[Kernel] Lightspeed 0.1.1 - Faster than fast enough.

FOR 1.5 ROMS ONLY.
Thanks to teknologist, maxisma, toastcfh, and all those who contributed to cracking the CPU open for overclocking.
Looking at the CDMA forums, it seems they were a step ahead of us with their kernel speedups. With help from their work, and particularly, from toastcfh, I've been able to patch and compile a kernel based on teknologist 1.9 with added features and speed.
Added features and changes so far:
- BFS, brainfuck scheduler. Basically, helps the CPU respond faster.
- Overclock. Up to 768MHz is enabled, but defaults to a safer 595MHz. It should be compatible with SetCPU. Be sure to use the custom setting.
- Deadline I/O scheduler. It should make file read and write operations a tad faster. We'll see if it really does.
Git repo: http://github.com/Soaa-/-lightspeed/tree/master/kernel-hero/
It runs at 595MHz! How do I make it faster?
Download and install SetCPU. It's available for free on xda-developers, but you can support the author by buying a copy on the market. Launch SetCPU and pick the custom option.
My phone doesn't wake sometimes! Or, it wakes and the crashes!
Use SetCPU and set the CPU governor to 'performance'. Try lowering the clock speed if the problem persists.
Can I flash this on recovery?
The first overclocked kernel was available only as sources, and binaries had to be flashed manually. Lightspeed comes as a standard update.zip package to be flashed through recovery though.
Does Wi-fi work?
Yes.
Does compcache/ramzswap work?
No idea. I don't use it.
Is it noticeably faster?
Yes. This isn't a 5% increase in speed, where the difference is only seen through benchmarks. Most phones can handle 691MHz, which is a 30% increase in speed. The lucky ones who can clock up to 768MHz get a 45% increase. The net result is a more responsive phone.
Does the CPU frequency scale to usage?
It can, if you keep the ondemand CPU governor. However, there have been reports of instability using the ondemand governor, so the performance governor is recommended instead.
Do you accept donations?
Not yet, as my work so far has just been putting other people's work together. My priority now is to make our phones better, not to make money.
0.1.1
Integrated setcpu.txt into update.zip.
0.1
Initial release

Hi,
Looks great! Does it work in 2.1 roms?
Greetz

I want to know also
Does it work on 2.1 oms ??

Sorry, the kernel is made for 1.5 ROMs only. The only decent kernel for 2.1 is still the same leaked one from a while back, I think.

ok, gonna try it now on a 1.5 rom, with setcpu.
let you know if speed is there

i use a stock rom, and have the recovery menu so can i put the zip on the sd card and then flash it ?

I am also interested in a guide on how to install/flash this properly.

Just like knudsen81 said. Everything working perfect with CPU running on 595Mhz.

From what I see, it should be flashed like all other kernels so just like ROM or radio.
Does this kernel scales overclocking depending on CPU load? For ex. lowers when idle or screen turned off.

when setcpu launches, it doesnt have the "auto detect" option
when i click on custom, it shows 528 max and no more..
what am i doing wrong here?
flashed the update.zip like a normal rom/radio btw.

Good job! looking forward for testing. What's actually missing from making overclocking work with 2.1?

I used Overclock widget to see the speed of the CPU. I only wanted to confirm if the 595Mhz was true
Also Linpack score went from 2.3 to 2.6.

Create a file named setcpu.txt at the SD card (so it will be /sdcard/setcpu.txt)
and enter the following into that file:
Code:
96000,115200,134400,153600,172800,192000,211200,230400,249600,268800,288000,307200,326400,345600,364800,384000,403200,422400,441600,460800,480000,499200,518400,537600,556800,576000,595200,614400,633600,652800,672000,691200,710400,729600,748800,768000
This will allow setting frequencies from 96 to 768 MHz via SetCPU

Thanx 4 the great work.
2 questions.
first, what does "Git repository" means and when will u release it?
second, can i flash it over Modaco 3.2 through recovery mode?
sorry 4 my bad english.

thanks for the help, lets try this out and see what happens =P

worked like a charm, thanks a lot =)

Does the camera work?

Camera, WiFi should work because it's an (old) 1.5 Kernel.

Other overclocked kernel works faster than this one (and with this one i've freezed ..) ..
With the other linpack gives me 3.2 3.3
with this 2.6 at max ..
:/

Have you set the cpu to 768? because the other kernal runs at 710 by default where as this runs at 595 but can be clocked all the way up to 768.
Please read the forums before complaining it doesn't do something.

How do you over clock?

Does anyone know how to over clock you're DI to say 1.2? Thanks for any help.

You first need to root your phone, then install a kernel that is compatible with whatever rom you are using, then you need to install an OCing app like SetCPU and adjust accordingly.

