# Kernel Version string for the -kdump kernel, such as 2.6.13-1544.FC5kdump
# If no version is specified, then the init script will try to find a
# kdump kernel with the same version number as the running kernel.
KDUMP_KERNELVER=""

# The kdump commandline is the command line that needs to be passed off to
# the kdump kernel.  This will likely match the contents of the grub kernel
# line.  For example:
#   KDUMP_COMMANDLINE="ro root=LABEL=/"
# Dracut depends on proper root= options, so please make sure that appropriate
# root= options are copied from /proc/cmdline. In general it is best to append
# command line options using "KDUMP_COMMANDLINE_APPEND=".
# If a command line is not specified, the default will be taken from
# /proc/cmdline
KDUMP_COMMANDLINE=""

# This variable lets us remove arguments from the current kdump commandline
# as taken from either KDUMP_COMMANDLINE above, or from /proc/cmdline
# NOTE: some arguments such as crashkernel will always be removed
KDUMP_COMMANDLINE_REMOVE="hugepages hugepagesz slub_debug quiet log_buf_len swiotlb"

# This variable lets us append arguments to the current kdump commandline
# after processed by KDUMP_COMMANDLINE_REMOVE
KDUMP_COMMANDLINE_APPEND="irqpoll maxcpus=1 reset_devices novmcoredd"

# Any additional kexec arguments required.  In most situations, this should
# be left empty
#
# Example:
#   KEXEC_ARGS="--elf32-core-headers"
KEXEC_ARGS=""

#Where to find the boot image
#KDUMP_BOOTDIR="/boot"

#What is the image type used for kdump
KDUMP_IMG="vmlinuz"

# Logging is controlled by following global variables:
#   - @var kdump_stdloglvl - logging level to standard error (console output)
#   - @var kdump_sysloglvl - logging level to syslog (by logger command)
#   - @var kdump_kmsgloglvl - logging level to /dev/kmsg (only for boot-time)
# If any of the variables is not set, this function set it to default:
#   - @var kdump_stdloglvl=4 (info)
#   - @var kdump_sysloglvl=4 (info)
#   - @var kdump_kmsgloglvl=0 (no logging)
#
# Logging levels: fatal(1),error(2),warn(3),info(4),debug(5),trace(6)
#
# For example: the following configurations indicate that kdump messages will be printed
# to console and journald for debugging case.
# kdump_sysloglvl=5
# kdump_stdloglvl=5
