isa_intr_{,dis}establish()) here. Make this file safely includable by
<dev/isa/isavar.h> and by all of the places in the i386 that are currently
including it, which means multiple inclusion protection and a few
otherwise-extraneous 'forward' structure declarations. isa_intr_establish()
and isa_intr_disestablish() now take as their first argument a
machine-dependent cookie of type isa_chipset_tag_t, which is also defined
here.
- split softc size and match/attach out from cfdriver into
a new struct cfattach.
- new "attach" directive for files.*. May specify the name of
the cfattach structure, so that devices may be easily attached
to parents with different autoconfiguration semantics.
which represents the "keyboard controller". Give "pc" and "vt" drivers
the "pckbd" attribute. In pcattach() (pccons and pcvt), attach children
of the keyboard controller.
retrying the operation. Fixes disk_unbusy() imbalance and really seems
like the right thing to do in case it was the seek that failed. Takes
care of PR #1985. Patch from John F. Woods <jfw@jfwhome.funhouse.com>
- New metrics handling. Metrics are now kept in the new
`struct disk'. Busy time is now stored as a timeval, and
transfer count in bytes.
- Storage for disklabels is now dynamically allocated, so that
the size of the disk structure is not machine-dependent.
- Several new functions for attaching and detaching disks, and
handling metrics calculation.
Old-style instrumentation is still supported in drivers that did it before.
However, old-style instrumentation is being deprecated, and will go away
once the userland utilities are updated for the new framework.

page.
at halt time, especially if a floppy was mounted. Added a shutdown hook
to turn off the motor. Per a request by mycroft, the cookie from the hook
is saved in a new member I added to the fd_softc structure.
