1. No BIOS support
2. DEC21050 PCI-PCI bridge with multiple controller chips on secondary bus
3. DEC2115X PCI-PCI bridge with multiple controller chips on secondary bus
4. All three SCSI connectors may be used simultaneously without
SCSI "stub" effects.
2. Version History
7.0 (4th August, 2005)
- Updated driver to use SCSI transport class infrastructure
- Upported sequencer and core fixes from last adaptec released
version of the driver.
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 "modprobe.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.
