37 .Nd Qlogic based SCSI and FibreChannel SCSI Host Adapters
39 To compile this driver into the kernel,
40 place the following lines in your
41 kernel configuration file:
42 .Bd -ragged -offset indent
48 Alternatively, to load the driver as a
49 module at boot time, place the following lines in
51 .Bd -literal -offset indent
54 isp_1040_it_load="YES"
56 isp_1080_it_load="YES"
58 isp_12160_it_load="YES"
64 isp_2400_multi_load="YES"
66 isp_2500_multi_load="YES"
69 This driver provides access to
75 SCSI features include support for Ultra SCSI and wide mode transactions
78 Ultra2 LVD (for the ISP1080 and ISP1280), and Ultra3 LVD (for the
81 Fibre Channel support uses FCP SCSI profile for
83 and utilizes Class 3 and Class 2 connections (Qlogic 2100 is Class
84 3 only, minor patches to the Qlogic 2200 to force Class 2 mode).
85 Support is available for Public and Private loops, and for
86 point-to-point connections (Qlogic 2200 only).
87 The newer 2-Gigabit cards (2300, 2312, 2322) and 4-Gigabit (2422, 2432)
90 supported for all (in fact,
93 Fabric support is enabled by default for other than 2100 cards.
95 support for 2100 cards has been so problematic and these cards are so
96 old now that it is just not worth your time to try it.
98 Firmware is available if the appropriate firmware module
99 is loaded during bootstrap (see
104 recommended that you use the firmware supplied with
106 as it is the most likely to have been tested with this driver.

154 .Sh CONFIGURATION OPTIONS
155 Target mode support may be enabled with the
157 .Cd options ISP_TARGET_MODE
161 The following options are switchable by setting values in
162 .Pa /boot/device.hints .
165 .Bl -tag -width indent
166 .It Va hint.isp.0.disable
167 A hint value to disable driver in kernel.
168 .It Va hint.isp.0.fwload_disable
169 A hint value to disable loading of firmware
171 .It Va hint.isp.0.prefer_memmap
172 A hint value to use PCI memory space instead of I/O space
174 .It Va hint.isp.0.prefer_iomap
175 A hint value to use PCI I/O space instead of Memory space
177 .It Va hint.isp.0.ignore_nvram
178 A hint value to ignore board NVRAM settings for.
179 Otherwise use NVRAM settings.
180 .It Va hint.isp.0.fullduplex
181 A hint value to set full duplex mode.
182 .It Va hint.isp.0.topology
183 A hint value to select topology of connection.
184 Supported values are:
186 .Bl -tag -width ".Li lport-only" -compact
188 Prefer loopback and fallback to point to point.
190 Prefer point to point and fallback to loopback.
196 .It Va hint.isp.0.portwwn
197 This should be the full 64 bit World Wide Port Name you would like
198 to use, overriding the value in NVRAM for the card.
199 .It Va hint.isp.0.nodewwn
200 This should be the full 64 bit World Wide Node Name you would like
201 to use, overriding the value in NVRAM for the card.
202 .It Va hint.isp.0.iid
203 A hint to override or set the Initiator ID or Loop ID.
205 cards in Local Loop topologies it is
207 recommended that you set this value to non-zero.
208 .It Va hint.isp.0.role
209 A hint to define default role for isp instance (target, initiator, both).
210 .It Va hint.isp.0.debug
211 A hint value for a driver debug level (see the file
212 .Pa /usr/src/sys/dev/isp/ispvar.h
216 By default, the driver will use MSI if it is supported.
217 This behavior can be turned off by setting the following tunable:
218 .Bd -literal -offset indent
222 .Bl -tag -width indent
223 .It Va dev.isp.N.loop_down_limit
224 This value says how long to wait in seconds after loop has gone down before
225 giving up and expiring all of the devices that were visible.
226 The default is 300 seconds (5 minutes).
227 A separate (nonadjustable) timeout is used when
228 booting to not stop booting on lack of FC connectivity.
229 .It Va dev.isp.N.gone_device_time
230 This value says how long to wait for devices to reappear if they (temporarily)
231 disappear due to loop or fabric events.
232 While this timeout is running, I/O
233 to those devices will simply be held.
234 .It Va dev.isp.N.wwnn
235 This is the readonly World Wide Node Name value for this port.
236 .It Va dev.isp.N.wwpn
237 This is the readonly World Wide Port Name value for this port.
248 driver was written by
252 at NASA/Ames Research Center.
254 The driver currently ignores some NVRAM settings.
256 Target mode support is not completely reliable yet.
258 well for Fibre Channel, somewhat well for Qlogic 1040 cards, but
259 does not yet work for the other cards (due to last minute unannounced
260 changes in firmware interfaces).
