From the keyboard of Arjan Knepper: > Any idea how much effort is needed when porting a LINUX driver to > FreeBSD? IMO, a Linux driver can be used as the docs you usually don't get from the manufacturer, we now have a case where even the Linux driver does not give all the needed information necessary to get a stable FreeBSD driver. You then have to write a new driver unless you like a GPL'd one. Even then, you will have to rewrite much of the code to adjust for another driver interface, kernel routines and the general idea of how a driver has to be written and to look like. When the driver is written, you'll need access to two sides of the PRI either as a simulator or as a real line from a carrier to debug and test the driver and to put it under (heavy) load. This is the real expensive part of the task. And this is the reason why finishing such a driver is more a task for someone doing this as payed work for someone with a commercial background (which has also the advantage of perhaps getting the real docs more easily under an NDA). hellmuth -- Hellmuth Michaelis Tel +49 40 55 97 47-70 HCS Hanseatischer Computerservice GmbH Fax +49 40 55 97 47-77 Oldesloer Strasse 97-99 Mail hm [at] hcs.de D-22457 Hamburg WWW http://www.hcs.de To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isdn" in the body of the message
