| 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: |
| |
| verbose |
| |
| :Definition: enable additional informative messages during driver operation. |
| :Possible Values: This option is a flag |
| :Default Value: disabled |
| |
| |
| debug:[value] |
| |
| :Definition: Enables various levels of debugging information |
| :Possible Values: 0x0000 = no debugging, 0xffff = full debugging |
| :Default Value: 0x0000 |
| |
| no_probe |
| |
| 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. |
| |
| 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 |
| |
| no_reset |
| |
| :Definition: Do not reset the bus during the initial probe |
| phase |
| |
| :Possible Values: This option is a flag |
| :Default Value: disabled |
| |
| extended |
| |
| :Definition: Force extended translation on the controller |
| :Possible Values: This option is a flag |
| :Default Value: disabled |
| |
| 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 |
| |
| reverse_scan |
| |
| :Definition: Probe the scsi bus in reverse order, starting |
| with target 15 |
| |
| :Possible Values: This option is a flag |
| :Default Value: disabled |
| |
| 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 |
| |
| 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. |
| |
| :Possible Values: 1 - 253 |
| :Default Value: 32 |
| |
| 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. |
| |
| seltime:[value] |
| |
| :Definition: Specifies the selection timeout value |
| :Possible Values: 0 = 256ms, 1 = 128ms, 2 = 64ms, 3 = 32ms |
| :Default Value: 0 |
| |
| 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. |
| |
| :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: |
| |
| :: |
| |
| 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. |
| |
| 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. |
