Version History142==================143 144 * 7.0 (4th August, 2005)145 - Updated driver to use SCSI transport class infrastructure146 - Upported sequencer and core fixes from last adaptec released147 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 residue152 message. The previous code would fail to report a residual153 if the transaction data length was even and we received154 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, send159 an SDTR with an offset of 0 to be sure the target160 knows we are async. This works around a firmware defect161 in the Quantum Atlas 10K.162 - Clear PCI error state during driver attach so that we163 don't disable memory mapped I/O due to a stray write164 by some other driver probe that occurred before we165 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 that174 could cause a lock order reversal between the io_request_lock175 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 after180 10 errors are reported to the user. These errors are181 the result of some other device issuing PCI transactions182 with bad parity. Once the user has been informed of the183 problem, continuing to report the errors just degrades184 our performance.185 186 * 6.2.32 (March 28th, 2003)187 - Dynamically sized S/G lists to avoid SCSI malloc188 pool fragmentation and SCSI mid-layer deadlock.189 190 * 6.2.28 (January 20th, 2003)191 - Domain Validation Fixes192 - Add ability to disable PCI parity error checking.193 - Enhanced Memory Mapped I/O probe194 195 * 6.2.20 (November 7th, 2002)196 - Added Domain Validation.197 1983.
