DEC21050 PCI-PCI bridge with multiple controller chips on secondary bus

DEC2115X PCI-PCI bridge with multiple controller chips on secondary bus

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.
