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

379
3804. Additional Notes
381
382 4.1. Known/Unresolved or FYI Issues
383
384 * Under SuSE Linux Enterprise 7, the driver may fail to operate
385 correctly due to a problem with PCI interrupt routing in the
386 Linux kernel. Please contact SuSE for an updated Linux
387 kernel.
388
389 4.2. Third-Party Compatibility Issues
390
391 * Adaptec only supports Ultra320 hard drives running
392 the latest firmware available. Please check with
393 your hard drive manufacturer to ensure you have the
394 latest version.
395
396 4.3. Operating System or Technology Limitations
397
398 * PCI Hot Plug is untested and may cause the operating system
399 to stop responding.
400 * Luns that are not numbered contiguously starting with 0 might not
401 be automatically probed during system startup. This is a limitation
402 of the OS. Please contact your Linux vendor for instructions on
403 manually probing non-contiguous luns.
404 * Using the Driver Update Disk version of this package during OS
405 installation under RedHat might result in two versions of this
406 driver being installed into the system module directory. This
407 might cause problems with the /sbin/mkinitrd program and/or
408 other RPM packages that try to install system modules. The best
409 way to correct this once the system is running is to install
410 the latest RPM package version of this driver, available from
411 http://www.adaptec.com.
412
