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.
