+What: /sys/bus/rapidio/devices/nn:d:iiii
+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.

+Description:
+ (RW) Binary attribute to read from and write to the device
+ configuration registers using the RapidIO maintenance
+ transactions. 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.

+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.

+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.
