Hello, guys!
I guess most of you know about this "magic patch" that significantly boosts Linux speed. It's going to be merged in the 2.6.38 branch and it's shipping with Ubuntu Natty too. But this kernel patch can be applied to a previous kernel as well, just rebuilding it with this 224 magical lines of code.
What I wanted to know is if it's possibile to rebuild our kernels with this patch, if it is already, or if it's possibile but won't have significant boosts on Android devices.
You may read more about this on Phoronix. On the 2nd page there are video demos for lazy ones!
This has been discussed here twice &found not to help because we dont use harddisk.

was it "proven" or "theorized" ?

Thank you, but can you please link the thread with this discussion? I can't seem to find it. Also, this patch regards CPU, not hard disks.
this patch will be officially introduced in the 2.6.38 kernel..
also, this kernel will have about 50% more speed increase, due to the 200 lines patch and another issue resolved after it .. in general the upcoming kernel will be blazingly fast !!
there is a script that tries to do the same as the patch for earlier kernels. which I use on my Ubuntu laptop, and yes major performance increase !!
I tried to apply it to my previous phone (HTC Hero), but didn't work. I also asked Cyanogen on his twitter, but didn't care to give me an answer..
finally I gave up, and decided to wait for the next Android version that will have the 2.6.38 in the future..

I'm using that script too on Maverick! I don't think there should be a significant increase in responsiveness if you apply it on high-end systems, but our SGS might benefit from it (as my old dual core system).
You say it didn't work on your Hero, but were there any errors in dmesg or you didn't find any significant change in speed?

dmesg should no difference. the script just showed a lot of errors.
I tried the "non-Ubuntu" version as described in Webupd8, but still similar errors.
I guess Android place the kernel differently from Linux desktops.
I might be mistaken, but SO kernel uses its. And haven't really noticed any difference with or without it.

please don't spread incorrect facts:
* the "automated per tty task groups" (or autogroup) patch - by using cgroups (in CFS - the cpu scheduler) and thus isolating several taks from each other, giving them dedicated slices of cpu power - allows the system to be more responsive under load if there is a kind of cpu hog (task producing much load)
* the speed increase is due to Nick Piggin's VFS changes and Andrea Arcangeli & Mel Gorman's Transparent Hugepages (THP) support (and of course lots of other changes)

that's correct: - "sched patch : automated per tty task groups (system more smooth and responsive) (v3(since 4_3) and v4(since 4_4))"
so you tried SO kernel with the patch applied and once reverted ?
but - yeah, I got you: I'm myself running a heavy patched 2.6.37 kernel with transparent hugepages, CFS autogroup, etc. enabled - and it certainly can play off its advantage most noticably during heavy system load

So, please, correct my noobiness, isn't Android using TTY shells? If it's not than I understand why this patch can't be applied, but if it is, rebuilding a kernel with just 200 lines more is no big deal and we all could benefit from it. It's not very common for Android to be under heavy load but hey, it's going to be default in 2.6.38, so why not?
There is a better patch :

But I don't know if android uses shells.

Yes, that's exactly the script I was talking about a few posts ago. On my system running 2.6.35, I did not rebuild the kernel with the "patch of wonders" but applied this script. But as you may have read, it acts in userspace which is slightly different in Android (as far as I know it's not using the same environment variables and I don't know about any ~/.bashrc equivalents, but again correct me if I'm wrong), that's why a kernel-oriented patch would be more suitable.
* well, actually newer revisions of that patch don't make use of ttys but of the task session
so basically it seems to create separate groups for each task (or program for simplicity's sake)
(source)
I'm also not sure if current Android kernel revisions use CFS at all ("Android versus Linux?")
laststufo has the autogroup patch included in his SO Kernel but I don't know how to measure its effect ... (whether it makes any difference)
* other options to improve interactivity would be to use Lennart Poettering's bash-approach (the script), like MaXo64 already posted: link
since Android uses Bourne Shell (sh) instead of BASH the script might need to be rewritten
* if it's stable enough on the SGS - yet another option would be to use Con Kolivas BFS

well, you could rewrite that script that it is run as a init-script (afaik in /system/init.d/ )
besides that:
there are stripped down (smaller) versions of bash 4.1* that are known to work on CM6 and the HTC Hero
so it should be a possibility to use that script on stock roms, too
if you can install busybox & root it, there also should be the possibility to install bash

It seems you're very well informed, so thanks for the infos you're posting!
I'm not a coder, though, so I hope a kernel developer could pick this up and go for BFS. You said laststufo already implemented this patch in his kernel, so that's really good! We should just find a way of testing its effectiveness.

