Setcpu

Is anyone using setcpu? I bought it back when I had the hero but I'm not sure if it will work now on this phone. I'm rooted using toast's method if that even matters for something like this. thanks in advance!

It's the same CPU as the Nexus and it has settings for the Nexus, so in theory it should work. I had a Nexus before this phone and it worked fine.

I believe, like the Hero, you need a kernel tweak to have true overclocking.

yeah I dont wanna overclock i just want to downclock when the screen is off to save battery. I tried using the nexus one settings but it didnt seem like it was working using on demand. The clock speeds it was showing were kind of goofy. Guess i should wait for the programmer to update it

what?!? what do you mean u dont want to oc... theres always room for more speed!

true that but i have always been nervous about burning up the processor hehe

Overclocking would be nice, but I'd also like to save some battery with the on demand profile. Does anyone have it working?

I posted a patch in a thread in the development forum that would enable full support, plus overclocking, but nobody seems to have noticed it.
I might have to buy an EVO just to compile and test kernels... Or, if anybody wants to help me, shoot me a PM.

I used the unrevoked method to root and picked the N1 for the device in setcpu and it seems to be working great with the on demand setting. I have noticed a nice increase in battery life so far.

Is it linked or built-in?
If it's linked I'd be more than happy to test!

yea i use 1.5.4 pro edition... i make it go to 245mhz while idle/sleep... it works perfectly... and it runs 'ondemand'... if you dont need speed it wont go... i keep it to start at boot, and have ATK to ignore it so it doesnt close... theres no lag btw when it moves back to 998mhz

[KERNEL] EternityPRJ Kernel for HTC Vision (BFS+BFQ / [email protected] MAX) [READY]

Welcome to the Eternity Project Kernel for HTC Vision Thread!
The Eternity Project Kernel for HTC Vision (T-Mobile G2 & HTC Desire Z) is developed for gaining the maximum possible speed mantaining the maximum safety on our devices.
The Brain **** Scheduler improves performance on tasks: it is a desktop orientated scheduler, with extremely low latencies for excellent interactivity by design rather than "calculated", with rigid fairness, nice priority distribution and extreme scalability within normal load levels!
This kernel also features Budget Fair Queueing: it is a Proportional Share, or equivalently Fair Queueing, disk scheduler that allows each process/thread to be assigned a fraction of the disk bandwidth.
Features:
- Brain **** Scheduler (BFS)
- Budget Fair Queueing (BFQ)
- Clock table modified:
-- Min: 184MHz @1000mV
-- Max: 1.7GHz @1400mV
- Other features are coming.....
Installing:
- Decompress it if it's compressed (.zip/.tar/.tar.gz/.tar.bz2)
- Connect your device through USB FastBoot
- Use FastBoot for flashing it (found in Android SDK): fastboot flash zimage kernelfilename
- Enjoy!
Image downloads:
v0.2: MegaUpload
Kernel GIT Repository: http://gitorious.org/eternity-prj/eternityvision
NOTE: HTC Vision is UNLOCKED! You can compile and try it right now!
Thanks to the guys over #G2ROOT @Freenode for the S-OFF!
Stay TuneD!

Anything new with this kernel?
It's like a ghost town in here, how does this differ from the current kerrnels?

Wifi not working for me,...
tried using bcm4329.ko from http://forum.xda-developers.com/showthread.php?t=840074 but still no Wifi.

Same, also benchmark scores were a lot lower across the board. Phone didn't feel as snappy either, would like to test further but no wifi is a deal breaker
Sent from my T-Mobile G2 using XDA App

This kernel will be updated in a few days.
NEW:
-- BFS --> CFS
-- Tree will be updated to the latest HTC's sourcecode.
-- Frequency tables will be updated.
Stay Tuned.

Perhaps underclock that speed slightly, some phones can't handle it and will slow down/freeze when clocked too high

Hopefully that will change after xmas

Yeah, from my experience, anything below 245 MHz is unusable. 184 might be too slow and causing hiccups. 1700 MHz has been blazing fast for me and my G2. Just thought I'd share my experience with my Desire Z brethren, lol

Please could someone be kind enough to post quadrant scores

Is it safe to use this on stock Sense ROM?

i just see this thread, looks like nothing new here, keep your good work, gonna waiting for something in your kernel

This sounds really awesome. Was this updated? I don't see a changelog or different version numbers so I was just wondering.

