722. 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.

420slewrate: {value[,value...]}
421    :Definition: Set IO Cell slew rate on a per-controller basis.
422                      Controllers may be omitted indicating that
423                      they should retain the default slew rate setting.
424
425    :Possible Values: 0 - 15
426    :Default Value: Varies based on chip revision

443amplitude: {value[,value...]}
444    :Definition: Set IO Cell signal amplitude on a per-controller basis.
445                 Controllers may be omitted indicating that
446                 they should retain the default read streaming setting.
447
448    :Possible Values: 1 - 7

466Example::
467
468    options aic79xx aic79xx=verbose,rd_strm:{{0x0041}}
469
470enables verbose output in the driver and turns read streaming on
471for targets 0 and 6 of Controller 0.

4734. Additional Notes
474===================
475
4764.1. 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
4844.2. 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
4924.3. 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.
