From cc53291521701f9c7c7265bbb3c140563174d8b2 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Sun, 4 Dec 2005 18:39:43 +1100 Subject: [PATCH] powerpc: Add arch dependent basic infrastructure for Kdump. Implementing the machine_crash_shutdown which will be called by crash_kexec (called in case of a panic, sysrq etc.). Disable the interrupts, shootdown cpus using debugger IPI and collect regs for all CPUs. elfcorehdr= specifies the location of elf core header stored by the crashed kernel. This command line option will be passed by the kexec-tools to capture kernel. savemaxmem= specifies the actual memory size that the first kernel has and this value will be used for dumping in the capture kernel. This command line option will be passed by the kexec-tools to capture kernel.
