multi-channel driver), or to SCSI_CHANNEL_ONLY_ONE if a
single-channel driver.
(2) use scsiprint() rather than a locally-defined autoconfig print
function, and kill any locally-defined print function.
a char *, because that's what was really intended, and because
if the print function modifies the string, various things could become
unhappy (so the string should _not_ be modified).
we managed to kill the following SCSI-driver bugs for the Falcon:
- The Byte_Count_zero bit of the falcon DMA controller does not always
tell the truth! This caused the SCSI-driver to choke on devices that
disconnected in the middle of a DMA-transfer (mostly removables).
- Printing debug info about the 5380 on the Falcon is *only* permitted
when DMA is not active.
- Some functions forgot to remove possibly pending sofware interrupts
- Some debug options didn't allow debugging a single target while they
could easily be made to do so. This is fixed.
of a lot of instability problems on the Falcon. I also enabled DMA on
interrupt basis for the Falcon.
- Try to handle targets that request too much data more sanely.
- Some fixups for strict prototypes + -Wall
Thanks to Markus Kilbinger for providing the debugging support.
- 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.

- 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.
For usage and architectural details, see the forthcoming disk(9) manual
page.
