.
Code:
git clone git://github.com/klin1344/kernel_ville_US.git
git clone git://github.com/klin1344/initramfs_ville_4.0.3.git
2. Compress the ramdisk into a gzipped archive. First navigate to the initramfs_ville_4.0.3 directory, then:
Code:
find . | cpio -o -H newc | gzip > ../ramdisk.gz
3. Grab the toolchain from DoomLord's handy repo:
Code:
git clone git://github.com/DooMLoRD/android_prebuilt_toolchains.git toolchains
4. I have created an easy build script. Modify the top four lines to be applicable to your setup. Make sure CROSS_COMPILE is set to the directory of the toolchain we just downloaded earlier (there are two; not the Linaro one). And change INITRAMFS_DIR to the directory of the ramdisk.gz you created earlier.
5. Build. First navigate to the kernel_ville_US directory.
Code:
./build.sh ville_defconfig
for the stock option or
Code:
./build.sh ville_oc_defconfig
if you want the overclocked option.
The script will detect the number of cores of your CPU and automatically make with the optimal -j#.
6. If all goes well you should end up with a boot.img in the kernel_ville_US directory.

FAQ
Frequently asked questions. Please read all of this first, and then if it doesn't answer your question, feel free to ask in the thread. I just don't want to have to keep answering Is this kernel SENSE based? or How do I jailbreak my HTC One S??? type of questions. Lol. :silly: Thank you.

What ROMs is this kernel compatible with?
As stated in the OP, this kernel is compatible with all S4 devices running a 4.0.3 Sense-based ROM. It is NOT compatible with the new 2.21 RUU, which is Android 4.0.4 based. We will have to wait until HTC releases the new kernel source because the differences are not only in the initramfs.
What is the best governor for me to use?
It really depends on what you're looking for. If you want performance, go with Lionheart or Ondemand. If you want battery life, go with Conservative. And if you are looking for a balance between battery life and performance, then use either SmartassV2, Interactive, or LagFree. These are just my opinions. Look here for a great reference of all the CPU governors. Test them out and decide which works best for you.
Which I/O scheduler is the best?
I personally use SIO, but you can test and decide which is the best for you. Read here to find the pros and cons of each one.
How do I overclock?
The kernel should default at 192Mhz 1.5Ghz CPU clocks. To overclock, use SetCPU, No-Frills CPU, System Tuner Lite/Pro, or any similar CPU control app. Some apps don't allow the settings to stick properly. I recommend using No-Frills or System Tuner.
How do I undervolt?
Right now, the only app that works for voltage control is System Tuner. Both the Lite and Pro versions allow you to change the voltages. Do not use SetCPU as it doesn't work.
Here is the voltage table I am currently using:
Code:
1890mhz: 1250 mV
1809mhz: 1225 mV
1728mhz: 1200 mV
1674mhz: 1175 mV
1512mhz: 1150 mV
1458mhz: 1137 mV
1404mhz: 1125 mV
1350mhz: 1125 mV
1296mhz: 1100 mV
1242mhz: 1100 mV
1188mhz: 1075 mV
1134mhz: 1075 mV
1080mhz: 1025 mV
1026mhz: 1000 mV
972mhz: 1000 mV
918mhz: 975 mV
864mhz: 975 mV
810mhz: 950 mV
756mhz: 950 mV
702mhz: 900 mV
648mhz: 900 mV
594mhz: 875 mV
540mhz: 850 mV
486mhz: 800 mV
384mhz: 725 mV
192mhz: 650 mV
Please just take these as a grain of salt; not all chips are created equal! Some devices can become an ass when it comes to undervolting, while others can starve the CPU to death and still run fine. Experiment little by little until you find your perfect voltages.
What is zRam and how does it work?
Originally Posted by faux123

ZRAM is an updated version formally known as CompCache and RAMZSwap. It was originally designed for 2.6.38.xx kernels, I have backported to our 2.6.35.xx kernel. ZRAM allows real-time compression of memory objects in RAM thus reducing memory pressure for the Linux kernel and can keep more apps in memory longer (more apps in RAM == better performance, less fetching from slower MMC or SDCard). Compression, however, is not Free. Some CPU cycles are required to do the compress/decompression, so there's a slight penalty for it. The original CompCache / RAMZSwap required a user space binary to control its behavior which adds additional penalty to performance, but the new version ZRAM eliminated the need for a separate dedicated daemon, thus reducing the overhead and increased performance from the old CompCache by 20%. Therefore, with the newer implementation of ZRAM interface, the performance penalty is almost negligible.

