127 1. No BIOS support
128 2. DEC21050 PCI-PCI bridge with multiple controller chips on secondary bus
129 3. DEC2115X PCI-PCI bridge with multiple controller chips on secondary bus
130 4. All three SCSI connectors may be used simultaneously without
131 SCSI "stub" effects.
133 2. Version History
135 6.2.33 - Dynamically disable PCI parity error reporting after
136 10 errors are reported to the user. These errors are
137 the result of some other device issuing PCI transactions
138 with bad parity. Once the user has been informed of the
139 problem, continuing to report the errors just degrades
140 our performance.
142 6.2.32 - Dynamically sized S/G lists to avoid SCSI malloc
143 pool fragmentation and SCSI mid-layer deadlock.
145 6.2.28 - Domain Validation Fixes
146 PCI parity error disable
147 Enhanced Memory Mapped I/O probe
149 6.2.20 - Added Domain Validation
151 3. Command Line Options
153 WARNING: ALTERING OR ADDING THESE DRIVER PARAMETERS
154 INCORRECTLY CAN RENDER YOUR SYSTEM INOPERABLE.
155 USE THEM WITH CAUTION.
157 Edit the file "modules.conf" in the directory /etc and add/edit a
158 line containing 'options aic7xxx aic7xxx=[command[,command...]]' where
159 'command' is one or more of the following:
160 -----------------------------------------------------------------
161 Option: verbose
162 Definition: enable additional informative messages during
163 driver operation.
164 Possible Values: This option is a flag
165 Default Value: disabled
166 -----------------------------------------------------------------
167 Option: debug:[value]
168 Definition: Enables various levels of debugging information
169 Possible Values: 0x0000 = no debugging, 0xffff = full debugging
170 Default Value: 0x0000
171 -----------------------------------------------------------------
172 Option: no_probe
173 Option: probe_eisa_vl
174 Definition: Do not probe for EISA/VLB controllers.
175 This is a toggle. If the driver is compiled
176 to not probe EISA/VLB controllers by default,
177 specifying "no_probe" will enable this probing.
178 If the driver is compiled to probe EISA/VLB
179 controllers by default, specifying "no_probe"
180 will disable this probing.
181 Possible Values: This option is a toggle
182 Default Value: EISA/VLB probing is disabled by default.
183 -----------------------------------------------------------------
184 Option: pci_parity
185 Definition: Toggles the detection of PCI parity errors.
186 On many motherboards with VIA chipsets,
187 PCI parity is not generated correctly on the
188 PCI bus. It is impossible for the hardware to
189 differentiate between these "spurious" parity
190 errors and real parity errors. The symptom of
191 this problem is a stream of the message:
192 "scsi0: Data Parity Error Detected during address or write data phase"
193 output by the driver.
194 Possible Values: This option is a toggle
195 Default Value: PCI Parity Error reporting is disabled
196 -----------------------------------------------------------------
197 Option: no_reset
198 Definition: Do not reset the bus during the initial probe
199 phase
200 Possible Values: This option is a flag
201 Default Value: disabled
202 -----------------------------------------------------------------
203 Option: extended
204 Definition: Force extended translation on the controller
205 Possible Values: This option is a flag
206 Default Value: disabled
207 -----------------------------------------------------------------
208 Option: periodic_otag
209 Definition: Send an ordered tag periodically to prevent
210 tag starvation. Needed for some older devices
211 Possible Values: This option is a flag
212 Default Value: disabled
213 -----------------------------------------------------------------
214 Option: reverse_scan
215 Definition: Probe the scsi bus in reverse order, starting
216 with target 15
217 Possible Values: This option is a flag
218 Default Value: disabled
219 -----------------------------------------------------------------
220 Option: global_tag_depth:[value]
221 Definition: Global tag depth for all targets on all busses.
222 This option sets the default tag depth which
223 may be selectively overridden vi the tag_info
224 option.
225 Possible Values: 1 - 253
226 Default Value: 32
227 -----------------------------------------------------------------
228 Option: tag_info:{{value[,value...]}[,{value[,value...]}...]}
229 Definition: Set the per-target tagged queue depth on a
230 per controller basis. Both controllers and targets
231 may be ommitted indicating that they should retain
232 the default tag depth.
233 Examples: tag_info:{{16,32,32,64,8,8,,32,32,32,32,32,32,32,32,32}
234 On Controller 0
235 specifies a tag depth of 16 for target 0
236 specifies a tag depth of 64 for target 3
237 specifies a tag depth of 8 for targets 4 and 5
238 leaves target 6 at the default
239 specifies a tag depth of 32 for targets 1,2,7-15
240 All other targets retain the default depth.
242 tag_info:{{},{32,,32}}
243 On Controller 1
244 specifies a tag depth of 32 for targets 0 and 2
245 All other targets retain the default depth.
247 Possible Values: 1 - 253
248 Default Value: 32
249 -----------------------------------------------------------------
250 Option: seltime:[value]
251 Definition: Specifies the selection timeout value
252 Possible Values: 0 = 256ms, 1 = 128ms, 2 = 64ms, 3 = 32ms
253 Default Value: 0
254 -----------------------------------------------------------------
255 Option: dv: {value[,value...]}
256 Definition: Set Domain Validation Policy on a per-controller basis.
257 Controllers may be ommitted indicating that
258 they should retain the default read streaming setting.
259 Example: dv:{-1,0,,1,1,0}
260 On Controller 0 leave DV at its default setting.
261 On Controller 1 disable DV.
262 Skip configuration on Controller 2.
263 On Controllers 3 and 4 enable DV.
264 On Controller 5 disable DV.
266 Possible Values: < 0 Use setting from serial EEPROM.
267 0 Disable DV
268 > 0 Enable DV
270 Default Value: SCSI-Select setting on controllers with a SCSI Select
271 option for DV. Otherwise, on for controllers supporting
272 U160 speeds and off for all other controller types.
273 -----------------------------------------------------------------
275 Example:
276 'options aic7xxx aic7xxx=verbose,no_probe,tag_info:{{},{,,10}},seltime:1"
277 enables verbose logging, Disable EISA/VLB probing,
278 and set tag depth on Controller 1/Target 2 to 10 tags.
