642. Version History
65
66   3.0	  (December 1st, 2005)
67	- Updated driver to use SCSI transport class infrastructure
68	- Upported sequencer and core fixes from adaptec released
69	  version 2.0.15 of the driver.
70
71   1.3.11 (July 11, 2003)
72        - Fix several deadlock issues.
73        - Add 29320ALP and 39320B Id's.
74
75   1.3.10 (June 3rd, 2003)
76        - Align the SCB_TAG field on a 16byte boundary.  This avoids
77          SCB corruption on some PCI-33 busses.
78        - Correct non-zero luns on Rev B. hardware.
79        - Update for change in 2.5.X SCSI proc FS interface.
80        - When negotiation async via an 8bit WDTR message, send
81          an SDTR with an offset of 0 to be sure the target
82          knows we are async.  This works around a firmware defect
83          in the Quantum Atlas 10K.
84        - Implement controller suspend and resume.
85        - Clear PCI error state during driver attach so that we
86          don't disable memory mapped I/O due to a stray write
87          by some other driver probe that occurred before we
88          claimed the controller.
89
90   1.3.9 (May 22nd, 2003)
91        - Fix compiler errors.
92        - Remove S/G splitting for segments that cross a 4GB boundary.
93          This is guaranteed not to happen in Linux.
94        - Add support for scsi_report_device_reset() found in
95          2.5.X kernels.
96        - Add 7901B support.
97        - Simplify handling of the packetized lun Rev A workaround.
98        - Correct and simplify handling of the ignore wide residue
99          message.  The previous code would fail to report a residual
100          if the transaction data length was even and we received
101          an IWR message.
102
103   1.3.8 (April 29th, 2003)
104        - Fix types accessed via the command line interface code.
105        - Perform a few firmware optimizations.
106        - Fix "Unexpected PKT busfree" errors.
107        - Use a sequencer interrupt to notify the host of
108          commands with bad status.  We defer the notification
109          until there are no outstanding selections to ensure
110          that the host is interrupted for as short a time as
111          possible.
112        - Remove pre-2.2.X support.
113        - Add support for new 2.5.X interrupt API.
114        - Correct big-endian architecture support.
115
116   1.3.7 (April 16th, 2003)
117        - Use del_timer_sync() to ensure that no timeouts
118          are pending during controller shutdown.
119        - For pre-2.5.X kernels, carefully adjust our segment
120          list size to avoid SCSI malloc pool fragmentation.
121        - Cleanup channel display in our /proc output.
122        - Workaround duplicate device entries in the mid-layer
123          device list during add-single-device.
124
125   1.3.6 (March 28th, 2003)
126        - Correct a double free in the Domain Validation code.
127        - Correct a reference to free'ed memory during controller
128          shutdown.
129        - Reset the bus on an SE->LVD change.  This is required
130          to reset our transceivers.
131
132   1.3.5 (March 24th, 2003)
133        - Fix a few register window mode bugs.
134        - Include read streaming in the PPR flags we display in
135          diagnostics as well as /proc.
136        - Add PCI hot plug support for 2.5.X kernels.
137        - Correct default precompensation value for RevA hardware.
138        - Fix Domain Validation thread shutdown.
139        - Add a firmware workaround to make the LED blink
140          brighter during packetized operations on the H2A4.
141        - Correct /proc display of user read streaming settings.
142        - Simplify driver locking by releasing the io_request_lock
143          upon driver entry from the mid-layer.
144        - Cleanup command line parsing and move much of this code
145          to aiclib.
146
147   1.3.4 (February 28th, 2003)
148        - Correct a race condition in our error recovery handler.
149        - Allow Test Unit Ready commands to take a full 5 seconds
150          during Domain Validation.
151
152   1.3.2 (February 19th, 2003)
153        - Correct a Rev B. regression due to the GEM318
154          compatibility fix included in 1.3.1.
155
156   1.3.1 (February 11th, 2003)
157        - Add support for the 39320A.
158        - Improve recovery for certain PCI-X errors.
159        - Fix handling of LQ/DATA/LQ/DATA for the
160          same write transaction that can occur without
161          interveining training.
162        - Correct compatibility issues with the GEM318
163          enclosure services device.
164        - Correct data corruption issue that occurred under
165          high tag depth write loads.
166        - Adapt to a change in the 2.5.X daemonize() API.
167        - Correct a "Missing case in ahd_handle_scsiint" panic.
168
169   1.3.0 (January 21st, 2003)
170        - Full regression testing for all U320 products completed.
171        - Added abort and target/lun reset error recovery handler and
172          interrupt coalescing.
173
174   1.2.0 (November 14th, 2002)
175        - Added support for Domain Validation
176        - Add support for the Hewlett-Packard version of the 39320D
177          and AIC-7902 adapters.
178        Support for previous adapters has not been fully tested and should
179        only be used at the customer's own risk.
180
181   1.1.1 (September 24th, 2002)
182        - Added support for the Linux 2.5.X kernel series

187
188   1.0.0 (May 30th, 2002)
189        - Initial driver release.
190

271                      the default tag depth.
272            Examples: tag_info:{{16,32,32,64,8,8,,32,32,32,32,32,32,32,32,32}

291                      The rd_strm_bitmask is a 16 bit hex value in which
292                      each bit represents a target.  Setting the target's
293                      bit to '1' enables read streaming for that
294                      target.  Controllers may be omitted indicating that
295                      they should retain the default read streaming setting.
296             Example: rd_strm:{0x0041}
297                        On Controller 0
298                          enables read streaming for targets 0 and 6.
299                          disables read streaming for targets 1-5,7-15.
300                        All other targets retain the default read
301                        streaming setting.
302             Example: rd_strm:{0x0023,,0xFFFF}
303                        On Controller 0
304                          enables read streaming for targets 1,2, and 5.
305                          disables read streaming for targets 3,4,6-15.

307                          enables read streaming for all targets.
308                        All other targets retain the default read
309                        streaming setting.

384
3854. Additional Notes
386
387   4.1. Known/Unresolved or FYI Issues
388
389        * Under SuSE Linux Enterprise 7, the driver may fail to operate
390          correctly due to a problem with PCI interrupt routing in the
391          Linux kernel.  Please contact SuSE for an updated Linux
392          kernel.
393
394   4.2. Third-Party Compatibility Issues
395
396        * Adaptec only supports Ultra320 hard drives running
397          the latest firmware available. Please check with
398          your hard drive manufacturer to ensure you have the
399          latest version.
400
401   4.3. Operating System or Technology Limitations
402
403        * PCI Hot Plug is untested and may cause the operating system
404          to stop responding.
405        * Luns that are not numbered contiguously starting with 0 might not
406          be automatically probed during system startup.  This is a limitation
407          of the OS.  Please contact your Linux vendor for instructions on
408          manually probing non-contiguous luns.
409        * Using the Driver Update Disk version of this package during OS
410          installation under RedHat might result in two versions of this
411          driver being installed into the system module directory.  This
412          might cause problems with the /sbin/mkinitrd program and/or
413          other RPM packages that try to install system modules.  The best
414          way to correct this once the system is running is to install
415          the latest RPM package version of this driver, available from
416          http://www.adaptec.com.
