Hi folks, just subscribed to the list, so I might have missed something .... <snip>
Constructing unique names that are human readable, stable, unique and fit to 31 characters reserved for the purpose is not thought to be possible: device bus string that would be in some cases enough to uniquely identify a device any be longer than that. On hot-pluggable busses e.g. a serial number is needed.
Dont we have any chance of lifting that restriction ? From a userland PoV, I'd really like to see them via path names (and actually access them directly via their own files)
The structure of the properties tree can be non-trivial. This RFC defines a text representation format of the tree to facilitate discussing and documenting the tree structure separately from its binary representation used in IOCTL calls. The terms are used elsewhere in the document.
Does it have to be an IOTCTL ? IOCTL have the unpleasant side effect, that they're hard to transport via network filesystems (in the end, would need special protocol extensions for each single one - assuming we can *safely* detect, which IOCTL really was called) Instead I'd prefer some pure filesystem-based approach - like @Plan9 or sysfs. cu -- Enrico Weigelt, metux IT consult +49-151-27565287 MELAG Medizintechnik oHG Sitz Berlin Registergericht AG Charlottenburg HRA 21333 B Wichtiger Hinweis: Diese Nachricht kann vertrauliche oder nur für einen begrenzten Personenkreis bestimmte Informationen enthalten.
