.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.
