XFMstatus: 0610 From: Simon Shapiro <Shimon@i-Connect.Net> To: freebsd-scsi@freebsd.org Subject: Some SCSI Questions... Hi Y'all, Me again, with more questions: 1. I want to port cdwrite 2.0 from Linux (and get rid but have no clue what the userland API to the generic device (userland SCB) is. Can someone please help me with: a. What is the /dev entry? b. What options in config do I need to turn on? c. (At least) header file pathname to API 2. In writing a SCSI device driver, how does one differentiate a device reset from bus reset from HBA reset? I can guess, that an HBA reset may come as a device reset flag in the xs struct, destined for the HBA's target ID. But on which bus? We have an HBA which has three busses. We can have multiple of these HBA's in the system. We set the HBA softc struct as an array (linked list, actually) of softc structures. In each softc we have an array of scsi_link structures to manage that. But question #2 is not answered by that, to my understanding. Thanx!
