-------------------------------------------------------
+Build the system and dump-capture kernels
+-----------------------------------------
+There are two possible methods of using Kdump.
-Download the mainline (vanilla) kernel source code (2.6.13-rc1 or newer)
-from http://www.kernel.org. Two kernels must be built: a system kernel
-and a dump-capture kernel. Use the following steps to configure these
-kernels with the necessary kexec and Kdump features:
+1) Build a separate custom dump-capture kernel for capturing the
+ kernel core dump.
-System kernel
--------------
+2) Or use the system kernel binary itself as dump-capture kernel and there is
+ no need to build a separate dump-capture kernel. This is possible
+ only with the architecutres which support a relocatable kernel. As
+ of today i386 and ia64 architectures support relocatable kernel.
+
+Building a relocatable kernel is advantageous from the point of view that
+one does not have to build a second kernel for capturing the dump. But
+at the same time one might want to build a custom dump capture kernel
+suitable to his needs.
+
+Following are the configuration setting required for system and
+dump-capture kernels for enabling kdump support.

+can choose to load the uncompressed vmlinux or compressed bzImage/vmlinuz
+of dump-capture kernel. Following is the summary.
+
+For i386:
+ - Use vmlinux if kernel is not relocatable.
+ - Use bzImage/vmlinuz if kernel is relocatable.
+For x86_64:
+ - Use vmlinux
+For ppc64:
+ - Use vmlinux

+If you are using a uncompressed vmlinux image then use following command

- --append="root=<root-dev> init 1 irqpoll"
+ --append="root=<root-dev> <arch-specific-options>"
+
+If you are using a compressed bzImage/vmlinuz, then use following command
+to load dump-capture kernel.
+
+ kexec -p <dump-capture-kernel-bzImage> \
+ --initrd=<initrd-for-dump-capture-kernel> \
+ --append="root=<root-dev> <arch-specific-options>"
+
+Following are the arch specific command line options to be used while
+loading dump-capture kernel.

+For ppc64:

+For IA64
+ (To be filled)
Notes on loading the dump-capture kernel:
-* <dump-capture-kernel> must be a vmlinux image (that is, an
- uncompressed ELF image). bzImage does not work at this time.
-
* By default, the ELF headers are stored in ELF64 format to support
systems with more than 4GB memory. The --elf32-core-headers option can
be used to force the generation of ELF32 headers. This is necessary
@@ -231,6 +308,9 @@
* "init 1" boots the dump-capture kernel into single-user mode without
networking. If you want networking, use "init 3."
+* We generally don' have to bring up a SMP kernel just to capture the
+ dump. Hence generally it is useful either to build a UP dump-capture
+ kernel or specify maxcpus=1 option while loading dump-capture kernel.
