   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 introduced in 6.2.29 that
          could cause 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. 

   Put a .conf file in the /etc/modprobe.d directory 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 omitted 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 omitted 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.

129	3. DEC2115X PCI-PCI bridge with multiple controller chips on secondary bus
130	4. All three SCSI connectors may be used simultaneously without
131	SCSI "stub" effects.
132
133	2. Version History
79778a27 JB	134	7.0 (4th August, 2005)
	135	- Updated driver to use SCSI transport class infrastructure
	136	- Upported sequencer and core fixes from last adaptec released
	137	version of the driver.
1da177e4 LT	138	6.2.36 (June 3rd, 2003)
	139	- Correct code that disables PCI parity error checking.
	140	- Correct and simplify handling of the ignore wide residue
	141	message. The previous code would fail to report a residual
	142	if the transaction data length was even and we received
	143	an IWR message.
	144	- Add support for the 2.5.X EISA framework.
	145	- Update for change in 2.5.X SCSI proc FS interface.
	146	- Correct Domain Validation command-line option parsing.
	147	- When negotiation async via an 8bit WDTR message, send
	148	an SDTR with an offset of 0 to be sure the target
	149	knows we are async. This works around a firmware defect
	150	in the Quantum Atlas 10K.
	151	- Clear PCI error state during driver attach so that we
	152	don't disable memory mapped I/O due to a stray write
	153	by some other driver probe that occurred before we
	154	claimed the controller.
	155
	156	6.2.35 (May 14th, 2003)
	157	- Fix a few GCC 3.3 compiler warnings.
	158	- Correct operation on EISA Twin Channel controller.
	159	- Add support for 2.5.X's scsi_report_device_reset().
	160
	161	6.2.34 (May 5th, 2003)
01dd2fbf	162	- Fix locking regression introduced in 6.2.29 that
6c28f2c0	163	could cause a lock order reversal between the io_request_lock
1da177e4 LT	164	and our per-softc lock. This was only possible on RH9,
	165	SuSE, and kernel.org 2.4.X kernels.
	166
	167	6.2.33 (April 30th, 2003)
	168	- Dynamically disable PCI parity error reporting after
	169	10 errors are reported to the user. These errors are
	170	the result of some other device issuing PCI transactions
	171	with bad parity. Once the user has been informed of the
	172	problem, continuing to report the errors just degrades
	173	our performance.
	174
	175	6.2.32 (March 28th, 2003)
	176	- Dynamically sized S/G lists to avoid SCSI malloc
	177	pool fragmentation and SCSI mid-layer deadlock.
	178
	179	6.2.28 (January 20th, 2003)
	180	- Domain Validation Fixes
	181	- Add ability to disable PCI parity error checking.
	182	- Enhanced Memory Mapped I/O probe
	183
	184	6.2.20 (November 7th, 2002)
	185	- Added Domain Validation.
	186
	187	3. Command Line Options
	188
	189	WARNING: ALTERING OR ADDING THESE DRIVER PARAMETERS
	190	INCORRECTLY CAN RENDER YOUR SYSTEM INOPERABLE.
	191	USE THEM WITH CAUTION.
	192
970e2486	193	Put a .conf file in the /etc/modprobe.d directory and add/edit a
1da177e4 LT	194	line containing 'options aic7xxx aic7xxx=[command[,command...]]' where
	195	'command' is one or more of the following:
	196	-----------------------------------------------------------------
	197	Option: verbose
	198	Definition: enable additional informative messages during
	199	driver operation.
	200	Possible Values: This option is a flag
	201	Default Value: disabled
	202	-----------------------------------------------------------------
	203	Option: debug:[value]
	204	Definition: Enables various levels of debugging information
	205	Possible Values: 0x0000 = no debugging, 0xffff = full debugging
	206	Default Value: 0x0000
	207	-----------------------------------------------------------------
	208	Option: no_probe
	209	Option: probe_eisa_vl
	210	Definition: Do not probe for EISA/VLB controllers.
	211	This is a toggle. If the driver is compiled
	212	to not probe EISA/VLB controllers by default,
	213	specifying "no_probe" will enable this probing.
