      [PATCH] kdump: Documentation for Kdump · b089f4a6
      Vivek Goyal authored
      This patch contains the documentation for the kexec based crash dump tool.
      
      Quick kdump-howto
      ================================================================
      
      1) Download and build kexec-tools.
      
      2) Download and build the latest kexec/kdump (-mm) kernel patchset.
         Two kernels need to be built in order to get this feature working.
      
        A) First kernel:
         a) Enable "kexec system call" feature:
      	CONFIG_KEXEC=y
         b) Physical load address (use default):
      	CONFIG_PHYSICAL_START=0x100000
         c) Enable "sysfs file system support":
      	CONFIG_SYSFS=y
         d) Boot into first kernel with the command line parameter "crashkernel=Y@X":
            For example: "crashkernel=64M@16M".
      
        B) Second kernel:
         a) Enable "kernel crash dumps" feature:
      	CONFIG_CRASH_DUMP=y
         b) Physical load addreess, use same load address as X in "crashkernel"
            kernel parameter in d) above, e.g., 16 MB or 0x1000000.
      	CONFIG_PHYSICAL_START=0x1000000
         c) Enable "/proc/vmcore support" (Optional, in Pseudo filesystems).
      	CONFIG_PROC_VMCORE=y
      
      3) Boot into the first kernel.
      
      4) Load the second kernel to be booted using:
      
         kexec -p <second-kernel> --crash-dump --args-linux --append="root=<root-dev>
         maxcpus=1 init 1"
      
      5) System reboots into the second kernel when a panic occurs. A module can be
         written to force the panic, for testing purposes.
      
      6) See Documentation/kdump.txt for how to read the first kernel's
         memory image and how to analyze it.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
