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, brain**** 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:

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 package to be flashed through recovery though.

Does Wi-fi work?

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.

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.

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 like a normal rom/radio btw.

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