If that was indeed David's position at the time, I think it's changed. All of bus.h as well as enough of the Bus DMA stuff to do page based bounce buffers has already been implemented and is available in the CAM SCSI layer snapshots.

They aren't really CAM specific. > cjs > Curt Sampson cjs@portal.ca Info at http://www.portal.ca/ > Internet Portal Services, Inc.
