"device ispfw" 46.Ed 47.Pp 48Alternatively, to load the driver as a 49module at boot time, place the following lines in 50.Xr loader.conf 5 : 51.Bd -literal -offset indent 52isp_load="YES"

70.Tn SCSI 71or 72.Tn FibreChannel 73devices. 74.Pp 75SCSI features include support for Ultra SCSI and wide mode transactions 76for 77.Tn SCSI , 78Ultra2 LVD (for the ISP1080 and ISP1280), and Ultra3 LVD (for the 79ISP12160). 80.Pp 81Fibre Channel support uses FCP SCSI profile for 82.Tn FibreChannel . 83and utilizes Class 3 and Class 2 connections (Qlogic 2100 is Class 843 only, minor patches to the Qlogic 2200 to force Class 2 mode). 85Support is available for Public and Private loops, and for 86point-to-point connections (Qlogic 2200 only). 87The newer 2-Gigabit cards (2300, 2312, 2322) and 4-Gigabit (2422, 2432) 88are also supported. 89Command tagging is 90supported for all (in fact, 91.Tn FibreChannel 92requires tagging). 93Fabric support is enabled by default for other than 2100 cards. 94Fabric 95support for 2100 cards has been so problematic and these cards are so 96old now that it is just not worth your time to try it. 97.Sh FIRMWARE 98Firmware is available if the appropriate firmware module 99is loaded during bootstrap (see 100.Xr ispfw 4 ) . 101.Pp 102It is 103.Em strongly 104recommended that you use the firmware supplied with 105.Dx 106as it is the most likely to have been tested with this driver. 107.Sh HARDWARE 108Cards supported by the 109.Nm 110driver include: 111.Bl -tag -width xxxxxx -offset indent 112.It ISP1000 113SBus Fast Wide, Ultra Fast

158.Pp 159option. 160.Sh BOOT OPTIONS 161The following options are switchable by setting values in 162.Pa /boot/device.hints . 163.Pp 164They are: 165.Bl -tag -width indent 166.It Va hint.isp.0.disable 167A hint value to disable driver in kernel. 168.It Va hint.isp.0.fwload_disable 169A hint value to disable loading of firmware 170.Xr ispfw 4 . 171.It Va hint.isp.0.prefer_memmap 172A hint value to use PCI memory space instead of I/O space 173access for. 174.It Va hint.isp.0.prefer_iomap 175A hint value to use PCI I/O space instead of Memory space 176access for. 177.It Va hint.isp.0.ignore_nvram 178A hint value to ignore board NVRAM settings for. 179Otherwise use NVRAM settings. 180.It Va hint.isp.0.fullduplex 181A hint value to set full duplex mode. 182.It Va hint.isp.0.topology 183A hint value to select topology of connection. 184Supported values are: 185.Pp 186.Bl -tag -width ".Li lport-only" -compact 187.It Li lport 188Prefer loopback and fallback to point to point. 189.It Li nport 190Prefer point to point and fallback to loopback. 191.It Li lport-only 192Loopback only. 193.It Li nport-only 194Point to point only. 195.El 196.It Va hint.isp.0.portwwn 197This should be the full 64 bit World Wide Port Name you would like 198to use, overriding the value in NVRAM for the card. 199.It Va hint.isp.0.nodewwn 200This should be the full 64 bit World Wide Node Name you would like 201to use, overriding the value in NVRAM for the card. 202.It Va hint.isp.0.iid 203A hint to override or set the Initiator ID or Loop ID. 204For Fibre Channel 205cards in Local Loop topologies it is 206.Ar strongly 207recommended that you set this value to non-zero. 208.It Va hint.isp.0.role 209A hint to define default role for isp instance (target, initiator, both). 210.It Va hint.isp.0.debug 211A hint value for a driver debug level (see the file 212.Pa /usr/src/sys/dev/isp/ispvar.h 213for the values. 214.El 215.Pp 216By default, the driver will use MSI if it is supported. 217This behavior can be turned off by setting the following tunable: 218.Bd -literal -offset indent 219hw.isp.msi.enable=0 220.Ed 221.Sh SYSCTL OPTIONS 222.Bl -tag -width indent 223.It Va dev.isp.N.loop_down_limit 224This value says how long to wait in seconds after loop has gone down before 225giving up and expiring all of the devices that were visible. 226The default is 300 seconds (5 minutes). 227A separate (nonadjustable) timeout is used when 228booting to not stop booting on lack of FC connectivity. 229.It Va dev.isp.N.gone_device_time 230This value says how long to wait for devices to reappear if they (temporarily) 231disappear due to loop or fabric events. 232While this timeout is running, I/O 233to those devices will simply be held. 234.It Va dev.isp.N.wwnn 235This is the readonly World Wide Node Name value for this port. 236.It Va dev.isp.N.wwpn 237This is the readonly World Wide Port Name value for this port. 238.El 239.Sh SEE ALSO

251.Sh BUGS 252The driver currently ignores some NVRAM settings. 253.Pp 254Target mode support is not completely reliable yet. 255It works reasonably 256well for Fibre Channel, somewhat well for Qlogic 1040 cards, but 257does not yet work for the other cards (due to last minute unannounced 258changes in firmware interfaces). 259
