Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

+ 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
+ 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.
