Hello List, I have a project requirement and I was wondering whether it would be possible to solve it using kexec. I want to run a minimalist Linux OS on a x86 processor based system, I will supply a fixed memory range to the kernel on boot to limit the physical RAM used. On shutdown I want to completely overwrite all RAM used by the previously running image. I thought I could use kexec to load a REALLY simple image whose sole purpose is to overwrite the RAM used by the previous kernel and then shut the system down. We have a number of 16bit real mode applications (they utilise flat real mode) that could possibly be used to realise this feature. They are normally loaded to 09E0:0000. Can kexec load non-linux images? Do you think it could load one of our applications and execute it? I see there's a kexec_test program in the 2.0.5 tarball but was wondering what that does? Can kexec load and execute that?
Any help really appreciated.
