Command tagging is 60supported for all (in fact, 61.Tn FibreChannel 62requires tagging). Fabric support is enabled by default (but may 63be contingent upon the correct firmware being loaded). 64.Sh FIRMWARE 65Firmware is now available if the 66.Xr ispfw 4 67module is loaded during bootstrap (q.v.). 68.Pp 69It is very strongly recommended that you use the firmware available 70from 71.Xr ispfw 4 72as it is the most likely to have been tested with this driver. 73.Sh HARDWARE 74Supported cards include: 75.Pp 76.Bl -tag -width xxxxxx -offset indent 77.It ISP1000 78SBus Fast Wide, Ultra Fast Wide cards, Single Ended or Differential 79cards. 80.It PTI SBS440 81Performance Technology ISP1000 variants. 82.It ISP1020 83Qlogic 1020 Fast Wide and Differential Fast Wide PCI cards. 84.It ISP1040 85Qlogic 1040 Ultra Wide and Differential Ultra Wide PCI cards. 86.It PTI SBS450 87Performance Technology ISP1040 variants. 88.It Qlogic 1240 89Qlogic 1240 Dual Bus Ultra Wide and Differential Ultra Wide PCI 90cards. 91.It Qlogic 1080 92Qlogic 1280 LVD Ultra2 Wide PCI cards. 93.It Qlogic 1280 94Qlogic 1280 Dual Bus LVD Ultra2 Wide PCI cards. 95.It Qlogic 12160 96Qlogic 12160 Dual Bus LVD Ultra3 Wide PCI cards. 97.It Qlogic 2100 98Qlogic 2100 and 2100A Copper and Optical Fibre Channel Arbitrated 99Loop 100.It Qlogic 2102 101Qlogic Dual Loop 2100A Optical Fibre Channel Arbitrated Loop PCI 102cards. 103.It Qlogic 2200 104Qlogic 2200 Copper and Optical Fibre Channel Arbitrated Loop PCI 105cards. 106.It Qlogic 2202 107Qlogic 2200 Dual Bus Optical Fibre Channel Arbitrated Loop PCI 108cards. 109.It PTI SBS470 110Performance Technology ISP2100 variants. 111.It Antares P-0033 112Antares Microsystems ISP2100 variants. 113.El 114.Sh CONFIGURATION OPTIONS 115.Pp 116Target mode support may be enabled with the 117.Pp 118.Cd options ISP_TARGET_MODE 119.Pp 120option. 121.Sh BOOT OPTIONS 122The following options are switchable by setting values in the loader 123configuration file (see the 124.Xr loader 8 125manual page). They are: 126.Pp 127.Bl -tag -width "isp_no_fwload" -compact 128.It isp_disable 129A bit mask of units to skip configuration for. 130.It isp_mem_map 131A bit mask of units to use PCI Memory space instead of I/O space 132access for. 133.It isp_io_map 134A bit mask of units to use PCI I/O space instead of Memory space 135access for. 136.It isp_no_nvram 137A bit mask of units that you wish to ignore board NVRAM settings 138for. 139.It isp_nvram 140A bit mask of units that you wish to specifically use board NVRAM 141settings for. 142.It isp_fcduplex 143A bit mask of units that you wish to specifically to set into full 144duplex mode. 145.It isp_no_fcduplex 146A bit mask of units that you wish to specifically to not set into 147full duplex mode. 148.It isp_wwn 149This should be the full 64 bit World Wide Node Name you would like 150to use, overriding the value in NVRAM for the card. 151.It isp_debug 152This is a driver debug level- meaningful from 0 through 7. 153.It isp_tdebug 154This is a driver target mode debug level- meaningful from 0 through 1555. 156.El 157.Sh BUGS 158The driver currently ignores some NVRAM settings. 159.Pp 160The driver currently doesn't do error recovery for timed out commands 161very gracefully. 162.Pp 163Target mode support isn't completely debugged yet. It works reasonably 164well for Fibre Channel, somewhat well for Qlogic 1040 cards, but 165doesn't yet work for the other cards (due to last minute unnanounced 166changes in firmware interfaces). 167.Pp 168Sometimes, when booting, the driver gets stuck waiting for the 169Fibre Channel f/w to tell it that the loop port database is ready, 170or waiting for a good loop to be seen (this does not yet support 171booting without being connected to a fibre channel device). To 172unwedge the system, unplug and replug the fibre channel connection, 173or otherwise cause a LIP (Loop Initialization Primitive sequence)- 174this will kick the f/w into getting unstuck. 175.Sh SEE ALSO 176.Xr da 4 , 177.Xr intro 4 , 178.Xr sa 4 , 179.Xr scsi 4 180.Sh AUTHORS 181The 182.Nm 183driver was written by Matthew Jacob for NASA/Ames Research Center. 184
