64 2. Version History
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.
71 1.3.11 (July 11, 2003)
72 - Fix several deadlock issues.
73 - Add 29320ALP and 39320B Id's.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.

385 4. Additional Notes
387 4.1. Known/Unresolved or FYI Issues
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.
394 4.2. Third-Party Compatibility Issues
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.
401 4.3. Operating System or Technology Limitations
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.
