There are some ABI documents that, while they don't generate any warnings, they have issues when parsed by get_abi.pl script on its output result. Address them, in order to provide a clean output.

What: /sys/class/rapidio_port
|
|
Description:
|
|
On-chip RapidIO controllers and PCIe-to-RapidIO bridges
|
|
(referenced as "Master Port" or "mport") are presented in sysfs
|
|
as the special class of devices: "rapidio_port".
|
|
The /sys/class/rapidio_port subdirectory contains individual
|
|
subdirectories named as "rapidioN" where N = mport ID registered
|
|
with RapidIO subsystem.
|
|
|
|
NOTE: An mport ID is not a RapidIO destination ID assigned to a
|
|
given local mport device.

(RO) reports RapidIO common transport system size:

0 = small (8-bit destination ID, max. 256 devices),

|
|
|
1 = large (16-bit destination ID, max. 65536 devices).

Description:
|
|
|
|
(RO) reports RapidIO destination ID assigned to the given
|
|
RapidIO mport device. If value 0xFFFFFFFF is returned this means
|
|
that no valid destination ID have been assigned to the mport
|
|
(yet). Normally, before enumeration/discovery have been executed
|
|
only fabric enumerating mports have a valid destination ID
|
|
assigned to them using "hdid=..." rapidio module parameter.
|
|
|
|
After enumeration or discovery was performed for a given mport device,
|
|
the corresponding subdirectory will also contain subdirectories for each
|
|
child RapidIO device connected to the mport.
|
|
|
|
The example below shows mport device subdirectory with several child RapidIO
|
|
devices attached to it::

|
|
