+2. Version History
+
+ 2.0.15 (September 25, 2005)
+ - Added code to enable slowcrc bit during nego
+ table update to slow down CRC interval to be
+ compatible with packetized U320 devices that
+ can't handle a CRC at full speed.
+
+ 2.0.14 (December 23, 2004)
+ - PCI memory space is 512 bytes, not 256.
+ - Fix wrongly calling scsi_adjust_queue_depth() when
+ the scsi device has no request_queue.
+ - Adding module option "slowcrc" to control the
+ setting of that bit in the NEGODAT3 (NEGCONOPTS)
+ register. The LSI chip being used in certain
+ external storage boxes do not allow 320 connection
+ for Rev B of the aic79xx. Turning on this bit
+ works around the bug in the LSI chip. Default is
+ off. To turn on, use kernel/module parameter as:
+
+ aic79xx=slowcrc:1
+
+ - Adding proper PCI ID tables to support
+ hotplugging.
+ - Fix a compilation issue after scsi_sleep() became
+ obsolete, in stead of the new msleep() and
+ ssleep() functions.
+ - Edit Adaptec Customer Support info.
+ - Fix a bug freeing in reserve_io_regions (wrong pointer
+ to free).
+ - "Warnings are errors" is now selectable by the
+ kbuild system -- make it so here.
+ - Fix undefined symbol when compiling aic79xx for 2.6.
+ Also regenerate the aic7xxx reg and seq files.
+ - Plug leaks in aic79xx_osm.c::ahd_linux_dev_reset().
+ Convert AIC to ssleep() and msleep() as
+ scsi_sleep() is no longer available in 2.6.
+ - Fix a double free. If "ahc_alloc()" fails, it
+ frees the "name" argument passed.
+ - Invert the polarity of two tests in the recovery
+ code that could cause the driver to issue a bus
+ reset more quickly than intended. We want to
+ *wait* if we find another SCB that could be the
+ cause of this timeout, not proceed to a bus reset.
+ - As requested by linux-scsi: Add a flag which explicitly
+ forbids/allows the compilation of the firmware across
+ the whole build system.
+ - When doing domain validation, we send commands
+ which do not have a struct request. In this case
+ we cannot just call scsi_populate_tag_msg(), since
+ it dereferences it blindly and oopses the kernel.
+ Now we call scsi_populate_tag_msg() only if the
+ SCSI command has a struct request associated with
+ it.
+
+ 2.0.13 (July 22, 2004)
+ - Fix a compilation issue due to the changed location and name
+ of the "hosts.h" file. Now it resides as <scsi/scsi_host.h>
+ - Add support for 16 byte CDBs.
+
+ 2.0.12 (May 13th, 2004)
+ - Flag driver threads with PF_FREEZE to support software suspend.
+
+ 2.0.11 (May 7th, 2004)
+ - Avoid split-completion bugs in certain PCI-X chipsets by
+ breaking up large completion entry DMAs on ADB boundaries.
+
+ 2.0.10 (April 9th, 2004)
+ - Return "command timeout" status instead of "selection timeout
+ status" to the SCSI mid-layer in response to selection timeouts.
+ While the latter may seem more correct, the mid-layer will not
+ offline devices suffering from persistent selection timeouts.
+ This leads to extremely long recovery times for devices that
+ go missing. Returning command timeout status causes the mid-layer
+ to enter recovery and eventually offline persistently missing
+ devices.
+
+ 2.0.9 (March 29th, 2004)
+ - Abort all pending transactions on a target in response to
+ a selection timeout. This greatly increases the speed with
+ which we recover when a device "goes missing".
+
+ 2.0.8 (March 7th, 2004)
+ - Fix PCI device/vendor ID mask for the 7901B probe entry
+ so the driver will successfully attach to 7901B parts
+ down on motherboards.
+
+ 2.0.7 (February 24th, 2004)
+ - Implement delay on I/O after delivery of a Target Reset.
+ - Correct deregistration of sysrq handler when multiple
+ controllers are detected.