WiFi doesn't work???
Flash the alternative modules package in the OP. It is for EU based ROMs as well as MIUI Sense-based. You only need to flash it once, unless you change or update your ROM.
Nice..Will do testing...
Hopefully it give the best battery life than stock
Thank you sir!

Thanks. But unfortunately the reason I did not make it a zip is because that some of us who are on hboot 1.13 or higher can't flash boot.img's in TWRP recovery at all. The same goes for radios. I stupidly ran the 1.78 RUU, which update my hboot from 1.09 to 1.13. :crying:

How do you like the new radio? I seem to be getting a lot better service and a more stable WiFi connection.
Liking the kernel so far
Sent from my HTC VLE_U using xda premium
Bug I found -
-While install apps it take awhile for it to install. (1mins or 2min). I just phone the sit until it finish install
-After reboot ...the kernel take awhile for it kick in. For example..If you have email it will take awhile to prompt on notication bar .
Is it possible you can post zips for download in the OP? Thanks. Will try tomorrow.

Maybe try wiping data / factory reset? To be honest those sound more like rom issues rather than kernel related issues.
I cannot reproduce it.

+1 but the thing is a bit complicated because we need current modules because of better wifi signal.
I guess we'll just have to wait for the new kernel source from 2.21 base
just flashed it with axiom v1.8.0
everything seems to be working fine.. it's fast smooth stable
nice stuff, Klin
Trying this now in hopes my frequency changes stick after a reboot unlike stock :/

Is it normal for CPU settings to not stick after a reboot?
I set 1.3ghz/384mhz max/min for both cores. I reboot and it defaults back to 1.5/192
Basically same issue with stock kernel.

Setting don't stick after reboot. I'm using setcpu
Also, When I applied this kernel..my screen flick across the screen while exit app (es explorer)
This is a kernel, build from the recently released saga-ics-crc-3.0.16-62a67df source.
Compatible with all ICS (Android 4) + Sense (3.6, 4A or 4) based ROMs
OFFICIAL MIUIv4 and Stock rooted ICS users can enjoy init.d scripts support with this kernelEnjoy!BACK2BASICS EDITION
FEATURES
Interactive Aroma Installer
Completely Stock code, with only 2 additions by me:
Configurable sweep2wake.
Ported bcmdhd wireless driver from the HTC One V latest source code for better reception and no wakelocks. Still breaks WiFi tethering in ROMs based on Sense 3.6. Tethering works fine in Sense 4
Completely Stock ramdisk. The only changes are:
Unsecured boot.img (adb remount and USB debugging)
Busybox run-parts (init.d scripts) support
Some extra lines, required for the proper operation of the new WiFi driver
No OC, UV, optimizations or any other changes.
Compiled with the recommended by HTC toolchain 4.4.3
ISSUES
For all with BLUETOOTH issues: use 4EXT Recovery
due to incompatibility with sweep2wake the native Sense screenshot function has to be disabled (on some ROMs Power+Volume Down is working- 10x to rzr09 for pointing it out). You will need to change the value of ro.htc.framework.screencapture = , located in /system/build.prop from true to falsemanually, using any root file explorer. To make it functional again (if you decide to disable s2w) just change back from false to true
NEW USERS: before flashing install/update BusyBox in /system/xbin (with some of the apps available in the Google Play - the one by Stericsson+Smart Install worked fine for me) and check for the existence of the busybox binary and run-parts symlink in the /system/xbin folder on your device. If there is no such files install/reinstall BusyBox until you have it.
OPTIONAL: If you do not have an /system/etc/init.d folder AND you want to use additional modules you should create it manually BEFORE flashing the kernel:adb remount
adb shell
mkdir /system/etc/init.d
chmod 775 /system/etc/init.d

