  722. Version History
  73==================
  74
  75
  76 * 3.0    (December 1st, 2005)
  77        - Updated driver to use SCSI transport class infrastructure
  78        - Upported sequencer and core fixes from adaptec released
  79          version 2.0.15 of the driver.
  80
  81 * 1.3.11 (July 11, 2003)
  82        - Fix several deadlock issues.
  83        - Add 29320ALP and 39320B Id's.
  84
  85 * 1.3.10 (June 3rd, 2003)
  86        - Align the SCB_TAG field on a 16byte boundary.  This avoids
  87          SCB corruption on some PCI-33 busses.
  88        - Correct non-zero luns on Rev B. hardware.
  89        - Update for change in 2.5.X SCSI proc FS interface.
  90        - When negotiation async via an 8bit WDTR message, send
  91          an SDTR with an offset of 0 to be sure the target
  92          knows we are async.  This works around a firmware defect
  93          in the Quantum Atlas 10K.
  94        - Implement controller suspend and resume.
  95        - Clear PCI error state during driver attach so that we
  96          don't disable memory mapped I/O due to a stray write
  97          by some other driver probe that occurred before we
  98          claimed the controller.
  99
 100 * 1.3.9 (May 22nd, 2003)
 101        - Fix compiler errors.
 102        - Remove S/G splitting for segments that cross a 4GB boundary.
 103          This is guaranteed not to happen in Linux.
 104        - Add support for scsi_report_device_reset() found in
 105          2.5.X kernels.
 106        - Add 7901B support.
 107        - Simplify handling of the packetized lun Rev A workaround.
 108        - Correct and simplify handling of the ignore wide residue
 109          message.  The previous code would fail to report a residual
 110          if the transaction data length was even and we received
 111          an IWR message.
 112
 113 * 1.3.8 (April 29th, 2003)
 114        - Fix types accessed via the command line interface code.
 115        - Perform a few firmware optimizations.
 116        - Fix "Unexpected PKT busfree" errors.
 117        - Use a sequencer interrupt to notify the host of
 118          commands with bad status.  We defer the notification
 119          until there are no outstanding selections to ensure
 120          that the host is interrupted for as short a time as
 121          possible.
 122        - Remove pre-2.2.X support.
 123        - Add support for new 2.5.X interrupt API.
 124        - Correct big-endian architecture support.
 125
 126 * 1.3.7 (April 16th, 2003)
 127        - Use del_timer_sync() to ensure that no timeouts
 128          are pending during controller shutdown.
 129        - For pre-2.5.X kernels, carefully adjust our segment
 130          list size to avoid SCSI malloc pool fragmentation.
 131        - Cleanup channel display in our /proc output.
 132        - Workaround duplicate device entries in the mid-layer
 133          device list during add-single-device.
 134
 135 * 1.3.6 (March 28th, 2003)
 136        - Correct a double free in the Domain Validation code.
 137        - Correct a reference to free'ed memory during controller
 138          shutdown.
 139        - Reset the bus on an SE->LVD change.  This is required
 140          to reset our transceivers.
 141
 142 * 1.3.5 (March 24th, 2003)
 143        - Fix a few register window mode bugs.
 144        - Include read streaming in the PPR flags we display in
 145          diagnostics as well as /proc.
 146        - Add PCI hot plug support for 2.5.X kernels.
 147        - Correct default precompensation value for RevA hardware.
 148        - Fix Domain Validation thread shutdown.
 149        - Add a firmware workaround to make the LED blink
 150          brighter during packetized operations on the H2A4.
 151        - Correct /proc display of user read streaming settings.
 152        - Simplify driver locking by releasing the io_request_lock
 153          upon driver entry from the mid-layer.
 154        - Cleanup command line parsing and move much of this code
 155          to aiclib.
 156
 157 * 1.3.4 (February 28th, 2003)
 158        - Correct a race condition in our error recovery handler.
 159        - Allow Test Unit Ready commands to take a full 5 seconds
 160          during Domain Validation.
 161
 162 * 1.3.2 (February 19th, 2003)
 163        - Correct a Rev B. regression due to the GEM318
 164          compatibility fix included in 1.3.1.
 165
 166 * 1.3.1 (February 11th, 2003)
 167        - Add support for the 39320A.
 168        - Improve recovery for certain PCI-X errors.
 169        - Fix handling of LQ/DATA/LQ/DATA for the
 170          same write transaction that can occur without
 171          interveining training.
 172        - Correct compatibility issues with the GEM318
 173          enclosure services device.
 174        - Correct data corruption issue that occurred under
 175          high tag depth write loads.
 176        - Adapt to a change in the 2.5.X daemonize() API.
 177        - Correct a "Missing case in ahd_handle_scsiint" panic.
 178
 179 * 1.3.0 (January 21st, 2003)
 180        - Full regression testing for all U320 products completed.
 181        - Added abort and target/lun reset error recovery handler and
 182          interrupt coalescing.
 183
 184 * 1.2.0 (November 14th, 2002)
 185        - Added support for Domain Validation
 186        - Add support for the Hewlett-Packard version of the 39320D
 187          and AIC-7902 adapters.
 188
 189        Support for previous adapters has not been fully tested and should
 190        only be used at the customer's own risk.
 191
 192 * 1.1.1 (September 24th, 2002)

 4734. Additional Notes
 474===================
 475
 4764.1. Known/Unresolved or FYI Issues
 477-----------------------------------
 478
 479        * Under SuSE Linux Enterprise 7, the driver may fail to operate
 480          correctly due to a problem with PCI interrupt routing in the
 481          Linux kernel.  Please contact SuSE for an updated Linux
 482          kernel.
 483
 4844.2. Third-Party Compatibility Issues
 485-------------------------------------
 486
 487        * Adaptec only supports Ultra320 hard drives running
 488          the latest firmware available. Please check with
 489          your hard drive manufacturer to ensure you have the
 490          latest version.
 491
 4924.3. Operating System or Technology Limitations
 493-----------------------------------------------
 494
 495        * PCI Hot Plug is untested and may cause the operating system
 496          to stop responding.
 497        * Luns that are not numbered contiguously starting with 0 might not
 498          be automatically probed during system startup.  This is a limitation
 499          of the OS.  Please contact your Linux vendor for instructions on
 500          manually probing non-contiguous luns.
 501        * Using the Driver Update Disk version of this package during OS
 502          installation under RedHat might result in two versions of this
 503          driver being installed into the system module directory.  This
 504          might cause problems with the /sbin/mkinitrd program and/or
 505          other RPM packages that try to install system modules.  The best
 506          way to correct this once the system is running is to install
 507          the latest RPM package version of this driver, available from
 508          http://www.adaptec.com.