+
+ 2.0.6 (February 6th, 2004)
+ - Force a renegotiation on all inqury commands so that
+ the negotiated transfer parameters are correct even
+ if the device has been externally reset since our last
+ command. Devices are not allowed to report unit attention
+ conditions in response to inquiry requests otherwise we'd
+ not need to treat inquiry commands specially.
+ - Remove all vestiges of pre-2.4.X support.
+ - Close a very rare race-condition in RevA 790X controllers.
+ If both FIFOs are allocated before the sequencer's idle
+ loop is able to service the FIFO that was allocated first,
+ the sequencer could handle them out of order. This could
+ lead to a deadlock where the FIFO attached to the SCSI bus
+ is being serviced by the sequencer, but the other FIFO is
+ required to handle a snapshot. The sequencer now detects
+ this condition and always handles FIFOs that are not currently
+ on the bus first.
+ - Close a few race conditions by adding critical section
+ markers into the firmware. These windows might have caused
+ issues during error recovery.
+ - Switch the complete DMA SCB list to a tailq so that multiple
+ SCBs completing with non-zero status do not interfere with
+ the state for the SCB currently being uploaded.
+ - Use the comparison of a kernel and a sequencer qfreeze
+ count to control the freezing of outgoing selections. This
+ allows the kernel to handle non-zero SCB completions without
+ having to clear firmware critical sections.
+ - Change the completion FIFO mechanism so that all completion
+ entries are guaranteed aligned on a 64bit boundary. This
+ avoids SCB DMA engine bugs that are triggered if the transfer
+ is interrupted (e.g. PCI disconnect) on a non-aligned boundary.
+ In some cases, these bugs would result in duplicate completions.
+ - Use one byte in the new completion entry to indicate if the
+ SCB completed without a residual or non-zero SCSI status. This
+ avoids an extra memory reference in our interrupt handler.
+
+ 2.0.5 (December 22nd, 2003)
+ - Correct a bug preventing the driver from renegotiating
+ during auto-request sense operations when a check
+ condition occurred for a zero length command.
+ - Sniff sense information returned by targets for unit
+ attention errors that may indicate that the device has
+ been changed. If we see such status for non Domain
+ Validation related commands, start a DV scan for the
+ target. In the past, DV would only occur for hot-plugged
+ devices if no target had been previously probed for a
+ particular ID. This change guarantees that the DV process
+ will occur even if the user swaps devices without any
+ interveining I/O to tell us that a device has gone missing.
+ The old behavior, among other things, would fail to spin up
+ drives that were hot-plugged since the Linux mid-layer
+ will only spin-up drives on initial attach.
+ - Correct several issues in the rundown of the good status
+ FIFO during error recovery. The typical failure scenario
+ evidenced by this defect was the loss of several commands
+ under high load when several queue full conditions occured
+ back to back.
+
+ 2.0.4 (November 6th, 2003)
+ - Support the 2.6.0-test9 kernel
+ - Fix rare deadlock caused by using del_timer_sync from within
+ a timer handler.
+
+ 2.0.3 (October 21st, 2003)
+ - On 7902A4 hardware, use the slow slew rate for transfer
+ rates slower than U320. This behavior matches the Windows
+ driver.
+ - Fix some issues with the ahd_flush_qoutfifo() routine.
+ - Add a delay in the loop waiting for selection activity
+ to cease. Otherwise we may exhaust the loop counter too
+ quickly on fast machines.
+ - Return to processing bad status completions through the
+ qoutfifo. This reduces the amount of time the controller
+ is paused for these kinds of errors.
+ - Move additional common routines to the aiclib OSM library
+ to reduce code duplication.
+ - Leave removal of softcs from the global list of softcs to
+ the OSM. This allows us to avoid holding the list_lock during
+ device destruction.
+ - Enforce a bus settle delay for bus resets that the
+ driver initiates.
+ - Fall back to basic DV for U160 devices that lack an
+ echo buffer.