fastboot erase boot
fastboot flash boot XXX_boot.imgIMPORTANT (HTCdev users): if you are using 4EXT Recovery Control for flashing make sure to select the "Stay in recovery after flashing" option!
Boot images are:
Sense4_boot.img - for all Sense4 based ROMs (Fallout, ProjectX, Cooldroid, Sabsa Prime, Desire XS, ViperSaga, others)
Custom_Sense36_boot.img - for ICE_DS, Stock ICS by masteross, or other custom Sense 3.6 ROM without lib partition
Stock_Sense36_boot.img - for Ice Cream Saga or clean RUU/PG88IMG (that keeps S-OFF and Recovery) install (rooted)
MIUIv4_boot.img - for any version of official MIUIv4
NOTES:
There is no boot.img for Virtuous Infinity since it cannot operate smooth with the Stock CPU settings
If sweep2wake takes screenshot upon screen off in this version you have to modify your build.prop manually (see above)
PATCHED KERNEL 3.0.89
Due to controversial feedback on Tweaked kernel starting from version 5.0 I have decided to take a different approach.
Patched kernel unifies the concept of both Tweaked3 and B2B kernels.
So what does this mean?
The HTC source is taken as a base and is synced completely with the upstream (the official Android kernel 3.0) where applicable. Since it is patched only up to 3.0.72 the rest of the patches are taken directly from the Linux kernel upstream.
All is done from scratch and revising every single commit (it took me 4 days to complete this only). The result is absolutely clean merge (not as in Tweaked where I took the patches from other developers without actually knowing have they screw up something in the progress). During the patching I have discovered some misses or copy-paste from 3.4 upstream (which I consider for another generation devices and probably the changes from there are not completely suitable for our device). I have cleaned and synced with the 3.0 upstream all not-updated files that I discovered during the patching.
FEATURESThe features of the kernel are the basic ones from Tweaked, but staying as close as possible to the Stock configuration (B2B concept):
Interactive Aroma Installer
Compiled with GCC 4.4.3 toolchain
Patched to Linux Kernel version 3.0.89
Synced with Android kernel 3.0 upstream
Overclockable to 1.5 GHz
Added VDD sysfs interface for userspace UV control
Stock Frequencies and Voltages
Default governor: INTERACTIVE @ 254 - 1024 MHz
Interactive governor updated from android 3.4 upstream
Default scheduler: DEADLINE
Configurable Sweep2Wake
Fixed WiFi tethering on Sense 4 based ROMs
Updated WiFi drvier from HTC One V source
Built-in CIFS support
Built-in TUN support
Built-in NTFS + NLS_UTF8 support
Optional WiFi calling
Two way call recording - both WAV and AMR
Enabled USB OTG HOST (big thanks to astro757 and engelmarkus)
Enabled SWAP support
ISSUES
If your WiFi does not work upon install check this solution /10x to toxic-hero/
Sometimes the sweep2wake does not work instantly after deep sleep period. Just swipe once more to unlock the device or press the search button.
due to incompatibility with sweep2wake the native Sense screenshot function has to be disabled (on some ROMs Power+Volume Down is working- 10x to rzr09 for pointing it out).

SetCPU
Voltage Control {settings not stick after reboot on Virtuous Infinity}
No-frills CPU Control {settings not stick after reboot on Virtuous Infinity}
Daemon Controller app + andrev_oc script
note1: there is virtuous_oc on Virtuous Infinity already, so you can use only the Daemon Controller app
note2: oc daemons are not supporting scheduler changing
undervolting can be done with a command from Terminal Emulator or adb shell:echo -X > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levelswhere X is the desired value (-25, -50, -75, -100, -125 or whatever you like). Unfortunately has to be repeated after every reboot since putting it in an init.d script is risky
Originally posted by engelmarkusHi,
I played around with the experimental branch of your kernel once more and today it works perfectly.
Keyboards, mice and USB storage devices work without any messing with the terminal. For almost-auto-mounting I used this app here: https://play.google.com/store/apps/d....shajul.usbotg
So I think you can very well enable this in your next kernel version so others can try this out, too.

