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. Software/Hardware Features - Support for the SPI-4 "Ultra320" standard: - 320MB/s transfer rates - Packetized SCSI Protocol at 160MB/s and 320MB/s - Quick Arbitration Selection (QAS) - Retained Training Information (Rev B. ASIC only) - Interrupt Coalescing - Initiator Mode (target mode not currently supported) - Support for the PCI-X standard up to 133MHz - Support for the PCI v2.2 standard - Domain Validation 2.2.

Possible Values: 1 - 7 Default Value: Varies based on chip revision ----------------------------------------------------------------- Example: 'options aic79xx aic79xx=verbose,rd_strm:{{0x0041}}' enables verbose output in the driver and turns read streaming on for targets 0 and 6 of Controller 0. 4. 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.