Uhm, so it seems BFS isn't stable on our hardware, pretty bad.
I shared before a patched libsqlite.so for froyo and now I bring you CM7's one.
Advantages: Faster I/O operations (applications will open/close faster; quadrant I/O will be higher; ...)
Download: http://dl.dropbox.com/u/13427114/patched-libsql-CM7-p970.zip
Instructions: Just copy to microSD card and flash on CWM like you usually do. No wipes needed.
I may not have a Black anymore but I still want to see my favorite community spoiled with goodies!
P.S. Needs to be reflashed after each nightly/version.
thanks !!!
And this is the reason why Nova will always have a special place in our hearts xD

Thanks a lot!
However, could it be used to our android 2.2 STOCK ROM??
big thanks for this great job
Is this file device specific to p970? Can I possibly use it on my CM7 Nook Color which uses the OMAP3610 processor?
thank you knzo, you have really done a lot! And i deeply appreciate your work.
This really work? This make things faster?
Yeah, no problem on me. That is increase i/o performance, better than v20n stock rom..

Hi guys,
According to one polish android fan he went into troubles using this patch (data integrity issue - phone lagging, maildroid issues), so be careful using this and pay attention to ownhere's statement:
ownhere said:
WARN:The following steps only for developers. The following changes may cause instability or even cause the phone can not be used.
Android phones as the underlying database using sqlite3. sqlite3 writes efficiency is very low, because the sync feature turned on by default, and fsync() must be performed after each insertion, the resulting system efficiency is low, and the disk life is reduced.
I try to disable sync feature by default in exchange for greater IO performance and reduce disk consumption. While doing so may result in data integrity problems, but I still like to use it because most of the sqlite insert action can be completed within a few seconds, not too much to consider issues such as sudden power-down.
After modified, the time of insert 2000 records to sqlite3 db, from 1m11s reduce to 2s.
Attachment is my sqlite3 patch, it is for CM or AOSP.
For SenseROM, I can not simply replace libsqlite.so from AOSP, so I do hexedit with it.Do follow modify for SenseROM libsqlite.so:

Upon request from fellow member ascariz on the smartassV2 governor, I've compiled intellidemand module for Arc 4.0.3 stock kernel.
Since the firmware I use is the Arc S one (ICS 4.0.3) - I believe this module will also work for Arc S.
To fully configure / install the module, please check this page for a similar module I did for X10 back in the days - page.
Some things are different, but if you want to hand customize all possible parameters after phone starts up, the path to check is
Code:

OMG. you really do it?! tq mate!
After a day of testing, I'm switching back to smartassV2.
With smartassV2:
a) the time in state shows me about 16-17% at 1Ghz, and the others at 122MHz. Intermediate frequences are rarely used.
b) battery was about 40% at the end of the day with my usage (4 email accounts doing sync at 15 minutes - I'm not using push, but k9 connects) - also half of the day in an area where 3G signal is weak and phone swiches back and forth.
With intellidemand:
a) the time in state is 6% for 1GHz which might look better in comparison with smartassV2.
BUT:
b) the phone is sluggish and you can feel it needs a bit of time (1 second ?) to pick up speed, UI animations are choppy.
c) it does make use of the intermediate frequencies - but battery was about 20% when I got home, identical usage as previous day with smartassV2.
In both cases, screen was always kept at 25%.
Now my conclusion is that:
a) intermediate (but high) frequencies have similar battery usage as maximum frequency.
b) spending more time in an intermediate frequency makes things slower to finish and thus, based on point a) drains battery more.
Also, the code of intellidemand is more complex (.ko size is +20Kb more) as opposed to smartassV2 - and thus I guess it also takes more time (energy) to compute the correct frequency. In itself, a complex algorithm to compute the next state takes its toll.
smartassV2 does perform better with my usage pattern - and I'm curious why this governor is claimed to be advanced I mean algorithmically it surely is, but phone is more sluggish + more battery drain (not significant, but about 20% in my basic, 1 day test).
I will focus my attention on other *ass governors

this is intellidemand and smartassv2 modules that you can load in 2 way.
1) for those who use stock kernel that not support init.d, use script manager to load MODULELOADER script at start up. after flash, browse at system/etc/init.d folder and you will find the script.
2) for those who use kernel with init.d supported (e.g. Cobrato kernel), do nothing. just flash it and you ready to go.

Doesn't work man. :/ The new governors aren't showing up in No Frills CPU..using Cobrato's kernel.
First you must use the stock kernel from Sony's official 4.0.3 release for Arc S (even if having the Arc).
Any other kernel will not work ... (or very slim chances to work).
Second, please check using Module Loader app (but only activate the boot time loading of the module after you are sure the things work).

Hmm...I thought you didnt have to use module loader for the flashable zips ? :/ Because the module loader shows 'Starting modules...' in the middle of any game (Like Temple Run) and it begins to lag horribly, this pisses my friends off. I want to show them how great a phone Arc/S is. :/
Ok, if it has the same version number then it will load the modules ok (as well as having the same binary kernel image).
I think the OS kills Module Loader to regain some memory, then starts it back when memory level gets better (kills it when game / heavy app starts, then as memory becomes available, it starts it back). But Module Loader has a bug and when started also loads the modules
Another solution is to use Script Manager ( http://www.androidsoftware.us/Applications/Script-Manager.html ) to run a script at boot (a small script that just do the insmod).
Hope it helps...