+
+ 2.0.2 (September 4th, 2003)
+ - Move additional common routines to the aiclib OSM library
+ to reduce code duplication.
+ - Avoid an inadvertant reset of the controller during the
+ memory mapped I/O test should the controller be left in
+ the reset state prior to driver initialization. On some
+ systems, this extra reset resulted in a system hang due
+ to a chip access that occurred too soon after reset.
+ - Correct an endian bug in ahd_swap_with_next_hscb. This
+ corrects strong-arm support.
+ - Reset the bus for transactions that timeout waiting for
+ the bus to go free after a disconnect or command complete
+ message.
+
+ 2.0.1 (August 26th, 2003)
+ - Add magic sysrq handler that causes a card dump to be output
+ to the console for each controller.
+ - Avoid waking the mid-layer's error recovery handler during
+ timeout recovery by returning DID_ERROR instead of DID_TIMEOUT
+ for timed-out commands that have been aborted.
+ - Move additional common routines to the aiclib OSM library
+ to reduce code duplication.
+
+ 2.0.0 (August 20th, 2003)
+ - Remove MMAPIO definition and allow memory mapped
+ I/O for any platform that supports PCI.
+ - Avoid clearing ENBUSFREE during single stepping to avoid
+ spurious "unexpected busfree while idle" messages.
+ - Correct deadlock in ahd_run_qoutfifo() processing.
+ - Optimize support for the 7901B.
+ - Correct a few cases where an explicit flush of pending
+ register writes was required to ensure acuracy in delays.
+ - Correct problems in manually flushing completed commands
+ on the controller. The FIFOs are now flushed to ensure
+ that completed commands that are still draining to the
+ host are completed correctly.
+ - Correct incomplete CDB delivery detection on the 790XB.
+ - Ignore the cmd->underflow field since userland applications
+ using the legacy command pass-thru interface do not set
+ it correctly. Honoring this field led to spurious errors
+ when users used the "scsi_unique_id" program.
+ - Perform timeout recovery within the driver instead of relying
+ on the Linux SCSI mid-layer to perform this function. The
+ mid-layer does not know the full state of the SCSI bus and
+ is therefore prone to looping for several minutes to effect
+ recovery. The new scheme recovers within 15 seconds of the
+ failure.
+ - Correct support for manual termination settings.
+ - Increase maximum wait time for serial eeprom writes allowing
+ writes to function correctly.
+
+ 1.3.12 (August 11, 2003)
+ - Implement new error recovery thread that supercedes the existing
+ Linux SCSI error recovery code.
+ - Fix termination logic for 29320ALP.
+ - Fix SEEPROM delay to compensate for write ops taking longer.
+
+ 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 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.

+ Definition: Set IO Cell signal amplitude on a per-controller basis.
+ Controllers may be ommitted indicating that
+ 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.

+
+2. Version History
+
+ 6.3.11 (December 23, 2004)
+ - Fix wrongly calling scsi_adjust_queue_depth() when
+ the scsi device has no request_queue.
+ - Adding proper PCI ID tables to support
+ hotplugging.
+ - Fix a compilation issue after scsi_sleep() became
+ obsolete, in stead of the new msleep() and
+ ssleep() functions.
+ - Edit Adaptec Customer Support info.
+ - "Warnings are errors" is now selectable by the
+ kbuild system -- make it so here.
+ - Fix undefined symbol when compiling aic79xx for 2.6.
+ Also regenerate the aic7xxx reg and seq files.
+ - Fix a double free. If "ahc_alloc()" fails, it
+ frees the "name" argument passed.
+ - As requested by linux-scsi: Add a flag which explicitly
+ forbids/allows the compilation of the firmware across
+ the whole build system.
+ - When doing domain validation, we send commands
+ which do not have a struct request. In this case
+ we cannot just call scsi_populate_tag_msg(), since
+ it dereferences it blindly and oopses the kernel.
+ Now we call scsi_populate_tag_msg() only if the
+ SCSI command has a struct request associated with
+ it.
