 137    3. DEC2115X PCI-PCI bridge with multiple controller chips on secondary bus

 141 2. 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.

 230                  This is a toggle.  If the driver is compiled
 231                  to not probe EISA/VLB controllers by default,
 232                  specifying "no_probe" will enable this probing.
 233                  If the driver is compiled to probe EISA/VLB
 234                  controllers by default, specifying "no_probe"

 240 pci_parity
 241
 242     :Definition: Toggles the detection of PCI parity errors.
 243                  On many motherboards with VIA chipsets,
 244                  PCI parity is not generated correctly on the
 245                  PCI bus.  It is impossible for the hardware to
 246                  differentiate between these "spurious" parity
 247                  errors and real parity errors.  The symptom of
 248                  this problem is a stream of the message::
 249
 250                     "scsi0:     Data Parity Error Detected during address or write data phase"
 251
 252                  output by the driver.
