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.
- Don't _ever_ do DMA for less than 512 bytes on the Falcon
- Fix bug in autosense-handling. Now asks for the correct number of bytes.
Now it won't read ghost bytes on the tape anymore.
- Add missing braces as suggested by Matthias Pfaller
- Make it possible to debug requests on a specified number of targets
- Add debug option to show only transaction with error code != 0
the previous version. The machine dependent part contains the configuration
for both the TT and FALCON. The configuration files have been changed to
select SCSI-support for either TT, Falcon or both.
The configuration file for the Atari-Falcon will only get _really_ usefull
when the Falcon video part is finished.
