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) 196 - Added support for four additional SCSI products: 197 ASC-39320, ASC-29320, ASC-29320LP, AIC-7901. 198 199 * 1.0.0 (May 30th, 2002) 200 - Initial driver release. 201 202 * 2.1.

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. 509 510 5115.
