As the guy who have been secretly architecting the current stuff from right back then, I can confidently say that to get our "removable device" support into a decent shape will take some work. The Nomads work are pretty focused on pccards, but in the same framework we should look at CardBus, docking stations, hot-plug PCI and goddamnit: PlugAndPray since this is the mechanism that is supposed to make support for all these things managable. As usual, if you start to fiddle this stuff, you hit your head on the usual suspects: 1. Improved support for loadable devices. 2. Real mode BIOS calls. 3. A Registry. 4. (optional:) pageable kernel modules. So the current state of the Nomads code is understandable and I belive pretty unavoidable, considering the lack of a concerted effort on the above necessary technologies... I think the best path is to leave the Nomads in charge of the actual drivers for the devices, and try to find some person and some means for working on the above 4 issues. -- Poul-Henning Kamp | phk@FreeBSD.ORG FreeBSD Core-team. http://www.freebsd.org/~phk | phk@login.dknet.dk Private mailbox. whois: [PHK] | phk@tfs.com TRW Financial Systems, Inc. Power and ignorance is a disgusting cocktail.
