NAME
linsysfs —
Linux system file system
SYNOPSIS
linsys /compat/linux/sys linsysfs rw 0 0
DESCRIPTION
The Linux system file system, orlinsysfs, 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/syswhere /compat/linux/sys is a mount point.
