0140
0141 2. Version History
0142 ==================
0143
0144 * 7.0 (4th August, 2005)
0145 - Updated driver to use SCSI transport class infrastructure
0146 - Upported sequencer and core fixes from last adaptec released
0147 version of the driver.
0148
0149 * 6.2.36 (June 3rd, 2003)
0150 - Correct code that disables PCI parity error checking.
0151 - Correct and simplify handling of the ignore wide residue
0152 message. The previous code would fail to report a residual
0153 if the transaction data length was even and we received
0154 an IWR message.
0155 - Add support for the 2.5.X EISA framework.
0156 - Update for change in 2.5.X SCSI proc FS interface.
0157 - Correct Domain Validation command-line option parsing.
0158 - When negotiation async via an 8bit WDTR message, send
0159 an SDTR with an offset of 0 to be sure the target
0160 knows we are async. This works around a firmware defect
0161 in the Quantum Atlas 10K.
0162 - Clear PCI error state during driver attach so that we
0163 don't disable memory mapped I/O due to a stray write
0164 by some other driver probe that occurred before we
0165 claimed the controller.
0166
0167 * 6.2.35 (May 14th, 2003)
0168 - Fix a few GCC 3.3 compiler warnings.
0169 - Correct operation on EISA Twin Channel controller.
0170 - Add support for 2.5.X's scsi_report_device_reset().
0171
0172 * 6.2.34 (May 5th, 2003)
0173 - Fix locking regression introduced in 6.2.29 that
0174 could cause a lock order reversal between the io_request_lock
0175 and our per-softc lock. This was only possible on RH9,
0176 SuSE, and kernel.org 2.4.X kernels.
0177
0178 * 6.2.33 (April 30th, 2003)
0179 - Dynamically disable PCI parity error reporting after
0180 10 errors are reported to the user. These errors are
0181 the result of some other device issuing PCI transactions
0182 with bad parity. Once the user has been informed of the
0183 problem, continuing to report the errors just degrades
0184 our performance.
0185
0186 * 6.2.32 (March 28th, 2003)
0187 - Dynamically sized S/G lists to avoid SCSI malloc
0188 pool fragmentation and SCSI mid-layer deadlock.
0189
0190 * 6.2.28 (January 20th, 2003)
0191 - Domain Validation Fixes
0192 - Add ability to disable PCI parity error checking.
0193 - Enhanced Memory Mapped I/O probe
0194
0195 * 6.2.20 (November 7th, 2002)
0196 - Added Domain Validation.

0198 3. Command Line Options
0199 =======================
0200
0201
0202 .. Warning::
0203
0204 ALTERING OR ADDING THESE DRIVER PARAMETERS
0205 INCORRECTLY CAN RENDER YOUR SYSTEM INOPERABLE.
0206 USE THEM WITH CAUTION.
0207
0208 Put a .conf file in the /etc/modprobe.d directory and add/edit a
0209 line containing ``options aic7xxx aic7xxx=[command[,command...]]`` where
0210 ``command`` is one or more of the following:
0211
0212 verbose
0213
0214 :Definition: enable additional informative messages during driver operation.
0215 :Possible Values: This option is a flag
0216 :Default Value: disabled
0217
0218
0219 debug:[value]
0220
0221 :Definition: Enables various levels of debugging information
0222 :Possible Values: 0x0000 = no debugging, 0xffff = full debugging
0223 :Default Value: 0x0000
0224
0225 no_probe
0226
0227 probe_eisa_vl
0228
0229 :Definition: Do not probe for EISA/VLB controllers.
0230 This is a toggle. If the driver is compiled
0231 to not probe EISA/VLB controllers by default,
0232 specifying "no_probe" will enable this probing.
0233 If the driver is compiled to probe EISA/VLB
0234 controllers by default, specifying "no_probe"
0235 will disable this probing.
0236
0237 :Possible Values: This option is a toggle
0238 :Default Value: EISA/VLB probing is disabled by default.
