|
|
|
|
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.
