From 4f844a2461025f3d1f55c557d2d2fbbe12ce5f5d Mon Sep 17 00:00:00 2001 From: Kenneth R Westerback Date: Wed, 24 Dec 2003 23:27:56 +0000 Subject: Sync ahc with NetBSD, which was in turn updated from FreeBSD by Pascal 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.
