| 2. 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) |

| |
| 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. |
| |
| |
