.Sh DESCRIPTION
|
|
The
|
|
.Tn Linux
|
|
system file system, or
|
|
.Nm ,
|
|
emulates a subset of the
|
|
.Tn Linux

|
|
the complete operation of some
|
|
.Tn Linux
|
|
binaries.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
provides a two-level view of devices.
|
|
At the highest level, PCI devices themselves are named, according to
|
|
their bus, slot and function in the system hierarchy.
|
|
PCI storage devices are listed in the
|
|
.Pa scsi_host
|
|
class with a device symlink
|
|
to the PCI directories of the devices.
|
|
.Pp
|
|
Each device node is a directory containing some files and directories:
|
|
.Bl -tag -width ".Pa status"
|
|
.It Pa host
|
|
A place holder for storage host information.
|
|
.It Pa pci_id
|
|
A directory for the
|
|
.Pa pci_id
|
|
that contains either the device information or another directory structure
|
|
for a PCI bridge.
|
|
.El
|
|
.Pp
|
|
Each host node of scsi_host is a directory containing some files and directories:
|
|
.Bl -tag -width ".Pa proc_name"
|
|
.It Pa proc_name
|
|
The
|
|
.Tn Linux
|
|
registered driver name for these devices.
|
|
.It Pa device
|
|
A symlink to the PCI device directory.
|
|
.El
|
|
.Sh FILES
|
|
.Bl -tag -width ".Pa /compat/linux/sys/devices/pci0000:00" -compact
|
|
.It Pa /compat/linux/sys
|
|
The normal mount point for
|
|
.Nm .
|
|
.It Pa /compat/linux/sys/class/scsi_host
|
|
The storage host node.
|
|
.It Pa /compat/linux/sys/devices/pci0000:00
|
|
The PCI device hierarchy node.
|
|
.El
|
|
.Sh EXAMPLES
|
|
The most common usage follows:
|
|
.Pp
|
|
.Dl "mount -t linsysfs linsys /compat/linux/sys"

|
.Pa /compat/linux/sys
|
|
is a mount point.