I'm rooted running the 2.2 RUU and I have set cpu. So do I just need a kernal? Which one?

i reccomend King Kernel bfs #4, best freaken kernel ever... its located... here

so when i install this kernal is it ok to just bump the cpu speed up to 1.2? are there any guides to do this?

A lot of factors come into play when you start overclocking, every rom will respond differently.
The first thing to do before anything is to do a complete nandroid back up.
When overclocking keep in mind that the more you overclock the more chances you have of making your system unstable.
I have experimented a quite a bit and I have found that the King Kernal #4 seems to work well for me and at 1.2 it seems to be pretty stable. Any higher than that and my phone will sometimes re-boot itself for no apparent reason.
Again, your rom may handle things different so experiment and see what works best for you.
And remember - Do a complete backup first!

I'm using the number 4 kernal and it only goes to 1.19 is this what you mean by 1.2? I have to keep mine at 1.1 ghz at 1.19 my di gets unstable

Ya that's as high as they can oc these chips. I can only get to 115 safely 119 just crashes. But the charging experience will be better than stock with the BFS #4.

Could you guys please tell me what your settings for setcpu are?
I want better battery life and a faster cpu but im noticing that my phone almost needs a wake up time when i come out of screen off.
Thanks so much

If you are experiencing slow wake up, try increasing the min cpu speed to something around 460. Better batt life and increased speed takes a lot of experimenting. Your OC speed might differ from others due to differences in the phones cpu. For example, I have never been able to oc to 1.19 without the phone freezing or rebooting. My phone can handle 1152 but 1113 is perfect. In my opinion, ROMs have something to due with best batt-speed combo. I am running Ruby 1.1.1 with a setcpu profile of Screen off=245 without any wake lag. Other ROMs I have tried had wake up lag at that speed profile.
My set up:
(ROM-ASOP) Ruby 1.1.1
King's #1 ASOP "I told you so"- only works with ASOP
With the ROM's "Gem" performance scaling setting off, I use setcpu to OC to 1113, min is 245. I have a profile set to SCREEN OFF = 384 max/245 min.
I haven't worried about battery life since I started using King's kernals (I've tried them all with every compatible ROM on xda). I have several posts elsewhere on XDA showing 12 plus hours on a single bump charge and heavy phone use. Good enough for me. Stock cpu speed plus Sense ROM seems slow to me now.....to each his own though.

I hope to get some help because i value the opinions of those on this forum. Currently i am running virtuous 2.7 with virt. kernal v2. I am rooted, s-off, 2.15.xx radio. I want performance without draining my battery. What are the best settings to use in setcpu?
I did try king's kernal #4, but it was rebooting. switched kernals this morning.

One other app I use in conjunction with SetCPU is MinFreeManager. This will readjust your free ram to a higher standard. But with SetCPU I have it at 1113/Ondemand with no custom profiles. One other thing I really don't set is the Set on Boot option. I don't know why but I do. So with SkyRaider Vanilla 3.0 RC3/ KingX Kernel #4/ and MinFreeManager my phone fly's. I can't say for certain what settings you need for your phone but 1113-1115 is preferred by "most" phones and keep the set on boot option off. I keep a Galaxy S live wallpaper running and pandora while browsing the web and no lag what-so-ever.
CyanogenMod 6.0.2 and KingX kernel #1 with the same setup runs almost as smooth.
Hope this helps you out.

[Q] Calk's Preset Profiles to save battery question?

Notes about Battery Saver script
Can be used with kernels that have init.d support
It completely eliminates the need for an application to set CPU speeds or profiles
Easily customizable if you use a text editor(scripts located in /system/etc/init.d)
It will set Max CPU speed to 500MHz & Min CPU speed to 200MHz when a sleep
If SetCPU, Overclock Widget, Android Overclock or QuickClock Advanced Overclock are detected, the script is ignored, so it will not affect them
Preset profiles are:
1.2GHz - 100-85%
1.0GHz - 84-36%
800MHz - 35-0%
And just an FYI, even at 800MHz, the phone still operates very well & smooth but the battery saving are the real benefit
Click to expand...
Click to collapse
Does this mean that if I don't use Set CPU or any app that undervolt it, the phone will AUTOMATICALLY drop the CPU speed according to my battery level:
1.2GHz - 100-85%
1.0GHz - 84-36%
800MHz - 35-0%
Another word, it will automatically drop CPU speed to 800 MHZ when my battery level is 35-0% in order to save battery?

It won't "Drop" the CPU speed, it will lower the Maximum speed the CPU is allowed to ramp up to.

So if I am not doing CPU intensive stuff and just play simple games, email, web surfing phone call, then I am not going to see battery improvement since my CPU probably don't ramp past 800MHZ anyway when I am just doing simple stuff.?

Calk's ROM undervolts the CPU at all speeds so that in itself should help a little with battery life. But you are correct, if you are not doing CPU intensive tasks the CPU probably isn't spending much time at the higher speeds.
There is an app called CPUSpy which shows how much time the CPU has spent in each frequency state.

