136 2. DEC21050 PCI-PCI bridge with multiple controller chips on secondary bus
137 3. DEC2115X PCI-PCI bridge with multiple controller chips on secondary bus
138 4. All three SCSI connectors may be used simultaneously without
144 * 7.0 (4th August, 2005)
145 - Updated driver to use SCSI transport class infrastructure
146 - Upported sequencer and core fixes from last adaptec released
147 version of the driver.
149 * 6.2.36 (June 3rd, 2003)
150 - Correct code that disables PCI parity error checking.
151 - Correct and simplify handling of the ignore wide residue
152 message. The previous code would fail to report a residual
153 if the transaction data length was even and we received
155 - Add support for the 2.5.X EISA framework.
156 - Update for change in 2.5.X SCSI proc FS interface.
157 - Correct Domain Validation command-line option parsing.
158 - When negotiation async via an 8bit WDTR message, send
159 an SDTR with an offset of 0 to be sure the target
160 knows we are async. This works around a firmware defect
161 in the Quantum Atlas 10K.
162 - Clear PCI error state during driver attach so that we
163 don't disable memory mapped I/O due to a stray write
164 by some other driver probe that occurred before we
165 claimed the controller.
167 * 6.2.35 (May 14th, 2003)
168 - Fix a few GCC 3.3 compiler warnings.
169 - Correct operation on EISA Twin Channel controller.
170 - Add support for 2.5.X's scsi_report_device_reset().
172 * 6.2.34 (May 5th, 2003)
173 - Fix locking regression introduced in 6.2.29 that
174 could cause a lock order reversal between the io_request_lock
175 and our per-softc lock. This was only possible on RH9,
176 SuSE, and kernel.org 2.4.X kernels.
178 * 6.2.33 (April 30th, 2003)
179 - Dynamically disable PCI parity error reporting after
180 10 errors are reported to the user. These errors are
181 the result of some other device issuing PCI transactions
182 with bad parity. Once the user has been informed of the
183 problem, continuing to report the errors just degrades
186 * 6.2.32 (March 28th, 2003)
187 - Dynamically sized S/G lists to avoid SCSI malloc
188 pool fragmentation and SCSI mid-layer deadlock.
190 * 6.2.28 (January 20th, 2003)
191 - Domain Validation Fixes
192 - Add ability to disable PCI parity error checking.
193 - Enhanced Memory Mapped I/O probe
195 * 6.2.20 (November 7th, 2002)
196 - Added Domain Validation.
198 3. Command Line Options
199 =======================
204 ALTERING OR ADDING THESE DRIVER PARAMETERS
205 INCORRECTLY CAN RENDER YOUR SYSTEM INOPERABLE.
206 USE THEM WITH CAUTION.
208 Put a .conf file in the /etc/modprobe.d directory and add/edit a
209 line containing ``options aic7xxx aic7xxx=[command[,command...]]`` where
210 ``command`` is one or more of the following:
214 :Definition: enable additional informative messages during driver operation.
215 :Possible Values: This option is a flag
216 :Default Value: disabled
221 :Definition: Enables various levels of debugging information
222 :Possible Values: 0x0000 = no debugging, 0xffff = full debugging
223 :Default Value: 0x0000
229 :Definition: Do not probe for EISA/VLB controllers.
230 This is a toggle. If the driver is compiled
231 to not probe EISA/VLB controllers by default,
232 specifying "no_probe" will enable this probing.
233 If the driver is compiled to probe EISA/VLB
234 controllers by default, specifying "no_probe"
235 will disable this probing.
237 :Possible Values: This option is a toggle
238 :Default Value: EISA/VLB probing is disabled by default.
242 :Definition: Toggles the detection of PCI parity errors.
243 On many motherboards with VIA chipsets,
244 PCI parity is not generated correctly on the
245 PCI bus. It is impossible for the hardware to
246 differentiate between these "spurious" parity
247 errors and real parity errors. The symptom of
248 this problem is a stream of the message::
250 "scsi0: Data Parity Error Detected during address or write data phase"
252 output by the driver.
254 :Possible Values: This option is a toggle
255 :Default Value: PCI Parity Error reporting is disabled
259 :Definition: Do not reset the bus during the initial probe
262 :Possible Values: This option is a flag
263 :Default Value: disabled
267 :Definition: Force extended translation on the controller
268 :Possible Values: This option is a flag
269 :Default Value: disabled
273 :Definition: Send an ordered tag periodically to prevent
274 tag starvation. Needed for some older devices
276 :Possible Values: This option is a flag
277 :Default Value: disabled
281 :Definition: Probe the scsi bus in reverse order, starting
284 :Possible Values: This option is a flag
285 :Default Value: disabled
287 global_tag_depth:[value]
289 :Definition: Global tag depth for all targets on all busses.
290 This option sets the default tag depth which
291 may be selectively overridden vi the tag_info
294 :Possible Values: 1 - 253
297 tag_info:{{value[,value...]}[,{value[,value...]}...]}
299 :Definition: Set the per-target tagged queue depth on a
300 per controller basis. Both controllers and targets
301 may be omitted indicating that they should retain
302 the default tag depth.
304 :Possible Values: 1 - 253
311 tag_info:{{16,32,32,64,8,8,,32,32,32,32,32,32,32,32,32}
315 - specifies a tag depth of 16 for target 0
316 - specifies a tag depth of 64 for target 3
317 - specifies a tag depth of 8 for targets 4 and 5
318 - leaves target 6 at the default
319 - specifies a tag depth of 32 for targets 1,2,7-15
320 - All other targets retain the default depth.
324 tag_info:{{},{32,,32}}
328 - specifies a tag depth of 32 for targets 0 and 2
329 - All other targets retain the default depth.
333 :Definition: Specifies the selection timeout value
334 :Possible Values: 0 = 256ms, 1 = 128ms, 2 = 64ms, 3 = 32ms
337 dv: {value[,value...]}
339 :Definition: Set Domain Validation Policy on a per-controller basis.
340 Controllers may be omitted indicating that
341 they should retain the default read streaming setting.
345 ==== ===============================
346 < 0 Use setting from serial EEPROM.
349 ==== ===============================
352 :Default Value: SCSI-Select setting on controllers with a SCSI Select
353 option for DV. Otherwise, on for controllers supporting
354 U160 speeds and off for all other controller types.
362 - On Controller 0 leave DV at its default setting.
363 - On Controller 1 disable DV.
364 - Skip configuration on Controller 2.
365 - On Controllers 3 and 4 enable DV.
366 - On Controller 5 disable DV.
370 options aic7xxx aic7xxx=verbose,no_probe,tag_info:{{},{,,10}},seltime:1
372 enables verbose logging, Disable EISA/VLB probing,
373 and set tag depth on Controller 1/Target 2 to 10 tags.
