I reported a couple of kernel tweaks I came across on the web the other day but there has been no response yet so I thought I'd start a new thread to catch peoples attention!
The tweaks are for non-BFS kernels only (e.g. Flykernel 10a) and alter a couple of the parameters within the scheduler. I dont know enough about linux kernels to give more details but I was hoping someone who did know more would explain what the parameters do.
After applying the tweaks my phone is the smoothest I have ever felt it be and subsequently I have returned to 528MHz. Even now it feels smoother than I have had it on any other ROM when OC'ing > 600MHz. This means my battery life has seriously increased too. My phone has been running 26 hrs with email and weather updates with still 66% left.
I am currently using elelinux 1.8 and flykernel 10a @ 528MHz and I honeslty dont feel the need to flash any ROM updates anymore (yet!). The tweaks are:
EDIT: Due to some confusion I would like to make it clear in the following commands DO NOT type the '#' or '$' symbols. These are just to indicate what the terminal shows.
from ./adb shell or terminal emulator on phone
$ su
# mount -o remount,rw /system
# echo 'kernel.sched_latency_ns = 600000' >> /etc/sysctl.conf
# echo 'kernel.sched_min_granularity_ns = 400000' >> /etc/sysctl.conf
# echo 'kernel.sched_features = 24188' >> /etc/sysctl.conf
# mount -o remount,ro /system
# sysctl -p
(the following should print after typing previous command)
kernel.sched_latency_ns = 600000
kernel.sched_min_granularity_ns = 400000
kernel.sched_features = 24188
# exit
$ exit
Try them and see if it makes your phone smoother. Im sure they will. and if they dont then just delete the sysctl.conf file and you should return to normal on next boot.
EDIT2: Ok so it has become apparent that the tweaks to dont speed up ALL ROMS as the title suggests. I apologise for this over big-uppery. I think the main reason for this is that some devs have already incorporated similar tweaks (cronos?). Also erasmux has been playing around with the tweaks and he has suggested that not all the tweaks have a significant effect on performance. Of course you are all welcome to play around too and find whats suits you best. As for me, im going to leave the tweaks in because for the first time since buying my hero i am pleased with its performance and I dont see the point in removing a couple of lines from a file if it makes no difference!
Also, it is worth noting that there may be some down side to these tweaks as pointed out by Decad3nce on page 5 (post #44) in that apps requiring constant cpu time such as gps may become jumpy. I havent noticed any ill-effects yet but then I havent been on any long drives with sat-nav either so I dont know. (if you have already got yourself seriously lost or missed some meeting I apologise).
If after reading all this you still want the tweaks either follow the instructions above or flash the updated kernel elelinux was kind enough to compile (page 3) or there is another link on page 4/5 i think
Now if C0mpu13rFr34k would hurry up and finish that theme my hero may well be perfect!
Oh wow Thanks i will try this now also does this affact the bechmark scores in anyway ill report if does
A-MA-ZING, wow it's so smoother ! it work so fine !
haha how you get that done so fast im still typing
Edit: Grrrrrr..!!!!!!! Terminal crashed when typing this owell try again
I've not benchmarked it since applying tweaks but I don't think this will change benchmarks. It just improves the 'interactivity' which is all I want to do. Benchmarks are just numbers!

As far as I know it will work. Though I think you will need root to write a file to the /system directory.
Sent from my HTC Hero using XDA App
Anyone tried adding this to one of the init.d scripts and seeing if it helps speed?
You will need root to use most of these, as they are setting kernel params, and IIRC that requires root.
Doesn't the .config file cause the settings to be applied at startup?

Yes, if you compiled a kernel using these tweaks in .config, then they would be applied at startup by default. This would just let people test it out and see if they wanted to compile using these settings for good, as I imagine they will.

Are you definitely on a non-BFS kernel? I think this is an issue if you have a BFS kernel.

hmm im not too sure to be honest. If you followed the instructions as I listed them I dont think you should have the problem. It seems as though the commands werent written to the sysctl.conf file. Again im not really very good at programming so I cant give you much more help. sorry

If you have the Android SDK then go to the tools folder in a command prompt (or terminal in linux) and run:
adb remount (./adb remount)
adb shell
then the following: (if you go straight through the terminal emulator in your phone dont run the above 2 commands)
$ su
# mount -o remount,rw /system
# echo 'kernel.sched_latency_ns = 600000' >> /etc/sysctl.conf
# echo 'kernel.sched_min_granularity_ns = 400000' >> /etc/sysctl.conf
# echo 'kernel.sched_features = 24188' >> /etc/sysctl.conf
# mount -o remount,ro /system
# sysctl -p
(if your above commands worked it should print:
kernel.sched_latency_ns = 600000
kernel.sched_min_granularity_ns = 400000
kernel.sched_features = 24188)
# exit
$ exit
and you should be done.
if i have a recovery image but not SU apk, can i still do it?
can someone please help me add init.d support to my rom. the rom is BML. I have searched and im not finding anything.Im trying to learn so if anyone would like to volunteer to answer a **** load of questions i got them.

