All three SCSI connectors may be used simultaneously without 131 SCSI "stub" effects. 132 1332. Version History 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. 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 introduced in 6.2.29 that 163 could cause a lock order reversal between the io_request_lock 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. 186 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 Put a .conf file in the /etc/modprobe.d directory 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 omitted 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 omitted 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. 309 ----------------------------------------------------------------- 310 311 Example: 312 'options aic7xxx aic7xxx=verbose,no_probe,tag_info:{{},{,,10}},seltime:1' 313 enables verbose logging, Disable EISA/VLB probing, 314 and set tag depth on Controller 1/Target 2 to 10 tags. 315 3164.
