Author: ken Date: Wed Aug 2 20:24:28 2017 New Revision: 321945 URL: https://svnweb.freebsd.org/changeset/base/321945 Log: MFC r321622, r321623: ------------------------------------------------------------------------ r321622 | ken | 2017-07-27 09:33:57 -0600 (Thu, 27 Jul 2017) | 44 lines Fix probing FC targets with hard addressing turned on. This largely reverts FreeBSD SVN change 289937 from October 25th, 2015. The intent of that change was to keep loop IDs persistent across chip reinits. The problem is that the change turned on the PREVLOOP / PREV_ADDRESS bit (bit 7 in Firmware Options 2), which tells the Qlogic chip to not participate in the loop if it can't get the requested loop address. It also turned off soft addressing on 2400 (4Gb) and newer controllers. The isp(4) driver defaults to loop address 0, and the tape drives I have tested default to loop address 0 if hard addressing is turned on. So when hard loop addressing is turned on on the drive, the isp(4) driver just refuses to participate in the loop. The solution is to largely revert that change. I left some elements in place that are related to virtual ports, since they were new. This does work with IBM tape drives with hard and soft addressing turned on. I have tested it with 4Gb, 8Gb, and 16Gb controllers. sys/dev/isp.c: Largely revert FreeBSD SVN change 289937. I left the ispmbox.h changes in place. Don't use the PREV_ADDRESS bit on initialization. It tells the chip to not participate if it can't get the requested loop ID. Do use soft addressing on 2400 and newer chips. Use hard addressing when the user has requested a specific initiator ID. (hint.isp.X.iid=N in /boot/loader.conf) Leave some of the virtual port options from that change in place, but don't turn on the PREV_ADDRESS bit.
