64	2. 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
183	
184	   1.1.0 (September 17th, 2002)
185	        - Added support for four additional SCSI products:
186	          ASC-39320, ASC-29320, ASC-29320LP, AIC-7901.
187	
188	   1.0.0 (May 30th, 2002)

271	                      the default tag depth.
272	            Examples: tag_info:{{16,32,32,64,8,8,,32,32,32,32,32,32,32,32,32}
273	                        On Controller 0
274	                          specifies a tag depth of 16 for target 0

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.

384	
385	4. 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.
