Details

ioports provides the I/O port regions in use. While being present nearly everywhere it's often empty or very limited.

Supportdata2 includes ioports in the Meminfo section since sd2-09.
In Supportdata-Probes it was never included (up to fw 7.39).

Excerpt from the proc(5) man page:

/proc/ioports

       This is a list of currently registered Input-Output port
       regions that are in use.

Showing all models using this object. Click any column header (click-wait-click) to sort the list by the respective data.
The (main/scrpn/boot/arm/prx/atom) label in the Model column shows which CPU is meant for models with multiple Linux instances.
Note that this list comes from Supportdata2 probes, which can have arbitrary settings and come from different firmware versions.
It doesn't say much if a model is not listed here. It may be a missing supportdata2 file or just a disabled feature.

Help Supportdata2

The data in this article is incomplete since it was manually collected using the Supportdata2 project.

Unlike the Supportdata-Probes which have been collected for years Supportdata2 is brand new and only has a few probes.
If you have access to a shell then please help to extend the Supportdata2 collection to improve this data.

It's easy and it's done in minutes. Please send created data as an Email attachment to the address listed here. Thanks!
