We exclude it when suggesting drivers, but include it when looking for unbound devices or producing a full dump of .Pa linker.hints . This can be confusing. .Pp Some modules are hard links in .Pa /boot/kernel and will be reported twice. .Pp The PNP string's attributes are evaluated once per PNP entry on that bus rather than once. .Pp -The term PNP is overloaded in FreeBSD. +The term PNP is overloaded in +.Fx . It means, generically, the identifying data the bus provides about a device. While this include old ISA PNP identifiers, it also includes the logical equivalent in USB, PCI, and others. .Pp Many drivers currently lack proper PNP table decorations and need to be updated.