+
+ 6.3.10 (July 22, 2004)
+ - Fix a compilation issue due to the changed location and name
+ of the "hosts.h" file. Now it resides as <scsi/scsi_host.h>
+ - Add support for 16 byte CDBs.
+
+ 6.3.9 (May 13th, 2004)
+ - Flag driver threads with PF_FREEZE to support software suspend.
+
+ 6.3.8 (April 9th, 2004)
+ - Return "command timeout" status instead of "selection timeout
+ status" to the SCSI mid-layer in response to selection timeouts.
+ While the latter may seem more correct, the mid-layer will not
+ offline devices suffering from persistent selection timeouts.
+ This leads to extremely long recovery times for devices that
+ go missing. Returning command timeout status causes the mid-layer
+ to enter recovery and eventually offline persistently missing
+ devices.
+
+ 6.3.7 (March 29th, 2004)
+ - Abort all pending transactions on a target in response to
+ a selection timeout. This greatly increases the speed with
+ which we recover when a device "goes missing".
+
+ 6.3.6 (February 24th, 2004)
+ - Implement delay on I/O after delivery of a Target Reset.
+ - Correct deregistration of sysrq handler when multiple
+ controllers are detected.
+ - Correct timeout recovery issues found while debugging
+ active/active failover on an external RAID controller.
+
+ 6.3.5 (February 22nd, 2004)
+ - Force a renegotiation on all inqury commands so that
+ the negotiated transfer parameters are correct even
+ if the device has been externally reset since our last
+ command. Devices are not allowed to report unit attention
+ conditions in response to inquiry requests otherwise we'd
+ not need to treat inquiry commands specially.
+ - Remove all vestiges of pre-2.4.X support.
+ - Move all lock and DMA API support to the aiclib.
+
+ 6.3.4 (December 22nd, 2003)
+ - Provide a better description string for the 2915/30LP.
+ - Sniff sense information returned by targets for unit
+ attention errors that may indicate that the device has
+ been changed. If we see such status for non Domain
+ Validation related commands, start a DV scan for the
+ target. In the past, DV would only occur for hot-plugged
+ devices if no target had been previously probed for a
+ particular ID. This change guarantees that the DV process
+ will occur even if the user swaps devices without any
+ interveining I/O to tell us that a device has gone missing.
+ The old behavior, among other things, would fail to spin up
+ drives that were hot-plugged since the Linux mid-layer
+ will only spin-up drives on initial attach.
+
+ 6.3.3 (November 6th, 2003)
+ - Support the 2.6.0-test9 kernel
+ - Fix rare deadlock caused by using del_timer_sync from within
+ a timer handler.
+
+ 6.3.2 (October 28th, 2003)
+ - Enforce a bus settle delay for bus resets that the
+ driver initiates.
+ - Fall back to basic DV for U160 devices that lack an
+ echo buffer.
+ - Correctly detect that left over BIOS data has not
+ been initialized when the CHPRST status bit is set
+ during driver initialization.
+
+ 6.3.1 (October 21st, 2003)
+ - Fix a compiler error when building with only EISA or PCI
+ support compiled into the kernel.
+ - Add chained dependencies to both the driver and aicasm Makefiles
+ to avoid problems with parallel builds.
+ - Move additional common routines to the aiclib OSM library
+ to reduce code duplication.
+ - Fix a bug in the testing of the AHC_TMODE_WIDEODD_BUG that
+ could cause target mode operations to hang.
+ - Leave removal of softcs from the global list of softcs to
+ the OSM. This allows us to avoid holding the list_lock during
+ device destruction.
+
+ 6.3.0 (September 8th, 2003)
+ - Move additional common routines to the aiclib OSM library
+ to reduce code duplication.
+ - Bump minor number to reflect change in error recovery strategy.
+
+ 6.2.38 (August 31st, 2003)
+ - Avoid an inadvertant reset of the controller during the
+ memory mapped I/O test should the controller be left in
+ the reset state prior to driver initialization. On some
+ systems, this extra reset resulted in a system hang due
+ to a chip access that occurred too soon after reset.
