Regards Oliver BoF on USB and Hotplugging Participants: Brad Hards(USB), Tim Jansen(KDE), Oliver Neukum(USB), one unnamed and largely silent GNOME coder and several other interested participants. Unfortunately nobody of XFree was present. Topics: - definitions - delivering events - information needed by user space - device numbers, names and associated stuff Definitions: I remember nothing noteworthy Delivering events: General consensus was that there's nothing wrong in that regard. The KDE and GNOME people would be quite happy with the hotplugging scripts writing all information they have to a named pipe or something similar. It seems that nobody really cares much about the exact mechanism. A suggestion was made that a demon should be introduced. That was not discussed fully. Later discussion with the X people which are to be continued shows that the X people would want to introduce an X extension for device discovery and notification issues. Information needed by user space: Items of consensus: - physical path and all available device ids must be delivered - groupings of devices must be delivered - most crucial item: user space needs a mapping between physical and logical device - user space wants a device _name_ - driverfs and the input layer must be documented A partial solution to the issues was found. There needs to be a second kind of hotplugging event that is generated upon "associating" a device to a driver Device numbers, names and associated stuff Items of consensus: - device numbers are a bad idea - there needs to be some "dynamic element" There was absolute disagreement over devfs. Oppinions ranged from "devfs must go away" to "hotplugging without devfs is obviously stupid" ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Linux-hotplug-devel mailing list http://linux-hotplug.sourceforge.net Linux-hotplug-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linux-hotplug-devel
