LINSYSFS(5) FreeBSD File Formats Manual LINSYSFS(5)
NAME
linsysfs - Linux kernel objects file system
SYNOPSIS
linsys /compat/linux/sys linsysfs rw 0 0
DESCRIPTION
The Linux system file system, or linsysfs, emulates a subset of the Linux
sys file system and is required for the complete operation of some Linux
binaries.
The linsysfs 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
scsi_host class with a device symlink to the PCI directories of the
devices.
Each device node is a directory containing some files and directories:
host A place holder for storage host information.
pci_id A directory for the pci_id that contains either the device
information or another directory structure for a PCI bridge.
Each host node of scsi_host is a directory containing some files and
directories:
proc_name The Linux registered driver name for these devices.
device A symlink to the PCI device directory.
FILES
/compat/linux/sys The normal mount point for
linsysfs.
/compat/linux/sys/class/scsi_host The storage host node.
/compat/linux/sys/devices/pci0000:00 The PCI device hierarchy node.
EXAMPLES
The most common usage follows:
mount -t linsysfs linsys /compat/linux/sys
where /compat/linux/sys is a mount point.
