CPU_DUMPCONF(9) 					   BSD Kernel Developer's Manual					   CPU_DUMPCONF(9)

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.

CPU_REBOOT(9)						   BSD Kernel Developer's Manual					     CPU_REBOOT(9)

cpu_reboot -- halt or reboot the system SYNOPSIS
#include <sys/reboot.h> void cpu_reboot(int howto, char *bootstr); DESCRIPTION
The cpu_reboot() function handles final system shutdown, and either halts or reboots the system. The exact action to be taken is determined by the flags passed in howto and by whether or not the system has finished autoconfiguration. If the system has finished autoconfiguration, cpu_reboot() does the following: 1. Sets the boothowto system variable (see boothowto(9)) from the howto argument. 2. If this is the first invocation of cpu_reboot() and the RB_NOSYNC flag is not set in howto, syncs and unmounts the system disks by calling vfs_shutdown(9) and sets the time of day clock by calling resettodr(9). 3. Disables interrupts. 4. If rebooting after a crash (i.e., if RB_DUMP is set in howto, but RB_HALT is not), saves a system crash dump. 5. Runs any shutdown hooks by calling pmf_system_shutdown(9). 6. Prints a message indicating that the system is about to be halted or rebooted. 7. If RB_HALT is set in howto, halts the system. Otherwise, reboots the system. If the system has not finished autoconfiguration, cpu_reboot() runs any shutdown hooks by calling pmf_system_shutdown(9), prints a message, and halts the system. If RB_STRING is set in howto, then the parameter bootstr is passed to the system boot loader on some ports. SEE ALSO
