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.
I have installed a light version of Revolution HD rom and am not overclocking past defaults.
I do however want to undervolt. ATM ive set screen off profile to max out at 600 - what can i do do undervolt?
Can i keep the rom but flash a different kernel? If so, which one?
The kernal that rom uses is already undervolted, so you dont really need to unless you want to try and squeeze it as absolutely low as your handset will allow.
i see - where do i find the exact details of this?
This is the thread for the kernal that Revolution HD uses.
http://forum.xda-developers.com/showthread.php?t=835608
thanks, but from what i understand the kernel isnt undervolted - its unvolted...
Hmm, i was under the impression that lower freqs were undervolted and as it approaches 1.2Ghz the voltage approaches the highest value of stock voltage.
even if this was so - i would see no benefit as i use stock max clocks
Hi,
Sorry if this has been posted before but I can't find an answer to this question
I am currently running AOKP and trinity kernel, 1344mhz (cpu) and 499mhz (gpu). After installing the kernel, I manually went into ROM control, and increased the CPU to 1344mhz - set on boot. That was the CPU overclocked
However, I can't figure out how to overclock the GPU? I have run a benchmark, and it seems to still be at stock, and not 499mhz - how do I set it to the 499mhz that the kernel allows?
Thanks

There is a command that you can run from terminal on your phone but I can't think of it right now. Also, a bit of searching seems that there is an app. I haven't tested to see if it works, but it says it OCs the CPU AND GPU. Look for Overclocking(GPU + CPU) in google.

That one apparently doesn't work.. have also tried Antutu CPU Master pro but it doesn't support GPU overclocking on the Galaxy Nexus...
Afaik, gpu oc is only available, if built-in the kernel. Userland controlled gpu oc must be supported by the kernel first, thats probably why antutu pro master or any other app still can't do it.

I'm quite happy with the stock ROM. Is it possible to overclock it? Do I just need to install a overclockable kernel? Will I lose any functionality due to bugs/etc? What's the most reliable kernel for O/C?
Thanks,
Nick
It is possible to OC it only via a custom kernel.............so i recommend that you try the Dust kernel by einstein.frat
Yea he's right. what you need is only being rooted and recovery for flashing kernel..and of course a program which controls your cpu such as setcpu..
i recommend you kernel that cm7 used with last update. it supports 864mhz even and with no stuck( and battery drain )if you search for it on xda i am sure you will find..

In any way......DO NOT use the CM7 kernel...........an AOSP kernel is a bit different from the Stock(sense) one.................................it won't work
Thanks all. It looks like I'll give the dust kernel a try.
Are there preset CPU MHz settings for overclocking or is any integer value allowable? Most of the overclocking threads talk about 768Mhz, 806Mhz. My guess it's probably constrained by some clock multiplier factor.
oww i am happy to learn that
Plzzz reply which wills sbe the best overclock kernel for stock miui 12
Hi i have ARHD on my phone with the XM Kernel. I was slightly suprised in the Trickster MOD app, the max clock speed is 1.3ghz. Yes i know i can OC to 1.5 but im not sure what is setting this. When i had ARHD installed with stock kernel it was showing 1.3 as default. I assume that was set by the ROM. But i installed this kernel and still has 1.3 as the default.
Also the default govenor settings for the gaming one has the boost_freq set at 1300000, which is 1.3ghz, that can be changed to 1.5 also. But surely the boost freq would be the max freq no matter if you move the slider to 1.5 in the basic controls? But i would be suprised that the gaming govenor would underclock the cpu, surely for gaming you would want the phone maxed out?
Is this expected with the XM Kernel and the ARHD? And if so, is there any things i can change in the govenor settings to make sure it performs at absolute max?
It's kernel related; Xmisters' kernels since 188 have a hard cap(1.3Ghz) by default, but using trickster mod, or another o/c apk, you can raise it to the stock 1.5Ghz(tick 'set on boot' to ensure it stays at 1.5) The best settings are trial and error, tbh, I use touchdemand/sio though smartmax seems to be the best balance.
Thanks for the answer. i can change it to 1.5 easy enough, but if you look in the govenor control, the boost_freq is is set to 1300000. If i left it at that, would it prevent the cpu from going up to 1.5?

you have sleep (lowest CPU can go), ideal freq(the speed the CPU aims for while awake), touch poke (when you touch the screen), boost (what it boosts too to prevent lag) and max (CPU flat out)
Setting the boost to 1.3 will still allow the could to run at full speed.

That makes sense, cheers. So its probably a good idea to leave it as it is then.
