Version History + 7.0 (4th August, 2005) + - Updated driver to use SCSI transport class infrastructure + - Upported sequencer and core fixes from last adaptec released + version of the driver. + 6.2.36 (June 3rd, 2003) + - Correct code that disables PCI parity error checking. + - Correct and simplify handling of the ignore wide residue + message. The previous code would fail to report a residual + if the transaction data length was even and we received + an IWR message. + - Add support for the 2.5.X EISA framework. + - Update for change in 2.5.X SCSI proc FS interface. + - Correct Domain Validation command-line option parsing. + - When negotiation async via an 8bit WDTR message, send + an SDTR with an offset of 0 to be sure the target + knows we are async. This works around a firmware defect + in the Quantum Atlas 10K. + - Clear PCI error state during driver attach so that we + don't disable memory mapped I/O due to a stray write + by some other driver probe that occurred before we + claimed the controller. + + 6.2.35 (May 14th, 2003) + - Fix a few GCC 3.3 compiler warnings. + - Correct operation on EISA Twin Channel controller. + - Add support for 2.5.X's scsi_report_device_reset(). + + 6.2.34 (May 5th, 2003) + - Fix locking regression introduced in 6.2.29 that + could cause a lock order reversal between the io_request_lock + and our per-softc lock. This was only possible on RH9, + SuSE, and kernel.org 2.4.X kernels. + + 6.2.33 (April 30th, 2003) + - Dynamically disable PCI parity error reporting after + 10 errors are reported to the user. These errors are + the result of some other device issuing PCI transactions + with bad parity. Once the user has been informed of the + problem, continuing to report the errors just degrades + our performance. + + 6.2.32 (March 28th, 2003) + - Dynamically sized S/G lists to avoid SCSI malloc + pool fragmentation and SCSI mid-layer deadlock. + + 6.2.28 (January 20th, 2003) + - Domain Validation Fixes + - Add ability to disable PCI parity error checking. + - Enhanced Memory Mapped I/O probe + + 6.2.20 (November 7th, 2002) + - Added Domain Validation. + +3.
