.Dd May 24, 2002 .Dt CPU_DUMPCONF 9 .Os .Sh NAME .Nm cpu_dumpconf , .Nm cpu_dump , .Nm cpu_dumpsize , .Nm dumpsys .Nd machine-dependent kernel core dumps .Sh SYNOPSIS n sys/types.h n 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.

p .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.

p .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. .Sh SEE ALSO .Xr cpu_reboot 9
