Hi. I'm interested in detecting if thunderbolt is present on a running system. I need this as a part of certification testing so that the test operator can be asked to do some thunderbolt-specific tasks. I talked to some of the maintainers and from what I've learned there are two thunderbolt drivers, one for apple and one for everything else. The one for apple has the nice property of being able to statically detect that the hardware is present. The one for everything else, which I'm more interested in as I'm not certifying apple hardware, apparently does not and there is no way to detect that a machine has a thunderbolt port unless something is physically plugged into that port. So I'd like to ask more broadly, is the statement above accurate? Can the presence of a thunderbolt port be detected from a running system reliably?
