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.