+ - Move additional common routines to the aiclib OSM library
+ to reduce code duplication.
+ - Add magic sysrq handler that causes a card dump to be output
+ to the console for each controller.
+
+ 6.2.37 (August 12th, 2003)
+ - Perform timeout recovery within the driver instead of relying
+ on the Linux SCSI mid-layer to perform this function. The
+ mid-layer does not know the full state of the SCSI bus and
+ is therefore prone to looping for several minutes to effect
+ recovery. The new scheme recovers within 15 seconds of the
+ failure.
+ - Support writing 93c56/66 SEEPROM on newer cards.
+ - Avoid clearing ENBUSFREE during single stepping to avoid
+ spurious "unexpected busfree while idle" messages.
+ - Enable the use of the "Auto-Access-Pause" feature on the
+ aic7880 and aic7870 chips. It was disabled due to an
+ oversight. Using this feature drastically reduces command
+ delivery latency.
+
+ 6.2.36 (June 3rd, 2003)
+ - Correct code that disables PCI parity error checking.
+ - 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.
+ - Add support for the 2.5.X EISA framework.
+ - Update for change in 2.5.X SCSI proc FS interface.
+ - Correct Domain Validation command-line option parsing.
+ - 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.
+ - 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.
+
+ 6.2.35 (May 14th, 2003)
+ - Fix a few GCC 3.3 compiler warnings.
+ - Correct operation on EISA Twin Channel controller.
+ - Add support for 2.5.X's scsi_report_device_reset().
+
+ 6.2.34 (May 5th, 2003)
+ - Fix locking regression instroduced in 6.2.29 that
+ could cuase a lock order reversal between the io_request_lock
+ and our per-softc lock. This was only possible on RH9,
+ SuSE, and kernel.org 2.4.X kernels.
+
+ 6.2.33 (April 30th, 2003)
+ - Dynamically disable PCI parity error reporting after
+ 10 errors are reported to the user. These errors are
+ the result of some other device issuing PCI transactions
+ with bad parity. Once the user has been informed of the
+ problem, continuing to report the errors just degrades
+ our performance.
+
+ 6.2.32 (March 28th, 2003)
+ - Dynamically sized S/G lists to avoid SCSI malloc
+ pool fragmentation and SCSI mid-layer deadlock.
+
+ 6.2.28 (January 20th, 2003)
+ - Domain Validation Fixes
+ - Add ability to disable PCI parity error checking.
+ - Enhanced Memory Mapped I/O probe
+
+ 6.2.20 (November 7th, 2002)
+ - Added Domain Validation.
+
+3. Command Line Options
+
+ WARNING: ALTERING OR ADDING THESE DRIVER PARAMETERS
+ INCORRECTLY CAN RENDER YOUR SYSTEM INOPERABLE.
+ USE THEM WITH CAUTION.
+
+ Edit the file "modules.conf" in the directory /etc and add/edit a
+ line containing 'options aic7xxx aic7xxx=[command[,command...]]' where
+ 'command' is one or more of the following:
+ -----------------------------------------------------------------
+ Option: verbose
+ Definition: enable additional informative messages during
+ driver operation.
+ Possible Values: This option is a flag
+ Default Value: disabled
+ -----------------------------------------------------------------
+ Option: debug:[value]
+ Definition: Enables various levels of debugging information
+ Possible Values: 0x0000 = no debugging, 0xffff = full debugging
+ Default Value: 0x0000
+ -----------------------------------------------------------------
+ Option: no_probe
+ Option: probe_eisa_vl
+ Definition: Do not probe for EISA/VLB controllers.
+ This is a toggle. If the driver is compiled
+ to not probe EISA/VLB controllers by default,
+ specifying "no_probe" will enable this probing.
+ If the driver is compiled to probe EISA/VLB
+ controllers by default, specifying "no_probe"
+ will disable this probing.
+ Possible Values: This option is a toggle
+ Default Value: EISA/VLB probing is disabled by default.
