1332. Version History
James Bottomley79778a22005-08-04 17:33:22 -0500[diff] [blame]134 7.0 (4th August, 2005)
135 - Updated driver to use SCSI transport class infrastructure
136 - Upported sequencer and core fixes from last adaptec released
137 version of the driver.
Linus Torvalds1da177e2005-04-16 15:20:36 -0700[diff] [blame]138 6.2.36 (June 3rd, 2003)
139 - Correct code that disables PCI parity error checking.
140 - Correct and simplify handling of the ignore wide residue
141 message. The previous code would fail to report a residual
142 if the transaction data length was even and we received
143 an IWR message.
144 - Add support for the 2.5.X EISA framework.
145 - Update for change in 2.5.X SCSI proc FS interface.
146 - Correct Domain Validation command-line option parsing.
147 - When negotiation async via an 8bit WDTR message, send
148 an SDTR with an offset of 0 to be sure the target
149 knows we are async. This works around a firmware defect
150 in the Quantum Atlas 10K.
151 - Clear PCI error state during driver attach so that we
152 don't disable memory mapped I/O due to a stray write
153 by some other driver probe that occurred before we
154 claimed the controller.
155
156 6.2.35 (May 14th, 2003)
157 - Fix a few GCC 3.3 compiler warnings.
158 - Correct operation on EISA Twin Channel controller.
159 - Add support for 2.5.X's scsi_report_device_reset().
160
161 6.2.34 (May 5th, 2003)
162 - Fix locking regression instroduced in 6.2.29 that
Matt LaPlante6c28f2c2006-10-03 22:46:31 +0200[diff] [blame]163 could cause a lock order reversal between the io_request_lock
Linus Torvalds1da177e2005-04-16 15:20:36 -0700[diff] [blame]164 and our per-softc lock. This was only possible on RH9,
165 SuSE, and kernel.org 2.4.X kernels.
166
167 6.2.33 (April 30th, 2003)
168 - Dynamically disable PCI parity error reporting after
169 10 errors are reported to the user. These errors are
170 the result of some other device issuing PCI transactions
171 with bad parity. Once the user has been informed of the
172 problem, continuing to report the errors just degrades
173 our performance.
174
175 6.2.32 (March 28th, 2003)
176 - Dynamically sized S/G lists to avoid SCSI malloc
177 pool fragmentation and SCSI mid-layer deadlock.
178
179 6.2.28 (January 20th, 2003)
180 - Domain Validation Fixes
181 - Add ability to disable PCI parity error checking.
182 - Enhanced Memory Mapped I/O probe
183
184 6.2.20 (November 7th, 2002)
185 - Added Domain Validation.

1873. Command Line Options
188
189 WARNING: ALTERING OR ADDING THESE DRIVER PARAMETERS
190 INCORRECTLY CAN RENDER YOUR SYSTEM INOPERABLE.
191 USE THEM WITH CAUTION.
192
193 Edit the file "modprobe.conf" in the directory /etc and add/edit a
194 line containing 'options aic7xxx aic7xxx=[command[,command...]]' where
195 'command' is one or more of the following:
196 -----------------------------------------------------------------
197 Option: verbose
198 Definition: enable additional informative messages during
199 driver operation.
200 Possible Values: This option is a flag
201 Default Value: disabled
202 -----------------------------------------------------------------
203 Option: debug:[value]
204 Definition: Enables various levels of debugging information
205 Possible Values: 0x0000 = no debugging, 0xffff = full debugging
206 Default Value: 0x0000
207 -----------------------------------------------------------------
208 Option: no_probe
209 Option: probe_eisa_vl
210 Definition: Do not probe for EISA/VLB controllers.
211 This is a toggle. If the driver is compiled
212 to not probe EISA/VLB controllers by default,
213 specifying "no_probe" will enable this probing.
214 If the driver is compiled to probe EISA/VLB
215 controllers by default, specifying "no_probe"
216 will disable this probing.
