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.
So i was looking around on App Brain for some rooted apps, and came across this. Figured i would give it a shot, figured no one had tried it yet on a dinc 2. And what do you know it works, Set my clock to 1.024, of course you have to be rooted to try this app. but since there aren't a lot of kernels out there, and the one that is doesnt work well with my rom, figure i will give this a shot for a while.
Anybody try this app? Confirm this works, seems to work for me.
I have used it, but it doesn't overclock because the stock cpu clock is 1GHz, or 1024MHz. I guess it could be used to underclocking, but thats about it.
Hmm seems to run a bit better...but who knows...at least its something until i can get a working kernel.
Any little bit helps
SetCPU overclocks right? I've got mine set at 1.305 MHz, but it has no modified Kernel, so I wanted to be sure that I'm really getting 1.3 GHz out of my processor

Download a system info app. Will tell you your CPU speed
sent from an under rated phone
I use it... I love it.
It even lets you set I/O scheduler.
Also, if your phone does an "unclean" reboot, the app wont apply your setting on next boot.
Setcpu will not overclock unless you have an oc kernal. You must be using a non-stock one.
Sent from my ADR6350 using XDA App
This app will give you your CPU stats so you can test, so you can underclock or overclock. Depending on what you want.
I am playing around with some other OC/UV apps other than SetCPU and was wondering, for those who do OC /UV /UC, what app do you prefer?
ive tried out (so far)
SetCPU
Voltage Control Extreme
AnTuTu CPU Master Pro
CPU Control Pro
ROM Toolbox Pro

Is there a way to make a shortcut to the performance settings, under settings?
i tried to make an action shortcut but haven't been able to. I myself don't play with UV often. If i could create a faster way to access the performance settings i would prob use it.

Dunno, never tried. Rarely need to adjust the settings, ROM runs well enough at 800mhz lol

I've had my A100 for a few weeks, up to now I've used AnTuTu CPU Master Pro to overclock and undervolt, hasn't failed me yet, originally used my ROMs built in settings but that began to be a bit tedious, constantly having to dig through my settings for it got a bit old, a convenient shortcut to the performance settings would be just dandy.

The only thing i find built in ROM performance settings lack is voltage control, generally liking my overclock/undervolt, performance is nice, generally pretty stable up to now.

I found overclocking the GPU helps a lot more. There is a kernel for jellybean rom (a.k.a. CM10) and may work for ICS and the GPU overclock helps a lot. Use built in CM over clocker @ 1.5 GHz and GPU @ <400 MHz or whatever speed the kernel builder put it at. The original GPU clock speed was around 350 MHz or something so that is a substantial boost in terms of speed. Other then some heating when playing games no problems and perfectly stable. Battery doesn't seem to drop a bit maybe 1 or 2% faster.

Wanna get real crazy push it to 430 GPU and 1.7 cpu. Quite an interesting ride. The kernels are all compatible with ICS or jb, just don't get the ui acceleration in ICS.

He did one that high? I built that one myself lol.
Good call pulling them down if he did though, not all devices can handle it. The old board did, the replacement didn't take it so well.

hello, i use setcpu pro. set on boot 1.0ghz. uv is on test. i read many pages, the result is all -100 the last three cpu steps -75 -50 -25. on hd gaming (wild blood, nfs undercover...) set 1,2ghz. 800mhz is more better for the battery and all running smooth. (many times with livewallpaper). for music when i going to the city ... my system: a101 - flexreaper rev2, ezterry kernel (ezT20), apex launcher.
setcpu can not ov the GPU. which programm can do this?

Your English is not too bad my new friend. Thank you for your feedback. I like to find out what programs and settings users are using on their A100s. Helps me find different options to try on my tablet.
I love SetCPU and have PRO version as well, but it was causing bad SOD problems on my tablet. I am now currently testing others.

I use system tuner. Works pretty good and has lots of other useful tweaks in it
The new JMT JB 2.1 is overclocked to 1.8 ghz does anyone know how to downclock it back to stock
call me paranoid but my phone heats up a lot in 3d games dont want to fry my phone
for the life of me I cant find where to change it like in previous JMT roms...

Since it's OC'd by default that is what any kernel tuner will show. That it's not OC'd. Just reduce it to what you want under CPU settings. Or do you mean kernel tuner is showing max at 1.2 (or whatever it is), and not 1.8?
thanks for your help... I've actually changed the mod back to v1.1
was having problems when on data would freeze... back to the stock kernel
I appreciate your input m8
Anyone know how to fix the Governor settings not sticking? I am on the vs985 (vzw) I am rooted and have kernel tweaker installed.