	214	If the driver is compiled to probe EISA/VLB
	215	controllers by default, specifying "no_probe"
	216	will disable this probing.
	217	Possible Values: This option is a toggle
	218	Default Value: EISA/VLB probing is disabled by default.
	219	-----------------------------------------------------------------
	220	Option: pci_parity
	221	Definition: Toggles the detection of PCI parity errors.
	222	On many motherboards with VIA chipsets,
	223	PCI parity is not generated correctly on the
	224	PCI bus. It is impossible for the hardware to
	225	differentiate between these "spurious" parity
	226	errors and real parity errors. The symptom of
	227	this problem is a stream of the message:
	228	"scsi0: Data Parity Error Detected during address or write data phase"
	229	output by the driver.
	230	Possible Values: This option is a toggle
	231	Default Value: PCI Parity Error reporting is disabled
	232	-----------------------------------------------------------------
	233	Option: no_reset
	234	Definition: Do not reset the bus during the initial probe
	235	phase
	236	Possible Values: This option is a flag
	237	Default Value: disabled
	238	-----------------------------------------------------------------
	239	Option: extended
	240	Definition: Force extended translation on the controller
	241	Possible Values: This option is a flag
	242	Default Value: disabled
	243	-----------------------------------------------------------------
	244	Option: periodic_otag
	245	Definition: Send an ordered tag periodically to prevent
	246	tag starvation. Needed for some older devices
	247	Possible Values: This option is a flag
	248	Default Value: disabled
	249	-----------------------------------------------------------------
	250	Option: reverse_scan
	251	Definition: Probe the scsi bus in reverse order, starting
	252	with target 15
	253	Possible Values: This option is a flag
	254	Default Value: disabled
	255	-----------------------------------------------------------------
	256	Option: global_tag_depth:[value]
	257	Definition: Global tag depth for all targets on all busses.
258	This option sets the default tag depth which
259	may be selectively overridden vi the tag_info
260	option.
261	Possible Values: 1 - 253
262	Default Value: 32
263	-----------------------------------------------------------------
264	Option: tag_info:{{value[,value...]}[,{value[,value...]}...]}
265	Definition: Set the per-target tagged queue depth on a
266	per controller basis. Both controllers and targets
01dd2fbf	267	may be omitted indicating that they should retain
1da177e4 LT	268	the default tag depth.
	269	Examples: tag_info:{{16,32,32,64,8,8,,32,32,32,32,32,32,32,32,32}
	270	On Controller 0
	271	specifies a tag depth of 16 for target 0
	272	specifies a tag depth of 64 for target 3
	273	specifies a tag depth of 8 for targets 4 and 5
	274	leaves target 6 at the default
	275	specifies a tag depth of 32 for targets 1,2,7-15
	276	All other targets retain the default depth.
	277
	278	tag_info:{{},{32,,32}}
	279	On Controller 1
	280	specifies a tag depth of 32 for targets 0 and 2
	281	All other targets retain the default depth.
	282
	283	Possible Values: 1 - 253
	284	Default Value: 32
	285	-----------------------------------------------------------------
	286	Option: seltime:[value]
	287	Definition: Specifies the selection timeout value
	288	Possible Values: 0 = 256ms, 1 = 128ms, 2 = 64ms, 3 = 32ms
	289	Default Value: 0
	290	-----------------------------------------------------------------
	291	Option: dv: {value[,value...]}
	292	Definition: Set Domain Validation Policy on a per-controller basis.
01dd2fbf	293	Controllers may be omitted indicating that
1da177e4 LT	294	they should retain the default read streaming setting.
	295	Example: dv:{-1,0,,1,1,0}
	296	On Controller 0 leave DV at its default setting.
	297	On Controller 1 disable DV.
	298	Skip configuration on Controller 2.
	299	On Controllers 3 and 4 enable DV.
	300	On Controller 5 disable DV.
	301
	302	Possible Values: < 0 Use setting from serial EEPROM.
	303	0 Disable DV
	304	> 0 Enable DV
	305
	306	Default Value: SCSI-Select setting on controllers with a SCSI Select
	307	option for DV. Otherwise, on for controllers supporting
	308	U160 speeds and off for all other controller types.
	309	-----------------------------------------------------------------
	310
	311	Example:
