While humans may be able to understand that something like: /sys/bus/rapidio/devices/nn:d:iiii could actually mean: /sys/bus/rapidio/devices/00:e:0000 This is something that computers can't easily identify. As get_abi.pl needs to convert it into a regex, change What: lines to: /sys/bus/rapidio/devices/<nn>:<d>:<iiii> Which is the commonly-used pattern on ABI files for wildcards.

What: /sys/bus/rapidio/devices/:: Description: For each RapidIO device, the RapidIO subsystem creates files in an individual subdirectory with the following name format of device_name "nn:d:iiii", where:
==== ========================================================
nn two-digit hexadecimal ID of RapidIO network where the
device resides
d device type: 'e' - for endpoint or 's' - for switch
iiii four-digit device destID for endpoints, or switchID for
switches
==== ========================================================
For example, below is a list of device directories that
represents a typical RapidIO network with one switch, one host,
and two agent endpoints, as it is seen by the enumerating host
(with destID = 1)::
/sys/bus/rapidio/devices/00:e:0000
/sys/bus/rapidio/devices/00:e:0002
/sys/bus/rapidio/devices/00:s:0001
NOTE:
An enumerating or discovering endpoint does not create a
sysfs entry for itself, this is why an endpoint with destID=1
is not shown in the list.

This attribute is similar in behaviour to the "config" attribute of PCI devices and provides an access to the RapidIO device registers using standard file read and write operations.
RapidIO Switch Device Attributes
RapidIO switches have additional attributes in sysfs. RapidIO subsystem supports common and device-specific sysfs attributes for switches. Because switches are integrated into the RapidIO subsystem, it offers a method to create device-specific sysfs attributes by specifying a callback function that may be set by the switch initialization routine during enumeration or discovery process.
What: /sys/bus/rapidio/devices/::/routes
Date: Nov, 2005
KernelVersion: v2.6.15
Contact: Matt Porter mporter@kernel.crashing.org,
Alexandre Bounine alexandre.bounine@idt.com
Description:
(RO) reports switch routing information in "destID port" format.
This attribute reports only valid routing table entries, one
line for each entry.
What: /sys/bus/rapidio/devices/::/destid
Date: Mar, 2011
KernelVersion: v2.6.3
Contact: Matt Porter mporter@kernel.crashing.org,

Description:
(RO) device destination ID of the associated device that defines
a route to the switch
What: /sys/bus/rapidio/devices/::/hopcount
Date: Mar, 2011
KernelVersion: v2.6.39
Contact: Matt Porter mporter@kernel.crashing.org,
Alexandre Bounine alexandre.bounine@idt.com
Description:
(RO) number of hops on the path to the switch
What: /sys/bus/rapidio/devices/::/lnext
Date: Mar, 2011
KernelVersion: v2.6.39
Contact: Matt Porter mporter@kernel.crashing.org,
Alexandre Bounine alexandre.bounine@idt.com
Description:
(RO) returns names of devices linked to the switch except one of
a device linked to the ingress port (reported as "lprev"). This
is an array names with number of lines equal to number of ports
in switch. If a switch port has no attached device, returns
"null" instead of a device name.
Device-specific Switch Attributes

KernelVersion: v2.6.37
Contact: Matt Porter mporter@kernel.crashing.org,

Description:
(RO) reads contents of device error log until it is empty.
RapidIO Bus Attributes
What: /sys/bus/rapidio/scan Date: May, 2013 KernelVersion: v3.11 Contact: Matt Porter mporter@kernel.crashing.org, Alexandre Bounine alexandre.bounine@idt.com Description: (WO) Allows to trigger enumeration discovery process from user space. To initiate an enumeration or discovery process on specific mport device, a user needs to write mport_ID (not RapidIO destination ID) into this file. The mport_ID is a sequential number (0 ... RIO_MAX_MPORTS) assigned to the mport device. For example, for a machine with a single RapidIO controller, mport_ID for that controller always will be 0. To initiate RapidIO enumeration/discovery on all available mports a user must write '-1' (or RIO_MPORT_ANY) into this attribute file.
