Details
TC lists the Thread Context (TC) of the physical core running the vpe running this logical processor of the MIPS.
On MIPS with mt support in ases-implemented each physical core has 2 vpes.
A vpe could be seen as a hyperthreading core.
Additionally there are 9 TCs, which can be allocated across the two vpes each core.
A TC is a “lighter weigh" concept of multithreading, but provides an own execution environment.
The VR9 in the 7412 has 1 physical core with 2 VPEs running 2 processors:
On other VR9 models the vpe concept is enough to run 2 processors.
Adding the TC concept seems superfluous at the first view.
But this enables allocating up to 7 further TCs across both vpes without disturbing the processors.
This is likely done to run audio codecs with the dsp ases-implemented on an own TC.
Other models use a vpefw. The 7412 has an own TC based concept.

A ** in the Mod column marks info from Supportdata2 probes, which will always stay incomplete.
A - in the Mod column marks manual research, the Firmware then shows where the Object occurs, not the Relation.

Showing all models using this property. 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!