Goal: kickstart 3.x custom kernel development.
Changelog:
Built with Google's 4.6 toolchain (* see notes).
Merged Interactive from mainline and enabled input boost by default as part of Google's Project Butter. Interactive will be the only available governor as it's Jellybean's "official" governor and having more selection only slows down the kenel. Interactive will provide more smoothness, especially with input boost enabled, but it may be slightly more expense on the energy consumption (significantly? maybe).
The I/O scheduler is deadline with the fifo batch reduced to 1. For smartphones the best I/O schedulers are often the simpler ones and that means deadline, simple or noop. However, for these 2 years deadline keeps providing me the best results, at least in single-cores. Noop is also available. And yes, I know about the new BFQv4 and all the tweaks/heuristics for flash devices, it's still crap.
Switched the slab allocator to slub with a decreased max_slab_order (Andrea Righi) in order to reduce overhead.
Glibc versions for memcopy and memmove, improved CRC32 and RWSEM algorithms, Tiny Shmem implementation, etc.
Changed RCU to Tiny Preempt without RCU boost, some config cleanups and debug removal (like frame pointer) and so on.
... more changes can be seen in: https://github.com/knzy/lge-kernel-sniper/commits/android-omap3-3.0
A few notes: BCM4329's PM_FAST is already enabled by LGE. I also didn't merge many mainline updates as like it has already found out this often hurts performance and decreases stability. Furthermore, you may notice that there aren't many modifications to the kernel but this is because most patches out there are bull**** and rely on placebo effect. Even some changes I did will have a doubtful influence in the kernel. Oh, one more thing, it's possible to build it with Linaro 4.7 toolchain (it needs a few fixes in Makefile though) but it's less stable and not that much faster.
Download: There'll be no available flashable zips. Just build the kernel if you want and use Aprold's kernel injector package.
Now, any kernel posted in XDA must be GPL compliant which means sharing the source, the config file and the toolchain used. I will now shortly describe how you can build the kernel in a linux (ubuntu-based) machine (by the way, if you see anyone sharing a kernel without providing source, config or toolchain, tell me and I'll report them):
Code:
git clone git://github.com/knzy/lge-kernel-sniper.git ## default branch is omap3-3.0 already
git clone https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6 ## Add -b master if building on 64-bit
cd lge-kernel-sniper
make ARCH=arm knzo_p970_defconfig
make ARCH=arm CROSS_COMPILE=../arm-eabi-4.6/bin/arm-eabi-
The kernel will be at arch/arm/boot (zImage), use it with Aprold's kernel injector package and voilá.

does anybody download? how is it?
You need to flash gapps too I believe.
EDIT: error in zip could not install, will try again.
not install ...
Hi,
OMG!!!
I just looked into your init.d folder...
You collect lots of scripts to put in your ROM, fine, but put them all together, less good..., just my opinion. Would have had to sort out and look a bit some values, more than half are completely useless.
For the same tweak you have two, three or four times the same values in different scripts or even 2 different values in the same script...
For the same tweak you have x value in a script and y value in another one (and for some tweaks you have 2 different values in the same script!)...
At boot one erase another while a third erase yet the previous (according to the execution order at boot).
Your scripts for RAM "management" is the best example of against productivity, two scripts for zipalign, your scripts for "net speed" are also the same, etc...
30 init.d scripts running, obiously, at boot... it is not a bit much? Check the duplicates (or more) lines and tweaks, removes unnecessary scripts and makes a little cleaning...
It is not because you have 30 different scripts with multiple lines and values that is necessarily great, remove all your scripts (or keep one for the "RAM management" maybe (and still not sure ) and your ROM will runs perfectly.
Sometimes "more is the enemy of the good", here it's a good example... And don't say the user can choose or edit... probably the most (or all) people who flash this don't know the point of this or that script...They will flash the whole zip with all your scripts inside without knowing what they do... It's totally useless. People see "speed" "fast", "smooth", "performance", etc... ok GO GO GO! flashing! + placebo effect...
You'll have the same goal without the whole script , the ROM will runs perfectly without all this... bunch of scripts...
Ask some devs the usefulness of these scripts, you'll be surprised. I've already tested some of your scripts... Most do little or nothing, are not adapted to JB or needs to be reworked when we have 2 Go of RAM (the scripts for RAM "management"), or are not adapted to our phones (look at your "14enable_touchscreen", where do you find the path in our N4 ??? the path /sys/class/touch/switch/set_touchscreen does not exists... you are echoing a value wich does not exist-> totaly useless script), etc...
Just my opinion and some tips...
Keep the good works up !
Waiting for most features

build.prop and init.d hero :good:
You should be ashamed of yourself dude.. I really have no idea why mods are so easy on ppl like you.
I encourage new devs, honestly if you had compiled stock cm I would've congratulated you.. but if you're gonna skip the steps and just BS your way through then we'll shoot your plan full of holes.
Nobody flash this ROM it's junk..

Ok mate, I'm going to say this slow and easy.
Getting a cm10.1 base, removing apps and just collecting all init.d scripts is not the way to make a rom.
Go to guides, and read more until you know what exactly you are doing.
Or else, you'd see thousands of roms here.
Plus, changing the android version in build.prop doesn't make it Android 10.
