CPU_DUMPCONF(9)            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.
