1) Pass address and ipl locators at attachment;
2) Remove hack which made the internal HP-IB controller
look like a DIO device.
The hack to allow the nhpib driver to support internal and DIO
controllers appears to be a leftover from 4.3BD where it was not
possible to have a driver attach to different busses. NetBSD has
supported bus-dependent attachments for a long time.
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
resource allocation.
- Insertion and removal of callouts is constant time, important as
this facility is used quite a lot in the kernel.
The old timeout()/untimeout() API has been removed from the kernel.
to a softc, rather than a unit number. Add a "dq_softc" member
to struct devqueue; this is a temporary measure until the
dma/controller/device callback spaghetti is untangled.
YAY! No more need for dcafastservice!
HIL: squish instances of "(void) splhil()" and "(void) spl0();".
be done. Set up a structure filled with function pointers in the
controller-specific probe routines, and jump through them, instead of
if()'ing our way though each operation.
Be a little more discriptive; print out the controller type found
during the probe in a way that's somewhat meaningful.