Easiest way to tell, look at the last edit date on the initial post. November 16th. =(

I was really interesteed in this kernel @ first and then I did some research on the BFS. From what I've read Google had actually looked into incorporating that scheduler into their source but could find no benefit in blind studies.
I really wish I could remember where I read the article.

[Kernel] [Sprint] [1.4/1.2 OC] Bauxite Kernel - 2/12/11 -V3.3

Extremely Alpha Code
Hey everyone...
I've developed what I think is the first 1.2ghz overclock for the Galaxy tab Sprint ONLY.
WARNING: THIS KERNEL MAY NOT WORK ON YOUR DEVICE, MIGHT DESTROY YOUR DEVICE, MIGHT PUNCH YOUR CHILDREN, I AM NOT RESPONSIBLE FOR ANY DAMAGE CAUSED BY THIS KERNEL, USE AT YOUR OWN RISK
Whew... now that the warning is out of the way I present a 1.4/1.2 overclock based off of the details here:
http://forum.xda-developers.com/showthread.php?t=943669
Quadrant Score: 1129
Linpack Score: 19.29
You will want to unpack the zImage and push it over with Heimdall, while in download mode (hold down power + vol-down until you get the download mode screen).
FOR OTHER DEVELOPERS
------------------------------------------
As I stated before, if you follow the link above and modify the exact same lines you can add this to you kernels as well.. however the file names are different, the files you want to modify are..
arch/arm/plat-samsung/max8998_consumer.c
arch/arm/plat-samsung/s5pc11x-dvfs.c
arch/arm/mach-s5pv210/clock.c
The last one took me forever to grep and find...
This is just the first of many versions, I will look into other CPU frequencies and voltages, lets see how far we can push this baby.
Donate!

V3.3 --- EXT4 ONLY Kernel... only use this if you are on ext4
V3.1 --- Fixed Ext4(?) NOPE
V3.0 --- Based on EA24 Source - untested with older software. Adds EXT4 (broken)
V2.0 --- 1.4/1.2 GHZ OC, reverted previous changes, NO EXT4 (yet..) ONLY FOR SPRINT, USB FIXED - based on koxudaxi's patch
You'll want to use the voltage control app here:
http://forum.xda-developers.com/showthread.php?t=943669
V1.2 --- 1.2 ghz OC, 1.35 Overvolt (for stability), ext2/3/4/rfs
V1.1 --- Added 1ghz back in as a choice, reset your setcpu to select it.
V1.0 --- Added 1.2ghz overclock (replaced 1.0ghz default, will fix later)

would you be willing to do one for us gsm users if we provide kernals for you

Testing now but awesome work!! Works like a charm! I would take it it would run stable about the same speeds as the other Hummingbird processors at normal voltage ( 1200 ) and lower voltages at 1440 just fine but who knows
This is with this Kernel and OCLF.
(LinPack 17.5)
(Quad Score 2369)
(SmartBench 1469 3344)

Damn you, sprint users. . At least there is hope for pushing the Tab now, cheers

How about just setting #define USE_1DOT2GHZ 1 in s5pc11x-dvfs.c and in linux/arch/arm/mach-s5pv210/cpu-freq.c?
That should switch everything to 1.2GHz tables that Samsung nicely prepared for us?
it seems to work for me just fine.

how to update?

Are you sure it works without altering clock.c? Until I changed that file my device was reporting 1.2ghz but it was still super slow.
EDIT: nvm, you're right. Changing that would change clock.c as well. I don't plan on using the default tables, but it's a good place to start if you want to stick to default values. I know this thing can do more than 1.2ghz.

Anyone could do it easily, but I"ll see what I can do. I've gotten ahold of roto's initrd, I just need to grab the source from Samsung. I don't get home until very late in the evening so I can't promise that someone won't beat me to it!

Please, someone beat him to it.

I've never flashed a kernel before, but it worked without a hitch. Thanks!

This sounds awesome, I'm curious if it makes a big difference in performance and how it affects battery life, those of you that use it please post your experiences! Thanks! I know using custom kernels on my N1 makes a huge difference though so I'm hoping this does too...

