Hi, I am using kexec/kdump in my system for any crash. As we know, when the system crashes, the capture kernel copies the /proc/vmcore file into a predefined dump location (/var/log/dump) in the file system. I gone through the source code fs/proc/vmcore.c. Is this the file which creates the /proc/vmcore after a system crash because /proc/vmcore should be the image of whole physical memory and ELF fomatted? If not, can anybody let me know the source file name?
I think the pages in the vmcore should be in the following order. 1. Dump putbuf (header) 2. Kernel pages 3. Buffer cache pages 4. User pages 5. Free pages Am I correct? Thanks, Shan
