NAME

6       devfs - Devices file system
7

DESCRIPTION

9       The  devfs  filesystem  manages  a  name space of all devices under the
10       Solaris operating  environment  and  is  mounted  during  boot  on  the
11       /devices name space.
12
13
14       The  /devices  name  space is dynamic and reflects the current state of
15       accessible devices under the Solaris operating environment.  The  names
16       of all attached device instances are present under /devices.
17
18
19       The  content under /devices is under the exclusive control of the devfs
20       filesystem and cannot be changed.
21
22
23       The system may be configured to include a device in one of two ways:
24         By  means  of  dynamic  reconfiguration  (DR),  using,  for  example,
25         cfgadm(1M).
26         For   devices   driven   by   driver.conf(4)  enumeration,  edit  the
27         driver.conf file to add a new entry, then use update_drv(1M) to cause
28         the  system to re-read the driver.conf file and thereby enumerate the
29         instance.
30
31
32       The device may be attached through a number of system  calls  and  pro‐
33       grams,  including open(2), stat(2) and ls(1). During device attach, the
34       device driver typically creates minor nodes corresponding to the device
35       via ddi_create_minor_node(9F). If the attach is successful, one or more
36       minor nodes referring to the device are created under /devices.
37
38
39       Operations like mknod(2), mkdir(2) and creat(2) are  not  supported  in
40       /devices.

NOTES

50       The /devices name space cannot be unmounted.

53       All  content  at  or below the /devices name space is an implementation
54       artifact and subject to incompatible change or removal without  notifi‐
55       cation.
