Hm. isn't there something in the specs, that a 64bit bus will be degraded to 32bit, if there are 32bit cards present? So this 64bit stuff would not be too useful in this box... > We already have generic code to do interrupt routing over bridges. > See Rev 1.14 in dec_axppci_33.c for a example on how to use it. > It's quite simple to do - getting someone with hardware to test is the > biggest challenge. > I can create you a patch if you need. I'll try to find the time to get the version (uhm, FreeBSD-cvs mirror at home, no problem so :) and screw it in. Hope to get my tests done with all puzzle parts put together. > The generic code used by axppci33 does :) Hope to be able to bring a "final version" of the patch soon. ...Michael
