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)

|
|
- 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)

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.
|
|
