CPU_DUMPCONF(9) 					   BSD 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-depen-
     dent 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.

CRASHINFO(8)						    BSD System Manager's Manual 					      CRASHINFO(8)

NAME

     crashinfo -- analyze a core dump of the operating system

SYNOPSIS

     crashinfo [-d crashdir] [-n dumpnr] [-k kernel] [core]

DESCRIPTION

     The crashinfo utility analyzes a core dump saved by savecore(8).  It generates a text file containing the analysis in the same directory as
     the core dump.  For a given core dump file named vmcore.XX the generated text file will be named core.txt.XX.

     By default, crashinfo analyzes the most recent core dump in the core dump directory.  A specific core dump may be specified via either the
     core or dumpnr arguments.	Once crashinfo has located a core dump, it analyzes the core dump to determine the exact version of the kernel
     that generated the core.  It then looks for a matching kernel file under each of the subdirectories in /boot.  The location of the kernel
     file can also be explicitly provided via the kernel argument.

     Once crashinfo has located a core dump and kernel, it uses several utilities to analyze the core including dmesg(8), fstat(1), iostat(8),
     ipcs(1), kgdb(1), netstat(1), nfsstat(1), ps(1), pstat(8), and vmstat(8).

     The options are as follows:

     -d crashdir
	     Specify an alternate core dump directory.	The default crash dump directory is /var/crash.

     -n dumpnr
	     Use the core dump saved in vmcore.dumpnr instead of the latest core in the core dump directory.

     -k kernel
	     Specify an explicit kernel file.

HISTORY

     The crashinfo utility appeared in FreeBSD 6.4.
