CPU_ROOTCONF(9) BSD Kernel Developer's Manual CPU_ROOTCONF(9)
NAME
cpu_rootconf, rootconf, setroot -- root file system setup
SYNOPSIS
#include <sys/types.h>
#include <sys/systm.h>
void
cpu_rootconf(void);
void
rootconf(void);
void
setroot(device_t bootdv, int bootpartition);
DESCRIPTION
The cpu_rootconf() is a machine-dependent interface invoked during system bootstrap to determine the root file system device and initialize
machine-dependent file system state. cpu_rootconf() provides the global variables booted_device, booted_partition, booted_startblk and
booted_nblks and invokes the machine-independent function rootconf which rootconf then calls the function setroot to record the boot/root
device and the boot partition information for use in machine-independent code.
For disk boot, if booted_nblks is not 0, then booted_startblk and booted_nblks are supposed to specify a disk wedge that is used as the root
device. Otherwise the booted_partition is used.
