src/sys/arch/mac68k/dev: sbc.c
Log Message:
Use smaller size when sending PDMA data, and check that the next block can
be sent before sending it.
This fixes PDMA support (which previously has been flakey at best).
These changes provide maximum performance and importantly reliablity.
The lack of support for the PDMA intr should now be revisited on the PowerBook
5xx series (Unfortunately I don't have the hw to test with).
These changes have been tested on emulated (PiSCSI/BlueSCSI) and real hw.
