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) 189 - Initial driver release. 190 191 2.1.

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. 417 418 4195.
