2004-10-24Shuffle defines around so that ahc and ahd use the aic_ names thatKenneth R Westerback
come with the freebsd sources, rather than duplicating those names in the ahd_ and ahc_ namespaces. Big reduction in delta to freebsd sources, which reduces noise when updating the code. No .o differences found on i386. ok marco@.
2004-10-12Don't use BIOS configuration data when no seeprom is available. LetsKenneth R Westerback
SGI use more than 8 bit asynch transfers on built in ahc. Problem noted by pefo@. Fix found in NetBSD PR #23276 from Christopher Sekiya. ok pefo@.
2003-12-24Sync ahc with NetBSD, which was in turn updated from FreeBSD by PascalKenneth R Westerback
Renauld of Network Storage Solutions, Inc. Many fixes, wider device support. In particular, the notorious 'Target 0' problem seems to be fixed. Does *not* include any updates to isa or eisa code beyond what was necessary to compile. Known issues: 1) Tagged Queuing is probably not optimal. 2) PPR negotiation may not be fully functional. 3) No support yet for freezing devices or channels. 4) The mechanism for preventing 'A' and 'B' channel confusion during probe can fail if scsibus > 254 found. 5) Requeuing I/O's not working. A workaround will be committed almost immediately. At the moment timeouts, SCSI message rejects, aborting SCB's and trying to freeze a device may cause incomplete i/o's to be reported as complete. 6) Verbosity and probe messages need work. 7) Last disk on bus seems to go through an extra re-negotiation. 8) >16 devices on an adapter will trigger the usual problems of total openings exceeding available SCB's under heavy load. Tested by deraadt@, beck@, miod@, naddy@, drahn@, marc@ amoung others. ok deraadt@.
