130 4. All three SCSI connectors may be used simultaneously without
131 SCSI "stub" effects.
132
1332. Version History
134 6.2.36 (June 3rd, 2003)
135 - Correct code that disables PCI parity error checking.
136 - Correct and simplify handling of the ignore wide residue
137 message. The previous code would fail to report a residual
138 if the transaction data length was even and we received
139 an IWR message.
140 - Add support for the 2.5.X EISA framework.
141 - Update for change in 2.5.X SCSI proc FS interface.
142 - Correct Domain Validation command-line option parsing.
143 - When negotiation async via an 8bit WDTR message, send
144 an SDTR with an offset of 0 to be sure the target
145 knows we are async. This works around a firmware defect
146 in the Quantum Atlas 10K.
147 - Clear PCI error state during driver attach so that we
148 don't disable memory mapped I/O due to a stray write
149 by some other driver probe that occurred before we
150 claimed the controller.
151
152 6.2.35 (May 14th, 2003)
153 - Fix a few GCC 3.3 compiler warnings.
154 - Correct operation on EISA Twin Channel controller.
155 - Add support for 2.5.X's scsi_report_device_reset().
156
157 6.2.34 (May 5th, 2003)
158 - Fix locking regression instroduced in 6.2.29 that
159 could cuase a lock order reversal between the io_request_lock
160 and our per-softc lock. This was only possible on RH9,
161 SuSE, and kernel.org 2.4.X kernels.
162
163 6.2.33 (April 30th, 2003)
164 - Dynamically disable PCI parity error reporting after
165 10 errors are reported to the user. These errors are
166 the result of some other device issuing PCI transactions
167 with bad parity. Once the user has been informed of the
168 problem, continuing to report the errors just degrades
169 our performance.
170
171 6.2.32 (March 28th, 2003)
172 - Dynamically sized S/G lists to avoid SCSI malloc
173 pool fragmentation and SCSI mid-layer deadlock.
174
175 6.2.28 (January 20th, 2003)
176 - Domain Validation Fixes
177 - Add ability to disable PCI parity error checking.
178 - Enhanced Memory Mapped I/O probe
179
180 6.2.20 (November 7th, 2002)
181 - Added Domain Validation.

1833. Command Line Options
184
185 WARNING: ALTERING OR ADDING THESE DRIVER PARAMETERS
186 INCORRECTLY CAN RENDER YOUR SYSTEM INOPERABLE.
187 USE THEM WITH CAUTION.
188
189 Edit the file "modprobe.conf" in the directory /etc and add/edit a
190 line containing 'options aic7xxx aic7xxx=[command[,command...]]' where
191 'command' is one or more of the following:
192 -----------------------------------------------------------------
193 Option: verbose
194 Definition: enable additional informative messages during
195 driver operation.
196 Possible Values: This option is a flag
197 Default Value: disabled
198 -----------------------------------------------------------------
199 Option: debug:[value]
200 Definition: Enables various levels of debugging information
201 Possible Values: 0x0000 = no debugging, 0xffff = full debugging
202 Default Value: 0x0000
203 -----------------------------------------------------------------
204 Option: no_probe
205 Option: probe_eisa_vl
206 Definition: Do not probe for EISA/VLB controllers.
207 This is a toggle. If the driver is compiled
208 to not probe EISA/VLB controllers by default,
209 specifying "no_probe" will enable this probing.
210 If the driver is compiled to probe EISA/VLB
211 controllers by default, specifying "no_probe"
212 will disable this probing.
213 Possible Values: This option is a toggle
214 Default Value: EISA/VLB probing is disabled by default.
215 -----------------------------------------------------------------
216 Option: pci_parity
217 Definition: Toggles the detection of PCI parity errors.
218 On many motherboards with VIA chipsets,
219 PCI parity is not generated correctly on the
220 PCI bus. It is impossible for the hardware to
221 differentiate between these "spurious" parity
222 errors and real parity errors. The symptom of
223 this problem is a stream of the message:
224 "scsi0: Data Parity Error Detected during address or write data phase"
225 output by the driver.
226 Possible Values: This option is a toggle
227 Default Value: PCI Parity Error reporting is disabled
228 -----------------------------------------------------------------
229 Option: no_reset
230 Definition: Do not reset the bus during the initial probe
231 phase
232 Possible Values: This option is a flag
233 Default Value: disabled
234 -----------------------------------------------------------------
235 Option: extended
236 Definition: Force extended translation on the controller
237 Possible Values: This option is a flag
238 Default Value: disabled
239 -----------------------------------------------------------------
240 Option: periodic_otag
241 Definition: Send an ordered tag periodically to prevent
242 tag starvation. Needed for some older devices
243 Possible Values: This option is a flag
244 Default Value: disabled
245 -----------------------------------------------------------------
246 Option: reverse_scan
247 Definition: Probe the scsi bus in reverse order, starting
248 with target 15
249 Possible Values: This option is a flag
250 Default Value: disabled
251 -----------------------------------------------------------------
252 Option: global_tag_depth:[value]
253 Definition: Global tag depth for all targets on all busses.
254 This option sets the default tag depth which
255 may be selectively overridden vi the tag_info
256 option.
257 Possible Values: 1 - 253
258 Default Value: 32
259 -----------------------------------------------------------------
260 Option: tag_info:{{value[,value...]}[,{value[,value...]}...]}
261 Definition: Set the per-target tagged queue depth on a
262 per controller basis. Both controllers and targets
263 may be ommitted indicating that they should retain
264 the default tag depth.
265 Examples: tag_info:{{16,32,32,64,8,8,,32,32,32,32,32,32,32,32,32}
266 On Controller 0
267 specifies a tag depth of 16 for target 0
268 specifies a tag depth of 64 for target 3
269 specifies a tag depth of 8 for targets 4 and 5
270 leaves target 6 at the default
271 specifies a tag depth of 32 for targets 1,2,7-15
272 All other targets retain the default depth.
273
274 tag_info:{{},{32,,32}}
275 On Controller 1
276 specifies a tag depth of 32 for targets 0 and 2
277 All other targets retain the default depth.
278
279 Possible Values: 1 - 253
280 Default Value: 32
281 -----------------------------------------------------------------
282 Option: seltime:[value]
283 Definition: Specifies the selection timeout value
284 Possible Values: 0 = 256ms, 1 = 128ms, 2 = 64ms, 3 = 32ms
285 Default Value: 0
286 -----------------------------------------------------------------
287 Option: dv: {value[,value...]}
288 Definition: Set Domain Validation Policy on a per-controller basis.
289 Controllers may be ommitted indicating that
290 they should retain the default read streaming setting.
291 Example: dv:{-1,0,,1,1,0}
292 On Controller 0 leave DV at its default setting.
293 On Controller 1 disable DV.
294 Skip configuration on Controller 2.
295 On Controllers 3 and 4 enable DV.
296 On Controller 5 disable DV.
297
298 Possible Values: < 0 Use setting from serial EEPROM.
299 0 Disable DV
300 > 0 Enable DV
301
302 Default Value: SCSI-Select setting on controllers with a SCSI Select
303 option for DV. Otherwise, on for controllers supporting
304 U160 speeds and off for all other controller types.
305 -----------------------------------------------------------------
306
307 Example:
308 'options aic7xxx aic7xxx=verbose,no_probe,tag_info:{{},{,,10}},seltime:1"
309 enables verbose logging, Disable EISA/VLB probing,
310 and set tag depth on Controller 1/Target 2 to 10 tags.
