Hi, Erik- I used some of your concepts from the 1020 driver in the conjoint ISP 2X00/1XXX driver that's FreeBSD/NetBSD (and there's a linux version too...)- thinks for the neat idea about quickly figuring out the number of in/out mailbox registers to use for a particular command. If this is the 53c974, this really could be a conjoint ESP100 - 53c974 - FAS266 driver, couldn't it? Basically this is chip core is plunked right into the middle of the 10X0 which then wraps a risc processor aroundit. I'd love to see a newer driver using this (I did the SunOS/Solaris esp driver)- particularly if it had a micro state machine to (quickly) manage all the 7-10 interrupts/command that you have to do... I haven't the bandwidth to really drive any of this, but I'd be glad to provide testing and even equipment resources (maybe you can slogin into feral- maybe we can make this work on FreeBSD/alpha as a good proof of concept)...? > Hello, > > I have an interest in seeing the amd0 driver being supported by the new > CAM SCSI subsystem.
