+.Sh NAME
+.Nm cpu_dumpconf ,
+.Nm cpu_dump ,
+.Nm cpu_dumpsize ,

+.Nd machine-dependent kernel core dumps
+.Sh SYNOPSIS
+.In sys/types.h
+.In sys/systm.h
+.Ft void
+.Fn cpu_dumpconf "void"
+.Ft int
+.Fn cpu_dump "int (*dump)(dev_t, daddr_t, void *, size_t)" "daddr_t *blknop"
+.Ft int
+.Fn cpu_dumpsize "void"
+.Ft void
+.Fn dumpsys "void"
+.Sh DESCRIPTION
+.Fn 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,
+.Fn cpu_dumpconf
+will invoke
+.Fn cpu_dumpsize
+to calculate the size of machine-dependent kernel core dump headers.
+.Pp
+.Fn dumpsys
+is invoked by
+.Fn cpu_reboot
+to dump kernel physical memory onto the dump device.
+.Fn dumpsys
+invokes
+.Fn cpu_dump
+to write the machine-dependent header to the dump device at block number
+.Fa *blknop
+using the dump device's PIO dump routine specified by the
+.Fa dump
+argument.
+.Pp
+.Fn cpu_dumpsize ,
+.Fn cpu_dump ,
+and
+.Fn dumpsys
+are parts of the machine-dependent interface, however they are not
+exported to machine-independent code.
