IA64: reliable way to determine kdump_kernel?
|[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]|
What is a reliable way to determine whether the booting kernel is a production kernel or a kdump kernel? In setup_arch() routine of arch/ia64/kernel/setup.c, there is a statement as below: kdump_kernel = (strstr(saved_command_line, "elfcorehdr=") != NULL); This check is not true for an SN system. Is there a better way? How about "maxcpus=" ? Is maxcpus=1 always true for a kdump kernel? Thanks, - jay
