All three SCSI connectors may be used simultaneously without 139 SCSI "stub" effects. 140 1412. Version History 142================== 143 144 * 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. 148 149 * 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 154 an IWR message. 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. 166 167 * 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(). 171 172 * 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. 177 178 * 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 184 our performance. 185 186 * 6.2.32 (March 28th, 2003) 187 - Dynamically sized S/G lists to avoid SCSI malloc 188 pool fragmentation and SCSI mid-layer deadlock. 189 190 * 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 194 195 * 6.2.20 (November 7th, 2002) 196 - Added Domain Validation. 197 1983.
