CPU_ROOTCONF(9)        NetBSD 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.