+ -----------------------------------------------------------------
+ Option: pci_parity
+ Definition: Toggles the detection of PCI parity errors.
+ On many motherboards with VIA chipsets,
+ PCI parity is not generated correctly on the
+ PCI bus. It is impossible for the hardware to
+ differentiate between these "spurious" parity
+ errors and real parity errors. The symptom of
+ this problem is a stream of the message:
+ "scsi0: Data Parity Error Detected during address or write data phase"
+ output by the driver.
+ Possible Values: This option is a toggle
+ Default Value: PCI Parity Error reporting is disabled
+ -----------------------------------------------------------------
+ Option: no_reset
+ Definition: Do not reset the bus during the initial probe
+ phase
+ Possible Values: This option is a flag
+ Default Value: disabled
+ -----------------------------------------------------------------
+ Option: extended
+ Definition: Force extended translation on the controller
+ Possible Values: This option is a flag
+ Default Value: disabled
+ -----------------------------------------------------------------
+ Option: periodic_otag
+ Definition: Send an ordered tag periodically to prevent
+ tag starvation. Needed for some older devices
+ Possible Values: This option is a flag
+ Default Value: disabled
+ -----------------------------------------------------------------
+ Option: reverse_scan
+ Definition: Probe the scsi bus in reverse order, starting
+ with target 15
+ Possible Values: This option is a flag
+ Default Value: disabled
+ -----------------------------------------------------------------
+ Option: global_tag_depth:[value]
+ Definition: Global tag depth for all targets on all busses.
+ This option sets the default tag depth which
+ may be selectively overridden vi the tag_info
+ option.
+ Possible Values: 1 - 253
+ Default Value: 32
+ -----------------------------------------------------------------
+ Option: tag_info:{{value[,value...]}[,{value[,value...]}...]}
+ Definition: Set the per-target tagged queue depth on a
+ per controller basis. Both controllers and targets
+ may be ommitted indicating that they should retain
+ the default tag depth.
+ Examples: tag_info:{{16,32,32,64,8,8,,32,32,32,32,32,32,32,32,32}
+ On Controller 0
+ specifies a tag depth of 16 for target 0
+ specifies a tag depth of 64 for target 3
+ specifies a tag depth of 8 for targets 4 and 5
+ leaves target 6 at the default
+ specifies a tag depth of 32 for targets 1,2,7-15
+ All other targets retain the default depth.
+
+ tag_info:{{},{32,,32}}
+ On Controller 1
+ specifies a tag depth of 32 for targets 0 and 2
+ All other targets retain the default depth.
+
+ Possible Values: 1 - 253
+ Default Value: 32
+ -----------------------------------------------------------------
+ Option: seltime:[value]
+ Definition: Specifies the selection timeout value
+ Possible Values: 0 = 256ms, 1 = 128ms, 2 = 64ms, 3 = 32ms
+ Default Value: 0
+ -----------------------------------------------------------------
+ Option: dv: {value[,value...]}
+ Definition: Set Domain Validation Policy on a per-controller basis.
+ Controllers may be ommitted indicating that
+ they should retain the default read streaming setting.
+ Example: dv:{-1,0,,1,1,0}
+ On Controller 0 leave DV at its default setting.
+ On Controller 1 disable DV.
+ Skip configuration on Controller 2.
+ On Controllers 3 and 4 enable DV.
+ On Controller 5 disable DV.
+
+ Possible Values: < 0 Use setting from serial EEPROM.
+ 0 Disable DV
+ > 0 Enable DV
+
+ Default Value: SCSI-Select setting on controllers with a SCSI Select
+ option for DV. Otherwise, on for controllers supporting
+ U160 speeds and off for all other controller types.
+ -----------------------------------------------------------------
+
+ Example:
+ options aic7xxx aic7xxx=verbose,no_probe,tag_info:{{},{,,10}},seltime:1
+ enables verbose logging, Disable EISA/VLB probing,
+ and set tag depth on Controller 1/Target 2 to 10 tags.
