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.

configuration registers using the RapidIO maintenance

"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:
|
|
(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.