Compiled with the latest stable Linaro GCC 4.7.3-2012.11 toolchain
Patched to Linux Kernel version 3.0.56
Upstream update of interactive governor change speed routine
Enabled TINY_PREEMPT_RCU - should give small-memory-footprint on uniprocessor systems (where all processing tasks share a single CPU)
23 Nov 2012: Tweaked3 10.0 (X):
Patched to Linux Kernel version 3.0.52
Removed all third party governors
Removed BFQ, VR and CFQ schedulers
Tweaked SIO for better performance on Android
All modules built-in, except the one for WiFi Calling (kineto-gan.ko - optional)
No more init.d scripts, except for sweep2wake
During installation a /system/etc/init.d folder will be created, with the right permissions on ROMs that do not have such
09 Nov 2012: Tweaked3 9.0:
Compiled with the latest Linaro Toolchain 4.7.3-2012.10
Patched to Linux Kernel version 3.0.51 (10x to oliverclaude)
Ondemand and Interactive governors synced to upstream (10x to Andromadus)
Scheduler improvements (10x to faux123)
16 Oct 2012: Tweaked3 8.6:
Patched to Linux Kernel version 3.0.46
Updated BFQ code to v5 (10x to Andromadus repo)
2WCR now makes recording in WAV format (10x to Andromadus repo)
BCMDHD wireless driver is updated to the latest HTC One V source - there are some changes related to the Country Codes, so please anyone that has such issues to try it without WiFi FIx app and report
Initialization of the wireless modules moved to ramdisk, no need of init.d script to run them anymore, so new users can skip that part and go straight to flashing!
10 Oct 2012: Tweaked3 8.5:
Patched to Linux Kernel 3.0.45
Added ck1 patchset by Ziggy (thx to Coolexe) - aims towards better performance
Removed ZRAM - it seems that the compression was the reason for the battery drain
Removed the script for changing the screencapture line in build prop from Aroma, hopefully this will solve the installation issues. You will have to change it manually if needed
01 Oct 2012: Tweaked3 8.0:
Aroma installer - one file for all. No need to do any preparations anymore (like changes of the updater-script, etc) The installer will gather the important information about your ROM and hboot and the flashing process will be done accordingly.
HTCDEV users: there are instructions in the first post which boot.img to flash. Important: if you are using 4EXT Recovery Control for flashing make sure to select the "Stay in recovery after flashing" option!
All governors are tuned up according to the CPU frequencies (should have done it long time ago, sorry for the delay). OndemandX (proved unstable) and Userspace (doubt that anyone even uses it) governors removed
CIFS, TUN, KINETO_GAN, NTFS+NLS_UTF8 and ZRAM moved to modules for optional install (the installer will give you a menu for selection, where the purpose of each module is explained)
Updated LZO compression/decompression method for ZRAM (it sould be at least twice faster now)
TREE_RCU and SLAB memory allocator set as default (as it was in the Stock kernel).
21 Sep 2012: Tweaked3 7.1:
Patched to Linux kernel version 3.0.43

Added VDD sysfs interface (10x to lowveld) for userspace UV control (comes with Stock Voltages by default)
Added BrazilianWax, InteractiveX and OndemandX governors
All modules except bcmdhd.ko are built-in in the kernel
Finally found the reason of the battery drain when the Screen is ON and hopefully fixed it. Now the battery life should be rock solid
Flashable zips should be fixed for good. They now will wipe dalvik-cache and cache during flash, no need to do it manually. Version 5.0 zips are backwards compatible (this means you can flash version 5 over version 7.1 without additional actions (deleting or moving files)
05 Sep 2012: Tweaked3 6.0:
Added bcmdhd WiFi driver and fix WiFi Tethering on Sense 4 ROMs (10x to m0narx)
Flashable zips are back!

27 Aug 2012: Tweaked3 4.7:
Expanded frequency table - to give the CPU more steps until the highest frequency
Slight undervolting to save some battery life
Fixed backlight staying on when pressing only home button when s2w with backlights enabled (10x to scan6 for the heads up)
Default clock frequency is 1024 MHz for everyone that requested it
Enabled init.d support in the MIUIv4 version (now you can use the 50-sweep2wake script too)

On Fallout the backlight works as it should.
In a room without direct sunlight - off
On screen off - off
Outdoor or in a dark place - on
Try in different conditions, maybe there is too much light where you are
I wish it was usable for non Sense ROMs
Nik 4.1, Atuntu - 3527
No prob with S2W. Auto brightenss is off.
Thx Stefan.

I am not a big fan of benchmarking. But tried just out of curiosity.

It's perfect! I haven't seen so cool and fast rom as fallout with this kernel yet!
Is it not harmful for Desire S to overclock to 1.5 GHz ?
Shouldnt make any harm going to 1.5.
Now the kernel source, is https://github.com/showp1984/bricked-shooteru-ics-sense what you releasing? if no you need to release the exact kernel source you using, laws
I dont want any saga dev to have issues
Edit:
More then that, some devices comes with stock 1.5 with same processor but remember, the more you put, the less battery
Hi, is there a way to revert it to stock? Thanks.

Good point
Yes the changes for sweep2wake are the same, made by showp1984, unmodified by me
And yes, this is the stock OC, I have just enabled it for the time being.
I am pretty sure that soon there will be much more tweaked and polished kernels made by the experienced devs, but since most of them are taking summer holidays I compiled this one for playing with Sense 4 until they come back to development

Yes you can always flash the original boot.img of the ROM that you are using via fastboot. Then copy the bcm4329.ko and kineto_gan.ko of your original ROM to /system/lib/modules with any root file explorer. To restore the stock screenshot feature change the value ro.htc.framework.screencapture from false to true in your build.prop