what do i add that to?
Im just trying to do something soo damn simple so i can be done with his rom. I dont even know if init.d script will do it or not. I need RTSP and HTTPPD proxy to be 0.0.0.0 and the ports to be 0. Im irritating the crap out of myself trying to figure this out. maybe its just a lost cause, i have been trying to figure this out for i dont know how long with no luck. im ready to just slam this damn phone and give up.
If i use a kernel that supports init.d do i need anything else?
my new approach would be a script. i can use the following command in adb to set the rtsp and httppd.
setprop net.cdma.rtsp.proxy.addr 0.0.0.0
setprop net.cdma.rtsp.proxy.port 0
setprop net.cdma.httppd.proxy.addr 0.0.0.0
setprop net.cdma.httppd.proxy.port 0
now i just need to write a script and place in init.d. can anyone point me in the direction to getting this done.

You would add that in init.rc. You could also change the build.prop to change those values. Or you could change them in init.rc. I'm not at my computer right now to tell you the lines that need to he added to either of those to change the value.

i was trying to add it to the build.prop but i dont think i was putting the right info in.i just added the following to the build.prop with no change.

just asking,is there a way to set the oom value of certain apps using terminal emulator or any other alternative?im using autokiller memory optimizer apps and it kill the messaging apps due to its high value of oom.is there a way to lower it since this app dont hv that function(it does hv but temporarily).already did some research and found a similiar thread in xda but the respondents suggested using other apps to lower the oom(e.g system tuner pro,supercharger,automemomry manager).im curious if lowering the oom can be achieve with just using terminal emulator.thank you in advance

yes, you have to search for the right PID after every boot.
If you know the exact package name (e.g., com.yadda.yadda.yadda), you can easily pgrep for it. Example script:
Code:
#!/system/bin/sh
targproc=com.yadda.yadda.yadda
targoom=-8
targpid="$(pgrep $targproc)" || exit 1
for p in $targpid; do
echo $targoom > /proc/$p/oom_adj
done

the thing you need to set there is the targproc and the targoom value. com.yada.yada is only example. the problem we have here is we don't know the pid because it's changing like variable in algebra so the command
Code:
targproc=com.yadda.yadda.yadda
targoom=-8
targpid="$(pgrep $targproc)" || exit 1
is needed to find the pid of the process you want. the real code is
Code:
for p in $targpid; do
echo $targoom > /proc/$p/oom_adj
done

First off, I did not come up with this idea but I adapted it from smokin1337 and his thread: [MOD] EZ InitD - init.d the EZ way !!
How to make it work...
Take file in the attached zip and use your favorite root explorer and paste it in /system/etc/ overwriting the file that is there.
Set permissions of the file to be rwx, rx, rx
Create an init.d folder inside of /system/etc and set permisions to rwx, rx, rx
Add init.d scripts and make sure they are also set to rwx, rx, rx.
Reboot and enjoy your init.d scripts!
All credits to smokin1337 for the mod, I just added the line to our postboot.sh.
I tested it and it works as it should :good:
Enjoy!
-Scott
EDIT: Changed the permissions of the scripts to 755 from 777 to guard against possible malware. Info courtesy of jcase.
Just a note, I use ES File Explorer to do this but any root level explorer should work. I just use ES because I am familiar with it.
Some init.d scripts can rely upon the use of BusyBox so install that from the market.
Sorry for the stupid question but what does this actually do.
What can I get out of it if I install it?

Good question... If you have to ask it then this is not something for you. Haha, Just kidding... But seriously..
Basically init.d scripts are scripts that run when the phone boots up. You can make them do various things like setting system level tweaks, cleaning and purgin databases, and on and on and on...
In the ROMS I build I use an init.d script that remounts the file system more efficiently (in theory anyways) but there are other uses for init.d scripts.
A real popular one is called "V6 Supercharger" Its a collection of scripts that are designed to really tweak out the operating system for the supreme performance (once again, debatable).
There are other things that could be done... If your familiar with old school computing and you know autoexec.bat this is basically that for Android.

Yeah, this mod is not your ordinary mod. Most people will never use this type of mod.... Or they do use it in the custom ROM they use and never even know about what it does.
Try using 755 instead of 777, otherwise you are opening yourself up to potential problems.

I'm really confused as to what you want to do, but if I understand correctly, U want to make it temporary so if users reboots the script doesn't stick but if the user wants it to stick it will create a init.d rite??
And ye i would also ask have u any experience in scripting because this is pretty/verry easy
So basically for it to be temporary you just want to run the script, if u want it to stick after reboot you must place it in init.d folder or for lupus Kernels you could also place it in boot.d, dependinfg on wether u want it to run on BOOT or INIT.

