72 2. 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)
193 - Added support for the Linux 2.5.X kernel series
194
195 * 1.1.0 (September 17th, 2002)

472
473 4. Additional Notes
474 ===================
475
476 4.1. 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
484 4.2. 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
492 4.3. 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.
