# $FreeBSD$ # # This list is semi-obsoleted by DEVFS, but for now it still contains # the current allocation of device major numbers. # # Unless very special circumstants demand otherwise, all device drivers # are able to use a dynamically allocated major number. If the d_maj # element of the cdevsw is uninitialized (preferred) or initialized to # MAJOR_AUTO, this dynamic allocation will happen. # # NOTICE: FreeBSD does not use block major numbers anymore, you neither # need to assign nor use a block major number for any device driver any # more. # # The names marked with a '*' is belived to be allocated for code inside # the CVS tree. # #maj name comments 0 *cn console 1 *ctty /dev/tty 2 *mm /dev/mem,kmem,etc 4 *geom GEOMetry 5 *pts pseudo tty "tty" half 6 *ptc pseudo tty "master" half 7 *log system log 19 *tw X-10 power interface 22 *fd (/dev/stdin etc) 30 *snd sound driver system 32 lkmc Loadable Kernel Module Controller 33 lkm assigned to Loadable Kernel Modules 34 lkm assigned to Loadable Kernel Modules 35 lkm assigned to Loadable Kernel Modules 36 lkm assigned to Loadable Kernel Modules 37 lkm assigned to Loadable Kernel Modules 38 lkm assigned to Loadable Kernel Modules 42 *cx Cronyx/Sigma serial adapter 43 vn vnode "disk" device (retired) 46 - - 54 OLDnic ISDN system 58 - Was dgb: Digiboard PC/Xe 62 worm SCSI "worm type" 64 ??