Yes thanks, someone understands,, lol, Yes, thing is i dident Learn, i just read alot of scripts and tested out a TONNE of different things and values i wanted to use in my script which is HERE
And its universal accros all devices so some might not have boot.d but init.d most of them will have, And thats what i want

I checked your script a while ago, and it needs a lot of improvements, you should add user privilege check to the script, and add a line to mount system with read/write permission. And also you should make the script a bit more aggressive and give the user some choices to pick. Unfortunately I don't have much time to do it myself, but I'll try to.
Anyway to make the script create another script in init.d with text in it it's really simple, here's an example:
echo #put your first command here# > system/etc/init.d/99LagNullifier
echo #put your second command here# >> system/etc/init.d/99LagNullifier
">" overwrites any old text in the file
">>" adds to the existing file

Yes thanks, someone understands,, lol, Yes, thing is i dident Learn, i just read alot of scripts and tested out a TONNE of different things and values i wanted to use in my script which is HERE
And its universal accros all devices so some might not have boot.d but init.d most of them will have, And thats what i want
I want to have 2 options and have one to make init.d files and one for temp (Temporary method is working fine now, )

Oh OK and not being smart but do u know wat each line of your script does. Because I have seen many users creating scripts and although the desired effect works there are parts which are not needed or the creator does not have a clue what they do. They just cram in awhole load of things which look or sound good. IM NOT SAYING THIS IS YOU.
I'm not at a PC rite now so can't look at your script. But seen as u don't want to make it a flashable zip, I would suggest something that maybe u could run via script manager or terminal like lupus menu. With a couple if options like set on every boot. Or run until reboot and say a check to make sure other init.D's do not conflict with yours. Just some suggestions.
Lol @Themike_10452 the below will probably confuse the hell out of him
inspire yourself with this code
clear ##clear the screen
echo ""
##check for root privilege
id=`id`; id=`echo ${id#*=}`; id=`echo ${id%%\(*}`; id=`echo ${id%% *}`
if [ "$id" = "0" ] || [ "$id" = "root" ]; then
echo "Root permission: Yes"
else
echo "Root permission: No"
echo ""
echo Please run the script with SU permission
sleep 3
exit 69
fi
if [ ! "`which busybox`" ]; then ##check for busybox
echo "Busybox found: No!"
sleep 3
exit 70
else
echo "Busybox found: Yes"
fi
echo ""
busybox mount -o remount,rw /system ## mounts system as r/w

Good but I would still however look up some bash so u know exactly what's going on and how to fix it if u run into problems.
Ok I looked through your script quickly there... as mike said there is still alot of work to do. this is not ment as destructive criticism but constructive, to help you make it better, which i'm sure is what you want.
It can be cleaned up quite a bit. It looks like you took alot of other peoples scripts/tweaks and put them together with a lot of sleeps, which certainly will not be good... unless u run them in the background. Because device wont boot for a long time with them all, I think there is 3/4mins where script pauses. It will be fine in boot.d as it wont affect boot time but in init.d seems like a NO NO. also thigs like
Code:
/system/xbin/echo 1 > /proc/sys/vm/oom_kill_allocating_task
can simply be
Code:
echo 1 > /proc/sys/vm/oom_kill_allocating_task
or even better, I think its a good idea to create a variable for busybox say BB. I noticed on LuPuS script at the start certain commands would not work unless I had busybox before each command. I run my kernels busybox from /sbin, So would be
Code:
BB=/sbin/busybox
-- this way
Code:
$BB echo 1 > /proc/sys/vm/oom_kill_allocating_task
As I also mentioned u should place a check so your script will make sure any scripts already in init.d will not conflict. And if they do give the user option to overwrite or keep their current script or back it up.
edit - Crap u said u wanted it to be universal. So maybe better to check for busybox.
Code:
if [ -e /sbin/busybox ]; then
BB=/sbin/busybox
elif [ -e /system/xbin/busybox ]; then
BB=/system/xbin/busybox
elif [ -e /system/bin/busybox ]; then
BB=/system/bin/busybox
else
echo "No busybox found!"
fi
Thanks alot, for all the help guys! I'll get on working and just to clarify I took the base commands from Lenarox, Juwe11 & many others, tested them & modified alot to find the best combo and I added some of my Own Tweaks!,
Also with the whole sleeps thing I already know that it's not Good In init.d and so o was making it to
Just inject all commands
Also in the script their were alot of sleeps because this way it gives each tweak to settle in

Ok I tried testing this:
(Thanks mike)
Code:
case $input in
y|Y) echo "Would You Like to Reboot Now?"
echo "Your phone will now reboot"
sleep 2
echo ""
echo "========== POOF! ========="
sleep 1
reboot ;;
*) echo "If You Dident Reboot Then..."
echo "Reboot Manually!"
sleep 2
exit ;;
esac
And it dosent work in smanager... Need some help with it,
