+
+2. Version History
+ 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 susupend 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 packtized 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
+ devlice 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 transcievers.
+
+ 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 coalessing.
+
+ 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

+ *** the direction of a technical support representative. ***
+
+ -----------------------------------------------------------------
+ Option: precomp: {value[,value...]}
+ Definition: Set IO Cell precompensation value on a per-controller
+ basis.
+ Controllers may be ommitted indicating that
+ they should retain the default precompensation setting.
+ Example: precomp:{0x1}
+ On Controller 0 set precompensation to 1.
+ Example: precomp:{1,,7}
+ On Controller 0 set precompensation to 1.

+ they should retain the default read streaming setting.
+ Example: amplitude:{0x1}
+ On Controller 0 set amplitude to 1.
+ Example: amplitude :{1,,7}
+ On Controller 0 set amplitude to 1.
+ On Controller 2 set amplitude to 7.
+
+ 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.
+
