WDSC(4)             NetBSD/sgimips Kernel Interfaces Manual            WDSC(4)


NAME

     wdsc -- Western Digital WD33c93 SCSI Bus Interface Controller


SYNOPSIS

     wdsc* at hpc? offset ?


DESCRIPTION

     The wdsc driver provides an abstraction layer between the SCSI hardware
     found in multitudinous SGI machines (including Personal Iris series,
     Indigo, Indy, Challenge S, Indigo2, and Challenge M) 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 wdsc driver deals with DMA, device interrupts,
     sync/async negotiation, and target disconnects/reconnects.


SEE ALSO

     hpc(4), scsibus(4)


HISTORY

     Wayne Knowles ported the sgimips incarnation of the wdsc driver from the
     amiga and atari ports.  It first appeared in NetBSD 1.6.
