Hi, I'm working in a project and there I need use kexec code to do somethings. I read a lot of the kexec-tools code (user-land) and kexec-sys call (k-land) and I'd like to be sure about some arguments there.
In kexec we have that kexec_image and into it that nr_segments and the segments itself. I know that kernel image passed by kexec in user land (bzImage) is copy in a buffer and in kexe_load it receives the entry point for this new kernel (bzImage) and the start position where (I'm supposing ) start the kernel image. So , my question is, using that nr_segments or segemtns by itself can I determine the size of the bzImage/image in kexec-sys call? And these guesses about entry point and the address of start kernel image, is it correct? This is the kexec.c file (where we have the sys call and a bunch of another code). http://lxr.free-electrons.com/source/kernel/kexec.c -- ---------------------------------------------- Leônidas S.
