CPU_DUMPCONF(9) FreeBSD Kernel Developer's Manual CPU_DUMPCONF(9)
NAME
cpu_dumpconf, cpu_dump, cpu_dumpsize, dumpsys - machine-dependent kernel
core dumps
SYNOPSIS
#include <sys/types.h>
#include <sys/systm.h>
void
cpu_dumpconf(void);
int
cpu_dump(int (*dump)(dev_t, daddr_t, void *, size_t), daddr_t *blknop);
int
cpu_dumpsize(void);
void
dumpsys(void);
DESCRIPTION
cpu_dumpconf() is the machine-dependent interface invoked during system
bootstrap to determine the dump device and initialize machine-dependent
kernel core dump state. Internally, cpu_dumpconf() will invoke
cpu_dumpsize() to calculate the size of machine-dependent kernel core
dump headers.
dumpsys() is invoked by cpu_reboot() to dump kernel physical memory onto
the dump device. dumpsys() invokes cpu_dump() to write the machine-
dependent header to the dump device at block number *blknop using the
dump device's PIO dump routine specified by the dump argument.
cpu_dumpsize(), cpu_dump(), and dumpsys() are parts of the machine-
dependent interface, however they are not exported to machine-independent
code.
