Is Kexec a possibility to load alternate kernel?

---

So I'm curious if it would be possible to build a kexec module to load another kernel of our choosing? What is everyones thoughts on this? I'm sure that someone has thought about this before...bit I find myself thinking about this and just wanted to know others thoughts...

As far as I know () it's just VERY hard to accomplish.

Ok...is that why we have not tried to go this route?

Basically its a module you can build in linux that will let you load an alternate kernel

So it is similar dual booting? That would be really cool.

i know kholk on the razr forum is working on it for the gsm razr, but idk how close he has gotten as there are no updates directly from him

kholk has an unsigned kernel running on the gsm razr, but has one cpu working instead of two, so it may be possible

I would be interested to see what he has and if there ia anything that we could do to incorporate it into what we would like to accomplish

While waiting for DZK to have a decent break from school, I have been talking with a great developer hashcode0f (Hashcode) about this exact thing. kexec _IS_ possible, however, very improbable at the moment. I've been looking into trying to build the 3.0 version of the kernel for the DX2, but things haven't been looking too good... Namely nVidia is VERY SLOW on releasing their sourcecode for both the kernel and the processor... :-/

Anyhow, back to kexec... Yes, it's possible, there is a developer for the RAZR that has kexec working, however it only fires up on one processor. That would not do to well on the DX2. I have been trying several things that "might" work for kernel space drivers, namely modprobe and insmod, but I'm not having much success with that either. (Damn locked boot loader!)

If there is anyone else here that has extensive Linux/Unix/*nix experience and has a DX2 and is willing to work with me on this, please PM me! Thanks!

Ciao!

how is putting kexec to use improbable at this moment? is it because of the kernel/hw release from nvidia?
