Version History + + 3.0 (December 1st, 2005) + - Updated driver to use SCSI transport class infrastructure + - Upported sequencer and core fixes from adaptec released + version 2.0.15 of the driver. + + 1.3.11 (July 11, 2003) + - Fix several deadlock issues. + - Add 29320ALP and 39320B Id's. + + 1.3.10 (June 3rd, 2003) + - Align the SCB_TAG field on a 16byte boundary. This avoids + SCB corruption on some PCI-33 busses. + - Correct non-zero luns on Rev B. hardware. + - Update for change in 2.5.X SCSI proc FS interface. + - When negotiation async via an 8bit WDTR message, send + an SDTR with an offset of 0 to be sure the target + knows we are async. This works around a firmware defect + in the Quantum Atlas 10K. + - Implement controller suspend and resume. + - Clear PCI error state during driver attach so that we + don't disable memory mapped I/O due to a stray write + by some other driver probe that occurred before we + claimed the controller. + + 1.3.9 (May 22nd, 2003) + - Fix compiler errors. + - Remove S/G splitting for segments that cross a 4GB boundary. + This is guaranteed not to happen in Linux. + - Add support for scsi_report_device_reset() found in + 2.5.X kernels. + - Add 7901B support. + - Simplify handling of the packetized lun Rev A workaround. + - Correct and simplify handling of the ignore wide residue + message. The previous code would fail to report a residual + if the transaction data length was even and we received + an IWR message. + + 1.3.8 (April 29th, 2003) + - Fix types accessed via the command line interface code. + - Perform a few firmware optimizations. + - Fix "Unexpected PKT busfree" errors. + - Use a sequencer interrupt to notify the host of + commands with bad status. We defer the notification + until there are no outstanding selections to ensure + that the host is interrupted for as short a time as + possible. + - Remove pre-2.2.X support. + - Add support for new 2.5.X interrupt API. + - Correct big-endian architecture support. + + 1.3.7 (April 16th, 2003) + - Use del_timer_sync() to ensure that no timeouts + are pending during controller shutdown. + - For pre-2.5.X kernels, carefully adjust our segment + list size to avoid SCSI malloc pool fragmentation. + - Cleanup channel display in our /proc output. + - Workaround duplicate device entries in the mid-layer + device list during add-single-device. + + 1.3.6 (March 28th, 2003) + - Correct a double free in the Domain Validation code. + - Correct a reference to free'ed memory during controller + shutdown. + - Reset the bus on an SE->LVD change. This is required + to reset our transceivers. + + 1.3.5 (March 24th, 2003) + - Fix a few register window mode bugs. + - Include read streaming in the PPR flags we display in + diagnostics as well as /proc. + - Add PCI hot plug support for 2.5.X kernels. + - Correct default precompensation value for RevA hardware. + - Fix Domain Validation thread shutdown. + - Add a firmware workaround to make the LED blink + brighter during packetized operations on the H2A4. + - Correct /proc display of user read streaming settings. + - Simplify driver locking by releasing the io_request_lock + upon driver entry from the mid-layer. + - Cleanup command line parsing and move much of this code + to aiclib. + + 1.3.4 (February 28th, 2003) + - Correct a race condition in our error recovery handler. + - Allow Test Unit Ready commands to take a full 5 seconds + during Domain Validation. + + 1.3.2 (February 19th, 2003) + - Correct a Rev B. regression due to the GEM318 + compatibility fix included in 1.3.1. + + 1.3.1 (February 11th, 2003) + - Add support for the 39320A. + - Improve recovery for certain PCI-X errors. + - Fix handling of LQ/DATA/LQ/DATA for the + same write transaction that can occur without + interveining training. + - Correct compatibility issues with the GEM318 + enclosure services device. + - Correct data corruption issue that occurred under + high tag depth write loads. + - Adapt to a change in the 2.5.X daemonize() API. + - Correct a "Missing case in ahd_handle_scsiint" panic. + + 1.3.0 (January 21st, 2003) + - Full regression testing for all U320 products completed. + - Added abort and target/lun reset error recovery handler and + interrupt coalescing. + + 1.2.0 (November 14th, 2002) + - Added support for Domain Validation + - Add support for the Hewlett-Packard version of the 39320D + and AIC-7902 adapters. + Support for previous adapters has not been fully tested and should + only be used at the customer's own risk. + + 1.1.1 (September 24th, 2002) + - Added support for the Linux 2.5.X kernel series + + 1.1.0 (September 17th, 2002) + - Added support for four additional SCSI products: + ASC-39320, ASC-29320, ASC-29320LP, AIC-7901. + + 1.0.0 (May 30th, 2002) + - Initial driver release. + + 2.1.

Additional Notes + + 4.1. Known/Unresolved or FYI Issues + + * Under SuSE Linux Enterprise 7, the driver may fail to operate + correctly due to a problem with PCI interrupt routing in the + Linux kernel. Please contact SuSE for an updated Linux + kernel. + + 4.2. Third-Party Compatibility Issues + + * Adaptec only supports Ultra320 hard drives running + the latest firmware available. Please check with + your hard drive manufacturer to ensure you have the + latest version. + + 4.3. Operating System or Technology Limitations + + * PCI Hot Plug is untested and may cause the operating system + to stop responding. + * Luns that are not numbered contiguously starting with 0 might not + be automatically probed during system startup. This is a limitation + of the OS. Please contact your Linux vendor for instructions on + manually probing non-contiguous luns. + * Using the Driver Update Disk version of this package during OS + installation under RedHat might result in two versions of this + driver being installed into the system module directory. This + might cause problems with the /sbin/mkinitrd program and/or + other RPM packages that try to install system modules. The best + way to correct this once the system is running is to install + the latest RPM package version of this driver, available from + http://www.adaptec.com. + + +5.
