I don't think that I'll have anything workable in the next month... as next monday is the first day of classes, and I've been working this week... so I haven't made any progress yet... > Several concepts have been discussed, with > the "extent registration" of NetBSD being > mentioned very often. > > My concept is quite different, in that I'd > rather have a functional interface, which > works on bus-dependent data structures that > have to exist anyway, while the extent data > does exist independently of device data. have you actually looked at the extent stuff from NetBSD?? you still have to write the wrappers around the extent to use the resources, it's just that it provides a way to do mapping of sections of units... > I have outlined this before ... > > > that 'ISA/Exclusive' interrupts are not allowed to be registered as > > 'shared' resources, I think there are potential problems with the > > Well, ISA interrupts should be registered in > a way that guarantees they are not shared. I agree.. but this should be on a bus dependant side... and with the new isa_device stuff I have invisioned.... we will be able to do more dynamic sharing of irqs... suchs as marking irqs as only used when device is active... so you can share irqs between devices... i.e. the common com1/com3 problem... ttyl.. -- John-Mark Gurney Modem/FAX: +1 541 683 6954 Cu Networking Live in Peace, destroy Micro$oft, support free software, run FreeBSD