217 Possible Values: This option is a toggle
218 Default Value: EISA/VLB probing is disabled by default.
219 -----------------------------------------------------------------
220 Option: pci_parity
221 Definition: Toggles the detection of PCI parity errors.
222 On many motherboards with VIA chipsets,
223 PCI parity is not generated correctly on the
224 PCI bus. It is impossible for the hardware to
225 differentiate between these "spurious" parity
226 errors and real parity errors. The symptom of
227 this problem is a stream of the message:
228 "scsi0: Data Parity Error Detected during address or write data phase"
229 output by the driver.
230 Possible Values: This option is a toggle
231 Default Value: PCI Parity Error reporting is disabled
232 -----------------------------------------------------------------
233 Option: no_reset
234 Definition: Do not reset the bus during the initial probe
235 phase
236 Possible Values: This option is a flag
237 Default Value: disabled
238 -----------------------------------------------------------------
239 Option: extended
240 Definition: Force extended translation on the controller
241 Possible Values: This option is a flag
242 Default Value: disabled
243 -----------------------------------------------------------------
244 Option: periodic_otag
245 Definition: Send an ordered tag periodically to prevent
246 tag starvation. Needed for some older devices
247 Possible Values: This option is a flag
248 Default Value: disabled
249 -----------------------------------------------------------------
250 Option: reverse_scan
251 Definition: Probe the scsi bus in reverse order, starting
252 with target 15
253 Possible Values: This option is a flag
254 Default Value: disabled
255 -----------------------------------------------------------------
256 Option: global_tag_depth:[value]
257 Definition: Global tag depth for all targets on all busses.
258 This option sets the default tag depth which
259 may be selectively overridden vi the tag_info
260 option.
261 Possible Values: 1 - 253
262 Default Value: 32
263 -----------------------------------------------------------------
264 Option: tag_info:{{value[,value...]}[,{value[,value...]}...]}
265 Definition: Set the per-target tagged queue depth on a
266 per controller basis. Both controllers and targets
267 may be ommitted indicating that they should retain
268 the default tag depth.
269 Examples: tag_info:{{16,32,32,64,8,8,,32,32,32,32,32,32,32,32,32}
270 On Controller 0
271 specifies a tag depth of 16 for target 0
272 specifies a tag depth of 64 for target 3
273 specifies a tag depth of 8 for targets 4 and 5
274 leaves target 6 at the default
275 specifies a tag depth of 32 for targets 1,2,7-15
276 All other targets retain the default depth.
277
278 tag_info:{{},{32,,32}}
279 On Controller 1
280 specifies a tag depth of 32 for targets 0 and 2
281 All other targets retain the default depth.
282
283 Possible Values: 1 - 253
284 Default Value: 32
285 -----------------------------------------------------------------
286 Option: seltime:[value]
287 Definition: Specifies the selection timeout value
288 Possible Values: 0 = 256ms, 1 = 128ms, 2 = 64ms, 3 = 32ms
289 Default Value: 0
290 -----------------------------------------------------------------
291 Option: dv: {value[,value...]}
292 Definition: Set Domain Validation Policy on a per-controller basis.
293 Controllers may be ommitted indicating that
294 they should retain the default read streaming setting.
295 Example: dv:{-1,0,,1,1,0}
296 On Controller 0 leave DV at its default setting.
297 On Controller 1 disable DV.
298 Skip configuration on Controller 2.
299 On Controllers 3 and 4 enable DV.
300 On Controller 5 disable DV.
301
302 Possible Values: < 0 Use setting from serial EEPROM.
303 0 Disable DV
304 > 0 Enable DV
305
306 Default Value: SCSI-Select setting on controllers with a SCSI Select
307 option for DV. Otherwise, on for controllers supporting
308 U160 speeds and off for all other controller types.

Linus Torvalds1da177e2005-04-16 15:20:36 -0700[diff] [blame]313 enables verbose logging, Disable EISA/VLB probing,
