ncrsc
— NCR 53c710
SCSI I/O Processor
ncrsc0 at pcctwo? ipl 2
The ncrsc
driver provides an abstraction
layer between the SCSI hardware fitted to Motorola MVME167 and MVME177
single board computers (NCR73C710), and the machine independent SCSI drivers
described in
scsibus(4).
In addition to sending the required SCSI commands to target
devices on the SCSI bus, the ncrsc
driver deals with
DMA, device interrupts, sync/async negotiation and target
disconnects/reconnects.
Too many to mention.
The current ncrsc
driver should be
obsoleted and replaced with a machine independent version.