Your phone will ramp up to 1200 mhz more than you think. When it loads a webpage, it will ramp up to 1200, when it's loading your "simple" game, it will max out for a bit, etc.
It might not stay there for very long, but still. The nice thing about Calkuins rom is that even at 800 mhz, the phone is super smooth and lag free. In fact I just turn setcpu down to 800 all the time.

Let me research setcpu and play around with it. Thanks again for the quick answers.

The way Calkulin's rom scripts are setup, setcpu gets reset on every reboot, even if you have it set to boot settings. The scripts installed will still take priority and the old rules apply, just to let you know. So you would have to set setcpu every boot for it to work, that or remove the scripts.

Team era... Does the same idea apply to the blazer 2.0 battery saving script? or does tegrak break it?
Sent from my SPH-D710 using xda premium

I havnt opened that rom, but Im gonna say the same applies, I remove those scripts, 2 will affect the cpu state.
edit, let me clarify, the scripts take prority, even if the app makes a script for init.d, the original script will take over on a reboot. So the script breaks tegrak, setcpu, and voltage control unless you set the app on every reboot.

I am running Calks 2 and desperado kernel. I notice when using setcpu, if you have it set on boot, it will override calks script.
His script does work well on saving battery life though. I ran oc'd while at 20% and still had 1700mhz blazing on performance gov.
I'd still use Calks script over setcpu or tegrak only due to the fact im too sporatic with my phone use to create optimal profiles to fit the way and when i need to use the device.

Actually in my own testing setcpu will not override the scripts, the slider may stay the same, but trust me, it goes back to 800 (or 1200 over 86%batt), Ive tested it several times. If you want proof Ill tell you how to figure it out. I know Im not respected yet, but I am someone that is known under another name that is highly respected, so, take it as you will.
Sent from my SPH-D710 using xda premium

Era, what's your suggestion for keeping the battery saving scripts running and getting a 1500 ish over clock when needed... something that can do both without having to physically change setcpu everytime. I basically want to permanently over clock to 1.5 and still save as much battery as possible when i have the screen off or it is charging. Idk if setcpu profiles work on this phone because i know they did not work correctly on the galaxy s. And one final question... what voltages do u run at what speeds on the "desperado" kernel to undervolt efficiently?

ERA. I wasn't looking to say that you were wrong in any way shape or form. I would be interested to know how you seen this as I am still in the beginning phases of learning the android system. I do plan on writing my own kernal/roms but I was actually sharing what my logical thought process would have been given the apps and system info I had avail.
I have a little ways to go in understanding the structure and FS of droid. Time is everyones enemy. Thanks for the correction again!

I'm currently running Calkulin's rom v2.5, and even at 41% battery I notice the cpu still hits 1.2 Ghz. Is his script activated by default or am I overlooking something? I also have nothing like setcpu installed.

[Q] good overclock tool?

can anyone suggest a good overclock tool with voltage parameters? setcpu doesn't seem to have one for the play... and antutu seems bugged when setting voltages... (keeps changing the value for 1300mhz to 1300mv)

I'm using Antutu CPU Master Pro and I don't find it buggy. This is better to use imo than setcpu which consumes more battery. Longpress the frequency you are in and using then set to -25mv. Tick on "set on boot" then click "apply". Reboot your phone and check again your settings if it was changed or not. Also, try to reinstall your overclocking app and clear some cache on your phone.

i do agree that antutu is very good... but the problems started when i updated to 2.5... i was using 2.3 before
is -25 the lowest it can go??? isnt -50 safe?
EDIT: also in 2.5 it keeps saying that it has been granted superuser permissions... in 2.3 it only does that whenever i change any setting...

I use OC/UV Beater2v1.7, and it's awesome! Unlike setcpu, it won't run in the background, but rather sets up scripts in init.d (don't set as permanent unless you're 100% sure of your OC/UV settings, otherwise bootloops can occur)

I use 2.3.1 version. I tried -50 on setcpu and it crashed my phone. Haven't tried -50 yet on Antutu. I rolled back my speed from 1.5ghz to around 900+mhz as the speed is still fast (btw im using T.E.A.M. rom).

problem with overclock

My phone freezes just as or very soon after i choose to overclock in cm7 settings.
My last WFS was really loving the O/C.
Has anyone any solution. Many thanks
Edit: I can use userspace govenor and go to 806mhz but dont notice any difference in speed of hone. Tried cpu spy

Perhaps it's your kernel. Which kernel do you use? (go to Settings, About Phone, Software, More, Kernel version)
Also, what apps do you use to do the overclock?

It's likely your phone. Not all chips are made the same. Set your governor to performance and slowly ramp her up till it freezes. Then take a step down and leave it.