Looking forward to seeing how much difference this makes, my n900 i clock to 1.2ghz from the default 600 clock (downclocked cortex A7 @ 600mhz default). so pretty sure the tab should do 1.4 or so faultlessly?
Looking forward to GSM revisions, hopefully Roto may even include this in his roms later (well i'm wishing ^^).
Nice to see someone brave enough to start the ball rolling

Any word on if this will work for vzw?
I just bought a Galaxy tab and I've never built an Android Kernel before but I spent yesterday tearing through the how-to from the CM guys. I'm familiar with C pretty well, so I was glad to see that I'd be building C and not some Java I'd be totally illiterate to. I'm hoping stepping up to these crazy ARM cores from my usual embedded work with AVR's and 32mhz ARMs shouldn't have too terrible a learning curve.
Anyone who's done kernel building for android before: Is it pretty much a straight forward build process? For some of the embedded work I've done with RTOS systems I've spent days digging through memory maps, linker files and assembly code to trouble shoot issues... Just curious if those will be useful skills for android?

I actually used the Verizon kernel configuration, since there is no sprint one. I think it should work on Verizon.. make a kernel backup first!
The only difference could be in the initrd but I have no way of knowing until someone tries it.

On Vibrant, Trinity was DoW.
But there are more SGS flavors than stars in the sky, so that might not change anything

Based on feedback received over the past week+ I would probably prefer the 384MHz inferno.
Sent from my RW Sensation.

If you are benchmarking be sure to force gpu rendering and edit file in /system/lib/egl and delete first line totally, so only the second line stays (thanks bigxie )..
Here are another 2 build.prop tricks your rom might or might not use:
ro.kernel.android.checkjni=0
windowsmgr.max_events_per_sec=240
Paste anywhere in build.prop. it won't change benchmarks, but real feel.
Hope this helps

Morfic, I have thorough enjoyed testing your kernels and im glad it has progressed this far! You don't even have a Galaxy Nexus yet! Hopefully once people get a taste. Of your kernels, more people will donate!
Even though you just started developing for the gnex, your kernel is already amazing! Thanks for all the hard work!

Now I'm jealous that I did not get to try them out

Morfic I gotta say helping you test these was a pleasure. This thing at 512 MHz gpu is super smooth and quick. My battery life over the past day has also been stellar. Can't wait for you to get the phone so you can run the fruits of your labor lol. Amazing work man.

[Custom Kernel]Which Performance Settings Do You Use? [JellyX-Kernel]

Hey guys, just wanted to have a little Thread, where people can Post their experiences with different Performance Settings.
Please also Post on which Rom/which Kernel version you are
I think i should start...
Processorsettings:

Max Frequency: 1000mHz
Min Frequency: 300mHz
I/O Scheduler: NOOP

KSM: on
Battery is ok, not really having the Feeling, anything changed.
Performance is ok, but i think i gonna need to try some other settings.
Feel free to post your settings and experiences
Really guys our defy is no(!) S3 or oneX please dont expect it to be as fast as one.
Also: dont be angry at people, if their settings dont work out on your phone, there are a lot of little differences between our phones. So find your personal best and post it, so others can try it

I think you are not aware of the fact that lately members have started expecting too much on this forum from defy after custom kernels came in action. after every build is released by Quarx people just keeping whining "the phone is bit slow" "perfomance is not that good" " its not fsster". So obv someone needs to give them a reality check. The aggressive end is nothing but truth. Shouldnt be hard to digest.

But what does this have to do with my thread?
Was it just like: All dudes who come here, be aware, we only have a middle class phone.
Or was it like: Dear Esok, you are to blame, cause you are thinking that way.
I like the Defy and i hope, that one day it will be possible for me to experience my defy, with cm10/cm10.1 which has an ui as fast as cm7.
But i am willing to wait for it. My experiences aren't that high, until we have 3.0 Kernel, I'm pretty sure, quarx is able to do that, but if he wont, its ok, hes a person too.
So I think, you meant other guys, with your aggressive ending and there really is nothing to argue about, isn't it?

I think you aren't aware about this simple question, its under what settings do you think your defy runs well. If people think that means we expect it to run faster then a super computer then I do not think this a place where everything has/ can be(en) spelt out. Just because one guy said it somewhere on some thread doesn't mean it applies here as well.
@esok- put up a statuary sign saying this will not make your phone a super computer, but it helps you figure out the optimum settings for your need.
@ngu I tried using your settings on jb28 with kernel 29/11 jellyx but phone was just too cranky! Tried finding one for myself but got tired after a few attempts and re flashed the quarx kernel