0239
0240 pci_parity
0241
0242 :Definition: Toggles the detection of PCI parity errors.
0243 On many motherboards with VIA chipsets,
0244 PCI parity is not generated correctly on the
0245 PCI bus. It is impossible for the hardware to
0246 differentiate between these "spurious" parity
0247 errors and real parity errors. The symptom of
0248 this problem is a stream of the message::
0249
0250 "scsi0: Data Parity Error Detected during address or write data phase"
0251
0252 output by the driver.
0253
0254 :Possible Values: This option is a toggle
0255 :Default Value: PCI Parity Error reporting is disabled
0256
0257 no_reset
0258
0259 :Definition: Do not reset the bus during the initial probe
0260 phase
0261
0262 :Possible Values: This option is a flag
0263 :Default Value: disabled
0264
0265 extended
0266
0267 :Definition: Force extended translation on the controller
0268 :Possible Values: This option is a flag
0269 :Default Value: disabled
0270
0271 periodic_otag
0272
0273 :Definition: Send an ordered tag periodically to prevent
0274 tag starvation. Needed for some older devices
0275
0276 :Possible Values: This option is a flag
0277 :Default Value: disabled
0278
0279 reverse_scan
0280
0281 :Definition: Probe the scsi bus in reverse order, starting
0282 with target 15
0283
0284 :Possible Values: This option is a flag
0285 :Default Value: disabled
0286
0287 global_tag_depth:[value]
0288
0289 :Definition: Global tag depth for all targets on all busses.
0290 This option sets the default tag depth which
0291 may be selectively overridden vi the tag_info
0292 option.
0293
0294 :Possible Values: 1 - 253
0295 :Default Value: 32
0296
0297 tag_info:{{value[,value...]}[,{value[,value...]}...]}
0298
0299 :Definition: Set the per-target tagged queue depth on a
0300 per controller basis. Both controllers and targets
0301 may be omitted indicating that they should retain
0302 the default tag depth.
0303
0304 :Possible Values: 1 - 253
0305 :Default Value: 32
0306
0307 Examples:
0308
0309 ::
0310
0311 tag_info:{{16,32,32,64,8,8,,32,32,32,32,32,32,32,32,32}
0312
0313 On Controller 0:
0314
0315 - specifies a tag depth of 16 for target 0
0316 - specifies a tag depth of 64 for target 3
0317 - specifies a tag depth of 8 for targets 4 and 5
0318 - leaves target 6 at the default
0319 - specifies a tag depth of 32 for targets 1,2,7-15
0320 - All other targets retain the default depth.
0321
0322 ::
0323
0324 tag_info:{{},{32,,32}}
0325
0326 On Controller 1:
0327
0328 - specifies a tag depth of 32 for targets 0 and 2
0329 - All other targets retain the default depth.
0330
0331 seltime:[value]
0332
0333 :Definition: Specifies the selection timeout value
0334 :Possible Values: 0 = 256ms, 1 = 128ms, 2 = 64ms, 3 = 32ms
0335 :Default Value: 0
0336
0337 dv: {value[,value...]}
0338
0339 :Definition: Set Domain Validation Policy on a per-controller basis.
0340 Controllers may be omitted indicating that
0341 they should retain the default read streaming setting.
0342
0343 :Possible Values:
0344
0345 ==== ===============================
0346 < 0 Use setting from serial EEPROM.
0347 0 Disable DV
0348 > 0 Enable DV
0349 ==== ===============================
0350
0351
0352 :Default Value: SCSI-Select setting on controllers with a SCSI Select
0353 option for DV. Otherwise, on for controllers supporting
0354 U160 speeds and off for all other controller types.
0355
0356 Example:
0357
0358 ::
0359
0360 dv:{-1,0,,1,1,0}
0361
0362 - On Controller 0 leave DV at its default setting.
0363 - On Controller 1 disable DV.
0364 - Skip configuration on Controller 2.
