This is true. However, that's just because that was what the code that I acquired from the newconfig people did. I don't think that it must be this way. : Do we really need to : support this api for common newconfig style drivers? Yes. I believe that we do. One thing that this is used for is to map things, even if they conflict. I'm sure I understand why it does that beyond checks for conflicts/valid I/O addresses in some drivers (mostly the scsi drivers). I'll have to look into what this API is supposed to do.... It is definitely heavily used (or at least used in almost all) in the few drivers that I've tried to port over.... It doesn't change the fact that bus_space_hanle_t is supposed to be an opaque type and many places in the three don't treat it as such....
